Enables chunked transfer encoding.
Return value associated with key.
If there is no value for key and no block is given, returns ifnone.
Otherwise, calls block passing in the given key.
See ::DBM#fetch for more information.
Returns the number of the signal that caused stat to stop (or nil if self is not stopped).
Similar to read, but raises EOFError at end of string instead of returning nil, as well as IO#sysread does.
Executes the block for every line in the stream where lines are separated by eol.

Reads a one-character string from the stream. Raises an EOFError at end of file.
Generate a Checkbox Input element as a string.
The attributes of the element can be specified as three arguments, name, value, and checked. checked is a boolean value; if true, the CHECKED attribute will be included in the element.
Alternatively, the attributes can be specified as a hash.
checkbox("name") # = checkbox("NAME" => "name") checkbox("name", "value") # = checkbox("NAME" => "name", "VALUE" => "value") checkbox("name", "value", true) # = checkbox("NAME" => "name", "VALUE" => "value", "CHECKED" => true)
Returns the header field corresponding to the case-insensitive key. Returns the default value args, or the result of the block, or raises an IndexError if there’s no header field named key See Hash#fetch
Returns “true” if the “transfer-encoding” header is present and set to “chunked”. This is an HTTP/1.1 feature, allowing the the content to be sent in “chunks” without at the outset stating the entire content length.
returns a charset parameter in Content-Type field. It is downcased for canonicalization.
If charset parameter is not given but a block is given, the block is called and its result is returned. It can be used to guess charset.
If charset parameter and block is not given, nil is returned except text type in HTTP. In that case, “iso-8859-1” is returned as defined by RFC2616 3.7.1.
Switch the effective and real user IDs of the current process. If a block is given, the user IDs will be switched back after the block is executed. Returns the new effective user ID if called without a block, and the return value of the block if one is given.
Switch the effective and real group IDs of the current process. If a block is given, the group IDs will be switched back after the block is executed. Returns the new effective group ID if called without a block, and the return value of the block if one is given.
Same as Array#each, but passes the index of the element instead of the element itself.
An Enumerator is returned if no block is given.
a = [ "a", "b", "c" ] a.each_index {|x| print x, " -- " }
produces:
0 -- 1 -- 2 --
Same as Array#each, but traverses self in reverse order.
a = [ "a", "b", "c" ] a.reverse_each {|x| print x, " " }
produces:
c b a
By using binary search, finds an index of a value from this array which meets the given condition in O(log n) where n is the size of the array.
It supports two modes, depending on the nature of the block and they are exactly the same as in the case of bsearch method with the only difference being that this method returns the index of the element instead of the element itself. For more details consult the documentation for bsearch.
