#From: "Eirik Fuller" <wonton.tn.cornell.edu!eirik@ucsbcsl.UUCP>
|

#To: bfox@ai.mit.edu (Brian Fox)
|
||||
#Subject: Patch to bash 1.05 for SunView
|
||||
#
|
||||
#I think this works:
|
||||
#
|
||||
Mu|sun-cmd:am:bs:km:pt:li#34:co#80:cl=^L:ce=\E[K:cd=\E[J:rs=\E[s:
|
||||
#
|
||||
#Another alternative is to send the ti string at startup time (and, I
|
||||
#guess, the te string at exit time); that is how vi works in a cmdtool.
|
||||
#The best reason to not do this is that this also disables scrolling
|
||||
#which, as I understand it, is why anyone would use cmdtool in the
|
||||
#first place. Sending the ti string at startup time would do strange
|
||||
#things on other systems too; in xterm it would use the alternate
|
||||
#screen.
|
||||
#
|
||||
#The problem with cmdtool, in case that is less than obvious, is that
|
||||
#almost none of the capabilities advertised in /etc/termcap are enabled
|
||||
#while scrolling is enabled. It has other problems too, like being
|
||||
#part of an outdated proprietary windowing system, but there's probably
|
||||
#no need to dwell on that. In a sense, though, the sun-cmd termcap
|
||||
#entry doesn't lie about the capabilities; I think the termcap man page
|
||||
#does warn about some terminals having cursor motion capabilities only
|
||||
#in the "ti/te window".
|
||||
#
|
||||
#A general solution to this problem would require a termcap capability
|
||||
#which somehow tells which features are available outside of the ti/te
|
||||
#window. There is no such capability in termcap now, of course.
