Application wish list

2006-12-11T01:13:21Z

Boomer: /* CronniX - A cron front end */

What applications do you want for GNUstep? Please check the [[:Category:Applications|list of applications]] before adding.

== Database ==

=== DatabaseModeller.app ===

See [[DBModeler]], currently a work in progress.

=== Database management ===

A desktop software (like [http://www.flex.ro/pgaccess/ PgAccess] for example) to manage database. This program could use the GDL2 (Gnustep Database Library). It could be a good exercice and demonstration of this very good library.

== Development ==

=== Project Management app ===

Something like [http://mrproject.codefactory.se/screenshots.php MrProject]. It has to be simple, not overbloated as MS Project.

=== nib2gmodel/nib2gorm without OPENSTEP/MacOSX ===

I want;but I heard it is so hard to implementation. :-(

=== CVS app ===

Port CVL.

== Graphics ==

=== Blender ===

Blender has recently (since October 2002) gone GPL. Consisting of porting the Blender GUI/WM abstract library GHOST, using NSOpenGLContext, or a CoreGraphics implementation one day. Objective-C++ might be needed for implementing GHOST, but probably can be worked around easily enough. There is an OSX port, probably using CoreGraphics.

[http://www.blender.org/ Blender Foundation Homepage]

Most of Blender is written in C++ doesn't seem to use CoreGraphics but Apple's GL.

=== OmniGraffle clone ===

(I don't really know what this is, but people have said they want one. Someone please add a description! :)

This is for diagram, UML ....
I 'm thinking to write it. But not *right now*.
It will have probably a Gorm-feel

[http://www.omnigroup.com/applications/omnigraffle/ OmniGraffle] was a clone of Lighthouse Design's Diagram.app, which was a re-working of the NeXT Developer Example Sketch.app, adding rubber-banding / angular connection lines.

=== OmniOutliner clone ===

This is a really cool app which can be used for anything. Mostly i think it is used to organise your minds while being creative (some kind of knowledge manager).

The inspiration for this was Jayson Adams' Millennium Software's NoteBook.app, which lives again as the (commercial) program [http://www.aquaminds.com/ NoteTaker].

=== Painting app (photoshop) ===

Bitmap drawing app.

Think Photoshop, not [http://www.gimp.org/ The Gimp].

In fact, forget that. Something new.

Something usable - can do Photoshop, but easy to learn. The Gimp can nearly do photoshop, but who can use it?

It would be great if it consisted of two parts - a very small very useful image viewer/manager (eg gqview) and the actual editor plugin (the big part). So installing image-core would give a very small useful app, then adding image-edit would make it into photoshop.

When opening an image file eg by clicking on it or running image-core thefile.jpg then only the core apps should start, so it starts real quick. If i right-click and choose edit or something .. THEN the other stuff is pulled in.

Or whatever. Just an idea. But makes development path cool. Could also have a vector plugin, or whatever.

Maybe we should wait, when (if?) Gimp gets '[http://gegl.org/ gegl]'ed.
then having a decent photoshop like app would be as simple as writing a gui for the gegl foundation.
+ gives us a nice featureset + plugins!

Maliwan project is aiming to achieve the same goal of GEGL. Right now GEGL isn't even half complete but we can still reimplement it base on GEGL's design. lastlife is waiting for you in irc if you want to discuss the idea. Maliwan is planned to be the heart of the BluTulip which is the actual application.

* porting http://seashore.sourceforge.net/ from their website: Seashore is an open source image editor for Cocoa. It features gradients, textures and anti-aliasing for both text and brush strokes. It supports multiple layers and alpha channel editing. It is based around the GIMP's technology and uses the same native file format.

a screenshot is here: [http://seashore.sourceforge.net/screenshot.php] which looks very clean and easy to use.

=== Pixen (Pixel Art Tool) ===

[http://www.opensword.org/ Pixen] is a decent, open source pixel art tool and there aren't alot of free or professional programs like it. There is also a compliment tool by the same guys for mapping called Reptile.

A port can be found [http://home.gna.org/gsimageapps/ here].

== MultiMedia ==

=== iTunes/Rhythmbox clone ===

It would be nice to see a music or video player with real music/media management like [http://www.gnome.org/projects/rhythmbox/ Rhythmbox] or [http://www.apple.com/itunes/ iTunes]. iTunes has started to support management of movies and videoclips, so maybe media management is the way to go?

=== DivX/XViD/DVD/VCD Player ===

I see that there was at least an attempt to port mplayer at one point but it seems to be dead. Maybe [http://www.videolan.org/ VLC] which does have an OSX version, could be ported.

''Looks cool, but requires CoreFoundation'' -- cbv

== Networking ==

=== ICQ ===

And other instant messengers.

* Check http://freshmeat.net/projects/fireapp/
* See [[Grouch]].

=== Web browser ===

Seems to be a popular request :).

* Most of the best ideas ([http://www.mozilla.org/projects/camino/ Camino] and [http://www.apple.com/safari/ Apple's Safari]) rely on Objective-C++ support that wasn't available with the stock GCC until the 4.1 snapshots.

* Stefan began porting [http://mac.wms-network.de/gnustep/WebCore/blog/ Webcore to GNUstep] by splitting the Objective-C++ code into C++ and Objective-C modules. Unfortunately, while it can render pages using an (old) version of WebCore, it still lacks a significant amount of implementation before it could actually be the GNUstep WebKit.

* [[User:Geocar]] worked on Stefan's code for a bit to get something that looked like this:
[[Image:webkit-on-gnustep.png]]
before deciding to try using the new Objective-C++ compiler in GCC. Will note how this all turns out :)

* I could port [http://ibn.com/~hdiwan/orchidWeb.html OrchidWeb] to GNUStep. I'd just need enough examples on developing the views from code to do it.

* Apparently, [http://www.caminobrowser.org/ Camino] is written in Objective-C++, which GCC can't compile (although Apple is supposed to have contibuted the patch). Until gcc can compile mixed obj-c and c++, it can't be ported. There is a thread about this at [http://linuxfr.org/2003/03/10/11647.html] (it's in french).

=== Video conferencing software ===

There's [http://www.gnomemeeting.org/ Gnomemeeting] (excellent piece of software), but I don't like Gnome too much (all those dependencies).

Update: Gnomemeeting 0.9.6 is supposed to work without Gnome libs (limited functionality).

== PIM ==

=== Calendar ===

check SKYRIX libs (Opengroupware).
http://www.opengroupware.org/cvsweb/cvsweb.cgi/OpenGroupware.org/SOPE/skyrix-core/NGiCal/

[http://www.linuks.mine.nu/agenda/ Agenda.app] is young and could use some work.

=== Task management app ===

Chronographer (lobbying by ludovic) + libical
or
~TaskManager (lobbying by Fabien) + libical

Check SKYRIX libs (Opengroupware)

== Security ==

== Text Processing / Office ==

=== Abiword (Word Processor) ===

A port of the Cocoa version of [http://www.abisource.com/ AbiWord] would be great, considering a word processor is a pretty vital application, and that Abiword is a pretty good one.

=== Spreadsheet ===

A spreadsheet application would be great for GNUstep. A clone of Lotus Improv or Lighthouse Design's Parasheet would be a nice thing for GNUstep to have.

=== CSS/html editor ===

A cool html/css editor - emphasis on the css structural side.

Object oriented properties application to CSS element definitions, and insert those properties into HTML in web pages. Don't worry about WYSIWIG - that's what web browsers are for, displaying web pages. Just make a object-oriented CSS/HTML editor.

Maybe port [http://www.w3.org/People/Berners-Lee/WorldWideWeb.html Nexus] for that?

''This might actually be feasible, however, Nexus is based on [http://www.w3.org/Library/ libwww] and its source is, well, very NeXTSTEP'ish...'' -- cbv

=== A text editor ===

A simple text editor that can read and write plain or rich text, including both simple word processing functionality (nothing too splashy, like frames) and optional programming features (like syntax highlighting -- not just coloring; controllable tabs; tab v. space indentation, multiple language support). Programming features could be provided by a bundle, but it would be good to for the app to be designed with that bundle in mind.

This editor which is to guarantee me world domination includes a split view where the other pane locates and displays the corresponding end-tag/start-tag when programming.

Ink is not that editor. :)

[http://www.softpanorama.org/Editors/index.shtml Softpanorama] seems to give a good overview of editors

''We have to distinguish between a text editor as programming tool (CodeEditor.app) and a text editor as a word processor (WordProcessor.app?). '' They are two different approaches to text editing and text processing.

Source code editing view and associated inspector panels and preferences should be provided as a framework, so the SourceView should be reused in other apps. CodeEditor should be only some default wrapper for that framework.

WordProcessor.app sould be an application that extends NSText system. (With easy-to-use paragraph style editing)

How about interfacing with [http://www.scintilla.org Scintilla]?
-- Hasan --

=== A simple DTP application ===

A simple frame-based application for desktop publishing. Something like [http://www.calamus.net/ Calamus] ([http://www.calamus.net/man/index_us.htm here] is the documentation of tools and modules). Nothing fancy, just application that can lay out frames, control text flow, use paragraph styles and master pages.

I'd rather see TeXView.app come back myself.... I think it's far more feasible (doing a decent page layout app is _hard_ just as Donald E. Knuth). Perhaps better still would be to take advantage of LyX's ``GUI-independence'' and provide a GNUstep front-end for it, http://www.lyx.org .

No, nothing like LyX or TeX. I have in mind a ''visual'' page layout editing tool with features as described above (similar to PageMaker). LyX and TeX are a bit different approaches and should be alternatives to Frame based DTP application.

- Stefan

I think a heavy-weight drawing package w/ page layout features would be a better solution here (this is the workflow I'm using on my NeXT Cube now), then it could be tied into an XML-based workflow in a fashion like to Apple's new Keynote, perhaps in a fashion like to Pages-by-Pages. To describe my workflow a bit---I now use Altsys Virtuoso on my NeXT Cube w/ Omega (Unicode-aware TeX variant) for most of my page layout. IME, if a document gets too large to manage w/ Altsys Virtuoso, it might as well go into TeX... Not that I'd mind seeing a replacement for PasteUp.app, I just think that a drawing program is more immediately important / useful.

For simple DTP utility, I'd dearly love to see a re-creation of [http://members.aol.com/willadams/gnustep/apps/type/touchtype.html TouchType.app]

- William

Maybe you should take a look at [http://www.texmacs.org/ TeXmacs]. Looks promising and is in great need of a GNUstep frontend.

- david.

Interesting. I'd seen TeXMacs mentioned on comp.text.tex quite often, but hadn't realized it had gotten as far as it had. Interesting counterpoint to LyX.
- William

One really interesting thing would be to have a fame class which would useful enough so it could be used to put together a simple DTP Application but which would be flexible enough that it could be available to any application - the text control is a standard control for windows managers like MS Windows or Gnome. If there were an equivalent "flowing graphic control", you'd have a powerful building block indeed (note that in MS windows, the text control is actually poor enough that no credible application can built around besides notepad).
Also, for a programming text editor, scintilla is great. One thing to consider is that for DTP/HTML editor, what you would want would be a *superset* of the scintilla interface. It would be great to add all the different features in such a way that you didn't have interfaces duplicating each other's functionalities.

=== Digital Librarian-like ===

I would really, really like a Digital Librarian for GNUstep. Basically, imagine an application that manage your documents the same way iTunes manage your music or iPhoto your photos... (to take well-known OSX apps as example ;-)

It would provide 1) automatic management of the documents by projects/ideas/whatever metadata 2) index your documents to let you search quickly in it 3) handles bibliography
As a postgrad student I have a LOT of articles in PDF/PS/DVI/html on my hard drive, and such an application would be really nice to help managing that.

A screenshot of Vertex Librarian, a similar program for NeXTSTEP: http://www.levenez.com/NeXTSTEP/VertexLibrarian.jpg

http://unix.freshmeat.net/projects/mylibrary/? [[User:Madleser|Madleser]] 17:19, 2 October 2006 (CEST)

== Misc ==

=== Old NeXTSTEP/OPENSTEP apps ===
See [http://www.levenez.com/NeXTSTEP/meApps.html this side (in French)] for a list.

=== Frontend for different platform to [http://www.granddictionnaire.com/ Grand Dictionnaire (in French)] ===

=== Keyboard switcher application ===

=== Google.app ===

* Complete with ApplicationServices
* WebBrowser integration
* Using proper NS* classes for HTML retrieval
* Ability to select which Google server (www.google.ca, www.google.co.jp)
* Google News, Google Groups, Google Images too.

=== DMG.app? ===

* Installer/extractor/viewer for DMG images.
* Create DMG packages
* Useful for OSX source packages

''Note:'' The DMG format is Apple proprietary and undocumented. Basically, DMG support is only available under OSX and its unlikely to change.

=== CronniX - A cron front end ===

http://www.abstracture.de/projects-en/cronnix

That won't be easily portable, as different OSs use a different cron setup. Eg. BSD has (and uses) both, /etc/crontab __and__ /var/cron/tabs/<username> ...

=== PfaEdit - A font editor ===

PfaEdit has its name changed to [http://fontforge.sourceforge.net/ FontForge].

Actually, Cenon (see above) is able to do some limited font editing. Not to knock pfaedit, I use it a lot and think it's a way cool program. Wonder if the two could be merged somehow.

=== GuileServices / StepTalk Services ===

On NeXTSTEP there was an application (service?) called [http://www.doubleu.com/TickleServices.html TickleServices] that allowed you to write your own services in the Tcl language. Something along these lines, but using guile/steptalk would be a nice addition to gnustep.

=== Printer.app ===

An application/framework for managing printers, printer properties and print queues. (CUPS frontend?) (NOTE: To an extent, GNUstep already has CUPS support, and has number of builtin classes and panels for managing printers and printer settings. They may just need to be extended a little for different uses and environments.)

=== Growl! (Global notification system) ===

[http://growl.info/ Growl!] uses distributed notification center to display a graphic message on screen. Every application can send messages to it, for example, when new emails arrive, buddies sign in the instant messager, a task end, etc. It is very easy to implement.

''Parts require CoreFoundation and/or WebKit'' -- cbv

Perhaps the CoreFoundation bits could be handled by [http://developer.apple.com/opensource/cflite.html CF-Lite].

''Since about version 299 CoreFoundation doesn't compile properly anymore on systems other than Darwin.'' -- [[User:Cbv|cbv]]

== Introductory Articles on GNUstep Development ==

{{Stub}}

=== [http://www.gnustep.org/resources/documentation/Developer/Base/ProgrammingManual/manual_toc.html Introduction to GNUstep (Foundation) Programming] ===

The aim of this manual is to introduce you to the Objective-C language and the GNUstep development environment, in particular the Base library. The manual is organised to give you a tutorial introduction to the language and APIs, by using examples whenever possible, rather than providing a lengthy abstract description.

While Objective-C is not a difficult language to learn or use, some of the terms may be unfamiliar, especially to those that have not programmed using an object-oriented programming language before. Whenever possible, concepts will be explained in simple terms rather than in more advanced programming terms, and comparisons to other languages will be used to aid in illustration.

=== [[Writing Makefiles]] ===

The Makefile package is a system of make commands that is designed to encapsulate all the complex details of building and installing various types of projects from libraries to applications to documentation. This frees the developer to focus on the details of their particular project. Only a fairly simple main makefile need to be written which specifies the type of project and files involved in the project.

=== [ftp://ftp.gnustep.org/pub/gnustep/core/gnustep-examples-1.0.0.tar.gz Sample GNUstep Programs] ===

This isn't really an article but rather a collection of small "codified guides" for the pragmatic programmer who wants to explore GNUstep by looking at and messing around with example code. This is best done while reading about basic concepts of OpenStep or Cocoa with the API documentation ([[Foundation]], [[AppKit]]) open in the background.

== General ==

=== [[Writing portable code|Coding for Portability]] ===

Writing code that will compile and then run on different platforms can be surprisingly easy. This guide describes some straight-forward steps to take to make your program easy to port to new platforms.

=== [[Property Lists|Using Property Lists]] ===

A regular issue that programmers face is storing structured configuration information, and reading it back. GNUstep has a standard mechanism that can be used for this task, amongst others: Property Lists.

== Graphical Applications ==

=== Simple Graphical Application Design ===

GNUstep includes several sophisticated development tools. GNUstep GUI interfaces are designed using [[Gorm]] (Graphical Object Relationship Modeler), an elegant application developed by Gregory Casamento. (See his [http://heronsperch.blogspot.com/ blog] for the latest news on GORM.) There are two proto-IDEs, [[ProjectCenter]] and [[ProjectManager]].

There are several introductory tutorials for using these development tools. The first [http://www.gnustep.it/pierre-yves/index.html tutorial] by Pierre-Yves Rivaille is a classic demonstrating the process used to create the ubiquitous currency converter application. A second [http://www.nongnu.org/gstutorial/ tutorial] by Yen-Ju Chen is somewhat more in-depth and extensive.

Nicolas Roard created a [http://gnustep.org/experience/DevelopmentDemonstration.html video] demonstrating the process of developing a simple calculator, and another [http://home.gna.org/pmanager/videos.html video] here by Sašo Kiselkov if you feel the need to create another currency converter.

=== [[Document based applications|Document-based Application Design]] ===

One of the most common use-patterns of applications on modern platforms is that of document-based applications --- applications which can have several active user-controlled contexts. Some familar examples might be a word processor where the user may have multiple document windows concurrently, or a web browser which allows a user to have a number of different browser windows open at the same time. This guide provides information and tips on how to code this style of application.

There are several introductory tutorials for using these development tools. The first [http://www.gnustep.it/pierre-yves/index.html tutorial] by Pierre-Yves Rivaille is a classic demonstrating the process used to create the ubiquitous currency converter application. A second [http://www.nongnu.org/gstutorial/ tutorial] by Yen-Ju Chen is somewhat more in-depth and extensive.

Nicolas Roard created a [http://gnustep.org/experience/DevelopmentDemonstration.html video] demonstrating the process of creating a simple calculator.

=== [[Document based applications|Document-based Application Design]] ===

One of the most common use-patterns of applications on modern platforms is that of document-based applications --- applications which can have several active user-controlled contexts. Some familar examples might be a word processor where the user may have multiple document windows concurrently, or a web browser which allows a user to have a number of different browser windows open at the same time. This guide provides information and tips on how to code this style of application.

Document based applications

Boomer: Added link to video tutorials.

Document based applications are those that are primarily concerned with user documents, allowing multiple (context-sensitive) document windows and a consistent mechanism for file loading and saving. GNUstep provides a model and associated services, for the rapid development of applications following this paradigm.

Document based applications in GNUstep use NSDocument and NSDocumentController to support and coordinate this behaviour. Below are some articles describing how you can add this functionality to your program, and the role these classes in play in gnustep-gui.

Sašo Kiselkov has put together several [http://home.gna.org/pmanager/videos.html video tutorials], one of which shows the process of creating a document-based application using ProjectManager.

GNUstep Installation Process

2006-04-07T23:41:33Z

Boomer: Add a link to Dennis Leeuw's GNUstep Build Guide for Unix Systems.

At the moment, the ways available to install GNUstep is heavily dependent on the host operating system platform.

==Installing from source code==

If you wish to install from source code, instructions are available from [http://www.gnustep.org/resources/documentation/User/GNUstep/gnustep-howto_toc.html GNUstep Howto] - and if you want to stay on the bleeding edge, check out point 7 on that page or Dennis Leeuw's [http://gnustep.made-it.com/BuildGuide/index.html GNUstep Build Guide for Unix Systems].

* latest instructions for [[Installation on Windows]]
* latest instructions for [[Gorm Installation On Windows]]
* latest instructions for [[Installation of 32bit GNUstep on 64bit Linux]]

==Using your native packaging system==

Many platforms offer native GNUstep packages that may be installed in the same way that other software is commonly installed. Some information on platform-specific packages can be located at [[Platform_compatibility]].

==Some aspirations==

GNUstep installation process could be and should be as simple as "pkg-inst GNUstep-1.0" across GNUstep supported OS plaforms.

Given GNUstep's cross-platform approach to application development activities, the application mangement activies should also be united across OS platforms.

For "pkg-inst GNUstep-1.0" details, please see [[Package_management]].

Can example be provided about "production environment in serveral organization" ? this will clear the doubt of people on GNUstep stability.

Thank you ([[User:TJ Yang ]])

Internationalisation in the Users section is probably misnamed and misspelled for this site.

For the user their issue is normally Localisation, but even this isn't necessarily clear. I would argue for terminology like "Configuring language, script and input methods" or even something as formal as "National language configuration".

Internationalisation is a word most often used to describe the process of modifying ''code'' to ''support'' varied text encodings, number formats, currencies and so on and is a developer topic. Localisation is a word used most consistently for ''translation or conversion'' of an application interface and documentation into ''specific'' human languages, date and number formats etc and is probably a developer or volunteer topic.

Even though my personally-preferred spelling in English is the Commonwealth variant, the most wide-spread spelling for Internationalization and Localization are the American-style 'z' spellings. Let's make it easier for people to find what they are looking for in search engines. When a user is trying to find out how to localise their script input and national language preferences, what terms are they going to search for? The link and page should be somehow connected to that.

== A question concerning non-ASCII input in GNUstep applications ==

Hello folks!
I tried to use GNUstep applications for my day-to-day tasks but I couldn't make them accept any text input except ASCII characters. When I switch to Russian, all applications refuse input. Is this the right way they should work now? As I know, there isn't any problems with Russian input in the original OpenStep environment. I use XKB and ru_RU.KOI8-R locale. Maybe it's necessary to use ru_RU.UTF8 or you know any other workarounds? All non-GNUstep applications work perfectly.

likely the important thing is to set the GNUSTEP_STRING_ENCODING environment variable to NSKOI8RStringEncoding. There is an [[http://www.gnustep.org/resources/documentation/User/Gui/LanguageSetup.html Asian language support]] page on the gnustep website, that also contains information that could be useful for other languages.

Thank you, it works :) I also had to make some font assignments not covered in "Asian language support" document (Preferences.app let me find out about them and fix menu font, etc.), but the direction was right.
