According to https://en.wikipedia.org/wiki/YAML#Repeated_nodes you can do the following in YAML
- 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 spotSize: 2mm # redefines just this key, refers rest from &id001 - step: *id002
Although when you try to override spotSize key of step with reference *id001 you get
yaml.parser.ParserError: while parsing a block mapping in "C:\Users\...\test.yaml", line 1, column 1 expected <block end>, but found '<block mapping start>' in "C:\Users\...\test.yaml", line 29, column 5
Could somebody give a hint on how to implement that and would that be merged if I did that?
