R CHANGES UNDER CONSIDERATION (30 Jan 1978)
|
||
|
||
-- changes made ---
|
||
|
||
leading ^C, ^R causes break
|
||
don't remove trailing blanks in nofill mode
|
||
FS changes both c and p fonts
|
||
PF request removed
|
||
TR takes 2 characters only
|
||
WF and WA can take a full file name (if one name given then
|
||
taken as extension)
|
||
HV, VV requests
|
||
^F ring buffer (also used by FS)
|
||
FONT, PFONT NR do not affect ring buffer
|
||
Fwidth NR
|
||
End_of_sentence NR
|
||
|
||
-- likely changes --
|
||
|
||
Allow arb. space/tab to separate file name from font mode
|
||
Should the no-space mode be reset when the vertical position is
|
||
changed? (YES)
|
||
.ms <macro-name> <sr-name> macro -> string
|
||
CFDATE, CFTIME string registers
|
||
Does ^X macro start in state=0? Should it?
|
||
|
||
LESS LIKELY CHANGES
|
||
|
||
Concealed newlines?
|
||
Outfile SR/SR init?
|
||
case shift request?
|
||
Better way to handle tabs.
|
||
Allow underlining of white space (internal prefix operator).
|
||
A way to avoid widows?
|
||
RD arg should always go to tty (error file on UNIX?)
|
||
Should .nr font x interfere with ^F* (by changing old font)?
|
||
At least document it.
|
||
There apparently is some use for a "left-justify" character, other
|
||
than the hpos hack, which perhaps should change.
|
||
Could use a "relative tab" that does not break words or affect justification.
|
||
Perhaps simply change semantics of .hp to always be
|
||
relative (thus allow negative hpos until actually used).
|
||
\^A"0 "doubles" quotes before inserting
|
||
Should allow more than 10 macro arguments?
|
||
Think about beginning-of-line and end-of-line traps (for line numbering
|
||
and large character hacks)
|
||
Perhaps the ES request should not copy the partial line.
|
||
Recognize hyphen at end of input line in fill mode (?)
|
||
Invisible hyphen character ^Y (?)
|
||
LPT_TABs: if (n=lpt_tabs)>0 then assume that LPT has tab stops every
|
||
n columns and use tabs for input tabs, ^Ps, etc.
|
||
Should " matching only occur at one input level? How difficult to
|
||
implement?
|
||
|
||
Possible uses for remaining control characters:
|
||
^O - horizontal offset
|
||
^Y - hYphen
|
||
|
||
R BUGS
|
||
|
||
R MACRO BUGS
|
||
|
||
R MACROS
|
||
|
||
R MACRO DOCUMENTATION
|
||
|
||
R MANUAL
|
||
|
||
Ignore would be a good example.
|
||
Should talk about using fixed-width fonts to get things
|
||
lined up as in input (pf and tabs).
|
||
Explain how character width is calculated, and what it means.
|
||
space_width = width (' ')
|
||
char_width = max (width (' '), min (2*width(' '), width ('0')))
|
||
Note that skipping statement bodies knows nothing about
|
||
macro definitions.
|
||
EQ needs example.
|
||
Note that .\^Sfoo is possible.
