#225: allow installing just specific bits, like just docs ----------------------------+----------------------------------------------- Reporter: duncan | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: | ----------------------------+----------------------------------------------- Sometimes people would like to build and install just part of a cabal project, e.g. the documentation or one of the libraries or binaries. Specific use-cases are packaging for OS distro's and generating Haddock docs for code that was installed without it (cf the current state of Debian-stable). Igloo proposes the following user interface: ----- As long as docs, license and binaries can be (de)selected individually I don't really mind. If you want a concrete suggestion, we could have `--foo` and `--no-foo` for each thing, with the default being `--all` and the command line being processed left-to-right, e.g. {{{ cabal install --no-haddock-interfaces --docs --no-html }}} would install * all (which wouldn't actually contain anything) * docs (which wouldn't actually contain anything) * haddock-interfaces * license * everything under binaries ----- I broadly agree, but am slightly concerned there are dependencies amongst the various things that his syntax does not respect (e.g. one may need to install the libraries - e.g. one depending on a foreign library - in order to get a binary working). So either we have to vet the command lines or coarsen the flags. I hope Duncan and Igloo can draw on their packaging experience and determine what is actually useful. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/225 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
