Free gnustep software for linux

GNUstep is a cross-platform, object-oriented framework for desktop application development.

Based on the OpenStep specification originally created by NeXT (now Apple), GNUstep enables developers to rapidly build sophisticated software by employing a large library of reusable software components.

GNUstep is used in production environments at several organizations...

...an object-oriented tool development kit

The first two packages (GNUstep-make and GNUstep-base) that make up the core libraries contain a complete system for writing non-graphic tools in Objective-C. The make package allows you to setup a simple and powerful system for building, installing and packaging your tools. The base package includes all the classes necessary for writing an incredible array of tools, from wrappers for system tools to tools for communicating with web and other types of servers.

...a graphical development kit

The core libraries contain classes for developing a complete graphical application for almost any purpose. Along with our object-oriented, graphical development applications, ProjectCenter and Gorm its simple to write very complex commercial applications in weeks or months, rather than years (or often, never) in the case of other development environments.

...a desktop

Many GNUstep applications have been written to provide a powerful user experience for working on your computer. These include our workspace manager, GWorkspace, and mail client, GNUMail. GNUstep does NOT have a window manager. You can use any window manager you want, although we recommend that you use WindowMaker for a better experience (The WindowMaker project is not associated with GNUstep). Many other applications that are useful for a desktop are not contained on this web site, nor are the controlled by the GNUstep project - there are too many ideas about what a descktop should look like that we have not made up our minds about which one to endose yet. Here are some current ones:

- Project Backbone
- Etoile

GNUstep examples is a collection of programs that are meant to show programmers how to use GNUstep.
GNUstep examples includes a calculator, a currency converter, finger, fractal, puzzle, hostaddress, and ink (a simple editor).
Enhancements:
- Minor feature enhancements

GNU 3DKit is a platform independent rendering architecture based on OpenGL, written in ObjC.

GNU 3DKit is part of the GNUstep environment, which provides an object-oriented application development framework and tool set.

StepTalk project is the official GNUstep scripting framework. StepTalk is more than a scripting framework with an illusion of single objective environment between objects of scriptable servers or applications.
StepTalk, when combined with the dynamism that the Objective-C language provides, goes way beyond mere scripting. It is language independent - it uses languages as separate bundles.
The default scripting language in StepTalk is Smalltalk. This is because Smalltalk is a very simple language and it is easy to learn. There are just a few basic principles that the user has to know to be able to use the language and it is close to the natural language.
Smalltalk uses a similar approach to that of Objective-C, the language used in GNUstep itself.
StepTalk is a language independent framework. It can be extended by the "language bundles" providing other scripting languages. One experimental language bundle for Guile is included in the sources package.
Main features:
- multiple languages
- object finders
- scripting environments
- restrictions for objects methods
- dynamic module loading
Enhancements:
- The framework was ported to Mac OS X.
- The new StepTalking application was added.
- The StepTalkKit framework was added, and includes a new conversation window class with default context, a customizable toolbar, script history, and language selection.
- New view classes were added for custom script input/output.
- An AppKit bundle is included.
- The source was reorganized into more logical groups.
- Foundation and AppKit bundles now advertise all public Cocoa classes.
- Constants from Foundation and AppKit are generated from a simple constants list file.

GNUMail.app is a fully featured mail application running on Linux (or FreeBSD, OpenBSD, etc) and Apple Mac OS X.
GNUMail.app uses the GNUstep development framework or Apple Cocoa, which is based on the OpenStep specification provided by NeXT, Inc.. GNUMail.app is licensed under the GPL, and the full sources of the application are available.
GNUMail.app was written from scratch. It uses Pantomime as its mail handling framework.
Main features:
- Multiple POP3 (with APOP support) accounts with local cache support (for leaving messages on server);
- Multiple delivery agents (SMTP or local mailer);
- Mail spool file support for receiving;
- Good IMAP support with local caching;
- Full RFC822 and RFC2822 support;
- Read, compose, bounce, reply and forward mails;
- Mailbox management (create, delete, locking and transfer messages) using the Berkeley mbox format;
- Personal preferences management;
- MIME support (decode and encode);
- A full MIME types manager;
- Quoted Printable and BASE64 support;
- Address Book with groups support;
- Find Panel with regular expressions support;
- Automatic or manual fetching of your mails (users choice);
- Powerful filters that supports regular expressions;
- GPG (PGP) support through a bundle;
- Messages threading;
- And more...

GWorkspace is a clone of the NeXT workspace manager with some added features as spatial viewing, real-time auditing of the file-system, an advanced database based search system, etc.

GWorkspace application is ready for daily usage.

The workspace is supplied to help you get your work done on a computer. GWorkspace is responsible for displaying the GNUstep graphical interface called the workspace. It in this workspace where all your interaction with GNUstep begins and ends.

The most important features of GWorkspace is the maintenance of files, folders and applications. You can rename, delete and copy files and folders. With GWorkspace you can access harddisks, floppies, CDs and DVDs or USB-sticks.

This might all seem complex at first, but GWorkspace only consists of a few basic parts: The FileViewer for browsing and manipulating files, a menu containing commands and an application dock for easy access to applications which also contains the Recycler for deleting files.

ProjectCenter is GNUsteps integrated developement environment (IDE). It is based in part on NeXTs original Project Builder. It assists you in starting new projects and lets you manage your project files using a intuitive and well ordered graphical user interface.

Serg Stoyan is the current maintainer of ProjectCenter. Please contact him if you would like to submit a bug report or volunteer to improve ProjectCenter. The original author of ProjectCenter, Philippe C.D. Robert, no longer actively contributes to the application.

Over a decade ago, NeXT Computer Inc. revolutionized application development by making two great developer tools available for their operation system OPENSTEP: Project Builder and Interface Builder. These applications made application development much easier and faster and took NeXT ahead of the other computer manufacturers and operating system vendors.

Supporting the project types Application, Bundle, Library, Tool, and Aggregate, ProjectCenter automatically creates the project makefiles and aids you in the process of editing, project compilation, package building and debugging. In the future, built-in CVS support will be available, too.

ProjectCenter is a very useable application, but is still evolving. Support is there for project creation and inspection as well as basic Makefile generation. Using the Application project type, you can already create graphical applications using ProjectCenter and Gorm in conjunction.

GNUstep is a free, standard, object-oriented, cross-platform development environment meant to provide generalized visual interface design, a cohesive user interface, and look good as well. GNUstep is based on and completely compatible with the OpenStep specification developed by NeXT (now Apple Computer Inc.).
GNUstep is a whole load of things, but primarily a framework (libraries, tools, applications) for developing software. It is not a not a window manager. And the libraries are not used by WindowMaker at present, although WindowMaker shares a similar look.

At no stage will you ever run GNUstep - you will run applications and tools and will make use of its services. At some point you may well find packages distributed as GNUstep systems in the way that you get GNU/Linux systems packaged today. Look at Simply GNUstep, the GNUstep Live CD, and Project Backbone for examples.

The ProjectCenter will hopefully consist of the following capabilities somewhen in the midterm future:

* Project management
This includes versioning control, automatic makefile generation, file management etc.

* Source code editing facilities
A builtin editor will be available in a future release. This has not main priority, though.

* Debugging fascilities
A builtin debugger will be added to ProjectCenter as soon as possible!

* Documentation automation help
Automatic documentation generation using autogsdoc or another tool will be introduced later.

* UML-based case tool
