Subject: How to post-process the buffer populated by the async `start-process'
Date: Fri, 11 Jan 2019 22:34:53 -0500 [thread overview]
Message-ID: <CAFyQvY3a4y+u2V==e17e_Lxu9z5pm9JODQY9kfPLdeD-EWEoRg@mail.gmail.com> (raw)
Hello,
I am using a package which starts a command in a subprocess (async) using
`start-process' and the results of the command are dumped in the buffer arg
passed to subprocess.
But the stdout sent to the buffer has ANSI escape codes.
If I manually visit that buffer, and eval (ansi-color-apply-on-region-int
(point-min) (point-max)), I can see the ANSI color codes nicely rendered.
But I cannot figure out how to do that *when* the start-process initiated
command ends *in* the specified stdout buffer.
If I do:
(apply #'start-process ..)
(with-current-buffer buffer
(ansi-color-apply-on-region-int (point-min) (point-max)) )
.. it of course doesn't work because the a-c-a-o-r-i is getting called
before start-process initiated command ends.
So I somehow need to define a hook that can get triggered when that command
ends, and then call the a-c-a-o-r-i function. But I don't know how.
