@llvm/pr-subscribers-clang-tools-extra Author: Richard Li (chomosuke) ChangesFor some other lsp / linters. They will offer a "Ignore this error for this line" code actions for warnings. I find that convenient as I don't have to type the comment myself and copy the name of the diagnostics. This is the first time I work on such a large code base so any feedback and guidance are greatly appreciated. Patch is 32.58 KiB, truncated to 20.00 KiB below, full version: https://github.com/llvm/llvm-project/pull/114660.diff 13 Files Affected:

For some other lsp / linters. They will offer a "Ignore this error for this line" code actions for warnings. I find that convenient as I don't have to type the comment myself and copy the name of the diagnostics.
This PR implements this for clangd. For all diagnostics from clang-tidy, this PR adds an extra quick fix to insert a
// NOLINTNEXTLINE(diag-name)to suppress the diagnostics.This is the first time I work on such a large code base so any feedback and guidance are greatly appreciated.
