NAME

e - beast mode 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();
'

Benchmark two snippets of code:

perl -Me -e 'n { slow => sub{ ... }, fast => sub{ ... }}, 10000'

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] }'

Print data as a table:

perl -Me -e 'table( [qw(key value)], [qw(red 111)], [qw(blue 222)] )'
+------+-------+
| key  | value |
+------+-------+
| red  | 111   |
| blue | 222   |
+------+-------+

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

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, OPTIONS )

OPTIONS:

-clone => 0,               # Will not watch cloned objects.

-methods => "fetch",       # Monitor just this method.
-methods => [ "fetch" ],   # Same.

-levels  => NUM,           # How many scope levels to show.
NUM,                       # Same.

-raw => 1,                 # Include internal calls.
-NUM,                      # Same.

-message => STR,           # Message to display.
STR,                       # Same.

prof

Profile the code from this point on.

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

n

Benchmark and compare different pieces of code.

Time single block of code.
n sub{ ... };
n sub{ ... }, 100000;

# Compare blocks of code.
n {
    slow => sub{ ... },
    fast => sub{ ... },
};
n {
    slow => sub{ ... },
    fast => sub{ ... },
}, 10000;

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.

dye

Color a string.

say dye( "HEY", "RED" );

table

Print data as a table:

perl -Me -e 'table( [qw(key value)], [qw(red 111)], [qw(blue 222)] )'
+------+-------+
| key  | value |
+------+-------+
| red  | 111   |
| blue | 222   |
+------+-------+

Context sensitive!

- Void   - output table.
- List   - return individual lines.
- Scalar - return entire table as a string.

g

Perform a get request.

l

Work with URLs.

pod

Work with perl pod.
