Jim

Though the contents of https://github.com/antirez/jim dates from 2009, Jim Tcl is actively maintained. You'll find the official GitHub mirror at https://github.com/msteveb/jimtcl. Edit: If this subthread got you interested, antirez's other Tcl projects are worth checking out. They are listed on his page on the Tcler's wiki: https://tcl.wiki/9497. I particularly recommend https://tcl.wiki/Picol, the tiny predecessor to Jim Tcl, and https://tcl.wiki/Sugar, a macro system for Tcl 8.4+. Disclosure: I maintain a somewhat larger fork of the former.

That there was no Tcl implementation for the CLR? Can we not just build cool things? Sorry, I could not help myself. Fun fact: antirez of Redis fame started with an interest in Tcl, and he has written about it. He wrote his own minimalist Tcl implementation in C, despite the original being an exemplary C project (or so I have heard the Tcl codebase is still sometimes used, despite reservation about the resulting language here, as a very clean and easy learning object for teaching language/interpreter design) and I doubt none of his experiences or lessons learned bled into the uber-success that Redis now is, right? http://antirez.com/articoli/tclmisunderstood.html https://github.com/antirez/jim
