Important: Chilkat's ULID functionality was introduced in v9.5.0.94.

Ruby

require 'chilkat'

dt = Chilkat::CkDateTime.new()

# A ULID must be exactly 26 chars in length,
# and is composed of the following chars: 0123456789ABCDEFGHJKMNPQRSTVWXYZ
# Note: The ULID alphabet excludes the letters I, L, O, and U

# Here's a valid ULID
ulid = "01GRGCH4J88RECEN4D4VK4F629"
valid = dt.UlidValidate(ulid)
print "valid: " + valid.to_s() + "\n";

# Here's an invalid ULID
ulid = "71GRGxx4Jr8RECEN4D4VK4F62!"
valid = dt.UlidValidate(ulid)
print "valid: " + valid.to_s() + "\n";
