Introduction
You can customise the way in which PipeDream 4 operates through two
different mechanisms. Nearly all document production packages have two
such mechanisms. In PipeDream 4 the first set of custom features is
available through the Choices menu (in some other packages this is
called Preferences) and these choices affect the way in which PipeDream
operates with all documents. The second mechanism allows you to create
separate proforma for different types of documents; in PipeDream (and
Fireworkz) this second mechanism is the facility to create a large
range of Templates.
You will find an article on templates in the directory Templates1. I
suggest that you read the article in this directory first and follow
that by reading the article in the Templates1 directory.
Getting Started
Install PipeDream on the icon bar, place the pointer over the icon and
click the mouse menu (middle) button. The pop-up menu which appears
has five items one of which is Choices and, just below Choices is the
Save Choices option. If you run the pointer through Choices the
Choices pop-up menu will appear. You can now change any (or all) of
the features appearing on this Choices menu.
Finishing
Yes! I know we haven't done much yet but it's always as well to know
where we're going to finish up otherwise we might not get there! When
you have made your choices from the Choices menu you can click the
select (left) mouse button on Save Choices and, from now on, whenever
PipeDream 4 is loaded to the icon bar your choices will be applied to
the way in which PipeDream operates with every document.
The Choices File
Have a look in the !PipeDream directory. By the way, to open a
directory which starts with a ! (what Acorn call an Application and
what I think should be called a package) you must hold down the <Shift>
key as you double click (the select button) on it.
In the !PipeDream directory you'll find a file called [Choices] having
a PipeDream filetype. If you double click on it it will simply load
into PipeDream and you'll be no better off. To see what's inside it
you need to hold down the <Shift> key and then double click. The file
will load into Edit and you will see a file containing perhaps a couple
of dozen rows each starting with a %PC% character.
Unless you want to do something very special you probably don't need to
know what these cryptic %PC% so called 'constructs' mean. If you do need
to know then you can do some research by looking at the section headed
PipeDream File Format which starts on page 197 of the PipeDream 4
Reference Guide. Pages 199 to 201 contain a brief description of each
of the %PC% constructs.
Hidden Choices
Perhaps you might have noticed that there are some constructs which
appear in your [Choices] file which are not available from the Choices
menu. An example in my own [Choices] file I find the construct
%PC%OP%PC%PDHPJet. This construct is in two parts, %PC%OP%PC%PD followed by HPJet.
The PD refers to the choice of (PipeDream) printer driver; in my case
HPJet is my default choice. Those constructs which are not available
from the Choices menu are derived from whatever document is the
currently selected document (the PipeDream document which is on screen)
at the time when the Choices were saved.
If you've followed me this far then you'll realise that the [Choices]
file contains information derived from two sources namely the Choices
menu and a typical document.
The Choices Menu
Have another look at the Choices menu. My own choice of Choices is to
turn on all the following: Short menus, Auto check, Auto recalc (short
for Auto recalculation), Auto chart update and Insert. I leave the
Colours as their default but I do set the Paste depth at 50 instead of
the default value of 10.
If you run your pointer through Dictionaries you may not have any
opened! I have four. These are the Master dictionary and three other
specialist dictionaries. You can not choose which of your dictionaries
are opened from the Choices menu! Read on.
The Default Document
Click the mouse Select (left) button on the installed (on the icon bar)
PipeDream icon and a blank document will open. In the correspondence I
receive from you I've been asked all too often how PipeDream selects
the template (implying that it's from your !PipeDream.Templates
directory) which is displayed when you click Select. The short answer
is "None of them"! The longer answer is that the file which is loaded
is [!PipeDream.Choices] complete with all the choices it contains.
Similarly, if you drag a file having a Text format (such as the
[0thReadMe] file from this disc) or a CSV file onto the PipeDream icon
then the file will be loaded by PipeDream into this default document.
If you often drag Text or CSV files into PipeDream this way then giving
some thought to your [Choices] (default) document will be worthwhile.
You can make changes to the [Choices] file and then save the file in
the usual way (not recommended) or you can make your changes to
[Choices] and then, from the Choices menu click on the Save choices
option (better). In the first case the [Choices] file will be saved
with most, but not all, of the changes embodied in it; if you use the
Save choices method then you can be sure that all your choices will be
saved in [Choices].
Here is a simple exercise which you might find interesting if you've
never seen it done before. Place the pointer in the directory
containing the [Choices] file, click the Menu button, run the pointer
through Display and click on Full info. You will see displayed the
time and date at which [Choices] was last saved. Click the Menu button
on the installed PipeDream icon and then click Select on the Save
choices option. You will see the time/date stamp of the file [Choices]
change as the new version is saved. Whoops! What was the currently
selected document at the time you clicked on Save choices?
Options
Load the [Choices] file into PipeDream by clicking on the installed
PipeDream icon (or by double clicking on the [Choices] file). Execute
the command <Ctrl O> to bring up the Options menu. Now make your
changes. I rarely use this 'template' for anything but Text files so
my selection is:
%L%No title
%L%Because I usually use this 'template' for text I select
%L%New slot format: Text
%L%Insert on wrap: Row
%L%Borders: On
%L%Because I use the System font for my default document I select
%L%Justify: Off
%L%Because I want <Delete> to cause a paragraph to reformat I select
%L%Wrap: On
%L%Decimal places: 0
%L%Negative numbers: Minus
%L%Thousands separator: none
%L%Because I want <Delete> to cause a paragraph to reformat I select
%L%Insert on Return: On
%L%Date format: Text
%L%Leading characters: £
%L%Trailing Characters: %PC%
%L%Grid: Off
You may have different requirements from me and so you may choose a
different set of Options. If you do need a variety of default
documents then you should use templates for the variants rather than
attempt to use a variety of [Choices] file. You will find examples of
using templates this way in the Templates1 directory on this disc.
Columns
You can save a column structure as part of [Choices]. My selection is
that I have only one column, Column A, which has a width of 12
characters (set with <Ctrl W>), and a wrap width (set with <Ctrl H>) of
72 characters.
Decimal Places
The command <Ctrl LDP> can be set to a default which is different from
the number of decimal places set from the Options menu. I set my
<Ctrl LDP> to 2 decimal places - my <Ctrl O> decimal places is zero.
Printing Options
%L%You can save in your [Choices] file:
%L%(a) the Page layout accessed through <Ctrl PY>
%L%(b) the Printer configuration accessed through <Ctrl PD>
%L%(c) the Font accessed through <Ctrl PFG>
(d) the Print menu accessed through <Ctrl PO>.
I have chosen the System font and a suitable PipeDream printer driver
(Parallel and HPJet). Because I am using the PipeDream printer driver
(with the System font) I set the page length to zero and I set the
printer to print only one copy to the Printer (rather than to a file).
Dictionaries
Through the <Ctrl SO> command you can open those user dictionaries you
want loaded by default. I have loaded three of mine. I think that
there is a limit of five but I've not tried it recently so I'm not sure
whether this includes Master or not. I believe that the facility to
load your user dictionaries as PipeDream loads to the icon bar is one
of the most useful features of [Choices]. I have had a lot of trouble
trying to find the documentation for this feature so, if you can find
it, then please let me know where it is!
By the way, you need to Create a user dictionary before you can open
it. You can not use it until it is opened!
The option to Lock dictionaries is nothing to do with making
dictionaries Read only. If you Lock a dictionary then you load it into
memory (RAM) rather than use it from the disc. Since most people these
days use PipeDream from a hard disc (rather than a floppy) it is
probably better to not Lock your dictionaries. If you are still using
relatively slow floppies for the PipeDream program (not the data files)
then there may be some merit in loading the dictionaries into memory
(if you have enough memory).
Finally, you need to Save choices from the icon bar (ie not by saving
the [Choices] file) if you want to include user dictionaries as part of
your start up choices. If you save the [Choices] file then the
instruction to Open the dictionaries will not be executed.
In Conclusion
I have spent perhaps too much time discussing what is contained within
the [Choices] file. Remember that, just because an option is stored
within [Choices] that does not necessarily mean that every document
will be configured to that option.
The choices which do apply to every document are those which appear in
the Choices menu, accessed from the PipeDream icon (on the icon bar)
with the menu button. These are what might be referred to as 'global'
choices. The other choices which appear in [Choices] apply only to the
default PipeDream file loaded by clicking select on the PipeDream icon
or loaded by dragging Text or CSV files (amongst other types of file)
to the PipeDream icon. These are what might be referred to as 'local'
choices and are the subject of the article in the Templates1 directory.
I am not sure if 'Opened dictionaries' is really an exception to the
rule stated in the above paragraph. From the Pipedream Choices menu
you can not choose what dictionaries are opened as PipeDream is
installed. Although you can choose these only from your default
document, the choice is shown through the Choices - Dictionaries menu.
If you need a wider range of 'local' file configurations than can be
achieved with only the one [Choices] document, then you need to learn
about templates. There is an article about templates in the Templates1
directory. I suggest that you might read that next.
I believe that I have covered everything which can be stored in the
default [Choices] file (for use in just the [Choices] template or for
every document) but it is possible that I have missed something. If I
have missed something then please let me know and I'll mention it on
the next PipeLine disc. If you believe that it would be useful to
explain in more depth any particular choice of start up options then
please let me know and please include a copy of your [Choices] file.
