New version released of stack, a build tool. See README https://github.com/commercialhaskell/stack#how-to-install for installation and upgrade instructions. Note: the binary tarballs’ contents have changed, and they now enclose their contents in a directory, and include documentation. If you have a script that should only extract the stack executable, use something like tar xzf stack-0.1.5.0-x86_64-osx.tar.gz --strip-components=1 stack-0.1.5.0-x86_64-osx/stack. MinGHC installers https://github.com/fpco/minghc/releases have also been updated to include this version of stack (and will continue to be updated for future releases). Major changes: - On Windows, we now use a full MSYS2 installation in place of the previous PortableGit. This gives you access to the pacman package manager for more easily installing libraries. - Support for custom GHC binary distributions #530 https://github.com/commercialhaskell/stack/issues/530 - ghc-variant option in stack.yaml to specify the variant (also --ghc-variant command-line option) - setup-info in stack.yaml, to specify where to download custom binary distributions (also --ghc-bindist command-line option) - Note: On systems with libgmp4 (aka libgmp.so.3), such as CentOS 6, you may need to re-run stack setup due to the centos6 GHC bindist being treated like a variant - A new --pvp-bounds flag to the sdist and upload commands allows automatic adding of PVP upper and/or lower bounds to your dependencies Other enhancements: - Adapt to upcoming Cabal installed package identifier format change #851 https://github.com/commercialhaskell/stack/issues/851 - stack setup takes a --stack-setup-yaml argument - --file-watch is more discerning about which files to rebuild for #912 https://github.com/commercialhaskell/stack/issues/912 - stack path now supports --global-pkg-db and --ghc-package-path - --reconfigure flag #914 https://github.com/commercialhaskell/stack/issues/914 #946 https://github.com/commercialhaskell/stack/issues/946 - Cached data is written with a checksum of its structure #889 https://github.com/commercialhaskell/stack/issues/889 - Fully removed --optimizations flag - Added --cabal-verbose flag - Added --file-watch-poll flag for polling instead of using filesystem events (useful for running tests in a Docker container while modifying code in the host environment. When code is injected into the container via a volume, the container won’t propagate filesystem events). - Give a preemptive error message when -prof is given as a GHC option #1015 https://github.com/commercialhaskell/stack/issues/1015 - Locking is now optional, and will be turned on by setting the STACK_LOCK environment variable to true #950 https://github.com/commercialhaskell/stack/issues/950 - Create default stack.yaml with documentation comments and commented out options #226 https://github.com/commercialhaskell/stack/issues/226 - Out of memory warning if Cabal exits with -9 #947 https://github.com/commercialhaskell/stack/issues/947 Bug fixes: - Hacky workaround for optparse-applicative issue with stack exec --help #806 https://github.com/commercialhaskell/stack/issues/806 - Build executables for local extra deps #920 https://github.com/commercialhaskell/stack/issues/920 - copyFile can’t handle directories #942 https://github.com/commercialhaskell/stack/pull/942 - Support for spaces in Haddock interface files fpco/minghc#85 https://github.com/fpco/minghc/issues/85 - Temporarily building against a “shadowing” local package? #992 https://github.com/commercialhaskell/stack/issues/992 - Fix Setup.exe name for —upgrade-cabal on Windows #1002 https://github.com/commercialhaskell/stack/issues/1002 - Unlisted dependencies no longer trigger extraneous second build #838 https://github.com/commercialhaskell/stack/issues/838
