Print the value of a self.env['py'] variable.

This is useful to:
|
|
|
|
* give dry commands on the README that don't change when we refactor directory structure
|
|
* create simple bash scripts that call use self.env['py'] variables
|
|
|

For example, to get the Buildroot output directory for an ARM build, use:
|
|
|
|
....
|
|
./%(prog)s -a arm buildroot_build_dir
|
|
....
|
|
|
|
List all available variables:
|
|
|
|
....
|
|
./%(prog)s
|
|
....
|
|
''',
|
|
)
|
|
self.add_argument('variable', nargs='?')

|
|
|
def timed_main(self):
|
|
variable = self.env['variable']
|
|
if variable:
|
|
print(self.env[variable])
|
|
else:
|
|
for key in self.env:
|
|
print('{}={}'.format(key, self.env[key]))
