Redmine

h1. HowTo translate Redmine to your own language

Redmine can easily be translated to any language.

There are a few things to translate:

* The main lang file, located at source:/trunk/config/locales in current trunk

* The wiki toolbar lang file, located in source:trunk/app/assets/javascripts/jstoolbar/lang/

* The six bundled help files, located in source:app/views/help/wiki_syntax/ under a subdir named after the language subtag

Say you want to translate Redmine to Finnish (@fi@ as defined in the "IANA Language Subtag Registry":http://www.iana.org/assignments/language-subtag-registry):

# Copy @/config/locales/en.yml@ to @/config/locales/fi.yml@.

# Copy @/app/assets/javascripts/jstoolbar/lang/jstoolbar-en.js@ to @/app/assets/javascripts/jstoolbar/lang/jstoolbar-fi.js@.

# Copy @/app/views/help/wiki_syntax/textile/en/*@ to @/app/views/help/wiki_syntax/textile/fi/*@.

# Change the @general_lang_name@ key with the full name of the new language in @fi.yml@ (eg. @general_lang_name: Finnish@).

# Clear the application cache to make the new language available in Redmine (eg. @rake tmp:cache:clear@).

Then:

# Translate every string in _fi.yml_ and _jstoolbar-fi.js_ files and translate the content of the four help files (_wiki_syntax_textile.html_, _wiki_syntax_markdown.html_, _wiki_syntax_detailed_textile.html_ & _wiki_syntax_detailed_markdown.html_).

# Test your translation with the rake tasks listed [[HowTo_translate_Redmine_in_your_own_language#Test-rake-tasks|below]]. If you get errors related to locales, you must fix them.

# Submit your translation "here":http://www.redmine.org/projects/redmine/issues/new?tracker_id=3 (as plain file or patch, login required). Select "Translation" in Category listbox.

# Wait until your Issue will be fixed.

# Enjoy your work :)

# GOTO 4 if needed.

h3. Test rake tasks

Test if translation files can be parsed without errors and there are no missing keys

<pre>

rake locales:check_interpolation

</pre>

Whole test (Optional)

<pre>

rake test

</pre>

"rake test" takes a very long time and it runs automatically on CI server.

See [[Continuous integration]].

h2. Restrictions

*All these files must be UTF-8 encoded.* Do not use HTML entities in translated strings.

Check that your files do not have a BOM (Byte-order mark). A BOM can be removed with the following command:

<pre>

awk '{if(NR==1)sub(/^\xef\xbb\xbf/, "");print}' < oldfile > newfile

</pre>

As of 2009-02-21, *only updates based on the new translation files* (found in @/config/locales@) *should be submitted.*

h2. Updates to the language files

The file: "@en.yml@" acts as the main language file. You can check if it has new strings by running:

<pre>rake locales:update</pre>

This copies any new strings to other translation files (with the English translation as default value).
