just to clarify: it
worked for the first line, because there is another node before the
first glyph node, so my whatsit is not inserted as the first node of
that list?
Yes. There's a whatsit and the identation box at the beginning of the
first line.
But I don't
see what I'm doing wrong …
To understand what mistake I'm making, I tried to use
letter = node.first_glyph(line) [or line.head?]
instead of the for loop, but then letter doesn't seem to be a node at
all.
That should be node.first_glyph(line.head) (otherwise you browse over
the list of nodes of which the line is part, not the list of nodes which
is the contents of the line). But anyway node.first_glyph only finds
glyph nodes (id 37) with subtype 1 (real glyphs). It's not quite clear
to me what's the difference between a glyph-character (subtype 0) and a
glyph-glyph (subtype 1), but the function is concerned with the latter
only.
So that is ment by “with a subtype indicating it is a
glyph”. Indeed, I thought what I had were glyphs, but appearently they
are not. Do you have a suggestion where I can find information about this?
Apart from Taco's head, I know of no better place to get information
than the manual or your own experiments.
Best,
Paul
