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.

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

shelly Shelly Shelly.Lifted Shelly.Pipe

A monadic-conditional version of the when guard.

findDirFilterWhen :: (FilePath -> Sh Bool) -> (FilePath -> Sh Bool) -> FilePath -> Sh [FilePath]

shelly Shelly Shelly.Lifted

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

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

shelly Shelly Shelly.Lifted

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