bizarre error message
by Thomas A. Schmitz 01 Apr '14

01 Apr '14

Hi, I haven't yet been able to reproduce this in a minimal example, but I'm trying to place some images within a mixedcolumns environment, and I get an error message I have never seen before: pages > flushing realpage 5, userpage 5 Node 1150 has an attribute list that is free already Node 1406 has an attribute list that is free already Node 1373 has an attribute list that is free already Node 1228 has an attribute list that is free already Node 1195 has an attribute list that is free already Node 1114 has an attribute list that is free already Node 1127 has an attribute list that is free already Node 1074 has an attribute list that is free already Node 2011 has an attribute list that is free already Node 2268 has an attribute list that is free already Node 2116 has an attribute list that is free already Node 2030 has an attribute list that is free already Node 1981 has an attribute list that is free already Node 1953 has an attribute list that is free already Node 3055 has an attribute list that is free already Node 2889 has an attribute list that is free already luatex: ../../../source/texk/web2c/luatexdir/tex/texnodes.w:1985: delete_attribute_ref: Assertion `varmem[(b)].hh.u.B0==attribute_list_node' failed. mtx-context | fatal error: no return code, message: luatex: execution interrupted% This is with context 2014.03.28 15:04 and luatex 0.78.2 on linux 64-bit. The error does not appear with a beta version from january 2014. Any idea where this might come from? Thomas

Problems with XML and table of contents
by Xan 01 Apr '14

01 Apr '14

Hi, I have this: \definehead [Fitxa] [subsubject] \setuphead [Fitxa][textstyle=sca,align=normal,color=headingcolor,before={},ownnumber=yes,incrementnumber=yes,number=no,strut=no] \setuplabeltext [Fitxa=Fitxa] \setuplist[Fitxa] [margin=4em,interaction=text,color=green,textcommand=\WORD] %\setuplist [Fitxa] [width=2em,criterium=all,interaction=all] \newcounter\FitxaNumber \def\fitxa#1% {\doglobal\increment\FitxaNumber \Fitxa{\FitxaNumber}{#1}} \setupcombinedlist[content][list={chapter,section,subsection,Fitxa,tasca},interaction=all,textcolor=black] and \startxmlsetups xml:demo:titol \fitxa{\xmltext{#1}{/}} \stopxmlsetups In the document all is ok, but in the table of contents, I get "phantom" content. Any clue? Thanks in advance, Xan

Aditya filter module: ignore ``` in my case

Hi, I have a problem: why this \usemodule[filter] \defineexternalfilter [markdown] [filtercommand={pandoc -f markdown+multiline_tables+table_captions -t context -o \externalfilteroutputfile\space \externalfilterinputfile}] \starttext \startmarkdown Decideix l'esquema de particions que *tendré* ``` | Partició | Espai | Muntatge | | sda1 | | /var/log % | PROVA %=Regime \enableregime[utf] %=Choose a language, and associated hyphenation rules. \mainlanguage[ca] %= Colors \setupcolors[state=start] \definecolor[headingcolor][c=1,m=0.5431,y=0,k=0.5451] \definecolor[steelblue][h=4682B4] \definecolor[griscodi][h=F5F5F5] ``` \stopmarkdown \stoptext does not process the code block (inside ```)? I just wonder why? Thanks, Xan.

TLS and externalfigure
by Thangalin 30 Mar '14

30 Mar '14

Hi, I have images hosted on a local web server using a self-signed certificate. For example: https://localhost/images/.../file.png When using ConTeXt, the image cannot be retrieved; a verified signed certificate works as expected. Using wget, self-signed certificates can be forced: wget --no-check-certificate https://localhost/images/.../file.png Does ConTeXt have a way to ignore/bypass certificate validation? If so, how? (Note: the certificate's common name is currently blank, which does not match 'localhost' -- I can fix that if required...) Thank you!

Feature request: use rsvg-convert
by Thangalin 30 Mar '14

30 Mar '14

Hi, Re: http://wiki.contextgarden.net/Using_Graphics#Image_Conversion I recommend using rsvg-convert instead of inkscape. For example: wget http://en.wikipedia.org/wiki/File:Inkscape_0.48.2_with_Red_Gallardo.svg -O car.svg time rsvg-convert --format pdf car.svg --output car-rsvg.pdf time inkscape --file=car.svg --export-pdf=car-inkscape.pdf --without-gui wget http://openclipart.org/download/people/TheStructorr/TheStructorr_Lamborghin… -O car2.svg time rsvg-convert --format pdf car2.svg --output car2-rsvg.pdf time inkscape --file=car2.svg --export-pdf=car2-inkscape.pdf --without-gui Here, inkscape is slightly faster yet produces slightly larger files. inkscape 0.48.4 r9939 (Jan 22 2014) rsvg-convert version 2.40.2 More importantly, inkscape renders incorrectly. The horizontal and vertical rule marks are missing in the first image. The gradient shadows are missing in the second image, and the grill is incorrect (looks like a layer order issue).

mirrored leftmarginwidth in enumerations
by Sanjoy Mahajan 30 Mar '14

30 Mar '14

If anyone has a suggestion for putting enumeration texts toward the right edge of the left margin, I would be grateful. In MkII enumerations, I would put a triangle (fig.2) in the left margin using \defineenumeration [pause] [title=no, text={\externalfigure[fig.2][height=1em]}, location=inleft, number=no, ] The triangle was automatically aligned toward the right side of the left margin (fill glue on the left), which was what I wanted, on even and odd pages. In MkIV, the marginal text is automatically aligned to the left side. I restored the MkII effect using this hack (using a > instead of the triangle, to make the example more self contained): \defineenumeration [pause] [title=no, text={\hbox to \leftmarginwidth{\hfil $>$}}, number=no, alternative=inleft, ] But I just realized that the hack doesn't work for double-sided layouts. Using the leftmarginwidth is correct on the odd pages, but it is too big for the even pages. Thus, on page 2 of the example below, the > overlaps the "question" text. Is there a more idiomatic MkIV replacement for my hack? Or is my hack okay, but ConTeXt should be updated to interpret leftmarginwidth to mean "the leftmarginwidth, as appropriate for an odd or an even page"? Here is the example: \setuplayout[marking=on,location=middle, backspace=1.25in, leftmargindistance=0.125in, leftmargin=0.625in, width=4.75in, rightmargindistance=0.25in, rightmargin=0.25in, ] \setuppagenumbering[alternative={doublesided}] \defineenumeration [pause] [title=no, text={\hbox to \leftmarginwidth{\hfil $>$}}, number=no, alternative=inleft, ] \def\question#1{\startpause\relax #1 \stoppause} \showframe \starttext \question{hello} \page \question{hello} \stoptext

PDF document metadata: keyword and date
by Pablo Rodriguez 30 Mar '14

30 Mar '14

Dear list, I have the following sample: \setupinteraction[state=start, author={I, Me}, keyword={interactive document, ConTeXt}, date=03-02-2004] \starttext Hi.\page Hi. \stoptext I have two questions: How can I avoid the removal of commas in the keyword option? How should I specify the date option? (Even with the format D:199812231952-08'00, I don’t get it working.) Many thanks for your help, Pablo -- http://www.ousia.tk

Defining commands in \start ... \stop
by Xan 30 Mar '14

30 Mar '14

Hi, Concerned with the answers to the [that topic](http://www.ntg.nl/pipermail/ntg-context/2014/077099.html), I was thinking if I could define a command "Exercise" with a optional argument (the "Answer"). \defineblock[question] \defineblock[answer] \defineenumeration[question][text={Question}] \defineenumeration[answer] [text={Answer}] \keepblocks[question] \hideblocks[answer] Something like \startexercise My execise ... \stopexercise If no more is provide, at the question does \incrementcounter[answer] If \startexercise{\startsolution The solution is \stopsolution} My exercise \stopexercise then \beginanswer and \startanswer is called. Is it possible? I just want to know if it's better to have \startBla...\stopBla command or \Bla{} command type? In the case of the first, how do you define that? I did not find it here (http://wiki.contextgarden.net/Commands_with_optional_arguments) Thanks, Xan PS: Please CCme

PDF bookmarks issue with heads
by Pablo Rodriguez 29 Mar '14

29 Mar '14

Hans, just accidentally, I discovered that adding a head (the content list itself) before the front matter disorders PDF bookmarks (bodymatter is before frontmatter). Here is a sample \setupinteraction[state=start] \placebookmarks[chapter,section] \starttext \completecontent %~ \title{Contents} %~ \chapter{Contents} \startfrontmatter \dorecurse{3}{\chapter{Chapter in frontmatter} \section{Section in frontmatter}} \stopfrontmatter \startbodymatter \dorecurse{3}{\chapter{Chapter in bodymatter} \section{Section in bodymatter}} \stopbodymatter \stoptext Many thanks for your help, Pablo -- http://www.ousia.tk
