Arnulf P. Wiedemann

I am living in a little village in the south of Germany near Augsburg (Bavaria)

I have more than 40 years of programming behind me using languages like: Algol60, Pascal, BCPL, CPM-80, C, C++, Icon, Java, Tcl, Go (Golang) and also awk, sed, Javascript, jquery, html5, css, Objective-C, sh-scripts ...

After all the years I like to program in Tcl/Tk

Programming with Tcl/Tk since 1995.

I have been and am using Tcl/Tk and Itcl in commercial applications in the company I am working for, mostly for client server applications (client on windows, server Linux/Unix protocol http using apache server and rivet, with oracle and mysql databases).

At home I am using Tcl/Tk and Itcl for doing a lot of stuff on my computers for example a GUI for administrating my CD's in a mysql database using ID3 tags or making a selection on that database and send that to xmms for playing etc. That was before I found snackamp.

Projects:

• tclurtp the low level part of tcluno [L1 ] an uno interface for OpenOffice.org written in pure Tcl.
• 2018-09-01 I have started getting familiar with golang [L2 ] and Revel [L3 ] as a Web Framework for go. I am enjoying that language a lot (it is also BSD licensed), and additionally as it has some features which look like borrowed from Tcl i.e. associative arrays, very few tokens, a lot of built in functionality and options with suitable default values a lot of very interesting packages etc.

Work in progress:

• 2019-01-01 I am trying to build an interpreter for go based an the base of the Tcl interpreter and using the scanner and parser for go (available as packages) to build an AST (Abstract Syntax Tree) and then interpreting the nodes of the AST.
• 2019-07-01 Start of programming a web based GUI Builder with go and revel.
• itcl-ng a reimplementation of Itcl based on tclOO, trying to make that an extension using only stubs interfaces to the Tcl core. 2008-12-11 beta version released [L4 ]
• ntkWidget a reimplementation of NexTk based on itcl-ng
• tclGL a Tcl wrapper for OpenGL gl* functions generated mostly from GL/gl.h by a Tcl script
• tclGLMWFW a Tcl wrapper for GLFW but with multiple windows
• ToW Tcl on WebFreeWay (called ATWF later on) collecting ideas for a Tcl based web framework. Maybe it will be called TRAX (Tcl's Rapid webAccess eXtension). There are plans to start the implementation as a "fun" project. 2010-03-05: The start of an implementation of such a tool can be found here: [L5 ]
• Reporting Tools with Tcl some tools written with itcl-ng to allow easy building of GUI's for reports to be shown as web pages or in a client
• itclwidgets a reimplementation of Iwidgets using itcl-ng (and Tk) without using itk
• ATWF A Tcl Web Framework written with itcl-ng using a lot of ideas from php Zend Framework
• incr Tcl in Javascript A Tcl/Itcl Implementation in Javascript based on Tcl in Javascript with a lot of enhancements and a lot of Tcl 8.6 functionality
• Tk Widgets in Javascript A Tk widget Implementation in Javascript based on incr Tcl in Javascript using DOM trees
• APWTCL A Tcl Parser in Javascript (similar to incr Tcl in Javascript), which is mostly derived from Jim with additionally namespaces and itcl.
• APWTCL (Java) A Tcl Parser in Java (nearly identical to APWTCL, but implemented in Java).
• APWTCL (Objective C) A Tcl Parser in Objective C (nearly identical to APWTCL, but implemented in Objective C for use on Mac OS and iOS).
• gles2 is a Tcl wrapper package for the OpenGL ES 2.0 library and FreeType fonts.
• ntkThemed is a new implementation of Tk widgets based on OpenGL ES 2.0 and itcl-ng.
• TclGles20 is a Tcl layer forAPWTCL makeing some of the OpenGL ES 2.0 commands available/callable.

GSoC:

• GSoc Idea: Grid Manager and Html Generator
• GSoC Idea: Auto Documentation Tool for Tcl
• GSoC Idea: Tktable for wtk
• GSoc Idea: Testsuite for RAPL
• GSoC Idea: Tcl Plugin for Netbeans done as a project in 2011

Presentations on Tcl conferences:

• ntkWidget at the 7th European Tcl/Tk Users Meeting Conference.
• Reporting Tools with Tcl at the 9th European Tcl/Tk Users Meeting.
• ATWF at the Seventeenth Annual Tcl/Tk Conference (2010).
• incr Tcl in Javascript at the Eighteenth Annual Tcl/Tk Conference (2011).
• Tk Widgets in Javascript at the Eighteenth Annual Tcl/Tk Conference (2011).
• APWTCL at the 10th European Tcl/Tk Users Meeting 2012 .
• WTK for APWTCL at the Nineteenth Annual Tcl/Tk Conference (2012).
• itclWidgets at the 11th European Tcl/Tk User Meeting 2013 .
• ntkThemed at the Twentieth Annual Tcl/Tk Conference (2013) within a WIP session.

Conferences:

• together with Paul Obermeier and Vaclav Snajdr organized the 10th European Tcl/Tk Users Meeting 2012
• together with Paul Obermeier organized the 11th European Tcl/Tk Users Meeting 2013
• together with Paul Obermeier organized the 12th European Tcl/Tk Users Meeting 2014

One evening every month you can find me at TUGM: TUGM Home Page .
