Synopsis

Cradle

data Cradle Source

The environment where this library is used.

Constructors

Cradle
Fields cradleCurrentDir :: FilePath The directory where this library is executed. cradleCabalDir :: Maybe FilePath The directory where a cabal file is found. cradleCabalFile :: Maybe FilePath The file name of the found cabal file. cradlePackageDbOpts :: [GHCOption] The package db options. (["-no-user-package-db","-package-db","/foo/bar/i386-osx-ghc-7.6.3-packages.conf.d"])

Instances

Eq Cradle
Show Cradle

findCradle :: IO Cradle Source

Finding Cradle. Find a cabal file by tracing ancestor directories. Find a sandbox according to a cabal sandbox config in a cabal directory.

Options

data Options Source

Constructors

Options
Fields outputStyle :: OutputStyle hlintOpts :: [String] ghcOpts :: [String] operators :: Bool If `True`, `browse` also returns operators. detailed :: Bool If `True`, `browse` also returns types. expandSplice :: Bool Whether or not Template Haskell should be expanded. lineSeparator :: LineSeparator Line separator string.

newtype LineSeparator Source

The type for line separator. Historically, a Null string is used.

Constructors

LineSeparator String

data OutputStyle Source

Output style.

Constructors

LispStyle	S expression style.
PlainStyle	Plain textstyle.

defaultOptions :: Options Source

A default Options.

Types

type ModuleString = String Source

Module name.

type Expression = String Source

Haskell expression.

`IO` utilities

browseModule Source

Arguments

:: Options
-> Cradle
-> ModuleString	A module name. (e.g. "Data.List")
-> IO String

Getting functions, classes, etc from a module. If detailed is True, their types are also obtained. If operators is True, operators are also returned.

checkSyntax Source

Arguments

:: Options
-> Cradle
-> [FilePath]	The target files.
-> IO String

Checking syntax of a target file using GHC. Warnings and errors are returned.

lintSyntax Source

Arguments

:: Options
-> FilePath	A target file.
-> IO String

Checking syntax of a target file using hlint. Warnings and errors are returned.

infoExpr Source

Arguments

:: Options
-> Cradle
-> FilePath	A target file.
-> ModuleString	A module name.
-> Expression	A Haskell expression.
-> IO String

Obtaining information of a target expression. (GHCi's info:)

typeExpr Source

Arguments

:: Options
-> Cradle
-> FilePath	A target file.
-> ModuleString	A odule name.
-> Int	Line number.
-> Int	Column number.
-> IO String

Obtaining type of a target expression. (GHCi's type:)

listModules :: Options -> Cradle -> IO String Source

Listing installed modules.

listLanguages :: Options -> IO String Source

Listing language extensions.

listFlags :: Options -> IO String Source

Listing GHC flags. (e.g -fno-warn-orphans)

debugInfo Source

Arguments

:: Options
-> Cradle
-> FilePath	A target file.
-> IO String

Obtaining debug information.

Converting the `Ghc` monad to the `IO` monad

withGHC Source

Arguments

:: Alternative m
=> FilePath	A target file displayed in an error message.
-> Ghc (m a)	`Ghc` actions created by the Ghc utilities.
-> IO (m a)

Converting the Ghc monad to the IO monad.

withGHCDummyFile Source

Arguments

:: Alternative m
=> Ghc (m a)	`Ghc` actions created by the Ghc utilities.
-> IO (m a)

Converting the Ghc monad to the IO monad.

`Ghc` utilities

browse Source

Arguments

:: Options
-> Cradle
-> ModuleString	A module name. (e.g. "Data.List")
-> Ghc [String]

Getting functions, classes, etc from a module. If detailed is True, their types are also obtained. If operators is True, operators are also returned.
