Hi Ken,
Sounds very cool and useful. Maybe you could make it into a Nant task and
submit it for consideration to the contrib project. I went a little more low
tech using a foreach and uptodate tag. Here is what I ended up with. It
surprisingly works well... not surprisingly it is a bit slow. But, that's ok
for now. Of course, it doesn't handle deletes... but that is fine... I needed
this to build a "hotfix" which only includes the newer/added files.
<foreach item="File" property="filename">
<in><items basedir="${ReleaseDir}"><include
name="**"/></items></in>
<do>
<property name="filename.tocompare"
value="${string::replace(filename,path::get-full-path(ReleaseDir),path::get-full-path(ReleaseDir.Rev0))}"
/>
<uptodate property="filename.uptodate">
<sourcefiles>
<include
name="${filename}" />
</sourcefiles>
<targetfiles>
<include
name="${filename.tocompare}" />
</targetfiles>
</uptodate>
<echo message="File ${filename} has been
updated" unless="${filename.uptodate}" />
<copy todir="${InstallDir.HF}"
unless="${filename.uptodate}">
<fileset
basedir="${ReleaseDir}">
<include
name="${string::replace(filename,path::get-full-path(ReleaseDir+'\'),'')}" />
</fileset>
</copy>
</do>
</foreach>

Subject: RE: creating a diff of two paths...
Bob,
This basic problem was causing us fits for a long time. I scoured the web for
directory difference tools that could help. There are a dozen or more tools
out there, but none really works the way you want in a source code and/or
deployment environment (believe it or not) and can be run from the command
line (e.g. from Nant).
So, I wrote my own directory differencing tool in .NET. It's a command line
program that will generate an XML file which contains a list the differences
between two directories. It filters out SVN control files. Has filters to
include any combination of SAME, MODIFIED, DELETED or ADDED files or
directories. I then use the output of this tool (via Nant <exec> task) to copy
selected differences from one location to another, and other used. The XML
output is parsed via the <xmllist> task. The XML output has markers to make
parsing easier via <xmllist>.
It is used most often to calculate the difference between two checked-out
versions of the runtime image of a deployable software component and perform
incremental updates without having to copy 1000's of files (esp. web sites).
Can also be used to identify new and or deleted files when synchronizing
directories.
It could be adapted to include and calculate file/directory dates for
differencing as well.

Subject: [NAnt-users] creating a diff of two paths...
I see that in Nant the copy command only copies newer files. What I want to be
able to do is copy files to a delta folder if they are newer rather than to the
destination folder.
So, for example given two paths, MyPath/v0 and MyPath/v1 I want to copy all the
files from MyPath/v1 that are newer than MyPath/v0 to MyPath/v1-Diff. Sort of a
combination of the uptodate and copy tasks?
The only way I can think to do it now is to loop through each file and use an
uptodate task in the loop. But, that seems like it would be quite slow.
Any ideas appreciated.
