#507: display available flags based on the .cabal file ---------------------------------+------------------------------------------ Reporter: guest | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.6.0.1 Severity: minor | Resolution: Keywords: | Difficulty: normal Ghcversion: | Platform: ---------------------------------+------------------------------------------ Changes (by duncan): * difficulty: unknown => normal Comment: Right. Should not be too hard. After all we do this already in the `cabal info` output. eg: {{{ $ cabal info darcs * darcs (program and library) Synopsis: a distributed, interactive, smart revision control system [..snip..] Source repo: http://darcs.net/ Executables: darcs Flags: curl, curl-pipelining, libwww, http, external-bytestring, external-zlib, haskeline, terminfo, curses, type-witnesses, color, base3 }}} Of course when configuring a single package we want to see the description of each of these flags, if they're available. We could do similarly for `cabal info` when run in the current dir with a local .cabal package. Printing it in `cabal configure --help` is technically a bit harder. Perhaps the help string for `--flags` should refer to `cabal info`. Or perhaps that's just to annoying and we should work out how to get it to read the local `.cabal` file before producing the help output (but not failing if one is not present or if it cannot be parsed). -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/507#comment:1 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
