UDL trigger modifiers

[gibberishbc]

I defined my own UserDefLang a long time ago (improving on the WinBatch UDL) and am coming back to it after a couple of years, trying to identify some problems with code folding.

I notice that some of the trigger words have a ^ (caret) after them. For example, subroutines in WinBatch begin with a [ :label ] and end with the word [ Return ]. In fact, the thing that indicates a subroutine is that the first word on that line starts with a [ : ] (colon). So, all WinBatch subroutines look like this -

:Subname
	some code
	lotsa code
	goes here
Return

In the UDL editor, I noticed that these triggers look like this:

Open:
[:^                ]
Middle:
[                  ]
Close:
[Return^           ]

I believe the caret indicates that the trigger word must be the first word on the line. Am I correct? Can there be white space before the trigger keyword?

Where can I find documentation about this? (And I wonder if there are other modifiers that can be used in defining trigger words?)

the official documentation is here and no, a ^ does not mean it has to be the beginning of a line. If you think this has to do with regex, then no, UDL doesn’t support regex yet.

The ultimate truth is in the source.
