Search history with buffer on pressing arrow key

[tiye]

It's a feature in Boot REPL. I don't know what to call it but I use it for long. For example I got some histories:

(+ 1 2)
(+ 2 3)
(- 2 1)
(- 3 2)

Now I typed (+ in the REPL and use Up key to find history. Currently I got any history one by one. But in Boot, only (+ 1 2) (+ 2 3) are matched since the beginner characters are the same.

I'm considering it as a new feature we need.

Wow neat, you made me discover this feature in boot repl 😁

@arichiardi I'm using this features for years in Bash:

=>> cat ~/.inputrc
"\e[A":history-search-backward
"\e[B":history-search-forward

set show-all-if-ambiguous on
set completion-ignore-case on

If we're going to do something similar, I would probably prefer implementing something like Planck's new reverse i-search feature.

@jiyinyiyong Thoughts?

[tiye]

Well, I think history-search-backward is easier to implement since we only need to test with start-with?. reverse i-search would be fine. But I have to say personally I never used Ctrl R in real my work.

I think I prefer reverse-i-search since it's more standart across shells, more people will know about it instinctively. It's also more powerful.

I can also find the up behavior a bit intrusive. Reber i search is more optional.
