When Rooted/Unrooted and File/Dir both are present, Rooted/Unrooted must be outermost constructors and File/Dir as inner. Thus the types File (Rooted a) or Dir (Rooted a) are not allowed but Rooted (Dir a) and Rooted (File a) are allowed.

Quasiquoters.

valuertdir :: QuasiQuoter
#

Generates a Rooted (Dir WindowsPath) type from a quoted literal.

Example1 expression
Path.toString (Path.toPath ([rtdir|/usr|] :: Rooted (Dir PosixPath)))"/usr"
valueurdir :: QuasiQuoter
#

Generates a Unrooted (Dir WindowsPath) type from a quoted literal.

Example1 expression
Path.toString (Path.toPath ([urdir|usr|] :: Unrooted (Dir PosixPath)))"usr"
valuertfile :: QuasiQuoter
#

Generates a Rooted (File WindowsPath) type from a quoted literal.

Example1 expression
Path.toString (Path.toPath ([rtfile|/x.txt|] :: Rooted (File PosixPath)))"/x.txt"
valueurfile :: QuasiQuoter
#

Generates a Unrooted (File WindowsPath) type from a quoted literal.

Example1 expression
Path.toString (Path.toPath ([urfile|x.txt|] :: Unrooted (File PosixPath)))"x.txt"
