c3-lsp is a language server for the C3 programming language.

It provides editor features such as code completion, go to definition,
go to declaration, hover information and signature help. The server can
also resolve standard library symbols for supported c3c versions, so that
completion and hover work across the stdlib.

The server binary is installed as c3lsp and is meant to be launched by an
editor plugin (Neovim, VS Code, Emacs, ...) configured to point at it.
