Various utils

Patching standard classes: Hash, Array, String, Nil, Numeric, Object and Thread.

This gem is supported thanks to pro.ruby community ( https://t.me/pro_rb ).

Hash

present? == empty?

keys_to_symbols
# Transform keys *recursive* String => Symbol

deep_merge( Hash )

keys?( *list )
# All keys from list must be present

any_key?( *list )
# At least one key from list must be present

filter_keys( *list )

recursive_transorm_values( &block )
# do not processes more than one level on arrays

hash.key.otherkey.more notation, also hash.key? returns true/false, also hash.key1.key2 = value works, even if key2 not exists.

Also here's simple id generator based on current time AMQProto#correlation_id.

Object

present? != nil

String

like_number?
# regexp determining is that Float or Numeric

present? != empty?

from_json
# JSON with rescue to {}

from_yaml
# YAML with rescue to {}

from_msgpack
# MsgPack with rescue to {}

from_zlib
# Zlib with rescue to {}

from_xml

raises exception if XML header contain :schemaLocation, xs:schema, xmlns:xs uses nori for parsing

to_a
# => [self]

snakecase()

camelcase()

percent_encode()

Stupid encoding without any parsing as described in Twitter OAuth doc

Array

include?(*list)
# must include all elements from list

include_one?( *list )
# must include at least one item from list

symbolize_hashes
# Additional for Hash#keys_to_symbols

AMQProto

correlation_id() # => String

Numeric

present? # == always true

to_a # [ self ]

Thread

wait_for_key( k, tmout )
# Waith for thread-local variable returning `false` after timeout and `true` before timeout
# So, if variable was set, this function will return true

Nil

empty? == true

present? == false

dig(*args) == self

to_a == []

call(*args) == self

Proc

_dump_data == to_s
