For spell checking purpose I would like to install an addictional "platform dictionary" in my Eclipse IDE.
You can see the list of platform dictionaries installed in Window > Preferences > General > Editors > Text Editors > Spelling, in the field "Platform dictionary". In my Helios Service Release 1 there are only english of UK or USA. I would to put the language of my country, so I can write comments in my language and have spell check. Eclipse help doesn't explain how.
If you can't find your language word list you can generate one using aspell.
aspell --lang=pl dump master | aspell --lang=pl expand | tr ' ' '\n' > pl.dict
In Ubuntu aspell generates list in UTF-8 in other systems you can add encoding option.
--encoding=utf-8
