clang-tidy -export-fix

[Altyrost]

I'm trying to replace in QtCreator the invocation of clang-tidy with clangd-tidy because it's really faster.

In the standalone clang-tidy, there's a -export-fix that exports a yaml file looking like this:

---
MainSourceFile:  '/project/path/src/main.cpp'
Diagnostics:
  - DiagnosticName:  modernize-use-trailing-return-type
    DiagnosticMessage:
      Message:         use a trailing return type for this function
      FilePath:        '/project/path/src/main.cpp'
      FileOffset:      501
      Replacements:
        - FilePath:        '/project/path/src/main.cpp'
          Offset:          497
          Length:          3
          ReplacementText: auto
        - FilePath:        '/project/path/src/main.cpp'
          Offset:          507
          Length:          0
          ReplacementText: ' -> int'
    Level:           Warning
    BuildDirectory:  '/project/path/build/Desktop_Qt_6_8_2-Debug'
...

Is there a way to generate that with clangd-tidy ? If not, could you give me pointers about how to implement it myself ? (I have no experience with LSP)

Thank you for the feedback!

Yes, this should be technically feasible. I can obtain some TextEdit objects from LSP by requesting a codeAction. However, I haven't tested it yet, so it may or may not work. Additionally, when multiple code actions are available at once, it's hard to predict how they will interact.

This could be a potential feature for v1.2.

I had a similar need. In my use-case it was specifically for fixes of naming convention violations, with code actions that span possibly across multiple files for a single edit (such as function renames in header files and all call sites). I've made a PR for it: #27
