One of the many great reasons to attend the Tcl conference is the
tutorials presented by renowned leaders and experts in the Tcl
community. They will be sharing with you their knowledge of Tcl/Tk
and its extensions, and experience in developing large, versatile and
robust applications - information and techniques which will assist you
in your day-to-day Tcl programming needs.
TclHttpd
( Gerald Lester ) |
The TclHttpd server is one of the big secrets in the HTTP world. It's
stable, extensible, easily embedded in hardware or software, and
includes a set of facilities other http servers don't have. Gerald Lester
explains how to get the most out of a very versatile package.

|
Using Tcllib
( Gerald Lester ) |
There is a wealth of well documented and tested
tools available in the tcllib library.
Gerald will show you how to speed your application development by
finding and using these prebuilt tools.

Advanced Tcl: Namespaces and Packages
( Clif Flynt ) |
This session will describe how to modularize your scripts from simple
procedures and the source command to using namespaces and packages as
well as using upvar and uplevel to control access to data.
The class will also cover techniques for separating GUI code from
business-rule code including using the bind command and variable tracing,
to bind actions to events. Examples include a Tower of Hanoi game
and a Nuclear Reactor simulator.

Starkits
( Steve Landers ) |
A Starkit is a single file packaging of Tcl scripts, platform specific
compiled code and application data; designed to facilitate simple
deployment of cross-platform applications. Tclkit (itself a Starkit) is
a single file Tcl/Tk interpreter used to run Starkits. It also includes
the Metakit database and the [Incr Tcl] object oriented Tcl extension
and, with versions available for over 30 platforms from PDAs to
mainframes, Tclkit is one of the easiest ways of installing Tcl/Tk. A
Starkit may be combined with a specific Tclkit version to create a
self-contained single file application, providing an
"installation-free" deployment model for even the most complicated
Tcl/Tk applications.
This session will describe how to assemble Starkits and Starpacks and,
by example, discuss applications such as the Tcl web server and Wikit
(the wiki implementation behind the Tcler's Wiki). It will show how to
use compressed versions of Tclkit on specific platforms - showing the
development of a stand-alone web application (including web server)
that fits on a single floppy disk. The session will also look at some
advanced topics such as incorporating compiled code for multiple
platforms into Starkits, and the use of the new Starsync facility to
update Starkits from a repository.

MetaKit Database Engine
( Steve Landers ) |
Ever wanted to use advanced database features like join, project in
Tcl? What about changing schemas on the fly - all scripted and with no
database server necessary? The good news is that you can - using the
new oomk interface to Metakit.
The Metakit database is a small, efficient embedded library that fills
the gap between flat-file, relational, object-oriented, and
tree-structured databases. It supports advanced features such as
relational joins, serialization, nested structures, and instant schema
evolution. Metakit works well for moderate-size (a hundred Mb)
datasets, and offers good performance well beyond that size when its
column-wise data model is fully taken advantage of.
Metakit is included in Tclkit and ActiveState's TclDevKit - and so is
already available in the most popular Tcl/Tk distributions.
This tutorial covers the basic metakit concepts (including column-wise
storage and dynamic schema evolution), but also introduces the
advanced features of Metakit, newly available to Tcl programmers via
the oomk extension. These features include:
- relational operators like project, select, join and groupby
- hierarchical operations involving subviews
- set operators like concat, different, intersect, minus, product, union
- hashed and indexed access for performance
- blocked access for scalability

Tcl C API: Embedding and Extending Tcl
( Clif Flynt ) |
This exciting half day course will describe how to build extensions,
and how to embed the Tcl interpreter into a "C" program.
Topics covered include the basic extension
architecture, adding a new command to Tcl, moving data from Tcl script
to C and back, passing status information back to a script, using the
Tcl hash table, creating commands with subcommands, parsing options and
packaging an extension to allow it to be loaded with
package require.
creating and initializing a Tcl interpreter within
another application, reading configuration files, generating a Tk GUI from
within "C" code, and extending application behavior with user scripting.

SQLlite: Tcl API
( D. Richard Hipp ) |
Have you ever needed an SQL database at your disposal without
an SQL Database Server?
SQLlite is a a self-contained, embeddable, zero-configuration SQL
database engine. It supports uses a single file for the database,
and supports ACID transactions, rollback, and most of the SQL-92
syntax.
Richard Hipp describes how to use the Tcl bindings to SQLite to build
applications with complex data requirements.

SQLlite: C API and Internals
( D. Richard Hipp ) |
SQLite is a powerful in the hands of a novice.
Knowing what's under the hood makes it even more powerful.
Richard Hipp explains how SQLite works, and how to use its power
more effectively.

Advanced Tk: GUI appearance
( Jeff Hobbs ) |
There's a big difference between a quick and dirty GUI and a
good looking professional GUI. Jeff will explain the newer features
Tk has added to create a solid GUI you can be proud to send to a
customer, including:
- Controlling the toplevel
- Themed widgets (tile/ttk)
- 8.5 widget enhancements
- Subtle platform differences
