Option to link compile_commands.json to current directory

[ayles]

Would be great to have smth like that

[Civitasv]

This plugin use symlink to achieve that, why not use .clangd?

[ayles]

But switches between release types are initiated by plugin. It is inconvenient to change path to compilation database every time by hand

[Civitasv]

Make sense, I will see how i can implement it.

Something like this in init.lua:125, inside on_success function after running the CMake command. What I can't figure out how to delete the file when exiting the editor.

local compile_commands = config.build_directory.filename .. "/compile_commands.json"
local cmd = "[ -e " .. compile_commands .. " ] && cp " .. compile_commands .. " ."

local handle = io.popen(cmd)
handle:close()

[iFuSiiOnzZ]

Platform independent solution.

Is there any reason to copy it instead of just making symlink?

[iFuSiiOnzZ]

@ayles Because it should be platform independent and I haven't seen anything in the LUA file api that allows to create symbolic links. On Linux you would use ln -s and on Windows mklink.

[Civitasv]

@iFuSiiOnzZ Why not use vim.cmd("term ln -s")?

[Civitasv]

I've added this ability. See 6e4e422

[iFuSiiOnzZ]

Haven't test in on Linux yet. On Windows there are a some problems.

Powershell normal user

CMake Error: failed to create symbolic link 'C:\Users\Develop\Projects\ls/compile_commands.json': A required privilege is not held by the client.

Powershell with admin privileges

:!cmake -E create_symlink cmake_build_Debug/compile_commands.json C:\Users\AndreiAJ\Projects\ls/compile_commands.json

[rohit-kumar-j]

@iFuSiiOnzZ, I did you try compile_commands with MSVC on powershell?

[Civitasv]

Powershell with admin privileges

When in admin privileges, Was the command successful?

[iFuSiiOnzZ]

@rohit-kumar-j I am using mingw, at the moment, so no idea if it works or not.
@Civitasv Nope, I played a bit with Windows policies, but also no luck (Windows 11).

[Civitasv]

Can you show the error messages?

[iFuSiiOnzZ]

For some reason the neovim log is empty and cmake reports nothing about the error.
What is more strange... I ran cmake -E create_symlink from the terminal and it worked.

[Civitasv]

That's interesting.

[Civitasv]

Look at this.
