描述

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

研究方向
Examine Mosh's terminal emulator implementation in the src/terminal directory. Focus on how escape sequences are currently parsed (likely in a file like terminal/terminalemulator.cc). Add parsing for CSI Ps SP q to change cursor style and OSC sequences (Ps;Pt ST/BEL) to change cursor color. Ensure the cursor state is stored and communicated to the frontend. Look at existing handling of other OSC sequences for guidance. Test by running vim with appropriate terminal settings.
