Factor/Examples

Examples

Here are a few of my favorite example programs.

Simple

• hello-world
• hello-unicode

Networking/web

• time-server - simple TCP/IP server
• webapps.calculator - simple webapp
• webapps.wiki - the source code to this wiki
• smtp - send e-mail via SMTP, with optional SSL support
• syndication - parse RSS and Atom feeds, write Atom feeds

Algorithms

• rot13 - rot13 "encryption"
• roman - convert numbers to and from roman numerals
• morse - convert strings to morse code and vice versa, and play morse code with OpenAL
• base64
• id3 - ID3 parser
• usa-cities - parse a CSV file and extract information
• benchmark.mandel - Mandelbrot fractal generator

Running the examples

Some of these demos define a MAIN: word. This means they are runnable from the Factor listener, by issuing a command such as the following,

"hello-unicode" run

Others are libraries, which means that after loading them with a command like,

USE: roman

you can then get a list of words,

"roman" about

and play around,

( scratchpad ) 123 >roman .
"cxxiii"
