在 YAML 中重用哈希

Question

我想在 YAML 中重用哈希：

Defaults: &defaults
  Company: Foo
  Item: 123

Computer: *defaults
  Price: 3000

但是，这会产生错误。

是单独锚定每个字段值的唯一方法吗像这样？

Defaults:
  Company: &company Foo
  Item: &item 123

Computer:
  Company: *company
  Item: *item
  Price: 3000

Answer 1

尝试通过导入来重用整个组：

Defaults: &defaults
  Company: foo
  Item: 123

Computer:
  <<: *defaults
  Price: 3000

- step:  &id001                  # defines anchor label &id001
    instrument:      Lasik 2000
    pulseEnergy:     5.4
    pulseDuration:   12
    repetition:      1000
    spotSize:        1mm

- step: &id002
    instrument:      Lasik 2000
    pulseEnergy:     5.0
    pulseDuration:   10
    repetition:      500
    spotSize:        2mm

- step: *id001                   # refers to the first step (with anchor &id001)
- step: *id002                   # refers to the second step
- step: *id001
- step: *id002
