Euclid Quick Start

This file is for those who just want to start up Euclid and start playing.
If you read this file and are good at "playing around" with programs, then
you could eventually learn almost everything about how to use the
application.
••••••••••
System setup:
If you plan on working on a large argument, then you should allocate at
least 1000K or memory for Euclid. You may do this by selecting the icon
for the program and choosing "Get Info" from the File menu in the Finder.
In a box labeled "Current size: " you can enter the amount of memory that
the program will use. If, while using the program, it complains about
being low on memory, then you should make the memory larger.
The program will run fastest from a hard disk, so you may copy it to your
hard disk drive instead of running it from a floppy disk. The program does
some safety precautions when saving files, so you should have at least
twice as much space on the disk than your data file holds. The program
makes an extra copy of the file while it is saving so that if the computer
crashes, you can still recover your data.
••••••••••
How to start:
Launch the app. You must have a database open before you can open a
display. If you open only a database, you will only see a smalltalk-like
view of the database. This is not very useful, but you can see what's
there in some form.
When you open a database, you will be asked to log in. If you haven't
logged in before, then create a new user and put your initials or some
short (<= 4 chars) identifier for yourself.
Only the user who creates things may edit them.
If you want to make some claims from your own perspective, then you should
define a primitive source for yourself. That means "I say…". If you want
to quote someone, or give another persons perspective, then create other
primitive sources for them. This means "That other person said…". If
another user already created the source that you want to use, then just
use that one.
After it is started up, you can set up the default types and default
source. Any new object you create will be given the default source and a
default type.
Open a display or create a new display for real work.
••••••••••
Things to know:
The first time you use a database, be sure to login as a new, unique,
user. If you use another users login name, and they also make changes,
then you and the other user could have problems merging databases. Login
sequence is to ensure that merges will always work.
You can't edit any object created by another user.
If you are collaborating, you can merge another persons database into
yours by using the Merge Database… command under File. This takes all
changes in another database and merges them into the currently open
database.
••••••••••
Things not in the menu bar: (VERY IMPORTANT THINGS!!!)
Double-clicking in the drag bar of any object brings up its info page for
it. You can change its type, source and name there. The name can be
anything to identify the object, but is optional. The default name of an
object is its text for text objects and its type for relation and list
objects. You can change the name by editing the default name. If you
erase the entire name, it will revert back to its default name.
To create a relation between two objects, hold the option key and drag
between two object. If neither end of the drag is a relation, then a new
relation is created between them. If either end is a relation, then only a
line will be created.
If you want to create a new relation, where either end is already a
relation, then create the relation first (cmd-R or in the object menu) and
then link it to its relatives with the option-drag.
The little box on one end of every relation shows which end of the line is
its "owner". The owner is always a relation, and it represents the
relation which the line is part of. This may sound confusing, but don't
worry about it too much. You can see an example of this in the manual.
If you want to "hand drag" (a la MacPaint) the contents of a display
window, hold the control key down, and a small hand cursor will show that
you can slide the picture around.
