libstdgo

Standard libraries for Go, taking care of things like:

• concurrent: concurrent and thread-safe data structures —
  • AtomicCounter: atomic int64 counter
  • Scoreboard: a space-efficient map of string-keyed int64 counters
  • AtomicReference an atomic reference that allows for nil pointers
  • Deadline - conditional running of tasks that are bound to a deadline
• scribe: logging façade that features logger mocking and assertions, and comes with ready-to-go bindings for —
  • The built-in os.Stdout file handle
  • The built-in log package
  • Glog
  • Log15
  • Logrus
  • Seelog
  • Zap
  • Overlog — a thread-safe logger for debugging concurrent apps, built into Scribe
• check: assertion utilities
  • ThatPanicsAsExpected(func): asserting panic expectations
  • Wait(t, timeout).UntilAsserted(assertion): time-based assertions
  • TestCapture: capture of testing.T failures (for self-testing of assertion libraries)
  • Intercept(t).Mutate(...): enrichment of assertion failure messages
• commander: schemaless command-line argument parsing
  • Parse(os.Args).Mappify
• fault: fault injection
• arity: extraction of optional arguments to variadic functions
  • arg := arity.SoleUntyped("a_default", args).(string)
• diags: debugging and diagnostics
