DESCRIPTION
Cabal is the standard package system for Haskell software. It helps people to configure, build and install Haskell software and to distribute it easily to other users and developers. The command line cabal tool (also referred to as cabal-install) helps with installing existing packages and developing new packages. It can be used to work with local packages or to install packages from online package archives, including automatically installing dependencies. By default it is configured to use Hackage, which is Haskell's central package archive that contains thousands of libraries and applications in the Cabal package format.

COMMANDS
cabal list Usage: cabal list [FLAGS]
   or: cabal list [FLAGS] STRINGS List all packages, or all packages matching one of the search strings. If there is a sandbox in the current directory and config:ignore-sandbox is False, use the sandbox package database. Otherwise, use the package database specified with --package-db. If not specified, use the user package database. Examples:
  cabal list pandoc
    Will find pandoc, pandoc-citeproc, pandoc-lens, ... Flags:
    -v, --verbose [n]
        Control verbosity (n is 0--3, default verbosity level is 1)
    --installed
        Only print installed packages
    --simple-output
        Print in a easy-to-parse format
    --package-db DB
        Append the given package database to the list of package databases used (to satisfy dependencies and register into). May be a specific file, 'global' or 'user'. The initial list is ['global'], ['global', 'user'], or ['global', $sandbox], depending on context. Use 'clear' to reset the list to empty. See the user guide for details.
cabal info Usage: cabal info [FLAGS] PACKAGES If there is a sandbox in the current directory and config:ignore-sandbox is False, use the sandbox package database. Otherwise, use the package database specified with --package-db. If not specified, use the user package database. Flags:
    -v, --verbose [n]
        Control verbosity (n is 0--3, default verbosity level is 1)
    --package-db DB
        Append the given package database to the list of package databases used (to satisfy dependencies and register into). May be a specific file, 'global' or 'user'. The initial list is ['global'], ['global', 'user'], or ['global', $sandbox], depending on context. Use 'clear' to reset the list to empty. See the user guide for details.
cabal fetch Usage: cabal fetch [FLAGS] PACKAGES Note that it currently is not possible to fetch the dependencies for a package in the current directory. Flags:
    -v, --verbose [n]
        Control verbosity (n is 0--3, default verbosity level is 1)
    --dependencies, --deps
        Resolve and fetch dependencies (default)
    --no-dependencies, --no-deps
        Ignore dependencies
    --dry-run
        Do not install anything, only print what would be installed.
    --enable-tests
    --disable-tests
        dependency checking and compilation for test suites listed in the package description file.
    --enable-benchmarks
    --disable-benchmarks
        dependency checking and compilation for benchmarks listed in the package description file.
    --solver SOLVER
        Select dependency solver to use (default: modular). Choices: modular.
    --max-backjumps NUM
        Maximum number of backjumps allowed while solving (default: 4000). Use a negative number to enable unlimited backtracking. Use 0 to disable backtracking completely.
    --reorder-goals
    --no-reorder-goals
        Try to reorder goals according to certain heuristics. Slows things down on average, but may make backtracking faster for some packages.
    --count-conflicts
    --no-count-conflicts
        Try to speed up solving by preferring goals that are involved in a lot of conflicts (default).
    --fine-grained-conflicts
    --no-fine-grained-conflicts
        Skip a version of a package if it does not resolve the conflicts encountered in the last version, as a solver optimization (default).
    --minimize-conflict-set
    --no-minimize-conflict-set
        When there is no solution, try to improve the error message by finding a minimal conflict set (default: false). May increase run time significantly.
    --independent-goals
    --no-independent-goals
        Treat several goals on the command line as independent. If several goals depend on the same package, different versions can be chosen.
    --shadow-installed-packages
    --no-shadow-installed-packages
        If multiple package instances of the same version are installed, treat all but one as shadowed.
    --strong-flags
    --no-strong-flags
        Do not defer flag choices (this used to be the default in cabal-install <= 1.20).
    --allow-boot-library-installs
    --no-allow-boot-library-installs
        Allow cabal to install base, ghc-prim, integer-simple, integer-gmp, and template-haskell.
    --reject-unconstrained-dependencies none|all
        Require these packages to have constraints on them if they are to be selected (default: none).
cabal get Usage: cabal get [PACKAGES] Creates a local copy of a package's source code. By default it gets the source tarball and unpacks it in a local subdirectory. Alternatively, with -s it will get the code from the source repository specified by the package. Examples:
  cabal get hlint
    Download the latest stable version of hlint;
  cabal get lens --source-repository=head
    Download the source repository (i.e. git clone from github). Flags:
    -v, --verbose [n]
        Control verbosity (n is 0--3, default verbosity level is 1)
    -d, --destdir PATH
        Where to place the package source, defaults to the current directory.
    -s, --source-repository [[head|this|...]]
        Copy the package's source repository (ie git clone, darcs get, etc as appropriate).
    --index-state STATE
        Use source package index state as it existed at a previous time. Accepts unix-timestamps (e.g. '@1474732068'), ISO8601 UTC timestamps (e.g. '2016-09-24T17:47:48Z'), or 'HEAD' (default: 'HEAD'). This determines which package versions are available as well as .cabal file revision is selected (unless --pristine is used).
    --pristine
        Unpack the original pristine tarball, rather than updating the .cabal file with the latest revision from the package archive.
cabal check Usage: cabal check [FLAGS] Expects a .cabal package file in the current directory. The checks correspond to the requirements to packages on Hackage. If no errors and warnings are reported, Hackage will accept this package. Flags:
    -v, --verbose [n]
        Control verbosity (n is 0--3, default verbosity level is 1)
cabal upload Usage: cabal upload [FLAGS] TARFILES You can store your Hackage login in the ~/.cabal/config file Relevant global configuration keys:
  username
  password Flags:
    -v, --verbose [n]
        Control verbosity (n is 0--3, default verbosity level is 1)
    --publish
        Publish the package instead of uploading it as a candidate.
    -d, --documentation
        Upload documentation instead of a source package. By default, this uploads documentation for a package candidate. To upload documentation for a published package, combine with --publish.
    -u, --username USERNAME
        Hackage username.
    -p, --password PASSWORD
        Hackage password.
    -P, --password-command PASSWORD

    -u, --username USERNAME
        Hackage username.
    -p, --password PASSWORD
        Hackage password.
cabal init Usage: cabal init [FLAGS] Create a .cabal, Setup.hs, and optionally a LICENSE file. Calling init with no arguments creates an executable, guessing as many options as possible. The interactive mode can be invoked by the -i/--interactive flag, which will try to guess as much as possible and prompt you for the rest. You can change init to always be interactive by setting the interactive flag in your configuration file. Command-line arguments are provided for scripting purposes. Flags:
    -i, --interactive
    -n, --non-interactive
        interactive mode.

cabal configure Usage: cabal configure [FLAGS] Adjust how the project is built by setting additional package flags and other flags. The configuration options are written to the 'cabal.project.local' file (or configuration from the 'cabal.project' file (if any). This combination is used as the project configuration for all other commands (such as 'build', The configure command also checks that the project configuration will work. In particular it checks that there is a consistent set of dependencies for the project as a whole. The 'cabal.project.local' file persists across 'clean' but is overwritten on the next use of the 'configure' command. The intention is that the It is never necessary to use the 'configure' command.

cabal new-configure Usage: cabal new-configure [FLAGS] Adjust how the project is built by setting additional package flags and other flags. The configuration options are written to the 'cabal.project.local' file (or configuration from the 'cabal.project' file (if any). This combination is used as the project configuration for all other commands (such as 'new-build', The new-configure command also checks that the project configuration will work. In particular it checks that there is a consistent set of dependencies for the project as a whole. The 'cabal.project.local' file persists across 'new-clean' but is overwritten on the next use of the 'new-configure' command. The intention is that the It is never necessary to use the 'new-configure' command. It is merely a convenience in cases where you do not want to specify flags to 'new-build' (and other commands) every time and yet do not want to alter the 'cabal.project' persistently.

cabal v2-configure Usage: cabal v2-configure [FLAGS] Adjust how the project is built by setting additional package flags and other flags. The configuration options are written to the 'cabal.project.local' file (or configuration from the 'cabal.project' file (if any). This combination is used as the project configuration for all other commands (such as 'v2-build', The v2-configure command also checks that the project configuration will work. In particular it checks that there is a consistent set of dependencies for the project as a whole. The 'cabal.project.local' file persists across 'v2-clean' but is overwritten on the next use of the 'v2-configure' command. The intention is that the It is never necessary to use the 'v2-configure' command. It is merely a convenience in cases where you do not want to specify flags to 'v2-build' (and other commands) every time and yet do not want to alter the 'cabal.project' persistently. Examples:
  cabal v2-configure --with-compiler ghc-7.10.3
    Adjust the project configuration to use the given compiler
    program and check the resulting configuration works.
  cabal v2-configure
    Reset the local configuration to empty and check the overall
    project configuration works. Note: this command is part of the new project-based system (aka nix-style local builds). These features are currently in beta. Please see http://cabal.readthedocs.io/en/latest/nix-local-build-overview.html for details and advice on what you can expect to work. If you encounter problems please file issues at https://github.com/haskell/cabal/issues and if you have any time to get involved and help with testing, fixing bugs etc then that is very much appreciated.

The available targets are the packages in the project as well as individual components within those packages, including libraries, executables, test-suites or benchmarks. Targets can be specified by name or location. If no target is specified then the default is to build the package in the current directory. Dependencies are built or rebuilt as necessary. Additional configuration flags can be specified on the command line and these extend the project configuration from the 'cabal.project', 'cabal.project.local' and other files.

cabal v2-build Usage: cabal v2-build [TARGETS] [FLAGS] Build one or more targets from within the project. The available targets are the packages in the project as well as individual components within those packages, including libraries, executables, test-suites or benchmarks. Targets can be specified by name or location. If no target is specified then the default is to build the package in the current directory. Dependencies are built or rebuilt as necessary. Additional configuration flags can be specified on the command line and these extend the project configuration from the 'cabal.project', 'cabal.project.local' and other files. Examples:
  cabal v2-build
    Build the package in the current directory or all packages in the project
  cabal v2-build pkgname
    Build the package named pkgname in the project
  cabal v2-build ./pkgfoo
    Build the package in the ./pkgfoo directory
  cabal v2-build cname
    Build the component named cname in the project
  cabal v2-build cname --enable-profiling
    Build the component in profiling mode (including dependencies as needed) Note: this command is part of the new project-based system (aka nix-style local builds). These features are currently in beta. Please see http://cabal.readthedocs.io/en/latest/nix-local-build-overview.html for details and advice on what you can expect to work.

cabal v2-repl Usage: cabal v2-repl [TARGET] [FLAGS] Open an interactive session for a component within the project. The available targets are the same as for the 'v2-build' command: individual components within packages in the project, including libraries, executables, test-suites or benchmarks. Packages can also be specified in which case the library component in the package will be used, or the (first listed) executable in the package if there is no library. Dependencies are built or rebuilt as necessary. Additional configuration flags can be specified on the command line and these extend the project configuration from the 'cabal.project', 'cabal.project.local' and other files. Examples, open an interactive session:
  cabal v2-repl
    for the default component in the package in the current directory
  cabal v2-repl pkgname
    for the default component in the package named 'pkgname'
  cabal v2-repl ./pkgfoo
    for the default component in the package in the ./pkgfoo directory
  cabal v2-repl cname
    for the component named 'cname'
  cabal v2-repl pkgname:cname
    for the component 'cname' in the package 'pkgname'
  cabal v2-repl --build-depends lens
    add the latest version of the library 'lens' to the default component (or no componentif there is no project present)
  cabal v2-repl --build-depends "lens >= 4.15 && < 4.18"
    add a version (constrained between 4.15 and 4.18) of the library 'lens' to the default component (or no component if there is no project present) Note: this command is part of the new project-based system (aka nix-style local builds). These features are currently in beta. Please see http://cabal.readthedocs.io/en/latest/nix-local-build-overview.html for details and advice on what you can expect to work. If you encounter problems please file issues at https://github.com/haskell/cabal/issues and if you have any time to get involved and help with testing, fixing bugs etc then that is very much appreciated.

cabal v2-freeze Usage: cabal v2-freeze [FLAGS] The project configuration is frozen so that it will be reproducible in future. The precise dependency configuration for the project is written to the specified). This file extends the configuration from the 'cabal.project' file and thus is used as the project configuration for all other commands (such as The freeze file can be kept in source control. To make small adjustments it may be edited manually, or to make bigger changes you may wish to delete the file and re-freeze. For more control, one approach is to try variations using once you have a satisfactory solution to freeze it using the 'v2-freeze' command with the same set of flags. Examples:
  cabal v2-freeze
    Freeze the configuration of the current project
  cabal v2-build --dry-run --constraint="aeson < 1"
    Check what a solution with the given constraints would look like
  cabal v2-freeze --constraint="aeson < 1"
    Freeze a solution using the given constraints Note: this command is part of the new project-based system (aka nix-style local builds). These features are currently in beta. Please see http://cabal.readthedocs.io/en/latest/nix-local-build-overview.html for details and advice on what you can expect to work.

cabal v2-haddock Usage: cabal v2-haddock [FLAGS] TARGET Build Haddock documentation for the specified packages within the project. Any package in the project can be specified. If no package is specified, the default is to build the documentation for the package in the current directory. The default behaviour is to build documentation for the exposed modules of the library component (if any). This can be changed with the Currently, documentation for dependencies is NOT built. This behavior may change in future. Additional configuration flags can be specified on the command line and these extend the project configuration from the 'cabal.project', Examples:
  cabal v2-haddock pkgname Build documentation for the package named pkgname Note: this command is part of the new project-based system (aka nix-style local builds). These features are currently in beta. Please see http://cabal.readthedocs.io/en/latest/nix-local-build-overview.html for details and advice on what you can expect to work.
