LSP server for Objeck

Objeck LSP

LSP support for Objeck was incorporated into v6.0 (and futher releases). Diagnostic functionality (i.e. compiling code, finding symbols, code completion, etc.) is built in libraries that ship with the tool chain. The LSP server is standalone, written in Objeck and exposes STDIO and TCP interfaces. The backend handles client requests, formats responses and maintains the state of in-memory documents.

Please refer to the installation instructions (and issues reports) for editor support.

Work in the Queue

Reviving this effort to provide the following

1. Clean up configuration options
2. Project/workspace build support for non-VSCode clients
3. Better support for Sublime and other text editors (current implementation is based on message ordering from VSCode)
4. STDIO support for Sublime and other text editors
5. Named pipe support for VSCode
