- Strainer 0.8 by Paul R. Potts 11/8/93 11:25 a.m.
-
- description for online services:
-
- Strainer 0.8 is the latest release of the Strainer utility, adding
- several new features. Strainer is designed to let you easily
- mark and remove entries from your Newton's storage. This can
- help you to get around a bug in the Datebook which makes it
- difficult to delete certain entries, or to remove outdated entries
- in order to keep as much memory free as possible.
-
- New features in version 0.8:
- - You can now mark entries in multiple soups and strain them
- all at once.
- - I now handle straining of items on storage cards, if present.
- - Strainer now has dialogs to ask you what you want to do if
- you close the app before straining out the entries you have
- marked.
- - You can browse and mark entries in the to-do list and Names
- - I have fixed a bug in 0.7 that caused errors when trying to
- browse soups and no storage card was present.

- -----------------------------------------------------------
-
- The first version of Strainer that I released (0.3) was completed
- and sent to the net on my birthday, 9-26. I was happy to celebrate
- my 26th birthday by sending my first completed Newton application
- into the world. I hope to be able to provide many more useful
- and interesting programs in the future.
-
- Strainer is a utility that allows the user to browse through three
- Newton system soups, called Calendar, Calendar Notes, and Repeat
- Meetings. They can see old, obsolete, or incorrect entries, mark
- them for deletion, and delete them. Strainer is a little easier
- to use than walking around trying to delete everthing in the datebook,
- and it can also be used to get rid of entries in the datebook which
- can't be removed due to a few bugs in the Calendar. (Yes, PIE is
- aware of these bugs and they will be fixed in a future release).
- Users might want to use Strainer as a means of keeping as much
- memory free as possible; old datebook entries take up room in
- memory, so it makes sense to delete them if you really aren't going
- to be needing them any more.
-
- Strainer is written using the Newton Tool Kit, which I got at the
- Boston MacWorld Newton launch. I'm very new to Newton programming,
- like most developers, and so I'm very aware that, although strainer
- seems to work, there still may be lurking bugs. Also, I know that
- my NewtonScript code is very inefficient; in particular, I'm using
- a very inefficient search method in the browser. I have plans to
- speed this up greatly in the future. (It isn't your Newton that is
- so slow, it's my code). In a future release, I hope to have the code
- cleaned up and looking nice and to distribute the source code as
- an example for other Newton programmers who are trying to work with
- soups.

- VERSION INFORMATION
-
- Version 0.3:
-
- First release.
-
- Version 0.4:
-
- - actually included something in the READ ME FIRST file; in the
- 0.4, it went out blank because of a dumb mistake on my part.
-
- - fixed weird, hard-to-pin-down bug where checked items were
- becoming unchecked after walking back through a number of them.
- (this could result in the user being unable to change their minds
- and uncheck an item). The reason the bug was hard to find is that
- it was actually two bugs. When I fixed the first bug, the second
- bug was still active, making me think that my fix hadn't helped.
- The opposite thing happened when I fixed the second bug.
-
- - my views no longer float, so you can now bring up another window
- on top of them.
-
- - made some cosmetic improvements.
-
- Version 0.5 (not released):
-
- Made it possible to select items in multiple soups for straining.
-
- Added a test so that if we close Strainer with items selected, a dialog
- comes up asking you if you want to delete the items before closing or forget
- their marked-for-deletion status. Cleaned up organization of code a bit.
-
- version 0.6 (not released):
-
- Added support for straining the to-do list soups.
-
- Cleaned up the code a lot; reduced app size by removing redundant functions;
- now using simpler path expressions.
-
- version 0.7:
-
- I now use Union Soups so if you have a card in the slot with items on it,
- you can browse and delete those items along with ones on the internal store.
-
- version 0.8:
-
- Fixed a bug which caused an "array out of bound" (-48205) if you tried to
- browse with no memory card installed. Apparently most of the people
- using Strainer had cards installed, but I did get one report of this problem
- which helped me fix it.
-
- Rebuilt with NTK version 1.0b6, which is much nicer to use (speed of builds
- has been improved a great deal).
-
- NOTES ON USING STRAINER:
-
- - I do support union soups, but I'm not yet doing extensive checking,
- so there are some things that might cause problems: for example, don't
- yank out a card if you're browsing items on it; if you try to strain out
- items on a card that is write-protected, you'll probably get an error,
- since I don't check for that yet. I'll try to handle all the obvious
- conditions in a future release.
-
- - Close the datebook before starting Strainer; otherwise, if you
- strain out entries that are visible in the datebook, the datebook
- won't update its display until you close it an re-open it (technical
- reason: the datebook doesn't respond to the soupChanged message, so
- I don't bother to notify it).
-
- - If you find ink entries in your calendar soup, they aren't
- supposed to be there; remove them. Strainer will say <this
- entry is ink>. These entries are apparently in the soup because
- of a known bug in the Calendar.
-
- Things remaining to fix:
-
- I don't know of any real bugs remaining. There are a number of missing
- features:
-
- - I want to support faster browsing and deleting. Right now, I'm using a
- soup to keep track of marked entries; it would be faster to use and
- array, so I'll probably do this in the future. Also, my method of searching
- for marked entries is extremely inefficient. I'll speed this up in a future
- release.
-
- - Some of the features I'm thinking of adding: a cleaner interface, a method
- of seeing how many entries are in the soup and how far through them you are,
- and an Overview mode. However, I also want Strainer to remain a small
- application, which means not going overboard on features. If there's a
- particular change or feature you want to see, please let me know.
