Stores the specified string value in the database, indexed via the string key provided.
Associates the value value with the specified key.
Stores a new value in the database with the given key as an index.
If the key already exists, this will update the value associated with the key.
Returns the given value.
Associates the value given by value with the key given by key.
h = { "a" => 100, "b" => 200 } h["a"] = 9 h["c"] = 4 h #=> {"a"=>9, "b"=>200, "c"=>4} h.store("d", 42) #=> 42 h #=> {"a"=>9, "b"=>200, "c"=>4, "d"=>42}
key should not have its value changed while it is in use as a key (an unfrozen String passed as a key will be duplicated and frozen).
a = "a" b = "b".freeze h = { a => 100, b => 200 } h.key(100).equal? a #=> false h.key(200).equal? b #=> true
Sets the environment variable name to value. If the value given is nil the environment variable is deleted. name must be a string.
Returns true if the named file is a directory, or a symlink that points at a directory, and false otherwise.
file_name can be an IO object.
File.directory?(".")
Returns a list of modules included/prepended in mod (including mod itself).
module Mod include Math include Comparable prepend Enumerable end Mod.ancestors #=> [Enumerable, Mod, Comparable, Math] Math.ancestors #=> [Math] Enumerable.ancestors #=> [Enumerable]
Returns true if the named file is a directory, or a symlink that points at a directory, and false otherwise.
file_name can be an IO object.
File.directory?(".")
Sends a STORE command to alter data associated with messages in the mailbox, in particular their flags. The set parameter is a number, an array of numbers, or a Range object. Each number is a message sequence number. attr is the name of a data item to store: ‘FLAGS’ will replace the message’s flag list with the provided one, ‘+FLAGS’ will add the provided flags, and ‘-FLAGS’ will remove them. flags is a list of flags.
The return value is an array of Net::IMAP::FetchData. For example:
p imap.store(6..8, "+FLAGS", [:Deleted]) #=> [#<Net::IMAP::FetchData seqno=6, attr={"FLAGS"=>[:Seen, :Deleted]}>, \\ #<Net::IMAP::FetchData seqno=7, attr={"FLAGS"=>[:Seen, :Deleted]}>, \\ #<Net::IMAP::FetchData seqno=8, attr={"FLAGS"=>[:Seen, :Deleted]}>]
Stores value in database with key as the index. value is converted to YAML before being stored.
Returns value
Quietly ensure the Gem directory dir contains all the proper subdirectories. If we can’t create a directory due to a permission problem, then we will silently continue.
If mode is given, missing directories are created with this mode.
World-writable directories will never be created.
Ruby tries to load the library named string relative to the requiring file’s path. If the file’s path cannot be determined a LoadError is raised. If a file is loaded true is returned and false otherwise.
Returns true if the contents of a stream a and b are identical.
Returns true if the contents of a stream a and b are identical.
Similar to store(), but set contains unique identifiers.
No longer raises NoMemoryError when allocating an instance of the given classes.
Quietly ensure the Gem directory dir contains all the proper subdirectories for handling default gems. If we can’t create a directory due to a permission problem, then we will silently continue.
If mode is given, missing directories are created with this mode.
World-writable directories will never be created.
Returns true if the named file is a directory, or a symlink that points at a directory, and false otherwise.
file_name can be an IO object.
File.directory?(".")
Puts the connection into binary (image) mode, issues the given server-side command (such as “STOR myfile”), and sends the contents of the file named file to the server. If the optional block is given, it also passes it the data, in chunks of blocksize characters.
Puts the connection into ASCII (text) mode, issues the given server-side command (such as “STOR myfile”), and sends the contents of the file named file to the server, one line at a time. If the optional block is given, it also passes it the lines.
