This patch is for python mode. Recently Python 3 added the “async” keyword for functions like so:
async def this_is_async():
The mode has already been updated to recognize this for most things, but not imenu. It currently would show:
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.
