(require mzlib/file) | package: compatibility-lib

> NOTE: This library is deprecated; use racket/file, instead.

The mzlib/file library mostly re-exports from scheme/file:

> find-relative-path
> explode-path
> normalize-path
> filename-extension
> file-name-from-path
> path-only
> delete-directory/files
> copy-directory/files
> make-directory*
> make-temporary-file
> get-preference
> put-preferences
> fold-files
> find-files
> pathlist-closure

> procedure (call-with-input-file* file proc [mode]) → any
> file : path-string?
> proc : (input-port? -> any)
> mode : (one-of/c 'text 'binary) = 'binary
> > procedure
> > (call-with-output-file* |  | file |  |  |  |
> > |  | proc |  |  |  |
> > | [ | mode |  |  |  |
> > |  | exists]) |  | → |  | any
> file : path-string?
> proc : (output-port? -> any)
> mode : (one-of/c 'text 'binary) = 'binary
> | exists |  | : |  |
> (one-of/c 'error 'append 'update
> 'replace 'truncate 'truncate/replace)
> |  |  | = |  | 'error

Like call-with-input-fileand call-with-output-file, except that the opened port is closed if control escapes from the body of proc.

> procedure (build-relative-path base sub ...) → (and/c path? relative-path?)
> | base |  | : |  |
> (or/c path-string?
> (one-of/c 'up 'same))
> | sub |  | : |  |
> (or/c (and/c path-string?
> relative-path?)
> (one-of/c 'up 'same))
> procedure (build-absolute-path base sub ...) → (and/c path? absolute-path?)
> | base |  | : |  |
> (or/c (and/c path-string?
> (not/c relative-path?))
> (one-of/c 'up 'same))
> | sub |  | : |  |
> (or/c (and/c path-string?
> (not/c complete-path?))
> (one-of/c 'up 'same))

Like build-path, but with extra constraints to ensure a relative or absolute result.
