New page

I needed to take a patch file, which contained patches from more than one Eclipse project, and create a zip file with each file contained within.

The Eclipse patch file basically looks like:

<geshi lang="patch">
### Eclipse Workspace Patch 1.0
#P My Little Project

System.out.println("Hello customer");

</geshi>

You have a project definition, followed by files in that project. You can have multiple project definitions. I created a Ruby script to parse the file and keep track of the project name. The script then outputs the qualified path to each file it encounters. Sure, I could have done this with awk, but Ruby is more enjoyable and readable.

<geshi lang="ruby">
#!/bin/env ruby

ARGV.each do |arg|
if !File.exists?(arg) then
raise(RuntimeError,"#{arg} does not exist!")
end
File.open(arg, 'r') do |infile|
while(line = infile.gets)
if line =~ /^#P ([^\r]*)/ then # ignore any new line characters
project = $1
end
if line =~ /^Index: ([^\r]*)/ then
puts '"' + project + '/' + $1 + '"'
end
end
end
end
</geshi>

Lastly, to zip up these files, I used bash/Cygwin.

<geshi lang="bash">
./patchToFiles.rb patches/mypatch.patch | xargs zip mypatch.zip
</geshi>
