Hi,
I have a bit of a fancy bash prompt and so the output of evaluating a
block of shell script ends up a little messy:
#+BEGIN_SRC sh :session install :results output
echo blah
#+END_SRC
#+RESULTS:
: blah
: ]2;loris@soroban\a[35m[10:21:45] [31mloris@soroban [36m(1058) [33m/home/loris/tmp[34m[0m
Is there any way to avoid this short of resetting PS1 within the babel
session?
Cheers,
Loris

It looks like `org-babel-sh-strip-weird-long-prompt' removed the
prompt from the output. Your prompt doesn't match that regex? Maybe
redefine it there.

So this is what you are talking about:
(defun org-babel-sh-strip-weird-long-prompt (string)
"Remove prompt cruft from a string of shell output."
(while (string-match "^% +[\r\n$]+ *" string)
(setq string (substring string (match-end 0))))
string)
Bearing in mind that my pattern-matching experience is mainly from Perl,
I don't get the regex above. Isn't it just going to match a prompt
starting with a '%' followed by a bunch of spaces, carriage returns /
newlines, and more spaces? That may be both weird and potentially long,
but isn't it quite a specific subset of weird, long prompts?
Cheers,
Loris
