mkUnique :: IO FilePath Source #
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
mkTemp :: IO (String, Handle) Source #
create a new temp file, returning name and handle. bit like the mktemp shell utility
replaceSuffix :: FilePath -> String -> FilePath Source #
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 .
dropSuffix :: FilePath -> FilePath Source #
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 Source #
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 pathsplitFileExt :: FilePath -> (String, String) Source #
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 Source #
dirname :: FilePath -> FilePath Source #
dirname : return the directory portion of a file path if null, return "."
newer :: FilePath -> FilePath -> IO Bool Source #
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 Source #
decode :: EncodedString -> String Source #
type EncodedString = String Source #
return the Z-Encoding of the string.
