YAML Multi-Line Arrays

Question

In YAML  you can easily create multi-line strings  However  I would like the ability to create a multi-line array  mainly for readibility within config files  using the   character   A YAML array can be represented as    key1    key2    key3     A YAML sequence uses a dash followed by a space and then a string   - String1 - String2 - String3   This would evaluate to    string1    string2    string3     A YAML mapping is an array of key and value pairs that we see all the time in YAML   Key1  string1 Key2  string2 Key3  string3   This is all well and good  but I can t for the life of me see how to do a multi-line array  Something like this       string1    string2    string3     string4    string5    string6     Short of creating multiple array mappings in YAML and merging them in my programming language of choice  is there any way to achieve multi-line arrays  maybe with     like Python has but in YAML

If what you are needing is an array of arrays  you can do this way   key    -    value11    value12    value13      -    value21    value22    value23

A YAML sequence is an array  So this is the right way to express it   key    - string1   - string2         - string3   - string4   - string5   - string6   That s identical in meaning to   key    string1    string2    string3    string4    string5    string6     It s also legal to split a single-line array over several lines   key    string1    string2    string3       string4    string5       string6     and even have multi-line strings in single-line arrays   key    string1    long   string    string3    string4    string5    string6

The following would work   myarray      String1  String2  String3    String4  String5  String5  String7     I tested it using the snakeyaml implementation  I am not sure about other implementations though
