Reply-To: Levin
Cedar 3.1 is released.
This release incorporates bug fixes in a small number of components and
includes one new component. No public interfaces have changed, so client
programs need not be rebuilt.
This release is stored exclusively on subdirectories of [Indigo]<Cedar>. Other
directories (e.g., CedarLang, CedarLib) are NOT part of the release and their
contents should be treated with suspicion. In general, users should access release
components using BringOver and the appropriate DF files; retrieving files with
the FileTool is likely to lead to version mismatches and confusion. For this
release, all top-level DF files for release components that users are likely to need
are stored on [Indigo]<Cedar>Top>.
Installation Procedure
---------------------
This release does not require new microcode for either Dorados or Dolphins.
There are new Cedar boot files, but no new CoPilot boot files (i.e., the CoPilot
boot files from Cedar 3.0 are suitable for use with this release). To install the
Cedar boot files, follow these instructions:
1) Get to Othello, either on the Othello volume or from the NetExec.
2) Fetch [Indigo]<Cedar>Top>CedarDorado.boot or CedarD0.boot to the Client
volume.
3) Boot the Client volume. No switches are necessary.
As with previous releases, once the automatic installation procedure completes,
you may then optionally acquire lots of additional useful files by typing
BringOver /a CedarClientFat.df (Note: NOT /p)
to the UserExec. This will fetch the exported contents of most of the major
packages, whether released as part of the boot file or as separate BCDs. Users
with limited disk space probably shouldn't do this.
Once you have brought over all the desired files, you may wish to make a
checkpoint, using the button at the top of the screen.
Known Problems
----------------
The following problems/glitches are known to exist in Cedar 3.1. (This list is
courtesy of Mark Brown and makes no claim to completeness.)
1. The UserExec copy command seems to report the low half of the number of
bytes copied. It does seem to copy all of the bytes correctly, however.
2. The UserExec command "old foo" does not open file foo (it will open foo.mesa
if it exists). This is not a problem for a file name with an extension, e.g. "old
foo.tioga" works fine. The command "new foo" will open foo. A Store to "foo"
will produce a file called "foo.mesa".
3. The spelling correction problems observed in Cedar 3.0 have not been fixed; as
a result, spelling correction is disabled by default. To turn it on, add
"SpellingCorrectionEnabled: TRUE" to your profile. Complex compiler command
lines (such as "compile a ← b[c: d, e: f]") do not work if they contain blanks.
The command "delete *.mesa$" is 'corrected' into "delete *.mesa". ESC-completion
for command names is observed not to work (though this may be coupled to the
disabling of spelling correction). When it does "work", it has been observed to
do undesirable things, e.g., it always leaves off the first char when there is no
space after "←".
4. FTP.bcd does not work in the UserExec. Its future is unclear (in the
meantime, use Bringover or the FileTool instead).
5. Plot viewers can't be destroyed.
6. Don't take a checkpoint with a mutable file (a file you intend to edit) in a
viewer. If edit this file and rollback, you'll have to bug "Reset" to see the edits.
This is true even if the viewer is iconic during the checkpoint.
7. Changes in RegisteredCommands.profile are not noticed by the UserExec until
you boot; rolling back is not enough.
8. Both scrollbars and buttons have the property that if you move the cursor
OUT of one with a button depressed, the scrollbar or button will not repaint.
Moving the curson IN will cause a repaint.
9. Print will break if you type a very long file name to it. Since Print will not
do remote file retrieval, there is no point in typing a full path name to Print.

This is a new component for Cedar 3.1.
[Ivy]<Laurel>Maintain.press gives a general description of the Maintain teletype
interface. [Indigo]<Grapevine>Docs>Interface.press describes what the Grapevine
database is about. The DF file exports Maintain.bcd; running it registers the
command "Maintain" with the UserExec; invoking that command creates a
typescript viewer implementing the boring old teletype interface. Don't use the
"Destroy" button: use Maintain's "Quit" command instead. The "Destroy" button
doesn't cleanup properly yet.

RegisteredCommands.profile now includes more common entries. There is also a
new program called MiscCommands.bcd that implements three commands: Version
(types Cedar version number), User (types user name), and Date (types day and
time).
Viewers and Tioga
------------------
DF file: [Indigo]<Cedar>Top>ViewersAndTioga.df
Documentation: Tioga documentation on [Indigo]<Tioga>Documentation>.
Contact implementors for additional information.
Implementors: TiogaImplementors↑.pa
(This component contains: TIP, Viewers, Tioga, Clock, Watch, VBoot, TSetter,
EditTool, EditHistoryTool, End, JaM, and JaMGraphics.)
Tioga and Viewers have no public interface changes and few new features; this
was largely a maintenance release. The editing and repaint code has been vastly
improved, so users should feel free to experiment with the node-structure editing
commands as described in the documentation. Performance has been improved
for editing and display of files. Dolphin users should notice less flicker and
faster updates.
There are a number of minor bugs relating to interactions between the caret and
the scroll-bar feedback; these are merely cosmetic and will go away in Cedar 3.2.
