Here you can see there's code completion in Visual Studio for Kendo UI components, together with documentation showing you the options you can add to the argument object.
Displaying the classes in code completion (i.e., IntelliSense) in NetBeans is already supported, if you check out the sources of Kendo UI from its Git repository and put them into your HTML5 project in NetBeans. NetBeans will then detect the sources that you have added, which you can of course exclude from your Git commits, and then display relevant proposals in the code completion box:
However, I'm also working on a plugin that shows, context sensitively, the options available for the current Kendo UI component. Here you see what happens when I call up code completion for KendoCalendar:
And here, to show you that each Kendo UI component is supported via its own set of options in code completion, is what you'll see for KendoAutoComplete:
How it works is that the plugin will contain all the documents from the Kendo site, such as this one:
These are then parsed and integrated into the code completion box in NetBeans. In other words, all the code completion and related documentation will come from the Kendo UI site, i.e., they will be copied into the NetBeans module and used from there. Indeed, if they change on-line, there'll be no way of knowing that, plus the authors of those documents possibly don't treat them completely as an API, which is how I am treating them. Unfortunately, I don't see a better way of doing this.
I'm not parsing completely correctly yet, hence some of the options are clearly missing from the two screenshots above. Once everything is working as it should, the documents will be read from the layer.xml file, meaning that anyone will be able to add new ones to their user directory and NetBeans will automatically pick it up, e.g., when a new Kendo UI component is made available, together with its documentation.
Soon the first draft of the plugin should be available and it will be developed on GitHub, so anyone out there is free to join in:
