Usage: ls [-m|-M|-p|-pM] [-q|-v] [-c|-i] [Object]
ls [-g] [-l]
ls shows you which methods, constants and variables are accessible to Pry. By
default it shows you the local variables defined in the current shell, and any
public methods or instance variables defined on the current object.
The colours used are configurable using Pry.config.ls.*_color, and the separator
is Pry.config.ls.separator.
Pry.config.ls.ceiling is used to hide methods defined higher up in the
inheritance chain, this is by default set to [Object, Module, Class] so that
methods defined on all Objects are omitted. The -v flag can be used to ignore
this setting and show all methods, while the -q can be used to set the ceiling
much lower and show only methods defined on the object or its direct class.
Also check out `find-method` command (run `help find-method`).
