node-dyad

primitive language server for node

After getting into more Common Lisp programming, I've realized how nice it is to be able to evaluate files and functions and statements against a live environment, to test out functions and logic incrementally as I go.

There don't seem to be many options available for Node.JS to do this; I tried SwankJS but could not get it working. nodejs-repl.el looks promising! If it works it can replace this code (though this implementation allows any language capable of shelling out to enjoy node interaction too!)

This is a quick hack that gets you a minimal working node repl that you can also send code to.

Caveats

• you need to hit enter twice on the REPL after it starts for it to start working
• no autocompletion on the node REPL

Usage (cli)

npm install --global node-dyad

dyad-server

Starts a node dyad server. Also acts as an interactive REPL.

echo '3 + 4' | dyad-client

Reads javascript code on standard input and sends it to the dyad server to be evaluated. Writes its result to standard out.

Usage (emacs)

dyad-start-server

Starts an async server process containing its own node environment, including an interactive REPL on stdin/stdout.

dyad-eval-current-defun

Evaluates the function the current point is in.

dyad-eval-buffer

Evaluates the entire current buffer.

dyad-run-code

Interactive: prompts you for JS code to be evaluated.
