Hello Simon, Andrey, For “How to use Hadrian wikipage”, maybe Simon wanted this one from the GHC Wiki:
https://ghc.haskell.org/trac/ghc/wiki/Building/Hadrian/QuickStart It does mention the verbose flag, but does not really explain that you can get what Simon wants, I believe. -- Best wishes, Artem чт, 30 авг. 2018 г. в 7:25, Andrey Mokhov <andrey.mok...@newcastle.ac.uk>: > Simon, > > If you want to see all command lines, you can pass '--verbose' or '-V' > flag to Hadrian and it will then print out everything it does. > > But you can also choose which particular command lines to print in > UserSettings, see: > > > https://github.com/snowleopard/hadrian/blob/master/doc/user-settings.md#verbose-command-lines > > So, you can do: > > verboseCommand = input "//GHC/Real.hs" > > Or, alternatively, > > verboseCommand = output "//GHC/Real.hi" > > Both should produce the same result (in theory). > > In general, we have the following documents on Hadrian: > > The README: https://github.com/snowleopard/hadrian/blob/master/README.md > How to use UserSettings: > https://github.com/snowleopard/hadrian/blob/master/doc/user-settings.md > An overview of build flavours: > https://github.com/snowleopard/hadrian/blob/master/doc/flavours.md > > I hope the more Hadrian gets used, the more complete the documentation > will become. > > Cheers, > Andrey > > From: Simon Peyton Jones [mailto:simo...@microsoft.com] > Sent: 30 August 2018 12:19 > To: Simon Peyton Jones <simo...@microsoft.com>; Alp Mestanogullari < > a...@well-typed.com>; Andrey Mokhov <andrey.mok...@newcastle.ac.uk> > Cc: ghc-devs <ghc-devs@haskell.org> > Subject: RE: Hadrian > > Sigh.
