IRK is a Tcl IRC client library. IRK is intended for Tcl programmers that want to use the IRC protocol for communication. It can be used to ease the creation of IRC "bots", to serve as the basis for graphical chat clients, and to allow IRKs to find each other without centralized coordination by meeting on a designated IRC server and channel. This last feature makes it ideal for negotiating the initial contact of P2P programs without requiring a central registry or server.
tkxinput contains Xi, a library that adds Xinput management capabilities to the Tk toolkit, and a utility named calibrate that can be used to test various aspects of the Xinput configuration of an X server. calibrate can be used, as its name implies, as a touchscreen calibration facility.
xmmstcl lets you control XMMS playback, skip, pause, change the playlist, change skins, and do everything else provided by the xmms_remote_* methods, which is almost everything from the standard user interface. It also has some things not available there, such as "XMMS onchange" which lets your Tcl/Tk application know when something happens in the player. The companion "TkPlayer" has samples for the most important functions and will keep XMMS busy by generating random playlists with songs that you haven't heard in a while.
OpenIsis provides a library and tools to access CDS/ISIS databases, which are mostly used for bibliographic data (ISO2709, Z39.50) but also well suited for other catalogues due to the very flexible indexing mechanism. Based on a C library, there are also bindings for Perl and Java (Tcl to come).
[incr Widgets] is an object-oriented mega-widget set which extends Tcl/Tk and is based on [incr Tcl] and [incr Tk]. This set of mega-widgets delivers many new, general purpose widgets like option menus, comboboxes, selection boxes, and various dialogs whose couterparts are found in Motif and Windows. Since [incr Widgets] is based on the [incr Tk] extension, the Tk framework of configuration options, widget commands, and default bindings is maintained. In other words, each [incr Widgets] mega-widget seamlessly blends with the standard Tk widgets. They look, act and feel like Tk widgets. In addition, all [incr Widgets] mega-widgets are object oriented and may themselves be extended, using either inheritance or composition.
XPA Messaging provides seamless communication between Unix programs, including X, Tcl/Tk, and generic select() loops. It provides an easy way for users to communicate with these XPA-enabled programs by executing XPA client commands from a shell. Because XPA works both at the programming level and the shell level, it is a powerful tool for unifying any environment, offering flexibility in choosing the best level at which to access XPA services. A program becomes an XPA-enabled server by defining named points of public access through which data and commands can be exchanged with other client programs (and users). Using standard TCP sockets, XPA supports both single-point and broadcast messaging to and from these servers.
MIB Smithy SDK is a dynamic extension to Tcl/Tk (8.4+) that allows development of custom scripts for controlling SNMP agents, manipulating SMI definitions, doing conversions, and more. It is based on the core of Muonics' MIB Smithy, and the SDK supports SMIv1 and SMIv2, as well as SNMPv1/v2c/v3 with HMAC-SHA-96 and HMAC-MD5-96 authentication and DES/CBC and AES128/CFB privacy. It also provides complete read-write access to all elements of SMI/MIB Module definitions, unlike similar extensions that provide only read access to a limited subset. The SDK allows multiple discrete SMI databases and SNMP sessions, and provides all of the built-in validation and error recovery capabilites of the full product, without the visual MIB development environment.
