Marginrule levels after \placefigure[right]
by Aditya Mahajan 28 Aug '16

28 Aug '16

Hi, This is based on a question on TeX.SE https://tex.stackexchange.com/questions/326653/context-wrapfigure-interacts… All marginrules except those of level 1 stop working after \placefigure[right]. Here is a minimal example: \useexternalfigure[ctanlion][http://www.ctan.org/lion/ctan_lion_350x350.png][width=4cm] \starttext \placefigure[here,none,right]{}{\externalfigure[ctanlion]} \input knuth \startmarginrule[2] \input ward \stopmarginrule \startmarginrule[1] \input ward \stopmarginrule \startmarginrule[3] \input ward \stopmarginrule \stoptext The output is attached.

mathalignment and grid
by Henri Menke 28 Aug '16

28 Aug '16

Dear list, when I typeset multi line equations using mathalignment and grid the descenders of the last line of equation run into the first line of text after that equation. The problem is particularly bad with the Lucida fonts (I think the large operators are relatively larger than for Latin Modern). I could just increase the spacing after equation (commented out in the MWE below), but that would introduce an imbalance between space before and space after for all equations without descenders. Furthermore the problem does not arise for single line equations with descenders. Without grid there is also no problem. How do I fix mathalignment to prevent this? Cheers, Henri --- \setuplayout[grid=yes] \setupbodyfont[lucidaot,9pt] %\setupformulas[spaceafter={back,nowhite,2*line}] \showgrid \starttext \input ward \startformula \startmathalignment \NC \sum_{i,\alpha,\beta} c_{i,\alpha}^\dagger c_{i,\beta} \NR \NC \sum_{i,\alpha,\beta} c_{i,\alpha}^\dagger c_{i,\beta} \NR \stopmathalignment \stopformula %\blank[2*line] \input ward \startformula \sum_{i,\alpha,\beta} c_{i,\alpha}^\dagger c_{i,\beta} \stopformula \input ward \startformula \text{no descenders} \stopformula \input ward \stoptext

\restorecounter ignores first save
by Wolfgang Schuster 28 Aug '16

28 Aug '16

Hi Hans, the save/restore state for the counter in the example is ignored. %%%% begin example \enabletrackers[structures.counters] \definecounter[test] \starttext \incrementcounter[test] \convertedcounter[test] \dorecurse{10} {\savecounter[test] \incrementcounter[test] \convertedcounter[test] \restorecounter[test] \par} \stoptext %%%% end example The problem is the check for the table size in the counters.restore function because after the first save the size of the table is 1: function counters.restore(name) local cd = counterdata[name] if not cd then report_counters("invalid restore, no counter %a",name) return end local saved = cd.saved if not saved then -- is ok elseif #saved > 1 then cd.data = remove(saved) else report_counters("restore without save for counter %a",name) end end Wolfgang

\startalign \stopalign equation number placement seems wrong
by Mikael P. Sundqvist 28 Aug '16

28 Aug '16

Hi, The test file \starttext \placeformula \startformula \startalign \NC \exp(t_1)\exp(t_2)\NC =x_1x_2=\exp(\ln(x_1x_2))\NR \NC \NC =\exp(\ln x_1+\ln x_2)=\exp(t_1+t_2).\NR[eq:explag1] \stopalign \stopformula \placeformula \startformula 1+1=2 \stopformula \stoptext gives the attached pdf. In the first formula, the location of the equation number seems to be wrong (I would have expected it to be to the right, like in the second example). In the (nice, but rather old now) My Way by Aditya, this does not seem to happen. /Mikael

Problems with indexing (+feature requests)
by Mohammad Hossein Bateni 27 Aug '16

27 Aug '16

Hello, For a few days I have been playing with registers to generate an RTL index. Beside sorting, I ran into the following. 1) How can I get the index section using \subject? In some styles, I do not want to see the section number. 2) How can I get the Persian comma used instead of the English comma in page numbers and also before "see also"? The first one I can fix by a hack but not the second one: defining a custom pagecommand that sets \registerpageseparatorsymbol to the Persian comma! There is a TODO comment in strc-reg.mkiv that the comma customization has been planned. 3) In RTL registers, if an entry starts with an LTR char, the order of index entry and page number will be incorrect. We had similar issues with section headings before. I can "fix" this by setting pagestyle=\zwnj, but is there a more principled way to handle this? See the MWE below. 4) Is there a way to define the style of "see also" different from pagestyle? What if I want to distinguish "see also" from the actual entry this is referring to? 5) Currently I use \setupmixedcolumns[register][direction=reverse] to get the two-column register in the correct order. What if I have two index registers, one for RTL and another for LTR? Is there a way to set the direction key for a specific register? 6) In a two-column Persian index, using almost any (non-mono) font, some letter headings (those extending significantly below the baseline) end up with extra space below. See attached PDF and the MWE. (I could not reproduce this with DejaVuSans or ALM Fixed.) \definefontfamily [myfamily] [serif] [Scheherazade] [features=arabic] \setupbodyfont [myfamily] \setupalign[r2l] \setupdirections[bidi=global,method=two] \setupmixedcolumns[register][direction=reverse] \setupregister[index][ before=,after=, command=\MyCommand, alternative=b, color=red, ] \def\MyCommand#1{#1} %\def\MyCommand#1{\inframed[frame=no]{#1}} % this fixes the problem \showboxes \starttext \index{آب} \index{عذر} \index[تک]{TEX} testing \placeindex \stoptext Some of the setups are to refute suspected causes. Notice that using \inframed fixes the problem. Thanks, Hossein

Source very outdated
by Henri Menke 26 Aug '16

26 Aug '16

Dear list, I'm quite new to ConTeXt and have worked my way through a lot of documentation. The Garden is an invaluable source as well as this mailing list. Sometimes it occurs that a feature which is announced on the mailing list is neither documented in the Garden nor in some PDF. Then I proceed to browse the source where I found four resources: (1) local (for TeXlive in /usr/local/texlive/2016/texmf-dist/tex/context) (2) http://source.contextgarden.net/ (3) http://repo.or.cz/w/context.git (4) https://bitbucket.org/phg/context-mirror The first three are outdated and the last doesn't offer full text search. I could update the first source, but I don't want to break my existing setup and often I just look at the source to find out how things are implemented or to checkout whether a new feature is worth updating. It would be great if the online sources (2) and (3) could be updated. Another option would be to move the (4) from bitbucket to github, because github offers full text search in a repository (among other features, like continuous integration or gitter.im chatroom which are all free for an open-source project, see [1] for details). I'd love to hear what the elders of ConTeXt think about this. Cheers, Henri [1] https://github.com/integrations

Dear List, Last year, Hans helped me with this example: \starttext \startluacode local name = nil local temp = 0 function document.startwhatever(s) name = s temp = 0 end function document.addwhatever(n) temp = temp + n context(n) end function document.stopwhatever() job.variables.save("document:temp:"..name,temp) end function document.getwhatever(s) context(job.variables.collected["document:temp:"..s]) end \stopluacode \def\startwhatever[#1]{\ctxlua{document.startwhatever("#1")}} \def\stopwhatever {\ctxlua{document.stopwhatever()}} \def\addwhatever #1{\ctxlua{document.addwhatever(#1)}} \def\getwhatever #1{\ctxlua{document.getwhatever("#1")}} total: \getwhatever{foo} \startwhatever[foo] test 1: \addwhatever{10}\par test 2: \addwhatever{20}\par test 3: \addwhatever{30}\par \stopwhatever \stoptext However, on my current ConTeXt on Debian (2016.05.17.20160523-1), I am unable to get it working.

Pretty print Ctx code into HTML
by Lukáš Procházka 25 Aug '16

25 Aug '16

Hello, does anybody know about a tool (maybe ConTeXt has something like this built-in) which would convert ConTeXt code into pretty-printed HTML code? E.g.: ---- t.mkiv \starttext \foo[bar] baz \stoptext ---- to be rewritten into e.g.: ---- t.html <pre class="keyword">\starttext</pre> <pre class="keyword">\foo</pre><pre class="bracet">[</pre>bar<pre class="bracet">]</pre><pre> baz</pre> <pre class="keyword">\stoptext<pre> ---- Best regards, Lukas -- Ing.
