Re: History Feature issue

[Pierre Gaston]

I'd suggest that you look into the loadable builtin examples in the tarball
and find ideas to write a couple of these.

For instance, you could try to write a Json parser that allows callback and
set some bash variables mirroring the Json in an associative array or
something like that.

There is little documentation so as a result you kind have to look around
in bash source code, and cool builtins could be a way to contribute to bash.

At least that's what I do ( https://github.com/pgas ), even though I have
no real ambition doing this :D
