Siren is an experimental prototype-based object-oriented language. It differs from existing languages in that it uses a single delegation slot for sharing (and cheap instantiation), but allows controlled lexical extensibility.
Getting started
Siren's support for arbitrary-precision arithmetic uses the bignum library, so you'll need to have a C++ compiler and the headers for the OpenSSL library.
Install the Node.js 4.0.0+ (you'll need WeakMaps and Symbols), Make, and
Git. After that clone this repository, and run make compile
. This will
generate a bin/siren
compiler/interpreter, and a REPL bin/isiren
.
$ git clone https://github.com/robotlolita/siren.git
$ cd siren
$ npm install
$ make all
$ bin/siren
You can use the REPL to try out pieces of code interactively:
$ bin/isiren
Type :quit to exit (or ^D).
> 1 + 1
=> <Integer: 2>
You can run individual files with the same binary. There are examples in the
examples/
folder:
$ bin/siren examples/trivial/hello-world.siren
You can compile things to plain JavaScript using the --compile
flag, but
you'll need to pass the proper runtime to the module in order to run it:
$ bin/siren --compile examples/trivial/hello-world.siren > hw.js
$ node -e "require('./hw.js')(require('./runtime))"
Hello, world
