NAME

Carp::Source - Warn of errors with stack backtrace and source context

VERSION

version 1.101420

SYNOPSIS

    use Carp::Source 'source_cluck';
    source_cluck 'some error';
    source_cluck 'some error',
        lines => 5, number => 0, color => 'yellow on_blue';

DESCRIPTION

This module exports one function, source_cluck(), which prints stack traces with source code extracts to make it obvious what has been called from where.

It does not work for one-liners because there is no file from which to load source code.

FUNCTIONS

source_cluck

    source_cluck 'some error';
    source_cluck 'some error',
        lines => 5, number => 0, color => 'yellow on_blue';

Like Carp's cluck(), but it also displays the source code context of all call frames, with three lines before and after each call being shown, and the call being highlighted.

It takes as arguments a string (the error message) and a hash of options. The following options are recognized:

lines

Number of lines to display before and after the line reported in the stack trace. Defaults to 3.

number

Boolean value to indicate whether line numbers should be printed at the beginning of the context source code lines. Defaults to yes.

color

The color in which to print the source code line reported in the stack trace. It has to be a string that Term::ANSIColor understands. Defaults to black on_yellow.

This is just a quick hack - not all of Carp's or even just cluck()'s features are present. The code borrows heavily from Carp.
