Bash

.bash_profile

[[ -f ~/.profile ]] && . ~/.profile

[[ -f ~/.bashrc ]] && . ~/.bashrc

.bashrc

My .bashrc, which has pieces from the default ones in Guix & Manjaro, as well some mine settings.

Startup & environment

Export 'SHELL' to child processes. Programs such as 'screen' honor it and otherwise use /bin/sh.

export SHELL

We are being invoked from a non-interactive shell. If this is an SSH session (as in "ssh host command"), source /etc/profile so we get PATH and other essential variables.

if [[ $- != *i* ]]
then
    [[ -n "$SSH_CLIENT" ]] && source /etc/profile
    return
fi

Source the system-wide file

source /etc/bashrc

Guix dependency
xhost

Allow other users to access X server. Necessary for stuff like aw-watcher-window.

xhost +local:root > /dev/null 2>&1

Set manpager to bat

export MANPAGER="sh -c 'sed -e s/.\\\\x08//g | bat -l man -p'"

Launch fish

Launch fish shell unless bash itself is launched from fish.

use_fish=true

if [[ $(ps --no-header --pid=$PPID --format=cmd) != "fish" && ${use_fish} && $(command -v fish) ]]
then
    exec fish
fi

The rest of .bashrc is not executed if fish was launched.

Colors

Setting for colors, packed in the default .bashrc in Manjaro

use_color=true

# Set colorful PS1 only on colorful terminals.
# dircolors --print-database uses its own built-in database
# instead of using /etc/DIR_COLORS.  Try to use the external file
# first to take advantage of user additions.  Use internal bash
# globbing instead of external grep binary.

Fish

Guix dependency	Description
fish	An alternative non POSIX-compliant shell

Fish shell is a non-POSIX-compliant shell, which offers some fancy UI & UX features.

Launch starship

starship init fish | source

Enable vi keybindings & aliases. The alias syntax is the same as in bash, so it's just a noweb reference to .bashrc.

fish_vi_key_bindings

Anaconda

function init_conda
    eval /home/pavel/.guix-extra-profiles/dev/dev/bin/conda "shell.fish" "hook" $argv | source
end

Guix dependency
dt-colorscripts

Launch a random DT's colorscript unless ran inside tmux or Emacs.

if ! test -n "$TMUX"; and ! test -n "$IS_EMACS";
    colorscript random
end

Suppress fish greeting

set fish_greeting

Tmux

Guix dependency
tmux
python-tmuxp

tmux is my terminal multiplexer of choice.

It provides pretty sane defaults, so the config is not too large. I rebind the prefix to C-a though.

Term settings

I have no idea how and why these two work.

set -g default-terminal "screen-256color"
set -ga terminal-overrides ",*256col*:Tc"

History limit.

set -g history-limit 20000

Keybindings

Enable vi keys and mouse.

set-window-option -g mode-keys vi
set-option -g xterm-keys on
set-option -g mouse on
set -sg escape-time 10

Change prefix from C-b to C-a.

unbind C-b
set -g prefix C-a
bind C-a send-prefix

Vi-like keybindings to manage panes & windows.

bind h select-pane -L
bind j select-pane -D
bind k select-pane -U
bind l select-pane -R

bind s split-window
bind v split-window -h

bind-key n new-window
bind-key t next-window
bind-key T previous-window

Reload the config.

bind r source-file ~/.tmux.conf

Copy to clipboard

Guix dependency
xclip

Make tmux copying copy to clipboard as well

bind-key -T copy-mode-vi MouseDragEnd1Pane send-keys -X copy-pipe-and-cancel "xclip -selection clipboard -i"
bind-key -T copy-mode-vi y send-keys -X copy-pipe-and-cancel "xclip -selection clipboard -i"

Alacritty

Guix dependency
alacritty

Alacritty is a GPU-accelerated terminal emulator. I haven't found it to be an inch faster than st, but configuration the in yml format is way more convinient than patches.

Once again, we have an application which doesn't support reading Xresources, so here goes noweb.
