Internationalization

This article is about how to realize and use localized C:B. All the works have been done under Windows XP SP2.

Get the English POT file

The url of the english POT file is at:

https://translations.launchpad.net/codeblocks/trunk/+pots/codeblocks or

http://www.dlang.net/dl/codeblocks.pot

http://www.dlang.net/dl/plugins.pot

More information can be seen at: http://forums.codeblocks.org/index.php/topic,10204.msg70638.html.

Of course, you can run intl.bat to generate the POT file. The tool wxrc.exe's url is http://www.dlang.net/dl/wxrc.exe.

The content of intl.bat is below:

The tools for translation

Usually, we use the poEdit tool which can be downloaded here. Of course, you can do the translation at https://translations.launchpad.net.

Translating with poEdit

Rename codeblocks.pot into codeblocks.po. Use poEdit to open the file codeblocks.po. Change a few settings like:

[File]->[Preferences]->[Personalize]

[Catalog]->[Settings]->[Project info]->[Team/email/Language/Charset]

If Code::Blocks is compiled with Unicode, the charset should be set to utf-8; If Code::Blocks is compiled with ANSI, the charset should be set to your own language charset like gb2312, koi8-r etc.

After these settings are done, you can start translating. Don't be fooled, it's a hard work! During the process, of course, you can use your translation at any time.

Create and use the .mo file

Pressing Ctrl+S in poEdit, you can get a *.mo file like codeblocks.mo which is what we need. To use codeblocks.mo, we just place it into C:\Program Files\CodeBlocks\share\CodeBlocks\locale\<lang>\LC_MESSAGES or C:\Program Files\CodeBlocks\share\CodeBlocks\locale\<lang>. My language is Chinese and I have installed C::B into E:\, so I place codeblocks.mo into E:\Program Files\CodeBlocks\share\CodeBlocks\locale\zh_CN.

If you want to use codeblocks.mo under Linux or Unix, you just place it into /usr/X11R6/share/locale/<lang>/LC_MESSAGES/. For example, I put it into /usr/X11R6/share/locale/zh_CN/LC_MESSAGES/ under FreeBSD.

Details about internationalization using wxWidgets can be found in the wxWidgets docs.

Let Code::Blocks support your language

If you want Code::Blocks to support your language, you must modify the file \codeblocks\src\src\appglobals.cpp. In it, you can search for the word 'Chinese' to see the example. There are two vars about it:

const wxString langs[LANGUAGES_SIZE]
const int locales[LANGUAGES_SIZE]
