The goyaml package enables [[http://golang.org|Go]] programs to very comfortably encode and decode YAML values. It was developed within Canonical as part of an experiment related to using the Go language with the [[https://juju.ubuntu.com|juju]] project. goyaml internally uses the C [[http://pyyaml.org/wiki/LibYAML|libyaml]] library to parse and generate YAML data fast and reliably. It ships with all the necessary files, though, and has no external dependencies besides Go itself. == Compatibility == goyaml is almost compatible with YAML 1.1, including support for anchors, tags, etc. There are still a few missing bits, such as document merging, base-60 floats (WTF), and multi-document unmarshalling. These features are not hard to add, and will be introduced as necessary. == API documentation == The API documentation is currently available at: http://goneat.org/pkg/launchpad.net/goyaml == Example == Here is a simple example which connects to !ZooKeeper, waits for the session to be established, and attempts to create a node: {{{ package main import ( "launchpad.net/goyaml" "fmt" ) var data = ` a: Easy! b: c: 2 d: [3, 4] ` type T struct { A string B struct{C int; D []int ",flow"} } func main() { t := T{} err := goyaml.Unmarshal([]byte(data), &t) if err != nil { panic(err) } fmt.Printf("--- t:\n%v\n\n", t) d, err := goyaml.Marshal(&t) if err != nil { panic(err) } fmt.Printf("--- t dump:\n%s\n\n", string(d)) m := make(map[interface{}]interface{}) err = goyaml.Unmarshal([]byte(data), &m) if err != nil { panic(err) } fmt.Printf("--- m:\n%v\n\n", m) d, err = goyaml.Marshal(&m) if err != nil { panic(err) } fmt.Printf("--- m dump:\n%s\n\n", string(d)) } }}} This example will generate the following output: {{{ --- t: {Easy! {2 [3 4]}} --- t dump: a: Easy! b: c: 2 d: [3, 4] --- m: map[a:Easy! b:map[c:2 d:[3 4]]] --- m dump: a: Easy! b: c: 2 d: - 3 - 4 }}} == Source code == To obtain the source code, use [[http://bazaar.canonical.com|Bazaar]] to download it from Launchpad: {{{ $ bzr branch lp:goyaml }}} == Reporting bugs == Please report bugs at: https://launchpad.net/goyaml == How to build and install goyaml == To make use of goyaml, just run the following command: {{{ $ goinstall launchpad.net/goyaml }}} == Running tests == To run tests, first install [[http://labix.org/gocheck|gocheck]] with: {{{ $ goinstall launchpad.net/gocheck }}} Then run gotest as usual: {{{ $ gotest }}} == License == goyaml is licensed under the LGPL. == Contact == This project is being developed under the [[https://launchpad.net/ensemble|Ensemble]] project at [[http://www.canonical.com|Canonical]]. To get in touch, send a message to the Ensemble mailing list at: <ensemble@lists.ubuntu.com> |
