(require mzlib/file)

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

(call-with-input-file* file proc [mode]) → any
file : path-string?
proc : (input-port? -> any)
mode : (one-of/c 'text 'binary) = 'binary

(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.

(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))

(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.
