It provides an API similar to [encoding/json][json] and [encoding/xml][xml]. [fmt]: https://brandur.org/logfmt [json]: https://pkg.go.dev/encoding/json [xml]: https://pkg.go.dev/encoding/xml The logfmt format was first documented by Brandur Leach in [this article][origin]. The format has not been formally standardized. The most authoritative public specification to date has been the documentation of a Go Language [package][parser] written by Blake Mizerany and Keith Rarick. [origin]: https://brandur.org/logfmt [parser]: https://pkg.go.dev/github.com/kr/logfmt ## Goals This project attempts to conform as closely as possible to the prior art, while also removing ambiguity where necessary to provide well behaved encoder and decoder implementations. ## Non-goals This project does not attempt to formally standardize the logfmt format. In the event that logfmt is standardized this project would take conforming to the standard as a goal. ## Versioning This project publishes releases according to the Go language guidelines for [developing and publishing modules][pub].
