catfile [msgfile|- ...] |
gencat
utility generates a formatted message catalog
catfile from stdin or one or more message source text
files msgfile. The file catfile is
created if it does not already exist. If catfile does
exist, its messages are included in the new catfile. The
new message text defined in msgfile replaces the old
message text currently in catfile when the set and
message numbers match.
The generated message catalog contains message strings that will be retrieved using the catgets(3) library call. These messages are dynamically loaded by the Native Language Support (NLS) library at run time. Error messages are grouped into sets, and a program can load a particular set depending on which type, or language, of messages is desired.
$set
n comment$set
or end-of-file. The
n is the set identifier which is defined as a number
in the range [1, NL_SETMAX
]. Set identifiers
within a single source file need not be contiguous. Any string following
the set identifier is treated as a comment. If no
$set
directive is specified in a message text
source file, all messages will be located in the default message set
NL_SETD
.$delset
n commentNL_SETMAX
]. If a message set was created earlier
in the current file, or in a file previously read by the
gencat
command, this directive will remove it. Any
string following the set identifier is treated as a comment.$
comment$
followed by a space or tab
character is treated as a comment.NL_MSGMAX
] and the
message-text. The message-text
is read until the end of the line or a quote character (if one is
specified). The message-text is stored in the
message catalog with the set identifier specified by the last
$set
directive, and the message identifier
m. If the message-text is
empty and there is a space or tab character following the message
identifier, an empty string is stored in the message catalog. If no
message-text is provided, and if there is no space
or tab character following the message identifier, the message with the
message identifier m in the current set is removed
from the catalog. Message identifiers need not be contiguous within a
single set. The length of message-text must be in
the range [0, NL_TEXTMAX
].$quote
c$quote
directive is specified, then the current
quote character is unset.Empty lines and leading blanks in a message text source file are ignored. Any line beginning with any character other than those described above is ignored as a syntax error.
Text message strings may contain any characters and the following special characters and escape sequences.
Description | Symbol | Sequence |
newline | NL(LF) | \n |
horizontal tab | HT | \t |
vertical tab | VT | \v |
backspace | BS | \b |
carriage return | CR | \r |
form feed | FF | \f |
backslash | \ | \\ |
bit pattern | ddd | \ddd |
A bit pattern, \ddd
, consists of a
backslash followed by one, two, or three octal digits representing the value
of the character. The current quote character, if defined, may be escaped
with a backslash to generate the quote character. Any character following
the backslash ('\') other than those specified is ignored.
A backslash at the end of the line continues the message onto the next line. The following two lines are an example of such a message:
1 This message continues
\
Producing the following message:
1 This message continues on the next
line
gencat
utility exits 0 on success,
and >0 if an error occurs.
