Cursor Color and Style changes #352

Open Shoozza opened 11 years ago

Shoozza commented 11 years ago

MinTTY allows to change cursor styles and colors but mosh ignores them. This would be useful for vim (different insert and normal mode cursors)

Mode-dependent cursor in vim: CSI Ps SP q

Example: echo -ne '\e]12;#00FF00\a' # green cursor http://code.google.com/p/mintty/wiki/Tips#Mode-dependent_cursor_in_vim

Changing colors: OSC Ps ; Pt ST OSC Ps ; Pt BEL

Example: echo -ne "\e[2 q" # non blinking block cursor http://code.google.com/p/mintty/wiki/Tips#Changing_colours

Not just mintty. This is across the board. Mosh currently only looks for visibility and position of the cursor.

The spec is at http://vt100.net/docs/vt510-rm/DECSCUSR

There's also another sequence used by iTerm2 and Konsole https://code.google.com/p/iterm2/issues/detail?id=710 among others documented at http://vim.wikia.com/wiki/Change_cursor_shape_in_different_modes

In addition with tmux running, the codes must be further escaped by "\ePtmux;\e" and "\e\"

To make matters worse, when using tmux if you have a remote tmux session within a local tmux session, you have to send multiple codes so that it will update on multiple ends. In my case I use Konsole on linux and iTerm2 on OSX and still have to send the xterm-based sequence to get tmux within tmux to display the correct cursor even though both ends should support the same sequence.

ssh works fine because it sends the full stream both ways, but with mosh's diff based system I'm not sure how feasible monitoring all this would be because I don't think it's something that can be queried, at least not across the board, and even if it can be queried, which code should it use and on which end.

Why cursor shape definition isn't a followed standard is beyond me. Makes portability extremely difficult.

is it any work in this direction? :D

Re: Tmux: Adding set -ga terminal-overrides ',*:Ss=\E[%p1%d q:Se=\E[2 q' to .tmux.conf is the way to allow tmux to pass cursor codes. Mosh still needs to support it, ofc.

Cursor change should be possible, unlike a lot of the other open feature requests it won't add a lot of data overhead. Seems like the problem is there have been no new releases in years?
