gencat -- NLS catalog compiler
gencat output-file input-files...
The gencat utility merges the text NLS input files input-files... into a formatted message
catalog file output-file. The file output-file will be created if it does not already
exist. If output-file does exist, its messages will be included in the new output-file. If
set and message numbers collide, the new message text defined in input-files... will replace
the old message text currently contained in output-file.
The format of a message text source file is defined below. Note that the fields of a mes-
sage text source line are separated by a single space character: any other space characters
are considered to be part of the field contents.
$set n comment
This line specifies the set identifier of the following messages until the next $set or
end-of-file appears. The argument n is the set identifier which is defined as a number
in the range [1, (NL_SETMAX)]. Set identifiers must occur in ascending order within a
single source file, but need not be contiguous. Any string following a space following
the set identifier is treated as a comment. If no $set directive is specified in a
given source file, all messages will be located in the default message set NL_SETD.
$del n comment
This line deletes messages from set n from a message catalog. The n specifies a set
number. Any string following a space following the set number is treated as a comment.
A line beginning with $ followed by a space is treated as a comment.
A message line consists of a message identifier m in the range [1, (NL_MSGMAX)]. 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 character following the message identifier, an empty string is stored
in the message catalog. If the message-text is empty, and if there is no space charac-
ter following the message identifier, then the existing message in the current set with
the specified message identifier is deleted from the catalog. Message identifiers must
be in ascending order within a single set, but need not be contiguous. The
message-text length must be in the range [0, (NL_TEXTMAX)].
This line specifies an optional quote character c which can be used to surround
message-text so that trailing space or empty messages are visible in message source
files. By default, or if an empty $quote directive is specified, no quoting of
message-text will be recognized.
Empty lines in message source files are ignored. The effect of lines beginning with any
character other than those described above is undefined.
Text strings can contain the following special characters and escape sequences. In addi-
tion, if a quote character is defined, it may be escaped as well to embed a literal quote
\n line feed
\t horizontal tab
\v vertical tab
\r carriage return
\f form feed
\ooo octal number in the range [000, 377]
A backslash character immediately before the end of the line in a file is used to continue
the line onto the next line, e.g.:
1 This line is continued \
on this line.
If the character following the backslash is not one of those specified, the backslash is
The gencat utility exits 0 on success, and >0 if an error occurs.
