Re: Running ant in loop mode

Hello all,
...
The initial idea would be to add a command line parameter (-loop) to ant, so 
it can run in loop mode. 
...
With this patch, the new tasks are executed really fast
...
I improved the patch a 
little bit: now the Main class has 2 new attributes, loopMode and 
loopHandler, which could be set by the IDEs. LoopHandler is a new interface, 
whose default implementation uses System.in.read().
...
So, what do you guys think of the patch? I think it would be really useful, 
and easy to implement (of course, if I didn't think so I wouldn't suggest it 
:-). If it is accepted, I could offer more help documenting and testing it 
(personally and with the participation of folks at my company and JUG).
I'm not an Ant committer, but a heavy Ant user, and I can say that I 
really like it :-)

It's months that I wanted this but really never got round doing it, and 
I'm happy that someone else has done it.

I would add a couple of suggestions if you don't mind, as I would 
basically keep -loop as now but would be thrilled to se other features 
very similar to it:

1 - it would really be nifty if there was also an -interactive mode,
    where a special LoopHandler is able to read also a new target
    invocation
2 - also having a LoopHandler to accept the tasks to run via
    socket (it can be easily implemented when 1 is done)
So when 1 is done, it would be:
ant -loop targetname
Buildfile: build.xml
targetname:
     [...] ...
BUILD SUCCESSFUL
Total time: 2 seconds // first evocation, took 2 seconds
Press Enter to continue
      q + Enter to quit
      targetnames + Enter to change invocation
>target3 target4 (Enter)
Buildfile: build.xml
target3 :
     [...] ...
target4 :
     [...] ...
BUILD SUCCESSFUL
Total time: 3 seconds // first evocation, took 3 seconds
Press Enter to continue
      q + Enter to quit
      targetnames + Enter to change invocation
>(Enter)
Buildfile: build.xml
target3 :
     [...] ...
target4 :
     [...] ...
BUILD SUCCESSFUL
Total time: 1 seconds // first evocation, took 3 seconds
Press Enter to continue
      q + Enter to quit
      targetnames + Enter to change invocation
>q(Enter)
$>_
