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.

Gem::Security default exception type

A source representing a single .gem file. This is used for installation of local gems.

An absolutely silent IO.

Gem::Resolver::Molinillo is a generic dependency resolution algorithm.

A generic resource abstract class.

Error raised when no cdylib artifact was created

Converts Ruby link flags into something cargo understands

IO wrapper that provides only write

A state that encapsulates a single possibility to fulfill the given {#requirement}

Provides information about specifications and dependencies to the resolver, allowing the {Resolver} class to remain generic while still providing power and flexibility.

This module contains the methods that users of Gem::Resolver::Molinillo must to implement, using knowledge of their own model classes.

Delegates all {Gem::Resolver::Molinillo::SpecificationProvider} methods to a ‘#specification_provider` property.

Removes and returns elements from self.

When the only argument is an Integer n, removes and returns the nth element in self:

a = [:foo, 'bar', 2]
a.slice!(1) # => "bar"
a # => [:foo, 2]

If n is negative, counts backwards from the end of self:

a = [:foo, 'bar', 2]
a.slice!(-1) # => 2
a # => [:foo, "bar"]

If n is out of range, returns nil.

When the only arguments are Integers start and length, removes length elements from self beginning at offset start; returns the deleted objects in a new Array:

a = [:foo, 'bar', 2]
a.slice!(0, 2) # => [:foo, "bar"]
a # => [2]

If start + length exceeds the array size, removes and returns all elements from offset start to the end:

a = [:foo, 'bar', 2]
a.slice!(1, 50) # => ["bar", 2]
a # => [:foo]

If start == a.size and length is non-negative, returns a new empty Array.

If length is negative, returns nil.

When the only argument is a Range object range, treats range.min as start above and range.size as length above:

a = [:foo, 'bar', 2]
 a.slice!(1..2) # => ["bar", 2]
a # => [:foo]

If range.start == a.size, returns a new empty Array.

If range.start is larger than the array size, returns nil.

If range.end is negative, counts backwards from the end of the array:

a = [:foo, 'bar', 2]
a.slice!(0..-2) # => [:foo, "bar"]
a # => [2]

If range.start is negative, calculates the start index backwards from the end of the array:

a = [:foo, 'bar', 2]
a.slice!(-2..2) # => ["bar", 2]
a # => [:foo]

Removes the substring of self specified by the arguments; returns the removed substring.

See String#[] for details about the arguments that specify the substring.

A few examples:

string = "This is a string"
string.slice!(2)        #=> "i"
string.slice!(3..6)     #=> " is "
string.slice!(/s.*t/)   #=> "sa st"
string.slice!("r")      #=> "r"
string                  #=> "Thing"

Returns a substring of self, or nil if the substring cannot be constructed.

With integer arguments index and length given, returns the substring beginning at the given index of the given length (if possible), or nil if length is negative or index falls outside of self:

s = '0123456789' # => "0123456789"
s.byteslice(2)   # => "2"
s.byteslice(200) # => nil
s.byteslice(4, 3)  # => "456"
s.byteslice(4, 30) # => "456789"
s.byteslice(4, -1) # => nil
s.byteslice(40, 2) # => nil

In either case above, counts backwards from the end of self if index is negative:

s = '0123456789'   # => "0123456789"
s.byteslice(-4)    # => "6"
s.byteslice(-4, 3) # => "678"

With Range argument range given, returns byteslice(range.begin, range.size):

s = '0123456789'    # => "0123456789"
s.byteslice(4..6)   # => "456"
s.byteslice(-6..-4) # => "456"
s.byteslice(5..2)   # => "" # range.size is zero.
s.byteslice(40..42) # => nil

In all cases, a returned string has the same encoding as self:

s.encoding              # => #<Encoding:UTF-8>
s.byteslice(4).encoding # => #<Encoding:UTF-8>

The license for this gem.

The license must be no more than 64 characters.

This should just be the name of your license. The full text of the license should be inside of the gem (at the top level) when you build it.

The simplest way is to specify the standard SPDX ID spdx.org/licenses/ for the license. Ideally, you should pick one that is OSI (Open Source Initiative) opensource.org/licenses/alphabetical approved.

The most commonly used OSI-approved licenses are MIT and Apache-2.0. GitHub also provides a license picker at choosealicense.com/.

You can also use a custom license file along with your gemspec and specify a LicenseRef-<idstring>, where idstring is the name of the file containing the license text.

You should specify a license for your gem so that people know how they are permitted to use it and any restrictions you’re placing on it. Not specifying a license means all rights are reserved; others have no right to use the code for any purpose.

You can set multiple licenses with licenses=

Usage:

spec.license = 'MIT'
