Determine whether a byte belongs to a character set:
0x41.alpha?
# => true
Determine whether a String belongs to a character set:
"22e1c0".hex?
# => true
Return a random character from the set of all characters:
Chars.all.random_char
# => "\x94"
Return a random Array of characters from the alpha-numeric character set:
Chars.alpha_numeric.random_chars(10)
# => ["Q", "N", "S", "4", "x", "z", "3", "M", "F", "F"]
Return a random Array of a random length of unique characters from the visible character set:
Chars.visible.random_distinct_chars(1..10)
# => ["S", "l", "o", "8", "'", "q"]
Return a random String from the set of all characters:
Chars.all.random_string(10)
# => "\xc2h\xad\xccm7\x1e6J\x13"
Generate a secure password:
require 'securerandom'
Chars.visible.random_string(10..14, random: SecureRandom)
# => ".*$X=D*XK2h8gC"
Return a random String with a random length between 5 and 10, from the set of space characters:
Chars.space.random_string(5..10)
# => "\r\v\n\t\n\f"
Find all sub-strings that belong to a character set within a String:
ls = File.binread('/bin/ls')
Chars.printable.substrings(ls)
# =>
# ["/lib64/ld-linux-x86-64.so.2",
# "_ITM_deregisterTMCloneTable",
# "__gmon_start__",
# "_ITM_registerTMCloneTable",
# ...
# ]
Find all sub-strings that belong to a character set within a String, with indexes:
ls = File.binread('/bin/ls')
Chars.printable.substrings_with_indexes(ls)
# =>
# [["/lib64/ld-linux-x86-64.so.2", 792],
# ["_ITM_deregisterTMCloneTable", 4009],
# ["__gmon_start__", 4037],
# ["_ITM_registerTMCloneTable", 4052],
# ...
# ]
Enumerate over all strings from a character set of a given length:
passwords = Chars.visible.strings_of_length(6)
passwords.each { |password| puts password }
# AAAAAA
# AAAAAB
# AAAAAC
# ...
Enumerate over all strings from a character set of lengths between 4 and 8:
passwords = Chars.visible.strings_of_length(4..8)
passwords.each { |password| puts password }
# AAAA
# AAAB
# AAAC
# ...
