what is this post about
Depending on the day, or the season, I either find myself an ally to the idea that every single thing on my system needs to be custom configured, or I use the default configuration of a tool for seven years in a row not once changing a single thing.
Today I’m looking at my
.tmux.conf which is an artifact of somewhere in between of those states. I want to share a few things that made me happy and productive with it. The file is 28 lines long, but a third of it are comments. Conservative.
unbind C-b set-option -g prefix C-f bing-key C-f send-prefix
First of all, C-b feels to my hands like a violation of the home row, and thus I move
f. I never could press it without moving my hand.
bind r source-file ~/tmux.conf \; display "~/.tmux.conf sourced"
If you play with the config a lot, you want the above. Reloads the config for ya.
set -g base-index 1 set -g pane-base-index 1
Zero indexing is fine in programming languages. When I am switching windows and panes it feels sacrimonious to be pressing
0 for first window, but
1 for the second.
bind k split-window -v bind K split-window -h unbind % unbind \"
vim keybindings. My fingers are always on
k. And so I use
Kfor window splits.
set -g default-terminal "screen-256color" set -g status-bg black set -g status-fg white
The green was jarring. Black and white suits me.
set-window-option -g mode-keys vi bind-key -T copy-mode-vi 'v' send -X begin-selection bind-key -T copy-mode-vi 'y' send -X copy-selection-and-cancel
No config of a tool is complete without some
vi remaps, including a few copying tricks. I found that between various emulators (
iterm, default macos
vsc terminal) those settings fall apart, and I haven’t been annoyed enough yet to fix this.
Moving around panes
You may notice lack of mappings for moving between panes / splits. I use arrow keys, apart from the fact that I don’t - it’s more intricate and a lot of the smoothness of motion around tmux I benefit from comes from my os-wide keyboard remaps using karabiner. But that’s a topic for another post.
