allow legacy SCTs to specify copy option

v2.6.1

Create setup.py

option to disable copying in has_expr

pythonwhat tries make deepcopies of some objects, to avoid problems arising from mutation via SCTs.
Now the copy arg can disable deep copying. Should speed up SCTs, but can be scary and dangerous.

E.g. Ex().has_equal_value(copy = False)

bugfix: remove unnecessary root Expr in has_equal_ast

v2.5.1

bump patch version

has_equal_ast enhancements

• now has code and exact arguments for specifying code for solution ast, and whether to test that AST is exact match or only contained in submission.

has_context SCT

Also remove exclamatory failure messages!

add override SCT

• check_function(..., signature = True) is now the default (as intended)
• override function

e.g.

Ex().override("if True: print(1)").check_if_else(0).has_equal_ast()

Add check_function, has_equal_ast

May now test sum([1,2,3]), using

Ex().check_function('sum', 0).check_args(0).has_equal_ast()

Fix logic issue

v2.1.2

bump version

Fix dilling issue

Fix issue with dilling

Post-refactor release

• Documentation through testthedocs. Several high-level articles to grasp pythonwhat's new structure.
• Formatted messages, if you start your messages with FMT:
• Highlighting for test_function() is disabled for now, because gives unwanted behavior in several use-cases. Stays like this until elegant solution is found that works nicely by default in all situations. Highlighting can be controlled through the highlight argument.
• All check_ functions use zero-based indexing. test_for_loop(1), but check_for_loop(0).
• test_not operator to negate operations, exciting!
