lei spawns mua before results are written

lei spawns mua before results are written

[Leah Neukirchen]

Hi,

I tried building some tooling to use lei with mblaze and stumbled upon
the fact that lei seems to spawn the mua before all mails are written
into the -o maildir; at least, adding a "sleep 1" in front of my
script fixes it.  Any way to wait for it? I guess I could just run lei
and my mua scripts afterwards.

Thanks,

Yes, it's intentional to allow Maildir and IMAP to allow MUAs to
work progressively while loading similar to how less(1) and
typical web browsers work.  It's not really practical to do for
mbox* because of locking and potential incompatible locking
protocols.

You should be able to use --alert=COMMAND to run any arbitrary
command(s) (including an MUA, as an alternative to --mua).

I'm not sure if adding a --no-early-mua switch is needed.  My
gut reaction is having yet another switch to document increases
the learning curve and support overhead...  *shrug*
