Richard Suchenwirth 2007-10-09 - tcltcc is a Tcl extension wrapping tcc (the tiny C compiler), which was modified by MJ so it:
LGPL, download at http://code.google.com/p/tcltcc/ .
Like Odyce, it also comes with a Critcl emulation, so hopefully (at least some time in the future) people can just code against Critcl and run it with any of the three :^)
For one example usage, see ci - a tiny C interpreter.

Simple API for building DLLs
RS 2007-10-13: Since a couple of days, tcltcc can also build shared libraries (currently only DLLs for Windows, tested on Windows 95). Here's a cute and simple API for that:
package require tcc set n [tcc::dll ?name?]
Prepares the making of a DLL. Name is generated if not given, and in any case returned.
$n ccode string
Adds the string (which can be many lines) to the source buffer. Useful for #include directives, static internal functions, etc.
$n cproc name argl rtype body
Creates code to implement a Tcl command name with typed arguments argl of C return type, and appends that to the source buffer. rtype with the specified C body.
$n write ?-name str -dir path -code string?
Produces the DLL $path/$name[info sharedlibextension] by compiling the source buffer, creating an Init function which registers the commands as specified by cproc calls, and optionally adding the initialization code in string.
Working example (from the test suite):
test tcc-10.3 "new DLL interface" {
set d [tcc::dll]
$d ccode {static int fib(int n) {return n <= 2? 1 : fib(n-1) + fib(n-2);}}
$d cproc fiboy {int n} int {return fib(n);}
$d cproc hello {} char* {return "world";}
$d write -name fiboy -code {Tcl_Eval(interp,"puts {hello Fiboy!}");}
load fiboy[info sharedlibextension]
list [fiboy 20] [hello]
} {6765 world}For introspection and debugging, no cleanup takes place yet. You can see the generated code with
set tcc::dll::${n}::codeAh, tcc is great fun... :^)
