is there any idf command option to generate cscope.files or compile_commands.json file ? (IDFGH-14559)

[iysheng]

Is your feature request related to a problem?

I always use vim to develop with idf. I found it's hard to jump when view these code. So I wonder is there any command option to genrate cscope.files or compile_commands.json file to achive jump with cscope tool or clangd ?

Hi @iysheng. If you run idf.py reconfigure or idf.py build then build/compile_commands.json should be available in your project. It looks like the Vscode extension also uses it (https://developer.espressif.com/blog/vscode-esp-idf-v1.8.0/#code-navigation-without-full-project-build). Please let us know if this works for you.

I don't think we have support for generating cscope.files right now.

And if you need tips on configuring clangd, please check #6721 for recipes.

tks, I viewed this issue #6721 .
First I do command ln -s build/compile_commands.json . to link build/compile_commands.json file in project root dirctory.
Then I create .clangd file in project root file which has build directory. and add theses content in the .clangd file, now it's ok.

CompileFlags:
  # adjust for your compile_commands.json location
  CompilationDatabase: build/
  Remove:
    [
      -fno-tree-switch-conversion,
      -mtext-section-literals,
      -fstrict-volatile-bitfields,
      -mlong-calls,
      -fno-shrink-wrap,
      -march=rv32imc_zicsr_zifencei,
    ]

Besides, I wonder that though I have set CompilationDatabase: build/ in .clangd file , But if there is no compile_commands.json file in project root dirctory, I still couldn't do function jump.

I found another issue, when I want to jump esp_board_init function defination. I just jump to the function def in the header file hardware_driver/include/esp_board_init.h. How could this happen ?
