Popup Window does not scroll about nnn.vim HOT 15 CLOSED

Work around for now is to change the &shell to something like zsh

I am on zsh and still see the same issue. Tried let g:nnn#shell = '/usr/bin/zsh' too.

from nnn.vim.

I am also experiencing this bug:
OS: macOS 10.15.5
Terminal: iTerm2
Shell: zsh 5.7.1
Vim version: 8.2.1100
Plugin manager: vim-plug
Plugin version: master
Nnn version: 3.2

from nnn.vim.

I was unable to reproduce this issue with the given nnn.vim configuration.
OS: Ubuntu 20.04
Terminal: gnome-terminal
Shell: tried with both bash and zsh
Vim version: Neovim 0.4.3
Plugin manager: vim-plug
Plugin version: master
Nnn version: 3.0

from nnn.vim.

I am also experiencing this bug

OS: Arch
Terminal: Termite
Shell: bash 5.0.18
Vim version: 8.2.1704
Plugin manager: vim-plug
Plugin version: master
Nnn version: 3.4

from nnn.vim.

@mcchrish can you take a look? Otherwise, someone has to pitch in.

from nnn.vim.

I'm not able to reproduce the bug. Using vim or neovim, nnn version 3.4.
I opened an nnn popup window to view a directory with lots of subdirs and files, still able to scroll through them.

Does it only happen with popup/floating windows?

from nnn.vim.

@mcchrish For me, yes it only happens with popup/floating windows. Scrolling through a directory with more files/folders than there are lines in the popup window cause a bunch of weird things to happen.

Here is a recording of what it looks like to me: https://asciinema.org/a/360436

This is just me repeatedly hitting j to move down through the files on the root of my system. As you can see, when it starts scrolling, things get weird.

My vimrc: https://github.com/pricheal/dotfiles/blob/master/.vimrc
and my vim config for nnn.vim: https://github.com/pricheal/dotfiles/blob/master/.vim/plugin/nnn.vim

Edit: here is scrolling working normally without floating window: https://asciinema.org/a/360438

from nnn.vim.

I'm now able reproduce the bug on vim + bash.
Bash:

GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin19)
Copyright (C) 2007 Free Software Foundation, Inc.

Vim:

VIM - Vi IMproved 8.2 (2019 Dec 12, compiled Sep 16 2020 23:47:44)
macOS version
Included patches: 1-1700

Minimal vimrc:

set nocompatible
set hidden

let g:nnn#command = 'nnn -C'
let g:nnn#layout = { 'window': { 'width': 0.9, 'height': 0.6, 'highlight': 'Debug' } }
set shell=/bin/bash

call plug#begin('~/.local/share/nvim/vendor')
Plug '~/vimming/nnn.vim'
call plug#end()

I'm not sure if there is anything else this plugin can do to fix the bug. It could be a problem coming from either Vim terminal, bash or nnn itself. (Also able to reproduce bug in floatterm nnn wrapper).

Work around for now is to change the &shell to something like zsh or move to neovim.
I made an option to configure the shell which this plugin will use with the setting g:nnn#shell. e.g let g:nnn#shell = '/bin/zsh'. See :h g:nnn#shell. 02c625f

I honestly havent experienced this issue since moved to a new laptop and reinstalled linux. So i cant help troubleshoot further.

from nnn.vim.

For me it works if airline is not loaded.

from nnn.vim.

@mcchrish I am still experiencing this issue and haven't been able to figure out any fix. What specifically would I need to put in my vim config for the work around you listed above (with the &shell option)?

from nnn.vim.

Maybe the issue is related to 256-colors when setting NNN_COLORS in 256 color format see

export NNN_COLORS='#0a0a0a0a'

it also works for me (even with airline)

from nnn.vim.

Setting my shell to zsh doesn't fix the issue for me, neither does changing any color settings with the -C option or the NNN_COLORS environment variable.

from nnn.vim.

Similar issue: voldikss/vim-floaterm#171

from nnn.vim.

The original issue submitter mentioned he is not seeing this anymore. I am also not seeing any glitches after moving to nvim.

For others who see this on vim - it's probably broken in vim. If you are on vim, consider moving to neovim.

We will not waste our time on vim-only issues going forward. Being a legacy software, it has a huge community for namesake, but not a single member buzzes when it comes to actual contribution.
