[NTG-context] reading from standard input

2012-06-08 Thread stdin | Alexandre Leray 

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

you can use the standard tex input readers (\read) as well as io.read 
when you're in lua

You can try context --pipe --result=/tmp/result.pdf but that only runs the 
document once, so cross referencings, TOC, etc won't work correctly. The 
other options is to write to a file, and then run context --purgeall 
--result=/tmp/result.pdf filename; this will run the document appropriate 
number of times, and then delete the temp files, leaving only the .tex and 
the .pdf file.
