.SH DESCRIPTION
.PP
The \fBzipfs\fR command (the sole public command provided by the built-in
package with the same name) provides Tcl with the ability to mount the
contents of a ZIP archive file as a virtual file system. ZIP archives support
simple encryption, sufficient to prevent casual inspection of their contents
but not able to prevent access by even a moderately determined attacker.
.TP
\fBzipfs canonical\fR ?\fImountpoint\fR? \fIfilename\fR ?\fIinZipfs\fR?
.
This takes the name of a file, \fIfilename\fR, and produces where it would be
mapped into a zipfs mount as its result. If specified, \fImountpoint\fR says
within which mount the mapping will be done; if omitted, the main root of the
zipfs system is used. The \fIinZipfs\fR argument is a an optional boolean
which controls whether to fully canonicalise the name; it defaults to true.
.TP
\fBzipfs exists\fR \fIfilename\fR
.
Return 1 if the given filename exists in the mounted zipfs and 0 if it does not.
.TP
\fBzipfs find\fR \fIdirectoryName\fR
.
Recursively lists files including and below the directory \fIdirectoryName\fR.
The result list consists of relative path names starting from the given
directory. This command is also used by the \fBzipfs mkzip\fR and \fBzipfs
mkimg\fR commands.
.TP
\fBzipfs info\fR \fIfile\fR
.
Return information about the given \fIfile\fR in the mounted zipfs.  The
information consists of:

filesystem at \fImountpoint\fR.  After this command executes, files contained
in \fIzipfile\fR will appear to Tcl to be regular files at the mount point.
.RS
.PP
With no \fIzipfile\fR, returns the zipfile mounted at \fImountpoint\fR.  With
no \fImountpoint\fR, return all zipfile/mount pairs.  If \fImountpoint\fR is
specified as an empty string, mount on file path.
.PP
\fBNB:\fR because the current working directory is a concept maintained by the
operating system, using \fBcd\fR into a mounted archive will only work in the
current process, and then not entirely consistently (e.g., if a shared library
uses direct access to the OS rather than through Tcl's filesystem API, it will
not see the current directory as being inside the mount and will not be able
to access the files inside the mount).
.RE
.TP
\fBzipfs root\fR
.
Returns a constant string which indicates the mount point for zipfs volumes
for the current platform. On Windows, this value is
.QW \fBzipfs:/\fR .
On Unix, this value is
.QW \fB//zipfs:/\fR .
.RE
.TP
\fBzipfs unmount \fImountpoint\fR
.
Unmounts a previously mounted ZIP archive mounted to \fImountpoint\fR.
.SS "ZIP CREATION COMMANDS"
This package also provides several commands to aid the creation of ZIP
archives as Tcl applications.
.TP




















\fBzipfs mkzip\fR \fIoutfile indir\fR ?\fIstrip\fR? ?\fIpassword\fR?
.
Creates a ZIP archive file named \fIoutfile\fR from the contents of the input
directory \fIindir\fR (contained regular files only) with optional ZIP
password \fIpassword\fR. While processing the files below \fIindir\fR the
optional file name prefix given in \fIstrip\fR is stripped off the beginning
of the respective file name.  When stripping, it is common to remove either
the whole source directory name or the name of its parent directory.
.RS
.PP
\fBCaution:\fR the choice of the \fIindir\fR parameter (less the optional
stripped prefix) determines the later root name of the archive's content.
.RE
.TP
\fBzipfs mkimg\fR \fIoutfile indir\fR ?\fIstrip\fR? ?\fIpassword\fR? ?\fIinfile\fR?
.
Creates an image (potentially a new executable file) similar to \fBzipfs
mkzip\fR; see that command for a description of most parameters to this
command, as they behave identically here.
.RS
.PP
If the \fIinfile\fR parameter is specified, this file is prepended in front of
the ZIP archive, otherwise the file returned by \fBinfo nameofexecutable\fR
(i.e., the executable file of the running process) is used. If the
\fIpassword\fR parameter is not empty, an obfuscated version of that password
(see \fBzipfs mkkey\fR) is placed between the image and ZIP chunks of the
output file and the contents of the ZIP chunk are protected with that
password.
.PP
If there is a file, \fBmain.tcl\fR, in the root directory of the resulting
archive and the image file that the archive is attached to is a \fBtclsh\fR
(or \fBwish\fR) instance (true by default, but depends on your configuration),
then the resulting image is an executable that will \fBsource\fR the script in
that \fBmain.tcl\fR after mounting the ZIP archive, and will \fBexit\fR once
that script has been executed.
.PP
\fBCaution:\fR highly experimental, not usable on Android, only partially
tested on Linux and Windows.
.RE
.TP
\fBzipfs mkkey\fR \fIpassword\fR
.
Given the clear text \fIpassword\fR argument, an obfuscated string version is
returned with the same format used in the \fBzipfs mkimg\fR command.
.TP
\fBzipfs lmkimg\fR \fIoutfile inlist\fR ?\fIpassword infile\fR?
.
This command is like \fBzipfs mkimg\fR, but instead of an input directory,
\fIinlist\fR must be a Tcl list where the odd elements are the names of files
to be copied into the archive in the image, and the even elements are their
respective names within that archive.
.TP
\fBzipfs lmkzip\fR \fIoutfile inlist\fR ?\fIpassword\fR?
.
This command is like \fBzipfs mkzip\fR, but instead of an input directory,
\fIinlist\fR must be a Tcl list where the odd elements are the names of files
to be copied into the archive, and the even elements are their respective
names within that archive.
.SH "EXAMPLES"
.PP
Mounting an ZIP archive as an application directory and running code out of it
before unmounting it again:
.PP
.CS
set zip myApp.zip
set base [file join [\fbzipfs root\fR] myApp]

\fBzipfs mount\fR $base $zip
# $base now has the contents of myApp.zip

source [file join $base app.tcl]
# use the contents, load libraries from it, etc...

\fBzipfs unmount\fR $zip
.CE
.PP
Creating a ZIP archive, given that a directory exists containing the content
to put in the archive. Note that the source directory is given twice, in order
to strip the exterior directory name from each filename in the archive.
.PP
.CS
set sourceDirectory [file normalize myApp]
set targetZip myApp.zip

\fBzipfs mkzip\fR $targetZip $sourceDirectory $sourceDirectory
.CE
.PP
Encryption can be applied to ZIP archives by providing a password when
building the ZIP and when mounting it.
.PP
.CS
set zip myApp.zip
set sourceDir [file normalize myApp]
set password "hunter2"
set base [file join [\fbzipfs root\fR] myApp]

# Create with password
\fBzipfs mkzip\fR $targetZip $sourceDir $sourceDir $password

# Mount with password
\fBzipfs mount\fR $base $zip $password
.CE
.PP
When creating an executable image with a password, the password is placed
within the executable in a shrouded form so that the application can read
files inside the embedded ZIP archive yet casual inspection cannot read it.
.PP
.CS
set appDir [file normalize myApp]
set img "myApp.bin"
set password "hunter2"

# Create some simple content to define a basic application
file mkdir $appDir
set f [open $appDir/main.tcl]
puts $f {
    puts "Hi. This is [info script]"
}
close $f

# Create the executable
\fBzipfs mkimg\fR $img $appDir $appDir $password

# Launch the executable, printing its output to stdout
exec $img >@stdout
#    prints: \fI Hi. This is //zipfs:/app/main.tcl\fR
