I skimmed the packages source code.

• It ships with a very old version of elixir_sense, it might simply not work with current elixir versions.
• “Linting” seems to only inlcude compiler warnings. Try to_charlist vs. to_char_list, the latter should trigger a compiler warning.
• I can not say anything about the format on save thing. I found that that the setting is mentioned in the “Elixir” plugin, though I can’t say much beyond that.

Instead of the very old “SuperElixir”, have you considered using LSP + elixir-ls (config example). You should probably use a tagged version of the elixir-ls, master likes to break every now and then

Thank you! I tried LSP + elixir-ls and it works great! Even on save format started working properly, don’t really understand why.

I got one last question due to elixir-ls dialyzer integration. Since there isn’t an official plugin for Sublime, how do I enable/disable dialyzer here? Setting elixirLS.dialyzerEnabled to false in LSP client settings doesn’t work.

Cheers!
