Is it possible to find keywords positions?

[Artawower]

May I ask why some nodes do not have contentsBegin and contentsEnd? Is this part of the specification? And is there any way to enable this feature?

I'm trying to embellish keywords by range, but now I have to calculate their position by their neighbors. And I have no idea how to do it better.

contentsBegin/contentsEnd are only present in greater elements (elements that contain other elements) and they actually define the range where sub-elements are parsed. Keywords are simple elements (not greater ones), so they should not have contentsBegin/contentsEnd. (This behavior is consistent with org-element.el parsing.)

Though, they should have simple begin/end fields. These are currently missing because they weren't a priority (I focused on getting org->html conversion working and positions aren't useful for that).

If you want to work on that, I am willing to accept this support. It should be relatively straightforward to add: most of parseXxx functions already have begin/end calculated, we just have to add these when calling to u (see packages/uniorg-parser/src/parser.ts); and add appropriate typings in packages/uniorg/src/index.ts.
