Works in iTerm2 and xterm. - patch_terminfo_bugs(): Add title-stacking sequences (\e[22t and \e[23t) to the overrides for iTerm2 and xterm. - Note: the builtins (terminfo_defs.h) for `iterm_256colour_terminfo` and `xterm_256colour_terminfo` already include the sequences. Test case (title should be "foo" after the final :q): TERM=iterm2 nvim -u NONE +'set title titleold=foo' :q TERM=iterm2 nvim -u NONE +'set title titlestring=zub' :q closes neovim#4063

There was a problem hiding this comment.
@justinmk description mentions xterm but this code is for rxvt, which one is correct?
|
@bfredl that change was for rxvt, though I admit I don't know if rxvt actually supports title-stacking. Hoping someone will test if they have a Linux desktop :) (at least to check that there is no regression, e.g. spurious sequences printed to the display) |
|
@justinmk So it was intentional that this was not implemented for xterm, even if the commit message says it "works in iTerm2 and xterm"? |
|
@bfredl I assume xterm terminfo will have up-to-date entries. But actually, I would like to experiment (after 0.3.2 release) with always sending these "title stacking" codes unconditionally, for all terminals. |
|
@justinmk so the "Add title-stacking sequences to the overrides for iTerm2 and xterm" was meant to be "iTerm2 and rxvt" in the commit message? |
|
@bfredl No, but I admit it's confusing. Sending a followup shortly. |

Rework neovim#9407: save/restore title/icon always (for all terminals). Works in tmux, iTerm2, xterm, and any other terminal that supports title-stacking. Test case (title is "foo" while running, then restored after exit): tmux nvim -u NONE +'set title titlestring=foo' :q closes neovim#4063

Forcing TERM=iterm2 is necessary because terminfo on my system is outdated:
