1. An introduction
==================
This program was written to complement one of my other utilities,
PowerPacker (a command and data cruncher). It is used to read normal ascii
text files or text files crunched with PowerPacker. The program itself is
about 10K long and when you know you save about 60% when you crunch a text
file, you can see that this could save a lot of space on your disks.
PPMore was written as a more replacement (as you could have guessed :-),
so I tried to keep the keyboard commands the same as well as adding some new.
There are two main differences between PPMore and More, PPMore uses gadgets
and it always loads the complete file in memory (More only loads part of the
file and will load the rest when needed). If you can live with these
differences, you can replace More with PPMore anywhere you want.
If you haven't got PowerPacker you are of course missing the main
feature of this program. You can try to find it in your favourite public
domain library or you can get it by writing to my address and adding $15 US
(if you live in Europe), $20 US (if you live elsewhere). Send money in
cash (bit risky though), by international money order or by EuroCheck (only
in Belgian Francs (BF) !!!!) (Please don't send other checks). PowerPacker
was published in the November 89 issue of JumpDisk and can be found on one of
the Antares RD or Fish disks.
2. Usage
========
PPMore can be used in three different ways.
- First of all via the CLI:
If you enter PPMore without arguments you will get a usage template.
You use PPMore like this:
PPMore [<options>] <filename>
The program will then load the ascii file and display it. If the file
was crunched using PowerPacker 2.0 or higher PPMore will first decrunch it
for you. If the file was encrypted you will be prompted for the password.
The options are explained in section 4.
PPMore can be made resident so it doesn't have to be loaded every time
you use it, use the ARP ARes command or the WB1.3 Resident command for this.
You can't make PPMore resident when it is crunched !! The file is supplied
as an uncrunched command file with the pure bit set.
If you enter PPMore without options, you will be presented with either a
file prompt or the ARP filerequester (if arp.library is available).
Enter 'PPMore ?' for a little usage message.
- Via the WorkBench:
There are three different ways of using PPMore via the workbench: you
can set the default tool of the (crunched) text file to 'PPMore', you can
single click the PPMore icon and then double click the text file icon or you
can double-click the PPMore icon and enter the filename in the string gadget
(or the ARP filerequester) you will be presented with.
You set the default tool by single clicking the icon of the text file
and selecting 'Info' from the workbench menu. You will get a window with
several gadgets in it, click in the string gadget where it says 'Default
tool' and enter ':ppmore'. PPMore should be in the root directory of your
disk for this to work, if e.g. it's in the system directory you should enter
':system/ppmore'. Last of all select the 'Save' gadget.
NOTE: - PPMore will add '.pp' to the filename when the file wasn't found.
This is very useful in the WorkBench enviroment: you can make an
icon for 'text.doc' but name the file 'text.doc.pp'. Now the
WorkBench will show an icon with 'text.doc' as name, but if you
doubleclick it 'text.doc.pp' will be displayed. (As long as there
is no 'text.doc' file in the directory !)
- Once you are in PPMore press 'L' to load a new file, this is
especially useful if the arp.library is available.
3. Control
==========
PPMore can be controlled by keyboard or by intuition gadgets. To get a
summary of the keyboard commands press <HELP>, the function of the gadgets
shouldn't be hard to understand.
A few notes on printing:
- The printer.device has to be in the devs: directory for PPMore to be able
to print, you should also have a correct system-configuration for your
printer.
- You can continue to read the text when PPMore is printing (this IS a
multitasking computer ! :-), you can't quit when printing is still in
progress !
4. Using PPMore from other programs
===================================
If you are not a programmer you can skip this section.
PPMore 1.5 has two power options to make it possible to use PPMore from
other programs. This way you don't have to include a text displayer in
your programs, you just execute PPMore with one (or all) of the following
options:
-@mem,len,flags[,name]
If you specify this option PPMore will not load a file but instead it
will display a chunk of memory. You specify the memory addres and
length in the command line as well as some flags. The current version
only has one flag: PPMORE_FREEMEM = bit 0 of the flag-word = 0x1.
When this flag is set PPMore will free the memory after it has
finished, if it isn't set PPMore will just exit and leave the memory
alone. This way your program can start PPMore with the PPMORE_FREEMEM
flag set and exit before PPMore has ended. PPMore will then free the
memory instead of your program.
The address, length and flags must be presented as HEX longwords
seperated by a comma. These options can be followed by another comma
and a string to give the memory chunk a name, if this string is omited
PPMore will use the name 'memory'. This string ends with the end of the
command line so it can contain spaces.
-Sscreen or -S*
With this option you can use PPMore on another screen. You must
provide a screen address in HEX. PPMore will the open the main window
on this screen. If you specify a '*' instead of a screen address the
frontmost screen will be used.
Examples:
o PPMore -@1A000,1D4E,0,my chunk
PPMore will open a window 'Listing of my chunk', start
displaying at address 0x1A000 and stop at address 0x1BD4E. The
memory will not be freed after PPMore exits.
o PPMore -Sc2d8a0 -@1A000,1D4E,1,my chunk
Same as previous but now PPMore will free the memory chunk and
open the main window on the custom screen with the screen structure
on address 0xc2d8a0.
o PPMore -S* myfile
Load and display the file 'myfile' and open window on the front
screen.
NOTE: - The options are case sensitive.
- The @ option must always be the last option on the command line.
- If you open PPMore on another screen PPMore will not check if the
screen closes !! PPMore should always finish before this screen is
closed !
- I advise you to use the ARP 1.3 SyncRun and/or ASyncRun instead of
the AmigaDOS Execute function to execute PPMore from your programs
because the ARP functions also work when your program has been
started from WorkBench.
- Watch out when using this options, it is very easy to crash the Amiga
when you don't know what you are doing !!!
As always, I hope you find this program useful !
PROGRAM HISTORY:
*****************************************************************************
VERSION 1.0
First release.
*****************************************************************************
VERSION 1.1
'.pp' suffix added to filename when file not found, very useful in
WorkBench enviroment.
PPMore now also loads encrypted files. (PowerPacker 2.3a or higher)
*****************************************************************************
VERSION 1.2
Rewritten some routines in assembler, results in a slightly faster
and smaller PPMore.
Keyboard input improved. Autorepeat of keys is ignored so you can keep
on pressing <page down> without typing it 20 times ahead !
Gadget input also improved, now handles repeat.
PPMore now prompts for a filename when double-clicked from WorkBench.
*****************************************************************************
VERSION 1.3
PPMore can now be made resident and is reentrant. (provided PPMore is
not crunched)
Improved error reporting, the main window only opens when PPMore is
going to display the file.
File is checked to see if it is an ASCII (text) file.
Two new power-options for use of PPMore from other programs:
-@ to display memory, -S to open window on a custom screen.
Fast assembler search function added.
Display position is displayed in titlebar (percentage).
Goto n% function added, replaced 'Refresh' gadget with this function.
Decrunching is 15% faster.
'Exit PPMore' only selected when button is released on top of gadget.
NO bugs removed because none where found. :-)
Only about 700 bytes larger than version 1.2 !
*****************************************************************************
VERSION 1.4
Bug fixed: PPMore 1.3 was not 100% pure, version 1.4 is !
ASCII check less strict (e.g. now allows files to contain a '©')
Another 300 bytes shorter than version 1.3 :-)
*****************************************************************************
VERSION 1.5
Bug fixed: search/goto window always opened on WorkBench screen.
Find previous also implemented.
Load a new file from within PPMore.
PPMore uses ARP file requester if arp.library is available.
Line count, as well as goto line.
Display position as percentage or line number.
Keypad = movement. (for PC-lovers, yek :-( )
PPMore now supports all keymaps !! I think especially german and french
Amiga users will be grateful for this.
Less than 600 bytes longer than version 1.4 (I love this :-D)
