renaissance - GNUstep Development Framework
This manual page documents briefly the renaissance development
framework. This manual page was written for the Debian distribution
(based on the program's README file) because the original program does
not have a manual page.
renaissance is a GNUstep develoment framework which runs on top of the
GNUstep libraries. It also works on top of the Apple Mac OS X Cocoa
libraries, providing an opaque layer to write portable applications.
GNUstep Renaissance allows you to describe your user interface in
simple and intuitive XML files, using an open, standard format
describing the logic of the interface. At run-time, GNUstep
Renaissance will then generate the user interfaces (using the native
host OpenStep-like libraries) by reading the XML files. The
connections between the objects created from the XML files, and the
other objects in the application are done via outlets (as traditionally
in OpenStep); a new quick and intuitive syntax has been developed to
make creating outlets as easy as possible.
GNUstep Renaissance contains quite a few new ideas over previous
technologies. Some of the main end-user advantages of GNUstep
Renaissance over previous OpenStep-inspired technologies for the same
- Portability. User interfaces built using GNUstep Renaissance are
truly portable. They simply run without any change on any
OpenStep-based platform on which Renaissance has been ported
(currently, at least on both GNUstep and Apple Mac OS X).
- Open, simple and standard format. User interfaces built using
GNUstep Renaissance are saved into open, simple files which can be
edited and read on any platform using any text editor. The XML
format has been designed to be as easy to edit as possible. We will
have a specific graphical builder for GNUstep Renaissance, which will
make editing directly the XML files a rare operation; still, it's a
great advantage to be able to actually edit and inspect them directly
whenever needed. Your user interfaces will no longer be locked in
binary files which can only be edited using a specific
platform-specific application; you will be able to compare different
versions of the same user interface using diff and cvs diff (you
can't get any meaningful comparison with binary formats); and your
user interfaces will be finally stored in a readable format, which
you can read even from a terminal, making your program easier to
check. The format is so nice that I expect many hard hackers will
keep creating user interfaces directly in XML even when a graphical
editor is available!
- Easy localization. User interfaces built using GNUstep Renaissance
are much easier to translate than in all previous technologies. You
no longer need to create a new separate interface for the new
language: you can just provide the translation of the strings in a
.strings file, and GNUstep Renaissance will automatically replace
every string in the existing interface with the corresponding
translation. Previous technologies can't do this because they don't
support automatic sizing and layout of widgets.
- Themeability. Themes are a problem for traditional OpenStep-like
technologies, because a change in theme changes all the widgets
appearances and sizes. User interfaces built using GNUstep
Renaissance can survive easily a change in theme, since all sizing
and layout of widgets is done dynamically at runtime. Previous
technologies can't, and you would need to create a different user
interface for each different theme.
Renaissance is composed of the following blocks:
- AutoLayout: a collection of autolayout objects (h/v boxes, grids,
spaces, ...), providing automated runtime widget layout, similar to
what you find in most other toolkits on the market ... similar, but
better :-) The missing piece of the AppKit. Depends on gnustep-gui.
- Markup: an xml parsing/generating engine. Depends on gnustep-base.
- TagLibrary: a standard set of tag objects for use by the xml
parsing/generating engine in order to read/write gui windows, menus,
panels, etc. Depends on the previous parts: AutoLayout and Markup.
