Re: [NTG-context] "Trial typesetting" in ConTeXt / lua ?
Hi Hans
First of all, thanks a lot for replying.
I tried your suggestion and it does not seem to work at least for fancy
features in EB Garamond (historical liguratures and other features).
I also tried to pass the hbox to tex.linebreak() and got assertion failure in
luatex.
Is there any code snippet available to show the full process in lua code (I
mean up to shipping the result nodes to the page) ?
To give some background, I’d like to compute a parshape for some paragraphs for
which I’d like some special shape. I thought that one idea was to build up the
lua nodes from text (which has some occasional words with smaller or different
font style), compute the width of text to figure out a first guess for parshape
and then iterate on linebreak with different parshape settings to refine the
first guess.
Thanks a lot,
Best regards
Joseph

I'm not sure if i understand your issue.
traditional ligaturing and kerning is applied when a node list has fonts
using basemode
\starttext
\startluacode
local hbox = nodes.typesetters.hpack("Hello World!")
context("%p",hbox.width)
nodes.flush_list(hbox)
\stopluacode
\stoptext

you can assemble a list of characters and then do an hpack on them

[NTG-context] just some questions
Hello list. I just have a pairof questions. Could someone point me to the fonts' script used by mtxrun? back in, let's see.. 2011, Mojca replied to Vladimir Lomov, with: > If TEXMFSYSVAR is writable, the cache goes to TEXMFSYSVAR. If it is > not, the cache goes to TEXMFVAR. The idea behind this is that > installer updates the cache when new packages are added, while users > can still generate their own cache. And yes, I even removed the cache file, since it generates itself, correct? I just can't figure out why this problem occurs with the files packed for ubuntu texlive, and I'm almost sure of not having duplicate files, unless I probably missed them, of course! I think I tried all the options available. I know mtxrun script is implemented there as well (in ubuntu texlive). I tried with separate installations first, and finally settled with texlive full, but it made no difference. I know it works in x64 for example, but for some reason, it refuses to follow the exemplary behavior in an i386. (Most of the modules fail or wouldn't find types). And why would ubuntu maintainers have anything to do with it? It's probably my own misconfiguration. But what could be the cause? Thank you in advance, for your time. :) Bye bye Carlos ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___
