How to restore bash terminal title if using 'set title' in vim?

Question

I recently got to know that useful info can be shown in title of bash terminal when editing files using vim. Adding below displays file name, path of the file being edited.

set title

But on exiting vim, the title is set to 'Thanks for flying vim'. I have different title set for each bash terminal and would like it to be restored once I close the vim?

Any way to change this behaviour of vim?

Answer 1

Use the titleold setting:

" Update term title but restore old title after leaving Vim
set title
set titleold=

From :help 'titleold':

This option will be used for the window title when exiting Vim if the original title cannot be restored. Only happens if 'title' is on or 'titlestring' is not empty.

Answer 2

The actual problem is that Vim does not know how to read the old title, because termcap/info is missing the control sequence to do that. But we can supply it ourselves for terminal types we know it for. Xterm and screen use the same sequence, so this will fix both:

if has ("title")

    " if there is no &t_ts sequence, is the terminal type known?
    if &t_ts == "" && ( &term == "screen" || &term == "xterm" )
        " add the missing control sequence for xterm or screen 
        let &t_ts = "\e]2;"
    endif

    " enable setting the title only if vim can read the old one
    if &t_ts != ""
        set title
    endif

endif

Answer 3

To supress vim changing the window title just disable the function:

"disable title modification
set notitle

Answer 4

To set your bash terminal title to your short hostname when exiting vim, add this to your .vimrc:

execute "set titleold=".hostname()

At least on Arch, bash's default is the short hostname, so unless you have something else changing it sometimes, this will emulate restoring it.

Answer 5

As of 8.1.0253, Vim will use the terminal's title stack to push/pop the title. This is more robust than trying to query the title from X, but not all terminals may support this functionality.
