vgrindefs
—
language definition data base for
vgrind(1)
vgrindefs |
The vgrindefs
file contains all language
definitions for vgrind(1). The
data base is of the style
capfile(5).
The following table names and describes each field.
Name | Type | Description |
pb | str | regular expression for start of a procedure |
bb | str | regular expression for start of a lexical block |
be | str | regular expression for the end of a lexical block |
cb | str | regular expression for the start of a comment |
ce | str | regular expression for the end of a comment |
sb | str | regular expression for the start of a string |
se | str | regular expression for the end of a string |
lb | str | regular expression for the start of a character constant |
le | str | regular expression for the end of a character constant |
tl | bool | present means procedures are only defined at the top lexical level |
oc | bool | present means upper and lower case are equivalent |
kw | str | a list of keywords separated by spaces |
The following entry, which describes the C language, is typical of a language entry.
C|c::pb=^\d?*?\d?\p\d?\(\a?\):bb={:be=}:cb=/*:ce=*/:sb=":se=\e":\ :lb=':le=\e':tl:\ :kw=asm auto break case char continue default do double else enum\ extern float for fortran goto if int long register return short\ sizeof static struct switch typedef union unsigned while #define\ #else #endif #if #ifdef #ifndef #include #undef # define else endif\ if ifdef ifndef include undef:
Note that the first field is just the language name (and any variants of it). Thus the C language could be specified to vgrind(1) as "c" or "C".
Entries may continue onto multiple lines by giving a \ as the last
character of a line. Capabilities in vgrindefs
are
of two types: Boolean capabilities which indicate that the language has some
particular feature and string capabilities which give a regular expression
or keyword list.
vgrindefs
uses regular expression which
are very similar to those of ex(1)
and lex(1). The characters `^',
`$', `:' and `\' are reserved characters and must be "quoted" with
a preceding ‘\
’ if they are to be
included as normal characters. The metasymbols and their meanings are:
Unlike other regular expressions in the system, these match words and not characters. Hence something like "(tramp|steamer)flies?" would match "tramp", "steamer", "trampflies", or "steamerflies".
The keyword list is just a list of keywords in the language separated by spaces. If the "oc" boolean is specified, indicating that upper and lower case are equivalent, then all the keywords should be specified in lower case.
The vgrindefs
file format appeared in
4.2BSD.
