This module allows you to see detailed and pretty formatted stack straces of perl functions call. It exports a single function - bt. In void context, it sends it's output to STDERR. In scalar context, it returns you collected data as string.



This string is appended to each line of output. Defaults to ' ' (two spaces).


How many symbols of a string eval to print. Defaults to 40.


How many call frames to go up. Defaults to 0 (unlimited).


How many calls up of the current frame to start printing. Defaults to 0 (do not skip anything).


Functions in a packages that are hash keys of %IgnorePkg are not shown in the stack trace output.


Options for Data::Printer, that determine how to render arguments. If you need special formatting, do it here.
