The function node.rangedimensions(), when applied to vertical lists, <br>
includes contributions of (vertical) glue nodes in the (horizontal) <br>
width. A simple example:<br>
<br>
-------------------------------------------------------------<br>
\setbox0 = \vbox{<br>
\vskip 10sp<br>
\hrule width 1sp height 2sp depth 3sp }<br>
\directlua{<br>
texio.write_nl (string.format(<br>
'\csstring\%s, \csstring\%s, \csstring\%s',<br>
node.rangedimensions(tex.box[0], tex.box[0].head))) }<br>

<br>
where the fourth line should be 1, 12, 3.<br>
<br>
The cause of this problem seems to be the function natural_sizes() <br>
defined in packaging.c; it looks like it was written with only <br>
horizontal lists in mind.<br>
<br>
This assumption also causes trouble with horizontal rules:<br>
<br>
-------------------------------------------------------------<br>
\setbox0 = \vbox{<br>
\hrule height 1sp width 2sp<br>
\hrule height 1sp }<br>
\setbox1 = \vbox{<br>
\hrule height 1sp width 2sp<br>
\hrule height 1sp width 2sp }<br>
\directlua{<br>
texio.write_nl (string.format(<br>
'\csstring\%s, \csstring\%s, \csstring\%s',<br>
node.rangedimensions(tex.box[0], tex.box[0].head)))<br>
texio.write_nl (string.format(<br>
'\csstring\%s, \csstring\%s, \csstring\%s',<br>
node.rangedimensions(tex.box[1], tex.box[1].head))) }<br>
