Download & Install

Version 3.0.11 is the current release.

Windows

Context Free 3.0.11 (v40) (5.2MB) for Windows Vista and later. The download file is an executable installer, just run it. This is a local installer that will install Context Free in your ApplicationData\Local folder. .NET Framework 4.5 is required to run Context Free. The installer will warn you if you don't have .NET 4.5. Windows should prompt you to download .NET 4.5 if you do not have it.

Support for generating QuickTime is now optional and bundled separately from the main installer. If you want to generate QuickTime movie output then you must download and install FFmpeg for Context Free (v3.3.1 32.6MB). The FFmpeg ffplay utility is used to preview QuickTime movies. This is a simple video player controlled by keystrokes. Instructions for controlling ffplay are here.

Windows Command-Line Version

The installer also installs a command-line version of Context Free, called ContextFreeCLI.exe. It is identical to the Unix command-line version, cfdg, except that it uses Windows/DOS command syntax:

ContextFreeCLI.exe /s400 /c input\mtree.cfdg output\mtree.png
        

instead of

cfdg -s400 -c input/mtree.cfdg output/mtree.png
        

Macintosh OS X

Context Free 3.0.11 (v43) (1.4MB) for Mac OS X 10.7 and later. Just copy the application from the disk image to your Applications folder. PowerPC and 32-bit x86 support has been dropped.

OS X Mountain Lion users (and later): This version of Context Free is signed. It should run with just the standard warning about content from the internet.

OS X Leopard & Snow Leopard users: This version only supports OS X 10.7 (Lion) or later.

Posix / Unix / BSD / Linux

Download the source code and build using make. You'll need a C++ compiler, flex (not lex), bison, and the libpng graphics library (not just runtime support, the whole developer package). Most of this should be installed or easily available on any modern operating system distribution. See the README.txt file in the source for build and run instructions:

ContextFree 3.0.11 gzip compressed tarball (v27) (3MB)

ContextFree 3.0.11 xz/LZMA2 compressed tarball (v27) (1.9MB)

ContextFree 3.0.11 compressed zip file (v27) (3.5MB)

The lastest developer release can be obtained from the Git repository at Github:
