bastienleonard / hutte Goto Github PK

Continued from issue #1:

now to figure out how to get the output of "run" commands into variables for processing.
thanks.

Update: scratch all that, use the object that is now returned by local() and run(): https://bastienleonard.github.io/hutte/reference/command_result.html

There isn't a public API for that, but I'll try to add it soon.
In the mean time, if you really need to capture the output of a command, you can use the internal API.
This will be a bit more complicated than necessary because the internal API uses callbacks, so that the output of long-running commands in shown in real time.

For remote commands (self is a Dsl instance, if the block you passed to SshSession.run() takes a parameter, then pass it instead):

Hutte::ssh_exec(self.instance_variable_get('@session'), 'pwd') do |callback|
  callback.on_stdout do |data|
    puts data
  end.on_stderr do |data|
    puts data
  end.on_exit_status_received do |status|
    puts "Exit status: #{status}"
  end
end

For local commands:

status = Hutte::LocalShell.run('pwd') do |callback|
  callback.on_stdout do |data|
    puts data
  end.on_stderr do |data|
    puts data
  end
end

puts "Exit status: #{status}"

Note that you're on your own here, for example Hutte won't raise an error if the command fails (status != 0). Also error checking is minimal, your app will crash if a callback that wasn't supplied gets called.

Can hutte be made to use ~/.ssh/config so can specify name that is a "Host" in .ssh/config and it will use the full hostname, port, identityfile etc?
