tree-sitter-poweron

About this project

This is a tree-sitter grammar for the PowerOn Programming Language. While definitetly not complete, it is functional at the moment. Note, I would still consider this in it's beta phase so be aware if you are using this for queries, there may be breaking changes as the project is developed. PR's Welcome.

This project was created primarily for me to use to create a poweron language server that implements the Language Serevr Protocol LSP Documentation

Editor Integration

The process for each editor varies slightly and may require creating a simple plugin for the editor - please check your editor's documentation for tree-sitter integration.

I'm currently using neovim, so I will share what is needed to make this work: 1. Using any plugin-manager install nvim-treesitter/nvim-treesitter. 2. Since this project is not yet available on npm, you'll need to clone this repo somewhere on your machine 3. Add the following to your init.lua or a required file (see my dotfiles repo for an example):

--- Note this section can be whatever you'd like. Check out the nvim-treesitter documentation
require 'nvim-treesitter.configs'.setup {
    inednt = {
        enable = true
    },
           ensure_installed = 'all',
           sync_install = false,
           ignore_install = { '' },
           highlight = {
               enable = true
           },
           autopairs = {
               enable = true
           },
           rainbow = {
               enable = true,
               extended_mode = true,
               max_file_lines = nil,
           },
}

local parser_config = require 'nvim-treesitter.parsers'.get_parser_configs()
parser_config.poweron = {
    install_info = {
        url = '/path/to/tree-sitter-poweron', -- update with path to the cloned repo
        files = { "src/parser.c" },
        branch = 'main',
        generate_requires_npm = false,
        requires_generate_from_grammar = false,
    },
    filetype = 'poweron'
}

4. Create a filetype.lua file in your neovim config directory with the following contents

vim.filetype.add({
        extension = {
        pnd = 'poweron',
        PND = 'poweron',
        po = 'poweron',
        PO = 'poweron',
        pro = 'poweron',
        PRO = 'poweron',
        def = 'poweron',
        DEF = 'poweron',
        sub = 'poweron',
        SUB = 'poweron',
        }
        })

This makes files with the listed extensions be identified as "poweron". This could be updated to use a regex pattern to include something like [1-9]{3}\ to match a .XXX extension. you can also manually set the filetype using

:set filetype=poweron

NOTE: Setting the filetype in lua requires turning it on, so you'll also need to add:

vim.g.do_filetype_lua = 1

somewhere in your init.lua

5. Finally, in order to see the syntax highlighting provided by tree-sitter you'll need to copy the tree-sitter queries from the repo to somewhere in your neovim runtimepath. I have this in my init.lua

vim.cmd[[
    set runtimepath+=~/.config/nvim/queries
]] 

From your terminal prompt run the command:

cp /path/to/tree-sitter-poweron/queries/highlights.scm ~/.config/nvim/queries/poweron/highlights.scm

Of course, for any of this to have an effect, you'll need to be using a colorscheme that utilizes tree-sitter. A good list can be found at https://github.com/nvim-treesitter/nvim-treesitter/wiki/Colorschemes I'm currentl using onedark with the "darker" style
