Vladislav Zavialov pushed to branch wip/int-index/imp-exp-whole-namespace at Glasgow Haskell Compiler / GHC Commits: 55eab80d by Sylvain Henry at 2025-11-20T17:33:13-05:00 Build external interpreter program on demand (#24731) This patch teaches GHC how to build the external interpreter program when it is missing. As long as we have the `ghci` library, doing this is trivial so most of this patch is refactoring for doing it sanely. - - - - - 08bbc028 by Rodrigo Mesquita at 2025-11-20T17:33:54-05:00 Add tests for #23973 and #26565 These were fixed by 4af4f0f070f83f948e49ad5d7835fd91b8d3f0e6 in !10417 - - - - - 6b42232c by sheaf at 2025-11-20T17:34:35-05:00 Mark T26410_ffi as fragile on Windows As seen in #26595, this test intermittently fails on Windows. This commit marks it as fragile, until we get around to fixing it. - - - - - b7b7c049 by Andrew Lelechenko at 2025-11-21T21:04:01+00:00 Add nubOrd / nubOrdBy to Data.List and Data.List.NonEmpty As per https://github.com/haskell/core-libraries-committee/issues/336 - - - - - 352d5462 by Marc Scholten at 2025-11-22T10:33:03-05:00 Fix haddock test runner to handle UTF-8 output xhtml 3000.4.0.0 now produces UTF-8 output instead of escaping non-ASCII characters. When using --test-accept it previously wrote files in the wrong encoding because they have not been decoded properly when reading the files. - - - - - 3e714d6e by Vladislav Zavialov at 2025-11-26T14:29:40+03:00 Namespace-specified wildcards in import/export lists (#25901) This change adds support for top-level namespace-specified wildcards `type ..` and `data ..` to import and export lists. Examples: import M (type ..) -- imports all type and class constructors from M import M (data ..) -- imports all data constructors and terms from M module M (type .., f) where -- exports all type and class constructors defined in M, -- plus the function 'f' The primary intended usage of this feature is in combination with module aliases, allowing namespace disambiguation: import Data.Proxy as T (type ..) -- T.Proxy is unambiguously the type constructor import Data.Proxy as D (data ..) -- D.Proxy is unambiguously the data constructor The patch accounts for the interactions of wildcards with: * Imports with `hiding` clauses * Import warnings -Wunused-imports, -Wdodgy-imports * Export warnings -Wduplicate-exports, -Wdodgy-exports Summary of the changes: 1. Move the NamespaceSpecifier type from GHC.Hs.Binds to GHC.Hs.Basic, making it possible to use it in more places in the AST. 2. Extend the AST (type: IE) with a representation of `..`, `type ..`, and `data ..` (constructor: IEWholeNamespace). Per the proposal, the plain `..` is always rejected with a dedicated error message. 3. Extend the grammar in Parser.y with productions for `..`, `type ..`, and `data ..` in both import and export lists. 4. Implement wildcard imports by updating the `filterImports` function in GHC.Rename.Names; the logic for IEWholeNamespace is roughly modeled after the Nothing (no explicit import list) case. 5. Implement wildcard exports by updating the `exports_from_avail` function in GHC.Tc.Gen.Export; the logic for IEWholeNamespace is closely modeled after the IEModuleContents case. 6. Refactor and extend diagnostics to report the new warnings and errors. See PsErrPlainWildcardImport, DodgyImportsWildcard, PsErrPlainWildcardExport, DodgyExportsWildcard, TcRnDupeWildcardExport. Note that this patch is specifically about top-level import/export items. Subordinate import/export items are left unchanged. - - - - - 119 changed files: - compiler/GHC.hs - + compiler/GHC/Driver/Config/Interpreter.hs - compiler/GHC/Driver/Config/Linker.hs - compiler/GHC/Driver/DynFlags.hs -
