Add Catalan and Spanish translation with gotext[3] I had to choose between [1], [2], and [3]. As far as i could find, [1] is not easy to work with templates[4] and at the moment is not maintained[5]. Both [2] and [3] use the same approach to be used from within templates: you have to define a FuncMap with template functions that call the message catalog. Also, both libraries seems to be reasonably maintained, and have packages in Debian’s repository. However, [2] repeats the same mistakes that POSIX did with its catalogs—using identifiers that are not the strings in the source language—, however this time the catalogs are written in JSON or YAML! This, somehow, makes things worse…. [3], the one i settled with, is fine and decently maintained. There are some surprising things, such as to be able to use directly the PO file, and that it has higher priority over the corresponding MO, or that the order of parameters is reversed in respect to gettext. However, it uses a saner format, and is a lot easier to work with than [3]. The problem, of course, is that xgettext does not know how to find translatable strings inside the template. [3] includes a CLI tool similar to xgettext, but is not a drop-in replacement[6] and does not process templates. The proper way to handle this would be to add a parser to xgettext, but for now i found out that if i surround the call to the translation functions from within the template with parentheses, i can trick xgettext into believing it is parsing Scheme code, and extracts the strings successfully—at least, for what i have tried. Had to add the keyword for pgettext, because Schemed does not have it, but at least i can do that with command line parameters. For now i left only Spanish and Catalan as the two available languages, even though the source text is written in English, because that way i can make sure i do not leave strings untranslated.
