pyconfigvar 1.0.0

Manage required and optional environment variables in your scripts.

# pyconfigvar

Manage required and optional environment variables in your Python scripts.

## Example

`sh $ REQUIRED_VAR="something" python `

`python >>> import pyconfigvar >>> pyconfigvar.requiredvar('REQUIRED_VAR') 'something' >>> pyconfigvar.requiredvar('MISSING_VAR') >>> pyconfigvar.requiredvar('MISSING_VAR') MISSING_VAR was not supplied in the environment. <drop back to shell> `

## Usage

There are four functions available:

### requiredvar(var)

Returns the contents of the environment variable var. If var is not present in the environment, sys.exit() is invoked to terminate the interpreter.

### optionalvar(var, default)

Like requiredvar(), but instead of terminating, default is returned.

### requiredbool(var)

Like requiredvar(), but will coerce the value of var into a boolean and return that. Essentially, anything non-zero or non-empty will return True, otherwise it will return False.

### optionalbool(var, default)

Like requiredbool(), but will return default rather than terminate the interpreter.
