[ "delete specific edges in R", "I'm new to programming in R and not very good so now I've got a question about my progect. I spend a lot of time in searching a specific code about \"delete.edges\". I want to delete specific edges from my graph, those with weight 0. I have make a txt in which i have 3 columns. the first and the second are the vertices kai the third is the weight. I wrote 0 in order to define no connection, 1,2,3 etc for connection. My graph is weighted. the plot gave me all of the posible edges including those with weight=0 and now i have to delete them and make a new plot." ]

[ "Unit-testing a functional core of value objects: how to verify contracts without mocking?", "I wanted to give the Functional Core/Imperative Shell approach a shot, especially since Swift's structs are so easy to create.\n\nNow they drive me nuts in unit tests.\n\nHow do you unit test a net of value objects?\n\n\n\nMaybe I'm too stupid to search for the right terms, but in the end, the more unit tests I write, the more I think I should delete all the old ones. In other words my tests seem to bubble up the call chain as long as I don't provide mock objects. Which is impossible for (struct) value objects, because there's no way to replace them with a fake double unless I introduce a protocol, which doesn't work well in production code when methods return Self or have associated types.\n\nHere's a very simple example:\n\nstruct Foo {\n func obtainBar() -> Bar? { \n // ... \n }\n}\n\nstruct FooManager {\n let foos: [Foo]\n\n func obtainFirstBar() -> Bar {\n // try to get a `Bar` from every `Foo` in `foos`; pass the first\n // one which isn't nil down\n }\n}\n\n\nThis works well with a concrete Foo class or struct. Now how am I supposed to test what obtainFirstBar() does? -- I plug in one and two and zero Foo instances and see what happens.\n\nBut then I'm replicating my knowledge and assertions about Foo's obtainBar(). Well, either I move the few FooTests into FooManagerTests, which sounds stupid, or I use mocks to verify the incoming call instead of merely asserting a certain return value. But you can't subclass a struct, so you create a protocol:\n\nprotocol FooType {\n func obtainBar() -> Bar\n}\n\nstruct Foo: FooType { /* ... */ }\n\nclass TestFoo: FooType { /* do some mocking/stubbing */}\n\n\nWhen Bar is complex enough to warrant its own unit tests and it seems it should be mocked, you end up with this instead:\n\nprotocol FooType {\n typealias B: BarType\n\n func obtainBar() -> B\n}\n\n\nBut then the compiler will complain that FooManager's collection of foos doesn't work this way. Thanks, generics. \n\nstruct FooManager<F: FooType where F.B == Bar> {\n let foos: [F] // ^^^^^^^^^^^^^^^^ added for clarity \n\n func obtainFirstBar() -> Bar { /* ... */ }\n}\n\n\nYou can't pass in different kinds of Foo, though. Only one concrete FooType is allowed, no weird mixes of BlueFoo and RedFoo, even if both return the same Bar and seem to realize the FooType protocol in the same way. This isn't Objective-C and duck typing isn't possible. Protocols don't seem to add much benefit in terms of abstraction here anyway unless they're not depending on anything else which is a protocol or Self.\n\nIf protocols lead to confusion and not much benefit at all, I'd rather stop using them. But how do I write unit tests if one object is mostly a convoluted net of dependent objects, all being value types, seldomly optional, without moving all tests for every permutation in the test suite of the root object(s)?" ]
