yaml-translator

Decode YAML documents, valiate them, and translate validation errors back to yaml doc line numbers.

For example, this struct definition:

type Config struct {
	Version  int32    `yaml:"version" validate:"eq=1"`
	WordList []string `yaml:"word_list" validate:"dive,alpha"`
}

would, when parsed against this yaml:

version: 2
word_list:
 - Fo2o
 - Bar

produces validation errors like:

yaml validation failed with 2 errors:
  - version (<input>:1:9) is not equal to 1
  - Field word_list[0] (<input>:3:3): validation failed on the 'alpha' tag
