This enforces a consistent formatting for the PO files. The goal of this
is to avoid large diffs due to random and unnecessary reformatting.
We use the format of `msgcat`: this is also waht `msgmerge` produces and
it’s easy to replicate for people by installing Gettext and running
`dprint fmt`.
This is a follow-up to #1351 which started enforcing that the `msgid`
fields don’t change due to reformatting in a PR.
If this turns out to be cumbersome, then we can disable it again.
This updates each PO file to the date when it was last touched:
for po_file in po/*.po; do
POT_DATE=$(git log -1 --date=short --format=%ad $po_file)
sed -i -e 's/"POT-Creation-Date:.*"/"POT-Creation-Date:
'$POT_DATE'\\n"/' $po_file
done
The dates will be updated with `msgmerge` in the future via
https://github.com/google/mdbook-i18n-helpers/pull/87.
The dates here can be adjusted by hand if needed — the starting point
here only serves as a rough anchor to let us freeze the translations
from further updates. So if you know that you ran `msgmerge` most
recently on a given date, please update the file to that date in a later
PR.
Before, po/ru.po had these statistics:
217 translated messages, 35 fuzzy translations, 1529 untranslated
messages.
Afterwards, the statistics for po/ru.po is:
374 translated messages, 47 fuzzy translations, 2046 untranslated
messages.
The number of translated messages changed from 12% to 15%.
With this change, it becomes important to use the latest version of
mdbook-i18n-helpers when viewing the translation locally. To update to
the latest version, run
cargo install mdbook-i18n-helpers
You will now be able to serve the translation locally.
Part of #330.
