What about calling this function? GHC.Tc.Plugin.newUnique :: TcPluginM Unique The module GHC.Tc.Plugin provides facilities to plugins. More generally, here is the manual page for plugins <https://ghc.gitlab.haskell.org/ghc/doc/users_guide/extending_ghc.html#compiler-plugins>. Is it adequate? I notice that - it mentions the module GHC.Plugins (but only in code fragments) - it does not mention GHC.Tc.Plugins; neither does GHC.Plugins re-export GHC.Tc.Plugins It would be great if some plugin authors felt able to offer patches to improve. Maybe open a GHC ticket? Simon On Sat, 2 Aug 2025 at 14:16, Wolfgang Jeltsch <wolfgang@well-typed.com> wrote:

Hello!
I want to generate AST fragments in a source plugin, and for this I need to generate fresh (local) names. My current approach is to use `mkSystemName`, but it, like many of the other name-generating operations, needs a value of type `Unique`. How can I generate such values? It seems that the `Hsc` monad doesn’t carry a value of type `UniqueSupply` with it.
All the best, Wolfgang _______________________________________________ ghc-devs mailing list ghc-devs@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/ghc-devs
