Please note that this repo represents the prototype, proof-of-concept version of Gershwin I wrote to explore the feasibility of the concept.
The Gershwin code base is now maintained as a fork of Clojure in the gershwin/gershwin repository. Please refer to that repository for Gershwin's implementation.
Gershwin is in early development. Take a look at src/main/gwn/gershwin/core.gwn to learn more about the language implementation, or the files under src/main/java/gershwin/lang and src/main/clj/gershwin to peruse the parser, compiler, and runtime infrastructure.
Build Gershwin:
mvn package
Run the executable Jar file:
java -jar target/gershwin-${version}-executable.jar
You can also run a REPL directly:
mvn -Prepl test
For a better REPL experience, I suggest running it through rlwrap or ledit. My personal ledit incantation looks like this:
ledit -x -h ~/.gershwin_repl_history mvn -Prepl test
You can read the in-progress test suite under src/test/gwn/gershwin or take a look at a small example project to see examples of Gershwin code (try this file).
This repository houses a basic Emacs major mode, gershwin-mode, located under support/emacs/gershwin-mode. This mode is derived from clojure-mode and provides some Gershwin-specific syntax highlighting, as well as treating < and > as proper delimiters. Just save the gershwin-mode.el file somewhere on your Emacs load path and add (require 'gershwin-mode) to your Emacs config.
