math symbol bug ?
by fares.benmena＠free.fr 08 Jan '11

08 Jan '11

Dear ConTeXt developpers, While trying to use mkiv, I noticed that the output of the "\div" macro in math mode is not the division symbol as I was expecting but the "div" text. I didn't find any mention about the changes that affect the math symbols, thus considered this behavior as a bug. I apologize if I'm wrong about it. Sincerely yours F. BEN MENA

Including xfig graphics
by Florian Unglaub 08 Jan '11

08 Jan '11

Hi there, I'm pretty new to ConTeXt and stumbled upon a problem when trying to use Xfig: I'm trying to create figures with xfig and including them in my ConTeXt document. I would export them as PDF, but unfortunately I have TeX math inside the figure and I'd like to have native fonts. I used to use a combinded LaTeX/PDF export in the past with LaTeX. Is there any practical solution to this? Regards, Florian.

What has happened to externalfigure command?
by Verhaag, G.C.H.M. 08 Jan '11

08 Jan '11

Hi, I'm struggling to get an older ConTeXt file that worked well under TeXLive 2008, but not any more with ConTeXt minimals! I've installed the ConTeXt minimals (Mark IV!) (MTXrun | current version: 2010.07.30 11:35) recently. I've a file someplot.1 in a directory called /home/somewhere. The ConTeXt source file contains the command: \setupexternalfigures [directory={/home/somewhere}] in the preamble. The image file is called using: \leftaligned{\externalfigure[someplot.1][scale=100]} But no image is presented in the generated pdf-file! However, all jpg-type of images that I use in the document - using similar commands - are all rendered correctly! What's wrong? Anybody any idea? Regards, Gerard Verhaag

\tfx or \tfxx is fail with nonintegral fonts size

Hi all, I find the "\tfx" or "\tfxx" is fail in nonintegral fonts size with latest beta (MKIV), but the "\small" was worked. example: \starttext \switchtobodyfont[15.01pt] \tfxx test \switchtobodyfont[15pt] \tfx test \switchtobodyfont[15.01pt] \small test \stoptext -- Best regards, Huang Ze

How to get numbered cases'ed equations ?
by Cedric Mauclair 07 Jan '11

07 Jan '11

Hi list, How can I get a numbered equation when using cases in MkIV? The "hack" proposed by Aditya in [1] doesn't work as it uses macros that no longer exist (\makesesctionnumber and others). The reference doesn't even get recorded. I precise that I don't want (well, don't need) the sub numbering per-line, just a regular number would do. Minimal example: \starttext My equation \in[eq:equation] and my other equation \in[eq:other-equation]. \placeformula[eq:equation] \startformula E = mc^2 \stopformula \placeformula[eq:equation] \startformula \startcases \NC E = mc^2 \NC some text\NR \NC E = mc^2 \NC some more text\NR \stopcases \stopformula \stoptext Thanks.

xml-processing: missing or ungrouped '='
by Achim Jander 07 Jan '11

07 Jan '11

Hi all a problem with processing XML data (maybe a lack of knowledge). If in the example below I set the chapter-attributes directly in \startxmlsetups xml:title (commented out) everything is like I expected. Because I have headings to be treated equally in multiple hierarchies I tried to delegate the processing to splitHeader. But then the processing always complains about a missing or ungrouped '=' in line ... (activated in the examle given). \startbuffer[test] <a> <title>some text</title> more text more text <title><num>333</num>some text</title> more text more text </a> \stopbuffer \startxmlsetups xml:testsetups \xmlsetsetup{\xmldocument}{a|b|title}{xml:*} \xmlsetsetup{\xmldocument}{num}{-} \stopxmlsetups \xmlregistersetup{xml:testsetups} \startxmlsetups xml:a \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:b \startparagraph \xmlflush{#1} \stopparagraph \stopxmlsetups \startxmlsetups xml:ueberForceFlush \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:splitHeader %works not number=\xmldoifelse{#1}{/num}{yes}{no}, ownnumber=\xmldoifelse{#1}{/num}{\xmlcommand{#1}{/num}{xml:ueberForceFlush}}{}, title={\xmlflush{#1}}, \stopxmlsetups \startxmlsetups xml:title \startchapter[ \xmlcommand{#1}{.}{xml:splitHeader} %number=\xmldoifelse{#1}{/num}{yes}{no}, %works %ownnumber=\xmldoifelse{#1}{/num}{\xmlcommand{#1}{/num}{xml:ueberForceFlush}}{},%works %title={\xmlflush{#1}},%works ] \xmlflush{#1} \stopchapter \stopxmlsetups \setupheader[chapter][ownnumber=yes] \starttext \xmlprocessbuffer{main}{test}{} \stoptext Thanks, Achim

still struggling with footnotes
by Achim Jander 07 Jan '11

07 Jan '11

Hi all, I am still trying to get the footnote numbers aligned in a special way: flushright, but the width depends on the width of the max footnote-number on page, so to get 1 2 and ~9 10 After reading the manuals and the source given in strc-not.lua thats how far i am at the moment: \enabletrackers[structures.notes] \setupnote[footnote][numbercommand=, way=bypage] \setupnotedefinition[footnote][location=left,distance=1em,hang=4,headalign={flushright},width=1em] \def\getmaxnote[#1]{\ctxlua{ local n = structures.notes.getn("#1",n) local current = structures.notes.get("#1",n) local cr = current.references local result = cr.realpage -- calculate the width of cr.number and store in maxwidth -- loop through the notes until act.realpage <> cr.realpage -- and for each note calculate the width, compare with maxwidh and store the max -- then set the width to the correct maxwidth -- context.setupnotedefinition({"footnote"}, {width=maxwidth}) } } \appendtoks \getmaxnote[footnote] \to\everybeforenoteinsert \showframe \starttext \dorecurse {100} { test \footnote{test } } \stoptext Now I can not figure out how to get the "real" footnote-number of the note (is there any way?) And does this approach make sense at all? Any hints welcome, i tear my hair for hours now Greetings, Achim

kerning info (mkiv)
by Peter Rolf 07 Jan '11

07 Jan '11

Hi, for a text background graphic I need the character box sizes of a given string. I managed to collect the needed info (width, height, depth, kerns), but there is still some flaw in the kerning part. For example: "VATo" is printed out (in the shell) as V 12 11 0 *kerning -85721.088 A 10 11 0 *kerning -64487.424 T 10 11 0 *kerning -64487.424 o 7 7 0 The character stands in the first column, followed by width, height and depth (in pixel). The "*kerning" line shows the kerning value (in sp) of the neighbouring character pair. No problem here. But "A much longer Test graphic VATo" A 12 11 0 5 0 0 m 13 7 0 *kerning -21233.664 u 8 7 0 c 7 7 0 *kerning -21233.664 h 8 11 0 5 0 0 l 4 11 0 o 7 7 0 n 9 7 0 g 8 7 3 e 7 7 0 r 6 7 0 5 0 0 T 11 11 0 e 7 7 0 s 6 7 0 t 6 10 0 5 0 0 g 8 7 3 r 6 7 0 a 8 7 0 p 9 7 3 h 8 11 0 i 4 10 0 c 7 7 0 5 0 0 V 12 11 0 A 12 11 0 T 11 11 0 o 7 7 0 sees no kerning for "VATo" (although the text is printed with the correct kerning). What am I missing? Example code is attached. Peter

Fontfeature: smcp
by Willi Egger 07 Jan '11

07 Jan '11

Hm, has something change in the way a font feature should be implemented? This used to work: \definefontfeature[smallcaps][default][script=latn,smcp=yes] \starttypescript [sans] [seravek] [name] \definefontsynonym [Seravek-Roman] [file:Seravek-Regular] [features=default] \stoptypescript \starttypescript [sans] [seravek] \definefontsynonym [Sans] [Seravek-Roman] [features=default] \definefontsynonym [SansRegularCaps] [Sans] [ features=smallcaps] \stoptypescript \starttypescript [Seravek] \definetypeface [Seravek] [ss] [sans][seravek][default] \definetypeface [Seravek] [mm] [math][palatino][default] \stoptypescript \usetypescript[Seravek] \setupbodyfont[Seravek,ss,12pt] \starttext This is \fontname\font. {\sc This is \fontname\font.} \stoptext I get no smallcaps. If I add \def\sc{\addff{smcp} I get still no smallcaps. Willi
