The package is used by the +[ogletest][ogletest] testing framework and [oglemock][oglemock] mocking +framework, which may be more directly useful to you, but can be generically used +elsewhere as well. + +A "matcher" is simply an object with a `Matches` method defining a set of golang +values matched by the matcher, and a `Description` method describing that set. +For example, here are some matchers: + +```go +// Numbers +Equals(17.13) +LessThan(19) + +// Strings +Equals("taco") +HasSubstr("burrito") +MatchesRegex("t.*o") + +// Combining matchers +AnyOf(LessThan(17), GreaterThan(19)) +``` + +There are lots more; see [here][reference] for a reference. You can also add +your own simply by implementing the `oglematchers.Matcher` interface. + + +Installation +------------ + +First, make sure you have installed Go 1.0.2 or newer. See +[here][golang-install] for instructions. + +Use the following command to install `oglematchers` and keep it up to date: + + go get -u github.com/jacobsa/oglematchers + + +Documentation +------------- + +See [here][reference] for documentation hosted on GoPkgDoc.
