NAME
gencat — generate a formatted message catalog file
SYNOPSIS
gencat
[-l]
catfile
msgfile ...
DESCRIPTION
Message catalogs allow a program to process input and produce output
according to local customs and languages.
For details, see
Native Language Support Users Guide.
The
gencat
command merges each message source
msgfile
into a formatted message catalog
catfile
that can be accessed by
catgets()
(see
catgets(3C)).
If
catfile
does not exist, it is created.
If
catfile
exists, its messages are included in the new
catfile.
If set and message numbers collide, the new message text in
file
replaces the old message text in
catfile.
A
msgfile
consists of message, directive, and comment lines
(all without leading spaces or tabs) described below.
Except as noted,
fields are separated by one or more space or tab characters.
If
-
is specified as catalog file, standard output is used.
If
-
is specified for an instance of message file, standard input is used.
- $set s [comment]
A
$set
directive specifies the set
s,
of the messages that follow until the next
$set
or end-of-file appears.
The set number
s
is an unsigned integer in the range 1 through
NL_SETMAX.
Any string following the set number is treated as a comment.
If a
$set
directive is not specified, messages are put in the default set
NL_SETD.
Set numbers must be in ascending order within a
msgfile
but need not be contiguous.
- $delset s [comment]
A
$delset
directive deletes the message set identified by the set number
s,
from an existing message catalog.
Any string following the set number is treated as a comment.
- m message_text
A message line specifies a message number
m,
and associated message text.
The message number
m
is an unsigned integer in the range 1 through
NL_MSGMAX.
The
message_text
is a C string, including spaces, tabs and \ (backslash) escapes,
but by default without surrounding quotes (see
$quote
directive below).
The message number
m
is separated from the
message_text
by a single space or tab character.
The
message_text
begins with the first character following the separator
and ends at new-line.
Extra spaces or tabs (including any trailing spaces or tabs)
are considered part of the
message_text.
The
message_text
of a message line is stored in
catfile
with message number
m
and set number
s
specified by the most recent
$set
directive.
Message numbers must be in ascending order within a set,
but need not be contiguous.
Note that the space or tab separator
distinguishes insertion of a null message from deletion of a message.
If a message line has a number and separator but no text,
the message number and an associated null message string are stored in
catfile.
If a message line has a number but neither separator nor text,
the message number and its associated message text are deleted from
catfile.
- -l
If the
-l
option is specified, the length of
message_text
must be no more than
MAX_BUFLEN
- 1 bytes.
If the
-l
option is not specified, the length of
message_text
must be no more than
NL_TEXTMAX
bytes.
See
catgets(3C),
for message length limits imposed by these routines.
- $quote [q comment]
A
$quote
directive specifies a quote character
q,
used to surround
message_text
and make leading and trailing space visible in a message line.
Any string following the specified quote character
q
is treated as a comment.
By default, or if a quote character
q
not is supplied, quoting of
message_text
is not recognized.
- $ comment
A
$
followed by a space or tab is treated as a comment
and can appear anywhere in a file.
A line consisting of zero or more spaces or tabs
is treated as a comment line.
NL_TEXTMAX,
NL_SETMAX,
and
NL_MSGMAX
are defined in
<limits.h>.
NL_SETD
is defined in
<nl_types.h>.
MAX_BUFLEN
is defined in
<msgcat.h>.
EXTERNAL INFLUENCES
Environment Variables
LANG
provides a default value for the internationalization
variables that are unset or null.
If
LANG
is unset or null, the default value of "C" (see
lang(5))
is used.
If any of the internationalization variables contains an invalid setting,
gencat
will behave as if all internationalization variables are set to "C".
See
environ(5).
LC_ALL,
if set to a non-empty string value, overrides the values of all of the other
internationalization variables.
LC_CTYPE
determines the interpretation of text as single and/or
multi-byte characters,
the classification of characters as printable,
and the characters matched by character class
expressions in regular expressions.
LC_MESSAGES
determines the locale that should be used to affect the format
and contents of diagnostic messages written to
standard error and informative messages
written to standard output.
NLSPATH
determines the location of message catalogs for the processing of
LC_MESSAGES.
International Code Set Support
Single- and multi-byte character code sets are supported.
WARNINGS
The
$quote
directive is not currently supported on the
HP MPE and RTE
operating systems.
