Cat party

Currently, Cat party is a C parser implemented in Clojure/ClojureScript.

Wait...what?

The eventual goal is to implement a C compiler, implemented in JavaScript (via compilation with ClojureScript), targeting JavaScript. I.e., a C compiler that can operate entirely within a web browser.

Why?

I have a larger goal in mind, but it's too early to say much about it.

How to run it

To run the ClojureScript version, run the command

./scripts/brepl.sh

Then, navigate your web browser to localhost:9000. Then, run the following commands in the REPL:

(require '[catparty.cparser :as cp])
(require '[catparty.prettyprint :as pp])
(pp/pretty-print cp/t)

This prints the parse tree of the test code at the bottom of cparser.cljc.

You can run the same code in a Clojure REPL by running lein repl, and then

(require '[catparty.cparser :as cp])
(require '[catparty.prettyprint :as pp])
(pp/pretty-print cp/t)

What works

Supported features in the C parser are approximately:

• declarations (mostly)
• expressions (mostly)
• statements (mostly)

What doesn't work

• typedef names
• preprocessor (completely nonexistent)
• probably lots of other stuff
