I use this kind of thing for a website in SPIP (mix of HTML, php and
pseudo-HTML language). There is two parts to consider:
1) extract original text to create the POT file
2) use gettext to get the correct translation
Of cause, between 1 and 2, you have to translate, compile translations (po->mo)
install translations in the correct place, ... but all of this is very standard.
In the po/ directory of my website, I have:
======
all:
@echo "use 'make file.po' to update the po file from the pot file if
needed"
%.po: LIG-spip.pot
msgmerge --verbose --update $@ $<
touch $@
update: $(wildcard *.po)
======
And in the main Makefile (in ./):
======
GETTEXT_DOMAIN=Project_name
LANGAGES=fr de
locale/%/LC_MESSAGES/$(GETTEXT_DOMAIN).mo: po/%.po
mkdir -p locale/$*/LC_MESSAGES
msgfmt --check -D po --output-file=$@ $*.po
translations: po/$(GETTEXT_DOMAIN).pot $(foreach
lang,$(LANGAGES),locale/$(lang)/LC_MESSAGES/$(GETTEXT_DOMAIN).mo)
po/$(GETTEXT_DOMAIN).pot: [All source files]
complex scripts to extract info in a pot file as gettext does not know
SPIP dialect
======
As shell scripts are managed by xgettext, I think that a simple command
to create the pot file should be enough. Something as (not tested):
XGETTEXT=xgettext \
[EMAIL PROTECTED] \
--from-code=UTF-8 \
--copyright-holder=PROJECT_NAME \
--sort-by-file
po/$(GETTEXT_DOMAIN).pot: [all script files]
$(XGETTEXT) --output-dir=po --default-domain $(GETTEXT_DOMAIN)
--language Shell $^
sed -i po/$(GETTEXT_DOMAIN).po -e 's,^"Content-Type: text/plain;
charset=CHARSET\\n"$$,"Content-Type: text/plain; charset=UTF-8\\n",'
@if test -f $@ ; then \
REP="$$(grep '^"POT-Creation-Date: [0-9 :+-]*\\n"$$' $@ | sed
-e 's/\\/\\\\/g' )" ; \
sed -i po/$(GETTEXT_DOMAIN).po -e 's,^"POT-Creation-Date: [0-9
:+-]*\\n"$$,'"$$REP"',' ; \
fi
@REP="$$(grep '^"POT-Creation-Date: [0-9 :+-]*\\n"$$'
po/$(GETTEXT_DOMAIN).po | sed -e 's/\\/\\\\/g' )" ; \
if ! diff -u $@ po/$(GETTEXT_DOMAIN).po ; then \
mv po/$(GETTEXT_DOMAIN).po $@ ;\
sed -i $@ -e 's,^"POT-Creation-Date: [0-9 :+-]*\\n"$$,'$$REP','
;\
echo "********************" ;\
echo "$@ has been modified. Translations probably need to be
updated" ; \
echo "********************" ;\
$(MAKE) -C po update ;\
else \
mv po/$(GETTEXT_DOMAIN).po $@ ;\
fi
Note that all file manipulation to avoid to change the file if it is the
same (but the date) is perhaps due to #496282 (now fixed in testing but I did
not recheck
my Makefiles (and they must work on older system anyway))
Of course, in your scripts, you need to call gettext. Some idea (not tested at
all):
======
MYGETTEXT=''
# This function must be called 'gettext'
# so that xgettext find the string to translate
gettext() {
if test -n "MYGETTEXT"; then
if test -x "$(which gettext)" ; then
MYGETTEXT="$(which gettext) -d Project_name -s"
else
MYGETTEXT="echo"
fi
fi
$MYGETTEXT "$1"
}
# gettext is a replacement for echo
gettext coucou
BASEDIR=www.debian.org
#Wrong: $BASEDIR never interpreted by the shell
ARG="$(gettext '$BASEDIR/file.en.html')"
echo "$ARG"
#Wrong: $BASEDIR interpreted before gettext called
#but xgettext cannot extract it:
ARG="$(gettext "$BASEDIR/file.en.html")"
echo "$ARG"
#Right: $BASEDIR not interpreted before gettext called but after (translators
#must keep $BASEDIR in their translation)
#xgettext can extract the message:
ARG="$(eval echo "$(gettext '$BASEDIR/file.en.html')")"
echo "$ARG"
