automate command after saving

automate command after saving

[Martin Kaffanke]

Hi there,

I'd like to run a command after saving, but just if I switch it on.

Following scenario:

When I write on  an org file, before printing I look at the pdf version
created by

pandoc -t latex -o filename-without-org-but-with.pdf filename.org

And then I switch to emacs to do corrections.

Now I'd like to automatically run pandoc again when I switch back to
evince (which automaticaly loads the pdf new when changed on disk).

How could a make a switch for emacs to automatically run pandoc again
after C-x C-s?

Thanks for your Ideas,
Martin

You could do this using after-save-hook. So, something like

(add-hook 'after-save-hook
          'pandoc-hook)

(defun pandoc-hook()
  (compile "pandoc -t latex...."))

Personally, I do this outside Emacs, though, with this little bash
script.

#!/bin/bash
make $*
while inotifywait -r -e MODIFY --exclude ".#*" --exclude ".*~" .
do
    make $*;
done;

Cheap, cheerful but effective.

You could also use focus-out-hook to run the compilation each time you
/leave Emacs/.

Hth,

That sounds interesting, but is this a 'per buffer hook' or something?
Maybe I find out a possibility to automatically create the pathes too
and do a trigger-hook so I can switch it on or of on a specific buffer.
But this seems to be a good start.

Your bash script is also interesting, but as this is mosty required on
org-attachments, the path is not really human guessable, so its better
to have it out of emacs.

Thanks,
Martin

Hooks can usually have a global and a buffer-local value. See the
documentation for `add-hook' for details.
