I am using Konsole + ZSH in KDE with several tabs open. In some tabs I run different programs -- Python scripts with ipdb and other. At some point I cannot enter new line anymore -- pressing Enter
just prints ^M
.
I saw this answer and I think ipdb changes some of terminal settings which are not restored when I interrupt it pressing Ctrl+C
or Ctrl+\
:
$ stty -a
speed 38400 baud; rows 46; columns 180; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>;
swtch = <undef>; start = ^Q; stop = ^S; susp = <undef>; rprnt = ^R; werase = ^W;
lnext = <undef>; flush = ^O; min = 1; time = 0;
-parenb -parodd -cmspar cs8 -hupcl -cstopb cread -clocal -crtscts
-ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr -icrnl -ixon -ixoff

isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt echoctl echoke
$ pip uninstall frozendict
Uninstalling frozendict:
...
Proceed (y/n)? ^M
Another terminal which works ok has these settings:
$ stty -a
speed 38400 baud; rows 46; columns 180; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>;
swtch = <undef>; start = ^Q; stop = ^S; susp = <undef>; rprnt = ^R; werase = ^W;
lnext = ^V; flush = ^O; min = 1; time = 0;
-parenb -parodd -cmspar cs8 -hupcl -cstopb cread -clocal -crtscts
-ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl -ixon -ixoff
-iuclc -ixany -imaxbel iutf8
opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0
isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt echoctl echoke
So am thinking how to work around this.
I could somehow inject stty icrnl
to be executed after a command was executed, but I would rather restore all settings not just icrnl
. But reset
is slow.
So my question is: how to execute something after a command was executed in ZSH and what to execute -- stty icrnl
or reset
? Or is there another solution?
Or is there a way to prohibit disabling icrnl
flag?
