Thanks Simon, I fixed the "verboseCommands" typo.
Regarding various available predicates: indeed, we don't currently have a comprehensive description -- I've opened an issue for this and will hopefully fix it soon. In the meanwhile, there are a few examples of predicates in the rest of the doc/user-settings.md document, for example here: https://github.com/snowleopard/hadrian/blob/master/doc/user-settings.md#command-line-arguments. The `input` and `output` predicates accept Shake's `FilePattern` as parameters -- see the documentation for it here: https://hackage.haskell.org/package/shake-0.16.4/docs/Development-Shake.html#v:-63--61--61- Cheers, Andrey -----Original Message----- From: Simon Peyton Jones [mailto:simo...@microsoft.com] Sent: 04 September 2018 16:49 To: Andrey Mokhov <andrey.mok...@newcastle.ac.uk>; Alp Mestanogullari <a...@well-typed.com> Cc: ghc-devs <ghc-devs@haskell.org> Subject: RE: Hadrian Very confusingly https://github.com/snowleopard/hadrian/blob/master/doc/user-settings.md#verbose-command-lines speaks about verboseCommmands PLURAL, whereas it should say verboseCommand SINGLUAR. Moreover, what is the language things you can say (i.e. where is it documented). The "//" business, and what patterns can occur. What things other than "//" can you have? What about 'input' etc?
