''XOTcl Is Not Snit''

[Sarnold] 2005-10-05 -- I am trying to emulate snit with an XOTcl class...

 What : Xoins
 Where : http://sarnold.free.fr/abandon/xoins.zip
 Version : 2006-02-20 v0.5, patchlevel 1
 Description : 
 Xoins is a package emulating snit with the same syntax. A great speed improvement is achieved
 by building types as XOTcl classes. Switching from snit types, widgets and widgetadaptors
 may only require a 'package require xoins', and then renaming 'snit::type' to 'xoins::type',
 widget and widgetadaptor require the same process, maybe more transformations if you are unlucky.

''Has the speed improvement been quantified?  Are there examples?'' - [escargo] 29 Sep 2006.

There are two examples and a snit vs xoins benchmark in the .zip file.
xoins typically is twice faster than snit, and much more for object instanciation.

[schlenk] Is this vs. snit 1 or the Tcl 8.5 using snit 2 (which is much faster in some operations)? And with which XOTcl version did you test.

Here are benchmarks with Tcl 8.4:
   Snit 1.1 vs Xoins (XOTcl 1.4.0 & Tcl 8.4.13)
 Creation and destruction...(using %AUTO%)
  Snit : 896.06 microseconds per iteration
  Xoins : 171.11 microseconds per iteration

  Snit : 889.28 microseconds per iteration
  Xoins : 159.28 microseconds per iteration

The following [Snidgets] work fine with Xoins:

   * [snitScrollWindow]
   * [snitfinddialog]
   * [snitbutton]

See also [itins], [Snit], and of course [XOTcl].
