REBOL [ Title: "Rebol Reader" Date: 8-Mar-2006 Name: 'Rebol-Reader Version: 0.1.2 File: %rebol-reader.r Author: "R.v.d.Zee" Owner: "R.v.d.Zee" Rights: {Copyright (C) R.v.d.Zee 2006} Tabs: 4 Purpose: { The script is a method to provide an orderly collection of scripts and documents to form a Rebol reference. } Library: [ level: 'beginner platform: 'Windows type: 'tool domain: [GUI] tested-under: none support: none license: none see-also: none ] Notes: { Welcome To The Rebol Reader ! When first opened, the Rebol Reader doesn't appear to contain anything - except a list of Topics. The Rebol Reader is a book waiting to be written! The Rebol Reader is a both a method and a script. The Reader's intended purpose is to provide a means by which information may be gathered and created, reviewed and edited, and also transferred between documents. The Reader, with it's organised file structure of Topics and Titles, brings together the internet browser, a PDF reader, a text editor, the Rebol Web Blog, the Rebol/Core Manual, the Rebol Library and the many, many Rebol related Internet documents - and... the script writer. The Firefox Browser and the Adobe Acrobat Reader may be used with this script. These browsers may be resized and placed over this text area, at the top left of the screen. There they will function almost as if they were designed to be part the Rebol Reader. The Rebol Reader may make it easy to travel back and forth between related documents. Notes or scripts may be created or edited. Rebol scripts may also be launched from the Reader, so scripts may be developed, tested and edited. Getting Started First, scroll down the Topics and find "Rebol Reader". Select that and then "Welcome To The Rebol Reader" in the Titles text-list. This document will then reappear! Scroll the Topics text-list down to "Manual" and download the Rebol/Core manual. Dowloading the "Desktop Library" script and selecting and reviewing scripts is a good way to become familiar with the Reader. Save material using the Firefox browser into the Reader's Topics directory structure. Later, when that Topic is picked from the Reader's list, that page and other related titles may be found in the "Titles" text-list. Selecting the title enables it to be viewed again. Text and Rebol scripts may be displayed in the text area of the Rebol Reader. PDF files may be viewed with the Adobe Acrobat Reader. Parts of the reference documents may be copied and pasted into new or existing notes or scripts. Long File Names Long file names with spaces between words may make for informative titles which may improve the Rebol Reader's usability. There is no need to write a file suffix in the file name field, as the suffix will be provided by the script. File Back Up Copies of %.txt and %.r files may be made when they are read by the Reader. Copied files may be found by selecting the "Back Up" topic. These files may be deleted with the button "Delete Back Up". RebolCore Manual The Rebol/Core Manual's zip file may automatically download, unzip and be written into a subdirectory of the Manual topic. Library The Desktop Library may be downloaded with the Internet browser. From the Rebol Reader, go to the topic "Library" and click the title "Get Desktop Library". The download page will open in the web browser. From the browser, save the %library.r file into the "Topics" directory of the Rebol Reader. (Only the Topics directory!) Then click the title "Install Library". The Library will install and run. The Rebol Reader will also close at this point and will have to be opened again. These instructions will display again when the "Titles" topic is selected if no library scripts are downloaded. PDF Documents The Rebol Reader may also display PDF documents. The Acrobat Reader may also be resized to fit over the Reader's large black text area. The first time a PDF title is selected, a pop-up directory finder will appear. The directory home of the available PDF viewer must then be selected. Text Editor The Copy, Cut and Paste buttons of the editor are limited in their functions: - Text may not be pasted into highlighted areas. - Text may not be pasted to the end of existing text. - If the keyboard is used or the text scrolled, two attempts to use the edit buttons must be made! While they have their limitations, these edit buttons are useful. Please send a comment if you can suggest an improvement here. The Rebol keyboard text edit functions are more reliable: - "Control" & "C" keys: copy highlighted text - "Control" & "X" keys: cut highlighted text & write it to the clipboard - "Control" & "V" keys: paste text No Warranty This script has no warranty expressed or implied, nor is this script claimed to be suitable for any particular use.
