Iterate through a directory
by Keith McKay 04 Jul '16

04 Jul '16

Colleagues I'm preparing a booklet of figures which are stored in a directory, however their is no structure in their naming. I could go through them all and rename them along the lines of Pict1.jpg, Pict2.jpg etc and \dostepwiserecurse as in the example below \setupexternalfigures [directory={/a/directory}] \starttext \dostepwiserecurse{1}{10}{1} { \externalfigure[Pict\recurselevel.jpg] } \stoptext However, I was wondering if was possible to iterate through the directory using a wildcard and have something like \externalfigure[*.jpg} to make it generic, or would I have to use lua. Best Wishes Keith

disabling page scaling
by Pablo Rodriguez 04 Jul '16

04 Jul '16

Dear list, I have the following sample: \setupinteractionscreen[option={paper,page}] \starttext \ConTeXt\ is awesome! \stoptext The values for the option key should enable "/PickTrayByPDFSize true" and "/Duplex /Simplex" in the PDF file. But I get an undesired "/PrintScaling /None" (I need to reduce the document to printing margins.) Checking lpdf-mis.lua, I see that there are two lists (or dictionaries, maybe [the technical term is beyond my knowledge]) controlling the printing options: pagespecs and plusspecs (both are local). page, portrait, landscape and paper involve fixed in the pagespecs dictionary. But these values don’t involve fixed in the plusspecs dictonary. How can I invoke the plusspecs dictionary from ConTeXt, so I can get duplex printing in the PDF file (or "/PickTrayByPDFSize true") without having to disable page scaling? Many thanks for your help, Pablo -- http://www.ousia.tk

prerrolling PDF fields
by Pablo Rodriguez 04 Jul '16

04 Jul '16

Dear list, I have the following sample: \def\BookTitle{{\itd A \ConTeXt\ Book}} \def\BookAuthor{{\sc The Author}} \setupinteraction[state=start, title=\BookTitle, author=\BookAuthor] \enabledirectives[references.bookmarks.preroll] \placebookmarks[chapter,section,subsection] \starttext \chapter{\BookTitle} \section{\BookAuthor} \subsection{\ConTeXt\ is \TeX, but not \LaTeX} \stoptext Is there a way that I can preroll or expand the commands so that PDF info fields have the same text as the bookmarks? And another request, could \TeX (and others) be prerolled to TeX instead of TEX? I think that there are two reasons in favor of this change: 1. From scrn-ini.mkvi: creator {ConTeXt - \contextversion}% 2. The TeXbook includes \TeX, no \TEX. Many thanks for your help, Pablo -- http://www.ousia.tk

\pushbackground for header/footer
by Mohammad Hossein Bateni 04 Jul '16

04 Jul '16

Hi, Can one use {push,pop}background to save/restore backgrounds for header*text and/or footer*text areas? I'm trying to typeset a document where one page has a special background, which I set using \setupbackgrounds[header][text][background=color,backgroundcolor=gray]. Can I go back to the default setting afterwards or do I need to specify it explicitly. I know I can save whatever I put in \setupbackgrounds[page] using \pushbackground[page] and \popbackground. I could not get it to work with header/footer. \setupcolors[state=start] \showframe \setupbackgrounds[header][text][background=color,backgroundcolor=yellow] \starttext One \page %\pushbackground[page] \pushbackground[header][text] \setupbackgrounds[header][text][background=color,backgroundcolor=gray] Two \page \popbackground Three \stoptext Thanks, MHB

hz in MkIV
by Mohammad Hossein Bateni 04 Jul '16

04 Jul '16

Hi, In MkIV, the syntax for using hz seems to have changed from \setupfonthandling to \setupfontexpansion (similarly for protrusion). What is the equivalent of the following? Is this feature supported in MkIV and LuaTeX? I tried changing/adding entries to fonts.expansions.vectors.quality (and .default) to no apparent avail. \startfonthandling [hz] \defineadjustfactor A .5 \defineadjustfactor B .7 \defineadjustfactor C .7 ... \stopfonthandling In any case, I'm happy that hz works for Arabic/Farsi despite some warnings suggesting the contrary ( https://mailman.ntg.nl/pipermail/ntg-context/2008/029765.html) It does make certain Farsi texts look better, however, support for tatweel/kashida would be ideal. In fact, I was trying to see if I could somehow get it to work, building on top of hz. Hans, do you have any suggestions for this? Would this be feasible and/or worth trying? I once converted Vafa Khalighi's XeTeX-based code to Lua but ran into several setbacks. (The idea is to insert a sequence of (ZWJ,\nobreak,stretchable leader,\nobreak,ZWJ) between certain character pairs that join one another.) Here are some of the issues I faced: 1) This could not be turned off and on within a paragraph because I was hooking into processors.before action. 2) The mechanism for some (all?) center alignments (including default figure captions) interferes with what I was hacking (or, to be more precise, it's the other way around) and causes unnecessary use of tatweel in those settings. 3) Later I noticed that the added sequence did not inherit many properties (like font style or color). 4) The optimum values for the stretches I put in depend on the context, particularly because some environments manipulate \spaceskip for other reasons. Sorry for the mumbling. I can explain more if anyone is interested in helping to improve this functionality. Attached is what I have now. Thanks, MHB

RTL bug in textbackground
by Mohammad Hossein Bateni 03 Jul '16

03 Jul '16

Hello, When using \definetextbackground in RTL setting, the boundaries are not determined correctly (both for location=paragraph and location=text) and colors gets messed up. Here a sort-of-minimal example adapted from details.pdf. Is there any particular keys I should use in RTL to fix the issue? \setupcolors[state=start] \definecolor[infogray][s=0.5] \definecolor[textgray][s=0.8] \definetextbackground[intro] [backgroundcolor=infogray, backgroundoffset=.25cm, offset=.5cm, frame=on,framecolor=red, location=paragraph, color=white] \definetextbackground[subintro] [backgroundcolor=textgray, backgroundoffset=0pt, offset=0pt, frame=off, location=text, color=blue] \starttext \starttextbackground[intro] A rather common way to draw attention to a passage, is to add a background. In this chapter we will therefore discuss how to enhance your document with \starttextbackground [subintro] colorful areas that either or not follow the shape of your paragraph. \stoptextbackground\ Be warned: this chapter has so many backgrounds that you should consider wearing sunglasses. \stoptextbackground \blank[3*big] \righttoleft \starttextbackground[intro] A rather common way to draw attention to a passage, is to add a background. In this chapter we will therefore discuss how to enhance your document with \starttextbackground [subintro] colorful areas that either or not follow the shape of your paragraph. \stoptextbackground\ Be warned: this chapter has so many backgrounds that you should consider wearing sunglasses. \stoptextbackground \stoptext Thanks, MHB

Equivalent of extras option in new bibliography system?

In the past (MKII) I used citations of the form: \cite[extras={, p.~24}][Author:2016] The extras option seems to be ignored by MKIV's bibliography system. What is the equivalent of the above? Nicola

trying to delete an attribute reference of a non attribute node
by Marco Patzer 03 Jul '16

03 Jul '16

Hi! The following example throws the error: ! error: (nodes): trying to delete an attribute reference of a non attribute node mtx-context | fatal error: return code: 1 \setbreakpoints [compound] \useMPlibrary [dum] \starttext \startTABLE \NC \externalfigure [foo-bar] [width=\textwidth] \NC foo bar foo bar foobarfoobar \bold{aaaaaaaaaaaa} \NC\NR \stopTABLE \stoptext Sorry for the not so minimal example. In the actual text I'm not using the `dum` library, I'm including actual graphics. So I don't believe that's the issue. It might have something to do with word breaking, that's my gut feeling. What is the issue here? ConTeXt ver: 2016.06.26 19:00 Marco
