Re: [O] babel, executing code in background process
Hello! The trick would be in setting up the post-execution code block handling (namely results parsing and insertion) to run after external evaluation has completed. I don't think this is a high priority necessarily. When executing e.g. gnuplot or octave source code blocks for the sake of plotting, I'm usually interested in runtime feedback more than collecting the text afterwards. When doing notebook-Style work, also something like : #+begin_src octave :session *foo* :results silent asynchronous-header : Calculate data : #+end_src : #+begin_src octave :session *foo* :results value synchronous-header :Return data : #+end_src would be possible, though of course no convenient solution. My current solution for long-running octave scripts isn't any more convenient though: Define the task as functions and then switch to the session buffer manually and run those interactively. kind regards, Yu 2012/3/2 Eric Schulte eric.schu...@gmx.com Erik Garrison erik.garri...@gmail.com writes: Hi Eric, Thanks for the background.

The approach you describe above (a process buffer with a filter) would be one viable approach, perhaps even something as simple as using `async-shell-command' would be workable.
