Nano only does this when the terminfo says the cbt capability is supported.
Mac os xterm to remote terminal mac os x#
The version of nano shipped with Mac OS X Lion 10.7 doesn't do this. I don't know why it does this around tab stops instead of always moving left/right using the same character sequences. Similarly, IIRC, it sends a Tab (Control-I) when moving to the right and the cursor is one character to the left of a tab stop.
The version(s?) of nano on those servers sometimes sends a Backtab (ESC [ Z) sequence when moving the cursor left by one character, but Terminal doesn't support this sequence, so nano thinks the cursor has moved when it hasn't and its idea about the current position of the cursor is out of synch with the terminal.įor reasons I can't fathom, nano sends a Backtab when moving to the left and the cursor is one character to the right of a tab stop. I found Linode Lish Shell Vim and Nano rendering troubles: lines not appearing / cursor positions wrong, but I don't know if that relates much, since that's specifically referring to lish. It's a big problem when it comes to editing configuration files, because I often have to edit one line, save and close, then reopen just to make sure that line is right. I end up getting things like "This is a neof text." When I had typed in (to the cursor-crazy editor) "This is a line of text." Once I start editing the file, if I use the arrow keys to move around the cursor, or start deleting, then typing again, the cursor jumps around a bit, and if I save the file and reopen it, it's obvious that the cursor was, in fact, jumping all over the place on a line for no apparent reason.
Basically (this has been happening over the past couple months), I log into a few different CentOS servers (one Linode, another VPS, and a shared host to which I have shell access), running 5.5, 5.7, and 6, from my Mac running OS X Lion, using Terminal.
