And then follows the quoted reply. I do have a discrete sensation this is locale specific though which makes me a sad programmer.

The reason I ask for this is because roundup doesn’t strip these correctly when replying through gmail to an issue. And I think origmsg_re is the config.ini variable I need to set alongside keep_quoted_text = no to fix this.

Right now it’s the default origmsg_re = ^[>|\s]*-----\s?Original Message\s?-----$

Edit: Now I’m using origmsg_re =
^On[^<]+<.+@.+>[ \n]wrote:[\n] which works with some gmail clients that break lines that are too long.

Answer 1

The following regex will match gmails prefix in a pretty safe manner. It ensures that there are 3 commas and the liter text On … wrote

On([^,]+,){3}.*?wrote:

If the regex should match in a case insensitve way then don’t forget to add the modifier.

if re.search("On([^,]+,){3}.*?wrote:", subject, re.IGNORECASE):
    # Successful match
else:
    # Match attempt failed

Match the characters “On” literally «On»
Match the regular expression below and capture its match into backreference number 1 «([^,]+,){3}»
   Exactly 3 times «{3}»
   Note: You repeated the capturing group itself.  The group will capture only the last iteration.  Put a capturing group around the repeated group to capture all iterations. «{3}»
   Match any character that is NOT a “,” «[^,]+»
      Between one and unlimited times, as many times as possible, giving back as needed (greedy) «+»
   Match the character “,” literally «,»
Match any single character that is not a line break character «.*?»
   Between zero and unlimited times, as few times as possible, expanding as needed (lazy) «*?»
Match the characters “wrote:” literally «wrote:»
