The Factor programming language ------------------------------- This file covers installation and basic usage of the Factor implementation. It is not an introduction to the language itself. * Contents - Compiling the Factor VM - Libraries needed for compilation - Bootstrapping the Factor image - Running Factor on Unix with X11 - Running Factor on Mac OS X - Cocoa UI - Running Factor on Mac OS X - X11 UI - Running Factor on Windows - Command line usage - The Factor FAQ - Source organization - Community * Compiling the Factor VM The Factor runtime is written in GNU C99, and is built with GNU make and gcc. Factor supports various platforms. For an up-to-date list, see <http://factorcode.org/getfactor.fhtml>. Factor requires gcc 3.4 or later. On x86, Factor /will not/ build using gcc 3.3 or earlier. If you are using gcc 4.3, you might get an unusable Factor binary unless you add 'SITE_CFLAGS=-fno-forward-propagate' to the command-line arguments for make. Run 'make' ('gmake' on *BSD) with no parameters to build the Factor VM. Compilation will yield an executable named 'factor' on Unix, 'factor.exe' on Windows XP/Vista, and 'factor-ce.exe' on Windows CE. * Libraries needed for compilation For X11 support, you need recent development libraries for libc, Freetype, X11, OpenGL and GLUT. On a Debian-derived Linux distribution (like Ubuntu), you can use the line sudo apt-get install libc6-dev libfreetype6-dev libx11-dev glutg3-dev to grab everything (if you're on a non-debian-derived distro please tell us what the equivalent command is on there and it can be added). * Bootstrapping the Factor image Once you have compiled the Factor runtime, you must bootstrap the Factor system using the image that corresponds to your CPU architecture. Boot images can be obtained from <http://factorcode.org/images/latest/>. Once you download the right image, bootstrap Factor with the following command line: ./factor -i=boot.<cpu>.image Bootstrap can take a while, depending on your system. When the process completes, a 'factor.image' file will be generated. Note that this image is both CPU and OS-specific, so in general cannot be shared between machines. * Running Factor on Unix with X11 On Unix, Factor can either run a graphical user interface using X11, or a terminal listener. If your DISPLAY environment variable is set, the UI will start automatically: ./factor To run an interactive terminal listener: ./factor -run=listener If you're inside a terminal session, you can start the UI with one of the following two commands: ui [ ui ] in-thread The latter keeps the terminal listener running. * Running Factor on Mac OS X - Cocoa UI On Mac OS X, a Cocoa UI is available in addition to the terminal listener. The 'factor' executable runs the terminal listener: ./factor The 'Factor.app' bundle runs the Cocoa UI. Note that this is not a self-contained bundle, it must be run from the same directory which contains factor.image and the library sources. * Running Factor on Mac OS X - X11 UI The X11 UI is also available on Mac OS X, however its use is not recommended since it does not integrate with the host OS. When compiling Factor, pass the X11=1 parameter: make X11=1 Then bootstrap with the following switches: ./factor -i=boot.<cpu>.image -ui-backend=x11 Now if $DISPLAY is set, running ./factor will start the UI. * Running Factor on Windows XP/Vista If you did not download the binary package, you can bootstrap Factor in the command prompt: factor.exe -i=boot.<cpu>.image Once bootstrapped, double-clicking factor.exe starts the Factor UI. To run the listener in the command prompt: factor.exe -run=listener * The Factor FAQ The Factor FAQ is available at <http://factorcode.org/faq.fhtml>. * Command line usage Factor supports a number of command line switches. To read command line usage documentation, enter the following in the UI listener: "command-line" about * Source organization The Factor source tree is organized as follows: build-support/ - scripts used for compiling Factor vm/ - sources for the Factor VM, written in C core/ - Factor core library basis/ - Factor basis library, compiler, tools extra/ - more libraries and applications fonts/ - TrueType fonts used by UI misc/ - editor modes, icons, etc unmaintained/ - unmaintained contributions, please help! * Community The Factor homepage is located at <http://factorcode.org/>. Factor developers meet in the #concatenative channel on the irc.freenode.net server. Drop by if you want to discuss anything related to Factor or language design in general.
