markdown module vs pandoc
by Gour 24 Feb '19

24 Feb '19

Hello, I'm interested for using markdown markup and typeset such documents via ConTeXt, but wonder whether it is recommended to use Markdown module or do markdown --> ConTeXt via Pandoc? Sincerely, Gour -- Thus the wise living entity's pure consciousness becomes covered by his eternal enemy in the form of lust, which is never satisfied and which burns like fire.

\setupmathematics with stylealternative not working
by Mikael P. Sundqvist 24 Feb '19

24 Feb '19

Hi, It seems that, with the latest beta, the \setupmathematics with stylealternative is not working. I tried \setupbodyfont[lucidaot] \setupmathematics[stylealternative={calligraphic}] \starttext \startTEXpage[offset=3bp] $\mathcal A$ \stopTEXpage \stoptext and got the attached output lcm.png. This is not the curly A I would expect. The one I expect is the one that can be seen on top of page 9 in https://tug.org/store/lucida/lucida-amsmath.pdf. I also noticed that the example file that I have seen earlier on this list, pasted below, does not seem to change anything. Has anything changed? /Mikael % second example \setupbodyfont[lucidaot] \starttext $x ^{i \leftarrow 0 = ∅} _{\setmathfontalternate{arrow} \setmathfontalternate{dotless} \setmathfontalternate{zero} i \leftarrow 0 = ∅} $ $x ^{i \leftarrow 0 = ∅} _{\setmathfontalternate{arrow,dotless,zero} i \leftarrow 0 = ∅} $ \setupmathematics[stylealternative={arrow,dotless,zero}] $x ^{i \leftarrow 0 = ∅} _{i \leftarrow 0 = ∅} $ \stoptext

With the following example, I get: ...eXt/tex/texmf-context/tex/context/base/mkiv/grph-inc.lua:238: attempt to call upvalue 'imgwrap' (a nil value) with the current (20190222) beta. \setupexternalfigures[location=default] \starttext \externalfigure[cow.pdf] \stoptext Down for just me, or for everyone? -- Rik

When newsizing an external figure bei [width=<some pt>], what will be its height in pt and viceversa?
by Rudolf Bahr 23 Feb '19

23 Feb '19

Hi All, from an external figure I normally know its width and height in px. But I don't know its exact sizes in pt. When newsizing the figure in a document (by the same width-to-height-ratio), I'll do that as some part of textwidth or textheight, in pt or mm, but not in px, i.e. by means of [width=<some pt>]. Sometimes it would be interesting to know its new height in pt, and viceversa. Is there a variable or something else containing its new size in pt? Regards, Rudolf

getdocumentargument in Metafun
by Fabrice L 22 Feb '19

22 Feb '19

Dear list, I wish to do several zoom from a picture made in MetaFun, from a pdf file which name is given on the commande line, like: context zoom.tex —File=EntryFile —Page=9 —result=OutFile.pdf Minimal example: \starttext \startMPpage numeric ThePage ; string FileName ; FileName := \getdocumentargument{File} ; ThePage := \getdocumentargument{Page} ; draw textext("\externalfigure[" & FileName &"][page=" & ThePage &"]") xysized (48in,48in) ; \stopMPpage \stoptext I can get in the MPpage the page number in entry (9 in my example), but not the file name. Thanks for any help. Fabrice.

Pretty printer for matlab
by Otared Kavian 21 Feb '19

21 Feb '19

Hi all, Is there a pretty printer file to typeset Matlab codes? Actually I would like to modify such a file in order to define a typing environment to typeset portions of codes written for Scilab, which is a sort of free version of Matlab. Thanks for any comment and help: OK

Re: [NTG-context] troubles with \MPinclusions (Taco Hoekwater)

Thanks for your answers, I could significantly reduce my long timeline code. > 1. Variable names x and y are special and cleared before > every graphic. This is related to the fact that “z" is > defined as a shortcut for "(x,y)”. Both of these are > traditional. > > Every metapost graphic does at least this at its start: > > save x,y; > currentpicture := nullpicture; > currentpen:=defaultpen; > > so pair xx[]; would have worked just fine. > > In general, I would advice to stay away from single-letter > variable names inside MPinclusions, and use CamelCase > to avoid clashes with metafun internals. > So, got one more z-related error in Metapost. I bet this is absolutely the n.1 on help-lists. Btw, if I were a scientist, I'd realized that defining x as a pair is quite heretic… And that sounds much familiar to an historian. Damien Thiriet

troubles with \MPinclusions
by Damien Thiriet 21 Feb '19

21 Feb '19

Hi, Why does (1) compile, whereas (2) doesn't? I can't understand why can MPinclusions store path and not pairs. %%%%%%%%%%%% (1) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \setuppapersize[A4,landscape] \startMPinclusions u:=1mm ; %fond path p ; p:= (0,0) -- (150u,0) -- (150u,95u) -- (0,95u) -- cycle ; pair x[] ; x[0]:= (20u,90u) ; x[1]:= (40u,90u) ; x[2]:= (90u,90u) ; x[3]:= (140u,90u) ; \stopMPinclusions \startreusableMPgraphic{test} draw p ; \stopreusableMPgraphic \starttext \reuseMPgraphic{test} \stoptext %%%%%%%%%%%% (1) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \setuppapersize[A4,landscape] \startMPinclusions u:=1mm ; %fond path p ; p:= (0,0) -- (150u,0) -- (150u,95u) -- (0,95u) -- cycle ; pair x[] ; x[0]:= (20u,90u) ; x[1]:= (40u,90u) ; x[2]:= (90u,90u) ; x[3]:= (140u,90u) ; \stopMPinclusions \startreusableMPgraphic{test} draw p ; for i=0 step 1 until 3 : drawdot x[i] ; endfor ; \stopreusableMPgraphic \starttext \reuseMPgraphic{test} More generaly, which kind of variables cannot be stored in \startMPinclusions ?
