Inspection

@look ex
@look s[, k]

Macro version of look supports a convenient way of accessing variable without relying on symbol. Both @look s.a and @look s a work the same as look(s, :a).

Examples

julia> "my system"
       @system S(Controller) begin
           "a param"
           a => 1 ~ preserve(parameter)
       end;

julia> @look S.a
[doc]
  a param

[code]
  a => 1 ~ preserve(parameter)

dive(s)

Inspect an instance of system s by navigating hierarchy of variables displayed in a tree structure.

Pressing up/down arrow keys allows navigation. Press 'enter' to dive into a deeper level and press 'q' to come back. A leaf node of the tree shows an output of look regarding the variable. Pressing 'enter' again would return a variable itself and exit to REPL.

Only works in a terminal environment; not working on Jupyter Notebook.
