Switch between two languages for spell checking in Google Chrome for Mac

Question

Environment: Mac OS X 10.7.2, Chrome 15.

This is how chrome://settings/languages looks like:

When I right click on a text box and go to Spell-checker Options, I get a lot of languages there, but not Croatian.

If at chrome://settings/languages I click Use this language for spell checking for Croatian, then it appears at Spell-checker Options.

But if I switch back to English at Spell-checker Options, Croatian disappears.

I would like to be able to switch between English and Croatian, but I do not know how to set it up.

Answer 1

As can be seen in the implementation of SpellCheckHost::GetSpellCheckLanguages(...), which is called when the menu is initialized, Chrome/Chromium first adds the currently selected spell-checking language to the list of spell-checking languages, and then iterates over the languages available for spell-checking in Mac OS X (implementation here).

Croatian is not one of the latter, as can be seen e.g. in the spell-checking options in Pages:

---

Which languages are enabled for spell-checking on the UI is provided is determined by line 402 here, which is ultimately provided with data from here.

So the issue here is that the two parts of the UI (spell-check context menu and languages selection in preferences) are using two different sets of spell-checkers to determine which languages are supported.

Using that menu to change the language removes it from the list. Unless you're willing to compile your own browser, or file a bug against Chrome on OS X, there's nothing you can do.
