msgcc - C language message catalog compiler SYNOPSIS
msgcc [-M-option] [cc-optionsoption] file... DESCRIPTION
msgcc is a C language message catalog compiler. It accepts cc style options and arguments. A msgcpp(1) .mso file is generated for each input .c file. If the -c option is not specified then a gencat(1) format .msg file is generated from the input .mso and .msg files. If -c is not specified then a .msg suffix is appended to the -o file if it doesn't already have a suf- fix. The default output is a.out.msg if -c and -o are not specified. If -M-new is not specified then messages are merged with those in the pre-existing -o file. OPTIONS
The following options are supported: cc-options Specify cc style options and arguments. -M-option Set a msgcc option. Specify option as one of the following: mkmsgs The -o file is assumed to be in mkmsgs(1) format. new Create a new -o file. preserve Messages in the -o file that are not in new .msg file arguments are preserved. The default is to either re- use the message numbers with new message text that is similar to the old or to delete the message text, leaving an unused message number. set=number Set the message set number to number. The default is 1. similar=number The message text similarity message threshold. The similarity measure between old and new message text is: 100*(2*gzip(old+new) /(gzip(old)+gzip(new))-1) where gzip(x) is the size of text x when compressed by gzip. The default threshold is $__similar__$.A threshold of 0 turns off message replacement, but unused old messages are still deleted. Use -M-preserve to preserve all old messages. verbose Trace similar message replacements on the standard error. OPERANDS
The following operands are supported: file Specifies the name of the file on which msgcc operates. EXIT STATUS
0 Successful completion. >0 An error occurred. EXAMPLES
Example 1 Using msgcc The following example uses msgcc to extract localizable strings from the file hello.c, marked using ERROR_dictionary(), writes them to the file hello.mso, and creates a gencat format xxx.msg file: example% cat hello.c #include <stdio.h> #include <stdlib.h> /* * dummy macro to avoid including * libast headers */ #define ERROR_dictionary(x) x int main(int ac, char *av[]) { puts( ERROR_dictionary("hello world") ); return( EXIT_SUCCESS ); } example% msgcc -o xxx -D__STDC__ -D__i386 hello.c example% cat hello.mso str "hello world" example% cat xxx.msg $ xxx message catalog $translation msgcc 2007-09-25 $set 1 $quote " 1 "hello world" AUTHORS

genmsg - generate a message source file by extracting messages from source files SYNOPSIS
genmsg [-abdfrntx] [-c message-tag] [-g project-file] [-l project-file] [-m prefix] [-M suffix] [-o message-file] [-p preprocessor] [-s set-tags] file... DESCRIPTION
The genmsg utility extracts message strings with calls to catgets(3C) from source files and writes them in a format suitable for input to gencat(1). Invocation genmsg reads one or more input files and, by default, generates a message source file whose name is composed of the first input file name with .msg. If the -o option is specified, genmsg uses the option argument for its output file. +-------------------------------------+---------------------+ |Command | Output File | +-------------------------------------+---------------------+ |genmsg prog.c | prog.c.msg | |gensmg main.c util.c tool.c | main.c.msg | |genmsg -o prog.msg mail.c util.c | prog.msg | +-------------------------------------+---------------------+ genmsg also allows you to invoke a preprocessor to solve the dependencies of macros and define statements for the catgets(3C) calls. Auto Message Numbering genmsg replaces message numbers with the calculated numbers based upon the project file if the message numbers are -1, and it generates copies of the input files with the new message numbers and a copy of the project file with the new maximum message numbers. A project file is a database that stores a list of set numbers with their maximum message numbers. Each line in a project file is composed of a set number and its maximum message number: Set_number Maximum_message_number In a project file, a line beginning with a number sign (#) or an ASCII space is considered as a comment and ignored. genmsg also has the reverse operation to replace all message numbers with -1. Comment Extraction genmsg allows you to comment about messages and set numbers to inform the translator how the messages should be translated. It extracts the comment, which is surrounded with the comment indicators and has the specified tag inside the comment, from the input file and writes it with a dollar ($) prefix in the output file. genmsg supports the C and C++ comment indicators, '/*', '*/', and '//'. Testing genmsg generates two kinds of messages for testing, prefixed messages and long messages. Prefixed messages allow you to check that your program is retrieving the messages from the message catalog. Long messages allow you to check the appearance of your window program's ini- tial size and position. OPTIONS
The following options are supported: -a Append the output into the message file message-file that is specified by the -o option. If two different messages that have the same set and message number are found, the message in the specified message file is kept and the other message in the input file is discarded. -b Place the extracted comment after the corresponding message in the output file. This option changes the placement behav- ior of the -s or -c option. -c message-tag Extract message comments having message-tag inside them from the input files and write them with a '$' prefix as a com- ment in the output file. -d Include an original text of a message as a comment to be preserved along with its translations. With this option, the translator can see the original messages even after they are replaced with their translations. -f Overwrite the input files and the project file when used with the -l or -r option. With the -r option, genmsg overwrites only the input files. -g project-file Generate project-file that has a list of set numbers and their maximum message numbers in the input files. -l project-file Replace message numbers with the calculated numbers based upon project-file if the message numbers are -1 in the input files, and then generate copies of the input files with the new message numbers and a copy of project-file with the new maximum message numbers. If project-file is not found, genmsg uses the maximum message number in the input file as a base number and generates project-file. -m prefix Fill in the message with prefix. This option is useful for testing. -M suffix Fill in the message with suffix. This option is useful for testing. -n Add comment lines to the output file indicating the file name and line number in the input files where each extracted string is encountered. -o message-file Write the output to message-file. -p preprocessor Invoke preprocessor to preprocess macros and define statements for the catgets(3C) calls. genmsg first invokes the option argument as a preprocesser and then starts the normal process against the output from the preprocessor. genmsg initiates this process for all the input files. -r Replace message numbers with -1. This is the reverse operation of the -l option. -s set-tag Extract set number comments having set-tag inside them from the input files and write them with a '$' prefix as a com- ment in the output file. If multiple comments are specified for one set number, the first one is extracted and the rest of them are discarded. -t Generate a message that is three times as long as the original message. This option is useful for testing. -x Suppress warning messages about message and set number range checks and conflicts. OPERANDS
file An input source file. EXAMPLES
Example 1 Assigning Message Numbers and Generating New Files Suppose that you have the following source and project files: example% cat test.c printf(catgets(catfd, 1, -1, "line too long ")); printf(catgets(catfd, 2, -1, "invalid code ")); example% cat proj 1 10 2 20 The command example% genmsg -l proj test.c would assign the calculated message numbers based upon proj and generate the following files: test.c.msg Message file proj.new Updated project file test.c.new New source file example% cat test.c.msg $quote " $set 1 11 "line too long " $set 2 21 "invalid code " example% cat proj.new 1 11 2 21 example% cat test.c.new printf(catgets(catfd, 1, 11, "line too long ")); printf(catgets(catfd, 2, 21, "invalid code ")); Example 2 Extracting Comments Into a File The command example% genmsg -s SET -c MSG test.c example% cat test.c /* SET: tar messages */ /* MSG: don't translate "tar". */ catgets(catfd, 1, 1, "tar: tape write error"); // MSG: don't translate "tar" and "-I". catgets(catfd, 1, 2, "tar: missing argument for -I flag"); would extract the comments and write them in the following output file: example% cat test.c.msg $ /* SET: tar messages */ $set 1 $ /* MSG: don't translate "tar". */ 1 "tar: tape write error" $ // MSG: don't translate "tar" and "-I". 2 "tar: missing argument for -I flag" Example 3 Generating Test Messages The following command: example% genmsg -m PRE: -M :FIX test.c might generate the following messages for testing: example% cat test.c.msg 1 "PRE:OK:FIX" 2 "PRE:Cancel:FIX" Example 4 Parsing a Macro and Writing the Extracted Messages Given the following input: example% cat example.c #include <nl_types.h> #define MSG1 "message1" #define MSG2 "message2" #define MSG3 "message3" #define MSG(n) catgets(catd, 1, n, MSG ## n) void main(int argc, char **argv) { nl_catd catd = catopen(argv[0], NL_CAT_LOCALE); (void) printf("%s0 , MSG(1)); (void) printf("%s0 , MSG(2)); (void) printf("%s0 , MSG(3)); (void) catclose(catd); } The following command: example% genmsg -p "cc -E" -o example.msg example.c would parse the MSG macros and write the extracted messages in example.msg. Example 5 Assigning Calculated Message Numbers Suppose that you have the following header, source, and project files: example% cat ../inc/msg.h #define WARN_SET 1 #define ERR_SET 2 #define WARN_MSG(id, msg) catgets(catd, WARN_SET, (id), (msg)) #define ERR_MSG(id, msg) catgets(catd, ERR_SET, (id), (msg)) example% example.c #include "msg.h" printf("%s, WARN_MSG(-1, "Warning error")); printf("%s, ERR_MSG(-1, "Fatal error")); example % proj 1 10 2 10 The command example% genmsg -f -p "cc -E -I../inc" -l proj -o example.msg example.c would assign each of the -1 message numbers a calculated number based upon proj and would overwrite the results to example.c and proj. Also, this command writes the extracted messages in example.msg. ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of genmsg: LC_MESSAGES and NLSPATH. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. ATTRIBUTES

gencat(1), catgets(3C), catopen(3C), attributes(5), environ(5) NOTES
genmsg does not handle pointers or variables in the catgets(3C) call. For example: const int set_num = 1; extern int msg_num(const char *); const char *msg = "Hello"; catgets(catd, set_num, msg_num(msg), msg); When the auto message numbering is turned on with a preprocessor, if there are multiple -1's in the catgets(3C) line, genmsg replaces all of the -1's in the line with a calculated number. For example, given the input: #define MSG(id, msg) catgets(catd, 1, (id), (msg)) if (ret == -1) printf("%s, MSG(-1, "Failed")); the command genmsg -l proj -p "cc -E" would produce: #define MSG(id, msg) catgets(catd, 1, (id), (msg)) if (ret == 1) printf("%s, MSG(1, "Failed")); The workaround would be to split it into two lines as follows: if (ret == -1) printf("%s, MSG(-1, "Failed")); SunOS 5.11 14 May 2004 genmsg(1)
