I am trying to define an empty patter group in the DefaultState, ie.

<ExplicitPatternGroup Token="UserCustomToken" Style="UserCustomStyle" LookAhead="{NonWordMacro}"/>

I basically want to leave the pattern empty and have it as a placeholder that I can load in patterns at runtime based off of user supplied information, in this case a database query to retrieve pattern items.

However, when I load the language it complains about not having any patterns. Is there a way to create a "placeholder" pattern group?

Thanks

Unfortunately it does require a pattern in the def. Although you MIGHT be able to stick something in there and then at run-time remove the pattern from the group after you load the language. That is untested but may work.

Yeah, it has to have a pattern and I found it has to have at least 1 pattern when you call IsUpdating=false or you get the same error.

I just created a single pattern that is the name of the pattern token and use that since that should never be used.

Thanks
