coderunner

coderunner is a lightweight plugin for NeoVim which enables you to run code in various languages directly from your NeoVim editor. The plugin supports a variety of file types and provides a split terminal window to display the output of your code.

Install

• With packer.nvim

use 'neysanfoo/coderunner'

Setup

The plugin can be configured in lua. Here is a minimal config.

require('coderunner').setup {
  filetype_commands = {
    python = "python3 -u $fullFilePath",
    lua = "lua",
    c = { "gcc $fullFilePath -o $dir/out", "$dir/./out" },
    cpp = { "g++ $fullFilePath -o $dir/out", "$dir/./out" },
    java = { "javac $fullFilePath", "java -cp .:$dir $fileNameWithoutExt" },
    javascript = "node $fullFilePath",
    -- add other filetypes and their corresponding run commands here
  },
  buffer_height = 10,  -- height in lines
  focus_back = false   -- whether to set the cursor back to the original window after running the code
}

To create your own filetype_commands, simply add a key-value pair to the filetype_commands table in your setup configuration. The key should be the filetype (like python, c, cpp, etc.) and the value should be the command you want to run for that filetype. The command can use the placeholders $dir, $fullFilePath, and $fileNameWithoutExt which will be replaced with the directory of the file, the full file path, and the file name without extension respectively.

Commands

• :Run: Runs the current file. It pulls the associated command from your filetype_commands configuration. The command is run in a new split window at the bottom, allowing you to view your code's output within NeoVim. If focus_back is set to true, the cursor automatically returns to your original file. The output split can be closed by typing either :q or q in normal mode, or any key in insert mode after the process has exited.
