Sebastien:
Thanks! That helps a lot. I'm having trouble extending your example,
however. A couple of questions --
- What signals the end of the block of text to be used as data? I take it
that it's important that these all be comment lines staring with a colon
after the #+name label? Is there a way to do the same thing with a begin
and end block construction?
- In this line:
#+begin_src sh :stdin lines-of-text :results output
does the flag :stdin mean that the following named block literally becomes
the STDIN stream for the code block? If I replace your shell/grep example
with this:
#+begin_src perl :stdin lines-of-text :results output
while (<>) {
print $_;
}
#+end_src
...it doesn't work, although as far as I know that perl code snippet should
in fact simply print out the incoming lines from stdin.
Thanks again,
Michael
