Proof of Usefulness Score
You're In Business

scheme-langserver is a technically sophisticated open-source project addressing a genuine gap in the Scheme programming ecosystem (lack of robust LSP support). While the project demonstrates high technical innovation through its implementation of static analysis and type inference for a dynamic language, it remains a niche tool with minimal traction (~200 users) and no clear commercial path. The score reflects its strong utility for a small audience but limited broader reach.

Description
This project serves Scheme programmers with language feature supports, including goto-definition, auto-completion, type inference and such many LSP(Language Server Protocol) functionality. Unlike most of counterparts who mainly provide services based on the REPL and the linters, we digest unfinished or still to be polished codes. Now, scheme-langserver is developing its own macro expander so that the users can customize LSP behavior by coding their own macro and without source code altering.
Audience Reach
More than 200 persons used this project by installing VScode plugin Magic-Scheme, and some Helix/Vim/Emacs users also contribute their own configurations. On aspect of
Target Users
This project aims Scheme Programmers and many famous hackers stared it, like Arthur A. Gleckler, who is SRFI's editor.
Technologies
Other, Lisp, Type Inference, Static Analysis
Traction Evidence
Though scheme-langserver published several releases on Internet, we still regard it's pre-official release now. In the near future, we'll enhance its fault tolerance and release macro expander as killing feature to perfectly serve Scheme/Lisp programmers' macro-centered programming.
