Placement of floats
by Willi Egger 13 Jan '22

Hi all, here follows the compilation of the example-file, this time I replaced the dummy-figure with a simple \framedtext in order to comply with the 100kB rule of the mailing-list. I added a black line at the bottom with “Preview” on Mac OSX , so the problem is visible immediately. Kind regards Willi

\sub conflict with my def
by Gavin 13 Jan '22

13 Jan '22

Hi List, I am converting problem sets from LaTeX to ConTeXt and ran into a puzzling problem. I define \sub to produce subscript text in math mode. (See definition below.) This worked for my ConTeXt book, but fails in the problem sets because in ConTeXt \sub is a special item command, and I use itemize to number problems. Obviously, I can rename my \sub command, but it is already used in hundreds of problems and solutions that I am converting. Is there a way to get my \sub to work in an itemize? I only need it in math mode. I will never use \sub for its ConTeXt itemizing purpose. Thanks! Gavin \define[1]\sub{_{\text{\rm\tf#1}}} \starttext $E\sub{final}$ is the final energy, but not in an itemize: \startitemize \item $E_{\text{\rm final}}$ is the final energy. \item $E\sub{final}$ is a mess. \stopitemize \stoptext

Wiki: new commands not automatically available for autogenerated syntax (was LTR footnotes from RTL paragraph)

Hi, I wanted to wikify a new command, but I don't fully understand what to do... > -----Ursprüngliche Nachricht----- > Von: Hans Hagen <j.hagen(a)xs4all.nl> > Gesendet: Donnerstag, 13.

And, the new option for \setupalign does not show up in the autogenerated syntax overview at https://wiki.contextgarden.net/Command/setupalign I probably don't fully understand how the wiki works in these regards .. can anyone clarify?

Conditional text appearing in a fixed vertical space
by Gavin 13 Jan '22

13 Jan '22

Hello List, I am making problem sets for a physics class. Solutions use the style defined in the example below, and only appear if the “solution” mode is enabled. I am struggling to get a vertical space for the solution which is the same whether or not the solution is printed. Different problems require different amounts of space, so this should be an argument or key-value. In the example below, the first solution has the desired behavior. The second solution has the syntax I’d like, but it doesn’t make the space without a solution. Any ideas would be welcome! I am still pretty new to ConTeXt, so I struggle mixing things like the plain tex \vbox and ConTeXt \start…\stop concepts. Thanks, Gavin \definemode[solution][yes] % yes to enable solutions, no to disable \definebuffer [solution] % Captures solution in a buffer that isn't used \startmode[solution] % If in solution mode, redefine \startsolution...\stopsolution \definedelimitedtext[solution][ % Solution italic and indented spacebefore=medium, spaceafter=medium, style=\rm\it, leftmargin=standard, % Indents block on the left rightmargin=yes, % Indents block on the right indentnext=no, before=\vbox to 1in\bgroup, after=\egroup, ] \stopmode \starttext How many roads? (The 1-inch space below appears whether or not it contains a solution.) \vbox to 1in{% \startsolution 42 roads. \stopsolution } How much wood? (I would like to define solution so this to behaves like the previous question.) \startsolution[1in] Alotta wood! \stopsolution No more questions. \stoptext

LTR footnotes from RTL paragraph
by denis.maier＠unibe.ch 13 Jan '22

13 Jan '22

Hi Footnotes originating from an RTL paragraph will be also typeset in RTL mode as the following example illustrates: %%%%%%%%%%%%%%%%%%%%%% \setupdelimitedtext[blockquote] [leftmargin=1.5em,rightmargin=0em,] \definedelimitedtext[rtlblockquote] \setupdelimitedtext[rtlblockquote] [leftmargin=0em,rightmargin=1.5em,before={\righttoleft}] \starttext \input knuth \startblockquote \input knuth\footnote{this starts on the left.} \stopblockquote \startrtlblockquote \input knuth\footnote{this should start on the left, but it doesn't.} \stoprtlblockquote \input knuth \stoptext %%%%%%%%%%%%%%%%%%%%%%%% According to the wiki, that's the expected behaviour (https://wiki.contextgarden.net/RTL#Footnotes) However, I'd prefer to keep the footnotes as LTR footnotes. Can I convince ConTeXt to typeset these footnotes in LTR mode? Best, Denis

Radius attribute and scaling in lmt_shade[ ]
by Keith McKay 12 Jan '22

12 Jan '22

Hi In the code below you will see that I have created a closed path and performed scaling, and shading on the path with lmt_shade [ ]. I have noticed a few features which may or may not be bugs depending on whether scaled is applied to the path within the square brackets or outside. 1) Applying scaled to the path within the square brackets and incrementing the radius key I can see the shaded areas changing, however the first two shapes show incorrect scaling and have ragged edges. 2) When scaled is applied outside the square brackets all shapes are the same size and no ragged edges, however the shading is not showing correctly with increasing radius. Am I missing something?

Critical Editions?
by hanneder＠staff.uni-marburg.de 11 Jan '22

11 Jan '22

I just started switching after long years of typesetting with La-/Omega-/pdfTeX to Context and was exploring the capabilities of the program for typesetting critical editions. So I was wondering whether there is any updated information on how to produce critical editions? Details: I was able to find the article "Ediciones críticas con ConTeXt" (is this in use?) as well as a plan of and a remark concerning critTeXt: "As I learned from a thread on NTG-context from early 2010 we shouldn't expect a dedicated package, but that ConTeXt will eventually incorporate the needed functionalities." What is the status of that? I also found out that for simple editions context already works. For critical editions in my field we need both footnote references based on linenumbers (for prose), but also references to verse number, which can be entered manually. The main problem for me was to find the command \linenote :) % Setup of \linenote \setupnotation[linenote] [alternative=serried,width=broad,distance=.5em,display=no] \setupnote[linenote][way=bypage,paragraph=yes,rule=off] % \variant as a footnote without reference number \definenote [variant] [footnote] \setupnotation[variant][number=no] \setupnote[variant][way=bypage,paragraph=yes,rule=off] % Two "environments" for Sanskrit verses, one with, one without linenumbers. % SANSKRIT EDITION linenumbers \definelines[slokaed][][indenting={yes, small, even}, before=\startnarrower\startlinenumbering,after=\stoplinenumbering\stopnarrower] % SANSKRIT EDITION plain (referring to verses) \definelines[slokaedplain][][indenting={yes, small, even}, before=\startnarrower,after=\stopnarrower] With this the code of the edition can be pleasently minimalistic: \startslokaed mano buddhir ahaṃ prāṇās tanmātrendriyajīvanam yaṃ dṛṣṭvā\linenote{dṛṣṭvā ] dṛṣṭva G\lohi{pc}{1}} vinivartante tam \linenote{tam ] tat} upāsyam upāsmahe} \stopslokaed \startslokaedplain mano buddhir ahaṃ prāṇās tanmātrendriyajīvanam yaṃ dṛṣṭvā\variant{2c dṛṣṭvā ] dṛṣṭva} vinivartante tam \variant{2d tam ] tat} upāsyam upāsmahe (2) \stopslokaedplain So far, so good. Any hints to a more sophisticated solution are highly welcome. (I am a simple TeX user) Thanks Jürgen --- Prof. Dr. Juergen Hanneder Philipps-Universitaet Marburg FG Indologie u.

How to setupbtx to get short citations?
by Mikael Sundqvist 11 Jan '22

11 Jan '22

Hi, In the example below I can do \cite[short][hh2010] to get the citation in the short format. But I thought that would also be the standard with \setupbtx[aps][alternative=short] (so that I can write \cite[hh2010] instead). What do I miss? (Except for the fact that I should probably define my own btx style as a copy of aps instead of setting the aps up...) /Mikael \startbuffer[bib] @ELECTRONIC{hh2010, author = {Hans Hagen}, year = {2010}, title = {Metafun. \CONTEXT\ mkiv}, url = {http://www.pragma-ade.nl/general/manuals/metafun-s.pdf}, } \stopbuffer \usebtxdataset[bib.buffer] \usebtxdefinitions[aps] \setupbtxrendering[aps][ sorttype=short, numbering=short, ] \setupbtxlist[aps][ width=fit, distance=0.5em, interaction=start, ] \setupbtx[aps][ alternative=short, ] \starttext \cite[hh2010] \placelistofpublications \stoptext

How to let a macro check the previous value of #1 the last time the same macro was called?
by Joel 11 Jan '22

11 Jan '22

Is there a way for a macro to check the previous value of #1, the last time that same macro was called? Here is a minimum working example, pretending that `\previousvalue` is equal to #1 from the last time the same macro was called: \define[1]\mymacro{ \if\previousvalue=#1 same as last time \else it is different from last time \fi } \starttext \mymacro{cat} \mymacro{cat} \mymacro{mouse} \mymacro{mouse} \mymacro{cat} \stoptext This would print: it is different from last time <--it was never called previously same as last time it is different from last time same as last time it is different from last time --Joel
