contextual alternates
by Pablo Rodriguez 25 Jan '15

25 Jan '15

Dear list, I have the following sample: \definefontfeature[default][default][script=latn, calt=yes] \definefontfamily[mainface][serif][Pecita] \setupbodyfont[mainface] \starttext \input zapf \stoptext The Pecita font is licensed under the Open Font License and it can be downloaded at http://pecita.eu/b/Pecita.otf. For some strange reason, the contextual alternates feature isn’t working. What am I missing here? Many thanks for your help, Pablo -- http://www.ousia.tk

In regular Context font usage I have this statement that works: \def\Fontsize{13} \font \rm = "file:MinionPro-Regular.otf:+liga;expansion=default;protrusion=quality" at \Fontsize bp How would I use this font in simplefonts? it is the trailing parameters that I don't know how to use in simplefonts, like: :+liga;expansion=default;protrusion=quality -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html Updated PDF e-book: "Create Book Covers with Scribus 1.4.5" coming soon at http://www.booklocker.com/!

by John Culleton 22 Jan '15

DTP programs like Inkscape and Scribus have facilities for linking to urls. Pdftex does also. If this facility exists in Context can some kind soul point me to the documentation?

bug when dealing with XML classes?
by Pablo Rodriguez 22 Jan '15

22 Jan '15

Hans, I have the following sample: \setupbodyfont[30pt] \startbuffer[demo] <doc> <h1>This is my title</h1> <div class="section" class="level1" class="hidden"> <h1>This title is hidden</h1> </div> <div class="section level1 hidden"> <h1>This title is not hidden</h1> <p>Text</p> </div> </doc> \stopbuffer \starttext \startxmlsetups xml:initialize \xmlsetsetup{#1}{div}{xml:div} \xmlsetsetup{#1}{h1}{xml:h1} \xmlsetsetup{\xmldocument}{[@id='epigraph']}{xml:epigraph} \xmlsetsetup{#1}{[@class='hidden']/h1}{} \stopxmlsetups \xmlregistersetup{xml:initialize} \startxmlsetups xml:div \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:h1 \section{\xmlflush{#1}} \stopxmlsetups \xmlprocessbuffer{main}{demo}{} \stoptext ConTeXt MkIV is not able to understand class="section level1 hidden" as class="section" class="level1" class="hidden" and the second attribution is invalid XML (according to the W3C Validator [http://validator.w3.org/] and xmlvalidation.com) class should be only specified once. I think this might be a bug in ConTeXt. Many thanks for your help, Pablo -- http://www.ousia.tk

counting characters when dealing with XML
by Pablo Rodriguez 22 Jan '15

22 Jan '15

Dear list, I have a question when dealing with XML. Is there any way to write a conditional based on the number of characters in a given field? I mean, the following field: \xmltext{#1}{h1[@class='subtitle']} If subtitle > 60 chars, then fontsize = 10pt. If subtitle > 50 chars, then fontsize = 12pt. If subtitle > 40 chars, then fontsize = 14pt. If subtitle > 30 chars, then fontsize = 16pt. How could I write these conditionals? Many thanks for your help, Pablo -- http://www.ousia.tk

Page Breaks after Headings
by Malte Stien 22 Jan '15

Hi all, Is there a way I can avoid page breaks after “headings”, i.e. \section, \subsection, \subject, \subsubject, etc? Thank you, Malte. -- “The Electric Monk was a labour-saving device, like a dishwasher or a video recorder...

Positioning an arrow between two values (Metapost)
by Fabrice Couvreur 21 Jan '15

21 Jan '15

Hi, I went from PSTricks to Metapost (Metafun) gradually. For positioning arrows between two values in an array of variations, I used a command like this \ ncline {A}{B}, which avoids fumbling. Can we do the same with Metapost ? The idea would be to convert the value into a path or an image, much like in the code below. \starttext \startMPcode u:=1cm ; path p, q ; p=fullsquare scaled u ; q=fullsquare scaled u shifted (4u,-2u) ; draw p ; draw q ; drawarrow center p--center q ; label(btex $5$ etex,center p) ; label(btex $-2 $ etex,center q) ; \stopMPcode \stoptext Best regards, Fabrice
