nvim-dap-repl-highlights

Add syntax highlighting to the nvim-dap REPL buffer using treesitter. | Before | After | | --------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------- | | | |

Requirements

• Neovim 0.9 or later
• nvim-treesitter

Setup

Install the plugin and the requirements using your preferred method. Once installed, make sure you have configured treesitter highlighting, then add the following to your lua config

require('nvim-dap-repl-highlights').setup()

After initially setting up the plugin the dap_repl parser needs to be installed, this can be done manually by running :TSInstall dap_repl.

Or automatically through Treesitter configuration:

Using ensure_installed (nvim-treesitter master branch)

⚠️ NOTE: You must call nvim-dap-repl-highlights.setup() before Treesitter, or the dap_repl parser won't be found.

require('nvim-dap-repl-highlights').setup()
require('nvim-treesitter.configs').setup {
  highlight = {
    enable = true,
  },
  ensure_installed = { 'dap_repl', ... },
  ...
}

Using nvim-treesitter.install (nvim-treesitter main branch)

require('nvim-dap-repl-highlights').setup()
require('nvim-treesitter').install { 'dap_repl' }

⚠️ If this ever stops working or the API changes, check the official Treesitter docs for the latest install method:

Usage

By default, the plugin detects the language to use in the REPL by looking at the filetype used to launch dap. Obviously in order to have syntax highlighting for certain languages you will need to have a treesitter parser for that language, alongside the dap_repl parser. This may not fit all use cases.

You could instead use the command :lua require('nvim-dap-repl-highlights').setup_highlights('python') which will set python highlights in the current repl buffer. Alternatively the function can be called without specifying the language, this will prompt the user for a language.

Additionally you could specify in the dap configuration the repl language to use, for example if you want your python repl to have javascript highlighting:

local dap = require('dap')
dap.configurations.python = {
  {
    name = "Python with javascript repl because I like to watch the world burn 🔥🔥🔥",
    type = "python",
    request = "launch",
    program = "${file}",
    repl_lang = "javascript"
  },
}

The repl_lang option takes precedence over the filetype.
