Description: '
Date':  6 Apr 84 00':32 PST'
From': Sheil.pa'
Subject': New version of DEdit'
To': lispcore^'
cc': lispsupport, lispfriends^'
'
There is a new version of DEdit on {phylum}<lispcore>sources (and in future loadups).'
'
The major change is that DEdit''s internal data structures have been revised so that they take 1/3 less space.  This should radically improve swapping performance over extended programming sessions.'
'
A much requested feature': New function template. If one runs DF on either a name with no function defn (either real or spelling correctable) or with second arg NEW, i.e. DF FOO NEW, one is given a "blank" defn which will be installed on exit if any changes are made to it.'
'
In addition, many bugs have been fixed and much general sanitation and reworking of the internals has taken place. '
'
Enjoy.'

When using Control to batch commands, it''s possible to screw up the editmenu.'
I did point, point, point, typein, control down': replace, replace, control up, replace. After doing the 3 replaces, the replace menu item is still inverted!!'

'
...IF you pass through the "standard" editor (use editcoms) on the way to Dedit AND if you delete something in Dedit AND you exit while the deleted item is still selected in the type-in window, THEN Dedit will smash the defn of the function and replace it with the deleted (selected in the type-in window) S-expression'

'
if you have some expression that has multiple copies of an atom on it, e.g.'
    (BITBLT DS LEFT OLDBOTTOM LEFT DS LEFT  ...]'
and start a Find for LEFT, it will find the first LEFT in the line, but subsequent Find commmands just hang there and will not advance to later instances.'

if the cursor is "near" the top of the screen, then holding TAB down will snuggle the menu over to the cursor into such a position that some of it will be clipped off the screen.'

Not everything made it into this version. Over the next few days, I''ll be dumping my residual bugs into the AR system.'

AR 675 (font cache not cleared by FONTSET (I use Ron''s instead, thanks Ron));'
'
AR ?? (Mousing editbuffer during typin doesnt change tty process) (does now)'
'
AR ?? (Buried DEdit menu) (it now climbs to the top iff it is the TTY process);'
'
AR ?? (TAB/KEYACTION problem) (Pending a solution to the infamous PEEKC bug (waiting for which young children have grown old) I followed Bill''s advice and reset it with TTYENTRYFN and TTYEXITFN properties).'
