Overview

Essential utilities missing from the Go standard library.

Docs: https://pkg.go.dev/github.com/mitranim/gg

Some features:

  • Designed for Go 1.18. Takes massive advantage of generics.
  • Errors with stack traces.
  • Checked math.
  • Various functional programming utilities: map, filter, fold, and more.
  • Various shortcuts for reflection.
  • Various shortcuts for manipulating slices.
  • Various shortcuts for manipulating maps.
  • Various shortcuts for manipulating strings.
  • Common-sense generic data types: zero optionals, true optionals, sets, indexed collections, and more.
  • Various utilities for exception-style error handling, using panic and recover.
  • CLI flag parsing.
  • Various utilities for testing.
    • Assertion shortcuts with descriptive errors and full stack traces.
  • Carefully designed for compatibility with standard interfaces and interfaces commonly supported by 3rd parties.
  • No over-modularization.
  • No external dependencies.

Submodules:

  • gtest: testing and assertion tools.
  • grepr: tools for printing Go data structures as Go code.
  • gsql: SQL tools:
    • Support for scanning SQL rows into Go structs.
    • Support for SQL arrays.

Current limitations:

  • Not fully documented.
