  • Read with recursion values.
  • Read with parent-child sections.
  • Read with auto-increment key names.
  • Read with multiple-line values.
  • Read with tons of helper methods.
  • Read and convert values to Go types.
  • Read and WRITE comments of sections and keys.
  • Manipulate sections, keys and comments with ease.
  • Keep sections and keys in order as you parse and save.

Installation

The minimum requirement of Go is 1.6.
