problems with images, layers and crop marks
by Henning Hraban Ramm 08 Jul '19

08 Jul '19

Hi all, I’m quite quiet at the moment, because I can access my mailing list address only via inconvenient webmail; since I updated MacOS, neither Apple Mail nor Thunderbird will take my password anymore... :-(( Besides, I’m currently well paid for working with LaTeX, and my other projects get less time. Anyway, one of our authors finally submitted her final corrections, and "of course" my ConTeXt setup that still worked well in May doesn’t behave any more: * stacked layers won’t work on the first page (there should be a title bar above an image; it works on the back cover, but not on the front; but I can enable one of both layers) That might be related to: * on some right pages, including p.1 (cover), crop marks are shifted one page width to the right. * on some pages, crop marks are shifted vertically; might be related to using \offset for image placement. I’m trying to cook up MWEs, but the behaviour is so strange and irregular, that I don’t know if I can reproduce it in a simpler environment... I suspect my combined use of postponing, makeups, layers and \offset might have grown side effects since May. Any ideas?

crappy names in the fontloader
by Marcel Fabian Krüger 08 Jul '19

08 Jul '19

Hi everyone, under default settings, the fontloaders discards all glyph names which are considered "crappy", meaning matching the "p_crappyname" pattern in "font-oup.lua". For some names this makes a lot of sense. For example the name "uni0303" is considered "crappy" and it really provides no useful information. Then there are other names like "t_uni0303" which are still considered "crappy" while they actually aren't completely useless. So I think there would be some value in preserving them. Of course, you can always enable "otf.keepnames" if you need names like this. But I actually want to talk about another class of names: Look at "Udotbelow". This is IMHO a perfectly normal and useful name, but the fontloader still considers it "crappy" because it starts with a "U" followed by a letter which could be a hexadecimal number. I think this is a bit over-agressive. Maybe the "p_crappyname" pattern could be changed to only look for "u<hexadecimal>" if followed by "p_done", marking the end of a component? Best regards, Marcel Krüger

request for \definefontfamily and \definefallbackfamily
by Pablo Rodriguez 07 Jul '19

07 Jul '19

Hi Wolfgang, I have two requests to be implemented in \definefontfamily. The first one is that is able to load fonts not defined as entries in the font database. Here you have a minimal sample: \definefont[Test][file:texgyrepagella-regular.otf at 10pt] \definefont[TestOne][file:texgyrepagella-regular-500.otf at 10pt] \definefontfamily [mainface] [rm] [Pagella] [tf={file:texgyrepagella-regular.otf}, bf={file:texgyrepagella-regular-500.otf}] \setupbodyfont[mainface] \starttext normal\\ \bf bold not working\\ \Test this works \TestOne this works \stoptext The second one would be to allow method=uppercase to \definefallbackfamily, so it could be used to fake small caps (such as in https://mailman.ntg.nl/pipermail/ntg-context/2018/092878.html. Many thanks for your help, Pablo -- http://www.ousia.tk

feature request
by Atsuhito Kohda 05 Jul '19

I've used LaTeX quite a long time but recently I begin to use ConTeXt too. So I'm very sorry if the following is well-known issue. I find an example of \pmatrix in p.21 of "ConTeXt Mark IV an excursion" (ma-cb-en.pdf). And I notice it is defined in /usr/share/texmf/tex/context/base/mkiv/math-pln.mkiv (in Debian). But it seems \bmatrix, \vmatrix are not defined yet. Is there any reason why they are not defined? Similar commands or environments \begin{bmatrix}...\end{bmatrix}, \begin{vmatrix}...\end{vmatrix} are very often used in mathematical LaTeX documents. It is very useful if we can use \bmatrix and \vmatrix in ConTeXt documents, so please add \unexpanded\def\bmatrix#1% {\left[\matrix{#1}\right]} \unexpanded\def\vmatrix#1% {\left|\matrix{#1}\right|} in math-pln.mkiv or somewhere. By the way, I think it is critical to set \setupmathematics[ampersand=normal] to use \matrix above but I can't find this setting in ma-cb-en.pdf It is great if this is added in ma-cb-en.pdf

I (metapost) can't handle numbers bigger than 32767.99998
by Zhichu 05 Jul '19

05 Jul '19

Hi everyone, I was using metapost to generate some symbols, as in "tex/texmf-context/metapost/context/fonts/mpiv/demo-symbols.tex" Occasionally, I want to customize a glyph whose charcode is a little large, say the character "院": ======================================== ~~~IPython In [1]: for c in u'院': print(ord(c)) 38498 ======================================== so I wrote: ======================================== beginglyph(38498,2,4,0) ; % high voltage interim ahlength := 1 ; drawarrow (1,4) -- (0,2) -- (2,3) -- (1,0) withcolor darkred ; endglyph ; ======================================== and I got: ======================================== ! Enormous number has been reduced. l.60 beginzhglyph(38498 ); I can't handle numbers bigger than 32767.99998; so I've changed your constant to that maximum amount. ======================================== So charcode is a 15-bit integer? Currently, I use `beginglyph(32767,2,4,0) ;` and call it with \char"7FFF. Not an elegant way I think. Is there a fix? I checked the metapost manual and found that charcode is only used to set the filename to something like %{jobname}.%{charcode} I can't see why there's a limit for charcode.

mapping seeregister command to xml
by Thomas A. Schmitz 04 Jul '19

04 Jul '19

Hi, I'm having trouble mapping the seeregister command to an xml setup. Example (looks somewhat messy, but explains why I need it): \startbuffer[test] <document> <p>This is a test. <emph>IGRR</emph> 4, 988<seeinscription sort="IGRR4+988" target="TAM 2 677"><emph>IGRR</emph> 4+988</seeinscription> = <emph>TAM</emph> 2, 677<inscription sort="TAM2+677"><emph>TAM</emph> 2+677</inscription></p> </document> \stopbuffer \startxmlsetups xml:testsetups \xmlsetsetup{#1}{*}{-} \xmlsetsetup{#1}{document|p|inscription|seeinscription|emph|index}{xml:*} \stopxmlsetups \xmlregistersetup{xml:testsetups} \startxmlsetups xml:document \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:p \xmlflush{#1} \par \stopxmlsetups \startxmlsetups xml:emph {\em \xmlflush{#1}} \stopxmlsetups \startxmlsetups xml:inscription \expanded{\inscription[\xmlatt{#1}{sort}]{\xmlflush{#1}}} \stopxmlsetups \startxmlsetups xml:seeinscription \expanded{\seeinscription[\xmlatt{#1}{sort}]{\xmlflush{#1}}{\xmlatt{#1}{target}}} \stopxmlsetups \defineregister[inscription][inscriptions] \setupregister[inscription][pagestyle=, textstyle=, location=right, prefix=none, indicator=no] \starttext \xmlprocessbuffer{main}{test}{} \blank [line] \placeregister[inscription] \stoptext Maybe my problem is with expansion in index entries? I must admit that I haven't really grasped why the \expanded was necessary and what it does... All best Thomas

crosswords puzzles

Dear sirs, Is there a way to make crosswords or word puzzles in context? In my hippocampus I have a vague idea that this has already been tried, but I can't find this code anymore. Have a great day Jorge
