Javascript/CSS Syntax highlighting within custom tag [message #529372]

I'm in the process of building a custom tag library that will allow me to include css and/or javascript in any part of a jsp page.

The custom tag will then ensure that all javascript/css spread throughout the page is collated and added to the <head> of the document.
The issue I'm finding is that I can't find a method to inform the jsp editor that the content of my custom tag is javascript or css.

Is there a way that I can force the jsp editor to recognise that content held in a custom tag is javascript or css?

So for example the code could look something like:
<ctag:javascript>
function myFunc(){
document.getElementById("example").style.display="block";
}
</ctag>
<ctag:style>
#example { width:100px; }
</ctag:style>
<div id="example">This is an example</div>

I'm happy to do ground work in enhancing the WTP JSP editor if needs be, just not sure where to start.

Thanks in advance for any help you can offer.

There is currently no way for you to identify the text content of your custom tags as either javascript or CSS.

The way the text in between <style> or <script> tags works is that it becomes a new partition, which the line style providers (syntax highlighting) and content assistants operate off of. So you would more or less need to mimic how the partitioners identify <script> and <style> blocks as their respective partitions.

Check out org.eclipse.jst.jsp.core.internal.text.StructuredTextPartiti onerForJSP, which embeds the StructuredTextPartitionerForHTML. The HTML partitioner is the one responsible for identifying <script> and <style> blocks.

Hi Nick,

I found this post digging into google, trying to find the way to customize syntax highlighting on eclipse.

I think that this discussion treats just the thing that I'm looking for.

I'm trying to define a 'special rule' for allowing javascript highlighting into html files. The question is that I'm using Zend Framework and it is a common practice to embed javascript into the html using these two functions:

<? $this->headScript()->captureStart() ?>

// Javascript code goes here

<? $this->headScript()->captureEnd() ?>

I'm trying to find the file that eclipse uses for load languages definitions and modify it to enable this behaviour.

Is it possible? Is there a file that I can edit for customize syntax highligthing?

Thank you very much for your help!!!

Hi Roberto,

I can't speak for the PDT, but in WTP we don't have any configuration files that you can edit to customize syntax highlighting rules.

You'd pretty much have to do as mentioned earlier.

If this is a common convention, it might be something you could request from the PDT to support.
