reading from standard input

Hi, I was wondering if there was a way to make context read from stdin instead of reading from a file? cat /path/to/src.tex | context --result=/path/to/result.pdf I'd like to do something like this in python: def generate_pdf(self): src = """ \starttext \section[éléments-de-transmission]{Éléments de transmission} Un module dans lequel une communauté temporaire d'étudiants et d'enseignants s'exerce à mettre en situation des réflexions et des moments de transmission en interrogeant sans cesse la question de l'enseignement. La configuration des enseignants est variable selon les situations. Les situations seront mises en place en semaine A et B selon l'emploi du temps. Chaque nouvelle situation invente sa méthode. \stoptext """ cmd = 'context --result=/tmp/result.pdf' p1 = subprocess.Popen(cmd.split(" "), stdout=subprocess.PIPE, stdin=subprocess.PIPE) (stdout, stderr) = p1.communicate(stdin=src) Thanks, Alex -- Alexandre Leray media& graphic design http://stdin.fr | http://osp.constantvzw.org/ rue Gallaitstraat 80 1030 Bruxelles +32 (0)4 87 04 70 30

conditional format of headings
by Jan Pohanka 08 Jun '12

08 Jun '12

Hello, is it possible to have some "conditional format"? I mean I'd like to have different vertical spacing for \section and \subsection when they follows immediately each other and when there is some text between them. best regards Jan -- Tato zpráva byla vytvořena převratnou poštovní aplikací Opery: http://www.opera.com/mail/

Confused again :-)
by Bill Meahan 07 Jun '12

07 Jun '12

I'm getting a handle on page layout and headings but there are some things I haven't figured out. 1) How does one specify they want the "outer" margin to be a different size than the "inner" margin? "Outer," of course, is the right margin on a right-hand (odd) page and the left margin on a left-hand (even) page. 2) How does one put a frame around a margin? Layers? Overlay? \framedtext? 3) Am I correct I can use the "COMMAND" parameters in \setuplayout to specify there is some text to use as a marginal in the (chapter | section) header (using \margintext, I presume)? I am working on a couple of novels I want to typeset using ConTeXt since I think it will allow me to produce what I want for typographic style much easier than using LaTeX. I'm pretty adept at using LaTeX but brand new to ConTeXt. One of _my_ problems is so many examples on the wiki seem oriented towards people setting math which could not be farther from my intended usages. (Not that I'm unfamiliar with math, I have a degree in Physics and would have had a double degree in math except for a choice to take a different course (helpful in physics) instead of one mandatory for the math degree).

expansion and \processaction
by Philipp Gesang 07 Jun '12

07 Jun '12

Hi all, my goal is a macro \definestates[foo][...,...] which takes a comma list and creates a monadic macro \foo[n]. \foo[n] should return either the nth item or, if (n > list length), a default. I thought the right tools were \processcommalist to generate the mapping n-><list item>, as well as \processaction to retrieve the items. But naively I didn’t consider expansion ... My code so far: ··8<···································································· \unprotect \def\definestates{\dodoubleempty\do_define_states} \def\do_define_states[#1][#2]{% \expandafter\edef\csname#1_states\endcsname{% \nstates0 %% this is supposed to be expanded so we employ the \raw... variety \rawprocesscommalist[#2]\add_one_state% unknown=>\dummystate,% default=>\dummystate,% }% \do_do_define_states{#1}% } \let\dummystate\empty \newcount\nstates \unexpanded\def\add_one_state#1{% \advance\nstates\plusone \the\nstates=>#1,% } \def\do_do_define_states#1{% \expandafter\def\csname#1\endcsname {\expandafter\dosingleempty\csname do_#1\endcsname}% \expandafter\def\csname do_#1\endcsname[##1]{% \iffirstargument % <[DBG] cmd:#1, state:##1>\par \edef\currentstates{\csname#1_states\endcsname}% %% At this point \currentstates should yield the whole mapping so %% we can use it with \processaction. But ... % \show\currentstates % \currentstates\par %% ... here it still contains %% \nstates 0 \rawprocesscommalist [foo,bar,baz] ... %% and the next directive has an empty result: \rawprocessaction[##1][\currentstates]% \fi }% } \protect \starttext \definestates[mystates][foo,bar,baz] %% At this point I’d like \mystates_states to contain (literally) %% “1=>foo,2=>bar,3=>baz,unknown=>,default=>,” %% so the following command \mystates[1] % -> foo %% would be equivalent to %% \processaction[1][1=>foo,2=>bar,3=>baz,unknown=>,default=>,] \mystates[2] % -> bar \mystates[42] % -> dummy \stoptext ··8<···································································· My question: How can I use \[raw]processcommalist in an expanded definition? How can I get \[raw]processcommalist to operate on the expansion of its second argument? Does this even make sense? If not, what is the proper way? I’d be grateful for any advice Philipp PS: Yeah, I could use Lua for it but that’s not the question.

multi-page floats
by Henning Hraban Ramm 07 Jun '12

07 Jun '12

Hi again, in my current book project there are sets of full-page graphics, where there’s first a drawing, to be printed on transparent paper, followed by a water colour picture as background, i.e. a series of right page: foreground graphic right page: background graphic The transparent pages are left out in pagination. Between chapters (i.e. stories), the following macro does what I want: \def\DoublePic#1{ \page[right] % foreground picture on transparent paper \setuppagenumbering[state=stop]\setuppagenumber[state=stop]\par \resetlayer[bg] \setlayer[bg]{\externalfigure[#1-fore][height=\dimexpr(\paperheight +6mm)]} \setupbackgrounds[page][background=bg] \strut\par % page needs some content \page[right] % background picture on normal paper \setuppagenumber[state=start]\par \resetlayer[bg] \setlayer[bg]{\externalfigure[#1-back][height=\dimexpr(\paperheight +6mm)]} \setupbackgrounds[page][background=bg] \strut\par \page \setuppagenumbering[state=start] } Now, the publisher would like to move the picture pages in the middle of the stories, i.e. I need them to float "here" without manual page breaking. How can I achieve that? I’d also appreciate enhancements to my macro above. (MkIV latest beta on OSX Intel.) Thank you very much in advance!
