:: FilePath -> String -package:turtle -package:easy-file -package:sydtest -package:classy-prelude

Get the extension of a file, returns "" for no extension, .ext otherwise.

takeExtension "/directory/path.ext" == ".ext"
takeExtension x == snd (splitExtension x)
Valid x => takeExtension (addExtension x "ext") == ".ext"
Valid x => takeExtension (replaceExtension x "ext") == ".ext"

Get all extensions.

takeExtensions "/directory/path.ext" == ".ext"
takeExtensions "file.tar.gz" == ".tar.gz"

Get the base name, without an extension or path.

takeBaseName "/directory/file.ext" == "file"
takeBaseName "file/test.txt" == "test"
takeBaseName "dave.ext" == "dave"
takeBaseName "" == ""
takeBaseName "test" == "test"
takeBaseName (addTrailingPathSeparator x) == ""
takeBaseName "file/file.tar.gz" == "file.tar"

Attempt to convert a FilePath to a string suitable for use with functions in System.IO. The contents of this string are platform‐dependent, and are not guaranteed to be human‐readable. For converting FilePaths to a human‐readable format, use toText. Since: 0.3.1

Derive module name from specified path.

Convert a filepath to an URL starting from the site root Example:

toUrl "foo/bar.html"

Result:

"/foo/bar.html"

This also sanitizes the URL, e.g. converting spaces into '%20'

Deprecated: Use id

Get the Haskell module name corresponding to a given .proto file.

File-not-found message.

Cannot-open-file message.

Convert a FilePath to a platform‐specific format, suitable for use with external OS functions. Note: The type platformTextFormat can change depending upon the underlying compilation platform. Consider using toText or encodeString instead. See Rules for more information. Since: 0.3

given a string, return a key that can be used in Indexable instances Of non persistent objects, such are cached objects (it changes fron execution to execution) . It uses addrHash

Show any value This shows any value, as long as it's not unlifted. The result should be equal to show instances, with the following caveats:

• User-defined types (types not explicitly known to this library) with a custom Show instance will still be showable, but the result will be what the derived show instance would have done.
• Record field names are not known at runtime, so they are not shown.
• UNPACKed data is not visible to this library (if you compile with -O0 ghc will not unpack data, so that might be a workaround if necessary).

If classification fails, we show the actual closure.

A specialised variant of showsPrec, using precedence context zero, and returning an ordinary String.
