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 message 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.
$
comment
- A line beginning with
$
followed by a space is
treated as a comment.
- m message-text
- 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
character 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)].
$quote
c
- 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 addition, if a quote character is defined, it may be
escaped as well to embed a literal quote character.
\n
- line feed
\t
- horizontal tab
\v
- vertical tab
\b
- backspace
\r
- carriage return
\f
- form feed
\\
- backslash
\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 ignored.
The gencat
utility exits 0 on success,
and >0 if an error occurs.
The gencat
utility is compliant with the
X/Open Portability Guide Issue 4
(“XPG4”) standard.

A message catalog file created from a blank input file cannot be revised; it
must be deleted and recreated.
