Free objective caml software for linux

Caml is a general-purpose programming language, designed with program safety and reliability in mind. It is very expressive, yet easy to learn and use. Caml supports functional, imperative, and object-oriented programming styles.

It has been developed and distributed by INRIA, Frances national research institute for computer science, since 1985.

The Objective Caml system is the main implementation of the Caml language. It features a powerful module system and a full-fledged object-oriented layer.

It comes with a native-code compiler that supports numerous architectures, for high performance; a bytecode compiler, for increased portability; and an interactive loop, for experimentation and rapid development.

ObjectivePerl is an Objective-C style syntax and runtime for perl.

SYNOPSIS

use ObjectivePerl;
@implementation MyClass
{
$someInstanceVariable;
@private: $privateInstanceVariable;
@protected: $normalInstanceVariable, $anotherInstanceVariable;
}

+ new {
return ~[$super new];
}

- setSomeInstanceVariable: $value {
$someInstanceVariable = $value;
}

- someInstanceVariable {
return $someInstanceVariable;
}
@end
then, from a calling script or class:
use ObjectivePerl;
...
my $instance = ~[MyClass new];
~[$instance setSomeInstanceVariable: "Hey you!"];
print ~[$instance someInstanceVariable]."n";

ObjectivePerl adds obj-c style syntax (although its implemented with ~[] instead of just []) along with an obj-c style runtime that is very lightweight but makes the perl runtime a little more friendly to obj-c programmers.

Why, you ask? Just because. Obj-c has the easiest-to-read syntax of just about any language. It has Smalltalk-style named arguments that are built into the method signature, so when you invoke those methods, youre forced to invoke them neatly, in a very legible fashion:

~[$window setTitleTo:"New window" withColor:0xffffff
andBackground:0x000000];

can never be misunderstood, whereas

$window->setTitle("New window", 0xffffff, 0x00000);

could be. Perl offers named arguments already in the form of hashes, but these are unwieldy (to an obj-c programmer).

Objective-C Foundation Classes is an Objective-C library.
It contains general purpose classes for easier development of applications, in areas such as data types, network, C library wrappers, collections, and compound classes.
The classes in the library are grouped in five clusters:
- DataTypes - integer, text string, fraction, bitarray, date/time, random generators, big integer, big double ...
- Collections - array, list, hash table, AVL and n-tree, circular array, graph ...
- Network - TCP/UDP server and client, HTTP client, Telnet client ...
- C-library wrappers - DBM, socket, MD5, regular expression, timer, file, directory, gzip and bzip2 file, text screen ...
- Compound - Argument parser, calendar, finite state machine, tokenizer, XML tree, discrete distribution, objective-c source tokenizer ...
Enhancements:
- A new class (DBigFraction) and a new protocol (DBitArithmetic) have been added to the library.
- There are also several bugfixes related to 64-bit platforms.
- The copy-constructor support has been improved, and as a result all collections can now be (deep) copied.
- There are some small bugfixes, and several classes have been extended with new methods.

LocalCaml is an Objective Caml library that facilitates software internationalisation by producing localised text from message catalogs.
Main features:
- Translations are written using CamlTemplate, a general-purpose templating language; they can therefore use conditional logic to adapt sentence structure and morphology to the parameters they are given.
Translators can write template macros to simplify the handling of grammatical agreement.
- Since parameters passed to templates are named, the order of parameters in a translation can be different from the order used in the original text.
- Since message text is stored in XML files instead of in source code, it can contain the full range of Unicode characters, rather than the subset allowed in OCaml source code (ISO-8859-1). It should also be easy to make catalog editing tools for translators.

Objective Modula-2 programming language is a hybrid between Smalltalk and Modula-2 based on the object model and runtime of Objective-C.

The design is an example how native Cocoa/GNUstep support can be added to static imperative programming languages without implementing a bridge.

The projects scope encompasses the design of the Objective Modula-2 programming language and the implementation of a compiler to implement it. The initial compiler will generate Objective-C source code.

Othello Game is a classic strategy game, also known as Reversi. Its objective is to finish the game with the greater amount of pieces (circles) of the same color.
This version of the Othello game supports the writing of AI plugins in C++ or Python, network games, and interface themes.
Enhancements:
- pkgconfig support was added.
- It is now easier to write AI plugins.
- An installation guide, and a tutorial for writing plugins were incuded.
- It is now possible to disable Python support from the configuration.
- New icons were provided.

Generally, mod_ocaml is a flexible module for use with the famous Apache Web Server. Probably you know how to benefit of other modules with unbelievable capabilities, like PHP (mod_php4) or Perl (mod_perl).

One of the advantages of the Apache Server is the possibility to extend its features by adding modules to your configuration. At this point, mod_ocaml comes up.

mod_ocaml is designed to work with the 1.3 family of Apaches all over the world.

OCAML is derived from the CAML language. We include the description from its home at INRIA here:

Caml is a programming language, easy to learn, easy to use, and yet amazingly powerful.

It is developed and distributed by INRIA (the main French research institute for computer science), since 1984. It is freely available for Unix, PC or Macintosh.

Objective Caml (OCAML) is a general purpose programming language that combines
functional, imperative, and object-oriented programming. The language is statically typed; its type system ensures the correct evaluation of programs.

Types are automatically inferred. The language offers powerful constructions such as user-definable data-types, the ability to define functions by pattern-matching, and an exception mechanism. Programming in the large is facilitated by a full-fledge class-based object-oriented layer and an expressive module system.

Installation

Find your installed apxs, usually in /usr/bin, or /usr/local/apache/bin.

Call apxs -c mod_ocaml.c to compile the module

Copy the created file mod_ocaml.so to your apache libexec directory, e. g. /usr/local/apache/libexec.

Make two entries in your httpd.conf configuration file:

LoadModule mod_ocaml mod_ocaml.so
AddHandler ocaml-parsed .ocml

Restart your apache web server. Now it is ready to process your OCML-files.

Usage

You simply write poor old HTML code and save it under your webserver root. Choose the extension you entered at the "AddHandler" directive in httpd.conf (per default, this is .ocml). So you save a file named, e. g. test.ocml.

Until now, you didnt use any of the mod_ocaml benefits. Try to include OCAML code, and it will be displayed "as is". Since you want your OCAML code to be interpreted and evaluated, you have to inform mod_ocaml of this:

< ?ocml

Printf.printf ("This is generated by the OCAML interpreter.");;

? >

As you can see, the init tag for your OCAML parts is "<<less
