# Convert i18n texts to gettext

# Extracts all texts from the file i18n.c and creates language
|

# specific *.po files.

# Usage: i18n-to-gettext

|
||
|
||
# How to convert an actual plugin:
|
||
#
|
||
# - If your code contains something like
|
||
#
|
||
# const char *Text = "Some text";
|
||
# ...
|
||
# Function(tr(Text));
|
||
#
|
||
# you need to enclose the text constant in trNOOP(...), as in
|
||
#
|
||
# const char *Text = trNOOP("Some text");
|
||
#
|
||
# The actual usage of the tr() macro remains unchanged.
|
||
#
|
||
# - If you have comments following the texts in your i18n.c file
|
||
# that should be seen by the translators, move them from the
|
||
# i18n.c file into the file where the text is actually used,
|
||
# and mark them with the TRANSLATORS keyword, as in
|
||
#
|
||
# // TRANSLATORS: note the plural!
|
||
# Add(new cMenuEditIntItem( tr("Setup.EPG$Preferred languages"), ...
|
||
#
|
||
# - Fill in your email address in the line
|
||
# $MSGIDBUGS = "" ...
|
||
# below, so that users can reach you in case there is a problem
|
||
# with a message id.
|
||
#
|
||
# - Run this Perl script from within your plugin's source directory.
|
||
# This script will run 'xgettext' to extract all of your texts
|
||
# into a file named <pluginname>.pot. After that it will extract
|
||
# your existing i18n texts from the file i18n.c (or wherever you
|
||
# have defined them) and generate *.po files for all languages
|
||
# currently known by VDR.
|
||
#
|
||
# - Your Makefile will be automatically adjusted to allow for
|
||
# building the *.mo files necessary for supporting gettext().
|
||
# Please check carefully whether the automatic adjustments have
|
||
# succeeded, though. The modified Makefile will be written to
|
||
# Makefile.new, so you can call this script any numer of times
|
||
# in case you need to do some fine tuning of your texts (especially
|
||
# adding some trNOOP() in case the script reports "missing phrases".
|
||
# Once you're done converting your plugin source to using gettext,
|
||
# rename Makefile.new to Makefile.
|
||
#
|
||
# - You may want to remove the old internationalized texts from your
|
||
# source. Usually this means removing the files i18n.[hc], stripping
|
||
# i18n.o from the OBJS variable in the Makefile and removing all
|
||
# '#include "i18n.h"' lines from the rest of your source files.
|
||
# These steps are not done automatically.
|
||
|
||
# Check for the existence of a Makefile:
|
||
|
||
die "Makefile not found!" unless (-f "Makefile");
|
||
|
||
# Determine the plugin name:
|
||
|
||
$PLUGIN = `grep '^PLUGIN *=' Makefile | head -1` || die "can't find plugin name!";
|
||
$PLUGIN =~ s/.*= *(.*)\n/$1/;
|
||
die "can't find plugin name!" unless ($PLUGIN);
|
||
|
||
# Locate the file containing the texts:
|
||
|
||
$I18NFILE = "";
|
||
for ("i18n.c", "i18n.h", `ls *.c`) { # try i18n.[ch] explicitly first
|
||
chomp($f = $_);
|
||
if (-f $f && `grep tI18nPhrase $f`) {
|
||
$I18NFILE = $f;
