New UserDefinedLang - code fold must begin at margin

gibberishbc

NPP version: 7.7.1
UDL ver 2.1.0.12

I am creating a user-defined-language and am having trouble with the code-folding definitions. Most of the UDL is working great, but it would be great to get the subroutines folding, since I have over a hundred of them.

In this language, subroutines are defined as in this example:

:MySubTitle
code line here
code line here
code line here
Return

I wish to fold between the : and the word Return (the subroutine’s title could be any string of chars). Problem: the concat character is also a colon (:) – and these can be found anywhere in the code. Also, the word Return could be found at other places within a subroutine. If either of these cases is true, the code folding goes completely bonkers – for example if a colon ( : ) character is encountered anywhere inside a subroutine (and since the colon is the concat character, this happens a lot). So basically, I cannot code fold the subroutines – see the screenshot at end of this message).

In this language, note that subroutine :Label / Return are always at the left margin (or indented one tab). In fact, it would be just fine if code-folding required the subroutine start/end to be found at the beginning of the line (not indented at all).

So, is it possible to tell NPP that the code-fold triggers are ONLY valid if found at the beginning of the line (or after some whitespace) ? If not, can this be made into a feature request? Note that I do not have a “Prefix Mode” checkbox anywhere in the “Folding in code N style” groups (“Folder & Default” tab) - see below screenshot.

Afaik, jein, you can, if this is possible on your side, create multiple opens,
to be exact - for each letter an open folder tag like :A :B :C … and fake the
return statement with an added comment tag. This might work.

To address feature requests, see here.

Thanks - good suggestion.

I don’t understand the closing suggestion, though. What do you mean “fake the
return statement with an added comment tag” ? What would that look like, or can you link me to another post that explains?

Many thx !

PS - This question was created/posted yesterday, but I see it is timestamped Oct 7, 2019. Any idea what might have happened? ALSO, I responded (and am now editing) using the Brave browser - and it is working correctly (I see the SUBMIT button so it should save correctly). Ignore my comment from yesterday on my other post (will update)

This is indeed an older thread, your recent threads are others.

As for the fake return statement, assuming a language doesn’t have start and end tokens like if and endif but does have comments, which is the case in most programming languages, you could use the start token if and a end token like #endif, where # is actually a comment.
This way, the language itself is still happy when it is executed, and npp (or UDL) knows where to break.
