  • v1.0.0 Changes

    🚀 Release notes:

    • We're calling this version 1.0.0 in preparation for Stackage LTS 4. Note, however, that this does not mean the code's API will be stable as this is primarily an end-user tool.

    ✨ Enhancements:

    • ➕ Added flag --profile flag: passed with stack build, it will enable profiling, and for --bench and --test it will generate a profiling report by passing +RTS -p to the executable(s). Great for using like stack build --bench --profile (remember that enabling profile will slow down your benchmarks by >4x). Run stack build --bench again to disable the profiling and get proper speeds
    • ➕ Added flag --trace flag: just like --profile, it enables profiling, but instead of generating a report for --bench and --test, prints out a stack trace on exception. Great for using like stack build --test --trace
    • 💻 Nix: all options can be overridden on command line #1483
    • 🏗 Nix: build environments (shells) are now pure by default.
    • 0️⃣ Make verbosity silent by default in script interpreter mode #1472
    • 👉 Show a message when resetting git commit fails #1453
    • 👌 Improve Unicode handling in project/package names #1337
    • 🛠 Fix ambiguity between a stack command and a filename to execute (prefer stack subcommands) #1471
    • 👌 Support multi line interpreter directive comments #1394
    • 🖐 Handle space separated pids in ghc-pkg dump (for GHC HEAD) #1509
    • ➕ Add ghci --no-package-hiding option #1517
    • stack new can download templates from URL #1466

    🐛 Bug fixes:

    • Nix: stack exec options are passed properly to the stack sub process #1538
    • Nix: specifying a shell-file works in any current working directory #1547
    • Nix: use --resolver argument
    • 🐳 Docker: fix missing image message and '--docker-auto-pull'
    • No HTML escaping for "stack new" template params #1475
    • Set permissions for generated .ghci script #1480
    • Restrict commands allowed in interpreter mode #1504
    • 👀 stack ghci doesn't see preprocessed files for executables #1347
    • ✅ All test suites run even when only one is requested #1550
    • Edge cases in broken templates give odd errors #1535
    • 🛠 Fix test coverage bug on windows

  • v0.1.10.1 Changes

    🐛 Bug fixes:

    • 🏗 stack image container did not actually build an image #1473

  • v0.1.10.0 Changes

    🚀 Release notes:

    • The Stack home page is now at haskellstack.org, which shows the documentation rendered by readthedocs.org. Note: this has necessitated some changes to the links in the documentation's markdown source code, so please check the links on the website before submitting a PR to fix them.
    • The locations of the Ubuntu and Debian package repositories have changed to have correct URL semantics according to Debian's guidelines #1378. The old locations will continue to work for some months, but we suggest that you adjust your /etc/apt/sources.list.d/fpco.list to the new location to avoid future disruption.
    • openSUSE and SUSE Linux Enterprise packages are now available, thanks to @mimi1vx. Note: there will be some lag before these pick up new versions, as they are based on Stackage LTS.

    Major changes:

    • 👌 Support for building inside a Nix-shell providing system dependencies #1285
    • ➕ Add optional GPG signing on stack upload --sign or with stack sig sign ...

    Other enhancements:

    • 📦 Print latest applicable version of packages on conflicts #508
    • 👌 Support for packages located in Mercurial repositories #1397
    • 🏗 Only run benchmarks specified as build targets #1412
    • 👌 Support git-style executable fall-through (stack something executes stack-something if present) #1433
    • GHCi now loads intermediate dependencies #584
    • --work-dir option for overriding .stack-work #1178
    • 👌 Support detailed-0.9 tests #1429
    • 🚦 Docker: improved POSIX signal proxying to containers #547

    🐛 Bug fixes:

    • 🏗 Show absolute paths in error messages in multi-package builds #1348
    • 🐳 Docker-built binaries and libraries in different path #911 #1367
    • 🐳 Docker: --resolver argument didn't effect selected image tag
    • GHCi: Spaces in filepaths caused module loading issues #1401
    • GHCi: cpp-options in cabal files weren't used #1419
    • Benchmarks couldn't be run independently of each other #1412
    • 🏗 Send output of building setup to stderr #1410

  • v0.1.8.0 Changes

    Major changes:

    • GHCJS can now be used with stackage snapshots via the new compiler field.
    • 🏁 Windows installers are now available: download them here #613
    • 🐳 Docker integration works with non-FPComplete generated images #531

    Other enhancements:

    • ➕ Added an allow-newer config option #922 #770
    • 🏗 When a Hackage revision invalidates a build plan in a snapshot, trust the snapshot #770
    • ➕ Added a stack config set resolver RESOLVER command. Part of work on #115
    • 🏁 stack setup can now install GHCJS on windows. See #1145 and #749
    • stack hpc report command added, which generates reports for HPC tix files
    • 🏗 stack ghci now accepts all the flags accepted by stack build. See #1186
    • 🏗 stack ghci builds the project before launching GHCi. If the build fails, try to launch GHCi anyway. Use stack ghci --no-build option to disable #1065
    • stack ghci now detects and warns about various circumstances where it is liable to fail. See #1270
    • ➕ Added require-docker-version configuration option
    • 👀 Packages will now usually be built along with their tests and benchmarks. See #1166
    • Relative local-bin-path paths will be relative to the project's root directory, not the current working directory. #1340
    • 📦 stack clean now takes an optional [PACKAGE] argument for use in multi-package projects. See #583
    • Ignore cabal_macros.h as a dependency #1195
    • Pad timestamps and show local time in --verbose output #1226
    • GHCi: Import all modules after loading them #995

    • 📦 stack new disallows package names with "words" consisting solely of numbers #1336
    • 🏗 stack build --fast turns off optimizations

    🐛 Bug fixes:

    • 🛠 Fix: Haddocks not copied for dependencies #1105
    • 🛠 Fix: Global options did not work consistently after subcommand #519
    • 🛠 Fix: 'stack ghci' doesn't notice that a module got deleted #1180

    • 🛠 Fix: Paths in GHC warnings not canonicalized, nor those for packages in subdirectories or outside the project root #1259
    • 🛠 Fix: unlisted files in tests and benchmarks trigger extraneous second build #838

  • v0.1.6.0 Changes

    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
    • 📇 Rename config files and clarify their purposes #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. 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
    • 👉 Use Haddock's --hyperlinked-source (crosslinked source), if available #1070
    • 👉 Use Stack-installed GHCs for stack init --solver #1072
    • 🆕 New experimental stack query command #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
    • 📦 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
    • 🐳 Docker: download or override location of stack executable to re-run in container #974
    • 🐳 Docker: when Docker Engine is remote, don't run containerized processes as host's UID/GID #194
    • 🐳 Docker: set-user option to enable/disable running containerized processes as host's UID/GID #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) 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
    • 🛠 Fix quoting of output failed command line arguments
    • 📦 Mark executable-only packages as installed when copied from cache #1043
    • Canonicalize temporary directory paths #1047
    • 🏗 Put code page fix inside the build function itself #1066
    • ➕ Add explicit-setup-deps option #1110, and change the default to the old behavior of using any package in the global and snapshot database #1025
    • 📦 Precompiled cache checks full package IDs on Cabal < 1.22 #1103
    • 📦 Pass -package-id to ghci #867
    • 📦 Ignore global packages when copying precompiled packages #1146

  • v0.1.5.0 Changes

    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
      • 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
    • stack setup takes a --stack-setup-yaml argument
    • --file-watch is more discerning about which files to rebuild for #912
    • 📦 stack path now supports --global-pkg-db and --ghc-package-path
    • --reconfigure flag #914 #946
    • Cached data is written with a checksum of its structure #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
    • Locking is now optional, and will be turned on by setting the STACK_LOCK environment variable to true #950
    • 📚 Create default stack.yaml with documentation comments and commented out options #226
    • ⚠ Out of memory warning if Cabal exits with -9 #947

    🐛 Bug fixes:

    • ↪ Hacky workaround for optparse-applicative issue with stack exec --help #806
    • 🏗 Build executables for local extra deps #920
    • copyFile can't handle directories #942
    • 👌 Support for spaces in Haddock interface files fpco/minghc#85
    • 🏗 Temporarily building against a "shadowing" local package? #992
    • 🛠 Fix Setup.exe name for --upgrade-cabal on Windows #1002
    • 🏗 Unlisted dependencies no longer trigger extraneous second build #838

  • v0.1.4.1 Changes

    🛠 Fix stack's own Haddocks. No changes to functionality (only comments updated).

  • v0.1.4.0 Changes

    Major changes:

    • 🚀 You now have more control over how GHC versions are matched, e.g. "use exactly this version," "use the specified minor version, but allow patches," or "use the given minor version or any later minor in the given major release." The default has switched from allowing newer later minor versions to a specific minor version allowing patches. For more information, see #736 and #784.
    • 👌 Support added for compiling with GHCJS
    • 🏗 stack can now reuse prebuilt binaries between snapshots. That means that, if you build package foo in LTS-3.1, that binary version can be reused in LTS-3.2, assuming it uses the same dependencies and flags. #878

    Other enhancements:

    • ➕ Added the --docker-env argument, to set environment variables in Docker container.
    • 🏗 Set locale environment variables to UTF-8 encoding for builds to avoid "commitBuffer: invalid argument" errors from GHC #793
    • Enable transliteration for encoding on stdout and stderr #824
    • ⬆️ By default, stack upgrade automatically installs GHC as necessary #797
    • ➕ Added the ghc-options field to stack.yaml #796
    • ➕ Added the extra-path field to stack.yaml
    • 🏁 Code page changes on Windows only apply to the build command (and its synonyms), and can be controlled via a command line flag (still defaults to on) #757
    • 📦 Implicitly add packages to extra-deps when a flag for them is set #807
    • 🏗 Use a precompiled Setup.hs for simple build types #801
    • ✅ Set --enable-tests and --enable-benchmarks optimistically #805
    • 🔧 --only-configure option added #820
    • 📦 Check for duplicate local package names
    • ✅ Stop nagging people that call stack test #845
    • --file-watch will ignore files that are in your VCS boring/ignore files #703
    • ➕ Add --numeric-version option

    🐛 Bug fixes:

    • 📦 stack init --solver fails if GHC_PACKAGE_PATH is present #860
    • ✅ stack solver and stack init --solver check for test suite and benchmark dependencies #862
    • More intelligent logic for setting UTF-8 locale environment variables #856
    • Create missing directories for stack sdist
    • Don't ignore .cabal files with extra periods #895
    • 🗄 Deprecate unused --optimizations flag
    • Truncated output on slow terminals #413

  • v0.1.3.1 Changes

    • Ignore disabled executables #763

  • v0.1.3.0 Changes

    Major changes:

    • Detect when a module is compiled but not listed in the cabal file (#32)
      • A warning is displayed for any modules that should be added to other-modules in the .cabal file
      • These modules are taken into account when determining whether a package needs to be built
    • Respect TemplateHaskell addDependentFile dependency changes (#105)
      • TH dependent files are taken into account when determining whether a package needs to be built.
    • ✅ Overhauled target parsing, added --test and --bench options #651

    • Set the HASKELL_DIST_DIR environment variable #524
    • 🏗 Track build status of tests and benchmarks #525
    • ✅ --no-run-tests #517
    • 🏗 Targets outside of root dir don't build #366
    • ✅ Upper limit on number of flag combinations to test #543
    • 👍 Fuzzy matching support to give better error messages for close version numbers #504
    • --local-bin-path global option. Use to change where binaries get placed on a --copy-bins #342
    • Custom snapshots #111
    • 📦 --force-dirty flag: Force treating all local packages as having dirty files (useful for cases where stack can't detect a file change)
    • 👍 GHC error messages: display file paths as absolute instead of relative for better editor integration
    • ➕ Add the --copy-bins option #569
    • ⚠ Give warnings on unexpected config keys #48
    • ✂ Remove Docker pass-host option
