engine.SCons.Variables.BoolVariable

This file defines the option type for SCons implementing true/false values.

...
if env['embedded'] == 1:
...

Functions

[hide private]

BoolVariable(key, help, default)
The input parameters describe a boolean option, thus they are returned with the correct converter and validator appended. The 'help' text will by appended by '(yes|no) to show the valid valued. The result is usable for input to opts.Add().

source code

_text2bool(val)
Converts strings to True/False depending on the 'truth' expressed by the string. If the string can't be converted, the original value will be returned.

source code

_validator(key, val, env)
Validates the given value to be either '0' or '1'.
