[pacman-dev] Translation of man pages
by Mario Blättermann 19 Sep '21

19 Sep '21

Hello, the translation help page [1] says: --- There are currently no efforts underway to include translated manual pages in the pacman codebase. However, this is not to say translations are unwelcome. If someone has experience with i18n man pages and how to best include them with our source, please contact the pacman-dev mailing list at pacman-dev(a)archlinux.org. --- OK, then let me introduce my approach. Although the man page translations are already maintained in the manpages-l10n project [2] for some years, I think it is it better to use Pacman's upstream tree instead. The external maintenance has some disadvantages: We download distribution packages, create the templates, translate them and release the translated man pages some months later. Besides this delay, we don't know how many users know about the existence of the translated versions. Having the translations in the upstream project (translated using Transifex) would be better, and the localized versions would be released with Pacman itself and always in sync with the English ones. See the attached patch and config file. The patch manpage-markup.diff fixes the Asciidoc markup to get Po4a [3] properly working. After applying the patch, put po4a.cfg in doc/po/. I've imported German, Brazilian Portuguese and French translations from manpages-l10n, but even compressed they are too big for the list. The .po files will follow in separate mails.To test the creation of the translated Asciidoc files, just run 'po4a po4a.cfg'. This command creates a translation template and a subdirectory for each language and saves the resulting files there. Once you have the Asciidoc files, they can be processed further like those in doc/. Unfortunately, I don't have neither Autotools nor Meson knowledge, maybe someone else can help with integration into the build systems?

[pacman-dev] [PATCH] Update broken links pointing to git.archlinux.org

All of these links are broken since the recent move to gitlab.archlinux.org. A few projects are, apparently, only available on GitHub, so I've linked to that source (hopefully that's only temporary).

[pacman-dev] [PATCH 1/2] only use effective url for urls containing .db or .pkg
by morganamilo 03 Sep '21

03 Sep '21

Github and other sites redirect their downloads to a cdn. So the download http://foo.org/myrepo.db may redirect to something like https://cdn.foo.org/83749327439. This then causes pacman to try and download the sig as https://cdn.foo.org/83749327439.sig which is incorrect. In this case pacman should append .sig to the original url. However urls like https://archlinux.org/packages/community/x86_64/0ad/download/ Redirect to the mirror, so .sig has to appended after the redirects and not before. So we decide if we should append .sig on the original or effective url based on if the effective url has .db or .pkg in it.

[pacman-dev] Multiple progress bars not compatible with dumb terminals
by miha＠kamnitnik.top 29 Jun '21

29 Jun '21

On less capable terminals, pacman should probably display only one active progress bar simultaneously. An example of such a terminal is Emacs's M-x shell ($TERM == "dumb"). It can't display the additional "total" properly because it doesn't implement cursor movement.

[pacman-dev] [PATCH] doc: use localdate instead of pacman_date to improve reproducibility
by Jonas Witschel 25 Jun '21

25 Jun '21

pacman_date is set to the current date during build without respecting SOURCE_DATE_EPOCH. As a result, a build cannot be fully reproduced on a later date because the date embedded into the man pages does not match. In contrast, the built-in asciidoc attribute "localdate" respects SOURCE_DATE_EPOCH and has the desired ISO 8601 format, so simply use that instead of the custom "pacman_date" attribute.
