Summary

Analyze keywords

Cmacs is a tabbed text editor which can be scripted using the Ccc programming language. It's under heavy development and currently has little practical value as a productivity tool.

The current release is meant to act as an anchor for developers interested in the Ccc language and/or experimentation with the Chrome platform.

Ccc is a Scheme derivative which covers most of the R5 spec while taking some liberties with omissions and extensions.

Cmacs includes a built-in Ccc API for editor manipulation. See the screenshot for an example.

1 stars-its a decent editor, but it really is nothing like emacs. None of the most common emacs bindings are implemented. Having said that- the docs clearly say that this is a starting point and not ready for production use, so fair play.

So, at first I was a bit confused; there's no keybindings for save or open (at least from what I tried). I grabbed the source out of github, and grepped around a bit, then went back to the overview. As far as a playground for the author's dialect of R5RS Scheme goes, this is pretty slick. I think with a few PRs (which I'm interested in poking), this could be a decent emacs-alike for ChromeOS. Rating "4" stars because some of those features like "save" and "open" really should be there prior to calling it much of an editor, but the UI & CCC (the Scheme dialect) work once you get used to it. For anyone trying it: Ctrl (C-) has a number of bindings: C-f is for find, C-h is for replace, C-w is to close a tab, C-t is to open a tab, and C-e is to evaluate a buffer. There are bindings for CCC, and a bet with a bit of elbow grease you could make it into a full-fledged editor write from a buffer (there are FS functions for reading & writing; if those are exposed to CCC you're golden), and I'll experiment with that later. If you like Scheme, seems like a win, and would recommend.
