This is an implementation of burn, a light-weight, general-purpose programming language, in Javascript. It is intended as a reference implementation. It is also a relatively painless way to experiment with the language's design.

node --harmony src/bin/burn.js examples/hello_world.burn

There is another, currently outdated implementation of burn at rainbow-alex/burn which will (hopefully) reach production quality some day.

Dependencies

You will need node.js (>=0.10) to run burn.js, with the following modules:

• fibers
• String.fromCodePoint
• String.prototype.at

Python 3 is needed to run the tests.

Implementation

burn.js transpiles burn sourcecode to javascript and evals it immediately. Little effort is made to make this implementation useful or performant.

Tests

The tests in tests/ verify that the core language and builtin modules work correctly. Run them by executing make tests. Other implementations of burn should pass this suite.

The tests in tests_extra/ check additional features that are not required or might differ per implementation. This includes error message details, stack traces, lint messages, ... You can run these tests with make tests_extra. It only makes sense to run this suite for this implementation.

You can run individual parts of either suite with make tests/<path> or make tests_extra/<path>. If you want to run tests against another implementation, use BURN=<absolute/path/to/burn> make ....
