Different spellcheck dictionaries for target and comment text boxes

[rffontenelle]

Is your feature request related to a problem? If so, please describe.

Firefox allows more than language to be spell-checked with its spellcheck dictionaries (going to use "dict" from now on), but uses the only one selected (not all together) per "context". By "context" (which I'm not sure what is, technically speaking) I mean that I can have English set for Weblate and another language for another website (say, writing in issues text boxes in GitHub); but can't have both languages set simultaneously for Weblate.

When translating in Weblate (in Firefox), I rather use my language dict in the translation ("target") text box, and English dict when writing a comment for the source string.

Currently, the dict used in one box applies to the other. So, I have to switch dict if I want the spellcheck to work properly when e.g. I want to write a comment in Weblate.

Describe the solution you'd like

I would like to be able to set a spellcheck dictionary to each of the aforementioned boxes (translation box and comment box), without needing to switch everytime I want to use the spellchecking in them.

Describe alternatives you've considered

No alternatives comes to my mind at the moment.

Screenshots

Here is a screenshot of the Weblate translation editor, showing the translation box with a text in Brazilian Portuguese, flagged as misspelled by Firefox spellcheck feature with English dictionary set, and the commentary box with text in English, not misspelling flag applied:

Additional context

I have no clue how to achieve this. The translation textarea has correctly set language, but that seems to do nothing for Firefox spellchecker.

This issue has been put aside. It is currently unclear if it will ever be implemented as it seems to cover too narrow of a use case or doesn't seem to fit into Weblate. Please try to clarify the use case or consider proposing something more generic to make it useful to more users.

@nijel Can you please point me to the file for the textarea with language set?

[nijel]

It's lang attribute on the textarea:

weblate/weblate/trans/forms.py

Line 299 in 693c389

attrs["lang"] = lang.code

Thanks. Searching for info on firefox+textarea+lang, I found this meta-bag entitled "[meta] Spellchecker fails to honour/remember user's choice of language/dictionary", with some explanation on how Firefox works with lang selecting and some dependency bugs not yet closed: https://bugzilla.mozilla.org/show_bug.cgi?id=1073827#c33

Hope it helps

It all seems to relate to site only, not to individual inputs...

I don't see anything we could do here - the lang attribute on the textarea is set, and it's up to the browser if it will use it or not.
