esilva-everbridge / yaml

Wraps goyaml functions for easier use of YAML files as configuration sources.

gosexy/yaml

This package is a wrapper of goyaml.

gosexy/yaml provides friendly methods for loading, reading and writing to and from YAML formatted files.

Useful if you just want to read/write setting files in your Go programs.

Installation

go get menteslibres.net/gosexy/yaml

Usage

After installing, use the following import path.

import "menteslibres.net/gosexy/yaml"

Here's an example that creates a YAML file and writes some values on it:

package main

import (
	"menteslibres.net/gosexy/yaml"
)

func main() {
	settings := yaml.New()

	settings.Set("success", true)
	settings.Set("nested", "tree", 1)
	settings.Set("another", "nested", "tree", []int{1, 2, 3})

	settings.Write("test.yaml")
}

The above code generates a test.yaml file like this:

another:
  nested:
    tree:
    - 1
    - 2
    - 3
nested:
  tree: 1
success: true

A detail of another example:

settings, err := yaml.Open("examples/input/settings.yaml")

if err != nil {
	log.Printf("Could not open YAML file: %s", err.Error())
}

s := to.String(settings.Get("test_string"))

fmt.Printf("%s", s)

If the referred settings.yaml contains a line like this:

test_string: "Hello World!"

The the output would be:

Hello World!

Note that you can use nested paths on Set() and Get():

/*
path:
	to:
		nested:
			value: 1
*/
settings.Set("path", "to", "nested", "value", 1)

// yaml.*Yaml.Get() returns interface{}.
i := settings.Get("path", "to", "nested", "value")

fmt.Printf("%d\n", i)
// Prints: 1

You can also use gosexy/to to convert from interface{} into a compatible type:

// to.Int64() returns int64.
i := to.Int64(settings.Get("path", "to", "nested", "value"))

fmt.Printf("%d\n", i)
// Prints: 1
