Hello,
I have defined the PS1 variable as follow
PS1='\[\e]0;\w\a\]\[\e[32m\]\u@\h \[\e[35m\]\w\[\e[0m\]\n\$ '
so that the cur dir is set as title of the window.
This generally work for both mintty or cmd.
But after the sequence
Luc@Mulan ~
$ emacs &
[1] 371
Luc@Mulan ~
$ cd bin
Luc@Mulan ~/bin
$
the title of the mintty widow remain to "~".
The same sequence with cmd window change the title to "~/bin"
The title is correctly updated only after I close emacs and push a
return to the main window.
Any explanation? Thanks
Noted first, this is in any case not a mintty issue as mintty
updates the title whenever it receives the respective escape
sequence. The scenario sounds weird, however. Is the background
process continuously sending title escape sequences? But 'emacs &'
looks like you're starting a GUI instance of emacs, right? So why
should it?
Try to isolate the background instance from the terminal:
emacs > /dev/null 2>&1 &
Even if your proposal solve the issue, I have a question of what's
append in the two different cases.
I use the same sequence (1/ cd ztry 2/ launch emacs ("emacs &" or
"emacs > /dev/null 2>&1 &" 3/ cd .. 4/ exit emacs 5/ newline 6/ ^D)
with mintty configure for logs.
The log for the first case (mintty1459.log) is strongly longer that
the second one (mintty1470.log). It look like the wall window content
is rewritten each time a line is added.
I would appreciate if someone can give me some explanation. It look
like that I have the same kind of behavior with other program (i.e.
scala repl or sbt)
It seems to be the magic of the ConPTY handling (either on cygwin side
or on Windows side) to replay the title escape sequence after the
program has been sent to the background. Your log does not yet reveal
the whole story, though:
Is it repeatedly only initially (as seen two lines below "emacs &") or
more often as might be assumed by your symptom description?
