Module documentation for 2.4.1.0

The Cabal library package

See the Cabal web site for more information.

If you also want the cabal command-line program, you need the cabal-install package in addition to this library.

Installing the Cabal library

If you already have the cabal program

In this case run:

$ cabal install

However, if you do not have an existing version of the cabal program, you first must install the Cabal library. To avoid this bootstrapping problem, you can install the Cabal library directly as described below.

Installing as a user (no root or administrator access)

ghc -threaded --make Setup
./Setup configure --user
./Setup build
./Setup install

Note the use of the --user flag at the configure step.

Compiling ‘Setup’ rather than using runghc Setup is much faster and works on Windows. For all packages other than Cabal itself, it is fine to use runghc.

This will install into $HOME/.cabal/ on Unix and into Documents and Settings\$User\Application Data\cabal\ on Windows. If you want to install elsewhere, use the --prefix= flag at the configure step.

Installing as root or Administrator

ghc -threaded --make Setup
./Setup configure
./Setup build
sudo ./Setup install

Compiling Setup rather than using runghc Setup is much faster and works on Windows. For all packages other than Cabal itself, it is fine to use runghc.

This will install into /usr/local on Unix, and on Windows it will install into $ProgramFiles/Haskell. If you want to install elsewhere, use the --prefix= flag at the configure step.

Using older versions of GHC and Cabal

It is recommended that you leave any pre-existing version of Cabal installed. In particular, it is essential you keep the version that came with GHC itself, since other installed packages require it (for instance, the “ghc” API package).

Prior to GHC 6.4.2, however, GHC did not deal particularly well with having multiple versions of packages installed at once. So if you are using GHC 6.4.1 or older and you have an older version of Cabal installed, you should probably remove it by running:

$ ghc-pkg unregister Cabal

or, if you had Cabal installed only for your user account, run:

$ ghc-pkg unregister Cabal --user

The filepath dependency

Cabal uses the filepath package, so it must be installed first. GHC version 6.6.1 and later come with filepath, however, earlier versions do not by default. If you do not already have filepath, you need to install it. You can use any existing version of Cabal to do that. If you have neither Cabal nor filepath, it is slightly harder but still possible.

Unpack Cabal and filepath into separate directories. For example:

tar -xzf filepath-1.1.0.0.tar.gz
tar -xzf Cabal-1.6.0.0.tar.gz

# rename to make the following instructions simpler:
mv filepath-1.1.0.0/ filepath/
mv Cabal-1.6.0.0/ Cabal/

cd Cabal
ghc -i../filepath -cpp --make Setup.hs -o ../filepath/setup
cd ../filepath/
./setup configure --user
./setup build
./setup install

This installs filepath so that you can install Cabal with the normal method.

Changes

2.4.1.0 Mikhail Glushenkov November 2018

  • Warnings in autogenerated files are now silenced (#5678).
  • Improved recompilation avoidance, especially when using GHC 8.6 (#5589).
  • Do not error on empty packagedbs in getInstalledPackages (#5516).

2.4.0.1 Mikhail Glushenkov September 2018

  • Allow arguments to be passed to Setup.hs haddock for build-type:configure (#5503).

2.4.0.0 Mikhail Glushenkov September 2018

  • Due to #5119, the cabal check warning for bounds on internal libraries has been disabled.
  • Distribution.Simple.Haddock now checks to ensure that it does not erroneously call Haddock with no target modules. (#5232, #5459).
  • Add getting (less general than to) Lens combinator, non) and an optics to access the modules in a component of a PackageDescription by the ComponentName: componentBuildInfo and componentModules
  • Add readGhcEnvironmentFile to parse GHC environment files.
  • Drop support for GHC 7.4, since it is out of our support window (and has been for over a year!)
  • Deprecate preSDist, sDistHook, and postSDist in service of new-sdist, since they violate key invariants of the new-build ecosystem. Use autogen-modules and build-tool-depends instead. (#5389).
  • Added --repl-options flag to Setup repl used to pass flags to the underlying repl without affecting the LocalBuildInfo (#4247, #5287)
  • KnownExtension: added new extensions BlockArguments (#5101), NumericUnderscores (#5130, QuantifiedConstraints, and StarIsType.
  • buildDepends is removed from PackageDescription. It had long been uselessly hanging about as top-level build-depends already got put into per-component condition trees anyway. Now it’s finally been put out of its misery (#4383).
  • Added Eta to CompilerFlavor and to known compilers.
  • cabal haddock now generates per-component documentation (#5226).
  • Wildcard improvements:
    • Allow ** wildcards in data-files, extra-source-files and extra-doc-files. These allow a limited form of recursive matching, and require cabal-version: 2.4. (#5284, #3178, et al.)
    • With cabal-version: 2.4, when matching a wildcard, the requirement for the full extension to match exactly has been loosened. Instead, if the wildcard’s extension is a suffix of the file’s extension, the file will be selected. For example, previously foo.en.html would not match *.html, and foo.solaris.tar.gz would not match *.tar.gz, but now both do. This may lead to files unexpectedly being included by sdist; please audit your package descriptions if you rely on this behaviour to keep sensitive data out of distributed packages (#5372, #784, #5057).
    • Wildcard syntax errors (misplaced *, etc), wildcards that refer to missing directoies, and wildcards that do not match anything are now all detected by cabal check.
    • Wildcard (‘globbing’) functions have been moved from Distribution.Simple.Utils to Distribution.Simple.Glob and have been refactored.
  • Fixed cxx-options and cxx-sources buildinfo fields for separate compilation of C++ source files to correctly build and link non-library components (#5309).
  • Reduced warnings generated by hsc2hs and c2hs when cxx-options field is present in a component.
  • cabal check now warns if -j is used in ghc-options in a Cabal file. (#5277)
  • install-includes now works as expected with foreign libraries (#5302).
  • Removed support for JHC.
  • Options listed in ghc-options, cc-options, ld-options, cxx-options, cpp-options are not deduplicated anymore (#4449).
  • Deprecated cabal hscolour in favour of cabal haddock --hyperlink-source (#5236).
  • Recognize powerpc64le as architecture PPC64.
  • Cabal now deduplicates more -I and -L and flags to avoid E2BIG (#5356).
  • With build-type: configure, avoid using backslashes to delimit path components on Windows and warn about other unsafe characters in the path to the source directory on all platforms (#5386).
  • Distribution.PackageDescription.Check.checkPackageFiles now accepts a Verbosity argument.
  • Added a parameter to Distribution.Backpack.ConfiguredComponent.toConfiguredComponent in order to fix #5409.
  • Partially silence abi-depends warnings (#5465).
  • Foreign libraries are now linked against the threaded RTS when the ‘ghc-options: -threaded’ flag is used (#5431).
  • Pass command line arguments to hsc2hs using response files when possible (#3122).

2.2.0.1 Mikhail Glushenkov March 2018

  • Fix checkPackageFiles for relative directories (#5206)

2.2.0.0 Mikhail Glushenkov March 2018

  • The 2.2 migration guide gives advice on adapting Custom setup scripts to backwards-incompatible changes in this release: https://github.com/haskell/cabal/wiki/2.2-migration-guide.
  • New Parsec-based parser for .cabal files is now the default. This brings memory consumption and speed improvements, as well as making new syntax extensions easier to implement.
  • Support for common stanzas (#4751).
  • Added elif-conditionals to .cabal syntax (#4750).
  • The package license information can now be specified using the SPDX syntax. This requires setting cabal-version to 2.2+ (#2547, #5050).
  • Support for GHC’s numeric -g debug levels (#4673).
  • Compilation with section splitting is now supported via the --enable-split-sections flag (#4819)
  • Fields with mandatory commas (e.g. build-depends) may now have a leading or a trailing comma (either one, not both) (#4953)
  • Added virtual-modules field, to allow modules that are not built but registered (#4875).
  • Use better defaulting for build-type; rename PackageDescription’s buildType field to buildTypeRaw and introduce new buildType function (#4958)
  • D.T.PackageDescription.allBuildInfo now returns all build infos, not only for buildable components (#5087).
  • Removed UnknownBuildType constructor from BuildType (#5003).
  • Added HexFloatLiterals to KnownExtension.
  • Cabal will no longer try to build an empty set of inputModules (#4890).
  • copyComponent and installIncludeFiles will now look for include headers in the build directory (dist/build/... by default) as well (#4866).
  • Added cxx-options and cxx-sources buildinfo fields for separate compilation of C++ source files (#3700).
  • Removed unused --allow-newer/--allow-older support from Setup configure (#4527).
  • Changed FlagAssignment to be an opaque newtype (#4849).
  • Changed rawSystemStdInOut to use proper type to represent binary and textual data; new Distribution.Utils.IOData module; removed obsolete startsWithBOM, fileHasBOM, fromUTF8, and toUTF8 functions; add new toUTF8BS/toUTF8LBS encoding functions. (#4666)
  • Added a cabal check warning when the .cabal file name does not match package name (#4592).
  • The ar program now receives its arguments via a response file (@file). Old behaviour can be restored with --disable-response-files argument to configure or install (#4596).
  • Added .Lens modules, with optics for package description data types (#4701).
  • Support for building with Win32 version 2.6 (#4835).
  • Change compilerExtensions and ghcOptExtensionMap to contain Maybe Flags, since a supported extention can lack a flag (#4443).
  • Pretty-printing of .cabal files is slightly different due to parser changes. For an example, see https://mail.haskell.org/pipermail/cabal-devel/2017-December/010414.html.
  • --hyperlink-source now uses Haddock’s hyperlinker backend when Haddock is new enough, falling back to HsColour otherwise.
  • D.S.defaultHookedPackageDesc has been deprecated in favour of D.S.findHookedPackageDesc (#4874).
  • D.S.getHookedBuildInfo now takes an additional parameter specifying the build directory path (#4874).
  • Emit warning when encountering unknown GHC versions (#415).

2.0.1.1 Mikhail Glushenkov December 2017

  • Don’t pass other-modules to stub executable for detailed-0.9 (#4918).
  • Hpc: Use relative .mix search paths (#4917).

2.0.1.0 Mikhail Glushenkov November 2017

  • Support for GHC’s numeric -g debug levels (#4673).
  • Added a new Distribution.Verbosity.modifyVerbosity combinator (#4724).
  • Added a new cabal check warning about unused, undeclared or non-Unicode flags. Also, it warns about leading dash, which is unusable but accepted if it’s unused in conditionals. (#4687)
  • Modify allBuildInfo to include foreign library info (#4763).
  • Documentation fixes.

2.0.0.2 Mikhail Glushenkov July 2017

  • See http://coldwa.st/e/blog/2017-09-09-Cabal-2-0.html for more detailed release notes.
  • The 2.0 migration guide gives advice on adapting Custom setup scripts to backwards-incompatible changes in this release: https://github.com/haskell/cabal/wiki/2.0-migration-guide
  • Add CURRENT_PACKAGE_VERSION to cabal_macros.h (#4319)
  • Dropped support for versions of GHC earlier than 6.12 (#3111).
  • GHC compatibility window for the Cabal library has been extended to five years (#3838).
  • Convenience/internal libraries are now supported (#269). An internal library is declared using the stanza library 'libname'. Packages which use internal libraries can result in multiple registrations; thus --gen-pkg-config can now output a directory of registration scripts rather than a single file.
  • Backwards incompatible change to preprocessor interface: the function in PPSuffixHandler now takes an additional ComponentLocalBuildInfo specifying the build information of the component being preprocessed.
  • Backwards incompatible change to cabal_macros.h (#1893): we now generate a macro file for each component which contains only information about the direct dependencies of that component. Consequently, dist/build/autogen/cabal_macros.h contains only the macros for the library, and is not generated if a package has no library; to find the macros for an executable named foobar, look in dist/build/foobar/autogen/cabal_macros.h. Similarly, if you used autogenModulesDir you should now use autogenComponentModulesDir, which now requires a ComponentLocalBuildInfo argument as well in order to disambiguate which component the autogenerated files are for.
  • Backwards incompatible change to Component: TestSuite and Benchmark no longer have testEnabled and benchmarkEnabled. If you used enabledTests or enabledBenchmarks, please instead use enabledTestLBIs and enabledBenchLBIs (you will need a LocalBuildInfo for these functions.) Additionally, the semantics of withTest and withBench have changed: they now iterate over all buildable such components, regardless of whether or not they have been enabled; if you only want enabled components, use withTestLBI and withBenchLBI. finalizePackageDescription is deprecated: its replacement finalizePD now takes an extra argument ComponentRequestedSpec which specifies what components are to be enabled: use this instead of modifying the Component in a GenericPackageDescription. (As it’s not possible now, finalizePackageDescription will assume tests/benchmarks are disabled.) If you only need to test if a component is buildable (i.e., it is marked buildable in the Cabal file) use the new function componentBuildable.
  • Backwards incompatible change to PackageName (#3896): PackageName is now opaque; conversion to/from String now works via (old) unPackageName and (new) mkPackageName functions.
  • Backwards incompatible change to ComponentId (#3917): ComponentId is now opaque; conversion to/from String now works via unComponentId and mkComponentId functions.
  • Backwards incompatible change to AbiHash (#3921): AbiHash is now opaque; conversion to/from String now works via unAbiHash and mkAbiHash functions.
  • Backwards incompatible change to FlagName (#4062): FlagName is now opaque; conversion to/from String now works via unFlagName and mkFlagName functions.
  • Backwards incompatible change to Version (#3905): Version is now opaque; conversion to/from [Int] now works via versionNumbers and mkVersion functions.
  • Add support for --allow-older (dual to --allow-newer) (#3466)
  • Improved an error message for process output decoding errors (#3408).
  • getComponentLocalBuildInfo, withComponentsInBuildOrder and componentsInBuildOrder are deprecated in favor of a new interface in Distribution.Types.LocalBuildInfo.
  • New autogen-modules field. Modules that are built automatically at setup, like Paths_PACKAGENAME or others created with a build-type custom, appear on other-modules for the Library, Executable, Test-Suite or Benchmark stanzas or also on exposed-modules for libraries but are not really on the package when distributed. This makes commands like sdist fail because the file is not found, so with this new field modules that appear there are treated the same way as Paths_PACKAGENAME was and there is no need to create complex build hooks. Just add the module names on other-modules and exposed-modules as always and on the new autogen-modules besides. (#3656).
  • New ./Setup configure flag --cabal-file, allowing multiple .cabal files in a single directory (#3553). Primarily intended for internal use.
  • Macros in cabal_macros.h are now ifndef’d, so that they don’t cause an error if the macro is already defined. (#3041)
  • ./Setup configure now accepts a single argument specifying the component to be configured. The semantics of this mode of operation are described in https://github.com/ghc-proposals/ghc-proposals/pull/4
  • Internal build-tools dependencies are now added to PATH upon invocation of GHC, so that they can be conveniently used via -pgmF. (#1541)
  • Add support for new caret-style version range operator ^>= (#3705)
  • Verbosity -v now takes an extended format which allows specifying exactly what you want to be logged. The format is [silent|normal|verbose|debug] flags, where flags is a space separated list of flags. At the moment, only the flags +callsite and +callstack are supported; these report the call site/stack of a logging output respectively (these are only supported if Cabal is built with GHC 8.0/7.10.2 or greater, respectively).
  • New Distribution.Utils.ShortText.ShortText type for representing short text strings compactly (#3898)
  • Cabal no longer supports using a version bound to disambiguate between an internal and external package (#4020). This should not affect many people, as this mode of use already did not work with the dependency solver.
  • Support for “foreign libraries” (#2540), which are Haskell libraries intended to be used by foreign languages like C. Foreign libraries only work with GHC 7.8 and later.
  • Added a technical preview version of integrated doctest support (#4480).
  • Added a new scope field to the executable stanza. Executables with scope: private get installed into $libexecdir/$libexecsubdir. Additionally $libexecdir now has a subdir structure similar to $lib(sub)dir to allow installing private executables of different packages and package versions alongside one another. Private executables are those that are expected to be run by other programs rather than users. (#3461)

  • Library support for multi-instance package DBs (#2948).
  • Improved the ./Setup configure solver (#3082, #3076).
  • The --allow-newer option can be now used with ./Setup configure (#3163).

  • Macros VERSION_$pkgname and MIN_VERSION_$pkgname are now also generated for the current package. (#3235).
  • Backpack is supported! Two new fields supported in Cabal files: signatures and mixins; and a new flag to setup scripts, --instantiate-with. See https://github.com/ezyang/ghc-proposals/blob/backpack/proposals/0000-backpack.rst for more details.

0.4 Isaac Jones Sun Jan 16 2005

  • Much thanks to all the awesome fptools hackers who have been working hard to build the Haskell Cabal!

  • Interface Changes:

    • WARNING: this is a pre-release and the interfaces are still likely to change until we reach a 1.0 release.

    • Instead of Package.description, you should name your description files .cabal. In particular, we suggest that you name it .cabal, but this is not enforced (yet). Multiple .cabal files in the same directory is an error, at least for now.

    • ./setup install --install-prefix is gone. Use ./setup copy --copy-prefix instead.

    • The Modules field is gone. Use hidden-modules, exposed-modules, and executable-modules.

    • Build-depends is now a package-only field, and can’t go into executable stanzas. Build-depends is a package-to-package relationship.

    • Some new fields. Use the Source.

  • New Features

    • Cabal is now included as a package in the CVS version of fptools. That means it’ll be released as -package Cabal in future versions of the compilers, and if you are a bleeding-edge user, you can grab it from the CVS repository with the compilers.

    • Hugs compatibility and NHC98 compatibility should both be improved.

    • Hooks Interface / Autoconf compatibility: Most of the hooks interface is hidden for now, because it’s not finalized. I have exposed only defaultMainWithHooks and defaultUserHooks. This allows you to use a ./configure script to preprocess foo.buildinfo, which gets merged with foo.cabal. In future releases, we’ll expose UserHooks, but we’re definitely going to change the interface to those. The interface to the two functions I’ve exposed should stay the same, though.

    • ./setup haddock is a baby feature which pre-processes the source code with hscpp and runs haddock on it. This is brand new and hardly tested, so you get to knock it around and see what you think.

    • Some commands now actually implement verbosity.

    • The preprocessors have been tested a bit more, and seem to work OK. Please give feedback if you use these.

0.3 Isaac Jones Sun Jan 16 2005

  • Unstable snapshot release
  • From now on, stable releases are even.

0.2 Isaac Jones

  • Adds more HUGS support and preprocessor support.
