sudden error
by jbf 22 Aug '20

22 Aug '20

Am suddenly getting the error: close source > level 1, order 3, name '/home/me/Documents/Freedom/Context/tex/texmf-context/tex/context/base/mkiv/cont-yes.mkiv' ! error: (type 0): cannot find file ''mtx-context | fatal error: return code: 256 I really don't think I have done anything to remove any essential parts of ConTeXt. Of course I can reinstall, but before I do, it would be good to understand what could have caused this error or if, indeed, it might be easily fixed even without reinstalling (a standalone). Julian

removing word in filtered XML
by Pablo Rodriguez 21 Aug '20

Dear list, I have the following sample: \startbuffer[demo] <html> <body> <div id="First"> This is One of the best a paragraph. This is another paragraph. This is another Two of the best paragraph. This is another Three paragraph. This is another Four of five paragraph. </div> </body> </html> \stopbuffer \startxmlsetups xml:initialize \xmlsetsetup{#1}{html}{xml:gen} \stopxmlsetups \xmlregistersetup{xml:initialize} \startxmlsetups xml:gen \xmlfilter{#1}{/**/div/command(xml:special)} \stopxmlsetups \startxmlsetups xml:special %~ \startitem \cldcontext{string.gsub(lxml.flush([[#1]]), " of the ", "")}\stopitem \stopxmlsetups \starttext \xmlprocessbuffer{main}{demo}{} \stoptext Is there any way to remove " of " and " of the " in the filtered content (xml:special)? Sorry, Lua code is crap for sure. Many thanks for your help, Pablo -- http://www.ousia.tk

Chapter heading with rules
by jbf 21 Aug '20

21 Aug '20

Have achieved a Chapter title with rules either side (see below - not an original invention!) but I want the chapter number to be part of 'My Chapter Title'; instead, the following MWE means it comes before the ChapterLeftRule. I know I can do it by actually putting the number before My Chapter title (e.g. 1 My Chapter Title), since the proper numbered version still appears in the TOC, but my preference would be to include a command in the \setuphead, if possible (so long as it still allows the numbered chapter to appear in the TOC of course). Possible? \definefiller [ChapterRule] [alternative=rule, color=gray, height=0.8ex, depth=-0.6ex] \definefiller [ChapterLeftRule] [ChapterRule] [left=\zerowidthnobreakspace, right=\quad] \definefiller [ChapterRightRule] [ChapterRule] [left=\quad, right=\zerowidthnobreakspace] \setuphead [chapter] [%align=middle, textstyle={\setcharactercasing[WORD]\ssa}, textcommand=\groupedcommand{\filler[ChapterLeftRule]}{\filler[ChapterRightRule]}] \starttext \chapter{My Chapter Title} \stoptext Julian

Chapter numbering after \part
by jbf 20 Aug '20

20 Aug '20

By default, chapter numbers coming after \part are numbered 1.1... 2.1... and so on. But in my case I need them to still be simply 1,2... for each part. Is there a way I can get this numbering to occur? I thought I could do it using ownnumber=, but that doesn't work. Then I tried a makeup, because I thought that would create a 'Part' page independent of chapter numbers - but that doesn't work either:-). Am sure it is achievable, however.... Julian

custom header/footer for 1st/other pages of section
by Mike Cooper 20 Aug '20

20 Aug '20

Hola, I imagine this is probably simple but I can't find it... I want the first page only of each section to have particular content in header/footer, then all the following pages to different specific content. Right now, I am manually entering it in each section. I'm hoping there's a way to automate this; put it into the environment file for all sections. THANKS FOR YOUR HELP!

[BUG] \registerexternalfigure doesn't work
by Henri Menke 20 Aug '20

20 Aug '20

Dear list, To get properties of a figure without actually typesetting it, it is handy to use \registerexternalfigure. However, trying to use it fails. Consider the following MWE: \starttext \registerexternalfigure[cow.pdf] \stoptext Looking at the definition in grph-inc.mkiv reveals that is it complete bogus. \unexpanded\def\registerexternalfigure {\dotripleempty\grph_include_register} \def\grph_include_register[#1][#2][#3]% {\startnointerference \c_grph_include_test_only \setfalse\c_grph_include_flush % == test ? \externalfigure[#1][#2][#3]% or \externalfigure[#1][#2,\c!display=,\c!mask=,\c!object=\v!no]% \stopnointerference} I guess this is not intentional and was left over at some point. Could you please fix this? Cheers, Henri

TOC chapter and section numbering
by Adrian 19 Aug '20

19 Aug '20

Hello, I'm attempting to typeset a short book using ConTeXt (current version: 2020.08.09 22:03). EXAMPLE: \setuplist[content][alternative=c] \setuphead[title][alternative=middle,style=cap] \setuphead[chapter][number=no] \setuphead[section][sectionsegments=section] \setuplist[section][width=1.5em,margin=3em] \starttext \title{contents} \placecontent \startchapter[title={Introductory}] \startsection[title={The concept of a function}] \stopsection \startsection[title={Extension and intension}] \stopsection \startsection[title={Functions of several variables}] \stopsection \startsection[title={Abstraction}] \stopsection \stopchapter \startchapter[title={Lambda-Conversion}] \startsection[title={Primitive symbols, and formulas}] \stopsection \startsection[title={Conversion}] \stopsection \startsection[title={Fundamental theorems on well-formed formulas and on the normal form}] \stopsection \stopchapter \stoptext I would like all the chapters to be prefixed with "Chapter RN." and the sections to keep a single count, for example: Chapter I. Introductory ..... 1. The concept of a function 2. Extension and intension 3. Functions of several variables 4. Abstraction Chapter II. Lambda Conversion ..... 5. Primitive symbols and formulas 6. Conversion 7. Fundamental theorems on well-formed formulas and on the normal form I tried to the following for the chapters: \defineconversion[church][Chapter \Romannumerals.\quad] \setuphead[chapter][conversion=church] Which appeared to generate the prefix correctly but it overlapped the title. Any help would be greatly appreciated. Thanks Adrian

Re: [NTG-context] memoir-style chapter heading
by jbf 18 Aug '20

Thank you Otared. The power of ConTeXt never ceases to amaze me, though despite the excellent work done on the wiki recently, it is the little things like the use of \raise that could be better described, especially in a range of applied instances. We find it, combined with hbox, in reference to marginal and centered headers, but it is not intuitive - for me at least - to be able to apply it as you have done in your example. The little process we have gone through, which is step-by-step, is most helpful, and I feel that I can now use these ideas in other instances and in slightly different ways. Thank you. How important is the 'lohi' addition you made to \framed? I removed it to see what would happen and did not notice any appreciable difference in the output.

Chapter number with Luametafun
