样本file.yml
:
---
- foo: bar
bing:
- bong
- bang
people:
- { name: pin, nicknames: ['pin', 'first'] }
- { name: deb, nicknames: ['deb'] }
- { name: roger, nicknames: ['roger'] }
- { name: kenny, nicknames: ['kenny'] }
- { name: annie, nicknames: ['annie'] }
我尝试使用yq对people
对象按name
排序,除了pin
,它应该放在第一位。
所需输出:
---
- foo: bar
bing:
- bong
- bang
people:
- { name: pin, nicknames: ['pin', 'first'] }
- { name: annie, nicknames: ['annie'] }
- { name: deb, nicknames: ['deb'] }
- { name: kenny, nicknames: ['kenny'] }
- { name: roger, nicknames: ['roger'] }
❯ yq -V
yq (https://github.com/mikefarah/yq/) version v4.31.2
我已经做了切片和排序,但这只会打印排序后的切片:
❯ yq '.[].people.[1:] | sort_by(.name)' file.yml
- {name: annie, nicknames: ['annie']}
- {name: deb, nicknames: ['deb']}
- {name: kenny, nicknames: ['kenny']}
- {name: roger, nicknames: ['roger']}
不知道怎么把剩下的放回去,或者我是否在正确的轨道上。

实际上,只将
|
更改为|=
,以便在保留原始上下文的情况下对数组切片执行update操作,就可以完成这项工作(对于kislyuk/yq确实如此)。然而,对于mikefarah/yq,由于某种原因,数组返回时没有排序:所以,你可以手动地把第一个元素切掉,然后把它重新添加到独立排序的数组切片中:
