type Arg = String
hWrite :: Handle -> String -> IO ()
writeFile for Handles
mkUnique :: IO FilePath
Get a new temp file, unique from those in /tmp, and from those modules already loaded. Very nice for merge/eval uses.
Will run for a long time if we can't create a temp file, luckily mkstemps gives us a pretty big search space
hMkUnique :: IO (FilePath, Handle)
mkUniqueIn :: FilePath -> IO FilePath
hMkUniqueIn :: FilePath -> IO (FilePath, Handle)
findFile :: [String] -> FilePath -> IO (Maybe FilePath)
mkTemp :: IO (String, Handle)
mkstemps.
We use the Haskell version now... it is faster than calling into mkstemps(3).
create a new temp file, returning name and handle. bit like the mktemp shell utility
mkTempIn :: String -> IO (String, Handle)
replaceSuffix :: FilePath -> String -> FilePath
return the object file, given the .conf file i.e. homedonsfoo.rc -> homedonsfoo.o
we depend on the suffix we are given having a lead .
outFilePath :: FilePath -> [Arg] -> (FilePath, FilePath)
dropSuffix :: FilePath -> FilePath
mkModid :: String -> String
work out the mod name from a filepath
Arguments
| :: FilePath | The path information to modify. |
| -> String | The new extension (without a leading period). Specify an empty string to remove an existing extension from path. |
| -> FilePath | A string containing the modified path information. |
Changes the extension of a file path.
joinFileExt :: String -> String -> FilePath
The joinFileExt function is the opposite of splitFileExt.
It joins a file name and an extension to form a complete file path.
The general rule is:
filename `joinFileExt` ext == path
where
(filename,ext) = splitFileExt path
splitFileExt :: FilePath -> (String, String)
Split the path into file name and extension. If the file doesn't have extension, the function will return empty string. The extension doesn't include a leading period.
Examples:
splitFileExt "foo.ext" == ("foo", "ext")
splitFileExt "foo" == ("foo", "")
splitFileExt "." == (".", "")
splitFileExt ".." == ("..", "")
splitFileExt "foo.bar."== ("foo.bar.", "")
isSublistOf :: Eq a => [a] -> [a] -> Bool
dirname :: FilePath -> FilePath
dirname : return the directory portion of a file path if null, return .
basename :: FilePath -> FilePath
basename : return the filename portion of a path
newer :: FilePath -> FilePath -> IO Bool
is file1 newer than file2?
needs some fixing to work with 6.0.x series. (is this true?)
fileExist still seems to throw exceptions on some platforms: ia64 in particular.
invarient : we already assume the first file, a, exists
encode :: String -> EncodedString
decode :: EncodedString -> String
type EncodedString = String
return the Z-Encoding of the string.
Stolen from GHC. Use -package ghc as soon as possible
panic :: String -> IO a
useful
