User Defined language more folding in code styles

[denwitham]

I have writen a user defined Language highligher using the built in editor
Language > User Defined Language > Define your language

how do you do more than two folding code styles and one comment folding style ?

My language has at least 3 if, foreach and switch and has a multiline comment fold style

I have tried editing the xml and adding in
<Keywords name=“Folders in code3, open”>Switch:</Keywords>
<Keywords name=“Folders in code3, middle”>Case:</Keywords>
<Keywords name=“Folders in code3, close”>EndSwitch:</Keywords>
but that just gets ignored / removed

Additionally how do you add more than one middle ?
e.g.
if / elsif / else / endif
switch / case / default / endswitch

You cannot just add new structures in the UDL XML definition and hope that Notepad++ would just magically understand what you meant.

You can mix multiple fold structures of the same type in the same boxes.

Folding in Code 1 is meant for things that fold that don’t require spaces surrounding it – so the c-style { … } folding would be a primary use case for FiC1.

Folding in Code 2 is meant for things that fold that do require spaces, like words, so that it will fold on “if” but not “gif” or “iffy”. So if / else elsif / endif would be one such set.

Folding in Comments is intended as a way to add a prompt inside a comment that will do folding. for example, =begin and =end as FoldingInComment with comment prefix of #:

With multiple in the same box, like the if and switch constructs, you could technically trick N++ into doing folding on invalid combinations, like if / case / endswitch or switch / else / endif . So it’s imperfect, but N++ UDL isn’t meant as a code validator, and won’t enforce valid syntax.

But since most languages require fully nested, most combinations will fold the way you expect:

You will notice that I earlier had a space between the default and the :, because in FoldingInCode2, spaces are required. If you moved it over to FoldingInCode1, then you wouldn’t need that space:

@PeterJones Thank you, just what I was looking for.
