Installs RubyGems itself. This command is ordinarily only available from a RubyGems checkout or tarball.
Specifies a Specification object that should be activated. Also contains a dependency that was used to introduce this activation.
Represents a specification retrieved via the rubygems.org API.
This is used to avoid loading the full Specification object when all we need is the name, version, and dependencies.
A GitSpecification
represents a gem that is sourced from a git repository and is being loaded through a gem dependencies file through the git:
option.
Represents a possible Specification object returned from IndexSet. Used to delay needed to download full Specification objects when only the name
and version
are needed.
An InstalledSpecification
represents a gem that is already installed locally.
A LocalSpecification
comes from a .gem file on the local filesystem.
The LockSpecification
comes from a lockfile (Gem::RequestSet::Lockfile
).
A LockSpecification’s dependency information is pre-filled from the lockfile.
The Resolver::SpecSpecification contains common functionality for Resolver specifications that are backed by a Gem::Specification
.
A Resolver::Specification contains a subset of the information contained in a Gem::Specification
. Only the information necessary for dependency resolution in the resolver is included.
A VendorSpecification
represents a gem that has been unpacked into a project and is being loaded through a gem dependencies file through the path:
option.
An object representation of a stack frame, initialized by Kernel#caller_locations
.
For example:
# caller_locations.rb def a(skip) caller_locations(skip) end def b(skip) a(skip) end def c(skip) b(skip) end c(0..2).map do |call| puts call.to_s end
Running ruby caller_locations.rb
will produce:
caller_locations.rb:2:in `a' caller_locations.rb:5:in `b' caller_locations.rb:8:in `c'
Here’s another example with a slightly different result:
# foo.rb class Foo attr_accessor :locations def initialize(skip) @locations = caller_locations(skip) end end Foo.new(0..2).locations.map do |call| puts call.to_s end
Now run ruby foo.rb
and you should see:
init.rb:4:in `initialize' init.rb:8:in `new' init.rb:8:in `<main>'
This is the JSON
generator implemented as a C extension. It can be configured to be used by setting
JSON.generator = JSON::Ext::Generator
with the method generator= in JSON
.
