[Jython-dev] FW: AUT / Ant Utility Toolkit

[Phil S. <psu...@es...>]

I thought you guys might be ineterested in this
for extending os support (pipes etc.). I haven't
looked into it myself though.

Hi,

I just created a new package hierarchy org.apache.aut* in which I was going
to place sanitized code that is not directly tied to ant. For instance a lot
of the infrastructure would be very useful in contexts outside ant. Examples
would be a clean API for

+ native executable launching
+ getting native OS environment variables
+ getting native OS data
+ javac functionality (mainly used in recompiling frameworks like
jasper/cocoon)
etc.

Anyways I have just started to move stuff there. My first move was the
native
execution stuff. The way I designed it was that you essentially create an
instance of ExecMetaData filled with all the parameters you want to use to
launch executable and then you pass this to ExecManager which does all the
work. I have also moved th Os class and created an Environment class to load
native environment.

Theres still a few holes or dependencies on original ant stuff but I am
starting to like the look of it overall. I would be interested to hear any
opinions on the construction of it. Basically I tried to minimize the amount
of work user will have to do (ie see ExecOutputStream and compare with the
old method).

Anyways this is just the start. Theoretically it could even be reintegrated
back into Ant1.x - but you would need to create a new instance of
ExecOutputStream that played better with ants current logging
infrastructure.

* yes aut package was previously used for Avalon Utility Toolkit and before
that Apache Toolkit but no code was released under that package name
