How does this avoid Cgo? In the case of Ltk (FFI-free, Common Lisp bindings for Tcl/Tk), I know that the library communicates strings to a Tcl interpreter. This means no FFI is involved, but it does mean the user must have Tcl -- specifically, wish -- installed. Is there a similar requirement for this library?

Unfortunately, GitLab is locked behind Cloudflare turnstile and I can't access the source code.
