#15145: Emit info-level log message when package environments have been picked up -------------------------------------+------------------------------------- Reporter: hvr | Owner: (none) Type: feature | Status: new request | Priority: high | Milestone: 8.4.3 Component: Compiler | Version: 8.0.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- A common complaint with the new package environment files feature is that it's not obvious when package environments have be picked up. Even though this feature has been in GHC since GHC 8.0, now with cabal 2.2 turning on ghc env file generation, this getting wider exposure. A similiar UI issue existed with GHCi and its `.ghci` files and the solution there was to emit a message informing the user that an implicit configuration file was picked up: {{{ GHCi, version 8.5.20180512: http://www.haskell.org/ghc/ :? for help Loaded GHCi configuration from /home/hvr/.ghci Prelude> }}} The same solution would greatly reduce the confusion with package environment files which have an even trickier lookup logic than `.ghci` files. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15145 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
