dire

Python equivalent of Perl's warn/die functions.

Synopsis

from dire import *

warn("This will print to sys.stdout")
die("This will `warn` and then `sys.exit(1)`")
die("This will `warn` and then `sys.exit(2)`", exit_val=2)

Description

I miss having these two functions that in Perl. I find myself defining them in most every program I write, so I'm making this module so I can just import them.

warn(msg)

The warn function will simply print(message, file=sys.stderr).

die(msg, exit_val=1)

The die function will call warn with a message and will then call sys.exit with the exit_val parameter. NB: In Unix, an exit value of 0 indicates no error. The default value of die.exit_val is 1 simply because it is not zero. You could choose to set exit_val=0 to halt program execution without indicating an error.
