Localization (L10N) of Trac

This page is here to propose and discuss Trac changes to support localization (L10N).

Possible Goals

First of all let's define all possible goals. Feel free to add your own. It is understood that not all of them can be necessarily implemented.


I18N is not only translation, it is also a bunch of other things. Since currency or paper size or units of measurement are not relevant here, the most important aspect besides translation is the format of time and date. Trac, unfortunately, uses the least sensible date format throughout, with the day between month and year. The date format should be configurable, and the default, as this is a technical environment should be ISO, such as 2005-07-29.


  • We need an easy way to translate wiki pages. It should help and encourage people to translate a particular page into their native language.
  • It should be possible to quickly switch between different versions of the same page. May be we should give the possibility to compare different versions on one page.
  • We have to give the way to set the prefered language.
  • There should be a way to quickly check if the translation is current with respect to the original (English) version.


For the project to be localized, the actual interface would have to be translated as well. How difficult would it be to translate the interface to say, Japanese? If possible it should be a user preference, which may require some additional changes. If possible it may be best if one could come up with an array of the most important terms derived from the wiki pages described below to be used in auto translating the interface.

Terms (Definitions)

Consistent and careful translation of terms like timeline, ticket, report is very important. These terms are used everywhere and must be easy to remember and comfortable to use.

The way to make up good translations of important terms is to discuss them before using everywhere. The easiest way to accomplish it is to set up wiki pages for different languages. See, for example TracTermsPtBr, TracTermsEs, TracTermsFr, TracTermsKo ,TracTermsRu, TracTermsJa, TracTermsDe, TracTermsLv, TracTermsPl, TracTermsEl. Add your own using TracTermsEn as an example.

Other Implementations

How does other software (especially wiki-software) deal with the problem of L10N? This section is devoted to describing and linking existing solutions.


The famous Wikipedia has a huge collection of translations. How do they do it?

Temporary Workaround: Template Translation

Can it be useful? I think so. trac-0.9.1-templates-pt-br.tar.gz
