Distribution.Simple
Description
This is the command line front end to the Simple build system. When given the parsed command-line args and package information, is able to perform basic commands like configure, build, install, register, etc.
This module exports the main functions that Setup.hs scripts use. It
re-exports the UserHooks type, the standard entry points like
defaultMain and defaultMainWithHooks and the predefined sets of
UserHooks that custom Setup.hs scripts can extend to add their own
behaviour.
This module isn't called "Simple" because it's simple. Far from it. It's called "Simple" because it does complicated things to simple software.
The original idea was that there could be different build systems that all presented the same compatible command line interfaces. There is still a Distribution.Make system but in practice no packages use it.

parseCompilerFlavorCompat :: ReadP r CompilerFlavor Source #
Like classifyCompilerFlavor but compatible with the old ReadS parser.
It is compatible in the sense that it accepts only the same strings,
eg GHC but not "ghc". However other strings get mapped to OtherCompiler.
The point of this is that we do not allow extra valid values that would
upset older Cabal versions that had a stricter parser however we cope with
new values more gracefully so that we'll be able to introduce new value in
future without breaking things so much.
defaultCompilerFlavor :: Maybe CompilerFlavor Source #
The default compiler flavour to pick when compiling stuff. This defaults to the compiler used to build the Cabal lib.
However if it's not a recognised compiler then it's Nothing and the user
will have to specify which compiler they want.
abiTagString :: AbiTag -> String Source #
unknownCompilerInfo :: CompilerId -> AbiTag -> CompilerInfo Source #
Make a CompilerInfo of which only the known information is its CompilerId, its AbiTag and that it does not claim to be compatible with other compiler id's.
data ProfDetailLevel Source #
Some compilers (notably GHC) support profiling and can instrument programs so the system can account costs to different functions. There are different levels of detail that can be used for this accounting. For compilers that do not support this notion or the particular detail levels, this is either ignored or just capped to some similar level they do support.

type PackageDBStack = [PackageDB] Source #
We typically get packages from several databases, and stack them together. This type lets us be explicit about that stacking. For example typical stacks include:
[GlobalPackageDB] [GlobalPackageDB, UserPackageDB] [GlobalPackageDB, SpecificPackageDB "package.conf.inplace"]
Note that the GlobalPackageDB is invariably at the bottom since it
contains the rts, base and other special compiler-specific packages.
We are not restricted to using just the above combinations. In particular we can use several custom package dbs and the user package db together.
When it comes to writing, the top most (last) package is used.
Some compilers have a notion of a database of available packages. For some there is just one global db of packages, other compilers support a per-user or an arbitrary db specified at some location in the file system. This can be used to build isloated environments of packages, for example to build a collection of related packages without installing them globally.

showCompilerId :: Compiler -> String Source #
compilerVersion :: Compiler -> Version Source #
compilerCompatFlavor :: CompilerFlavor -> Compiler -> Bool Source #
Is this compiler compatible with the compiler flavour we're interested in?
For example this checks if the compiler is actually GHC or is another compiler that claims to be compatible with some version of GHC, e.g. GHCJS.
if compilerCompatFlavor GHC compiler then ... else ...
compilerCompatVersion :: CompilerFlavor -> Compiler -> Maybe Version Source #
Is this compiler compatible with the compiler flavour we're interested in, and if so what version does it claim to be compatible with.
For example this checks if the compiler is actually GHC-7.x or is another compiler that claims to be compatible with some GHC-7.x version.
case compilerCompatVersion GHC compiler of Just (Version (7:_)) -> ... _ -> ...

Simple interface
defaultMain :: IO () Source #
A simple implementation of main for a Cabal setup script.
It reads the package description file using IO, and performs the
action specified on the command line.
defaultMainNoRead :: GenericPackageDescription -> IO () Source #
Like defaultMain, but accepts the package description as input
rather than using IO to read it.
defaultMainArgs :: [String] -> IO () Source #
A version of defaultMain that is passed the command line
arguments, rather than getting them from the environment.
Customization
Hooks allow authors to add specific functionality before and after a command is run, and also to specify additional preprocessors.
- WARNING: The hooks interface is under rather constant flux as we try to understand users needs. Setup files that depend on this interface may break in future releases.

defaultMainWithHooks :: UserHooks -> IO () Source #

line arguments.
defaultMainWithHooksNoRead :: UserHooks -> GenericPackageDescription -> IO () Source #
A customizable version of defaultMainNoRead.
defaultMainWithHooksNoReadArgs :: UserHooks -> GenericPackageDescription -> [String] -> IO () Source #

Standard sets of hooks
simpleUserHooks :: UserHooks Source #
Hooks that correspond to a plain instantiation of the "simple" build system
defaultUserHooks :: UserHooks Source #
Deprecated: Use simpleUserHooks or autoconfUserHooks, unless you need Cabal-1.2 compatibility in which case you must stick with defaultUserHooks
Basic autoconf UserHooks:
postConfruns./configure, if present.- the pre-hooks
preBuild,preClean,preCopy,preInst,preRegandpreUnregread additional build information from package.buildinfo, if present.
Thus configure can use local system information to generate
package.buildinfo and possibly other files.
emptyUserHooks :: UserHooks Source #
Empty UserHooks which do nothing.
