commit 4c586f362787b23dffbf32754e17a8a6748ee9be
Author: G. Branden Robinson <[email protected]>
AuthorDate: Mon Mar 3 07:44:02 2025 -0600
[troff]: Implement recursive node dumping (5p/9).
* src/roff/troff/node.h (struct width_list): Declare `dump()` member
function.
(class word_space_node): Specialize (override) `dump_properties()` for
this class.
* src/roff/troff/node.cpp (width_list::dump): New member function
traverses a singly-linked of `width_list` nodes, and reports values of
`width` and `sentence_width` properties.
(word_space_node::dump_properties): New member function reports values
of `width_list` (if not a null pointer) and `unformat` properties.
Changes `pline` request output as follows.
-{"type": "word_space_node", "diversion level": 0, "is_special_node":
false, "hunits": 2500}]
+{"type": "word_space_node", "diversion level": 0, "is_special_node":
false, "hunits": 2500, "width_list": [{ "width": 2500, "sentence_width": 2500
}], "unformat": false}]
