nvim-repl

A lightweight Neovim plugin that opens a REPL (Read-Eval-Print Loop) for the currently attached LSP. Why not using the plugins already available? Because this plugin is 66 lines of code with 30 that I already had for another plugin. It was easier to add the other 36 lines, rather than find and install a new plugin.

Features

• Automatically detects the LSP client attached to the current buffer.
• Opens a REPL (e.g., python3, lua, node) based on the LSP name.
• Configuration:
  • Configurable REPL commands per LSP.
  • Customizable split window position (top, bottom, left, right).

Setup

Use your plugin manager to install and configure:

return {
  "gaiwan-dev/nvim-repl",
  branch = "master",

  config = function()
    local repl = require("nvim-repl")
    repl.setup({
      lsp = {
        ruff = "python3",
        pyright = "python3",
        lua_ls = "lua",
        ts_ls = "node",
      },
      window = {
        position = "bottom", 
      },
    })
  end,
}

The allowed values of position are: bottom, up, left, right. Defaults to left. The RunRepl command is exposed for shortcut configuration:

vim.keymap.set("n", "<leader>rr", "<cmd>RunRepl<CR>", { desc = "[R]un [R]epl" })
