Changelog

1.0.2

Release notes:

• Arch Linux: Stack has been adopted into the official community repository, so we will no longer be updating the AUR with new versions. See the install/upgrade guide for current download instructions.

Major changes:

• stack init and solver overhaul #1583

Other enhancements:

• Disable locale/codepage hacks when GHC >=7.10.3 #1552

• Specify which executables to include in images for stack image container docs
• Docker: pass supplemantary groups and umask into container
• If git fetch fails wipe the directory and try again from scratch #1418
• Warn if newly installed executables won’t be available on the PATH #1362
• stack.yaml: for stack image container, specify multiple images to generate, and which executables should be added to those images
• GHCI: add interactive Main selection #1068
• Care less about the particular name of a GHCJS sdist folder #1622
• Unified Enable/disable help messaging #1613

Bug fixes:

• Don’t share precompiled packages between GHC/platform variants and Docker #1551
• Properly redownload corrupted downloads with the correct file size. Mailing list discussion
• Gracefully handle invalid paths in error/warning messages #1561
• Nix: select the correct GHC version corresponding to the snapshot even when an abstract resolver is passed via --resolver on the command-line. #1641

• Use globaldb path for querying Cabal version #1647

1.0.0

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 overriden on command line #1483
• Nix: build environments (shells) are now pure by default.
• 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

0.1.10.1

Bug fixes:

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

0.1.10.0

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 eachother #1412
• Send output of building setup to stderr #1410

0.1.8.0

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, optimistically 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
• Add subcommand aliases: repl for ghci, and runhaskell for runghc #1241
• Add typo recommendations for unknown package identifiers #158
• Add stack path --local-hpc-root option
• Overhaul dependencies’ haddocks copying #1231
• Support for extra-package-dbs in ‘stack ghci’ #1229
• 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
• Rebuild when cabal file is changed
• 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

0.1.6.0

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

0.1.5.0

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

0.1.4.1

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

0.1.4.0

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 translitation 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

• 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
