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?

The result of the command is a dictionary describing the contents of the archive\&. The structure of this dictionary is not public\&. Proper access should be made through the provided accessor command of this package\&. .TP \fB::zipfile::decode::close\fR This command releases all state associated with the last call of \fB::zipfile::decode::open\fR\&. The result of the command is the empty string\&. .TP \fB::zipfile::decode::comment\fR \fIadict\fR This command takes a dictionary describing the currently open zip archive file, as returned by \fB::zipfile::decode::archive\fR, and returns the global comment of the archive\&. .TP \fB::zipfile::decode::content\fR \fIarchive\fR This is a convenience command which decodes the specified zip \fIarchive\fR file and returns the list of paths found in it as its result\&. .TP \fB::zipfile::decode::copyfile\fR \fIadict\fR \fIpath\fR \fIdst\fR This command takes a dictionary describing the currently open zip archive file, as returned by \fB::zipfile::decode::archive\fR, and copies the decompressed contents of the file \fIpath\fR in the archive to the the file \fIdst\fR\&. An error is thrown if the file is not found in the archive\&. .TP \fB::zipfile::decode::files\fR \fIadict\fR This command takes a dictionary describing the currently open zip archive file, as returned by \fB::zipfile::decode::archive\fR, and returns the list of files found in the archive\&. .TP \fB::zipfile::decode::getfile\fR \fIzdict\fR \fIpath\fR This command takes a dictionary describing the currently open zip archive file, as returned by \fB::zipfile::decode::archive\fR, and returns the decompressed contents of the file \fIpath\fR in the archive\&. An error is thrown if the file is not found in the archive\&. .TP \fB::zipfile::decode::hasfile\fR \fIadict\fR \fIpath\fR This command takes a dictionary describing the currently open zip archive file, as returned by \fB::zipfile::decode::archive\fR, and check if the specified \fIpath\fR is found in the archive\&. The result of the command is a boolean flag, \fBtrue\fR if the path is found, and \fBfalse\fR otherwise\&. .TP \fB::zipfile::decode::iszip\fR \fIarchive\fR This command takes the path of a presumed zip \fIarchive\fR file and returns a boolean flag as the result of the command telling us if it actually is a zip archive (\fBtrue\fR), or not (\fBfalse\fR)\&. .TP \fB::zipfile::decode::open\fR \fIarchive\fR This command takes the path of a zip \fIarchive\fR file and prepares it for decoding\&. The result of the command is the empty string\&. All important information is stored in global state\&. If multiple open calls are made one after the other only the state of the last call is available to the other commands\&. .TP \fB::zipfile::decode::unzip\fR \fIadict\fR \fIdstdir\fR This command takes a dictionary describing the currently open zip archive file, as returned by \fB::zipfile::decode::archive\fR, and unpacks the archive in the given destination directory \fIdstdir\fR\&. The result of the command is the empty string\&. .TP \fB::zipfile::decode::unzipfile\fR \fIarchive\fR \fIdstdir\fR This is a convenience command which unpacks the specified zip \fIarchive\fR file in the given destination directory \fIdstdir\fR\&. .sp The result of the command is the empty string\&. .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\&. .SH KEYWORDS decompression, zip .SH CATEGORY File .SH COPYRIGHT .nf Copyright (c) 2008-2016 Andreas Kupries .fi
