The SourceSet chooses the best available method to query a remote index.

Kind off like BestSet but filters the sources for gems

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.

Gem::Security default exception type

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

An absolutely silent IO.

Common implementation for SVCB-compatible resource records.

The parser gem has a list of diagnostics with a hard-coded set of error messages. We create our own diagnostic class in order to set our own error messages.

Generic SvcParam abstract class.

A generic resource abstract class.

Removes and returns elements from self.

With numeric argument index given, removes and returns the element at offset index:

a = ['a', 'b', 'c', 'd']
a.slice!(2)   # => "c"
a             # => ["a", "b", "d"]
a.slice!(2.1) # => "d"
a             # => ["a", "b"]

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

a = ['a', 'b', 'c', 'd']
a.slice!(-2) # => "c"
a            # => ["a", "b", "d"]

If index is out of range, returns nil.

With numeric arguments start and length given, removes length elements from self beginning at zero-based offset start; returns the removed objects in a new array:

a = ['a', 'b', 'c', 'd']
a.slice!(1, 2)     # => ["b", "c"]
a                  # => ["a", "d"]
a.slice!(0.1, 1.1) # => ["a"]
a                  # => ["d"]

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

a = ['a', 'b', 'c', 'd']
a.slice!(-2, 1) # => ["c"]
a               # => ["a", "b", "d"]

If start is out-of-range, returns nil:

a = ['a', 'b', 'c', 'd']
a.slice!(5, 1)  # => nil
a.slice!(-5, 1) # => nil

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

a = ['a', 'b', 'c', 'd']
a.slice!(2, 50) # => ["c", "d"]
a               # => ["a", "b"]

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

If length is negative, returns nil.

With Range argument range given, treats range.min as start (as above) and range.size as length (as above):

a = ['a', 'b', 'c', 'd']
a.slice!(1..2) # => ["b", "c"]
a              # => ["a", "d"]

If range.start == a.size, returns a new empty array:

a = ['a', 'b', 'c', 'd']
a.slice!(4..5) # => []

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

a = ['a', 'b', 'c', 'd']
a.slice!(5..6) # => nil

If range.start is negative, calculates the start index by counting backwards from the end of self:

a = ['a', 'b', 'c', 'd']
a.slice!(-2..2) # => ["c"]

If range.end is negative, calculates the end index by counting backwards from the end of self:

a = ['a', 'b', 'c', 'd']
a.slice!(0..-2) # => ["a", "b", "c"]

Removes and returns the substring of self specified by the arguments. See String Slices.

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>

Replaces some or all of the content of self with str, and returns self. The portion of the string affected is determined using the same criteria as String#byteslice, except that length cannot be omitted. If the replacement string is not the same length as the text it is replacing, the string will be adjusted accordingly.

If str_index and str_length, or str_range are given, the content of self is replaced by str.byteslice(str_index, str_length) or str.byteslice(str_range); however the substring of str is not allocated as a new string.

The form that take an Integer will raise an IndexError if the value is out of range; the Range form will raise a RangeError. If the beginning or ending offset does not land on character (codepoint) boundary, an IndexError will be raised.
