A pure-Tcl extension which provides maximum Tcl compatibility

eventloop

after, vwait, update, fileevent

This extension provides a Tcl-compatible event loop.

file

Tcl-compatible file command

glob

package

Package management with the package command

load

oo

Jim OO extension

sqlite3

Interface to sqlite. See Sqlite Extension for more information.

metakit

Interface to metakit. See Metakit Extension for more information.

sdl

SDL bindings for 2D graphics, with SDL_Glx primitives.

Currently experimental, but some GLX primitive are supported. This is an example script:

 package require sdl
   
 set xres 200
 set yres 200
 set s [sdl.screen $xres $yres]
   
 set i 0
 while 1 {
     set x1 [rand $xres]
     set y1 [rand $yres]
     set x2 [rand $xres]
     set y2 [rand $yres]
     set rad [rand 40]
     set r [rand 256]
     set g [rand 256]
     set b [rand 256]
     $s fcircle $x1 $y1 $rad $r $g $b 100
     incr i
     if {$i > 2000} {$s flip}
     if {$i == 3000} exit
 }
