Description

A module for shell-like programming in Haskell. Shelly's focus is entirely on ease of use for those coming from shell scripting. However, it also tries to use modern libraries and techniques to keep things efficient.

The functionality provided by this module is (unlike standard Haskell filesystem functionality) thread-safe: each Sh maintains its own environment and its own working directory.

Recommended usage includes putting the following at the top of your program, otherwise you will likely need either type annotations or type conversions

type StM Sh a

Deprecated: Use Sh instead of ShIO

ShIO is Deprecated in favor of Sh, which is easier to type.

shelly :: MonadIO m => Sh a -> m a Source #

Enter a Sh from (Monad)IO. The environment and working directories are inherited from the current process-wide values. Any subsequent changes in processwide working directory or environment are not reflected in the running Sh.

shellyNoDir :: MonadIO m => Sh a -> m a Source #

Deprecated: Just use shelly. The default settings have changed

Deprecated now, just use shelly, whose default has been changed. Using this entry point does not create a .shelly directory in the case of failure. Instead it logs directly into the standard error stream (stderr).

shellyFailDir :: MonadIO m => Sh a -> m a Source #

Using this entry point creates a .shelly directory in the case of failure where errors are recorded.

Running external commands.

run_ :: MonadSh m => FilePath -> [Text] -> m () Source #

runFoldLines :: MonadSh m => a -> FoldCallback a -> FilePath -> [Text] -> m a Source #

cmd :: ShellCmd result => FilePath -> result Source #

variadic argument version of run. Please see the documenation for run.

The syntax is more convenient, but more importantly it also allows the use of a FilePath as a command argument. So an argument can be a Text or a FilePath without manual conversions. a FilePath is automatically converted to Text with toTextIgnore.

Convenient usage of cmd requires the following:

Utility Functions

whenM :: Monad m => m Bool -> m () -> m () Source #

A monadic-conditional version of the "when" guard.

unlessM :: Monad m => m Bool -> m () -> m () Source #

A monadic-conditional version of the unless guard.

time :: MonadShControl m => m a -> m (Double, a) Source #

sleep :: MonadSh m => Int -> m () Source #

Re-exported for your convenience

liftIO :: MonadIO m => IO a -> m a #

Lift a computation from the IO monad.

when :: Applicative f => Bool -> f () -> f () #

Conditional execution of Applicative expressions. For example,

when debug (putStrLn "Debugging")

will output the string Debugging if the Boolean value debug is True, and otherwise do nothing.

unless :: Applicative f => Bool -> f () -> f () #

The reverse of when.

type FilePath = String #

File and directory names are values of type String, whose precise meaning is operating system dependent. Files can be opened, yielding a handle which can then be used to operate on the contents of that file.

(<$>) :: Functor f => (a -> b) -> f a -> f b infixl 4 #

An infix synonym for fmap.

The name of this operator is an allusion to $. Note the similarities between their types:

 ($)  ::              (a -> b) ->   a ->   b
(<$>) :: Functor f => (a -> b) -> f a -> f b

Whereas $ is function application, <$> is function application lifted over a Functor.

Examples

Expand

Convert from a Maybe Int to a Maybe String using show:

>>> show <$> Nothing
Nothing
>>> show <$> Just 3
Just "3"

Convert from an Either Int Int to an Either Int String using show:

>>> show <$> Left 17
Left 17
>>> show <$> Right 17
Right "17"

Double each element of a list:

>>> (*2) <$> [1,2,3]
[2,4,6]

Apply even to the second element of a pair:

>>> even <$> (2,2)
(2,True)

internal functions for writing extensions

get :: MonadSh m => m State Source #

put :: MonadSh m => State -> m () Source #

find functions

find :: FilePath -> Sh [FilePath] Source #

List directory recursively (like the POSIX utility "find"). listing is relative if the path given is relative. If you want to filter out some results or fold over them you can do that with the returned files. A more efficient approach is to use one of the other find functions.

findWhen :: (FilePath -> Sh Bool) -> FilePath -> Sh [FilePath] Source #

find that filters the found files as it finds. Files must satisfy the given filter to be returned in the result.

findFold :: (a -> FilePath -> Sh a) -> a -> FilePath -> Sh a Source #

Fold an arbitrary folding function over files froma a find. Like findWhen but use a more general fold rather than a filter.

findDirFilter :: (FilePath -> Sh Bool) -> FilePath -> Sh [FilePath] Source #

find that filters out directories as it finds Filtering out directories can make a find much more efficient by avoiding entire trees of files.

findDirFilterWhen Source #

Arguments

:: (FilePath -> Sh Bool)

directory filter

-> (FilePath -> Sh Bool)

file filter

-> FilePath

directory

-> Sh [FilePath] 

similar findWhen, but also filter out directories Alternatively, similar to findDirFilter, but also filter out files Filtering out directories makes the find much more efficient

findFoldDirFilter :: (a -> FilePath -> Sh a) -> a -> (FilePath -> Sh Bool) -> FilePath -> Sh a Source #

like findDirFilterWhen but use a folding function rather than a filter The most general finder: you likely want a more specific one
