Settings framework for framework or library.
Your framework or library might need default settings and you want your user to change them.
Many developer wrote this kind of code, and you are going to. GluePlate is it!
You and your user write easiry.
Just import Glue as _ and write like nested dict.
from glueplate import Glue as _ settings = _( GLUE_PLATE_ENVIRONMENT_VARIABLE_KEY = 'BASEPACKAGE_SETTINGS_MODULE', from_base = 'comming from base', to_be_override = 'I am base.', )
glueplate import variable named
settings from os.environ[‘GLUE_PLATE_BASE_MODULE’], this is a base settings.
Then glueplate looks settings.GLUE_PLATE_ENVIRONMENT_VARIABLE_KEY and import variable named
settings from os.environ[settings.GLUE_PLATE_ENVIRONMENT_VARIABLE_KEY], this is a user customized settings. Customized settings needs only user needs override, or addition.
from glueplate import Glue as _ settings = _( from_sub='comming from sub', to_be_override = 'I am sub.', )
They are merged and easy to use.
from glueplate import config assert('I am sub' == config.settings.to_be_override) assert('comming from base' == config.settings.from_base) assert('comming from sub' == config.settings.from_sub)
You may not want to override by you user, just add user’s additional data.
glueplate provide special keyword prefix to append original settings variable.
User can append list before.# base settings = _( list1 = [1,2,3], ) # user customized settings = _( GLUE_PLATE_PLUS_BEFORE_list1 = [5,4] ) # config.settings.list1 == [5, 4, 1, 2, 3]
Same as GLUE_PLATE_PLUS_BEFORE_ but append to backward.# base settings = _( list1 = [1,2,3], ) # user customized settings = _( GLUE_PLATE_PLUS_AFTER_list1 = [5,4] ) # config.settings.list1 == [1, 2, 3, 5, 4]
You might use library using glueplate. Environment variable
GLUE_PLATE_BASE_MODULE is only one on your process.
Your base settings can indecate library’s gluplate settings module.
Specify library’s gluplate settings module names as list.from glueplate import Glue as _ settings = _( GLUE_PLATE_PARENT_MODULES=[ 'parentpackage1.parentpackage1_settings', 'parentpackage2.parentpackage2_settings' ] )
