APWTCL is an acronym '''A'''rnulf's '''P'''referred '''W'''eb '''TCL'''

This version of [APWTCL] is written in [Objective C]

[apw] 2012-05-23:

I wanted to have a light weight version of Tcl which has the same features as [APWTCL] written in [Objective C] to run native on [iOS] iPhones. I wanted to have an easy comparable version to be able to figure out the difference between [APWTCL] in a browser and running [APWTCL] native on the same smart phone. And the positive side effect: I am now familiar with [Objective C], which I did not use before :).

The implementation started mid of April 2012 and is now (2012-05-23) running all my small about 100 tests successful (and additionally the test suite for [wtk], which I have also running for [APWTCL]). The size is a bit bigger than [APWTCL] because of the need for all the setter and getter methods and the header files. It is about 44.000 LOC which is about 30% more code.

One feature I have built in is to instantiate even all (Tcl) core commands and command ensembles on demand when needed (similar to autoloading/unknown handling). Loading is not (yet?) available for iOS. It is only available for MacOS using bundle mechanism.

This version is running under XCode in the iOS 5.1 simulator, test on a real iPhone still to be done.

The base for that implementation is Tcl 8.6 and Itcl 4.0 including a lot of the snit functionality implemented in Itcl 4.0. When running the [wtk] test suite one can see, that the implemented subset of snit is running unmodified using the following lines at the beginning of the script:


======
package require itcl

interp alias {} ::snit::macro {} ::itcl macro
interp alias {} snit::macro {} ::itcl macro
interp alias {} ::snit::type {} ::itcl type
interp alias {} snit::type {} ::itcl type
