Welcome to my wiki page, where I present some of my Tcl stuff and thoughts.
My miscellaneous Tcl utilities are here and they contain:

along with a lot of small but useful stuff (functional, metric/binary unit conversion, terminal emulator formatting, Lispy stuff, dict and list additions, etc...).
Some Tcl based projects:
Other stuff in separate Wiki pages:
Here are my current thoughts about Tcl itself: https://world-playground-deceit.net/blog/2024/why_tcl.html
And some other, more specific "problems" I identified during my Tcl journey:
Note: mostly inactive as a serious Tcl programmer since I became infatuated with CL; still using it as a scripting language for its superior string handling, nice dictionary API or event loop.
