There are no new features. VERSION 1.24.0 ============== Noteworthy incompatible changes ------------------------------- * If your roff(7) documents follow any of the requests `cf`, `hpf`, `hpfa`, `mso`, `msoquiet`, `nx`, `open`, `opena`, `so`, `soquiet`, or `trf` with a comment after their file name argument, and did not place that comment immediately after the file name, you are likely to get a diagnostic message resembling the following. warning: cannot open macro file 'e.tmac ': No such file or directory Or, less likely, the formatter will open the wrong file, one with spaces at the end of its name. That is because these requests are now able to process file names containing space characters. (This change also makes the request syntax consistent with that of `ds`, `as`, and others.) A quick fix is to place the comment escape sequence as early as possible. For example, we would change: .mso e.tmac \" Load Eric Allman's package. to: .mso e.tmac\" Load Eric Allman's package. to tell the formatter to load the "e.tmac" file rather than "e.tmac ". See the items below for further details. * If your roff(7) documents specify a file name that starts with a neutral double quote (") to any of the requests `cf`, `hpf`, `hpfa`, `mso`, `msoquiet`, `nx`, `open`, `opena`, `so`, `soquiet`, or `trf`, you are likely to get a diagnostic message, or the formatter will open a file of the same name except for the leading neutral double quote. That is because these requests are now able to process file names containing leading space characters. (This change also makes the request syntax consistent with that of `ds`, `as`, and others.) The solution is to add an additional neutral double quote to the start of the file name argument. For example, we would change: .so "5150".lrc to: .so ""5150".lrc to tell the formatter to read a file named '"5150".lrc', where the neutral single quotes bracket the file name. * groff mdoc(7)'s font customization feature, undocumented but analogous to that of 4.4BSD mdoc, now expects the strings that designate font names to be precisely that: font _names_ (or abstract styles, or mounting positions), rather than arbitrary *roff syntax. (String interpolations remain acceptable, as long as what they interpolate is a valid argument to the `ft` request or `\f[xxx]` escape sequence.) * Support for terminal devices using the CCSID 1047 (EBCDIC) encoding has been withdrawn. See below for motivation and a workaround. troff ----- * troff now recognizes an -S option, which "locks" safer mode, rejecting any subsequent specification of -U on the command line with an error diagnostic. * The `cf` request is now disabled in safer mode; as with `pi` and `sy`, you must specify troff's "unsafe mode" option `-U` to use it. Alternatively, use the `trf` request, available since groff 0.6 (circa 1990), to embed a file in GNU troff's output while discarding characters (most C0 and C1 controls) that are invalid as GNU troff input--and incidentally also undefined in GNU troff output. * The `hpfcode` request now emits an error when used, advising of its planned withdrawal, but then proceeds with normal behavior. The documented replacement mechanism, the `hcode` request, has existed since groff 1.02 (June 1991) at the latest. * The `mso` request no longer attempts to open a macro file named, say, "tmac.s" if "s.tmac" was specified as the argument and not found, nor vice versa. This feature was a convenience for some old AT&T troff installations, but few of those remain in the field, and of those that we know to survive, few use a macro file naming convention for which this feature is any help. (DWB 3.3 and Solaris do not, and we think other System V troffs don't, either. Only Plan 9 troff does.) `mso` now simply processes the macro search path for a file name matching the request argument, and succeeds or fails depending on an exact match. If you desire this functionality for portability (keeping in mind that `mso` is itself a groff extension), consider the following. .\" Load the ms package, whatever it might be named. .\" troffs without groff extensions must know its full path. .if !\n(.g .so /path/to/tmac.s .\" The following requests do nothing on non-GNU troffs. .do msoquiet s.tmac\" If file present, defines `LP` macro. .do if !d LP .msoquiet tmac.s * GNU troff no longer accepts nonpositive page lengths. Attempting to set one with the `pl` request clamps the page length to the vertical motion quantum as `ll` does with the horizontal motion quantum in AT&T and GNU troffs. * GNU troff no longer accepts a newline as a delimiter for the parameterized escape sequences `\A`, `\b`, `\o`, `\w`, `\X`, and `\Z`. * GNU troff no longer accepts C0 controls or Latin-1 Supplement characters in identifiers. We prohibit C0 controls to make the language less tolerant of unreadable input, and Latin-1 Supplement code points to enable us to pivot to reading UTF-8-encoded input in a future release. (Thus, we plan for Latin-1 Supplement characters to again be accepted in identifiers, but only as components of multibyte UTF-8 sequences.) * The `color`, `cp`, `kern`, `linetabs`, and `vpt` requests now interpret arguments with negative values as instructions to disable the corresponding feature, using the *roff integer-to-Boolean conversion idiom instead of the C/C++ one. Thus, if you invoke these requests with a register interpolation as an argument, the outcome agrees with an `if` test of the register's value. * GNU troff now implements saturating rather than wrapping integer arithmetic. Where before overflow would cause an error diagnostic and abort evaluation of the expression, the formatter now emits a warning diagnostic in the "range" category and continues evaluation. * GNU troff now strips a leading neutral double quote from the argument to the `cf`, `hpf`, `hpfa`, `lf`, `mso`, `msoquiet`, `nx`, `pi`, `pso`, `so`, `soquiet`, `sy`, and `trf` requests, and the second argument to the `open` and `opena` requests, allowing it to contain embedded leading spaces. * GNU troff now accepts space characters in the argument to the `cf`, `hpf`, `hpfa`, `lf`, `mso`, `msoquiet`, `nx`, `so`, `soquiet`, and `trf` requests, and the second argument to the `open` and `opena` requests. See "soelim" below. * The foregoing two changes make the syntax of the listed requests consistent with that of `ds`, `as`, and others that take arguments that the formatter reads to the next newline. * The "number" warning category has been withdrawn. The diagnostic that formerly used it has been promoted to an error. * The "el" warning category has been withdrawn. If enabled (which it was not by default), the formatter would emit a diagnostic if it inferred an imbalance between `ie` and `el` requests. Unfortunately its technique wasn't reliable and sometimes spuriously issued these warnings, and making it perfectly reliable did not look tractable. We recommend using brace escape sequences `\{` and `\}` to ensure that your control flow structures remain maintainable. * The "right-brace" warning category has been withdrawn. If enabled (which it was not by default), the formatter would emit a diagnostic in exactly one circumstance: when a numeric expression was expected (as, for instance, the second argument to an `nr` request) but a right brace escape sequence `\}` was encountered instead. This diagnostic still issues, but it is now an error. * GNU troff now performs some limited processing/transformation of the argument to the `\X` escape sequence and its counterpart `device` request, to address the requirement that some documents have to pass metadata that must encode non-ASCII characters in device extension commands. (For example, a document author may desire a document's section headings containing non-ASCII code points to appear correctly in PDF bookmarks. Further, GNU troff encodes its output page description language only in ASCII.) This change is expected to be of significance mainly to developers of output drivers for groff; groff_diff(7) describes the transformations. If you have been using `\X` or `.device` to pass ASCII data to the output driver as a device extension command and require that it remain precisely as-is, use the `\!` escape sequence or `output` request, and prefix your data with "x X ", the device-independent troff means of expressing a device extension command (see groff_out(5)). * In nroff mode (in other words, when producing output for devices that claim to be terminals), the formatter now reports warning diagnostics regarding certain output problems using units of lines (vertically) and character cells [ens] (horizontally) instead of inches (or the unit configured with the `warnscale` request) to describe the drawing position where the problem occurred. * The device-independent page description language produced by GNU troff now reports unbreakable spaces (those produced with the `\~` escape sequence) as word boundaries with the documentary 'w' command, just as it does for regular breakable spaces. * A new request, `hydefault`, and read-only register, `.hydefault`, manage the default automatic hyphenation mode of an environment. This resolves a long-standing problem of *roff formatting. When processing input like this, .nh and we temporarily shut off automatic hyphenation, .hy the foregoing request would not do exactly what we expect. AT&T and other troffs apply a hyphenation mode of 1 to the final input line (and subsequent ones), rather than restoring the mode in use before the `nh` request. Apart from overturning user expectations, for GNU troff "1" is not an appropriate mode for its English hyphenation patterns. (For example, "alibi" would break as "ali-bi" instead of "al-ibi" after this argumentless `hy` invocation.) With updates to groff's localization files accompanying this release, the foregoing input now works as desired. * A new read-only, string-valued register, `.trap`, interpolates the name of the next page location trap after the drawing position. * New registers `.it`, `.itc`, and `.itm` are available. These read-only (and, in the case of `.itm`, string-valued) registers report the number of lines remaining in a pending input trap, a Boolean indication of whether that pending input trap honors output line continuation (cf. the `it` and `itc` requests), and the name of the macro associated with the pending input trap, respectively. * A new request, `pchar`, reports to the standard error stream details of any class or ordinary, special, or indexed character arguments. * A new request, `pcolor`, reports to the standard error stream details of each color name specified as an argument, including its color space identifier and channel value assignments. Without arguments, all defined colors are listed. (A device's default stroke and/or fill colors, "default", are not listed since they are immutable and their details unknown to the formatter.) * A new request, `pcomposite`, reports to the standard error stream the list of configured composite character mappings. * A new request, `pfp`, reports to the standard error stream the list of occupied font mounting positions and the corresponding abstract style name or font information. * A new request, `pftr`, reports to the standard error stream the list of configured font translations. * A new request, `phw`, reports to the standard error stream the list of hyphenation exceptions associated with the current hyphenation language. * A new request, `pline`, reports to the standard error stream the list of output nodes (an internal data structure) corresponding to the pending output line. The list is empty if no such nodes exist. * The `pm` request now interprets any arguments as a sequence of macro, string, or diversion names, and reports their contents. * The `pnr` request now additionally reports the autoincrementation amount and interpolation format of each register (if it is not string-valued). * The `pnr` request now accepts arguments. It treats each as identifying a register and reports its properties to the standard error stream. * A new request, `pstream`, reports to the standard error stream the name of each stream opened with the `open` or `opena` requests, the name of the file backing it, and its mode (writing or appending). * The `ptr` request has been renamed to `pwh` (mnemonic: "Print WHen traps will spring"). As a rule, debugging requests starting with `p` correspond to a request name that manipulates the objects reported on when the `p` is removed. However, `ptr` had nothing to do with the `tr` request. The only exceptions to the stated rule of `p`-removal are now `line`, `m`, and `stream`, none of which are request names. * The `hla` request, when invoked with no arguments, now clears the hyphenation language, disabling automatic hyphenation. * The read-only registers `.m` and `.M` now interpolate "default" when the default color is selected as the stroke or fill color, respectively, rather than interpolating nothing. * Numeric expression contexts that accept the `z` and `u` scaling units, such as the `ps` request and `\s` escape sequence, now also accept `p` and `s`. * troff's `-c` command-line option now also removes the `color` request's ability to enable multi-color output. eqn --- * The "gifont" primitive replaces "gfont" as the means of configuring the global italic face in preprocessed equations. "gfont" remains recognized as a synonym for backward compatibility. The new name is intended to ease acquisition of the eqn language in light of GNU eqn's thirty-year-old extensions "gbfont" and "grfont". * New parameters tunable with the GNU eqn "set" primitive, "half_space" and "full_space", enable a document to configure the space widths produced by the eqn tokens '^' and '~', respectively. Previously, their widths were determined by the "thin_space" and "thick_space" parameters used to tune GNU eqn's automatic spacing computations. * The new "reset" primitive restores a named parameter to its default. groff ----- * The groff command now encodes the fate of failing processes in the pipeline it constructs and runs so that this information cannot be confused with groff's own error conditions (such as a usage error, which now produces an exit status of 2). See the section "Exit status" of groff(1) for details. * groff now passes the -S option to pic and troff if it is specified. nroff ----- * nroff now recognizes the -a, -D, -I, and -Z options and passes them to groff. * nroff now supports clustered options ("-tzms", for example) as groff, troff, and other GNU getopt-using programs do. pic --- * A new command, `polygon`, supports drawing polygons using arbitrary vertices. The command furthermore accepts the `fill[ed]` modifier. You can address a polygon's vertices and the midpoints of its edges with the new `.v[er[tex]]` and `.mid[point]` syntax suffixed to an object identifier, analogously to the existing compass point and `.c[enter]` feature. Thanks to Duncan Losin. * pic's -S option now "locks" safer mode, rejecting any subsequent specification of -U on the command line with an error diagnostic. soelim ------ * soelim no longer requires embedded space characters in `so` arguments to be backslash-escaped. (It continues to support that syntax, even though neither the AT&T nor GNU troff formatters ever have.) You can now embed a sequence of leading spaces in the argument by prefixing it with a with a neutral double quote character ("), which the program discards. These changes are to better align this program's parsing rules with the language of the formatter; consider the `ds` and `as` requests. Macro packages -------------- * Keith Marshall's pdfmark package is no longer distributed with groff, but is now separately maintained. Please visit for the latest version. * mom version 2.6 is distributed with this release. It supports multi-line headings. Thanks to Peter Schaffter. * The device-specific macro files loaded by "troffrc" automatically on startup, such as "html.tmac", no longer perform font translations for some font names used by varieties of AT&T troff ('C', 'Hb', 'HX', and several others). These names are not portable: in AT&T troff, the font repertoire, like the special character repertoire, was device-dependent. Since groff 1.23.0, GNU troff diagnoses attempts to use nonexistent font names. We recommend addressing such portability issues wherever suits you: (1) in a document, perhaps by using `ie` and `el` requests and the `.g` register to test whether the formatter claims support for groff extensions, then `ie` and `el` again with the `F` groff conditional expression operator to check for font availability, and to perform font remappings with the groff `ftr` request as desired; (2) doing so in your "troffrc" file; or (3) by modifying these macro files similarly. Users of the "dvi" and "lbp" output devices should be aware that these devices don't supply full families of monospaced fonts (and never have). See grodvi(1) and grolbp(1) for lists of font names supported by each device. The legacy names are retained for the "pdf" and "ps" devices for this release; however, use of them prompts one warning in the "font" category from the formatter per deprecated name. We expect to withdraw support for the names completely in a future groff release. See gropdf(1) and grops(1) for lists of font names supported by each device. * Hyperlink support is now enabled by default on PDF and terminal devices for an (man) and doc (mdoc) documents. Instructions and commented code for disabling it are in the "man.local" and "mdoc.local" files. * The `PDFPIC` macro implemented in the "pdfpic.tmac" macro file now uses identify(1) (from ImageMagick/GraphicsMagick) and file(1), if available, to attempt to determine the dimensions of an image to be embedded in a PDF document. See also the item regarding gropdf(1) below. Thanks to Deri James. * The an (man) package now supports use of its hyperlink macros (`UR`, `UE`, `MT`, and `ME`) in paragraph tags (that is, on the next line after a `TP` macro call). Use of the `MR` man page cross reference macro in a tag was already supported in groff 1.23.0. * The behavior of the an (man) package's `SY` and `YS` macros has been expanded to enable greater user control over vertical spacing and to make them convenient for synopsizing C language functions, not just commands. `SY` no longer puts vertical space on the output, and initially breaks the output line _only_ if it is encountered repeatedly without a preceding `YS` call. The computed indentation of synopsis lines after the first now also includes the width of anything already on the output line, so that you can precede the `SY` call with, for instance, the C language data type used for the return value in a function prototype. The `SY` macro now accepts an optional second argument. This second argument is typeset in bold, replaces the fixed-width space that is appended to the synopsis keyword in `SY`'s single-argument form, and is used in computation of the indentation of non-initial synopsis lines. However, this computed indentation can now also be overridden with that of the previous synopsis item. To do this, give any argument to the `YS` macro call "closing" the synopsis whose indentation you want to reuse. When you're done with such a grouped synopsis, leave the argument off the final `YS` call. In a "Synopsis" section of a man page, existing synopses consisting of a single item require no migration. This is the most common case. For others, where before you would write... .SY mv .I source .I destination .YS . .SY mv .I source \&.\|.\|.\& .I destination-directory .YS ...you would now write the following. .SY mv .I source .I destination .YS . .P .SY mv .I source \&.\|.\|.\& .I destination-directory .YS (That is, simply add a paragraphing macro.) And where before you would write... .SY mv .B \-h . .SY mv .B \-\-help .YS ...you would now write the following. .SY mv .B \-h .YS . .SY mv .B \-\-help .YS (That is, simply add `YS` after the first synopsis item.) Likely the biggest benefit of these changes is that it is now much easier to format C function prototypes with these macros. Here's how we would synopsize a somewhat complex standard C library function. .B "#include " .P .B void *\c .SY bsearch ( .BI const\~void\~*\~ key , .BI const\~void\~*\~ base , .BI size_t\~ nmemb , .BI int\~(* compar )\c .B (const\~void\~*, const\~void\~*)); .YS * The an (man), doc (mdoc), and doc-old (mdoc-old) macro packages have changed the default line length when formatting on terminals from 78n to 80n. The latter is a vastly more common device configuration, but that line length had been avoided since the groff 1.18 release in July 2002 (prior to that, the line length was 65n, as in AT&T nroff), for an undocumented reason. That reason appears to have been the interaction of bugs in GNU tbl(1) with an aspect of grotty(1)'s design. Those bugs have been resolved. A man(1) program can still instruct groff to format for any desired line length by setting the `LL` register on {g,n,t}roff's command line. * The an (man) and doc (mdoc) macro packages use slightly different vertical margins than previously, to align more closely with the traditional implementations of these packages. Per man(7) in the AT&T Unix System III manual (June 1980), the text area was 6.5 by 10 inches (on typesetters). When formatting for terminals with continuous rendering disabled (by default, it is enabled), the page footer now sets one line higher than before. * The an (man) and doc (mdoc) macro packages have added additional registers `BP`, `PO`, and `TS` for user configuration of man page rendering at formatting time. As noted in groff_man(7) and groff_mdoc(7), documents should never manipulate these. * The an (man) and doc (mdoc) macro packages now support a `BP` register to configure the ("base") paragraph inset amount; that is the amount used by man(7) for paragraphs not within an `RS`/`RE` relative inset, and in mdoc(7) for all paragraphs. Formerly, the `IN` register configured this amount with other indentation and inset amount parameters used by man(7). (In mdoc(7), it had no other purpose.) The base paragraph indentation default is now 5n, corresponding to that used by historical man(7) and mdoc(7) implementations going back to Unix Version 7 (1979) and 4.3BSD-Reno (1990), respectively. * The an (man) and doc (mdoc) macro packages now support a `PO` register to configure the page offset used by the formatter. * The an (man) macro package now supports a `TS` register to configure the minimum space required between the tag of a `TP` paragraph and its body. (If the width of the tag's formatted text plus this space exceeds the paragraph indentation, the line is broken after the tag.) This parameter, formerly hard-coded as `1n`, now defaults to `2n`. * The an (man) macro package's `IP` macro no longer honors the formerly hard-coded 1n tag separation noted in the previous item. This means that the first argument to the `IP` macro can abut the text of the paragraph with no intervening space. If you use a word instead of punctuation or a list enumerator for `IP`'s first argument, consider migrating to `TP`. * The "an-ext.tmac" macro file, loaded automatically by the an (man) macro package, no longer defines `DS` and `DE` macros. It had defined them as empty (undocumentedly) since groff 1.20 (2009). * The doc (mdoc) macro package's `Mt` macro now sets its argument in roman, not italics (or whatever the string `doc-Pa-font` was configured to use). A new string, `doc-Mt-font`, for use in "mdoc.local" files and similar, supports configuration of this face. * The doc (mdoc) macro package now performs font family switches inline (that is, on the same output line) to Courier much less frequently when formatting for typesetters, affecting the `Ar`, `Cm`, `Er`, `Fa`, `Fd`, `Fl`, `Fn`, `Ft`, `Ic`, `Li`, and `Nm` macros. This change was made to reduce the ambiguity of space widths when typesetting the monospaced Courier and proportional Times fonts adjacently. Bear in mind that you can use the "mdoc.local" file to customize the font used to render nearly any mdoc(7) macro's arguments; this mechanism has been in place since 1992. * The doc (mdoc) macro package's `Ql` macro now operates more simply; it no longer (ever) quotes its arguments when formatting for typesetters. In practice, it does not seem difficult to distinguish even single characters in Courier from those in Times. (If it is, an _explicit_ quoting macro like `Sq` or `Dq` should be used.) * The doc (mdoc) macro package's `Lk`, `Mt`, and `Xr` macros now produce hyperlinks on HTML, PDF, and terminal devices. See above regarding hyperlink support being enabled by default. * The doc (mdoc) macro package now honors the `U` register and `MF` string as the an (man) package does. * The new macro file "koi8-r.tmac" supports the KOI8-R character encoding, which supports the new Russian locale for groff. * The m (mm) macro package now uses a 3v bottom margin rather than 2v. (Using the default type size and vertical spacing, the result is a half-inch margin, just like the existing top margin.) When formatting for terminals, content aligned to the bottom of the page (footers, footnotes, `BS`/`BE` bottom blocks, and similar) now sets one line higher than before. Further, the margin between the body text and any page footers is now 2v, like that between the body text and page headers, not 1v. * The m (mm) macro package's `Limsp` register (a GNU extension) has been removed; see the item regarding the `LI` macro below. * The m (mm) macro package's `Le` register now defaults to `1`, consistently with the `Lf`, `Lt`, and `Lx` registers of similar purpose, but inconsistently with DWB 3.3 mm. Explicitly assigning the `Le` register in a document's preamble works as it always has. * The m (mm) macro package's `AST` macro (a GNU extension) is deprecated, warns upon usage, and is slated for withdrawal in a future release. Assign to the new string `Abstract` instead. * The m (mm) macro package's `ISODATE` macro (a GNU extension) is deprecated, warns upon usage, and is slated for withdrawal in a future release. Assign to the new register `Isodate` instead. * The m (mm) macro package's `EPIC` macro (a GNU extension) now interprets its "width" argument in ens by default, and its "height" argument in vees, instead of basic units, for consistency with the rest of the package. * Similarly, the m (mm) macro package's `PIC` macro (a GNU extension) now interprets an argument to its `-I` option in ens instead of ems by default. * The m (mm) macro package no longer superscripts _and_ brackets a reference mark (the `Rf` string). Instead, the new `Rfstyle` register controls its formatting. The default, 0, selects bracketing in nroff mode and superscripting in troff mode. Set `Rfstyle` to 3 in a document to obtain groff mm's previous mark formatting behavior. * The m (mm) macro package's `Li` register now defaults to 5 ens (not 6) to align with the `Pi` register default. * The m (mm) macro package's `Li` register now configures the text indentation of items in `RL` lists (as it long has for `AL` lists) instead of hard-coding a value of 6 ens as DWB 3.3 mm does. * The m (mm) macro package's `BVL` (a GNU extension) and `VL` macros' first arguments are now optional. If omitted, the paragraph indentation amount (register `Pi`) is used for list items' text indentations. * The m (mm) macro package's `DL` macro now uses the `EM` string as the mark instead of an em dash special character literal. (The latter remains the default definition of the `EM` string.) * The m (mm) macro package's `DS` macro now interprets its third argument (a right-hand indentation) in ens by default, for consistency with the rest of the package. This is a difference from DWB mm (which passed the value unprocessed to the `ll` request, which itself uses ems), and groff mm's own historical behavior, which used basic units. * The m (mm) macro package's `HU` macro now supports an optional second argument as a GNU extension. It corresponds to the optional third argument of the `H` macro. * The m (mm) macro package's `IND` macro (a GNU extension), now calls `SK` only if no `TXIND` macro is defined, instead of performing this action as part of the fallback when no `TYIND` macro is defined. * The m (mm) macro package now supports a user-definable hook macro `AFX`, which if defined is called by `AF` in lieu of the latter's normal operation. Applications include customization of letterhead. * The m (mm) macro package now supports a user-definable hook macro `RPX`, which if defined is called by `RP` in lieu of the latter's normal operation (breaking the page [potentially], and formatting the reference list caption string `Rp`). * The m (mm) macro package's `LI` macro now interprets its second argument as a Boolean value indicating whether a space should separate the list item mark from its prefix (the first argument). Thus, where you formerly specified "2" to indicate no such separation, you would now use "0", matching the semantics of the former `Limsp` register. "2" continues to be recognized and handled as before, but prompts a warning; migrate your documents. * The m (mm) macro package now supports an `Aumt` string to suppress the appearance of positional arguments to the `AU` macro in the document heading used by memorandum types 0-3 and 6. By default, all such arguments appear, except the second (author initials). For example, a value of "3 4" more accurately reproduces London & Reiser's 1978 paper describing the porting of Unix to the VAX-11/780. * The m (mm) macro package now supports an `Rpfmt` string specifying the `LB` macro arguments that the package uses to format the items in an `RP` reference list. * The m (mm) macro package now supports the `E` register as DWB mm did. * The m (mm) macro package now supports DWB mm's `Rg` string. * The m (mm) macro package's `nP` macro now behaves more like DWB mm's. It applies a temporary indentation to the second output line of a paragraph to align it with the start of the paragraph text (not the tag/label) in the first, and resets the paragraph counter when the first- or second-level section heading number increments. * The m (mm) macro package's `Iso` register is now named `Isodate` to make its meaning less ambiguous. The old name remains as an alias. * The m (mm) macro package's `Rpe` register is now named `Rpej` for better symmetry with `Ej`. The old name remains as an alias. * The m (mm) macro package has renamed several strings to make their purposes less obscure; they determine the content of captions, not list items. `Licon` -> `Captc` `Liec` -> `Capec` `Liex` -> `Capex` `Lifg` -> `Capfg` `Litb` -> `Captb` The old names remain as aliases. * The m (mm) macro package has renamed the `Tcst` string to `Tcstatus` to make its purpose less obscure. The old name remains as an alias. * The m (mm) macro package recognizes new register names `Ftnum` and `Rfnum` for the automatically incrementing footnote and reference counters. The old, DWB-compatible but cryptic, names `:p` and `:R` remain supported. * The s (ms) macro package now sets the vertical spacing register defaults for normal (`VS`) and footnote (`FVS`) text to 120% of the type size configured in the `PS` and `FPS` registers, respectively, rather than 2 points larger, to comport with generally accepted typesetting principles. Thus, when formatting a document with a type size of 20 points, the vertical spacing now defaults to 24 points rather than 22. * The s (ms) macro package now subtracts one vee from the footer trap location computed using the `FM` register. When using the default `FM` value of `1i`, this makes the size of the margin from the footer baseline to the bottom of the page 3 vees or one half-inch, consistently with that between the header baseline and the page top. While a bug fix, and consistent with DWB 3.3 ms, this computation is inconsistent with Seventh Edition Unix ms and Heirloom Doctools ms. When formatting for terminals, footers now set one line higher than before. The size of the footnote area is not affected; instead there is a 1v smaller margin between its bottom and the footer baseline. Output drivers -------------- * grohtml(1), the (X)HTML output driver, supports a new `-k` command- line option that takes a mandatory argument, either "ascii" or "utf-8", which it recognizes case-insensitively. This feature configures representation of character entities in the output. Based on work by TANAKA Takuji. * gropdf(1), the PDF output driver, now allows embedding of JFIF/JPEG and JPEG 2000 image file formats. If PerlMagick is installed, many more image file formats, including PNG, PAM, and GIF, can be embedded. See also the item regarding `PDFPIC` above. Thanks to Deri James. * gropdf now supplies its own "SS" (slanted symbol) font to improve rendering of documents requiring slanted lowercase Greek letters, such as those employing the eqn(1) preprocessor. groff supplies the font in PFB format, and gropdf automatically embeds it, as it is not a standard PDF font. Formerly, groff's "pdf.tmac" file defined fallback characters for lowercase Greek letters, applying a slant of 16 degrees to the upright glyphs available in the standard symbol font "S". That technique produced glyphs slightly larger than those in grops's "SS" font. Thanks to Deri James. * gropdf now subsets embedded fonts by default, meaning that it stores only the glyphs a document actually uses. Font subsetting usually reduces the size of the PDF gropdf creates. Thanks to Deri James. * gropdf supports a new `--opt` command-line option, permitting a few features, including font subsetting, to be selectively enabled. Thanks to Deri James. * gropdf now emits PDFs that conform to the PDF 1.7 standard (also known as ISO 32000). Its new `--pdfver` command-line option permits production of PDF 1.4-conformant output instead. Thanks to Deri James. * gropdf supports a new `pdf: pagenumbering` device extension command and `pdfpagenumbering` convenience macro, allowing control of the page numbers in a PDF reader's overview panel. It is common for a document to number early pages with Roman numerals and then restart page enumeration at decimal 1 for its main matter. Thanks to Deri James. * gropdf now offers its own implementations of the "pdfmark" macro package's "pdfhref" and other macros, supporting internal (bookmarks, named destinations) and external (URL) hyperlinks, and the specification of hotspots for link text. For example, when bundling multiple man pages into a collection, as the supplied groff-man-pages.pdf document and the Linux man-pages project do, references to man pages within the collection are supported with internal hyperlinks, and those outside with external ones. Thanks to Deri James. * gropdf now supports characters outside the Unicode Basic Latin subset in bookmarks, named destinations, and external hyperlinks. (They must be encoded using groff's Unicode special character escape sequences; the preconv preprocessor is helpful to simply this requirement.) Thanks to Deri James. * gropdf now recognizes a `GROPDF_OPTIONS` environment variable, interpreting it as a space-separated list of command-line options. Explicit command-line options override any settings from this environment variable. You can use this variable to obviate passing options to gropdf via groff's `-P` option. Thanks to Deri James. * grops(1), the PostScript output driver, now supports fonts encoded using UTF-16. Indicate the encoding by including the string "-UTF16-" within the font's name as specified by the "internalname" directive in its font description file. Thanks to TANAKA Takuji. * The PostScript output driver grops(1) no longer accepts spaces as field separators in its "download" file; this is so that spaces can appear in font file names, and to better align the syntax of this file with that used by gropdf(1). The download file for grops shipped by groff has long used tabs rather than spaces for field separation. * The PostScript output driver grops(1)'s macro file "ps.tmac" no longer defines fallback special characters `\[S ,]` and `\[S ,]` to simulate support for what Unicode calls LATIN {CAPITAL,SMALL} LETTER S WITH COMMA BELOW. The file's definition constructed these glyphs by overstriking the Basic Latin "S" (or "s") with a cedilla accent, which is regarded as less orthographically acceptable than in the past. A user's document or macro file can still do exactly what "ps.tmac" used to. .fchar \[S ,] \o'S\[ac]' .hcode \[S ,]s .fchar \[s ,] \o's\[ac]' .hcode \[s ,]s * The PostScript output driver grops(1) once again accepts a file name containing slashes as a document prolog or resource (such as a font to be downloaded into the document). This is a restoration of groff 1.22.4 and earlier behavior; groff's 1.23.0 change of not accepting a file name containing slashes as an encoding or font description remains in place. (We impose this restriction because the output driver interprets the contents of these files; it does not interpret the PostScript prolog or resource files.) * grotty(1) now supports devices recognizing ECMA-48/ISO 6429 SGR 38 and 48 escape sequences that select RGB colors using 8 bits per color channel. A new command-line option, `-t`, configures emission of these escape sequences instead of the SGR 30-37 and 40-47 sequences supporting 3- or 4-bit color. Thanks to Deri James. Example: $ groff -T utf8 -P -t <s. * The localization macro files now set up an appropriate hyphenation mode default. For Chinese and Japanese, this is zero. * If groff programs have their current time overridden by the SOURCE_DATE_EPOCH environment variable, then that time is always displayed in UTC. That environment variable is normally only set when specifically requesting build systems to produce reproducible output, and it is useful for reproducibility test harnesses to vary the TZ environment variable and ensure that it does not affect the output of the build; those harnesses have no way to set TZ=UTC only for groff programs. People setting SOURCE_DATE_EPOCH are likely to be more in the "system programmer" camp as described in the release notes for 1.23.0, so it is easier to defend time-zone-invariant output to them. In all other cases, the current time remains displayed in local time. Thanks to Colin Watson. * The minimum version of Perl required to build groff is now 5.8 (18 July 2002), incremented from 5.6.1. * groff now looks for the Netpbm program pamcut(1) rather than pnmcut(1). Per its developers, the former was introduced in 2001 ago and the latter withdrawn in 2009. * The Makefile macro `DEVICE` has been renamed to `DEFAULT_DEVICE`; be aware if your builds don't use "ps" as the default output device. * The groff_diff(7) man page no longer contains examples. They remain in groff's Texinfo manual. * groff's Texinfo manual now adapts its content to the groff command prefix configured at build time. If the build is configured without a leading "g"--omitting it has been groff's default for many years, possibly forever--then our Texinfo manual now omits that prefix when mentioning the affected commands (all replacements for AT&T troff commands). This way, if you select a command prefix, say "limbo", and rebuild the Texinfo manual, the manual reflects the prefix used by your build configuration, and talks about "limboeqn", "limbotroff", "limborefer", and so on. @ text @$NetBSD: patch-aa,v 1.8 2025/01/29 10:31:53 jperkin Exp $ Fix path to papers directory on NetBSD.

Value 16 enables hyphenation before the last character, and value 32 enables hyphenation after the first character. PDFPIC ------ o PDFPIC has been corrected so the behaviour is the same whether you use the PostScript or PDF drivers. However, this means that any documents which were written using the old behaviour will not be rendered correctly if using the PDF driver with the new version. The change would mean that documents which relied on the previous behaviour are likely to have a gap underneath the image which was not there before. If you see this effect there are three ways you can restore the previous behaviour: Add the line ".nr PDFPIC_NOSPACE 1" to the document before the first call to .PDFPIC. If it is just a single document which exhibits this behaviour you can run groff adding "-rPDFPIC_NOSPACE=1" to the command line. If you have many documents which rely on the previous behaviour you can set an environment variable "export GROFF_PDFPIC_NOSPACE=1" which will restore the previous behaviour for all runs. Note that this change has no effect if you were using .PDFPIC with the PostScript driver--only if you used it with the PDF driver. Gropdf ------ o Type 1 font loading is fixed to handle newer Ghostscript versions. o Handling of glyphs above position 255 is improved to allow many more glyphs to be used. o New macros .pdftransition and .pdfpause are introduced to allow creation of presentation slides. Partially backward-compatible with present.tmac, specifically the PAUSE, BLOCKS and BLOCKE commands. Supports all the transition types introduced in PDF v1.5 (see the gropdf man page). Miscellaneous ------------- o A new 'configure' option --with-compatibility-wrappers controls how groff compatibility wrappers for vendor-provided non-GNU macro sets are installed (see ./configure --help). o eqn2graph, grap2graph, and pic2graph now attempt to adapt to very old installed versions of the ImageMagick and GraphicsMagick programs "convert". They search the output of convert's "-help" option, and use "-trim" if that string is found; otherwise, the old "-crop 0x0" method (which produces incompatible results on versions that _do_ support "-trim") is used. The programs emit a warning to standard error if the search fails and the old method is used. o eqn2graph no longer supports the "-unsafe" option. It did nothing. o groffer now supports the output of XHTML. Use the "--xhtml" or "--mode=xhtml" command-line options to generate it. o Much work has been done, and is ongoing, to make groff's man pages better examples for man page writers to follow. groff_man(7) itself has been expanded and largely rewritten to more precisely document the macro package's behavior and to be more helpful and accessible to man page writers who may never read any other groff documentation. @ text @d1 1 a1 1 $NetBSD: patch-aa,v 1.6 2015/10/15 14:11:20 richard Exp $ d6 1 d8 1 a8 1 --- Makefile.in.orig 2018-12-23 14:34:27.000000000 +0000 d10 1 a10 1 @@@@ -3681,7 +3681,7 @@@@ tmac_an_prefix = \ d19 9 @ 1.6 log @Avoid arbitrary decisions wrt troff being present or not to use a g'prefix.

VERSION 1.19.2 ============== Troff ----- o Analogously to the .ft and \f pair, two new requests `gcolor' and `fcolor' (which pair with \m and \M, respectively) have been added to set the glyph and background colours. o A new read-only, string-valued register `.sty' returns the name of the current style. o Two new conditional operators `F ' and `S ' have been added. `F' is true if a font exists. `S' is true if a style has been registered. o Cyrillic characters have been added to the `utf8' and `html' output devices. Pic --- o The `by' argument in a `for' loop can now be negative if it is additive. For the multiplicative case, it must be greater than zero. Eqn --- o The following keywords aren't new but haven't been documented previously: undef NAME (to undefine a macro) copy "FILE" (a synonym for `include') space n (to modify the vertical spacing before and after an equation) o The following macros aren't new but haven't been documented previously: Alpha, ..., Omega (the same as `ALPHA', ..., `OMEGA') ldots (three dots on the base line) dollar (a dollar glyph) o The following keywords have been extended.

Grotty ------ o Experimental support for zero-width and double-width characters. Gxditview --------- o On platforms which have the X Window System this program is now built and installed automatically. Xtotroff -------- o This program to create font definition files for xditview isn't new but hasn't been installed previously. Groffer ------- o A security problem (reported as CAN-2004-0969) has been fixed. Gdiffmk ------- o A new script contributed by Mike Bianchi. It compares two groff, nroff, or troff documents and creates an output with added margin characters (using `.mc') to indicate the differences. Pdfroff ------- o A new wrapper script contributed by Keith Marshall to easily create PDF documents with groff. Macro packages -------------- o ms.tmac . Support for fractional point sizes: A value for the `PS', `VS', `FPS', and `VPS' register larger than or equal to 1000 is always divided by 1000. For example, `.nr PS 10250' sets the document's font size to 10.25 points. . The `Ds' and `De' macros provided in ms since groff version 1.19 have been removed; the equivalent `DS' and `DE' macros should be used instead. X11 documents which actually use `Ds' and `De' always load a specific macro file from the X11 distribution (`macros.t') which provides proper definitions for the two macros. . The following registers have been added for improving layout control: PORPHANS Defines number of lines following `LP', `PP', `QP', `IP' or `XP' which must be kept together, before any automatic page break. HORPHANS Sets number of lines of following paragraph which must be kept with a heading, defined by `NH' or `SH', before any automatic page break. GROWPS Sets the first level of heading (set with `NH') which will keep the same point size as body text. PSINCR Sets the point size increment for each level of heading (set with `NH'), below the threshold level set by `GROWPS'; e.g., if \n[PS] = 10, \n[GROWPS] = 3 and \n[PSINCR] = 2.0p, then `.NH 1' will produce 14pt headings, `.NH 2' will produce 12pt, and all other levels will remain at 10pt (because \n[PS] = 10). . The `SH' macro now accepts a numeric argument, to make heading size match that of `NH' with same argument value when the `GROWPS'/`PSINCR' feature is enabled. Please refer to the documentation of the ms package for other, minor improvements. o me.tmac The section type set with the `++' request is available in the `_M' register. This isn't new but hasn't been documented before. o www.tmac The `HR' macro no longer causes an empty line for non-HTML devices. A new macro `HEAD' has been added to directly add data to the ... block. New macros `OLS' and `OLE' to start and end an ordered list. New macros `DLS' and `DLE' to start and end a definition list. Pdfmark ------- o A new macro package contributed by Keith Marshall which implements PDF marks. This is in alpha stage currently. Miscellaneous ------------- o Two new keywords to the DESC file have been added which are needed for grohtml: `image_generator' and `unscaled_charwidths'. The former gives the name of the program which creates PNG images, and the latter makes troff always use unscaled character widths. @ text @d1 3 a3 1 $NetBSD: patch-aa,v 1.3 2004/07/11 13:40:06 wiz Exp $ @ 1.3 log @Update to 1.19.1: Groff ----- o The argument of the command line option `-I' is now also passed to troff and grops, specifying a directory to search for files on the command line, files named in `so' and `psbb' requests, and files named in \X'ps: file' and \X'ps: import' escapes. o If option `-V' is used more than once, the commands will be both printed on standard error and run. Troff ----- o Two new read-only, string-valued registers `.m' and `.M' return the name of the current drawing and background color, respectively. o New read-only register `.U' which is set to 1 if in safer mode and set to 0 if in unsafe mode. o An input encoding file for latin-5 (a.k.a. ISO 8859-9) has been added. Example use: groff -Tdvi -mlatin5 my_file > my_file.dvi Note that some output devices don't support all glyphs of this encoding. o If the `return' request is called with an argument, it exits twice, namely the current macro and the macro one level higher. This is used to define a wrapper macro for `return' in trace.tmac. o For completeness, two new requests have been added: `dei1' and `ami1'. They are equivalent to `dei' and `ami', respectively, but the macros are executed with compatibility mode off (similar to `de1' and `am1'). o New command line option `-I' to specify a directory for files (both those on the command line and those named in `psbb' requests). This is also handled by the groff wrapper program. o Since version 1.19 you can say `.vs 0'. Older versions emit a warning and convert this to `.vs \n[.V]'. This hasn't been documented properly. Note that `.vs 0' isn't saved in a diversion since it doesn't result in vertical motion. Pic ___ o Dashed and dotted ellipses have been implemented. Tbl --- o New key character `x' to make tbl call a user-defined macro on a table cell. Patch by Heinz-Jürgen Oertel . Grap2graph ---------- o A new script contributed by Eric S. Raymond . It converts a grap diagram into a cropped image. Since it uses gs and the PNM library, virtually all graphics formats are available for output. [Note that the grap program itself isn't part of the groff package; see the file MORE.STUFF how to obtain grap.] Grohtml ------- o New option `-j' to emit output splitted into multiple files. Grops ----- o New command line option `-I' to specify a directory to search for files on the command line and files named in \X'ps: import' and \X'ps: file' escapes. This is also handled by the groff wrapper program. o The default value for the `broken' keyword in the DESC file is now 0. Grolj4 ------ o A new man page `lj4_font(5)' documents how fonts are accessed with grolj4. o The built-in fonts for LJ4 and newer PCL 5 devices have been completely revised, mainly to access as much glyphs as possible. The provided metric files should be compatible with recent PCL 5 printers also. Additionally, font description files have been added for the Arial and Times New Roman family, the MS symbol, and Wingdings fonts. Afmtodit -------- o New option `-x' to prevent use of built-in Adobe Glyph List. Hpftodit -------- o Completely revised to handle HP TrueType metric files also. See the hpftodit manual page for more details. Groffer ------- o This version is a rewrite of groffer in many parts, but it is kept in the old single script style. New options: --text, --mode text, --tty-viewer, --X, --mode X, --X-viewer, --html, --mode html, --html-view, --apropos-data, --apropos-devel, --apropos-progs. New documentation file: README_SH. Enhancement of the configuration files and the `apropos' handling. Macro Packages -------------- o www.tmac: New macro `JOBNAME' to split output into multiple files. o In mdoc, multiple calls to `.Lb' are now supported in the LIBRARY section. @ text @d1 1 a1 1 $NetBSD$ d3 1 a3 1 --- Makefile.in.orig 2004-04-07 17:33:39.000000000 +0200 d5 1 a5 1 @@@@ -186,7 +186,7 @@@@ tmac_an_prefix=\ @ 1.2 log @Update to 1.18.1. [XXX: Solaris PLIST needs merging/update] Changes since 1.16.1: [If you don't read all of them, please note at least that you will have to use less's -R option to view man pages, like ``${PREFIX}/bin/nroff -mdoc somemanpage.1 | less -R'' .] VERSION 1.18.1 ============== Troff ----- o The non-slanted PostScript font definition files have been regenerated to include left and right italic correction values. Applying those to a glyph (this is, prepending the glyph with `\,' and appending `\/' to the glyph) sets the glyph width to the real value given by the horizontal bounding box values. Without those escapes, the advance width for the particular glyph is used (which can differ considerably). Most users will neither need this feature nor notice a difference in existing documents (provided \, and \/ is used as advertised, namely for italic fonts only); its main goal is to improve image generation with grohtml. This is an experimental change, and feedback is welcome. Tbl --- o Added global option `nospaces' to ignore leading and trailing spaces in data items. Grolbp ------ o The option -w (--linewidth) has been added (similar to other device drivers) to set the default line width. Grn --- o Support for b-spline and Bezier curves has been added. Groffer ------- o New option `--shell' to select the shell under which groffer shall run. Macro Packages -------------- o The string `Am' (producing an ampersand) has been added to mdoc for compatibility with NetBSD. o `.IX' is now deprecated for mom; you should use `.IQ' (Indent Quit) instead. o In mom, new inlines `FWD', `BCK', `UP', and `DOWN' deal with horizontal and vertical movements; please refer to contrib/mom/NEWS for more details. o New macro ENDNOTES_HDRFTR_CENTER for mom to better control headers. Miscellaneous ------------- o The `papersize' keyword in the DESC file now accepts multiple arguments. It is scanned from left to the right, and the first valid argument is used. This makes it possible to provide a fallback paper size. Example: papersize /etc/papersize a4 o A local font directory has been prepended to the default font path; it defaults to /usr/local/share/groff/site-font. Similar to the normal font searching process, files must be placed into a devXXX subdirectory, e.g. /usr/local/share/groff/site-font/devps/FOO for a PostScript font definition file FOO. VERSION 1.18 ============ *************************************************************************** * * * PLEASE READ THE CHANGES BELOW REGARDING GROTTY, GROFF'S TTY FRONTEND. * * * *************************************************************************** Troff ----- o Color support has been added to troff and pic (and to the device drivers grops, grodvi, grotty, and grohtml -- other preprocessors and drivers will follow). A new function `defcolor' defines colors; the escape sequence `\m' sets the drawing color, the escape sequence `\M' specifies the background color for closed objects created with \D'...' commands. `\m[]' and `\M[]' switch back to the previous color. `\m' and `\M' correspond to the new troff output command sets starting with `m' and `DF'. The device-specific default color is called `default' and can't be redefined. Use the `color' request to toggle the usage of colors (default is on); the read-only register `.color' is 0 if colors are not active, and non-zero otherwise. The old `Df' output command is mapped onto `DFg'; all color output commands don't change the current font position (consequently, `Df' doesn't either). Outputting color can be disabled in troff and groff with the option -c (it is always disabled in compatibility mode). See the section on grotty for the GROFF_NO_SGR environment variable also. For defining color components as fractions between 0 and 1, a new scaling indicator `f' has been introduced: 1f = 65536u. For testing whether a color is defined (with .if and .ie), a new conditional operator `m' is available. More details can be found in the groff_diff.7 manual page and in groff.texinfo. o Similar to \m and \M, \f[] switches back to the previous font. \fP (and \f[P]) is still valid for backwards compatibility. o The new escape \F is the same as `.fam'; \F[] switches back to previous family -- \F[P] selects family `P'. o Two new glyph symbols are available: `eu' is the official Euro symbol; `Eu' is a font-specific glyph variant. o The new glyph symbols `t+-', `tdi', and `tmu' are textual variants of `+-', `di', and `mu', respectively. o Latin-1 character 181 (PS name `mu', Unicode name U+00B5 MICRO SIGN) has got the troff glyph name `mc'. o -Tutf8 is now available on EBCDIC hosts. o Strings can take arguments, using this syntax: \*[foo arg1 arg2 ...]. Example: .ds xxx This is a \\$1 test. \*[xxx nice] o It is now possible to have whitespace between the first and second dot (or the name of the ending macro) to end a macro definition. Example: .de ! .. . .de foo . nop Hello, I'm `foo'. . nop I will now define `bar'. . de bar ! . nop Hello, I'm `bar'. . ! .. o `.fn' is a new string-valued register which returns the (internal) real font name; styles and families are properly concatenated. o Three new read/write registers `seconds', `minutes', and `hours' contain the current time, set at start-up of troff. Use the `af' request to control their output format. o The new request `fchar' can be used to provide fallback characters. It has the same syntax as the `char' request; the only difference is that a character defined with `.char' hides the glyph with the same name in the current font, whereas a character defined with `.fchar' is checked only if the particular glyph isn't found in the current font. This test happens before checking special fonts. o In analogy to the `tmc' request, `.writec' is the same as `.write' but doesn't emit a final newline. o The new request `itc' is a variant of `.it' for which a line interrupted with \c counts as one input line. o Two new requests `ds1' and `as1' which are similar to `ds' and `as' but with compatibility mode disabled during expansion of strings defined by them. o The syntax of the `substring' request has been changed: The first character in a string now has index 0, the last character has index -1. Note that this is an incompatible change. o To emit strings directly to the intermediate output, a new `output' request has been added; it is similar to `\!' used at the top level. o `.hpf' has been extended. It can now handle most TeX hyphenation pattern files without modification. To do that, the commands \patterns, \hyphenation, and \endinput are recognized. Please refer to groff_diff.7 for more information. o `hpfcode' is a new request to provide an input encoding mapping for the `hpf' request. o The new request `hpfa' appends hyphenation patterns (`hpf' replaces already existing patterns). o A new request `ami' (append macro indirect) has been added. The first and second parameter of `ami' are taken from string registers rather than directly; this very special request is needed to make `trace.tmac' independent from the escape character (which might even be disabled). o The new request `sizes' is similar to the `sizes' command in DESC files. It expects the same syntax; the data must be on a single line, and the final `0' can be omitted. o `trin' (translate input) is a new request which is similar to `tr' with the exception that the `asciify' request will use the character code (if any) before the character translation. Example: .trin ax .di xxx a .br .di .xxx .trin aa .asciify xxx .xxx The result is `x a'. Using `tr', the result would be `x x'. o The request `pvs' isn't new, but hasn't been documented before. It adds vertical space after a line has been output. This makes it an alternative to the `ls' request to produce double-spaced documents. The read-only register `.pvs' holds the current amount of the post-vertical line space. o For compatibility with plan 9's troff, multiple `pi' requests are supported: .pi foo .pi bar is now equivalent to .pi foo | bar o A new escape sequence `\O' is available to disable and enable glyph output. Please see groff_diff.7 and groff.texinfo for more details. o The escapes `\%', `\&', `\)', and `\:' no longer cause an error in \X; they are ignored now. Additionally `\ ' and `\~' are converted to single space characters. o The default tab distance in nroff mode is now 0.8i to be compatible with UNIX troff. o Using the latin-1 input character 0xAD (soft hyphen) for the `shc' request was a bad idea. Instead, it is now translated to `\%', and the default hyphenation character is again \[hy]. Note that the glyph \[shc] is not useful for typographic purposes; it only exists to have glyph names for all latin-1 characters. Macro Packages -------------- o Peter Schaffter has contributed a new major macro package called `mom', mainly for non-scientific writers, which takes care of many typographic issues. It comes with a complete reference (in HTML format) and some examples. `mom' has been designed to format documents for PostScript output only. o Two macros `AT' (AT&T) and `UC' (Univ. of California) have been added to the man macros for compatibility with older BSD releases. o Both the man and mdoc macro packages now use the LL and LT registers for setting the line and title length, respectively (similar to those registers in the ms macro package). If not set on the command line or in a macro file loaded before the macro package itself, they default to 78n in nroff mode and 6.5i in troff mode. o The `-xwidth' specifier in the mdoc macro package has been removed. Its functionality is now integrated directly into `-width'. Similarly, `-column' has been extended to provide this functionality also. o A new macro `Ex' has been added to the mdoc macro package to document an exit status. o The PSPIC macro has been extended to work with DVI output (`pspic.tmac' is now automatically loaded for -Tdvi), using a dvips special to load the EPS file. o The trace.tmac package now traces calls to `am' also. Additionally, it works in compatibility mode. o `troff.1' has been split. Differences to UNIX troff are now documented in the new man page `groff_diff.7'. o `groff_mwww.7' has been renamed to `groff_www.7'. The file mwww.tmac has been removed. o `groff_ms.7' has been completely rewritten. It now contains a complete reference to the ms macros. o `groff_trace.7' documents the trace macro package. o Changes in www.tmac: Note that HTML support is still in alpha change, so it is rather likely that both macro names and macro syntax will change. Some of the macros mentioned below aren't really new but haven't been documented properly before. The following macros have been renamed: MAILTO -> MTO IMAGE -> IMG LINE -> HR For consistency, the macros `URL', `FTL', and `MTO' now all have the address as the first parameter followed by the description. By default, grohtml generates links to all section headings at the top of the document. Use the new `LK' macro to specify a different place. For specifying the background color and a background image, use the new macros `BCL' and `BGIMG', respectively. The macro `NHR' has been added; it suppresses the generation of top and bottom rules which grohtml emits by default. The new macro `HX' determines the cut-off point for automatic link generation to headings. The image position parameter names in `IMG' have been changed to `-L', `-R', and `-C'. New macro `PIMG' for inclusion of a PNG image (it will automatically convert it into an EPS file if not -Thtml is used). New macro `MPIMG' for putting a PNG image into the left or right margin (it will automatically convert it into an EPS file if not -Thtml is used). New macros `HnS', `HnE' to start and end a header line block. New macro `DC' to produce dropcap characters. New macro `HTL' to generate an HTML title line only but no H1 heading. New macros `ULS' and `ULE' to start and end an unordered list. The new macro `LI' inserts a list item. Groff ----- o The new command line option `-c' disables color output (which is always disabled in compatibility mode). Nroff ----- o Two new command line options `-c' and `-C'; the former passes `-c' to grotty (switching to the old output scheme); the latter passes `-C' to groff (enabling compatibility mode). Pic --- o New keywords `color' (or `colour', `colored', `coloured'), `outline' (or `outlined'), and `shaded' are available. `outline' sets the color of the outline, `shaded' the fill color, and `color' sets both. Example: circle shaded "green" outline "black" ; Filled arrows always use the outline color for filling. Color support for TeX output is not implemented yet. Pic2graph --------- o A new script contributed by Eric S. Raymond . It converts a PIC diagram into a cropped image. Since it uses gs and the PNM library, virtually all graphics formats are available for output. Eqn2graph --------- o A new script contributed by Eric S. Raymond . It converts an EQN diagram into a cropped image. Since it uses gs and the PNM library, virtually all graphics formats are available for output. Groffer ------- o A new script contributed by Bernd Warken . It displays groff files and man pages on X and tty, taking care of most parameters automatically. Grog ---- o Documents using the mom macro package are recognized. Grops ----- o Color support has been added. o A new option `-p' is available to select the output paper size. It has the same syntax as the new `papersize' keyword in the DESC file. Grodvi ------ o By default, font sizes are now available in the range 5-10000pt, similar to PS fonts. If you want the old behaviour (i.e., font sizes at discrete values only), insert the following at the start of your document: .if '\*[.T]'dvi' \ . sizes 500 600 700 800 900 1000 1095 1200 1400 1440 1600 \ 1728 1800 2000 2074 2200 2400 2488 2800 3600 o A new font file HBI (using cmssbxo10; this is slanted sans serif bold extended) has been added. o Two font families are now available: `T' and `H'. o EC and TC fonts have been integrated. Use `-mec' (calling the file ec.tmac) to switch to them. Those fonts give a much better coverage of the symbols defined by groff than the CM fonts. Note that ec.tmac must be called before any language-specific files; it doesn't take care of hcode values. o Color support has been added. For drawing commands, colors are translated to gray values currently. Grotty ------ o Color support has been added, using the SGR (ISO 6429, sometimes called ANSI color) escape sequences. o SGR escape sequences are now used by default for underlining and bold printing also, no longer using the backspace character trick. To revert to the old behaviour, use the `-c' switch. Note that you have to use the `-R' option of `less' to make SGR escapes display correctly. On the other hand, terminal programs and consoles like `xterm' which support SGR sequences natively can directly display the output of grotty. Consequently, the options `-b', `-B', `-u', and `-U' work only in combination with `-c' and are ignored silently otherwise. For the `man' program, it may be necessary to add the `-R' option of `less' to the $PAGER environment variable; alternatively, you can use `man's `-P' option (or adapt its configuration file accordingly). See man(1) for more details. o If the environment variable GROFF_NO_SGR is set, SGR output is disabled, reverting to the old behaviour. o A new special \X'tty: sgr n' has been added; if n is non-zero or missing, enable SGR output (the default). o If the new option `-i' is used (only in SGR mode), grotty sends escape sequences to set the italic font attribute instead of the underline attribute for italic fonts. Note that many terminals don't have support for this (including xterm). Grohtml ------- o Color support for glyphs has been added. o New option `-h' to select the style of headings in HTML output. o New option `-b' to set the background colour to white. o New options `-a' and `-g' to control the number of bits for anti-aliasing used for text and graphics, respectively. Default value is 4; 0 means no anti-aliasing. o groff character/glyph entities now map onto HTML 4 character entities. Grolbp ------ o Valid paper sizes are now specified as with the new `papersize' keyword in the DESC file. Specifically, the old custom paper type format `custAAAxBBB' is no longer supported. Miscellaneous ------------- o A new manual page `ditroff.7' is available. o The groff texinfo manual will now be installed, together with a bunch of examples. o A new keyword `papersize' has been added to the DESC file format. Its argument is either . a predefined paper format (e.g. `A4' or `letter') . a file name pointing to a file which must contain a paper size specification in its first line (e.g. `/etc/papersize') . a custom paper size definition like `35c,4i' See groff_font(5) for more details. This keyword only affects the physical dimensions of the output medium; grops, grolj4, and grolbp use it currently. troff completely ignores it. VERSION 1.17.2 ============== This is major bug-fixing release which should replace 1.17.1. Troff ----- o The `IMAGE' macro in www.tmac has changed: Now the optional 2nd parameter gives the horizontal image location (left, centered, or right), and the optional 3rd and 4th parameter the image dimensions. VERSION 1.17.1 ============== This is mainly a bug-fixing release. Troff ----- o Two new requests `de1' and `am1' which are similar to `de' and `am' but with compatibility mode disabled during expansion of macros defined by them. o Added request `brp'. This is the same as `\p'. o Similar to other versions of troff, the `ns' request now works in all diversions, not only in the top-level one. o New read-only number register `.ns'. Returns 1 if in no-space mode, 0 otherwise. Nroff ----- o Options -p (pic) and -t (tbl) added. o The environment variable GROFF_BIN_PATH is now checked before PATH for finding groff. Grohtml ------- o New option `-D dir' to specify a directory in which all images are placed. o New option `-I stem' to specify an image name stame. If not given, `grohtml-XXX' is used (`XXX' is the process ID). VERSION 1.17 ============ Groff ----- o `-mFOO' now searches first for `FOO.tmac' and then for `tmac.FOO'. The old behaviour has been changed to overcome problems with platforms which have an 8+3 file name limit, and platforms which have other versions of troff installed also. Additionally, all macro files have been renamed using the latter scheme to avoid 8+3 name clashes. o The new environment variable GROFF_BIN_PATH is checked for programs groff is calling (preprocessors, troff, and output devices) before PATH. If not set, it defaults to the directory where the groff binary is located. Previously, it was PATH only. The nroff script only uses GROFF_BIN_PATH to find the groff binary but passes both the GROFF_BIN_PATH and PATH environment variables to groff. Troff ----- o The mdoc package has been completely rewritten, using the full power of GNU troff to remove limitations of Unix troff (which is no longer supported). Most important changes are: . No argument limit . Almost all macros are parsed and callable (if it makes sense) . `.Lb': prints library names . `.Nm ' now works as expected; `.Nm "" ' has been withdrawn . Updated `.St' command . `.Fx': prints FreeBSD . `.Ox': prints OpenBSD . `.Bsx': prints BSD/OS . `.Brq', `.Bro', `.Brc': brace enclosure macros . `.Bd -centered': center lines . `.Bl -xwidth ': interpret and use the resulting width . Support for double-sided printing (-rD1 command line switch) . Support for 11pt and 12pt document sizes (-rS11, -rS12 command line switches) `groff_mdoc.7' replaces `groff_mdoc.samples.7'; it now completely documents the mdoc package. Great care has been taken to assure backwards compatibility. If you encounter any abnormal results, please report them to bug-groff@@gnu.org. o A new command line option for the `man' macros (similar to the `mdoc' package) has been implemented: `-rcR=1' (now the default in nroff mode) produces one single, very long page instead of multiple pages. `-rcR=0' deactivates it. o The `return' request has been added to return immediately from a macro. o A new request `nop' (no operation) has been added which is similar to `if 1'. For example, .if t \{\ Hallo! .\} can now be written as .if t \{\ . nop Hallo! .\} o `box' and `boxa' are two new requests which behave similarly to `di' and `da' but don't include a partially filled line (which is restored after ending the diversion). o The `asciify' request has been extended to `unformat' space characters and some other escape sequences also. `\ ' is no longer unformatted as a space but remains an unpaddable, unbreakable space character. o The new `unformat' request is similar to `asciify' but only handles space characters and tabs specially if the diversion is reread, retaining font information. This makes it possible to reformat diversions; for example the following .ll 3i . a01 a02 a03 a04 a05 a06 a07 a08 a09 a10. . .box box1 .ev 1 .nf \f[B]b01 b02 b03 b04 b05 b06 b07 b08 b09 b10.\f[P] .br .ev .box . c01 c02 c03 c04 c05 c06 c07 c08 c09 c10. . .unformat box1 .box1 gives a01 a02 a03 a04 a05 a06 a07 a08 a09 a10. c01 c02 c03 c04 c05 c06 c07 c08 c09 c10. b01 b02 b03 b04 b05 b06 b07 b08 b09 b10. Without the `unformat' request, space characters are converted to word space nodes which are no longer stretchable, and the result would be a01 a02 a03 a04 a05 a06 a07 a08 a09 a10. c01 c02 c03 c04 c05 c06 c07 c08 c09 c10. b01 b02 b03 b04 b05 b06 b07 b08 b09 b10. o The new request `linetabs' controls the `line-tabs' mode. In line-tabs mode, tab distances are computed relative to the (current) output line. Otherwise they are taken relative to the input line. For example, the following .ds x a\t\c .ds y b\t\c .ds z c .ta 1i 3i \*x \*y \*z yields a b c In line-tabs mode, the same code gives a b c The new read-only number register `.linetabs' returns 1 if in line-tabs mode, and 0 otherwise. o Two new requests `tm1' and `tmc' have been added to improve writing messages to the terminal. `tm1' is similar to `tm' but allows leading whitespace. `tmc' is similar to `tm1' but doesn't emit a final newline. o For compatibility with sqtroff, the request `output' has been added. The behaviour is similar to `\!' at the top-level, that is, it directly inserts its argument into the intermediate output format. The syntax is similar to .tm1, allowing leading whitespace. o The new `spreadwarn' request will make troff warn if spaces in an output line are widened by a given limit or more. o Use `warnscale' to change the scaling indicator troff will use for warning messages. o A new request `dei' (define indirect) has been added. The first and second parameter of `dei' are taken from string registers rather than directly; this very special request is needed to make `trace.tmac' independent from the escape character (which might even be disabled). o It is now possible to save and restore the escape character with two new requests `ecs' and `ecr'. o The new escape sequence \B'...' is an analogon to `\A': If the string within the delimiters is a valid numeric expression, return character `1', and `0' otherwise. o The new escape sequence `\:' inserts a zero-width break point. This is similar to `\%' but without a soft hyphen character. o The `tr' request can now map characters onto `\~'. o Calling the `fam' request without an argument switches back to the previous font family. o The new read-only register `.int' is set to a positive value if the last output line is interrupted (i.e., if the input line contains `\c'). o The `writem' request is not new, but hasn't been documented before. This is similar to `write' but instead of a string the contents of a given macro or string is written to a stream. o The read/write number register `hp' to get/set the current horizontal position relative to the input line isn't new but hasn't been documented properly before. o `\X' and `\Y' are now transparent for end-of-sentence recognition. o The `cu' request in nroff mode now works as documented (i.e., it underlines spaces also). Grog ---- o The grog script now works in non-compatibility mode also (which is the default). As usual, use the `-C' option to activate compatibility mode. Grops ----- o A new option `-P' resp. a new environment variable `GROPS_PROLOGUE' has been added to select a different prologue file. o The effect of the former `-mpsnew' option to access more Type 1 characters is now the default and no longer available. To get the old behaviour (i.e., emulation of some glyphs by composition) use `-mpsold'. Miscellaneous ------------- o For security reasons the following changes have been done: . The tmac.safer file has been replaced with a built-in solution; .open, .opena, .pso, .sy, and .pi are completely disabled in safer mode (which is the default); to enable these requests the `-U' command line flag must be used. . Files specified with the .mso request or given with the `-m' command line option, and hyphenation patterns loaded with `.hpf' are no longer searched in the current directory by default (besides the usual tmac path). Instead, the home directory is used. To add the current directory, either use the `-U' or `-M' command line option or set the GROFF_TMAC_PATH environment variable to an appropriate value. . troffrc, troffrc-end, and eqnrc are neither searched in the current nor in the home directory (even if -U is given). Use -M or GROFF_TMAC_PATH to change that. . Similarly, the current directory is no longer part of the font path. Use the `-F' command line option or the GROFF_FONT_PATH environment variable if you really need the current directory. o groff now installs its data files into /usr/local/share/groff/ by default, following the GNU standard. Additionally, a local tmac directory (by default /usr/local/share/groff/site-tmac) is scanned before the standard tmac directory. Wrapper files for system-specific macro packages (if necessary) are put into /usr/local/lib/groff/site-tmac; this directory is searched before the local tmac directory. o All programs now have option `-v' to show the version number; they exit immediately afterwards, following the GNU standards. Additionally, `--version' and `--help' have been added, doing the obvious actions. @ text @d3 1 a3 1 --- Makefile.in.orig Mon Sep 16 18:51:00 2002 d5 1 a5 1 @@@@ -169,7 +169,7 @@@@ tmac_an_prefix=\ @ 1.1 log @Initial revision @ text @d3 4 a6 20 --- src/include/Makefile.sub.orig Sun Jun 18 12:13:58 2000 +++ src/include/Makefile.sub @@@@ -30,12 +30,12 @@@@ @@$(SHELL) $(top_srcdir)/gendef.sh defs.h \ "PROG_PREFIX=\"$(g)\"" \ "DEVICE=\"$(DEVICE)\"" \ - "FONTPATH=\"$(fontpath)\"" \ - "MACROPATH=\"$(tmacpath)\"" \ - "INDEX_SUFFIX=\"$(indexext)\"" \ - "COMMON_WORDS_FILE=\"$(common_words_file)\"" \ - "DEFAULT_INDEX_DIR=\"$(indexdir)\"" \ - "DEFAULT_INDEX_NAME=\"$(indexname)\"" \ - "DEFAULT_INDEX=\"$(indexdir)/$(indexname)\"" + "FONTPATH=\"$(PREFIX)/share/groff/font:/usr/share/groff_font\"" \ + "MACROPATH=\"$(PREFIX)/share/groff/tmac:/usr/share/tmac\"" \ + "INDEX_SUFFIX=\".i\"" \ + "COMMON_WORDS_FILE=\"/usr/share/dict/eign\"" \ + "DEFAULT_INDEX_DIR=\"/usr/share/dict/papers\"" \ + "DEFAULT_INDEX_NAME=\"Ind\"" \ + "DEFAULT_INDEX=\"/usr/share/dict/papers/Ind\"" d8 6 a13 1 FORCE: @ 1.1.1.1 log @Initial import of groff-1.16.1 -- GNU groff text formatting system. @ text @@
