Creating Custom Task Tags [message #1809215]

Should it be a mystery to me why I can't create custom task tags and have my Xtext editor recognize them?

Xtext 2.12 Neon

Is there something I have to enable in the MWE2 workflow to get this enabled or get it added to my DSL preferences?

It seems simple, so I'm confused that I'm confused about it.

is ths about the preference page what the fragment is for or about the tags themselves? which is done via DefaultTaskTagProvider / PreferenceTaskTagProvider which can be customized using normal bindings

I'm using Neon 4.6.3 and Xtext 2.12 and I don't get any Task Tags preferences pages for my DSL by default. Is there a way to add the preference page in Xtext 2.12?

In general, I'm not having any luck adding task tags and getting them to be detected in my DSL files. Perhaps it's only because xtext is searching for its default set. I've tried to add task tags in the Structural Text Editor preferences, but that's not working.

Cool, I've never seen those and can't find them in the docs. Is there a standard way to override them or a blog example somewhere for how to do the bindings/overrides?

I'm not getting any search hits doing a File Search in my workspace for TagProvider - i.e. searching for an existing stub where the binding should occur.

As is aid. You can add the fragment and merge plugin.xml_gen to plugin.xml
There is no example maybe a search on GitHub results in something
I doubt you can add simply a binding to the class to the runtime respectively zu module

Okay, I'll try that. Thank you. What fragment do I add in the generator?

Okay, thanks again. I don't think that class exists in Xtext 2.12. I can't find it with Open Type, File Search, and the MWE2 generator can't find it. I've manually looked through org.eclipse.xtext.xtext.generator packages tried to import org.eclipse.xtext.xtext.generator.ui.* into the MWE2 generator.

Github makes it look like it was there since 2.6. But I can't figure out what qualifier to put in front of it.

fragment = <mystery>..TaskTagPreferencePageFragment2 {}

I might just have to use #FIXME like everyone else. :-)

Which workflow do you use?
The javadoc says it is there since 2.6
Simply use the full qualified name
Also me sure that the plug-in that contains it is on the classpath

PS you can have at the fragment source code and do what it does manually
Or you execute it with 2 18 and copy the generated. Stuff over

Just following up...

This does appear to work in 2.18.

I've added the following line to my MWE2 generator:

 fragment = org.eclipse.xtext.xtext.generator.ui.tasks.TaskTagPreferencePageFragment2 auto-inject {}

Once the generator is run, I merged the contents between the UI project's plugin.xml and plugin.xml_gen files. There was a easily detectable comment <#-- task preference page for <my_dsl> --> that needed to be merged. It adds two extensions to your UI plugin.

Once I did this, the preference page showed up under myDsl preferences and I could add customized tags and have them show up in Task View.

Thanks for the help.

When I first attempt this, I was on 2.12. In that version, I was having trouble resolving the Class path for the fragment in the MWE generator. In 2.18 it wasn't an issue resolving the class path/package for the fragment and it worked out of the box.
