The following is a list of extensions available for [Jim].
Note that all the extensions are shipped directly with the core, so you
will find they inside the Jim tar.gz ready to be compiled.

----
'''Ansi I/O'''

Goal: Pure ANSI/C file I/O capabilities, mainly useful for embedded systems or
if you plan to use Jim in context where only an ANSI/C compiler may be assumed
(for example to replace autoconf/automake with a Jim script).

Status: This extension is already usable, while not fully complete (the ''read''
subcommand is missing).

Platforms: tested under POSIX systems and win32.
----
'''Sqlite'''

Goal: To provide sqlite bindings. This extension exports a command-based interface
to access the database (Tk alike), supports [format]-alike auto escape of special chars
in queries, returns rows as lists of [dict]s so you in Jim it is possible to access
row elements like this:

    . set res [$db query "SELECT * from tbl1"]
    {one hello! two 10} {one goodbye two 20}
    . foreach row $res {puts "One: $row(one), Two: $row(two)"}
    One: hello!, Two: 10
    One: goodbye, Two: 20

The subcommands supported are ''close'', ''query'', ''lastid'', ''changes''.
It is possible to specify what string to use to represent SQL NULL.

Status: This lib is complete.

Platforms: tested under POSIX, should work under win32 without problems.
----
'''SDL'''

Goal: To provide SDL bindings for 2D graphics.

Status: this library is 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
 }

That's the result:
