Re: [nant-dev] New task: cat
There is already a concat task in NAntContrib...

Re: [nant-dev] New task: cat
Sascha, I guess I have this question... Should both these functionalities be combined in a single task?

Re: [nant-dev] New task: cat
I agree. Filter should probably be a seperate task. It might be worth looking at Ants filterset concept. http://ant.apache.org/manual/CoreTypes/filterset.html Ian Sascha, I guess I have this question...

[nant-dev] New task: cat
Hi,
I had a problem where I merge sourcefiles into one assembly,
while I use them normally in more than one assembly to link
only what I need.
I'm using the ndoc task to document, and hence it's missing
the namespace descriptions, if I do not create a new
namespace.xml for the merged assembly.
Basicly appending all namespace.xml files from the seperated
assemblies into one new would do the job. I would do this
with cat under unix, but I found it nice to have a task
doing this.
There are three attributes:
* file
* pipe
* append
The last two are optional. The first one is the file to cat.
If this is the only attribute given, it will print it on the
screen. If pip is given, it will create - that means
overwrite, since append defaults to false - the given file
and insert the contents of file. If append is true the
content is appended where I've reached what I wanted.
I just think I post it here for inclusion in NAnt or
NAnt-contrib.
