`juju switch` (aka `juju env`) will tell you the current environment.
 Your plugin should accept -e/--environment to override it.

I wrote a g+ post about plugins recently:

Need advice on my juju plugin

[Adam Stokes]

Writing a plugin in Go and attempting to re-create what a normal 'juju run'
would do

Here is my code:

https://github.com/battlemidget/juju-learnyouaplugin/blob/master/main.go

However, running it produces:

> juju lyaplugin --machine 1  "ls /"
  master [9d8856f]
2015-04-22 14:52:27 INFO juju.api api.go:280 connecting to API addresses:

2015-04-22 14:52:28 INFO juju.plugin.lyaplugin main.go:86 Running cmd: ls /
on machine: 1
2015-04-22 14:52:28 INFO juju.plugin.lyaplugin main.go:99 Run result: (0)
() ()

Where as `juju run --machine 1 "ls /"` shows the root level directories.

Any insight on what I'm missing is appreciated. Another note is I'm not
quite sure if there is an alternative to getting the current running
environment other than doing a `juju switch local` then running the plugin
pulling in envcmd.GetDefaultEnvironment, seen here:

https://github.com/battlemidget/juju-learnyouaplugin/blob/master/main.go#L73

This plugin is for learning purposes and I plan on writing an article for
others to write their own plugins so any best
practices/recommendations/feedback on this is welcomed!

Thanks
