Hello all! Another week, another Luau release! # Change to `lua_setuserdatametatable` This release fixes #1710: `lua_setuserdatametatable` is being changed so that it _only_ operates on the top of the stack: the `idx` parameter is being removed. Prior to this, `lua_setuserdatametable` would set the metatable of the value in the stack at `idx`, but _always_ pop the top of the stack. The old behavior is available in this release as `lua_setuserdatametatable_DEPRECATED`. # General This release exposes a generalized implementation of require-by-string's autocomplete logic. `FileResolver` can now be optionally constructed with a `RequireSuggester`, which provides an interface for converting a given module to a `RequireNode`. Consumers of this new API implement a `RequireNode` to define how modules are represented in their embedded context, and the new API manages the logic specific to require-by-string, including providing suggestions for require aliases. This enhancement moves toward integrating require-by-string's semantics into the language itself, rather than merely providing a specification for community members to implement themselves. # New Type Solver * Fixed a source of potential `Luau::follow detected a Type cycle` internal compiler exceptions when assigning a global to itself. * Fixed an issue whereby `*no-refine*` (a type which should not be visible at the end of type checking) was not being properly elided, causing inference of class-like tables to become unreadable / induce crashes in autocomplete. * Fixed a case of incomplete constraint solving when performing basic math in a loop # Fragment Autocomplete * Fixed several crashes related to not properly filling in scope information for the fragments * Fixed a source of memory corruption by isolating the return type of a fragment when it is type checked. * Improved performance by opting not to clone persistent types for the fragment (e.g.: built in types) # Internal Contributors Co-authored-by: Andy Friesen <afriesen@roblox.com> Co-authored-by: Hunter Goldstein <hgoldstein@roblox.com> Co-authored-by: Talha Pathan <tpathan@roblox.com> Co-authored-by: Varun Saini <vsaini@roblox.com> Co-authored-by: Vighnesh Vijay <vvijay@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> --------- Co-authored-by: Varun Saini <61795485+vrn-sn@users.noreply.github.com> Co-authored-by: Alexander Youngblood <ayoungblood@roblox.com> Co-authored-by: Menarul Alam <malam@roblox.com> Co-authored-by: Aviral Goel <agoel@roblox.com> Co-authored-by: Vighnesh <vvijay@roblox.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> Co-authored-by: Ariel Weiss <aaronweiss@roblox.com> |
