REPL Client (rc)

REPL Client (rc)

REPL client with tab completion and history. A simple, npm installable alternative to netcat (nc) and socat.

Install

npm install -g repl-client

Usage

$ rc /tmp/repl/socket.io.sock

Adding a REPL to your app.

To easily add a REPL to your Node.js app, use replify.

Compatibility

repl-client only works under node 0.10. Upgrade.

Use cases

As a repl

rc /tmp/repl/hello.sock
hello> require('os').type()
'Linux'

Using stdin pipe

echo "require('os').type()" | rc /tmp/repl/hello.sock
hello> require('os').type()
'Linux'
hello> %

Props

• Special thanks to @TooTallNate for all the work he's done in improving node's REPL.
• The starting point for this module was Nate's "full featured" REPL client: https://gist.github.com/2209310
• We have been using this at @Voxer and love it.

repl-client's Issues

exit using CTRL-D leaves STDIN in raw-mode

One possible fix might be:

name of the executable

This tool is nice. We use it at work. A now departed colleague set it up.

However, not knowing that and seeing that 'repl-client' was never referenced in the code, I suppressed the dependency.

A month later, we struggled to understand to what some rarely-used production procedures were refering to while trying to access the cryptic rc...

A search of "node rc" on google returned a LOT of misleading stuff.

I humbly suggest to rename "rc" to "repl-client" to avoid such confusion. It would be clearer and coherent with the package name. 9 chars is nothing compared to precious time wasted.

Thanks !

Doesn't work for Node 0.10.x
