# bobject-get

The get family of bobject subcommands generally operate in two modes: ref and value
4+
5+
# TODO: ensure string is ref and not just a ref of a copy of the original ref (behavior same as array/object)
6+
7+
### ref
8+
9+
In ref mode, `REPLY` is a string with the value of the global variable that contains the content you queried for.
10+
11+
### value
12+
13+
In value mode, the `REPLY` contains the actual value you want (object, array, or string).
14+
15+
Currently, only 'value' mode is implemented. PR's welcome for 'ref' mode

The set family of bobject subcommands generally operate in two modes: ref and value
4+
5+
### ref
6+
7+
In ref mode, the third argument is a string that is the name of a variable that you want to use to set
8+
9+
### value
10+
11+
In value mode, there is no "third argument". After supplying the root object and the querytree, you pass `--`, and supply your value after the double hyphen. You can supply strings, arrays, and objects
