Evaluate active flag on gcode analyzer AFTER fetching an item from the work queue, otherwise it will always start working once it finds something if the active flag was true once but then switched to false while the queue was still empty.
Thanks to @Salandora for spotting this.
Fixes#357
- GCODE viewer now supports multiple extruders and configurable bed sizes
- GCODE viewer also now based on callbacks and config injection instead of dependence on elements in the embedding website
- Switched GCODE viewer to bootstrap-slider for the layer/command sliders, patched bootstrap-slider a bit up (TODO: PR to upstream)
- GCODE interpreter in backend also calculates filament usage for all extruders
- More consequent use of LESS, switched bootstrap to LESS source to have access to variables and mixins, introduced config setting to switch between usage of compiled CSS (checked in as well) or LESS, defaults to CSS
Changed some endpoints again (removed "/control" path element) and made API spit out only raw data (e.g. seconds, millimeters, unix timestamps etc) instead of formatted versions. Modified frontend to take care of formatting this data itself.
This WILL break existing API clients and probably some event handlers too. I'm sorry for the disruptive changes, but I needed to rectify some decisions before they went too far utilized elsewhere to still be corrected.
Basically this change completely removes the old API and switches it (same endpoint) with the new one, that's basically the existing AJAX API that the client uses, but way more RESTful and based on JSON (exception being the file upload).
The event system has been revamped to carry more payload data (and in an extensible form as dictionary, to allow for later addition of attributes to single events), with the existing event listeners adjusted to also allow users to make use of this data in their consumers.
Documentation has been greatly enhanced for the REST API (and is still being added to), the events will be documented here as well.
Payload data can now be properly injected into event handlers such as command triggers. Added a couple of new events to use for update triggers to the frontend instead of custom code, further decoupling the application. Movie rendering now also causes a frontend notification.
