ide language

hi everyone

which source file must be change?

I think it was discussed on the Developers List...

If you are using 1.0.3. there is already a translation available, see "Editor language" in the Preferences window. If you think it's not accurate you should contact the developers and suggest your changes. Or you can download the source code from github and look for a file named Resources_fa.properties, make your changes and submit them to the developers.

very very thanks for ur answer spatula i found Resources_fa.properties
how can i edit this file?
which editor must i use?

Any text editor (with unicode support) would be fine. The file is part of the source package, so if you make any changes you'll then have to rebuild the IDE. It shouldn't be difficult if you have knowledge of Java and of its build tools (ant in particular), but I've never done it. I guess that all the properties files are zipped into a jar (I don't know which one), that you can then replace in your IDE directory. There are also the .po files which should be automatically generated by Java gettext. The Arduino website has instructions on how to build the IDE from source.

thx i found .po file n open it n big problem is how can rebuild ide?
