Out of the box, Sublime Text 3 includes dictionary files to spellcheck U.S. And British English. (See View › Spell Check and View › Dictionary.)
You'll probably want to include additional dictionaries. Here is an example for French, but it should work with any language and I've tested it with success with Hungarian and Russian:
- Download the three
French.*files located here: https://github.com/titoBouzout/Dictionaries - Open Sublime's Packages folder. It's as simple as:
- OS X:
Sublime Text menu › Preferences › Browse Packages…. - Windows:
Preferences › Browse Packages…. - This should open the Packages directory in Windows (Windows) or the Finder (OS X.)
- Copy-paste the files you downloaded to the User folder located there.
The French dictionary should now show up in View › Dictionary › User, ready to use!
