// 将 input 语句按第一个管道符拆分，获取两个子句
const { indexstr, statement } = splitQuery(input) 

// 解析 promql 语句，返回语句包含的指标集
const metricRes = findMetrics(input)
metricRes.forEach((m) => {
  console.log('metricName: ', m.name)
  console.log('metricLabelList: ', m.labels)
})

// 解析 promql 语句，返回在 listRange 范围内的所有聚合算子
const listRange = ['avg', 'max']
const aggRes = findAggregations(input, listRange)

// 操作 promql 语句， 返回新的 promql 语句
// modifiers, see type MetricModifierList
const newStr = operateLabelForPromql(input, modifiers)

// 获取 group by 节点， 返回节点（字符串）集
const res = getGroupBy(input)

// 设置 group by 节点，返回操作完后的语句
const res = setGroupBy(input, groupByList)
