Lite XL IDE Setup

Warning

This repository is out-dated. The information stored here will eventually be moved to the new website

Introduction

Documentation for a set of plugins and configuration files that aims to turn Lite XL into a proper IDE.

(This project is still WIP.)

This repository no longer contains an install script to setup Lite XL IDE.

Instead, I am working on adding IDE bundle metapackages to Adam's repo.

This way, if I wanted to install an IDE setup for Java or Python, I could just run one simple command in the terminal, like lpm install ide_java or lpm install ide_python.

With such a command, lpm (Lite XL's own package manager') would take care of installing executable files for LSP servers, linters, formatters and IDE-related plugins.

One thing to keep in mind though, is that at the moment the ideal distribution to use a Lite XL IDE manual setup on is Arch Linux (or a derivative), because all the lsp servers, linters and formatters have a correspondent arch package, either in the official repo or in the AUR.

Installation

Install colors and languages

lpm install meta_colors meta_languages

Install my custom devicons plugin

lpm add https://github.com/PerilousBooklet/lite-xl-devicons.git
lpm install devicons

Install the basic IDE plugins

lpm install ide

or a language-specific ide metapackage: e.g. lpm install ide_c for C/C++ development.

Install some more plugins

lpm install "exec" markers extend_selection_line sort titleize

Install an LSP server

Installation Guide

The LSP servers names can be found in here.

Some other IDE setup steps

Enable automatic linting upon opening and saving a file by adding the following code inside of USERDIR/init.lua:

local lintplus = require "plugins.lintplus"
lintplus.setup.lint_on_doc_load()  -- enable automatic linting upon opening a file
lintplus.setup.lint_on_doc_save()  -- enable automatic linting upon saving a file

Add code snippets by downloading the JSON files from this repo's snippets folder into a USERDIR/plugins/snippets/json folder and then writing the following code inside of USERDIR/init.lua:

local lsp_snippets = require "plugins.lsp_snippets"
lsp_snippets.add_paths {'plugins/snippets/json'}

Allow format-on-save by adding the following code to the init.lua:

config.format_on_save = true
