# uSCXML ReadMe
uSCXML is a SCXML interpreter written in C/C++. It is mostly feature-complete and
[standards compliant](https://github.com/tklab-tud/uscxml#test-reports) to a large extend.
It runs on <b>Linux</b>, <b>Windows</b> and <b>MacOSX</b>, each 32- as well as 64Bits.
There are still a few rough edges, especially with the plugins and custom extensions.
The latest release will also compile for <b>iOS</b> using the toolchain files in <tt>contrib/cmake/</tt>
it features the (still experimental) JavaScriptCore ecmascript datamodel and no prolog datamodel. I will
work on the Android version as soon as I have some time at my hands.
* <b>Datamodels</b>
* Full [ECMAScript datamodel](https://github.com/tklab-tud/uscxml/tree/master/src/uscxml/plugins/datamodel/ecmascript) using Google's v8 and JavaScriptCore (JSC is somewhat experimental)
* Full [NULL datamodel](https://github.com/tklab-tud/uscxml/tree/master/src/uscxml/plugins/datamodel/null) with required <tt>In</tt> predicate
* Early [Prolog datamodel](https://github.com/tklab-tud/uscxml/tree/master/src/uscxml/plugins/datamodel/prolog/swi) using SWI prolog
* Rudimentary support for [XPath datamodel](https://github.com/tklab-tud/uscxml/tree/master/src/uscxml/plugins/datamodel/xpath)
* <b>Invokers</b>
* <tt>scxml</tt>: Invoke a nested scxml interpreter
* <tt>dirmon</tt>: Watches a directory for changes to files
* <tt>scenegraph</tt>: Simplified 3D scenegraphs with custom markup
* <tt>heartbeat</tt>: Periodically sends events
* <tt>umundo</tt>: Subscribe to channels and publish events
* <b>DOM</b>
* DOM Core Level 2 + XPath extensions available for ecmascript datamodel
* Namespace aware to embed custom markup for special invokers
* <b>Communication</b>
* Features the standard basichttp io-processor
* Features the required SCXML io-processor
* <b>No</b> DOM io-processor
* Can actually respond to HTTP requests with data via <response>
* <b>Language Bindings</b>
* PHP module for apache and cli interpreter
## Test Reports
* We continuously run the [W3C IRP tests](http://www.w3.org/Voice/2013/scxml-irp/) for SCXML.
* Have a look at the [result](http://uscxml.tk.informatik.tu-darmstadt.de/cdash/index.php?project=uscxml) for the various platforms.
* The manual tests are [excluded](https://github.com/tklab-tud/uscxml/blob/master/contrib/ctest/CTestCustom.ctest.in).
uSCXML still fails the following ecmascript tests:
<table>
<tr><th>Test#</th><th>Status</th><th>Description</th><th>Comment</th></tr>
<tr>
<td><tt><a href="https://github.com/tklab-tud/uscxml/blob/master/test/samples/w3c/ecma/test301.scxml">301</a></tt></td>
<td><tt>Failed</tt></td>
<td>"the processor should reject this document because it can't download the script"</td>
<td>uSCXML continues processing as if there was no <tt><script></tt> element.</td>
</tr>
<tr>
<td><tt><a href="https://github.com/tklab-tud/uscxml/blob/master/test/samples/w3c/ecma/test329.scxml">329</a></tt></td>
<td><tt>Failed</tt></td>
<td>"test that none of the system variables can be modified"</td>
<td>uSCXML allows writing to <tt>_event</tt>. This is very useful to have a scope
that vanishes when processing an event is finished. I raised the issue on the ML and it might make it into a later draft</td>
</tr>
<tr>
<td><tt><a href="https://github.com/tklab-tud/uscxml/blob/master/test/samples/w3c/ecma/test346.scxml">346</a></tt></td>
<td><tt>Failed</tt></td>
<td>"test that any attempt to change the value of a system variable causes error.execution to be raised"</td>
<td>Same issue as above: we allow writing to <tt>_event</tt>.</td>
</tr>
