tips

• vmap decode data with spf13/viper. Note that viper automatically lower case all the keys it found in input.

considering enhancements

• Support XML output
• Support CSV output
• Decode non-UTF8 charsets

packages that power vmap

• BurntSushi/toml
• spf13/cobra
• spf13/viper
• k0kubun/pp
• go-yaml/yaml
