Modern Fortran modules that contain interfaces to the free X11 graphics library EGGX/ProCALL. The EGGX/ProCALL library provides fast and simple drawing routines on Linux, Unix, and Cygwin, directly callable from C or FORTRAN 77.
EGGX/ProCALL 2003 is a wrapper around EGGX/ProCALL that includes:
- Fortran 90 interfaces to the FORTRAN 77 ProCALL subroutines (module
procall). - Selected Fortran 2003 ISO C binding interfaces to C functions in EGGX that do not have a FORTRAN counterpart (module
eggx). - Named parameters of key codes, colour palettes, and output formats.
Simply clone the GitHub repository and execute the Makefile:
$ git clone https://github.com/interkosmos/eggx-procall-2003
$ cd eggx-procall-2003/
$ make
The EGGX/ProCALL 0.95 source code is included in directory vendor/eggx-0.95/.
Link your Fortran application with vendor/eggx-0.95/libeggx.a,
libeggx2003.a, and -lX11, for instance:
$ gfortran -o demo demo.f90 libeggx.a libeggx2003.a -lX11
See directory examples/ for some demo applications:
- julia draws the Julia set.
- mandelbrot draws the Mandelbrot set.
- munch renders a graphical pattern.
- peano draws a Peano curve.
- snake sprites-based implementation of the snake game.
- starfield lets you fly through a starfield.
- tiles draws text and a tileset to screen.
- wireframe renders the 3D model of a Tie-Figher.
Compile all programs with:
$ make examples
Or, use the name of a particular example. Run each program from its respective directory:
$ make <name>
$ cd examples/<name>/
$ ./<name>
For the official documentation, see the PDF file vendor/eggx-0.95/eggx_procall.pdf.
Generate the source code documentation with
FORD. Add FORD with pip, for example:
$ python3 -m venv virtual-environment/
$ source virtual-environment/bin/activate
$ python3 -m pip install ford
Or, instead, just install the package in your user directory:
$ python3 -m pip install --user ford
Then, run:
$ ford project.md -d ./src
