ADML language is a server-side scripting language with Mysql database suport.

About Apache:

Apache HTTP Server is a free software/open source HTTP web server for Unix-like systems (BSD, Linux, and UNIX systems), Microsoft Windows, Novell NetWare and other platforms. Apache is notable for playing a key role in the initial growth of the World Wide Web, and continues to be the most popular web server in use, serving as the reference platform against which other web servers are designed and judged.

Apache features highly configurable error messages, DBMS-based authentication databases, and content negotiation. It is also supported by several graphical user interfaces (GUIs) which permit easier, more intuitive configuration of the server.
The Apache HTTP Server is developed and maintained by an open community of developers under the auspices of the Apache Software Foundation.

The Complex Language project is an object oriented programming language intended for scripting or rapid prototyping of applications.
The design goals were to have very few simple but powerful concepts and to be easy to use and easy to learn. The project provides a working interpreter along with a complete specification of the language.
Enhancements:
- This is the first release of the specification and the corresponding interpreter.
- The corresponding library is very poor, and there are probably still bugs in the interpreter.

Language::XSB is a Perl module that allows you to use XSB from Perl.

SYNOPSIS

use Language::XSB :query;
use Language::Prolog::Types::overload;
use Language::Prolog::Sugar vars=>[qw(X Y Z)],
functors=>{equal => =},
functors=>[qw(is)],
chains=>{plus => +,
orn => ;};

xsb_set_query( equal(X, 34),
equal(Y, -12),
is(Z, plus( X,
Y,
1000 )));

while(xsb_next()) {
printf("X=%d, Y=%d, Z=%dn",
xsb_var(X), xsb_var(Y), xsb_var(Z))
}

print join("n", xsb_find_all(orn(equal(X, 27),
equal(X, 45)), X)), "n";

ABSTRACT

Language::XSB provides a bidirectional interface to XSB (http://xsb.sourceforge.net/).

From the XSB manual:

XSB is a research-oriented Logic Programming and Deductive
Database System developed at SUNY Stony Brook. In addition to
providing all the functionality of Prolog, it contains
features not usually found in Logic Programming Systems such
as evaluation according to the Well Founded Semantics through
full SLG resolution, constraint handling for tabled programs,
a compiled HiLog implementation, unification factoring and
interfaces to other systems such as ODBC, C, Java, Perl, and
Oracle

This package implements a bidirectional interface to XSB, thats means that Perl can call XSB that can call Perl back that can call XSB again, etc.:

Perl -> XSB -> Perl -> XSB -> ...

(Unfortunately, you have to start from Perl, XSB->Perl->... is not possible.)
The interface to XSB is based on the objects created by the package Language::Prolog::Types. You can also use Language::Prolog::Sugar package, a front end for the types package to improve the look of your source (just some syntactic sugar).

To make queries to XSB you have to set first the query term with the function xsb_set_query, and then use xsb_next and xsb_result to iterate over it and get the results back.

Only one query can be open at any time, unless when Perl is called back from XSB, but then the old query is not visible.

Language::Logo Perl module is an implementation of the Logo programming language.

SYNOPSIS

use Language::Logo;

my $lo = new Logo(update => 20);

$lo->command("setxy 250 256");
$lo->command("color yellow");
$lo->command("pendown");

# Draw a circle
for (my $i = 0; $i < 360; $i += 10) {
$lo->command("forward 10; right 10");
}

$lo->disconnect("Finished...")

This module provides an implementation of the Logo programming language, with all of the necessary drawing primitives in a Tk Canvas. The Canvas object is also referred to as the "screen".

The first construction of a Language::Logo object causes a server to be created in a separate process; this server then creates a Tk GUI with a Tk::Canvas for use by the clients "turtle", and responds to all requests from the clients commands. In this way, multiple clients may be constructed simultaneously -- each one with its own "turtle".

In this first release, not all of the Logo language is implemented. Rather, the primary commands available are those which directly affect the turtle, and are related to drawing on the screen. The intent is to use the Logo in conjunction with Perl as a sort of "hybrid" language; Perl us used as the higher-level language layer through which all loop constructs, conditionals, and data-manipulation is done. This allows for a substantial level of programming power.

Short Markup Language is an alternative XML notation that is a character by character equivalent with XML.
Short Markup Language covers all legal XML constructs, including processing instructions, doctype declarations, internal DTD subsets and namespace declarations.
Currently SML-to-XML and XML-to-SML converters have been implemented. The converters are based on efficient JavaCC parsers, and can be run from the command-line run or an Ant-task.
Short Markup Language is an open-source project, published under the GNU General Public Licence.
Enhancements:
- First release includes SML to XML and XML to SML converters in an easy to use executable jar.

Arena Scripting Language is a light-weight scripting language. The language uses a syntax and library similar to that of ANSI C, but adds automatic memory management and runtime polymorphism on top of that.
Main features:
- syntax similar to ANSI C
- standard library similar to ANSI C
- automatic memory management
- runtime polymorphism
- support for exceptions
- support for anonymous functions
Enhancements:
- This release changes the system() library function to return the raw exit status as given by the operating system.
