It was developed within [Canonical](https://www.canonical.com) as -part of the [juju](https://juju.ubuntu.com) project, and is based on a -pure Go port of the well-known [libyaml](http://pyyaml.org/wiki/LibYAML) -C library to parse and generate YAML data quickly and reliably. - -Compatibility -------------- - -The yaml package supports most of YAML 1.2, but preserves some behavior -from 1.1 for backwards compatibility. - -Specifically, as of v3 of the yaml package: - - - YAML 1.1 bools (_yes/no, on/off_) are supported as long as they are being - decoded into a typed bool value. Otherwise they behave as a string. Booleans - in YAML 1.2 are _true/false_ only. - - Octals encode and decode as _0777_ per YAML 1.1, rather than _0o777_ - as specified in YAML 1.2, because most parsers still use the old format. - Octals in the _0o777_ format are supported though, so new files work. - - Does not support base-60 floats.

The Parser, on the contrary, -// is a straightforward implementation of a recursive-descendant parser (or, -// LL(1) parser, as it is usually called). -// -// Actually there are two issues of Scanning that might be called "clever", the -// rest is quite straightforward. The issues are "block collection start" and -// "simple keys". Both issues are explained below in details. -// -// Here the Scanning step is explained and implemented.
