Hannes Siebenhandl pushed to branch wip/fendor/no-load at Glasgow Haskell Compiler / GHC Commits: 5ce67b3d by fendor at 2025-06-24T16:37:08+02:00 Implement `-fno-load-initial-targets` flag We add the new flag `-fno-load-initial-targets` which doesn't load all `Target`s immediately but only computes the module graph for all `Target`s. The user can then decide to load modules from that module graph using the syntax: ghci> :reload <Mod> This will load everything in the module graph up to `Mod`. The user can return to the initial state by using the builtin target `none` to unload all modules. ghci> :reload none Is in principle identical to starting a new session with the `-fno-load-initial-targets` flag. The `-fno-load-initial-targets` flag allows for faster startup time of GHCi when a user has lots of `Target`s. We additionally extend the `:reload` command to accept multiple `ModuleName`s. For example: ghci> :reload <Mod1> <Mod2> Loads all modules up to the modules `Mod1` and `Mod2`. - - - - - 35 changed files: - compiler/GHC/Driver/DynFlags.hs - compiler/GHC/Driver/Flags.hs - compiler/GHC/Driver/Make.hs - compiler/GHC/Driver/Session.hs - compiler/GHC/Unit/Module/Graph.hs - docs/users_guide/ghci.rst - ghc/GHCi/UI.hs - ghc/GHCi/UI/Exception.hs - + testsuite/tests/ghci/prog-mhu005/Makefile - + testsuite/tests/ghci/prog-mhu005/a/A.hs - + testsuite/tests/ghci/prog-mhu005/all.T - + testsuite/tests/ghci/prog-mhu005/b/B.hs - + testsuite/tests/ghci/prog-mhu005/prog-mhu005a.script - + testsuite/tests/ghci/prog-mhu005/prog-mhu005a.stderr - + testsuite/tests/ghci/prog-mhu005/prog-mhu005a.stdout - + testsuite/tests/ghci/prog-mhu005/unitA - + testsuite/tests/ghci/prog-mhu005/unitB - + testsuite/tests/ghci/prog021/all.T - − testsuite/tests/ghci/prog021/prog021.T - testsuite/tests/ghci/prog021/prog021.script → testsuite/tests/ghci/prog021/prog021a.script - testsuite/tests/ghci/prog021/prog021.stderr → testsuite/tests/ghci/prog021/prog021a.stderr - testsuite/tests/ghci/prog021/prog021.stdout → testsuite/tests/ghci/prog021/prog021a.stdout - + testsuite/tests/ghci/prog021/prog021b.script - + testsuite/tests/ghci/prog021/prog021b.stderr - + testsuite/tests/ghci/prog021/prog021b.stdout - + testsuite/tests/ghci/prog022/A.hs - + testsuite/tests/ghci/prog022/B.hs - + testsuite/tests/ghci/prog022/Makefile - + testsuite/tests/ghci/prog022/all.T - + testsuite/tests/ghci/prog022/ghci.prog022a.script - + testsuite/tests/ghci/prog022/ghci.prog022a.stderr - + testsuite/tests/ghci/prog022/ghci.prog022a.stdout - + testsuite/tests/ghci/prog022/ghci.prog022b.script - + testsuite/tests/ghci/prog022/ghci.prog022b.stderr - + testsuite/tests/ghci/prog022/ghci.prog022b.stdout The diff was not included because it is too large.
