Myrddin

A powerful yaml template engine for golang.

Usage

Import

import "github.com/taubyte/myrddin"

Define a struct that will receive the data. Example:

type MyConfig struct {
	Hostname string `yaml:"host"`
	Shell    string `yaml:"shell"`
	Name     string `yaml:"name"`
	Networks []struct {
		Name      string `yaml:"name"`
		AddrRange struct {
			Start string `yaml:"start"`
			End   string `yaml:"end"`
		} `yaml:"addr_range"`
	} `yaml:"networks"`
}

Create a myrddin instance and pass the recipient struct as an argument

config := &MyConfig{}
m, err := myrddin.New(config)

You can aslo pass custom data and function as options

m, err := myrddin.New(
    config,
    myrddin.Data(
        "ver",
        []string{"v0.0.1"},
    ),
    myrddin.Function(
        "unixTime",
        func() { return time.Now().Unix() },
    ),
)

Then, load the folder containing your files

err = m.Load("config")

Finally, parse:

err = m.Parse()

Example

cd example
go run .

Output should look like

host: hostname
shell: /bin/bash
name: test
networks:
    - name: net0
      addr_range:
        start: 192.168.0.1
        end: 192.178.0.100
    - name: net1
      addr_range:
        start: 192.168.1.1
        end: 192.178.1.100
    - name: net2
      addr_range:
        start: 192.168.2.1
        end: 192.178.2.100
