ghc-package.eclass
Name
ghc-package.eclass -- This eclass helps with the Glasgow Haskell Compiler's package configuration utility.
Functions
- ghc-getghc
-
returns the name of the ghc executable
- ghc-getghcpkgbin
-
returns the name of the ghc-pkg binary (ghc-pkg itself usually is a shell script, and we have to bypass the script under certain circumstances); for Cabal, we add an empty global package config file, because for some reason the global package file must be specified
- ghc-version
-
returns upstream version of ghc as reported by '--numeric-version' Examples: "7.10.2", "7.9.20141222"
- ghc-pm-version
-
returns package manager(PM) version of ghc as reported by '$(best_version)' Examples: "PM:7.10.2", "PM:7.10.2_rc1", "PM:7.8.4-r4"
- ghc-cabal-version
-
return version of the Cabal library bundled with ghc
- ghc-is-dynamic
-
checks if ghc is built against dynamic libraries binaries linked against GHC library (and using plugin loading) have to be linked the same way:
Note:Unexpected indentation.
- ghc-supports-shared-libraries
-
checks if ghc is built with support for building shared libraries (aka '-dynamic' option)
- ghc-supports-threaded-runtime
-
checks if ghc is built with support for threaded runtime (aka '-threaded' option)
- ghc-supports-smp
-
checks if ghc is built with support for multiple cores runtime
- ghc-supports-interpreter
-
checks if ghc has interpreter mode (aka GHCi) It usually means that ghc supports for template haskell.
- ghc-supports-parallel-make
-
checks if ghc has support for '--make -j' mode The option was introduced in ghc-7.8-rc1.
- ghc-extract-pm-version
-
extract the version of a portage-installed package
- ghc-libdir
-
returns the library directory
- ghc-make-args
-
Returns default arguments passed along 'ghc --make' build mode. Used mainly to enable parallel build mode.
- ghc-confdir
-
returns the (Gentoo) library configuration directory, we store here a hint for 'haskell-updater' about packages installed for old ghc versions and current ones.
- ghc-package-db
-
returns the global package database directory
- ghc-localpkgconfd
-
returns the name of the local (package-specific) package configuration file
- ghc-package-exists
-
tests if a ghc package exists
- check-for-collisions
-
makes sure no packages have the same version as initial package setup
- ghc-install-pkg
-
moves the local (package-specific) package configuration file to its final destination
- ghc-recache-db
-
updates 'package.cache' binary cacne for registered '*.conf' packages
- ghc-register-pkg
-
registers all packages in the local (package-specific) package configuration file
- ghc-reregister
-
re-adds all available .conf files to the global package conf file, to be used on a ghc reinstallation
- ghc-unregister-pkg
-
unregisters a package configuration file
- ghc-pkgdeps
-
exported function: loads a package dependency in a form cabal_package version
- ghc-package_pkg_postinst
-
updates package.cache after package install
- ghc-package_pkg_prerm
-
updates package.cache after package deinstall
- ghc-package_pkg_postrm
-
