Zura Lsp and Syntax Highliter

Zura is a compiled programming language made by @TheSovietPancakes and I. Please check both of us out! :)

NOTE: This is heavily based on [lsp-sample from vscode-extension-samples][sample] with the goal of removing example-specific code to ease starting a new Language Server. NOTE: This was also my version of Jeffrey Chupp tutorial series.

[!NOTE] All files other than zura.vim are for VSCode. Go to Running in Nvim to see how to set up the language server in Neovim.

Running in Vscode

Option A:

1. Download the extension from the VSCode extension marketplace

Option B:

1. Clone this repository
2. Run npm install to install the dependencies
3. Run vsce package to create a .vsix file that can be installed in VSCode.
4. Run from the console code --install-extension zura-lsp-0.0.1.vsix to install the extension globally.

Option C:

If you don't want to install the extension globally, you can open it in its own debug window by running the following:

1. Clone this repository
2. Run these commands:

npm install
cd client
npm install
cd ..

3. Hit F5 on your keyboard or go to the Run and Debug tab and click "Start Debugging" top open the extension in a brand new window.

Running in Nvim

Paste this code from zura-plugin.lua into a file in your ./nvim/lua/plugins directory, for example: ./nvim/lua/plugins/zura.lua

return {
  "neovim/nvim-lspconfig",
  lazy = false,
  priority = 1000,
  config = function()
    -- Filetype setup
    vim.filetype.add({
      extension = { zu = "zura" },
      pattern = { [".*%.zu"] = "zura" },
    })

    -- LSP setup
    local lspconfig = require("lspconfig")
    local configs = require("lspconfig.configs")

    if not configs.zura_ls then
      configs.zura_ls = {
        default_config = {
          cmd = { "/home/thedevconnor/Zura-Transpiled/release/zura", "-lsp" },
          filetypes = { "zura" },
          root_dir = lspconfig.util.root_pattern(".git", ".zura-root"),
        },
      }
    end

    lspconfig.zura_ls.setup({})
  end,
}

Now, place the zura.vim file into your ./nvim/syntax/ directory. It should look like this:

" zura.vim - Enhanced Syntax highlighting for Zura with custom colors

" Define Zura keywords
syn keyword zuraKeyword const fn have auto loop if else return enum struct typename template
syn keyword zuraType int float bool str char
syn match zuraBuiltIn /@\w\+/
syn keyword zuraConditional if else
syn keyword zuraLoop loop
syn keyword zuraStatement return
syn keyword zuraModifier const

" Highlight numbers (integers and floats)
syn match zuraNumber /\<\d\+\(\.\d\+\)\?\([eE][+-]\d\+\)\?/

" Highlight strings (single and double quotes)
syn region zuraString start=+"+ skip=+\\"+ end=+"+ contains=zuraEscape
syn region zuraString start=+'+ skip=+\\'+ end=+'+ contains=zuraEscape

" Highlight comments (single-line and multi-line)
syn match zuraComment "#.*$"

" Highlight structs, enums, and function declarations
syn match zuraStruct /\<\(struct\|enum\)\>/
syn match zuraFunction /\<fn\>\s\+\w\+\ze\s*[(]/

" Highlight operators
syn match zuraOperator /[:=(){}\[\],;.+\-*/<>]/

" Highlight variables (avoid matching keywords)
syn match zuraVariable /\<[a-zA-Z_]\w*\>/ contains=zuraKeyword,zuraType

" Custom colors for Zura syntax (Horizon-style palette)
hi def zuraKeyword guifg=#E95678 gui=bold               " Keywords: Warm pink
hi def zuraType guifg=#25B0BC gui=italic                " Types: Vibrant cyan
hi def zuraBuiltIn guifg=#FAB795 gui=bold,italic        " Built-ins: Peachy orange
hi def zuraConditional guifg=#FAB28E gui=bold           " Conditionals: Muted orange

hi def zuraModifier guifg=#25B0BC gui=bold              " Modifiers: Vibrant cyan
hi def zuraNumber guifg=#E95678                         " Numbers: Warm pink
hi def zuraString guifg=#09F7A0                         " Strings: Soft green
hi def zuraComment guifg=#6C6F93 gui=italic             " Comments: Muted grayish-blue
hi def zuraOperator guifg=#E95678                       " Operators: Warm pink
hi def zuraStruct guifg=#25B0BC gui=bold                " Structs: Vibrant cyan
hi def zuraFunction guifg=#FFD580 gui=bold              " Functions: Light peach
hi def zuraVariable guifg=#FAB                          " Variables: light pink

Afterwards

Assuming you followed the steps above proprely, then as long as you have the Zura compiler installed on your system and in PATH under zura, you should be able to use the Zura language server and syntax highlighter on any .zu file.
