compiler-explorer.nvim

Compile your code and explore assembly from Neovim using the compiler-explorer REST API. Supercharged by vim.ui, vim.notify and vim.diagnostic.

Features • Dependencies • Install • Commands • Configuration

Demo

Preview This is what the interface looks like using the vim.ui provided by dressing.nvim with the fzf-lua backend and the vim.notify provided by nvim-notify.

Features

Compile code asynchronously using vim.loop.
Select compiler interactively using vim.ui.select or pass it as a vim command parameter.
Compile visual selections.
Send compiler warnings and errors to the quickfix list.
Highlight matching lines between source code and assembly.
Show binary output (opcodes and address) using virtual text.
Format code.
Add libraries.
Show tooltips about specific instructions.
Jump to label definitions.
Load example code.
Open the website with the local state (source code and compilers).

Dependencies

You can verify these dependencies by running :checkhealth compiler-explorer

Neovim >= 0.7

Commands

The suggested way to use compiler-explorer.nvim is through the vim commands provided. You can refer to :h compiler-explorer-commands or the table below:

Command	Description	Called from
`:CECompile`	Compile the source code in the current buffer and dump assembly output to a new window. Also accepts a visual selection.	source code buffer
`:CECompileLive`	Same as `:CECompile`, but it will also try to recompile the source code every time the buffer is saved.	source code buffer
`:CEFormat`	Format the source code.	source code buffer
`:CEAddLibrary`	Add a library to be used by future calls of `:CECompile`.	source code buffer
`:CELoadExample`	Load an existing code example to a new tab.	any buffer
`:CEOpenWebsite`	Open the website using the source code and compilers from previous `:CECompile` calls.	any buffer
`:CEDeleteCache`	Clear the json cache where the compilers and languages are stored.	any buffer
`:CEShowTooltip`	Show information about a specific instruction under cursor.	assembly buffer
`:CEGotoLabel`	Jump to the label definition under cursor.	assembly buffer

<details> <summary>Examples</summary>

:CECompile will prompt the user to select the compiler and flags interactively using vim.ui.select and vim.ui.input.
:CECompile compiler=g121 flags=-O2 flags=-Wall specify the compiler and flags as command arguments.
':<,'>CECompile will compile a visual selection.
:CECompile! will open the assembly output in a new window. Not adding bang (!) will reuse the last assembly window.
:CECompile inferLang=false do not infer possible language (based on file extension). Will prompt user to select the language before selecting the compiler.
:CECompile binary=true show binary opcodes and address using virtual text.
:CECompile intel=false use AT&T syntax instead of intel.
:CECompileLive creates an autcommand that runs :CECompile every time the buffer is saved (BufWritePost).

Configuration

compiler-explorer.nvim works out of the box without configuration. If you want to change some of its options (like using a local instance of compiler-explorer), you can do so through the setup() function.

<details> <summary>Default options</summary>

require("compiler-explorer").setup({
  url = "https://godbolt.org",
  infer_lang = true, -- Try to infer possible language based on file extension.
  line_match = {
    highlight = false, -- highlight the matching line(s) in the other buffer.
    jump = false, -- move the cursor in the other buffer to the first matching line.
  },
  open_qflist = false, --  Open qflist after compilation if there are diagnostics.
  split = "split", -- How to split the window after the second compile (split/vsplit).
  compiler_flags = "", -- Default flags passed to the compiler.
  job_timeout_ms = 25000, -- Timeout for libuv job in milliseconds.
  languages = { -- Language specific default compiler/flags
    --c = {
    --  compiler = "g121",
    --  compiler_flags = "-O2 -Wall",
    --},
  },
})
