This package utilizes the zlib functions in Tcl 8.6 to build zip archives.


::zipfile::mkzip::mkzip zipfile ?-zipkit? ?-runtime prefix? ?-comment string? ?-directory rootpath? ?-exclude exclude? ?--? ?path...?

This command constructs a zip archive from a directory tree using nothing but Tcl 8.6 core features. The resulting zip file should be compatible with other zip programs - with the possible exception of unicode support. The files generated by this command use utf-8 encoding for all filenames and comments and it has been noticed particularly on Windows the info-zip and the Windows built-in zip view have rather poor support for this part of the ZIP file specification. The 7-Zip program does correctly display utf8 filenames however and the vfs::zip package will use these of course.

If you use

::mkzip::mkzip -zipkit -directory mystuff.vfs
it will pack your "mystuff.vfs/" virtual filesystem tree into a zip archive with a suitable header such that on unix you may mark it executable and it should run with tclkit. Or you can run it with tclsh or wish 8.6 if you like.

To change the executable header, specify the -runtime "preface" where preface is a file containing code you want prefixed. For instance, on Windows you can create a self-extracting zip archive using

mkzip mystuff.exe -directory mystuff.vfs -runtime unzipsfx.exe
The "unzipsfx.exe" is the Info-Zip self-extracting stub.

Accepted options:

-runtime path
This option specifies a file to use as prefix to the actual zip archive. If specified -zipkit will be ignored.
Instructs the command to generate a prefix which makes the archive a zip-based starkit. Ignored if -runtime is present.
-comment string
This options specifies a global comment to place into the generated archive.
-directory path
This option specifies the directory to place into the generated archive. If specified any argument paths are ignored.
-exclude list
This option specifies a list of glob patterns. All paths matching at least one of the patterns are not placed into the generated archive. This option defaults to
    CVS/* */CVS/* *~ ".#*" "*/.#*"
This option signals the end of the options, forcing processing of all further words as arguments, even if they begin with a dash character.

Accepted arguments:

path path
Each path is a directory or file to place into the generated archive. Note however that these will be ignored when option -directory is specified.
