Hello all, It seems that with latest ConTeXt beta (with luatex 1.07.0) it seems that nuts.dimensions function behaviour has changed. Simple MWE shows the change. Which function should be used now to get natural width of a range [n, t[ of nodes please? Thanks a lot Regards Joseph Canedo \startluacode local nuts = nodes.nuts local getdimensions = nuts.dimensions local tonut = nuts.tonut local tonode = nuts.tonode local tasks = nodes.tasks function handler(head) head = tonut(head) print('Width=' .. getdimensions(head, head)) // used to be 0 (as per luatex doc), now it’s most likely the natural width of the box. return tonode(head) end tasks.appendaction("processors", "after", "handler") tasks.enableaction("processors", "handler") \stopluacode \starttext Foo. \stoptext
