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

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.

encode

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

Encode characters to bytes.

get_line

  my $line = get_line \$string;

Extract whole line from string or return undef. Lines are expected to end with 0x0d 0x0a or 0x0a.

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_escape

  my $escaped = html_escape $string;
  my $escaped = html_escape $string, '^\n\r\t !#$%(-;=?-~';

Escape unsafe characters in string with HTML5 entities, the pattern used defaults to ^\n\r\t !#$%(-;=?-~.

html_unescape

  my $string = html_unescape $escaped;

Unescape all HTML5 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.

punycode_decode

  my $string = punycode_decode $punycode;

Punycode decode string.

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.

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\-._~';

Percent-encode unsafe characters in string, the pattern used defaults to ^A-Za-z0-9\-._~.

url_unescape

  my $string = url_unescape $escaped;

Decode percent-encoded characters in string.

xml_escape

  my $escaped = xml_escape $string;

Escape only the characters &, <, >, " and ' in string, this is a much faster version of html_escape.
