Hi all!
I’m another Ruby noob and wondered if any of you can help me with my
problem.
I’ve have been tasked with writing some rake files to automate parts of
our project and to begin I’m trying to automate the setup of the build
machine. The first task is to set the environment variables.
Can this be done in Ruby without using system("%PATH% =
%PATH%;c:\ruby\bin") etc.?
Thanks in advance!!! ( :

will be vaild only in processes that you’ll start from your script, in
other words, you cannot modify parent environment. (you could do by
some batch file wizardry)

ENV cannot be assigned too.
Sorry

The environment CAN be assigned to. What you can’t do is propagate it
upwards. Any processes you spawn from your Ruby application will use
your new environment table, but you can’t call a Ruby application to
set your environment in its parent.

This is very nice got my test upwards down, hmmm, ENV is not a hash but
reponds to the same methods as a Hash, thus element assignment.
Sorry for the noise.
