Flags for string nodes.
“foo #{bar}” ^^^^^^^^^^^^
“foo #{bar}” ^^^^^^^^^^^^
Represents the use of the ‘&&=` operator for assignment to an instance variable.
@target &&= value ^^^^^^^^^^^^^^^^^
Represents the use of the ‘||=` operator for assignment to an instance variable.
@target ||= value ^^^^^^^^^^^^^^^^^
Represents assigning to an instance variable using an operator that isn’t ‘=`.
@target += value ^^^^^^^^^^^^^^^^
Helper methods for both Gem::Installer and Gem::Uninstaller
This exception is raised if the nesting of parsed data structures is too deep.
The InstructionSequence class represents a compiled sequence of instructions for the Virtual Machine used in MRI. Not all implementations of Ruby may implement this class, and for the implementations that implement it, the methods defined and behavior of the methods can change in any version.
With it, you can get a handle to the instructions that make up a method or a proc, compile strings of Ruby code down to VM instructions, and disassemble instruction sequences to strings for easy inspection. It is mostly useful if you want to learn how YARV works, but it also lets you control various settings for the Ruby iseq compiler.
You can find the source for the VM instructions in insns.def in the Ruby source.
The instruction sequence results will almost certainly change as Ruby changes, so example output in this documentation may be different from what you see.
Of course, this class is MRI specific.
Exception raised when there is an invalid encoding detected
Response class for URI Too Long responses (status code 414).
The URI provided was too long for the server to process.
References:
PrettyPrint::SingleLine is used by PrettyPrint.singleline_format
It is passed to be similar to a PrettyPrint object itself, by responding to:
but instead, the output has no line breaks
Represents writing to an instance variable in a context that doesn’t have an explicit value.
@foo, @bar = baz ^^^^ ^^^^
Represents a regular expression literal that contains interpolation that is being used in the predicate of a conditional to implicitly match against the last line read by an IO object.
if /foo #{bar} baz/ then end
^^^^^^^^^^^^^^^^
Keeps track of what elements are in the queue in priority and also ensures that when one element engulfs/covers/eats another that the larger element evicts the smaller element
AbstractSyntaxTree provides methods to parse Ruby code into abstract syntax trees. The nodes in the tree are instances of RubyVM::AbstractSyntaxTree::Node.
This module is MRI specific as it exposes implementation details of the MRI abstract syntax tree.
This module is experimental and its API is not stable, therefore it might change without notice. As examples, the order of children nodes is not guaranteed, the number of children nodes might change, there is no way to access children nodes by name, etc.
If you are looking for a stable API or an API working under multiple Ruby implementations, consider using the prism gem, which is the official Ruby API to parse Ruby code.
OpenSSL IO buffering mix-in module.
This module allows an OpenSSL::SSL::SSLSocket to behave like an IO.
You typically won’t use this module directly, you can see it implemented in OpenSSL::SSL::SSLSocket.
An Integer object represents an integer value.
You can create an Integer object explicitly with:
An integer literal.
You can convert certain objects to Integers with:
Method Integer.
An attempt to add a singleton method to an instance of this class causes an exception to be raised.
First, what’s elsewhere. Class Integer:
Inherits from class Numeric and class Object.
Includes module Comparable.
Here, class Integer provides methods for:
allbits?: Returns whether all bits in self are set.
anybits?: Returns whether any bits in self are set.
nobits?: Returns whether no bits in self are set.
<: Returns whether self is less than the given value.
<=: Returns whether self is less than or equal to the given value.
<=>: Returns a number indicating whether self is less than, equal to, or greater than the given value.
== (aliased as ===): Returns whether self is equal to the given
value.
>: Returns whether self is greater than the given value.
>=: Returns whether self is greater than or equal to the given value.
::sqrt: Returns the integer square root of the given value.
::try_convert: Returns the given value converted to an Integer.
&: Returns the bitwise AND of self and the given value.
*: Returns the product of self and the given value.
**: Returns the value of self raised to the power of the given value.
