プロジェクトの歴史

PureScript Language Server was developed as a Node-based LSP wrapper around the IDE server included with the PureScript compiler, historically known as psc-ide and now invoked through purs ide server.

The project broadened compiler IDE functionality into standard LSP features, including completion, definitions, hover information, symbols, diagnostics, code actions, import fixes, case splitting, and formatter integration.

採用の歴史

The server was originally consumed by VS Code and Atom integrations but was designed around the editor-neutral Language Server Protocol. Its README documents use with Neovim, Vim LSP clients, Coc, and other clients supporting stdio, sockets, pipes, or Node IPC.

Its practical adoption follows the PureScript toolchain: projects commonly combine the language server with the purs compiler, Spago sources and builds, and an external formatter.

使われ方

Editors launch purescript-language-server with a transport such as --stdio and send purescript.* settings through LSP configuration. The server locates the compiler and project tooling, starts purs ide server, reports diagnostics, provides navigation and completion, and invokes a configured external formatter.

Configuration is client-supplied through LSP initialization or workspace configuration, with a JSON --config option as a fallback; upstream does not document a standalone configuration-file location.

パッケージ好きにとっての重要性

The package separates PureScript editor intelligence from any single editor. This lets package-manager users install one backend executable and connect it to many LSP clients rather than relying on editor-specific implementations.

It also illustrates a common language-tooling architecture: an LSP adapter wraps a compiler-owned IDE protocol, delegates builds to the compiler or package tool, and delegates formatting to specialized formatters.

タイムライン

• Undated: The project wrapped psc-ide/purs ide server in the Language Server Protocol.
• Undated: Support expanded beyond its VS Code and Atom backends to general LSP clients.

Related projects

• The server starts and communicates with purs ide server. It can add Spago dependency sources, run configured builds, serve VS Code and other LSP clients, and delegate formatting to purs-tidy, pose, or purty.
