# NAME

e - beastmode unleashed

# SYNOPSIS

Add a trace marker:

    perl -Me -e 'sub f1 { trace } sub f2 { f1 } f2'

Watch a reference for changes:

    perl -Me -e 'my $v = {}; sub f1 { watch( $v ) } sub f2 { f1; $v->{a} = 1 } f2'

    perl -Me -e '
        package A {
            use e;
            my %h = ( aaa => 111 );

            watch(\%h);

            sub f1 {
                $h{b} = 1;
            }

            sub f2 {
                f1();
                delete $h{aaa};
            }
        }

        A::f2();
    '

Launch the Runtime::Debugger:

    perl -Me -e 'repl'

Invoke the Tiny::Prof:

    perl -Me -e 'prof'

Convert a data structure to json:

    perl -Me -e 'say j { a => [ 1..3] }'

Convert a data structure to yaml:

    perl -Me -e 'say yml { a => [ 1..3] }'

Pretty print a data structure:

    perl -Me -e 'p { a => [ 1..3] }'

Data dump a data structure:

    perl -Me -e 'd { a => [ 1..3] }'

Devel::Peek dump a data structure:

    perl -Me -e 'dd { a => [ 1..3] }'

# DESCRIPTION

This module imports many features that make
one-liners and script debugging much faster.

It has been optimized for performance to not
import all features right away:
thereby making its startup cost quite low.

# SUBROUTINES

## monkey\_patch

Insert subroutines into the symbol table.

Extracted from Mojo::Util for performance.

Perhaps can be updated based on the outcome
of this issue:
[https://github.com/mojolicious/mojo/pull/2173](https://github.com/mojolicious/mojo/pull/2173)

## import

## repl

Add a breakpoint to code.

Basically inserts a Read Evaluate Print Loop.

Enable to analyze code in the process.

## trace

Show a stack trace.

    trace( $depth=1 )

## watch

Watch a reference for changes.

    watch( $ref, $depth=3 )

## prof

Profile the code from this point on.

    my $obj = prof;
    ...
    # $obj goes out of scope and builds results.

## j

JSON Parser.

## x

XML parser.

## yml

YAML parser.

## b

Work with strings.

## c

Work with arrays.

## f

Work with files.

## say

Print with newline.

## p

Pretty data printer.

## np

Return pretty printer data.

## d

Data dumper.

## dd

Internal data dumper.

## g

Perform a get request.

## l

Work with URLs.

## pod

Work with perl pod.
