c4x -- the neovim compiler explorer

I use godbolt's compiler explorer quite often but copy pasting the code bits over every time is not only cumbersome, its also not recommended to do for proprietary code bases.

Thats why I created this plugin, which allows you to inspect the codegen of files you track. It spawn a panel on the right side of the current buffer which can be navigated left and right. the printing logic is quite naive so if you take more space than the standard 80 characters width it might lead to issues.

Currently it only supports x86-64 gcc (and only the version you have installed locally), changing this to be more dynamic is trivial. the reason I didnt implement it is because I dont need it (yet).

installation

You can git clone the repo and require it. then you can call .setup() and add your prefered keymaps. You can also add an entry to your lazy.nvim plugin list

-- plugins/c4x.lua
return {
  "NuggetOfficial/c4x.nvim"
  config = function() 
    local builtins = require("c4x");
    -- your config here

  end
}

To have everything automatic you can set track_on_enter and open_on_enter to to true in setup({}), otherwise find a nice keybind for at least:

builtin.toggle_asm_panel builtin.toggle_track_current_buffer

planned features

• comparision feature, allowing you to compare codegen of two different files

• git integration, allowing you to compare codegen across branches

• clipped line printing for the tabs in the panel

• generic compiler infrastructure (supporting clang and maybe also cargo or g++)

• command block, that allows you to change the extra compiler flags on the fly.

• asynchronous io so that big compiles dont block the user experience (specially for c++ and rust)

• better modularity for keybinds etc.
