Golang YAML parse question

Getting Help

Hey guys,

I have the following YAML config. Here I have some repositories (repo1, repo2) and distributions (wheezy-test, centos7 etc)

repos:

  repo1:
    centos6-test:
      type:  rpm
      path:  /repo/centos/repo1/centos6-test/x86_64
    centos7:
      type: rpm
      sign: 'Secret123'
      path:  /repo/centos/repo1/centos7/x86_64

  repo2:
    wheezy-test:
      origin: EvilCorp
      label:  EvilCorp
      path:   /repo/debian/repo2/wheezy-test
      blacklist:
      - -dbg
    centos7:
      type: rpm
      sign: 'Secret123'
      path: /repo/debian/repo2/7/1.1/x86_64
      blacklist:
      - -debuginfo

I assume to parse this config I have to apply something like that:

type RepoConf struct {
    Repos Repos `yaml:"repos"`
}
type Repos struct {
    Repo1 Repo1 `yaml:"repo1"`
    Repo2 Repo2 `yaml:"repo2"`
}
type Repo1 struct {
    Centos6Test Centos6Test `yaml:"centos6-test"`
    Centos7     Centos7     `yaml:"centos7"`
}
type Repo2 struct {
    WheezyTest WheezyTest `yaml:"wheezy-test"`
    Centos7    Centos7    `yaml:"centos7"`
}
type Centos6Test struct {
    Type string `yaml:"type"`
    Path string `yaml:"path"`
}
type Centos7 struct {
    Type string `yaml:"type"`
    Sign string `yaml:"sign"`
    Path string `yaml:"path"`
}
..........

But I have too many variations of the “repoN” and distros (wheezy-test, wheezy, centos6/7/8, and so on).

Is it possible to parse this YAML config without creating a different structure for each repo and distro? Or I have to reconstruct my YAML config to have something like that:

repos:
    - repo1:
      - name: wheezy
        sign: ABC
        origin: EvilCorp
        label:  EvilCorp
        path: /somepath/bla1
        blacklist:
          - bla
      - name: wheezy-test
        sign: ABC
        origin: EvilCorp
        label:  EvilCorp
        path: /somepath/bla2
        blacklist:
          - lib

    - repo2:
      - name: centos7
        sign: '72B865FD'
        path: /somepath/bla3
        blacklist:
          - lib

I appreciate any suggestion :slight_smile:

Pasha

Can you parse into a map[string]interface{} and then translate the map to your desired internal structures?

Thank you, Jeff. I’ve used kind of suggested structure :slight_smile:
