Any new TCL programmer that googles around for answers will quickly come across the strange place that is the TCL Wiki. This is a community site for TCL with articles on a huge range of topics ranging from individual commands, concepts, libraries, applications, comparisons with other languages, musings- it seems pretty free form from an outsider perspective.

My experience has been that sometimes this more sprawling, informal format is frustrating, when I want the simple answer to a question and it is buried in discussions posted on the wiki. On the other hand the TCL documentation is quite good and MagicSplat has a documentation index, so the wiki is really a place for learning about peoples experiences or how they solved problems, or links to resources.

For this post I just wanted to point out a few little gems that I have come across on the wiki:

Simple Records is a nice little way to create a struct like feature in TCL.

Thingy is a single line struct system. They refer to it as an OOP system, but it doesn't seem to have any properties I would associate with such a system.

The entire definition is:

proc thingy name {proc $name args "namespace eval $name \$args"}

Which creates a namespace in which to store variables and functions.

Cparser is a small script that constructs an sqlite database from C headers. It does depend on packages called yeti and ylex.

I haven't used this, but its kind of interesting that the entire project is simple enough to post with explaination as a wiki page, and I think its interesting to know about systems for parsing C code.
