139157Emit Terminal Keycodes from within ViM
- Sep 14, 2013--Hi All,I've been searching on this topic for hours but couldn't find anything relevant on the internetz._What_:In VIM, map <F6> to emit/send the following Mintty terminal keycode "\e[?7727h"._Why_:Cygwin Mintty terminal has a special mode (app escape mode) when enabled emits \eO[ (instead of regular \[) on ESC key. Using this I mapped <Esc>O[ to <ESC> which immediately exits insert mode. To enable App Escape mode for mintty, the following terminal code needs to be sent "\e[?7727h". To disable the app escape mode: "\e[?7727l".I've set my &t_ti = "\e[?7727h" and &t_te = "\e[?7727l". This works great--as soon as I start VIM, vim emits the t_ti code to enable Mintty app escape mode. As soon as I exit, t_te emits the app escape off code.However, I run into a little bit of trouble when running vim inside of tmux. If I exit Vim in a window, the app escape mode OFF is sent--then switching to another running window with ViM ALREADY running causes issues since app escape mode is off and ESC key won't generate the special \eO[ code.I was thinking of a simple manual step to just emit App Escape Mode ON keycode (using F6) whenever I find ESC not working properly._How_:..... half-way through writing this post I realized a simple fix .... If I execute any SHELL command from within VIM (e.g: :!echo "hellooo"), Vim will run the script and then regain control. What I just realized is that when Vim regains control--it'll emit whatever is in &t_ti --which includes my App Escape Mode ON.Anyway, for the sake of argument is there a Vim one liner that emits terminal keycodes from INSIDE Vim (without running an external script)?See the following links for more info:
