A Tcl repository is a isn't really a repository. This page should be phased out into more appropriate pages.

Description  edit

Policy: If you want to add an extension or an application, simply select the proper category, add the name and a short description and include a link as to where it can be found.

AM: I created this page, 26 September 2006, because I realised that the Wiki is, with all its flaws, disorder and general unstructuredness a wonderful place that everybody can contribute to. It is very easy to add or correct information, the infrastructure to do this is all there. So, this page may not be the best repository the Tcl community can wish for, it is at least an easy one to maintain!

Miscellanea  edit

SYStems mmm ... no. For one we already have the gutter [1] if any work is to be done, I recommend it be done to improve our gutter make it work like debian's apt-get or Perl's CPAN (i.e. work on the command line interface, or the Tk interface ;))

AM: This page is not meant to replace gutter - not at all! It is just that due to the lack of an obvious central repository people can not find what they are looking for. This page is merely meant as a guide.

SYStems: The gutter (if it succeed) should be the Obvious destination to look (and add) for packages & to find information about packages. Plus a single wiki page just isn't practical or pretty. Look at the ask and it shall be give pages, I think they are horrible, a wiki can't replace a forum, a wiki can't replace a package repository either.

I'm rather uncertain what the OP and others want on this page. In the past, there have been, and continue to be, pages with long lists of tcl extensions and applications. Why start yet another one?

I can understand why one might want to have one page listing the various repositories - but why start a parallel page on this wiki for this sort of thing?


Based on my recent rant [?] on comp.lang.tcl, here's a script that implements the sort of thing which I'm really looking for on the client side. Note that it uses a fair number of Tcl 8.5 features; this is deliberate.
package require Tcl 8.5
package require http 2

namespace eval pkgutil {
    namespace export "\[a-z]*"
    namespace ensemble create

    variable repository http://repository.tcl.tk/packages

    proc listPackages {{pattern *}} {
       variable repository
       # We pass the pattern, but the repository MAY ignore it
       set token [http::geturl $repository?[http::formatQuery pat $pattern]]
       if {![string match 2?? [http::ncode $token]]} {
          set msg [join [lrange [split [http::code $token]] 2 end]]
          http::cleanup $token
          return -code error $msg
       set result {}
       foreach pkgName [lsort [split [http::data $token]]] {
          if {[string match $pattern $pkgName]} {
             lappend result $pkgName
       http::cleanup $token
       return $result
    proc listVersions {pkgName {pattern *}} {
       variable repository
       # We pass the pattern, but the repository MAY ignore it
       set token [http::geturl \
             $repository/$pkgName?[http::formatQuery pat $pattern]]
       if {![string match 2?? [http::ncode $token]]} {
          set msg [join [lrange [split [http::code $token]] 2 end]]
          http::cleanup $token
          return -code error $msg
       set result {}
       foreach version [lsort [split [http::data $token]]] {
          if {[string match $pattern $version]} {
             lappend result $version
       http::cleanup $token
       return $result
    proc listPlatforms {pkgName version {pattern *}} {
       variable repository
       # We pass the pattern, but the repository MAY ignore it
       set token [http::geturl \
             $repository/$pkgName/$version?[http::formatQuery pat $pattern]]
       if {![string match 2?? [http::ncode $token]]} {
          set msg [join [lrange [split [http::code $token]] 2 end]]
          http::cleanup $token
          return -code error $msg
       set result {}
       foreach platform [lsort [split [http::data $token]]] {
          if {[string match $pattern $platform]} {
             lappend result $platform
       http::cleanup $token
       return $result
    proc fetch {pkgName version platform {targetFilename ~}} {
       if {[file isdirectory $targetFilename]} {
          set targetFilename [file join $targetFilename $pkgName-$version.tm]
       set out [open $targetFilename wb]
       set url $repository/$pkgName/$version/$platform/$pkgName-$version.tm
       for {set i 0} {$i<5} {incr i} {
          set token [http::geturl $url -binary 1 -channel $out $url]
          if {![string match 3?? [http::ncode $token]]} {
          # Follow redirects a few times (the loop around this)
          set url [dict get [array get $token] meta Location]
          http::cleanup $token
       if {![string match 2?? [http::ncode $token]]} {
          set msg [join [lrange [split [http::code $token]] 2 end]]
          http::cleanup $token
          return -code error $msg
       http::cleanup $token
       close $out

package provide pkgutil 0.1

SC: This sort of functionality has been available in the CANTCL code since the start, eg:
# installer::install_extension --
#   Download a zip file contianing a tcl extension from the given 
#   uri and install it in the current tcl installation.
# Arguments:
#   uri        -- the location of the zip file
# Results:
#   The file is downloaded, installed and the local copy is deleted

This is in the installer package, you can still browse the code via cantcl at http://www.ics.mq.edu.au/~cassidy/cgi-bin/cantcl/package/installer-0.6/tcl along with a bunch of other utilities. The CANTCL package manages the server side of this.
