6 Implementing Javascript Modules
Warning: the material in this section is unstable and likely to change.
6.1 Module Implementation in Javascript
This module allows the definition of modules whose implementations
are written in Javascript.
As an example, the following two files provide an implementation
of double in Javascript:
// double.js |
EXPORTS['double'] = |
new types.PrimProc('double', 1, false, false, function(x) { |
return jsnums.multiply(x, 2)}); |
Any module implemented with (planet dyoo/js-vm:1:13/lang/js-impl/js-impl) will provide bindings that require a Javascript context.
6.2 Conditional Module Implmentation in javascript
| (require (planet dyoo/js-vm:1:13/lang/js-impl/js-conditional)) |
Any module implemented with (planet dyoo/js-vm:1:13/lang/js-conditional/js-conditional) can run either in a Racket or Javascript context.
