This patch is for python mode. Recently Python 3 added the “async” keyword for functions like so:

def this_is_not_async():

pass

async def this_is_async():

pass

The mode has already been updated to recognize this for most things, but not imenu. It currently would show:

this_is_not_async (def)

def (async)

The patch below is a minor modification for a regular expression. The old one simply took the 2nd token on the line to be the name; the new one skips the optional “async” keyword.

Please note the current imenu is unusable in a file with a lot of async functions - it would be nice if this rolled out with 25.2 if possible, which I believe adds the rest of async support.

Thanks,

Michael Kleehammer
