1. readFile :: FilePath -> IO String

   base	Prelude

   The readFile function reads a file and returns the contents of the file as a string. The file is read lazily, on demand, as with getContents.

2. readFile :: FilePath -> IO String

   base	System.IO

   The readFile function reads a file and returns the contents of the file as a string. The file is read lazily, on demand, as with getContents.

3. readFile :: FilePath -> IO ByteString

   bytestring	Data.ByteString

   Read an entire file strictly into a ByteString.

4. readFile :: FilePath -> IO ByteString

   bytestring	Data.ByteString.Char8

   Read an entire file strictly into a ByteString.

5. readFile :: FilePath -> IO ByteString

   bytestring	Data.ByteString.Lazy

   Read an entire file lazily into a ByteString. The Handle will be held open until EOF is encountered. Note that this function's implementation relies on hGetContents. The reader is advised to read its documentation.

6. readFile :: FilePath -> IO ByteString

   bytestring	Data.ByteString.Lazy.Char8

   Read an entire file lazily into a ByteString. The Handle will be held open until EOF is encountered. Note that this function's implementation relies on hGetContents. The reader is advised to read its documentation.

7. readFile :: FilePath -> IO Text

   text	Data.Text.IO

   The readFile function reads a file and returns the contents of the file as a string. The entire file is read strictly, as with getContents. Beware that this function (similarly to readFile) is locale-dependent. Unexpected system locale may cause your application to read corrupted data or throw runtime exceptions about "invalid argument (invalid byte sequence)" or "invalid argument (invalid character)". This is also slow, because GHC first converts an entire input to UTF-32, which is afterwards converted to UTF-8. If your data is UTF-8, using decodeUtf8 . readFile is a much faster and safer alternative.

8. readFile :: FilePath -> IO Text

   text	Data.Text.Lazy.IO

   Read a file and return its contents as a string. The file is read lazily, as with getContents. Beware that this function (similarly to readFile) is locale-dependent. Unexpected system locale may cause your application to read corrupted data or throw runtime exceptions about "invalid argument (invalid byte sequence)" or "invalid argument (invalid character)". This is also slow, because GHC first converts an entire input to UTF-32, which is afterwards converted to UTF-8. If your data is UTF-8, using decodeUtf8 . readFile is a much faster and safer alternative.

9. readFile :: FilePath -> IO String

   amazonka-core	Amazonka.Prelude

   The readFile function reads a file and returns the contents of the file as a string. The file is read lazily, on demand, as with getContents.

10. readFile :: FilePath -> IO String

    hedgehog	Hedgehog.Internal.Prelude

    The readFile function reads a file and returns the contents of the file as a string. The file is read lazily, on demand, as with getContents.
