i18n: add the tool to check Mercurial specific translation problems in *.po
Existing tool like "msgfmt --check" can check typical translation
problems (missing "%s" in msgstr, for example), but can't check
Mercurial specific ones.
For example, "msgfmt --check" can't check whether the translated
string given to "ui.promptchoice()" is correct or not, even though
problems like below cause run-time error or unexpected behavior:
- less or more choices than msgid,
- choices without '&', or
- choices with '&' followed by none
This patch adds the tool to check Mercurial specific translation
problems in *.po files.
Translations are optional:
$ "$TESTDIR/hghave" gettext || exit 80
#if no-outer-repo
Test that translations are compiled and installed correctly.
Default encoding in tests is "ascii" and the translation is encoded
using the "replace" error handler:
$ LANGUAGE=pt_BR hg tip
abortado: n?o foi encontrado um reposit?rio em '$TESTTMP' (.hg n?o encontrado)!
[255]
Using a more accomodating encoding:
$ HGENCODING=UTF-8 LANGUAGE=pt_BR hg tip
abortado: n\xc3\xa3o foi encontrado um reposit\xc3\xb3rio em '$TESTTMP' (.hg n\xc3\xa3o encontrado)! (esc)
[255]
Different encoding:
$ HGENCODING=Latin-1 LANGUAGE=pt_BR hg tip
abortado: n\xe3o foi encontrado um reposit\xf3rio em '$TESTTMP' (.hg n\xe3o encontrado)! (esc)
[255]
#endif
Test keyword search in translated help text:
$ HGENCODING=UTF-8 LANGUAGE=de hg help -k blättern

Check Mercurial specific translation problems in each *.po files, and
tool itself by doctest
$ cd "$TESTDIR"/../i18n
$ python check-translation.py *.po
$ python check-translation.py --doctest
$ cd $TESTTMP
