Other than that, `--show-options` is documented in user manual. But this brought my attention to another issue with the help message. We are mentioning `-fglasgow-exts` flag in the help message, but that flag actually is deprecated and generates a warning. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8190#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

On the other hand, most other compilers (eg clang and gcc) do have a way of listing all of the documented options, or at least most of them. however, Theres definitely value in having a curated list of all the stable flags when someone does {{{ ghc -h or ghc --help }}} which we currently only do i the barest minimal sense possible -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8190#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

It would also make it much easier to find options that are not documented! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8190#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
