caterr - Processes message text files
caterr [-c catfile] [-e] [-s[-P cpp_opts]] [-Y x,pathname] [msgfile]
UNICOS systems
IRIX systems
A message catalog is a binary file that contains the run-time source
of error messages output by UNICOS software products. A message
catalog is produced from a message text file that contains messages
(tagged with $msg tags) and message explanations (tagged with $nexp or
$exp tags).
Before it can be accessed at run time, a message text file must be
converted to a message catalog binary file by the caterr processor and
the gencat(1) catalog generator.
The caterr utility converts the error message text source in msgfile
into the format used as input to gencat(1), the error message catalog
generation utility. If msgfile is not specified or if a dash (-) is
specified, caterr reads from the standard input.
The -c option to the caterr utility calls gencat(1) after processing
is complete. Using the -c option allows a catalog to be generated
from a message text file in one step. It is recommended that you use
caterr with the -c option. The gencat(1) utility exists as a separate
utility to maintain compatibility with industry standards for message
catalog processing. No advantage exists in calling genca
in the
/usr/bin/gencat file.
A single invocation of caterr can process either the messages or the
explanations in the input files, but not both. The caterr utility
processes the messages by default. Use the -e option to specify
processing of the explanations.
The caterr utility calls the text formatting utility nroff(1) to
process formatted explanations as part of its processing of the
message text file. nroff(1) uses message macro definitions to format
the explanation text. By default, on UNICOS systems, caterr looks for
nroff(1) in the /usr/bin/nroff file and for the message macros in the
/usr/lib/tmac/tmac.sg file. On IRIX systems, caterr looks for
nroff(1) in the /usr/bin/nroff file and for the message macros in the
/usr/share/lib/tmac/tmac.sg file.
If no options are specified, caterr processes msgfile by using the
tools in the default locations. The output, suitable for input to
gencat(1), is sent to stdout.
The caterr utility accepts the following options and arguments:
-c catfile
(Catalog) Calls gencat(1) to update or create a catalog with
the information in the processed msgfile. If the -c option
is used, caterr invokes gencat(1) to update the specified
catalog by using the generated output. If catfile does not
exist, it is created. Using the -c option makes it
unnecessary to call gencat(1) separately; the message
catalog is generated in one step.
-e (Explanations) Processes the explanations in msgfile.
Without the -e option, caterr processes the messages in
msgfile.
-s[-P cpp_opts]
(Symbolic names) Calls the C language preprocessor (cpp(1))
to preprocess symbolic message names into message numbers.
The mapping of names to numbers must be specified in a
header file name in the input file. On UNICOS systems,
caterr looks for cpp(1) first in the /usr/gen/lib/cpp
directory. If it does not find it there, it looks in
/lib/cpp. On IRIX systems, caterr looks for cpp(1) in the
/lib/cpp directory.
Options can be passed to cpp by specifying the -P suboption
to the -s option. Place the options to be passed to cpp
within double quotation marks (" "). The entire string
within the quotation marks is passed to cpp for execution.
The -P suboption can be specified only if the -s option also
is specified.
-Y x,pathname
Specifies the version of the nroff(1) and gencat(1) tools
and of the tmac.sg message macros that caterr calls. If the
-Y option is not specified, caterr calls the version of
nroff(1) in /usr/bin/nroff, the version of gencat(1) in
/usr/bin/gencat, and the version of the message macros in
/usr/lib/tmac/tmac.sg (UNICOS systems) or
/usr/share/lib/tmac/tmac.sg (IRIX systems). If you need to
specify alternative paths for all three tools that caterr
calls, you can specify the -Y option up to three times in
the same command line.
The -Y option takes two arguments: a path name and a key
letter that specifies which software (nroff(1), gencat(1),
or the message macros) is located at that path name. The
key letter is specified first, followed by a comma (,),
followed by the path name. The alternative tool path
specified with pathname must be a full path.
The -Y option accepts the following key letters:
c Specifies that the path name following the comma is the
path name for gencat(1).
m Specifies that the path name following the comma is the
path name for the message macros.
n Specifies that the path name following the comma is the
path name for nroff(1).
msgfile Specifies the name of the file containing the message text
source to be processed.
Example 1: In the following example, caterr processes the messages in
file ldr.msg. The output, sent to stdout, is suitable for input to
gencat(1).
caterr ldr.msg
Example 2: In the following example, caterr invokes gencat(1) to
update the messages in the ldr.cat catalog with the information in
file ldr.msg.
caterr -c ldr.cat ldr.msg
Example 3: In the following example, caterr uses the message macros
in the file /usr/me/errmsg/tmac.sg to produce a catalog of
explanations suitable for processing by gencat(1). The input file is
ldr.msg; the output is sent to stdout.
caterr -e -Y m,/usr/me/errmsg/tmac.sg ldr.msg
Example 4: In the following example, caterr uses the message macros
in the current directory and invokes gencat(1) from /bin/gencat to
update the explanation catalog ldr.exp with the information in
ldr.msg.
caterr -e -c ldr.exp -Y m,tmac.sg -Y c,/bin/gencat ldr.msg
Example 5: In the following example, caterr calls nroff from
/usr/me/errmsg/nroff and uses the message macros in the current
directory. The input file is ldr.msg. Explanations suitable for
processing by gencat(1) are output to stdout.
caterr -e -Y n,/usr/me/errmsg/nroff -Y m,tmac.sg ldr.msg
Example 6: In the following example, caterr calls alternative
versions of all three tools. It uses the versions of nroff(1) and the
message macros in the current directory, and it calls gencat(1) from
/bin/gencat. Using these tools, the explanations in the ldr.exp file
are updated with the information in the ldr.msg file.
caterr -e -c ldr.exp -Y c,/bin/gencat -Y m,tmac.sg -Y n,nroff ldr.msg
Example 7: In the following example, caterr invokes gencat(1) to
update the messages in the ldr.cat catalog with the information in the
ldr.msg file. The caterr utility calls cpp(1) to preprocess symbolic
message names, and passes the -M option to cpp(1) for execution.
caterr -c ldr.cat -s -P "-M" ldr.msg
Example 8: In the following example, caterr invokes gencat(1) to
update the ldr.cat catalog. Because no message text file name is
specified, the input to caterr is read from the standard input.
caterr -c ldr.cat
