writeFile for Handles
|
|
|
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

create a new temp file, returning name and handle.
bit like the mktemp shell utility
|
|
|
|
|
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 .

work out the mod name from a filepath

:: 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.

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
|
|
|
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.", "")

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

return the Z-Encoding of the string.
Stolen from GHC. Use -package ghc as soon as possible
