repl

an instant REPL for any command

Features

• Command history (cycle with arrow keys)
• Reverse-search using Ctrl+R
• It's epic

Requirements

• bash
• rlwrap (optional, needed for history)

Installation

Assuming $HOME/bin is in your $PATH,

curl -s https://raw.githubusercontent.com/icyphox/repl/master/repl -o $HOME/bin/repl
chmod +x $HOME/bin/repl

Usage

It's simple, just repl <command>:

$ repl git
git% branch
* master
git% remote -v
origin  [email protected]:icyphox/asdf (fetch)
origin  [email protected]:icyphox/asdf (push)

Or, pipe it to STDIN — repl --stdin <command>:

$ repl --stdin cat
cat% 
yeet
cat% fortnite bad, mc good
fornite bad, mc good

Reverse-search by hitting Ctrl+R:

$ repl pip3
(reverse-i-search)`li': list

And here's repl for ed(1) :)

$ repl --stdin ed
ed% what
?

ed% am
?

ed% i

ed% doing
?
