tmux vim select pane

January 4, 2022 - Reading time: 2 minutes

This is a tweak of https://github.com/mislav/dotfiles/blob/master/bin/tmux-vim-select-pane which is linked from https://github.com/christoomey/vim-tmux-navigator as a possible fix for the vim integration.

I couldn't get the original one to work right on tmux 1.8 so I fixed it up.

These go into tmux config file:

bind-key -n C-h run-shell "~/tmux-vim-select-pane -L"
bind-key -n C-j run-shell "~/tmux-vim-select-pane -D"
bind-key -n C-k run-shell "~/tmux-vim-select-pane -U"
bind-key -n C-l run-shell "~/tmux-vim-select-pane -R"
bind-key -n C-\ run-shell "~/tmux-vim-select-pane -l"
bind C-l send-keys 'C-l'

The new script is:

#!/bin/bash
# Like `tmux select-pane`, but sends a `<c-h j="" k="" l="">` keystroke if Vim is
# running in the current pane, or only one pane exists.
#set -e
cmd="$(tmux list-panes -F '#{pane_active} #{pane_tty}' | grep '^1')"
X=$(ps -o comm= -t $(echo $cmd | cut -f2 -d' ') | grep vim)
isvim=$?
pane_count="$(printf %d $(tmux list-panes | wc -l))"
if [[ ($isvim = 0) || ($pane_count = 1) ]]; then
#if [ $isvim -eq 0 ]; then
  direction="$(echo "${1#-}" | tr 'lLDUR' '\\hjkl')"
  # forward the keystroke to Vim
  tmux send-keys "C-$direction"
else
  tmux select-pane "$@"
fi

Add Some Color to Man Pages

June 14, 2021 - Reading time: ~1 minute

I was looking through my .bashrc and came across this. I've been using it so long that I had forgotten that colorized Man pages aren't usually the default. I can't remember where I found it.

Add some color to your man pages.

    man() {
    LESS_TERMCAP_md=$'\e[01;31m' \
    LESS_TERMCAP_me=$'\e[0m' \
    LESS_TERMCAP_us=$'\e[01;32m' \
    LESS_TERMCAP_ue=$'\e[0m' \
    LESS_TERMCAP_so=$'\e[45;93m' \
    LESS_TERMCAP_se=$'\e[0m' \
    command man "$@"
    }
