Release v0.28.0 · ruby/prism

Added

Nested hashes will now warn for duplicated keys, as in: { foo: 1, **{ foo: 2 } }.
Prism::ReturnNode now has a flag on it to indicate if it is redundant.
Prism::Location#slice_lines and Prism::Node#slice_lines are now provided to slice the source code of a node including the content before the node on the same line that it starts on and the content after the node on the same line that it ends on.
Symbols with invalid byte sequences now give errors.
You can now pass "3.3.1" to the version: parameter on all Prism.* APIs.
Prism::Source#lines, Prism::Location#source_lines, Prism::Node#source_lines, and Prism::Node#script_lines are now provided, which will all return the source code of the source as an array of strings.
Prism::ASCIISource is now provided, which is a subclass of Prism::Source but specialized to increase performance when the source is entirely ASCII.
Prism now provides errors when parsing Ruby 3.4+ syntax for index expressions with keywords or blocks.
Prism now provides an error when **nil is used after other keyword parameters.
Prism now provides errors when safe navigation is used in call target expressions, e.g., foo&.bar, = 1.
Prism::Node#tunnel is now provided, which returns an array of nodes starting at the current node that contain a given line and column.

All translation layers now assume an eval context, which means they will not return errors for invalid jumps like yield.
Prism::Node#inspect now uses a queue instead of recursion to avoid stack overflows.
Prism now more closely mirrors CRuby interpolation semantics, which means you could potentially have a static literal string that directly interpolates another static literal string.
The shipped RBI sorbet types no longer use generics.
Prism::ConstantPathNode#child and Prism::ConstantTargetNode#child are now deprecated, replaced by two new fields on these nodes: name and name_loc.
