repl.c
creates a read-eval-print loop out of any command. It is
a simple and readable C program that requires GNU readline.
In other words, it's a REPL for command-line interfaces that always
require a "prefix" command. If you're tired of having to type git
everytime you want to issue a git
command:
$ git init
$ git add .
$ git status
$ git commit
$ git push
$ git status
... then you can do this instead:
$ repl git
git > init
git > add .
git > status
git > commit
git > push
git > status
The program automatically prefixes each command with git
, so that
you don't have to type it.
The following commands install repl
in /usr/local/bin
and
repl.1
, its man page, in /usr/local/man
:
$ make
$ make install
If you want to install it somewhere different from /usr/local
,
edit the Makefile and modify the PREFIX
variable.
To uninstall both binary and man page, run make uninstall
.

repl - create a REPL out of any command
repl command
When invoked, the repl utility puts the user in a read-eval-print loop, in which it reads input from the user, appends it to the command provided by the single argument, and lets the shell evaluate the full string.
Built on GNU readline, it supports history and Emacs key bindings.
repl is useful for command-line interfaces built on a "prefix command" that has to be typed over and over preceding the actual command, like git(1).
