Moved matcher-based capture macros into their own file - this file excluded from the CATCH_CONFIG_DISABLE_MATCHERS path. - matchers are always compiled in to the impl file - _THROWS_WITH macros are still available with matchers disabled - but only the ones that take a string - tests that use matchers have #ifdefs, so the whole SelfTest project can compile with matchers disable.

#include "catch_capture.hpp"
Changed all .hpp extensions to .h where there is now a corresponding .cpp

#include "catch_matchers.h"
Add ULP and margin matcher Closes #1074
2017-11-10 18:14:42 +01:00
#include "catch_matchers_floating.h"
Add PredicateMatcher that takes an arbitrary predicate functions Also adds `Predicate` helper function to create `PredicateMatcher`. Because of limitations in type inference it needs to be explicitly typed, like so `Predicate<std::string>([](std::string const& str) { ... })`. It also takes an optional second argument for description of the predicate. It is possible to infer the argument with sufficient TMP, see https://stackoverflow.com/questions/43560492/how-to-extract-lambdas-return-type-and-variadic-parameters-pack-back-from-gener/43561563#43561563 but I don't think that the magic is worth introducing ATM. Closes #1236
