Returns URL-escaped string following RFC 3986.
Parses a C struct’s members
Example:
require 'fiddle/import' include Fiddle::CParser #=> Object parse_struct_signature(['int i', 'char c']) #=> [[Fiddle::TYPE_INT, Fiddle::TYPE_CHAR], ["i", "c"]] parse_struct_signature(['char buffer[80]']) #=> [[[Fiddle::TYPE_CHAR, 80]], ["buffer"]]
Reads bytes from filename and adds them to the PRNG.
Writes a number of random generated bytes (currently 1024) to filename which can be used to initialize the PRNG by calling ::load_random_file
in a later session.
offline mode. read name=value pairs on standard input.
Returns whether the HTTP
session is to be kept alive.
Yields to a block and preserves the previous set of objects being printed.
Stop tracing object allocations.
Note that if ::trace_object_allocations_start
is called n-times, then tracing will stop after calling ::trace_object_allocations_stop
n-times.
Constant time memory comparison for fixed length strings, such as results of HMAC
calculations.
Returns true
if the strings are identical, false
if they are of the same length but not identical. If the length is different, ArgumentError
is raised.
Returns a URL-encoded string derived from the given string str
.
The returned string:
Preserves:
Characters '*'
, '.'
, '-'
, and '_'
.
Character in ranges 'a'..'z'
, 'A'..'Z'
, and '0'..'9'
.
Example:
URI.encode_www_form_component('*.-_azAZ09') # => "*.-_azAZ09"
Converts:
Character ' '
to character '+'
.
Any other character to “percent notation”; the percent notation for character c is '%%%X' % c.ord
.
Example:
URI.encode_www_form_component('Here are some punctuation characters: ,;?:') # => "Here+are+some+punctuation+characters%3A+%2C%3B%3F%3A"
Encoding:
If str
has encoding Encoding::ASCII_8BIT, argument enc
is ignored.
Otherwise str
is converted first to Encoding::UTF_8 (with suitable character replacements), and then to encoding enc
.
In either case, the returned string has forced encoding Encoding::US_ASCII.
Related: URI.encode_uri_component
(encodes ' '
as '%20'
).
Returns a string decoded from the given URL-encoded string str
.
The given string is first encoded as Encoding::ASCII-8BIT (using String#b
), then decoded (as below), and finally force-encoded to the given encoding enc
.
The returned string:
Preserves:
Characters '*'
, '.'
, '-'
, and '_'
.
Character in ranges 'a'..'z'
, 'A'..'Z'
, and '0'..'9'
.
Example:
URI.decode_www_form_component('*.-_azAZ09') # => "*.-_azAZ09"
Converts:
Character '+'
to character ' '
.
Each “percent notation” to an ASCII character.
Example:
URI.decode_www_form_component('Here+are+some+punctuation+characters%3A+%2C%3B%3F%3A') # => "Here are some punctuation characters: ,;?:"
Related: URI.decode_uri_component
(preserves '+'
).
This integer returns the maximum level of data structure nesting in the generated JSON
, max_nesting
= 0 if no maximum is checked.
This sets the maximum level of data structure nesting in the generated JSON
to the integer depth, max_nesting
= 0 if no maximum should be checked.
Returns true, if circular data structures should be checked, otherwise returns false.
This method is deprecated and should not be used. This is a no-op.
