Summary

The simple host for the Gfx stack is a tiny command line tool. The tool contains a rudimentary REPL, and is able to run an arbitrary number of files. All graphical output is in the form of png files.

Usage: gfx [--to-file /path/to/output.png] [--of-size 100x100] [<path...>]

##Parameters

  • --to-file <path>: Specifies an output location for any graphics described while the command line tool was running. This parameter is available both for files and the REPL.
  • --of-size <size>: A string of the format NxN specifying the size of the canvas that will be created before any code is run. The default value is 500x500. This parameter is available both for files and the REPL.
  • <path...>: Any number of paths may be specified. They are run in the order that they are specified in the tool's arguments. If no files are specified, the REPL is started.
