Notebook

Functions to use py2gift from a Jupyter notebook.

Convenience functions

A class to act as a container. This will be useful to simulate a Python module.

ClassesContainer

 ClassesContainer ()

Initialize self. See help(type(self)) for accurate signature.

classes_container = ClassesContainer()

class DummyClass:
    
    n = 3

classes_container.add(DummyClass)

classes_container.DummyClass

__main__.DummyClass

classes_container.DummyClass.n

Magics

source

MyMagics

 MyMagics (shell=None, **kwargs)

*Base class for implementing magic functions.

Shell functions which can be reached as %function_name. All magic functions should accept a string, which they can parse for their own needs. This can make some functions easier to type, eg %cd ../ vs. %cd("../")

Classes providing magic functions need to subclass this class, and they MUST:

Use the method decorators @line_magic and @cell_magic to decorate individual methods as magic functions, AND
Use the class decorator @magics_class to ensure that the magic methods are properly registered at the instance level upon instance initialization.

See :mod:magic_functions for examples of actual implementation classes.*

Parser

The class can be instantiated directly,

m = MyMagics()

to test the parser,

m.location_parser.parse_args('settings -c myclass -C mycategory'.split())

Namespace(settings='settings', cls='myclass', category=['mycategory'])

When no category nor class are passed:

m.location_parser.parse_args('settings'.split())

Namespace(settings='settings', cls=None, category=None)

Parsed category is always a list

m.location_parser.parse_args('settings -c myc -C cat 1'.split())

Namespace(settings='settings', cls='myc', category=['cat', '1'])

json should be used to pass the category. Then, within the magic, the category list is joined (with a space) and parsed back using json to whatever type it originally had.

category = 'foo'
line = m.location_parser.parse_args(f'settings -c myc -C {json.dumps(category)}'.split())
json.loads(' '.join(line.category))

'foo'

category = 'foo foo'
line = m.location_parser.parse_args(f'settings -c myc -C {json.dumps(category)}'.split())
json.loads(' '.join(line.category))

'foo foo'

category = ['cat', 'subcat']
line = m.location_parser.parse_args(f'settings -c myc -C {json.dumps(category)}'.split())
json.loads(' '.join(line.category))

['cat', 'subcat']

Notice that a json-dumped string is not equal to the string,

json.dumps('Category 1') == 'Category 1'

False

meaning that, if in a variable, the category must always be dumped

Actual use

Magics must be somehow registered

# %lmagic -n foo

settings = py2gift.input_file.Settings()
category_name = settings.add_category('Category 1')
settings.add_or_update_class(category_name=category_name, class_name='question name', question_base_name='base name', n_instances=2)

settings.to_dict()

{'output file': 'quiz.yaml',
 'pictures base directory': 'quiz/pics',
 'categories': [{'name': 'Category 1',
   'classes': [{'name': 'question name',
     'question base name': 'base name',
     'number of instances': 2}]}]}
