dead link in wiki
by Damien Thiriet 24 Jul '17

24 Jul '17

Hi, There may be an error in contextgarden's link to NTG MAPS "search the articles" link. It points to http://www.ntg.nl/maps/search.html which seems to be a dead link. I could reach the english version typing http://www.ntg.nl/maps/mapssearch-en.html The proper link for dutch version is http://www.ntg.nl/maps/mapssearch-nl.html. Best regards, Damien Thiriet

Compare contents of macros via \doif etc. alternatives

Hello ConTeXist. Is there any way to evaluate of contents of two macros as I am showing in my minimal example? I know, that problem is in expansion, but I dont know to resolve it. My minimal example consist of piece lua code, because I am solving my problem in mixed codes (TeX & Lua) Thanx for help.

footnote placement
by Meer, Hans van der 21 Jul '17

21 Jul '17

It happens that a footnote generated on a certain page is typeset on the page preceding it. Rather than that, I would like to force a footnote to appear either on the page where it is defined or on the following page. Can such behaviour be enforced? Currently this is my footnote setup: \setupnotes [footnote][split=verystrict] \setupnotation[footnote][way=bypage,numberconversion=set 2,headstyle=small] Hans van der Meer

replace characters with bounding boxes
by Idris Samawi Hamid ادريس سماوي ح امد 20 Jul '17

20 Jul '17

Dear gang, Given a set body font and text, how does one replace all characters of that font in that text with the corresponding rectangular bounding boxes? Once an answer to the above is spelled out: How does one control the width of the lines which make up the bounding boxes? Thank you in advance. Best wishes Idris -- Idris Samawi Hamid, Professor Department of Philosophy Colorado State University Fort Collins, CO 80512

t-vim module: math in "normal" code and background color
by Gerion Entrup 19 Jul '17

19 Jul '17

Hi, I have two questions with the vim module. 1. I want to use the math mode inside the code. I've seen the escape option, e.g. here [1], but this seems to work only with comments. Is there a possibility to use it directly in the code, too? Minimal example: ``` \usemodule[vim] \definevimtyping[python][syntax=python, escape=on] \starttext \startpython # Returns \m{\sum_{i=1}^{n}i} def sum_upto(\m{n \in \mathbb{N}}) r = range(1, \m{n} + 1) return sum(r) \stoppython \stoptext ``` 2. It would be cool, if I can define some background color for the code. Unfortunately I'm very new to context and haven't seen a direct option. I assume this is possible with some kind of extra environment around the code? (I've subscribed the list, so you don't have to CC me.) Thank you in advance, Gerion

synctex
by Hans Hagen 19 Jul '17

19 Jul '17

Hi, For those using synctex, an alternative method is: \setupsynctex[state=start] It is tuned for use in a more complex setup where one wants access to source files (with content) and not to e.g. styles in a tex tree. It also works reasonable well with (also included) xml files. Personally I never use synctex but for some projects it came in handy for authors (think of proofing xml files with hundreds of nested inclusions and files in a rather branched tree.) Of course you can expect a similar performance hit as normal synctex but commenting the above line in production results in zero overhead. Using the syntex flag on the command line (--synctex=context will work) can be messy. This currently only works with the windows binaries version on the garden (as we need luatex 1.0.5).

\xmlfirst broken?
by Henri Menke 17 Jul '17

17 Jul '17

Dear list, A recent question on TeX.SX is asking about XML processing. https://tex.stackexchange.com/questions/380935 To reproduce the error from the question I copied the demo from the XML manual. First of all we have demo.xml: <?xml version='1.0' standalone='yes'?> <document> <section> <title>Some title</title> <content> <p>a paragraph of text</p> <p>another paragraph of text</p> </content> </section> </document> And then we have a ConTeXt document: \startxmlsetups xml:demo:base \xmlsetsetup{#1}{*}{-} \xmlsetsetup{#1}{document|section|p}{xml:demo:*} \stopxmlsetups \xmlregisterdocumentsetup{demo}{xml:demo:base} \startxmlsetups xml:demo:document \starttitle[title={Contents}] \placelist[chapter] \stoptitle \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:demo:section \startchapter[title=\xmlfirst{#1}{/title}] \xmlfirst{#1}{/content} \stopchapter \stopxmlsetups \startxmlsetups xml:demo:p \xmlflush{#1}\endgraf \stopxmlsetups \starttext \xmlprocessfile{demo}{demo.xml}{} \stoptext This works partially. Some entities are printed fine but stuff in \xmlfirst is missing. I can reproduce this in TL2017 and latest beta. In the attached PDF you can see that the section has no title and no content (exactly the stuff \xmlfirst was supposed to get). Cheers, Henri

Error with Libertinus Semibold and new standalone beta

With the example below and the latest beta (2017.07.14 19:35), I get the following error whenever a bold face is requested: lua error > lua error on line 44 in file C:/Users/rik/Desktop/test/prod_quotation.tex: ...ext/tex/texmf-context/tex/context/base/mkiv/font-ots.lua:5336: attempt to index local 'one' (a boolean value) The typescript in the example is based on the delivered typescript with the replacement of bold fonts by semibold.
