Add a :version command to GHCi
Summary
Add a :version
command to GHCi. This would show either the same as ghc --version
, or the (beginning of the) first output line of GHCi, which is e.g. "GHCi, version 9.11.20240322: https://www.haskell.org/ghc/ :? for help".
This command would especially make sense when used while GHCi is started in a quiet mode (e.g. with -v0
), where such information would not be displayed at startup.
(I guess it would also make sense in the case of a Machine accessible interface to GHCi #15461, so a controlling client could query such information.)
