Usage: cat FILE
|
|
cat --ex [STACK_INDEX]
|
|
cat --in [INPUT_INDEX_OR_RANGE]
|
|
|
|
`cat` is capable of showing part or all of a source file, the context of the
|
|
last exception, or an expression from Pry's input history.
|
|
|
|
`cat --ex` defaults to showing the lines surrounding the location of the last
|
|
exception. Invoking it more than once travels up the exception's backtrace, and
|
|
providing a number shows the context of the given index of the backtrace.
