[MythreyaK]

To track various issues

• • Rename symbol doesnt rename symbols accessed via c++23 'deducing this' clangd/clangd#2323
• • Code completion incorrectly inserts placeholder for explicit object parameter clangd/clangd#2339
• • Signature help popup should not contain the explicit object parameter with "Deducing this" clangd/clangd#2284
• • [Clang] Incomplete/incorrect code completion about explicit object member function #109608
  • • Missing autocomplete suggestions for deduced-this methods called with this->
  • • Unexpected self argument in autocomplete
  • • (Related) Snippet suffix and signature incorrect for (&A::foo)(a) usage --- self parameter should be inserted
• • [clangd] In the body of a function with an explicit object parameter, code completion suggests members without accessing them through the object parameter #141291

Thanks for filing, and for the work you've been doing in this area!

• • Rename symbol doesnt rename symbols accessed via c++23 'deducing this' clangd/clangd#2323

This is related to "deducing this", but not to code completion. I think we should either drop it from the list, or broaden the issue title to "clangd support for 'deducing this'".

• • Unexpected self argument in autocomplete

I think this was fixed by clangd/clangd#2339?

broaden the issue title to "clangd support for 'deducing this'"

Sounds good!

Yep, updated, my bad.
