jsonnet: 又一种配置文件

一个不错的配置文件格式

安装

brew install go-jsonnet

示例

{
  array: [1, 2] + [3],
  math: (4 + 5) / 3 * 2,
  format: 'Hello, I am %s' % 'alei',
  concat: 'Hello, ' + 'I am alei',
  slice: [1,2,3,4][1:3],
  'list comprehension': [x * x for x in [1,2,3,4]],
  condition:
    if 2 > 1 then
    'true'
    else
    'false',
}

编译出的结果

$ jsonnet test.jsonnet

      2,
      3
