Example
Here is a YAML document that exercises most of the possible ways this method can be called:
1 2 3 4 5 6 | --- - !!seq [ a ] - &pewpew - b |
The above YAML document consists of three lists, an outer list that contains two inner lists. Here is a matrix of the parameters sent to represent these lists:
1 2 3 4 | # anchor tag implicit style [ nil , nil , true , 1 ] [ nil , "tag:yaml.org,2002:seq" , false , 2 ] [ "pewpew" , nil , true , 1 ] |
