Change of nuts.dimensions function ?
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

Which function should be used now to get natural width of a range [n, t[ of nodes please? i'll check it but if you're on windows you're running the (currently very) experimental version which can actually be broken in some aspects (so you then need to update regularaly)

Hi Hans, Thanks a lot, the function nuts.dimensions seems to work again as before. Another issue I am seeing now is that for some reason the dir nodes push/pop are unbalanced. If I understand the logic of these whatsit nodes they behave like a stack to control the text direction, so I’d assume the number of push nodes and pop nodes is balanced. Currently I see 2 pop for 1 push in shipouts callback (but balanced pop/push nodes in processors callback). If that’s expected from now on I’ll change the logic in my handler. Simple MWE that reproduces is attached.

i get dir=+TRT level=2 dir=-TRT level=1 processor dir=+TRT level=2 dir=+TLT level=3 dir=-TLT level=2 dir=-TRT level=1 shipout dir=+TRT level=2 dir=-TRT level=1 shipout dir=+TRT level=2 dir=+TLT level=3 dir=-TLT level=2 dir=-TRT level=1 (latest experimental ... keep in mind that experimental is *not* really meant for production as it's the branch where we put in code that we work on .. it can even be a temporsary snapshot) (btw, there is a preliminary bidi manual in the distribution which i use when testing some of the low level cleanup in progress)
Thanks
Best regards
Joseph
