REBOL [ Title: "using dict protocol from" Date: 17-Jul-2007 File: %dict-demo.r Author: "Brian Tiffin" Comment: "Based on work by Jeff Kreis" Purpose: {Some usage words for dict:// protocol based on RFC2229} Version: 0.9.3 Rights: "Copyright (c) 2007 Brian Tiffin" History: [ 0.9.0 17-Jul-2007 btiffin "First cut - mistakes non-zero probable" 0.9.1 17-Jul-2007 btiffin "Added demo, inclusion may be overkill" 0.9.2 18-Jul-2007 btiffin "moved demo out of scheme, lean mean" 0.9.3 27-Feb-2008 btiffin "corrected soundex and regexp arg handler" ] Library: [ level: 'advanced platform: 'all type: [demo how-to tool] domain: [text-processing scheme] tested-under: [ view and core and Debian GNU/Linux 4.0 ] support: none license: 'MIT see-also: {} ] Usage: { The url scheme defined in RFC2229 is: dict://<user>;<auth>@<host>:<port>/d:<word>:<database> dict://<user>;<auth>@<host>:<port>/m:<word>:<database>:<strat> For instance: read dict:// returns definitions of "rebel" or: read dict:// returns words that may match "reb", in the same manner as a spell-checker. Other strategies can be specified. See the RFC for details, or use strat: as the query type for a list. read dict:// returns the available databases. This port handler will also accept urls of this form: read dict:// which will return definitions for the word in question. Some port handler "extensions" from the RFC This handler is coded to return a block! of string! or a block! of blocks for definitions Also: default host is set to, See read dict:///d:word or read dict:///define:word for definitions read dict:///m:word or read dict:///match:word for matches and translations read dict:///help: will return a block of help read dict:///strat: will return the strategies for read dict:///info:db for database source and copyright info read dict:///server: system administrator server information read dict:///status: server status and timings without the colon, they are just words for definition Demo: To try out the samples, instead of just do %dict-scheme.r Use dict: do %dict-scheme.r as the information hiding context is returned by do. Then you can evaluate dict/demo } ] comment { This code is based on the work of Jeff Kreis, held at Jeff has coded his handler for direct port access, didn't work properly under REBOL [ Title: "REBOL dict Protocol $Revision: 1.0 $" Date: 19-Aug-1999 File: %dict.r Author: "Jeff Kreis" Email: %jeff--rebol--com Purpose: { Implements the dict protocol as per RFC2229.
