Files to be translated (LilyPond Contributor’s Guide)

#### Files to be translated

A translation of file `Documentation/en/foo/bar.baz` should be stored in file `Documentation/MY-LANGUAGE/foo/bar.baz`. Unmentioned files should not be translated.

The table below list recommended priorities (lower values mean higher priority) of files to be translated. Files of priority 1 should be submitted along all files generated by starting a new language in the same commit and thus be a unique patch. Translation of files marked with priority 2 should be committed to the git repository at the same time and thus sent in a single patch. Priority 1 files are required before requesting a language-specific mailing list `lilypond-xyz@gnu.org`. Files marked with priority 3 or lower may be submitted individually. For knowing how to commit your work to the git repository, preferably as a Merge Request, see Working with source code.

Only add translated files to the git repository! All other, untranslated files can be safely deleted. If necessary, skeleton files can be regenerated by calling the `new-lang` make target again (this doesn’t overwrite existing files).

> 1 | The website: `web.texi`, `web/introduction.itexi`, and `web/download.itexi`. Additionally, also translate `macros.itexi` and `search-box.ihtml`.
> 2 | The tutorial: `web/manuals.itexi`, `learning.tely`, `learning/installing.itely`, `learning/tutorial.itely`, and `learning/common-notation.itely`.
> 3 | Fundamental concepts in `learning/fundamental.itely`, as well as `usage.tely`, `usage/running.itely`, `usage/updating.itely`, and `web/community.itexi`.
> 4 | The Changes file: `changes.tely`.
> 5 | More useful information: `learning/tweaks.itely`, `learning/templates.itely`, and `usage/suggestions.itely`.
> 6 | The Notation Reference: `notation.tely`, all of `notation/*.itely`, and the snippets’ titles and descriptions.
> 7 | More tools: `usage/lilypond-book.itely` and `usage/external.itely`.
> 8 | The Essay and the guide to extend LilyPond: `essay.tely` and `essay/*.itely`, as well as `extending.tely` and `extending/*.itely`.
> 9 | The Music Glossary: `music-glossary.tely`.
> 10 | LilyPond Snippets: `snippets.tely`. A large portion of them is also included in the NR.

A special case is file `Documentation/po/MY-LANGUAGE.po`, which holds strings to translate. Currently, there are two helper scripts that access it during a documentation build:

- `www_post.py`, to post-process HTML pages. Some messages to translate are in its module `postprocess_html.py`, and strings in the `.po` file tagged with this file name have priority 1 for translation.
- `lilypond-book`, to automatically translate comments within `@lilypond` blocks. In the `.po` file, such strings are tagged with ‘(comment)’, and translating such strings has a very low priority.

  Strings tagged with other markers like ‘(variable)’ and ‘(context id)’ can be safely ignored for the time being; the same is true for strings tagged as being a `@node` or a sectioning command like `@appendix`.

  Note, however, that this `lilypond-book` feature is currently broken.

Do not mix up the `Documentation/po/` and `po/` directories! The latter holds translations of messages emitted by `lilypond` (the program) and various other tools; they are maintained externally by the Free Translation Project.
