New version released of Stack, a build tool. See README https://github.com/commercialhaskell/stack/tree/release#how-to-install for installation and upgrade instructions. Major changes: - “stack setup” now supports building and booting GHCJS from source tarball. - On Windows, build directories no longer display “pretty” information (like x86_64-windows/Cabal-1.22.4.0), but rather a hash of that content. The reason is to avoid the 260 character path limitation on Windows. See #1027 https://github.com/commercialhaskell/stack/pull/1027 - Rename config files and clarify their purposes #969 https://github.com/commercialhaskell/stack/issues/969 - ~/.stack/stack.yaml → ~/.stack/config.yaml - ~/.stack/global → ~/.stack/global-project - /etc/stack/config → /etc/stack/config.yaml - Old locations still supported, with deprecation warnings - New command “stack eval CODE”, which evaluates to “stack exec ghc — -e CODE”. Other enhancements: - No longer install git on Windows #1046 https://github.com/commercialhaskell/stack/issues/1046. You can still get this behavior by running the following yourself: stack exec -- pacman -Sy --noconfirm git. - Typing enter during —file-watch triggers a rebuild #1023 https://github.com/commercialhaskell/stack/pull/1023 - Use Haddock’s --hyperlinked-source (crosslinked source), if available #1070 https://github.com/commercialhaskell/stack/pull/1070 - Use Stack-installed GHCs for stack init --solver #1072 https://github.com/commercialhaskell/stack/issues/1072 - New experimental stack query command #1087 https://github.com/commercialhaskell/stack/issues/1087 - By default, stack no longer rebuilds a package due to GHC options changes. This behavior can be tweaked with the rebuild-ghc-options setting. #1089 https://github.com/commercialhaskell/stack/issues/1089 - By default, ghc-options are applied to all local packages, not just targets. This behavior can be tweaked with the apply-ghc-options setting. #1089 https://github.com/commercialhaskell/stack/issues/1089 - Docker: download or override location of stack executable to re-run in container #974 https://github.com/commercialhaskell/stack/issues/974 - Docker: when Docker Engine is remote, don’t run containerized processes as host’s UID/GID #194 https://github.com/commercialhaskell/stack/issues/194 - Docker: set-user option to enable/disable running containerized processes as host’s UID/GID #194 https://github.com/commercialhaskell/stack/issues/194 - Custom Setup.hs files are now precompiled instead of interpreted. This should be a major performance win for certain edge cases (biggest example: building Cabal itself https://github.com/commercialhaskell/stack/issues/1041) while being either neutral or a minor slowdown for more common cases. - stack test --coverage now also generates a unified coverage report for multiple test-suites / packages. In the unified report, test-suites can contribute to the coverage of other packages. Bug fixes: - Ignore stack-built executables named ghc #1052 https://github.com/commercialhaskell/stack/issues/1052 - Fix quoting of output failed command line arguments - Mark executable-only packages as installed when copied from cache #1043 https://github.com/commercialhaskell/stack/pull/1043 - Canonicalize temporary directory paths #1047 https://github.com/commercialhaskell/stack/pull/1047 - Put code page fix inside the build function itself #1066 https://github.com/commercialhaskell/stack/issues/1066 - Add explicit-setup-deps option #1110 https://github.com/commercialhaskell/stack/issues/1110, and change the default to the old behavior of using any package in the global and snapshot database #1025 https://github.com/commercialhaskell/stack/issues/1025 - Precompiled cache checks full package IDs on Cabal < 1.22 #1103 https://github.com/commercialhaskell/stack/issues/1103 - Pass -package-id to ghci #867 https://github.com/commercialhaskell/stack/issues/867 - Ignore global packages when copying precompiled packages #1146 https://github.com/commercialhaskell/stack/issues/1146 ​
