Fun kata! I'm always impressed at the clever things you can do with decorators.
I don't know how, but I've lost a revision with a lot of additional tests. In this published revision, test sets 2 and 3 don't even list the arguments yet and aren't used anywhere. I'll close this issue when I restore my work
Done
hi!
can you please give a hint how to solve this kata? I don't understand how to implement the syntax, as an example: "is_even & is_positive"
I have already studied the topic of predicates and bitwise operations
Hi. You need to look up "operator overloading" and "magic methods"
ty :D
I've studied the topics you've given me, but I can't figure out how a function, a class, and just a variable with the same name should be combined with themselves. Can you please suggest the structure of the solution?
I'm not sure what you mean by "combined with themselves". Can you provide a code example?
Hi,
the
Test random logical expressionsdeclaration needs to be adescribeblock, not aitone (since it's not a "leaf test block")Cheers
actually, you should get rid of that block and the
test_compound_predicatesfunction and just run the loop isnide the "random tests" describe blocktest_compound_predicatesis actually necessary and it's called three times with different arguments, but that revision got lost somehow. After I fix that, I'll return to your issue and eliminate that non-leafitDone
oh, yeah. I didn't read the full test suite (just saw that this block was in red in the output panel)
While the
& | ~interface is the same, I beleive that it's not a duplicate.Readable Specification Patternfocuses on class hacks, and this kata focuses on flexible interface not limited to 1 argument
