Hi all,
Is it possible to run a ruby script from a context document during its
processing (I already know how to do that using \write18 but there is
maybe a better way...) then get the output of the script to display or
use it into the document. It's a little bit hard to describe so I have
a simple example:
\starttext
\def\vartest{3.124325234543523452435}
\write18{ruby ./myscript.rb \vartest
X}
\stoptext
with myscript.rb:
temp = ARGV[0]
puts \nX + (Math::sqrt(temp.to_f)).to_s +
X\n
I would store the result of puts into a variable usable within ConTeXt...
piping: the latest versions of pdftex support this (i\ve forgotten the syntax,
but taco who wrote the patch may remember)
you can also let ruby write a definition to a file temp.tmp which you can read
in
however, luatex can do:
\edef\SomeVar{\lua{tex.print(math.sqrt(3.124325234543523452435))} or
\def\GimmeARoot#1{\lua{tex.print(math.sqrt(#1))}
actually, this is one of the examples i use in prelim demos at user group
meetings -)
so, be a bit patient and it will come your way ...
