\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

Evaluating a Lua expression at the end (repeat)
by Kumar Appaiah 26 Aug '16

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. It says: lua error > lua error on line 37 in file /tmp/test.tex: /usr/share/texmf/tex/context/base/mkiv/core-uti.lua:165: attempt to index upvalue 'tobesavedmacros' (a nil value) stack traceback: /usr/share/texmf/tex/context/base/mkiv/core-uti.lua:165: in function 'save' [ctxlua]:14: in function 'stopwhatever' [ctxlua]:1: in main chunk 27 \def\getwhatever #1{\ctxlua{document.getwhatever("#1")}} 28 29 total: \getwhatever{foo} 30 31 \startwhatever[foo] 32 33 test 1: \addwhatever{10}\par 34 test 2: \addwhatever{20}\par 35 test 3: \addwhatever{30}\par 36 37 >> \stopwhatever 38 39 \stoptext 40 41 Could you please suggest a workaround?

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.

APA formatting and reference questions
by Todd DeVries 25 Aug '16

25 Aug '16

Hello, I would like to use ConTeXt foracademic writing this year and am just scratching the surface of its capabilities. My first run at producing a document in APA format resulted in several questions. Below is abrief sample. In this excerpt, the following APA style formatting errors occur: 1. The first reference is cited as “Hartley, M.T. (2013).” There is usually a space separating these initials. Between the M. and T. in this reference. 2. The word “and” is appearing in both parenthetical and in-text citations. When a reference is completely within parentheses, the last author should be separated by the & (Ampersand) character. 3. The last reference has 3 authors and should be written as Koch et al (2014) instead, it replicates the entire list of authors previously cited. I must be missing something obvious in my settings. What changes to this sample need to be made to correct these formatting citation errors? Thank you in advance for any assistance or references to places in documentation where I can learn to correct these issues.
