[Hackage] #931: Support building source trees with many packages
#931: Support building source trees with many packages ---------------------------------+------------------------------------------ Reporter: tibbe | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: 1.10.2.0 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ A not uncommon use case is building a package against a set of dependencies that exist in (unreleased) source form. For example, given two packages: {{{ $ ls hashable unordered-containers }}} I'd like to be able to {{{ $ cd unordered-containers cabal build --root=.. }}} Cabal should then recursively traverse directories from `--root`, looking for .cabal files to use when fulfilling dependencies (i.e. in this case it'd find `hashable`.) Those dependencies should also be marked as preferred to any Hackage versions of the package with the same version number. It'd also be convenient to add several `--root` flags, so one can specify specific packages to use in source form (without using e.g. the user's complete `~/src` directory.) {{{ $ cd unordered-containers cabal build --root=../hashable --root=../text }}} -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/931 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

Note that #734 is about multiple .cabal files in the same dir, which isn't what this ticket is requesting. #409 is closer. I'm not sure I like the proposed UI, but the general idea is right. It should be easy to define local environments for finding packages (either local build trees, local or remote tarballs). My thoughts on this are that we need an extended package index format which allows links to local build trees and tarballs, then we need a UI to create and manipulate that environment. This approach is much more similar to cabal-dev which lets you add packages into a local index, but extended so that instead of just taking snapshots of build trees as tarballs we can link directly to local build trees. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/931#comment:3 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
