Free objective modula 2 software for linux

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.

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.

objc distribution consists of the "VICI", interactive Objective-C debugger and interpreter "objc", the actual compiler.

Consists of driver script ("objc") and binary ("objc1").
"objc1" is a precompiler for C.
The binary "postlink" is used
for preparing tables for runtime initialization.
"objcrt", the Objective C Runtime Library for "objc"

This is a modern, portable, "all C" Objective C runtime

Theres absolutely no assembly language needed, nor is there a dependency on stack layout, register allocation conventions etc.

Most other runtimes, were derived from pre-"all C"-Stepstone runtimes, so this is an important point of difference.

"objpak", the "Object Pak" Objective C Collection Classes

Simple, powerful set of classes. Very portable.
Can be used to develop with different compilers, then
port with objc. Compatible with ICpak101, the collection class library described in Brad Cox book, and used by existing Objective-C packages that were developed with Stepstone objc.

"cakit", the "Computer Algebra Kit" Objective C classes

Small, concise, interface to a large set of classes for polynomial computing and arbitrary precision integer arithmetic.

Source of compiler and "oclib", a set of Objective C classes for parsing C (and the Objective C extensions to C)

"objc" and "vici" are written in Objective C itself. Its all written in portable Objective C : any Objective C compiler should be able to compile the "objc" compiler. From time to time, we try a configure with other Objective-C compilers, to ensure that our sources are still compatible with e.g. Stepstone Objective C compiler.

NOT included is a C compiler : in order to be able to use "objc", you will need to elsewhere find a compatible C compiler. This should be no problem since one of our goals - see below - is to make "objc" work with as many C
compilers as possible. On UNIX systems, the (free) "gcc" compiler is a possibility (not needed, but possible). Another possibility, is to use the (free) "lcc" compiler or the "tcc" TDF compiler system.

Installation:

Read the Install.txt file.

IMPORTANT : if this is a first-time installation, you have to start by installing the bootstrap package; do not install this package until you have installed the bootstrap package.

For every release, there is an objc-x.y.z.tar.gz package and an objc-x.y.z-bootstrap.tar.gz package.

LablGTK is a GTK+ bindings for Objective Caml.

LablGTK is an OCaml library wrapping the GTK+ API. It uses the rich type system of Objective Caml to provide a strongly typed, yet very comfortable, object-oriented interface to GTK+.

It also has support for libgnomecanvas, libpanel, librsvg, GtkGLArea and the Druid widget in libgnomeui.

It is still under development, but already fully functional. All widgets (but one) are available, with almost all their methods. The GLArea widget is also supported in combination with LablGL. LibGlade and GdkPixbuf support is also included for both versions. LablGTK2 adds support for gnomecanvas, librsvg and libpanel Many examples are provided.

Objective Caml threads are supported, including for the toplevel, which allows for interactive use of the library.

GToolKit project is a (relatively) small library that implements a simple and easy to use Objective-C interface to the GTK+ widget set.

GTK+, which stands for The Gimp Toolkit, is a library for creating graphical user interfaces for the X Window System and MS Win32 (and maybe BeOS in the future).

There are already a number of different Objective-C interface libraries around and each one has its own features, so you have to decide for yourself which one to try and use.

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.

X11Blocks package is an Objective-C Block oriented X Window System Toolkit.

X11Blocks is a layer above "Xlib" (version 11) and provides functionality that is similar to the "Xt" (X Intrinsics) and Xaw widget libraries.

Whereas much of the X Intrinsics is dedicated to implementing a classing system in C, X11Blocks uses Objective-C (an extension of C) for this purpose.

X11Blocks makes extensive use of Objective-C "Blocks", where Blocks play a role similar to callbacks in the Intrinsics.

Objective-C Blocks, also known as Block closures or Action Expressions, are pieces of code represented by instances of an Objective-C class (called Block) for delayed evaluation.

For example, the action in a "MenuItem" object is a Block.

Blocks are useful for "event-based" programming and offer a significant advantage over "callbacks" in that Blocks can refer to and alter the context in which a Block was created.
