how can I copy a directory of files to lower case equivalents?
Hi,
Does anyone know if there's anything in Ant that can copy files from a
directory to another directory but change all the file names to lower case?
e.g.
working/some_folder/etc/Blah.jpg => dist/some_folder/etc/blah.jpg
...
etc. for a whole load of files in various directories.
Perhaps there's something I can add to this?
<copy todir="${dist.dir}/images">
<fileset dir="images"/>
</copy>
If there's nothing in Ant directly, I'm going to have to write a PHP script
that does the renaming but I'd prefer not to create more scripts.
Any help would be much appreciated.
Many Thanks!

The ant-approved way would be a <copy> with an appropriate mapper listed
as a nested element. This gives copy the mapping from input filenames to
output names, lets it do the copying and dependency management as
normal. You just provide the renaming logic .
I dont see one, but I do see in the manual the <scriptmapper> example,
which (ant1.7+ only) would let you do what you want in a few lines
<copy todir="${dist.dir}/images">
<fileset dir="images"/>
<scriptmapper language="javascript">
self.addMappedName(source.toLowerCase());
</scriptmapper>
</copy>
If you are running on java6, javascript is built in -no need for extra
JARs to get scripting working.
Case conversion does sound like a common use case...you could always
write the java mapper and provide it with tests as an ant enhancement
bugrep.

i found an example with beanshell in the manual of ant 1.6.5.,
see my previous post.
But the problem is, with that snippet directorynames are lowercased too,
what if i want only filenames to lowercase but not the dirnames ?!
I tried to check that with your javascript mapper above, but it doesn't
run for me (ant 1.6.5)

Thanks a lot for all the suggestions. I've upgraded Ant to 1.7 as I like
this scriptmapper solution because it seems the simplest and most elegant.
I've been trying to get it working but so far no joy.
This is what I have:
...
<copy todir="${build.dir}/images/characters/icons">
<fileset dir="images/characters/icons"/>
<scriptmapper language="javascript">
self.addMappedName(source.toLowerCase());
</scriptmapper>
</copy>
...
But it currently does nothing at all. If I take out the scriptmapper task
however it goes ahead and copies the 2000+ files (obviously not to lowercase
names as I would like). My files are of the form, Archery_Aim.gif etc. and
the uppercase characters can occur anywhere - I'm not sure if this is
relevant but I thought I'd mention it.
(I'm not bothered about directory names as they are all in lowercase
anyway).

sorry forgot one line, the first post renames dirnames also,
so one has to use =
<script language="ruby">
<![CDATA[
require 'fileutils'
require 'find'
srcdir=$srcdir
destdir=$destdir
Dir.mkdir(destdir) unless File.exists?(destdir)
Dir.entries(srcdir).each do | i |
if i !='.' && i !='..'
FileUtils.cp_r Dir["#{srcdir}/**"], destdir
end
end
Find.find(destdir) do |file|
unless File.directory?(file)
File.rename(file,file.downcase)
end
end
]]>
</script>
the line =
unless File.directory?(file) prevents dirnames from
renaming

also possible with filtermapper, taken from antmanual
slightly adapted =
<!-- // Properties -->
<property name="srcdir" value="Y:/test"/>
<property name="destdir" value="Y:/test_"/>
<!-- Properties // -->
<target name="depends">
<copy todir="${destdir}">
<fileset dir="${srcdir}" includes="**/*.*"/>
<filtermapper>
<scriptfilter language="beanshell">
self.setToken(self.getToken().toLowerCase());
</scriptfilter>
</filtermapper>
</copy>
but dir's get lowercase also

Hello Alx, assuming you are on some type of NIX system (Windows doesn't car about case) the following is untested but you might want to twiddle around with it or this may get you a starting point in another direction:
<exec executable="/bin/mv">
<arg value="${file}"/>
<arg value="`echo ${file}|perl -ne 'chomp;print "$_" if (tr/A-Z/a-z/);'`"/>
</exec>
