commit d2e5975d27ea2f1c39bddcd5cf2952ffd4ba2039
Author: G. Branden Robinson <[email protected]>
AuthorDate: Sun Mar 2 22:57:37 2025 -0600
[troff]: Implement recursive node dumping (5b/9).
* src/roff/troff/node.h (class diverted_space_node): Specialize
(override) `dump_properties()` for this class.
* src/roff/troff/node.cpp (diverted_space_node::dump_properties): New
member function reports value of `vunits` property.
At present I don't know of a way to get a diverted space node to report
itself in debugging output; the `pline` request works only on nodes that
are in a pending output line, and a diverted space node, being a form of
vertical space (and not "local" vertical motion), exists only between
output lines. Nevertheless this plants a tree today whose shade we
might enjoy later.
