YAML Ain’t Markup Language

学以致用,最近要做Go单测,需要学习了解一下Golang。其实很早就有学的愿望。学不以致用,就没下文了。十年纪念中文版链接站点看到这一篇YAML入门:以创建一个Kubernetes deployment为例。对比一下这两个等价描述,优势就一目了然了。

kind: Pod
  name: rss-site
    app: web

    - name: rss-reader

  • YAML is a human friendly data serialization standard for all programming languages.
  • 2001年5月12号发布第一版本,最早的讨论在Yahoo Group,现在已经连接失效了
  • 创世人包括Oren Ben-Kiki,Clark Evans和Ingy döt Net
  • 名字来源类似GNU的定义,YAML Ain’t Markup Language
  • 官方推荐使用.yaml结尾命名文件,目前大家似乎更多使用.yml
  • 因为tab键的实现不同,yaml采用空格方式进行描述
  • 官方网站about保留了更多信息
  • YAML正式文档目前是第三版,final YAML 1.2
  • 几乎所有主流语言都有对应的实现支持

YAML™ is an international collaboration to make a data serialization language which is both human readable and computationally powerful. The founding members of YAML are Ingy döt Net (author of the Perl module Data::Denter), Clark Evans, and Oren Ben-Kiki. YAML emerged from the union of two efforts. The first was Ingy döt Net’s need for a serialization format for Inline, this resulted in his Data::Denter module. The second, was the joint work of Oren Ben-Kiki Clark Evans on simplifying XML within the sml-dev group. YAML was first publicized with a  article on 12 May 2001. Oren and Clark’s vision for YAML was very similar to Ingy’s Data::Denter, and vice versa, thus a few days later they teamed up and YAML was born.
