Agar is a modern open-source,
cross-platform toolkit for graphical
applications implemented in C, C++ and Ada (with bindings to other
languages in development).
Designed for ease of integration, it follows the philosophy of building
the GUI around the application and not the other way around.
Unlike most other GUI toolkits, Agar takes maximum advantage of hardware
graphics acceleration when it is available via OpenGL, but it also
supports traditional framebuffer interfaces such as
SDL direct video.
The Agar API is entirely thread-safe when Agar is compiled with optional
threads support.
The distribution includes two libraries:
Agar-GUI implements the base Agar GUI
system and a comprehensive set of
standard widgets.
Agar-GUI is object-oriented and relies heavily on inheritance, virtual
functions and virtual filesystems. This functionality is implemented by
the GUI-independent Agar-Core library, which also
includes various utility and portability interfaces.
The Agar distribution also includes some more specialized libraries aimed
at specific applications, such as
Agar-MATH,
Agar-RG,
Agar-VG and
Agar-DEV.
Some of our other toolkits which extend (and rely on) Agar include
FreeSG,
Edacious and
cadtools.
Agar is free software. Its source code is freely usable and re-usable by
everyone under a BSD license, which allows
use in commercial applications free of charge.
Agar is stable, well-maintained and has been growing organically since
early 2002.
The Agar project is sponsored by
Csoft.net:
Security conscious, high-availability Unix hosting on redundant
server arrays.

The Agar GUI library is designed to work under almost any platform that
provides a graphic display and some kind of input device.
Currently, there are drivers for
SDL and
OpenGL.
The OpenGL mode makes efficient use of hardware acceleration.
The API is simple, object-oriented and unobtrusive (e.g.,
bindings reduce the need for event
handlers to the minimum).
Implementing new widgets as part of an application or library is easy,
and the Agar object system provides you with inheritance, even if you are
only using C.
See the Agar FAQ for more details.

A portable, general-purpose math library with focus on performance.
It can be compiled against specific precisions and architecture
extensions.
It provides a consistent interface for common operations in basic linear
algebra, complex numbers and computational geometry, independent of
storage format and solver backend.
For example, for the task of solving linear equations it is possible to
switch between ordinary LU decomposition / backsubstitution and a sparse
matrix solver (one based on the excellent
Sparse1.4
is included).
Agar-MATH also extends the Agar-GUI library with bindings support for its
basic types and widgets such as
M_Plotter
and
M_Matview.

A library for generating and manipulating feature-based pixmap
elements (either static or animated). It uses an image format which allows
directives, transformations and instancing of graphical elements.

A simple 2D vector graphics library which allows developers to specify
hierarchical sketches consisting of elements such as lines, curves and
text. It was designed mainly for editors (the schematics editor in
in Edacious is an
example application).
For dimensioned/constrained technical drawings, the SK library
(in FreeSG) is a better option than
Agar-VG (although still under development).

Due to some changes in the build system, users of the latest
development version of Agar (as of r8187) who rely on the
make proj feature, must upgrade to
BSDBuild-2.5.
