- | E-on-JavaScript is an E implementation which compiles E to JavaScript code, suitable for running in web browsers.

- | The source is currently hosted [https://github.com/kpreid/e-on-javascript/ at GitHub].
| + | |
- | | + | |
- | It was designed to interoperate with [[Caja]], however it is not compatible with modern Caja so the rest of this paragraph is out of date. If cajita.js is also loaded,
| + | |
- | E code can call Cajita-tamed objects; also, the output of the compiler
| + | |
- | should be within the Cajita subset (I have not tested this). However, Cajita code can create objects which violate E [[sameness]] invariants.
| + | |
- | | + | |
- | It is as yet quite incomplete; especially, the compiler does not
| + | |
- | implement all of Kernel-E, and generates inefficient and verbose code.

- | It supports converting an Updoc document, or a HTML document with embedded Updoc, into a HTML document such
| + | |
- | that the tests are executed. [http://www.slimy.com/~kpreid/eojs/serve/vm.html A (stale) example].
| + | |
- | | + | |
- | Not-yet-executed tests have dashed bars to the left, successful tests
| + | |
- | have light gray bars, and unsuccessful tests have red bars and show
| + | |
- | the expected and actual values (which are not differentiated except by
| + | |
- | color; this is to be fixed).
| + | |
- | | + | |
- | As this particular Updoc example was borrowed from [[E-on-CL]], many of the tests fail
| + | |
- | because they are specific to E-on-CL in some way. Many other tests
| + | |
- | fail because in the demonstrated version there was no printing subsystem yet, so everything uses
| + | |
- | JS .toString() and thus the wrong syntax.
