I'm trying the example from the Readme, but running:
$ rat --mode files --cmd 'ls -al'
..doesn't actually seem to be reading my .ratrc file. The command behaves the same whether I have a .ratrc or not. Is anybody else able to hit enter to preview a file? I'm on a Mac.
Interesting framework. I like the fairly declarative style. The approach to writing terminal applications which interact with shell utilities seems a lot like certain Emacs applications, such as dired.
Emacs Lisp is not a declarative language, of course, but this kind of declarative logic - regular expressions which parse shell command output and apply hidden text properties or keybindings - is common in Emacs. dired does it, as does magit, and all modes based on comint, as well as just normal M-x compile.
