Zig++ for Neovim

Filetype detection, Vim-regex syntax highlighting, and LSP diagnostics for .zpp files. Pure Lua, no external plugin dependencies. Requires Neovim 0.10+ for the modern vim.lsp.start API.

Install

Build the zpp binary from the repo root:
```
cd ../..
zig build
```
This produces zig-out/bin/zpp.
Make sure zpp is on your $PATH, or pass an explicit cmd to setup.

Add the plugin to your runtimepath. Either symlink this directory:

ln -s "$(pwd)" ~/.config/nvim/pack/zigpp/start/zigpp

Or use a plugin manager. Example lazy.nvim spec:

{
  dir = "/absolute/path/to/zigpp/editors/neovim",
  name = "zigpp",
  ft = "zigpp",
  config = function()
    require("zigpp").setup({
      -- cmd = { "/absolute/path/to/zig-out/bin/zpp", "lsp" },
    })
  end,
}

What you get

.zpp files are recognized as filetype zigpp.
Syntax highlighting (Vim regex, no Tree-sitter required).
The built-in vim.lsp client auto-attaches to zpp lsp on first .zpp buffer. Diagnostics are pulled by Neovim via textDocument/diagnostic (E0001, E0002, E0003, E0004, E0010).

Configuration

require("zigpp").setup({ ... }) accepts:

Option	Default	Description
`cmd`	`{ "zpp", "lsp" }`	Command launched by `vim.lsp.start`.
`root_markers`	`{ "build.zig.zon", "build.zig", ".git" }`	Project-root markers, walked up from the file.

Status

Research-stage. The syntax file is heuristic; the LSP server only implements pull diagnostics — no completions, no formatting, no go-to-definition yet.
