Here is a snippet beanshell that can do the work for you:
<scriptdef
name = "sortFiles"
language = "beanshell" >
<classpath>
<!-- Set up here to include you libs, ie beanshell and friends
-->
<!--
This is where I store mine :)
<fileset dir = "${keros.dependency.HOME}" includes =
"*.jar"/>
-->
</classpath>
<attribute name = "dir"/>
<![CDATA[
java.io.File dir = new java.io.File ( attributes.get (
"dir" ) );
String[] files = dir.list ();
int maxLen = 0;
for ( String file : files )
{
if ( file.length () > maxLen )
{
maxLen = file.length ();
}
}
StringBuilder sb = new StringBuilder ();
for ( int len = 0; len < maxLen; len++ )
{
sb.append ( ' ' );
}
String padding = sb.toString ();
java.util.TreeSet treeSet = new java.util.TreeSet ();
for ( String file : files )
{
if ( file.length () < maxLen )
{
treeSet.add ( padding.substring ( 0, maxLen -
file.length () ) + file );
}
else
{
treeSet.add ( file );
}
}
for ( String entry : treeSet )
{
System.out.println ( entry.trim () );
}
]]>
</scriptdef>
I tested and it definitely works :)
To run, I did this:
<sortFiles dir = "/home/sfloess/testdir"/>
The directory /home/sfloess/testdir contains the files:
10.sql 11.sql 1.sql 2.sql
The results when run:
[sortFiles] 1.sql
[sortFiles] 2.sql
[sortFiles] 10.sql
[sortFiles] 11.sql
HTH,

Well, there is the <script> task which can help you make this happen. It's
an optional Ant task, and you need to include in a few additional jarfiles
when you run Ant. <

macro can be found here: <
http://ant.apache.org/manual/OptionalTasks/script.html>.
I've never used the script macro, so I can't help you there, but you are
taking on a rather complex task.
You need to collect the file names, create a "sortkey" for each file name,
sort the files on that key, and then recall these names one-by-one. There is
no "numeric sort" command I know of in most languages, so you'll have to do
that yourself. You'll need to do that in an "approved" language which may
not be a language you are familiar with.
If you are a decent Java developer, you could try writing a custom Ant task.
Information about that can be found in the Ant Manual here: <
http://ant.apache.org/manual/tutorial-writing-tasks.html>.
Lots of luck with your endeavor.

Yes it way to solve, but i don't want fill zero in first filename, if i
write new task i don't know where i had started :(
Anyone can suggest? Please advice me.
Thx.

Well, it is sorting the files by name. Unfortunately, it is sorting them
in
ASCII dictionary order.
The easiest way (and maybe the only way) is to zero fill in the names of
these files when you create them, so that you have 001.sql and 010.sql
instead of 1.sql and 10.sql.
That way, they'll sort in the order you want:
001.sql
002.sql
010.sql
011.sql
I looked at Resource Collections, and there is a <sort> resource
collection,
but nothing to customize your sort order the way you want.
You could write your own task or script, but it's probably not worth it.

Hi all,
I have use foreach task from ant-contrib, the output like this

10.sql
11.sql
2.sql
And, i want to sort file name like this:
1.sql
2.sql
10.sql
11.sql

This is my code :

<foreach param="file" target="loop">
<path>

</fileset>
</path>
</foreach>
</target>
<target name="loop"> <echo>${file}</echo>
</target>
</project>
-------------------------------------------------------------------------------
What should do to solve this problem?
Thanks & Regards,
