< Subject: bug in 3.6 vi (probably 3.7 also) < < Description: < Vi has a bug in it when the ^^ (control ^) command is used if the < current file has been modified and there was no previous file edited < and vi set for autowrite. < ... < When, under the above circumstances, this key is hit, the current file < will be written out, the error message of "No filename substitute for #" < will be displayed, then the last line of the file will REPLACE the < current line the cursor is on. If at this point the ^^ key is < accidently hit again, the file, now with a bogus line, will be written < out again. I just checked my beta-version of 3.10 Vi (the version going into UNIX System Vr3) and the bug still exists. Maybe it'll get fixed for Vr4. Tony Hansen ihnp4!pegasus!hansen

I posted this once before but I think it did not make it out of the local machine. Apologies if you have seen this already ... This is not the correct way to fix it, but a forbid(altfile[0] == 0); under `case CTRL(^)' in ex_vmain.c would get around the problem. -- In-Real-Life: Chris Torek, Univ of MD Comp Sci Dept (+1 301 454 4251) UUCP: seismo!umcp-cs!chris CSNet: chris@umcp-cs ARPA: chris@mimsy.umd.edu

This bug seems to be just an instance of a problem in the error printing code. Here are two known ways of making this kind of problem happen: 1. vi nonexistentfile ahi there david ews^[--wcw^[u^^ (^[ is escape, ^^ is control-^) The first line becomes the same as the last line. 2. vi nonexistentfile Alternately hit the interrupt and escape keys ten or fifteen times. Then, type ^L to redraw the screen. The first line of the file is now the word "Interrupt". David Elliott

I don't know if anyone in the mists of time has noticed and reported this feature before, but there is a serious bug in the line folding stuff when wrapmargin is non-zero. Repeat-by: Set wrapmargin=10. Create yourself a small file with the same line copied 3 or 4 times with each line just shorter than where the line break would occur. Go to the last word on line 1. Add in some text to cause a line split. Got to the last word on line 2. Type '.' to repeat the insert. Observe Fix-by: Don't know...I haven't the time to look just now. -- -------- Nick Stoughton nick@inset.co.uk Hit it with a hammer -- sure to work then! nick@inset.UUCP ...!ukc!inset!nick

I tried the "repeat-by" steps with my vi and had the same thing occur (I guess, Nick just says "Observe", and I assume that what I saw is what he meant). For the record, I have a Tandy Model 16 using XENIX/68000 3.0; the version of vi is 3.7. -Paul -- Paul Sutcliffe, Jr. UUCP: {seismo,ihnp4,allegra,rutgers}!cbmvax!devon!paul Devon Computer Services COMPUSERVE: 76176,502 Allentown, Penna.
