MetaPost label direction prefix
by Marco Patzer 25 Aug '13

25 Aug '13

Hi, what is the reason the label direction prefix variables (rt, bot, llft, etc.) are prefixed with mpfun_ in MkIV (mp-mlib.mpiv)? When new directional prefixes are being defined it fails when mplib is used unless the mpfun_ prefix is added. And likewise, code using the mpfun_ prefix fails on traditional MetaPost. Is this prefix required? It breaks old code and required a branch in every new project. And I don't really see a reason for this incompatibility. Here is an example defining a new direction “foo”: \starttext \startMPcode label("first", origin); %% MkIV %% pair mfun_laboff.foo ; mfun_laboff.foo := (.5,-1) ; %% mfun_labxf.foo := mfun_labyf.foo := 1 ; %% MkII pair laboff.foo ; laboff.foo := (.5,-1) ; labxf.foo := labyf.foo := 1 ; label.foo("second", origin); \stopMPcode \stoptext Marco

section headings on a grid: less space above?
by Lars Huttar 24 Aug '13

24 Aug '13

Hello, I'm using mkii to typeset a document with grid layout. I'm trying to configure the formatting of the subsection headings. I have the following setuphead: \setuphead[subsection][number=no,style={\switchtobodyfont[SansB,\subheadersize]},grid=top] This works successfully in that the lines below the heading are aligned to the grid. But what I'm trying to change is the fact that 4 grid lines are taken up by the heading: approximately two blank lines above, and one below. The requirement is to use 3 grid lines. I know how to move the heading text down within the space: grid=3pt does that. But I can't figure out how to reduce the number of lines above the heading text. The document at http://www.pragma-ade.com/general/manuals/details.pdf says that the "top" option (as in grid=top) means "add/remove an extra line to the top". But in my experimenting, the presence or absence of "top" seems to make no difference. I also tried: grid={broad,low} grid={fit,low} grid={line,3pt} grid=standard no "grid" setting at all but none of these seems to reduce the total amount of vertical space taken up by the heading. Can somebody tell me how to do this? E.g. how to make the "top" option "remove an extra line" on top? Thanks, Lars P.S. version: ConTeXt ver: 2008.05.21 15:21 MKII fmt: 2009.1.20 but I'm hoping the oldness of the version isn't a factor here.

Cyrillic replacement for TeX Gyre Schola?
by Henning Hraban Ramm 24 Aug '13

24 Aug '13

приве́т! My songbooks are typeset in TeX Gyre Schola (since Century Schoolbook is the default lyrics font of LilyPond, I like it and it’s very readable). Seems like I didn’t need Russian lyrics since the removal of Cyrillic glyphs from TeX Gyre. But now I do. What would you do? Is there an illegal "complete" version around, or can you suggest a replacement (and tell me how to setup ConTeXt to take that font for all Cyrillic letters)? Greetlings, Hraban --- http://www.fiee.net/texnique/ http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)

Typesetting Classical Arabic Poetry
by J. R. Schmid 24 Aug '13

24 Aug '13

Dear list, for better or worse, I'm trying to typeset Arabic poetry in ConTeXt after having become fed up with LaTeX for a variety of reasons. Arabic script itself is not a problem and I already love how easy it is to use whatever font you like and how clean ConTeXt seems to be in its design. What is giving me trouble, though, is the face that traditionally, poetry needs to be typeset in two columns. Using an English poem for an example, it'd look a little bit like this: Said Rich Accetta-Evans: 1 My poem delights me 2 My poem is mine 3 It is like fresh bread 4 When I bake it myself 5 It is like my son 6 The day he was born [...] This is to be read in the order of the numbers, so "columns" or "simplecolumns" won't work (I think). The second problem is the way in which Arabic needs to be justified, namely not by adjusting the space between words, but instead by adjusting the connecting line between letters: قال أبو الطيب أحمد بن الحسين المتنبّي أنـا الـذي نـظر الأعمى إلـى أدبي وأسمعـت كـلماتــي مـن به صمم كم تـطلبون لـنا عيبًـا فــيعجزكم ويكره المجد ما تأتـون والكرم ما أبعـد العيب والنقصان عن شرفي أنا الثّريا وذان الشيب والهرم [...] I couldn't find any info on either of these two questions through the documentation or through Google (although I might have been looking for the wrong keywords). Any comments are appreciated! :-) With best regards, J. R. Schmid

Hi, Some new magic in the beta ... \setupbodyfont[pagella] \starttext \setupindenting[medium,yes] \setupalign[tolerant] \definefirstline [fancy] [alternative=line, color=darkred, style=\setfontfeature{smallcaps}] \setfirstline[fancy] \input tufte \par \setfirstline[fancy] \input ward \par \setfirstline[fancy] \input knuth \par \setfirstline[fancy] \input bryson \page \definefirstline [fancy] [alternative=word, color=darkblue, style=bold, n=2] \setfirstline[fancy] \input tufte \par \setfirstline[fancy] \input ward \par \setfirstline[fancy] \input knuth \par \setfirstline[fancy] \input bryson \page \stoptext (Actually, it was rather old magic that I found back in an "early days of mkiv" file).

LuajitTeX fails to load font

23 Aug '13

Hi, the following example compiles fine with LuaTeX, but LuajitTeX fails to find the font. \setupalign[r2l] \definefont[Sheherazade][name:scheherazade*arabic at 18pt] \starttext \Sheherazade أهلا بالعالم! \stoptext fonts > defining > font with asked name 'scheherazade' is not found using lookup 'name' fonts > defining > unknown font 'scheherazade', loading aborted fonts > defining > unable to define 'scheherazade' as 'Sheherazade--0' The font is in the font database and regular LuaTeX succeeds. mtxrun --script fonts --list -all scheh scheherazade scheherazade /home/marco/.fonts/scheherazade/ScheherazadeRegOT.ttf scheherazadenormal scheherazade /home/marco/.fonts/scheherazade/ScheherazadeRegOT.ttf This might be related to the thread from a few days ago: http://thread.gmane.org/gmane.comp.tex.context/83871/focus=83877 Marco PS: The font can be found here: http://scripts.sil.org/cms/scripts/render_download.php?format=file&media_id…

Hidden sections
by Mikoláš Štrajt 23 Aug '13

23 Aug '13

Hello all, We are writing a magazine with my friends and I am going to typeset it with ConTEXt. It works fine but I ran into the problem with heads. In our magazine articles will be grouped in sections (e.g. poetry, short stories, programming). I need to hide section heads in text but to show them in TOC and page headers. So there will be no „Poetry“ head in text but „Poetry“ will be shown in page header and TOC. Unfortunately, the trick from http://wiki.contextgarden.net/Titles#Flushing_ section_head_data_without_typesetting_them_in_the_text seems to not work for me. Thanks for help. -- Mikoláš Štrajt

Feature Request: define colour in relation to existing colour
by Thangalin 21 Aug '13

21 Aug '13

Hi, What would it take to extend \definecolor so that: \definecolor[ColourA][ColourB][t=0.5, a=1] defines a new colour (ColourB) based on an existing colour (ColourA)? I know that \definespotcolor[ColourA][ColourB][t=0.5, a=1] works, but it seems like \definecolor would also be a natural fit. Kind regards.

Feature Request: showframe debugging
by Thangalin 21 Aug '13

21 Aug '13

Hi, \showframe [ labels=on, measurements=on, color=red, ] Would produce an image similar to the attached, but with the black lines drawn in the specified colour. Using labels=on would show the names of the items that can be changed with \setuplayout. Using measurements=on would show the values for each of the items. I don't know if there is any value separating the measurements from the labels. Thank you!
