REBOL in a NutshellREBOLTM is the Relative Expression-Based Object Language designed over a decade by Carl Sassenrath, the software architect responsible for the highly acclaimed Amiga OS -- one of the world's first personal computer multitasking operating systems. REBOL is a messaging language that provides a broad range of practical solutions to the daily challenges of Internet computing. While designed to be simple and productive for novices, the language extends a new dimension of power to even the most seasoned of professionals. REBOL offers a significant new approach to the seamless exchange and interpretation of network-based information over a wide variety of computing platforms. If you've written HTML or shell scripts within a text editor, chances are you can write REBOL messages. A message can be as simple as a single line or as complex as an entire application. Here are a few short examples to give you quick sense of the language. If you want to print the traditional text message: print "Hello World!" Or you could send that text as an email message to a friend: send luke@rebol.com "Hello World!" To run a script which is stored on a web site: do http://www.rebol.com/library/beer.r And you can do the same for FTP (the file transfer protocol): do ftp://www.rebol.com/hello.r Perhaps you want to read a web page and save it as a file: page: read http://www.cnet.com write %cnet.html page Or you could just write the line: write %cnet.html read http://www.cnet.com To send a web page to a friend through email: send luke@rebol.com read http://www.cnet.com To examine your email messages without removing it from the server: print read pop://luke:r2d2@rebol.com Then, to delete all the email from your server that contains the word "vader":
If you need to email all the files in your letters directory to another friend: files: read %letters/ foreach file files [send luke@rebol.com read file] But, if you want to join all those files into a single message and send it: message: copy "" foreach file files [append message read file] send luke@rebol.com message When you are ready to send a message to your broker which is automatically processed by her REBOL-based stock trading application::
Of course, your boss wants you to automatically email several web pages every hour:
You need to extract and print the title of a web page: page: read http://www.cnet.com parse page [thru <title> copy title to </title>] print title Finally, you want to get help about a built-in REBOL word: help power You get the idea! Communicating with others has never been easier. Visit our script library for more applications and examples.
