Question

I want to copy some files with Rake, but compared to Ant this is kind of clumsy and my implementation is a bit stupid.

The source files have read only flags, I wish to copy files with write access (ant did this automatically).
If the target is not newer than the source, then I don’t want to copy.

Here is my current code:

source = c:\perforce\read\only\lame
target = c:\deploy\files\stop\writing\read\only
FileList[source].each do |src|
  cp source, src.sub(source, target), :verbose => true
  chmod 0644, src.sub(source,target)
end

Ant would be

<copy todir="target" verbose="true">
  <fileset dir="source">
    <include name="*" />
  </fileset>
</copy>

I would use a bit different approach:

FileUtils.cp_r File.join(source,'*'), target
FileUtils.chmod_R target

But You were asking for:

if (FileUtils.uptodate?(src,trgt)) cp src,trgt,:verbose=>true
