The Cedar Whiteboards June 22, 1985
Getting started using the Cedar whiteboards
The Cedar whiteboards are stored on the Alpine server Edelweiss.alpine; the command Whiteboard <SomeWhiteBoardName> will load the whiteboards code (if not already loaded) and open the names whiteboard. The current collection of Cedar whiteboards include:
cedar -- the root of the whiteboard database
Basics -- a collection of basic information about Cedar (like user profile information, how to use a command tool, how to boot a Dorado)
Language -- the Cedar language syntax, the language overview, style information and examples. There's also Spreitzer's MISP interpreter to show a different language in Cedar.
Components -- some of the more frequently used components. Each of these has its own whiteboard; they include:
Viewers -- all of the important viewers interfaces are there
Tioga -- this one could probably use some updating
CommandTool -- structure and use
Cypress -- with information about both Cypress and Alpine
Tools -- Walnut, DFtool (and DF files), EditTool, etc.
Interfaces -- right now, just Viewers, IO, and Rope
ToolBox -- this is one of the ones with sizzle. A collection of commonly used Cedar tools: middle-click then and they get loaded (some of them do take a little time to get started, so you might want to preload the tools you intend to use!)
Games -- references are made to Tank and Football, which haven't made it to Cedar6 yet! But you can show MazeWar and VBounce off.
CedarMail -- a whiteboard containing message set icons that refer to a little Walnut database I hacked together. First, click the Walnut icon to get things started, then browse the messages sets. The important thing to get across here is that Whiteboards and Walnut reside in different databases -- in fact, if you're using Walnut and Whiteboards together there are at least six different files in the act (all carefully hidden from the users view!)
What to Show Off
Aside from middle-clicking icons to open them, there are a few other cute things you can do with whiteboard:
1. CTRL-MIDDLE on a whiteboard icon "expands" it, showing all of the whiteboards that are on it (so you can see the entire whiteboard graph from where you happen to be) -- give it a try. You might want to do this on a relatively uncluttered whiteboard.
2. SHIFT-LEFT makes a new text box on a whiteboard -- fill it with some fancy Tioga stuff!
3. Holding down LEFT moves the nearest viewer (until you let up). Don't do this to a real big text -- this code needs some work! Icons zip right around.
4. Do an AddSelected through the menu line. Select some viewer (e.g., a Tioga document) and click AddSelected; then move the icon to its final resting place. This also works with most tools -- to make sure, try to add a tool that has come from a whiteboard in the first place!
