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 '+').
SecHandle struct
Creates binary representations of a SecBufferDesc structure, including the SecBuffer contained inside.
Enumerator::ArithmeticSequence is a subclass of Enumerator, that is a representation of sequences of numbers with common difference. Instances of this class can be generated by the Range#step and Numeric#step methods.
The class can be used for slicing Array (see Array#slice) or custom collections.
An FFI closure wrapper, for handling callbacks.
closure = Class.new(Fiddle::Closure) { def call 10 end }.new(Fiddle::TYPE_INT, []) #=> #<#<Class:0x0000000150d308>:0x0000000150d240> func = Fiddle::Function.new(closure, [], Fiddle::TYPE_INT) #=> #<Fiddle::Function:0x00000001516e58> func.call #=> 10
FIXME: This isn’t documented in Nutshell.
Since MonitorMixin.new_cond returns a ConditionVariable, and the example above calls while_wait and signal, this class should be documented.
UDP/IP address information used by Socket.udp_server_loop.
Zlib::GzipWriter is a class for writing gzipped files. GzipWriter should be used with an instance of IO, or IO-like, object.
Following two example generate the same result.
Zlib::GzipWriter.open('hoge.gz') do |gz| gz.write 'jugemu jugemu gokou no surikire...' end File.open('hoge.gz', 'w') do |f| gz = Zlib::GzipWriter.new(f) gz.write 'jugemu jugemu gokou no surikire...' gz.close end
To make like gzip(1) does, run following:
orig = 'hoge.txt' Zlib::GzipWriter.open('hoge.gz') do |gz| gz.mtime = File.mtime(orig) gz.orig_name = orig gz.write IO.binread(orig) end
NOTE: Due to the limitation of Ruby’s finalizer, you must explicitly close GzipWriter objects by Zlib::GzipWriter#close etc. Otherwise, GzipWriter will be not able to write the gzip footer and will generate a broken gzip file.
exception to wait for writing by EAGAIN. see IO.select.
exception to wait for writing by EWOULDBLOCK. see IO.select.
exception to wait for writing by EINPROGRESS. see IO.select.
Note: Don’t use this class directly. This is an internal class.
Timer id conversion keeps objects alive for a certain amount of time after their last access. The default time period is 600 seconds and can be changed upon initialization.
To use TimerIdConv:
DRb.install_id_conv TimerIdConv.new 60 # one minute
A custom InputMethod class used by XMP for evaluating string io.
HTTPGenericRequest is the parent of the Net::HTTPRequest class.
Do not use this directly; instead, use a subclass of Net::HTTPRequest.
Response class for Non-Authoritative Information responses (status code 203).
The Non-Authoritative Information response indicates that the server is a transforming proxy (such as a Web accelerator) that received a 200 OK response from its origin, and is returning a modified version of the origin’s response.
References:
Response class for Found responses (status code 302).
The Found response indicates that the client should look at (browse to) another URL.
References:
Response class for Unauthorized responses (status code 401).
Authentication is required, but either was not provided or failed.
