.Sh NAME
|
|
.Nm gencat
|
|
.Nd NLS catalog compiler
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Ar "output-file"
|
|
.Ar "input-files..."
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility merges the text NLS input files
|
|
.Ar "input-files..."
|
|
into a formatted message catalog file
|
|
.Ar "output-file" .
|
|
The file
|
|
.Ar "output-file"
|
|
will be created if it does not already exist. If
|
|
.Ar "output-file"
|
|
does exist, its messages will be included in the new
|
|
.Ar "output-file" .
|
|
If set and message numbers collide, the new message text defined in
|
|
.Ar "input-files..."
|
|
will replace the old message text currently contained in
|
|
.Ar "output-file" .
|
|
.Sh INPUT FILES
|
|
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.
|
|
.Pp
|
|
.Bl -tag -width
|
|
.It Li $set Ar n comment
|
|
This line specifies the set identifier of the following messages until
|
|
the next
|
|
.Li $set
|
|
or end-of-file appears. The argument
|
|
.Ar 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
|
|
.Li $set
|
|
directive is specified in a given source file, all messages will
|
|
be located in the default message set NL_SETD.
|
|
.It Li $del Ar n comment
|
|
This line deletes messages from set
|
|
.Ar n
|
|
from a message catalog. The
|
|
.Ar n
|
|
specifies a set number. Any string following a space following the set
|
|
number is treated as a comment.
|
|
.It Li $ Ar comment
|
|
A line beginning with
|
|
.Li $
|
|
followed by a space is treated as a comment.
|
|
.It Ar m message-text
|
|
A message line consists of a message identifier
|
|
.Ar m
|
|
in the range [1, (NL_MSGMAX)]. The
|
|
.Ar message-text
|
|
is stored in the message catalog with the set identifier specified by
|
|
the last
|
|
.Li $set
|
|
directive, and the message identifier
|
|
.Ar m .
|
|
If the
|
|
.Ar 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
|
|
.Ar 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
|
|
.Ar message-text
|
|
length must be in the range [0, (NL_TEXTMAX)].
|
|
.It Li $quote Ar c
|
|
This line specifies an optional quote character
|
|
.Ar c
|
|
which can be used to surround
|
|
.Ar message-text
|
|
so that trailing space or empty messages are visible in message
|
|
source files. By default, or if an empty
|
|
.Li $quote
|
|
directive is specified, no quoting of
|
|
.Ar message-text
|
|
will be recognized.
|
|
.El
|
|
.Pp
|
|
Empty lines in message source files are ignored. The effect of lines
|
|
beginning with any character other than those described above is
|
|
undefined.
|
|
.Pp
|
|
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.

.Pp
|
|
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.:
|
|
.Pp
|
|
.Dl 1 This line is continued \e
|
|
.Dl on this line.
|
|
.Pp
|
|
If the character following the backslash is not one of those specified,
|
|
the backslash is ignored.
