Temporarily change current directory in Rake

Question

I would like to run multiple commands need to be (or is easier to be) in another directory, then once they're done, return back to the previous working directory.

I'm envisioning something similar to Fabric's with cd(path):, e.g.:

cd('.git') do
   File.unlink('config')
end

Is there an inbuilt way of doing this in Rake, or should I be writing a custom method that accepts a block, etc.?

Answer 1

It is simply the inbuilt Dir#chdir call:

Dir.chdir('.git') do
  File.unlink('config')
end

Excerpt from the docs:

If a block is given, it is passed the name of the new current directory, and the block is executed with that as the current directory. The original working directory is restored when the block exits.
