REBOL [ Title: "The rugby mobile code console" Date: 22-Aug-2001/14:14:44+2:00 Version: 1.0.0 File: %rugby-console.r Author: "maarten koopmans" Purpose: "A P2P console for Rebol/Rugby" Comment: { An example of a very simple console emulator that integrates with a rugby server. Original console emulator by Jeff Kreis on the mailing list. No fancy stuff such as auto-complete, arrows, or tabs (all throw errors). The console is started with the rugby server that exposes one function 'do-block. This allows remote execution on a running console! You can add functions and remove functions with expose-function and hide-function. Exposed? gives a list of all currently exposed functions. restrict-to restricts acces to a given block of IP numbers no-restrict drops all restrictions. refresh-stubs regenerates the stubs that other clients can import. Don't forget to call this after expose-function o hide-function Type ? for any of these commands to get a more detailed overview. } Email: %m--koopmans2--chello--nl TODO: { - Add a real console emulator!
