Translation Component

[qoxop]

Hello,
I just looked how to make multilanguage app. I found a translation example in lazarus distribution. I see there is a some drawback with need of manual edit the *.lfm file. Therefore I wrapped the funcionality from "localizedforms.pas" into the component.
- Just put into a form
- Enable i18n in project options
- Edit *.po files
- Call Localize method from component

I found interesting thing. The directory for languages has to be named languages - (in i18n project options).  Other names won't work. (at least for me.... lazarus 1.2.4 - Win7  ?)

And also I have  a question, if droped component on form can somehow modify project Options - Automatically enabling i18n. (To avoid manually enabling i18n in project options)

You can check it in attachment

The details are here, near the end of the section. Respective source in lcl/defaulttranslator.pas, specifically in function GetLocaleFileName.

ah, you are right. Look into the sources gives the right answer. My first impression was the directory name could be whatever. Because in project options you can type whatever you want.

Nice idea to put that stuff into a component!

Feel free to patch it. I guess the current implementation simply follows common pattern in GNU softwares.

I can try to patch it. But what kind of patch do you mean?

1. Patch it in the IDE - Replace current edit box with ComboBox (with predefined  allowed dir names)

2. Or patch the DefaultTranslator to search also for dir names filled by user in Project options - I have no idea if it is possible - To read project options from code (?)

you don't you pass the options to the worker function/class and let it do the rest eg add one parameter called langDirectories of type tstrings or tstringlist and make sure that every using it passes the correct data or nil to use the default only.

I created a patch for DefaultTranslator, because of problem above. (Directory name for *.po cannot be arbitrary). I added overloaded procedure SetDefaultLang

Code: [Select]

procedure SetDefaultLang(LangDirectory: string; Lang: string); overload;  Attached an old and a new DefaultTranslator.pas with diff file
I don't know where to post it, so if someone find it usefull, he can make a patch on svn

Thanks. FYI if you provide the .diff file (and you should unless it's a .po translation file you're updating), please don't/there's no need to provide the old and new pas files.
