vimrc specific hang with neovim+dash+man

[lucc]

I have mentioned it some times before so here is the full report. (see #67, #196)

system

I am on Arch Linux using neovim and dash from the repos. I don't have vim installed. The error happens no matter if I have python{,2}-neovim installed or not.

config

mv ~/.config/nvim foo
export POSIX_SHELL=/bin/dash
export MANPAGER="$POSIX_SHELL $HOME/vcs/vimpager/vimpager -x" # the path to vimpager in the git repo
export VIMINIT='python import vim'

error

Now if I do man man I get this debug output (from the -x shell option)

and it hangs forever. If I press CTRL-C these additional lines are printed:

+ rm -f gvim.exe.stackdump
+ cd /tmp/vimpager_7073/..
+ rm -rf /tmp/vimpager_7073
+ exit 1

solutions

• Previously I just used and installed vimpager with POSIX_SHELL=/bin/bash. That works.
• Using

if exists('g:vimpager.enabled') 
  python import vim
endif

in the init file doesn't help as g:vimpager.enabled is not set at that point.

I have to same problem here. It seems to be related to zsh and neovim, using bash everything is fine. From vimpager -x file I get:

Here, it hangs forever.

^C+ quit 1
+ rm -f gvim.exe.stackdump

Any ideas?
