Navigating between nvim splits doesn't work with nvim.appimage

[niklaas]

When using nvim.appimage from official releases (https://github.com/neovim/neovim/releases) navigating within nvim between splits doesn't work. I assume this has something to do with

is_vim="ps -o state= -o comm= -t '#{pane_tty}' \
    | grep -iqE '^[^TXZ ]+ +(\\S+\\/)?g?(view|n?vim?x?)(diff)?$'"
bind-key -n C-h if-shell "$is_vim" "send-keys C-h"  "select-pane -L"
bind-key -n C-j if-shell "$is_vim" "send-keys C-j"  "select-pane -D"
bind-key -n C-k if-shell "$is_vim" "send-keys C-k"  "select-pane -U"
bind-key -n C-l if-shell "$is_vim" "send-keys C-l"  "select-pane -R"
bind-key -n C-\ if-shell "$is_vim" "send-keys C-\\" "select-pane -l"

which catches the input (e.g. <c-j>) because grep -iqE ... doesn't match on nvim.appimage.

I already tried renaming nvim.appimage to nvim and copying it into /usr/bin but that didn't solve the issue. I don't want to fiddle around with above regex though because it seems quite sophisticated. :-)

When removing above lines from my .tmux.conf I can navigate between splits in nvim.appimage again. That said, obviously I then can no longer use navigation between nvim and tmux splits.

201 should solve this.

Can you share the output of running : TmuxNavigatorProcessList in Vim as described here?

[niklaas]

@christoomey sorry, I forgot about that.

:TmuxNavigatorProcessList run in nvim.appimage:

> bin/nvim.appimage --version | head -1
NVIM v0.3.2-152-g1593ee7cf

S zsh
S AppRun

:TmuxNavigatorProcessList run in nvim (distro install):

> nvim --version | head -1
NVIM 0.1.7

S zsh
S nvim
S tmux: client

:TmuxNavigatorProcessList run in vim:

> vim --version | head -1
VIM - Vi IMproved 8.0 (2016 Sep 12, compiled Sep 30 2017 18:21:38)

S zsh
S vim
S tmux: client

Ha! So, I guess AppRun isn't caugth by the regex.

@blueyed I'll go through #201 later.

I'll keep you both updated.

[niklaas]

To be honest, I am not quite sure what to make of #201. As far as I understand the discussion, the proposed fix requires a newer tmux version -- mine is 2.3 though.

Probably I should keep things simple and just use the nvim version distributed by the package manager.

[niklaas]

I just figured out that building nvim from source works.

[blueyed]

Yes, it is certainly the regex/process name here. Maybe the appimage could set this somehow? (so it does not show up as "AppRun")

As for #201 the tmux.conf from https://github.com/christoomey/vim-tmux-navigator/pull/201#issuecomment-400220865 works with older tmux versions.

[blueyed]

You might want to ask in Neovim's issues about having better output with ps for the appimage. (I have not used them myself, so have no experience)

This is also a problem for me. My sysadmin installed neovim and made it available to me only as an appimage.
