vedis bash loadable

what is this?

Loadables in bash are exactly like builtins, but you enable or disable at runtime. They're shared libraries whose main interface is receiving the WORD_LIST, which is basically the last command.

For this loadable, I want to provide nice data structures directly to bash.

Vedis is an embeddable self-contained library with commands and data structures from Redis, but without the networking.

RbStringIndices

What is this?

rb_string_indices is a rust native extension for ruby String that returns all indices for matches of a given substring.

How does it work?

It's using a ruby and rust interop library called rutie.
