xphp Language Server

Language Server Protocol [partial] implementation that powers editor intelligence for xphp files across any LSP-capable editor:

• diagnostics
• navigation
• refactoring
• completion
• code lenses

The server can be shipped as a self-contained PHAR that can be used by other tools, like IDE plugins.

The server reuses the parent xphp package's AST, generic-instantiation Registry, and TypeHierarchy directly -- no second parser, no duplicated language semantics.

For the public-facing feature inventory plus what's planned next, see roadmap.

---

Install

composer require xphp-lang/language-server

---

Build

make build/phar # → var/xphp-lsp.phar

The PHAR is the distribution format for editor integrations bundle -- zero-config install for editors that can't reasonably depend on a Composer-managed working tree.
