Can I use multiple spellchecking languages?

[uncommon5012]

Hello! I sometimes write in non-English languages and use some English words and sentences. Is it possible to enable checking for both languages? For example fr and en-US?

You can definitely check more than one language at once. In your VS Code settings (settings.json) add an array to the ltex-plus.language setting, like:

"ltex-plus.language": ["en-US", "fr"]

The extension will then run LanguageTool for each language in the list and merge the results. If you need different languages for specific file types, you can scope it with [languageId] overrides:

"[markdown]": {
 "ltex-plus.language": ["en-US", "fr"]
},
"[latex]": {
 "ltex-plus.language": ["de-DE", "en-US"]
}

I’ve used this setup myself when mixing English code comments with French documentation - works without any extra plugins. Just reload VS Code after changing the setting and you’ll see underlines for both languages. If you run into any odd behavior, check the output channel for ltex-plus to see which language packs are being loaded.
