Multistandard PDF
by Robin Schwab 28 Feb '20

28 Feb '20

Hi, I am looking for a LaTeX system that can create accessible PDF so I tried ConTeXt. In current ConTeXt it seems to be impossible to specify more than one \setupbackend[format Minimal example: \setupbackend[format={pdf/a-3a,pdf/ua-1,pdf/x-4}] \starttext \input knuth \stoptext I get an error: backend > profiles > error, format 'pdf/a-3a,pdf/ua-1,pdf/x-4' is not supported Why should I have to choose whether my PDF is accessible to search engines, the disabled or the print-shop? Shouldn't everybody be able to access my document? Regards Robin

repeat a page inside a document
by Pablo Rodriguez 27 Feb '20

27 Feb '20

Dear list, I have the following sample: \starttext \input knuth \page[right] \setuplayout[page] \externalfigure[\jobname.pdf][page=1] \stoptext My question is how to get a page from the document you‘re compiling repeated inside the same document. I have tried to search both i-context.pdf and the wiki, but “mirror” and “repeat” seem to be bad options. Many thanks in advance, Pablo -- http://www.ousia.tk

European style Circuitikz error
by Jan-Erik Hägglöf 27 Feb '20

27 Feb '20

In page 8 inte e Circuitikz manual the settings to get European style components e.g resistors like rectangular boxes instead of default looking. It says this \usemodule[circuitikz][american] When I do this \usemodule[circuitikz][european] It gives an error. ! Package pgfkeys Error: I do not know the key '/tikz/short' and I am going to ignore it. Perhaps you misspelled it. So it must be some other way to set this, how do I make it possible? Thanks in advance /Janne

Problem with \setuparranging
by context＠vivaldi.net 27 Feb '20

27 Feb '20

Hello, I need to create a document where page arranging is mixed somhow - so that some pages are to be typeset "normally", some other placed "2 pages onto 1 page". All pages should appear as A3 size. A simplified code follows; its goal is: - page 1: to be one external figure of size A3 (red), - page 2: to be composed of one page of size A4 (green) on the left half, some text on the right half, - page 3: to be one external figure of size A3 (the same as on page 1) - page 4: to be composed of one page of size A4 on the left half, some text on the right half (as on page 2). The (unwanted) result is: - page 1: as expected, - page 2: as expected, - page 3: surprisignly A4 (red) (whilst the figure is of A3), - page 4: surprisingly A3, but some text on the left half, and no green A4. Is \setuparranging limited somehow or intended for another use? How to generate "Goal.pdf" instead of "t.pdf"? Best regards, Lukas

Error in MetaFun LMTX
by Jan-Erik Hägglöf 25 Feb '20

25 Feb '20

The following code gives an error, my goal is to draw 4 different arrows but only three functions successfully. The error log shows metapost > initializing number mode 'scaled' metapost log > metapost log > loading metafun, including plain.mp version 1.004 for metafun iv and xl metapost log > metapost log > >> unknown path D metapost log > ! Isolated expression. metapost log > <to be read again> metapost log > : metapost log > <*> ... :=(12cm, -1cm)--(11cm, -1cm); path D ; D : metapost log > =(4cm, -1cm)--(3cm, -1cm)... metapost log > And the code is as follows \startMPcode path A ; A :=(0cm, -1cm)--(1cm, -1cm); path B ; B :=(13.5cm, -1cm)--(14.5cm, -1cm); path C ; C :=(12cm, -1cm)--(11cm, -1cm); path D ; D : =(4cm, -1cm)--(3cm, -1cm); drawarrow A; drawarrow B; drawarrow C ; drawarrow D ; \stopMPcode Unless I uncomment D it gives the above error. Mysterious issue /Janne

Customizing \cite alternatives
by Philipp A. 24 Feb '20

24 Feb '20

Hi List, I want the comma gone from “et al.” citations, and modify the cite alternatives: - [authoryear]: (Surname, et al., 2018) → (Surname et al., 2018) - [authoryears]: Surname, et al. (2018) → Surname et al. (2018) Also I’d like to configure how many names are the maximum before all except the first are replaced by “et al.” i.e. \setupcitething[maxauthors=3]: (One, Two, Three, & Four, 2018) → (One et al., 2018) How can I do this? I didn’t find anything in the publications manual: http://pragma-ade.nl/general/manuals/mkiv-publications.pdf Best, Philipp

Accessing raw titles in textcommand in TOC
by alephzorro 22 Feb '20

22 Feb '20

Hello, I would like to display titles differently in TOC than they appear in text. For example, MyChapter1 -> 1retpahCyM. Basically any highly non-trivial transformation that really needs Lua. I've written simple Lua macros before, but the following approach trying to define textcommand does not work since I can't find the way to pass the raw title to my transform function. \startluacode userdata = userdata or {} function userdata.mytransform(title) --context(title) --this is just fine, but isn't very useful context(string.reverse(title)) end \stopluacode \def\transformtitle#1% {\ctxlua{userdata.mytransform([==[#1]==])}} \setuplist[chapter][textcommand=\transformtitle] \starttext \completecontent \startchapter[title={Sample Chapter}] \stopchapter \stoptext When I print the actual title that is passed to mytransform, all I get is \currentlistentrytitle and I haven't succeed expanding it (and there's all kind of formatting stuff and so on going on I suppose). Sections have "deeptextcommand" which is somewhat what I'm after here, but I've not found similar option for TOC. So, is there a way to get just the raw titles? Jason C.
