Specific parser with Ant

Hello

I use eclipse and ant for build an application (EAR). So I'd like to
generate a readme file constituted by comments of several sources code.

Ideally I'd like to put two spéchfic flags in source file and keep only
the text between those flags. I looked around FilterChain and
FilterReader ant tasks, but I can not find a way who work well.

Some idea ?
thanks

Olivier

You can write your own task. It is surprisingly easy.

You can always write some little Java program that takes command line
parms to do what you want.

Just read the source into RAM. See
http://mindprod.com/jgloss/products.html#HUNKIO

Use indexOf to find your two flags, and substring to suck up the
juice.

you can hook it up as a stand alone utility. See
http://mindprod.com/jgloss/ant.html for some examples, or you can hook
it in via the Java API to integrate it even better.

All you need is a week to read all the JavaDoc for how to do it.

thank to you and Arne for your answer

I knew the way of customized java ant task (I done it in the past), but
for this case, for the moment, I prefer use native ant task. So I
finally use a workaround with filterchain and headfilter.

You could use a combination of "find" and "sed" to accomplish this.
Maybe you do not even need "find" from an "ant" script.

Kind regards

thanks Robert

I could use those commands, but they are unix commands (isn't it ?), and
I must be windows compliant. And primarily, this readme generator is a
part of several others ant tasks

Well, there's cygwin and there's "Windows Services for Unix". :-) But
maybe you find a sed implementation in Java. Of course, writing this in
Java should not be too difficult either.

Kind regards
