@title[#:tag "zip"]{@exec{zip} File Creation}
@defmodule[file/zip]{The @racketmodname[file/zip] library provides
utilities to create @exec{zip} archive files, which are compatible
with both Windows and Unix (including Mac OS X) unpacking. The actual
compression is implemented by @racket[deflate].}
@defproc[(zip [zip-file path-string?][path path-string?] ...)
void?]{
Creates @racket[zip-file], which holds the complete content of all
@racket[path]s. The given @racket[path]s are all expected to be
relative path names of existing directories and files (i.e., relative
to the current directory). If a nested path is provided as a
@racket[path], its ancestor directories are also added to the
resulting zip file, up to the current directory (using
@racket[pathlist-closure]). Files are packaged as usual for
@exec{zip} files, including permission bits for both Windows and Unix
(including Mac OS X). The permission bits are determined by
@racket[file-or-directory-permissions], which does not preserve the
distinction between owner/group/other permissions. Also, symbolic
links are always followed.}
@defproc[(zip->output [paths (listof path-string?)]
[out output-port? (current-output-port)])
void?]{
Zips each of the given @racket[paths], and packages it as a zip
``file'' that is written directly to @racket[out]. Unlike
@racket[zip], the specified @racket[paths] are included as-is; if a
directory is specified, its content is not automatically added, and
nested directories are added without parent directories.}
@defboolparam[zip-verbose on?]{
A parameter that controls output during a @racket[zip]
operation. Setting this parameter to a true value causes @racket[zip]
to display to @racket[(current-error-port)] the filename that is
currently being compressed.}
