basex-lsp/README.md

Work in progress.

An attempt to write a Language Server Protocol server using XQuery 4.0 and the BaseX websocket feature.

Server

• webapp/lsp The LSP implementation in XQuery using WebSockets for transport and the JSON-RPC 2.0 API for format.

Sample clients

• webapp/static/codemirror A test html page using the CodeMirror6 editor that connects to the BaseX LSP instance
• webapp/static/ace A test html page using the Ace editor that connects to the BaseX LSP instance

Uses

• https://github.com/mkslanc/ace-linters https://mkslanc.github.io/ace-linters/

• I needed set NODE_OPTIONS=--max_old_space_size=8192 for build to complete

• or node --max-old-space-size=8192 node_modules/webpack-dev-serve r/bin/webpack-dev-server.js
