fold code and disclosure triangle TextWrangler

Hello support,

I'm using TextWrangler 4.5.12, the current free release on Mac OS-X. I'd like to be able to insert disclosure triangles in the gutter to control ranges of selected code. The manual offers no guidance, other than to say that these disclosure triangles are autogenerated, and I've searched support forums without success. If I use View >> Fold Selection, I'll get a gray oval with white ellipses in it to indicate folded text. But that's much less useful than the disclosure triangle in the gutter. TextWrangler automatically folds and adds a disclosure triangle inconsistently. Sometimes it will generate a disclosure triangle for a <div>, other times not. When it does not automatically generate a disclosure triangle, I'd like to manually assign one. Do you have any hints on how this can be done?

Thanks,
Enrico

Hi Valentin,

Being able to open and close (fold) sections of code is very useful. I just can figure out how to insert the triangles that you click in order to open or close a selection. TextWrangler generates them automatically, but sometimes it doesn't generate a triangle and I can't insert one. See p. 72 of the manual, attached, where they define "disclosure triangle." (Your system would not allow a PDF attachment; I've attached a JPEG.)



Thanks,
Enrico

Hi Valentin,
I contacted the developers, and here is their clarification:

if a document contains a <div> tag which spans multiple lines:

<div>
foo, bar!
</div>

then TextWrangler will generate a fold range for that tag, whereas it will not fold a <div> tag whose contents are contained within a single line:

<div>foo, bar!</div>

since there's no direct benefit in doing so.
