[9fans] Using Acme as an external Editor

[9fans] Using Acme as an external Editor

[Aaron W. Hsu]

Hello,

Is there some idiom or method for using Acme as an external editor to some
other program? Say I want to use it as the editor that is spawned when I
do a CVS commit to a system; how would I do this, or can this even be
done? I'm using plan9ports, but I don't know how much of this question
relates to what.

Take a look at B, which can be used to send a file
to acme.  Also you may want to familiarize yourself with plumb.

That doesn't work because B ends after it plumbs the file to acme. CVS
will think that you're done. You need some

E calls B, but sleeps until the file has been modified.

For what its worth, when I started using CVS on plan9
I trained myself to add a -m 'text' after every cvs ci
command.

I also added a -e false (where false is non-existant)
to my $home/lib/cvsrc so I can still omit the -m and
commit stuff with no log message...

I was playing with this exact problem recently. There's an easy way to
send a file to acme for editing -- the plumber.  There's a downside, it
doesn't wait for the editor to save or complete.  So.. you could plumb the
file and then wait for a save to happen, somehow, or you can write another
program that forces a new acme window with the contents of the file and
waits for it to either Put or Del.  I wrote a small program to do this
recently (see the thread: http://9fans.net/archive/2009/06/290) which was
a bit hacky, but worked.  I solicited some feedback on some questions and
got some good advice from Russ (http://9fans.net/archive/2009/06/292) but
havent yet gone back and applied it.

I don't think you need to be that fancy.
Lorenzo Bolla already pointed out E in this thread,
and it exists exactly for this purpose.

One caveat about E: if you're paranoid like I am and save your file
many times while editing, E will not be terribly friendly until you
train yourself to save only when finished. (This is not a criticism of
E, it is merely a warning to people with my kind of idiosyncrasies)

 Heh, I do this too. Ended up writing
http://sqweek.dnsdojo.org/plan9/acmeedit which also adds a Cancel
option so you can end the editing session with a non-zero exit (used
by some callers to abort the operation).

You are a lifesaver.
