This gem aims at being a simple and reliable solution for controlling external programs running in the background on any Ruby / OS combination.
The code originated in the selenium-webdriver gem, but should prove useful as a standalone library.
process = .build("ruby", "-e", "sleep") # inherit stdout/stderr from parent process.io.inherit! # or pass an IO process.io.stdout = Tempfile.new("child-output") process.start process.alive? #=> true process.exited? #=> false process.stop
The object returned from ChildProcess.build will implement ChildProcess::AbstractProcess.
How the process is launched and killed depends on the platform:
Unix : fork + exec
Windows : CreateProcess and friends
JRuby : java.lang.Process,ProcessBuilder
IronRuby : System.Diagnostics.Process
Note on Patches/Pull Requests
Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
