DESCRIPTION

Mojo::Util provides portable utility functions for Mojo.

FUNCTIONS

Mojo::Util implements the following functions.

b64_decode

my $string = b64_decode $b64;

Base64 decode string.

b64_encode

my $b64 = b64_encode $string;
my $b64 = b64_encode $string, "\n";

Base64 encode string, the line ending defaults to a newline.

camelize

my $camelcase = camelize $snakecase;

Convert snake case string to camel case and replace - with ::.

# "FooBar"
camelize 'foo_bar';

# "FooBar::Baz"
camelize 'foo_bar-baz';

# "FooBar::Baz"
camelize 'FooBar::Baz';

class_to_file

my $file = class_to_file 'Foo::Bar';

Convert a class name to a file.

Foo::Bar -> foo_bar
FOO::Bar -> foobar
FooBar   -> foo_bar
FOOBar   -> foobar

class_to_path

my $path = class_to_path 'Foo::Bar';

Convert class name to path.

Foo::Bar -> Foo/Bar.pm
FooBar   -> FooBar.pm

decamelize

my $snakecase = decamelize $camelcase;

Convert camel case string to snake case and replace :: with -.

# "foo_bar"
decamelize 'FooBar';

# "foo_bar-baz"
decamelize 'FooBar::Baz';

# "foo_bar-baz"
decamelize 'foo_bar-baz';

decode

my $chars = decode 'UTF-8', $bytes;

Decode bytes to characters and return undef if decoding failed.

deprecated

deprecated 'foo is DEPRECATED in favor of bar';

encode

my $bytes = encode 'UTF-8', $chars;

Encode characters to bytes.

get_line

my $line = get_line \$string;

hmac_md5_sum

my $checksum = hmac_md5_sum $string, 'passw0rd';

Generate HMAC-MD5 checksum for string.

hmac_sha1_sum

my $checksum = hmac_sha1_sum $string, 'passw0rd';

Generate HMAC-SHA1 checksum for string.

html_unescape

my $string = html_unescape $escaped;

Unescape all HTML entities in string.

md5_bytes

my $checksum = md5_bytes $string;

Generate binary MD5 checksum for string.

md5_sum

my $checksum = md5_sum $string;

Generate MD5 checksum for string.

monkey_patch

monkey_patch $package, foo => sub {...};
monkey_patch $package, foo => sub {...}, bar => sub {...};

monkey_patch 'MyApp',
  one   => sub { say 'One!' },
  two   => sub { say 'Two!' },
  three => sub { say 'Three!' };

punycode_decode

my $string = punycode_decode $punycode;

punycode_encode

my $punycode = punycode_encode $string;

Punycode encode string.

quote

my $quoted = quote $string;

Quote string.

secure_compare

my $success = secure_compare $string1, $string2;

Constant time comparison algorithm to prevent timing attacks.

sha1_bytes

my $checksum = sha1_bytes $string;

Generate binary SHA1 checksum for string.

sha1_sum

my $checksum = sha1_sum $string;

Generate SHA1 checksum for string.

slurp

my $content = slurp '/etc/passwd';

Read all data at once from file.

spurt

$content = spurt $content, '/etc/passwd';

Write all data at once to file.

squish

my $squished = squish $string;

Trim whitespace characters from both ends of string and then change all consecutive groups of whitespace into one space each.

steady_time

my $time = steady_time;

High resolution time, resilient to time jumps if a monotonic clock is available through Time::HiRes.

trim

my $trimmed = trim $string;

Trim whitespace characters from both ends of string.

unquote

my $string = unquote $quoted;

Unquote string.

url_escape

my $escaped = url_escape $string;
my $escaped = url_escape $string, '^A-Za-z0-9\-._~';
