.\" The -*- nroff -*- definitions below are for supplemental macros used
.\" in Tcl/Tk manual entries.
.\"
.\" .AP type name in/out ?indent?
.\"	Start paragraph describing an argument to a library procedure.
.\"	type is type of argument (int, etc.), in/out is either "in", "out",
.\"	or "in/out" to describe whether procedure reads or modifies arg,
.\"	and indent is equivalent to second arg of .IP (shouldn't ever be
.\"	needed;  use .AS below instead)
.\"
.\" .AS ?type? ?name?
.\"	Give maximum sizes of arguments for setting tab stops.  Type and
.\"	name are examples of largest possible arguments that will be passed
.\"	to .AP later.  If args are omitted, default tab stops are used.
.\"
.\" .BS
.\"	Start box enclosure.  From here until next .BE, everything will be
.\"	enclosed in one large box.
.\"
.\" .BE
.\"	End of box enclosure.
.\"
.\" .CS
.\"	Begin code excerpt.
.\"
.\" .CE
.\"	End code excerpt.
.\"
.\" .VS ?version? ?br?
.\"	Begin vertical sidebar, for use in marking newly-changed parts
.\"	of man pages.  The first argument is ignored and used for recording
.\"	the version when the .VS was added, so that the sidebars can be
.\"	found and removed when they reach a certain age.  If another argument
.\"	is present, then a line break is forced before starting the sidebar.
.\"
.\" .VE
.\"	End of vertical sidebar.
.\"
.\" .DS
.\"	Begin an indented unfilled display.
.\"
.\" .DE
.\"	End of indented unfilled display.
.\"
.\" .SO ?manpage?
.\"	Start of list of standard options for a Tk widget. The manpage
.\"	argument defines where to look up the standard options; if
.\"	omitted, defaults to "options". The options follow on successive
.\"	lines, in three columns separated by tabs.
.\"
.\" .SE
.\"	End of list of standard options for a Tk widget.
.\"
.\" .OP cmdName dbName dbClass
.\"	Start of description of a specific option.  cmdName gives the
.\"	option's name as specified in the class command, dbName gives
.\"	the option's name in the option database, and dbClass gives
.\"	the option's class in the option database.
.\"
.\" .UL arg1 arg2
.\"	Print arg1 underlined, then print arg2 normally.
.\"
.\" .QW arg1 ?arg2?
.\"	Print arg1 in quotes, then arg2 normally (for trailing punctuation).
.\"
.\" .PQ arg1 ?arg2?
.\"	Print an open parenthesis, arg1 in quotes, then arg2 normally
.\"	(for trailing punctuation) and then a closing parenthesis.

.SH DESCRIPTION
.PP
This package provides a class for the generation of zip archives\&.
.SH "CLASS API"
.TP
\fB::zipfile::encode\fR ?\fIobjectName\fR?
The class command constructs encoder instances, i\&.e\&. objects\&. The
result of the command is the fully-qualified name of the instance
command\&.
.sp
If no \fIobjectName\fR is specified the class will generate and use an
automatic name\&. If the \fIobjectName\fR was specified, but is not
fully qualified the command will be created in the current namespace\&.
.PP
.SH "INSTANCE API"
.TP
\fB<encoder>\fR \fBcomment:\fR \fItext\fR
This method specifies the text of the global comment for the archive\&.
The result of the method is the empty string\&.
In case of multiple calls to this method for the same encoder the data
from the last call prevails over all previous texts\&.
.TP
\fB<encoder>\fR \fBfile:\fR \fIdst\fR \fIowned\fR \fIsrc\fR ?\fInoCompress\fR?
This method adds a new file to the archive\&.
The contents of the file are found in the filesystem at \fIsrc\fR, and
will be stored in the archive under path \fIdst\fR\&.
If the file is declared as \fIowned\fR by the archive the original
file will be deleted when the archive is constructed and written\&.
If \fInoCompress\fR is set to \fBtrue\fR the file will not be
compressed on writing\&. Otherwise (the default) the file is compressed
if it is advantageous\&.
The result of the method is an empty string\&.
.TP
\fB<encoder>\fR \fBwrite\fR \fIarchive\fR
This method takes the global comment and all added files, encodes them
as a zip archive and stores the result at path \fIarchive\fR in the
filesystem\&.
All added files which were owned by the archive are deleted at this
point\&.
On the issue of ordering, the files are added to the archive in the
same order as they were specified via \fBfile:\fR\&. \fINote\fR that
this behaviour is new for version 0\&.4 and higher\&. Before 0\&.4 no
specific order was documented\&. It was lexicographically sorted\&. The
change was made to support \fBzip\fR-based file formats which require
a specific order of files in the archive, for example "\fI\&.epub\fR"\&.
.PP
.SH "BUGS, IDEAS, FEEDBACK"
This document, and the package it describes, will undoubtedly contain
bugs and other problems\&.
Please report such in the category \fIzipfile\fR of the
\fITcllib Trackers\fR [http://core\&.tcl\&.tk/tcllib/reportlist]\&.
Please also report any ideas for enhancements you may have for either
package and/or documentation\&.
.PP
When proposing code changes, please provide \fIunified diffs\fR,
i\&.e the output of \fBdiff -u\fR\&.
.PP
Note further that \fIattachments\fR are strongly preferred over
inlined patches\&. Attachments can be made by going to the \fBEdit\fR
form of the ticket immediately after its creation, and then using the
left-most button in the secondary navigation bar\&.
