Matching tasks look&feel?
So what is eventually agreed for all matching tasks to look like?
We have two cases:
a) task takes a single file (or directory) as an argument,
and the user wants to specify it directly.
b) the task takes a list of files which is build from a directory and
constrained by include/exclude pattern.
Thus we have two major options:
1. "Strict-typing"
a) <task file="file.dat" .... />
b) <task dir="dir" .... includes="*.dat" />
2. "Dynamic-typing"
a) <task src="file.dat" .... />
b) <task src="dir" .... includes="*.dat" />
It is obvious that for 1. any of the below does not make sense,
and need to throw a build exception (i would think):
a)
<task file="dir" .... includes="*.dat" />
<task file="file.dat" .... includes="*.dat" />
b)
<task dir="file.dat" .... />
Any other options?
I do not have very strong opinion about it, however I like 2. a little
more.. if people are more into explicit things, 1. is fine with me as
well... but I suggest we agree on one, and make all tasks uniform ;o)

Hmm, this sounds like a good idea, IMHO. That is the way the UNIX/Linux
commands work:
rm -R /home/ernst/tmp
ls -R
chmod -R a+r *
So I'd say don't distinguish between files and directories, and just add
an attribute `resursive' or `recurse' and set the default value to
`false'.
A +1.01 vote for me :)

In case of the delete task I'd really prefer to have an distinction
between dir and file because of the damage one could do by accident -
only alternative I see is a recurse attribute with default false.
Then take a look at your own patch to Chmod. You support a chmod on a
directory without recursion by <chmod file="dir" ... /> and a recursive
one by <chmod dir="dir" ... />. Without different attributes you would
need includes/excludes if you only want to affect the top dir.
Therefore I'd prefer strict-typing (but you could see this a a -0.5 if
I were to vote).
