The current version, 1.5, was released on 16 July 1993. The first public
release of Trashmaster was Jan 23 1992.
WHY
===
I had always wanted to write something like this but until now, I couldnt
do it. Not that it was particularly easy to do, even under Workbench 2.0.
How I did it
************
The main problem is with getting finicky old Workbench to stay "in sync"
with the filing system.. IE, removing its icons when a file is deleted.
Thanks to a new function called `DeleteDiskObject()', it's possible to get
workbench to remove an icon. Unfortunately Workbench still is kinda
brain-dead... when you have it display ALL files, it spontaneously creates
icons in memory for files that dont have them... which results in
`DeleteDiskObject()' not working (no file on disk) and Workbench not
removeing the icon. The only solution I could come up with is to
`PutDiskObject()' and then delete this icon, which works more or less
pretty well. There are still, however, problems. Workbench, it seems,
will "lock" a directory if its window is open on the Workbench screen.
This means I can't delete it until it's closed... not too big a deal,
since when you delete the icon the window closes automaticaly. But what if
something *else* has that directory locked? Then I couldn't delete it
after all... that means I need to put the icon back! heheh. But I think
I've come up with a good solution.
Another problem is that there's no way to find out where the AppIcon is,
within the WorkBench window -- so there is no way to implement a snapshot
option within your application (of course, the root problem is that
Workbench doesn't provide any way to "hook" into the Workbench operations
like snapshot, info, etc. See below for my solution to this).
This seems like a good place to voice some opinions on Workbench 2.0, and
what I'd like to see in the future.
Wish list
Wish list
*********
* DiskObjects should be a BOOPSI class.
* A BOOPSI class would have methods for all the normal Workbench
operations; like info, double click, delete, snapshot, copy/move,
etc. That way, an AppIcon could give an "about" requester with
the info menu function, and behave in every way just like a
regular icon. Say you had an icon for a network machine... info
could put up a requester saying what the node's name was, CPU
class, whether it was Ethernet or serial, etc. neat huh? A
Drawer could open it's own type of list window.. perhaps one
with a "tree" display. You could replace the standard operation
with new ones (via hooks into the DiskObject class). This makes
Workbench extremely flexible and extendable and would allow third
party people to add tons of functionality to Workbench (I should
be able to make Workbench as powerfull as DiskMaster or DirOpus!)
* This BOOPSI icon would be able to have more than just a bitmap
image; like actual structured drawing objects. Of course, this
introduces the problem of how to store objects on disk.. which I
myself am working on.
* *Any* application would now be able to use icons easily (they
dont have to have anything to do with Workbench). You could even
drag icons *from* an application *to* a Workbench window to save
a file.
* Clipboard support, with a "view clipboard" window.
* Definable default tools for projects, with file recognition so it knows
what tool to run (in case there's no icon or the normal tool cant be
found). And how about a small database that contains application
names and then a path to where it is? Actualy, I guess you could have
a "Applications" directory, with icons that are linked to whereever
the app is -- and Workbench would check here first for tools.
* "Left out" icons could be done in the same way, so that the app's icon
is still visible in it's Drawer, and so that Snapshoting the left out
icon doesn't ruin it's original coordinates.
* Something needs to be done about the list windows.. they are slow and
clumsy, and are missing what I think is a great feature: a "Tree"
mode.
* Better tracking of when other apps change/add/delete files.
OK, I'll step down off my soapbox now!
Using Trashmaster
*****************
Usage
=====
To run Trashmaster, simply double click its icon, or run it from a CLI
(it will detach from the CLI of course). Obviously, Workbench must be
running (and will be, unless you were naughty and modified your
startup-sequence). Trashmaster will open an icon on the Workbench screen;
this icon will look the same as the icon you ran Trashmaster from. If you
want to change it, you can, by modifying the Tooltypes in Trashmaster's
icon (see below about the Tooltypes available). BTW, the icon is supposed
to look like a black hole...
If you want to be able to format disks with Trashmaster, you must have
`WBStart-Handler' installed in your `L:' directory. The WBStart-Handler is
included with ToolManager, a must-have utility, or in it's own separate
distribution, both of which should be available on a Fish disk or any good
FTP site, or failing that, from me. ToolManager and WBStart are Copyright
(C) 1991-93 Stefan Becker. The default formating program is the same as
Workbench's formatter.
To use Trashmaster, simply drag files and drop them on the icon. A
requester will come up, similar to Workbench's Delete confirmation
requester. If you really want to delete the file(s) or dir(s), click `OK';
if not, hit `CANCEL'. Remember, once you hit `OK', the files are deleted..
they're *gone*! For reals. Not like the Trashcan. If you have the
`VERIFY=OFF' tooltype set, you *won't* get this requester!
One difference from the Workbench Delete, is the extra option for
Interactive deletion. With interactive delete, you will get a confirmation
requester for each file you dropped into Trashmaster. For each file, you
can choose to either delete it, delete all the rest of the files
non-interactively, skip this file, or abort completely.
If Trashmaster comes across a file that is protected from deletion, it
will bring up a requester with two options, `FORCE' and `CANCEL'. If you
select `FORCE', Trashmaster will un-protect the file and delete it!
Selecting `CANCEL' will of course cancel the operation. If you have the
`FORCE=ON' tooltype set, you *won't* get this requester, the file will
simply be deleted without warning.
To quit Trashmaster (which you dont really want to do, do you? :),
double click the AppIcon and select the remove option.
If you want Trashmaster started automaticly (you DO, dont you?), place it
into the "WBStartup" drawer on your boot disk.
Tooltypes.
==========
There are 8 Tooltypes you can add/modify:
`X=<##>'
This is the X coordinate of the icon. A -1 will tell workbench to
find a suitable place for the icon.
`Y=<##>'
This is the Y cooridnate of the icon. A -1 will tell workbench to
find a suitable place for the icon.
`ICON=<name>'
This is the name of a custom icon to be used instead of the default
icon (the default being Trashmaster's icon)
`NAME=<name>'
Set this to change the name under Trashmaster's AppIcon.
`FORMATTER=<name>'
Set to the name of the disk-formatting program of your choice. The
program will be started as a Workbench application and passed the disk
icon to format.
`VERIFY=<ON|OFF>'
If set to `OFF', the initial verification requester will *not* appear.
If set to anything else, or not present, verify will default to `ON'.
The action performed will be the one defined by the `TYPE' tooltype.
Use at your own risk.
`TYPE=<INTERACTIVE>'
Applicable only when `VERIFY=OFF' is set. If set to `INTERACTIVE',
deletes will default to interactive deletes (requireing confirmation
for every file and directory).
`FORCE=<ON|OFF>'
If set to `ON', files that have their protection flags set to
delete-protected will be deleted without warning. If set to anything
else, or not present, you'll get a requester whenever you try to
delete a protected file.
`VERIFY', `TYPE' and `FORCE' can work in conjuction. If you don't want
*any* anoying verification requesters, you can turn `VERIFY' off, `TYPE' to
nothing (leave it out), and `FORCE' on. If you always want interactive
deletes, have `VERIFY' off but `TYPE' set to `INTERACTIVE'.
Be carefull with these! If you turn off verification and use the
`FORCE' option, anything that gets dropped on TrashMaster will be simply
deleted without warning, even if it's protected from deletion.
