I'm trying to write a custom copy task using scriptdef & ruby
but I don't find the documentation I need. The script should
(as an example) do the same as the copy task. How do I access
the original file and the mapped file ? Like in this skeleton:
<scriptdef name="mycopy" language="ruby">
???
</scriptdef>
<mycopy>
<fileset dir="." casesensitive="false">
<include name="MyFiles.*"/>
</fileset>
<mapper>
<globmapper handledirsep="true" from="MyFiles.*"
to="MyMappedFiles.*"/>
</mapper>
</mycopy>
*/
i did some quick hack and came up with =
<?xml version="1.0" encoding="UTF-8"?>
<project name="project" default="main">
<target name="depends">
<scriptdef name="mycopy" language="ruby">
<attribute name="fromdir"/>
<attribute name="includes"/>
<attribute name="destdir"/>
<attribute name="namefrom"/>
<attribute name="nameto"/>
<![CDATA[
require 'fileutils'
require 'find'
fromdir=$attributes.get("fromdir")
includes=$attributes.get("includes")
destdir=$attributes.get("destdir")
namefrom=$attributes.get("namefrom")
nameto=$attributes.get("nameto")
FileUtils.mkdir(destdir) unless File.exists?(destdir)
# you need Dir.glob ... for use of include patterns
# if you just want a recursive copy you simply use
# FileUtils.cp_r("#{fromdir}/.", "#{destdir"})
Dir.glob("#{fromdir}/#{includes}").each do |source|
file_name = File.basename(source)
target_dir = File.dirname(source).sub(/#{fromdir}/,"#{destdir}")
FileUtils.makedirs target_dir, :verbose => true
FileUtils.cp source,target_dir +'/'+ file_name,:verbose => true
end
# the rename action goes here
regexp = Regexp.new(namefrom)
Find.find(destdir) do |file|
# assuming you want to rename files only
# instead when renaming dirs also just use
# File.rename (file, ....)
unless File.directory?(file)
if file =~ /#{regexp}/
# testing with puts
# puts "File = " + file.sub(/#{regexp}/, nameto)
#the real work
File.rename(file,file.sub(/#{regexp}/, nameto))
end
end
end
]]>
</scriptdef>
</target>
<target name="main" depends="depends">
<mycopy fromdir="/home/gilreb/temp" includes="**/commons*"
destdir="/home/gilreb/temp2" namefrom="commons"
nameto="foobar"
/>
</target>
</project>
Maybe this snippet is enough to get you going.
*** i used the jruby-complete-1.1.4.jar to have all
the stuff at my fingertips, maybe the smaller jruby.jar
is enough, don't know if fileutils/find are contained ***
The recursive copy works fine, the rename actions has to be
adapted to your needs, f.e. use another regexp or when
up/downcase has to be fixed you go with
File.rename(file,file.downcase)) ... etc.
If you need more help, just let me/us know and provide
more details.
