AutoHotkey v2 configuration for thqby's lsp using nvim-lspconfig

There may be a better way to do this without manually placing the server configuration in lspconfig's plugin folder, but this is what I've got and it does work, so...

Follow the instructions from thqby's extension README to download/install the language server and place it wherever you want it to stay. If you already have an existing installation, the minimum version required is 1.9.1 (unless you have a really old version)

First, find the plugin folder for lspconfig.

For me, this is at C:\Users\%USERNAME%\.local\share\nvim-data\site\pack\packer\start\nvim-lspconfig but the default location on Windows, using Packer, is %LOCALAPPDATA%\nvim-data\site\pack\packer\start\nvim-lspconfig

The nvim-lspconfig folder will most likely be a descendant of %LOCALAPPDATA\nvim-data\site\pack with windows and ~/.local/share/nvim-data/site/pack with Unix. Mine is also under packer\start since I installed it with Packer. You just have to find out where your plugins are installed according to your package manager.

Next, the nvim-lspconfig\lua folder is where you want to be. Inside this folder, you've got:

.\lspconfig\
    server_configurations\
        als.lua
        anakin_language_server.lua
        angularls.lua
        ansiblels.lua
        ...
    ui\
        lspinfo.lua
        windows.lua
    configs.lua
    util.lua
.\lspconfig.lua

lspconfig uses the files in the server_configurations folder to provide setup functions. The name of the file in server_configurations is what you use to retrieve the function in your lua code:

require[[lspconfig]].<filename>.setup()

Add a new server configuration

You can just drop ahk2_ls.lua in nvim-lspconfig/lua/lspconfig/server_configurations. But you may want to go ahead and change some values here so you don't have to do it when you call the setup function. This is just creating a default configuration so that lspconfig will provide a setup function. There are some options for formatting, comment tags, which libraries to auto-include, etc. There are comments and annotations in the ahk2_ls.lua file provided; just give it a look.

---

Call setup function

I like to create wrappers for my plugin setup functions. So I have something akin to what's in the lspconfig_setup.lua file. If you placed it in nvim/lua, then in your nvim/init.lua, you'd just need to add:

require'lspconfig_setup'.setup_ahk2_ls()

The reason I make a wrapper for it is so I can require my setup file and make changes to the setup options before I call the setup function, just in case I want to change something from my init.lua instead of the required file, eg. »

local lspconf = require'lspconfig_setup'
lspconf.ahk2_setup_options.init_options.FormatOptions.max_preserve_newlines = 3
lspconf.setup_ahk2_ls()

It's totally unnecessary though, so you know, adapt it to fit your own configurations.
