Tabby

export PS1="$PS1\[\e]1337;CurrentDir="'$(pwd)\a\]'

Vim
The colorscheme habamax requires additional a new version of Vim. Install on Ubuntu

sudo add-apt-repository ppa:jonathonf/vim
sudo update
sudo apt install vim -y
  • change tab to width of 2, autoindent, mouse mode etc
  • saved in ~/.vimrc
  • the file will be compatible with both Linux and Windows

In Windows Terminal specifically, Ctrl-V must be unbound
keybindings

{"id": "unbound", "keys": "ctrl+v"},

Additional configuration needed in powershell for Windows paste to work

set pastetoggle=<F2>

For transparent effect, but cursor cannot be transparent

autocmd vimenter * hi Normal guibg=NONE ctermbg=NONE
  • but it’s not possible to make the cursor transparent

Windows powershell specific keybinding

nnoremap <M-Up> :m .-2<CR>==
xnoremap <M-Up> :m '<-2<CR>gv=gv
nnoremap <M-Down> :m .+1<CR>==
xnoremap <M-Down> :m '>+1<CR>gv=gv

Undofile

set undofile
set undodir=~/.vim/undo//

Copy from remote clipboard

" Copy via osc52
source ~/.vim/bundle/vim-osc52/plugin/osc52.vim
vmap <C-c> y:call SendViaOSC52(getreg('"'))<cr>
  • need to clone from repo plugin
git clone https://github.com/fcpg/vim-osc52 ~/.vim/bundle/vim-osc52

On windows natively

set clipboard=unnamedplus
  • select a line, click "+y

On WSL

if system('uname -r') =~ "Microsoft"
  augroup Yank
    autocmd!
    autocmd TextYankPost * :call system('/mnt/c/windows/system32/clip.exe ',@")
  augroup END
endif
  • use y is enough

ZSH
Install using package manager
Plugin manager

  • zinit

Prompt

  • oh my posh

Configuration
both .bashrc and .zshrc points to .bash_aliases which consists of common config and variable that works for both

.zshrc

  • alias . to source

bash_aliases

  • PUID/PGID
  • ll, grep and other color command
  • docker related commands
  • c.. command

Consists of color consistency based on hostname

  • set _OMP_COLOR and TMUX_SESSION_FG

OMP
Install

sudo apt install unzip -y
curl -s https://ohmyposh.dev/install.sh | bash -s
mkdir -p ~/.config/ohmyposh

Place this

eval "$(oh-my-posh init zsh --config ~/.config/ohmyposh/omp.toml)"

Export configuration

oh-my-posh config export --format yaml --output ~/.config/ohmyposh/omp.yaml

Configuration require manually specifying the file

  • the folder must exist before the export

Zoxide

curl -sSfL https://raw.githubusercontent.com/ajeetdsouza/zoxide/main/install.sh | sh
eval "$(zoxide init bash)"
  • DO NOT alias z to zoxide, as z it’s a function

Everything must be edited manually
Rebind cd to z and bind z to it as well

eval "$(zoxide init --cmd cd bash)"
alias z="cd"

Netdevice

sudo iftop -i $(ip --color=never -o r get 8.8.8.8 | awk '{print $5}')

Tmux
By default, Tmux v3.5 will have error when used with Windows terminal, as it sends random data when it tries to start itself, earlier versions or latest 3.6a do not have such issues.
This could fix it but it will make Vim feel slower

set -g escape-time 500
set -g focus-events off

The better alternative is to use a portable tmux build that work across Linux distros.

wget https://github.com/mjakob-gh/build-static-tmux/releases/download/v3.6a/tmux.linux-amd64.gz
gzip -d tmux.linux-amd64.gz
chmod +x tmux.linux-amd64
tmux=$(which tmux); sudo cp tmux.linux-amd64 ${tmux:-/usr/local/bin/tmux}
rm tmux.linux-amd64.gz

For compatibility of tmux and vim on server

set ttymouse=xterm2
set -g allow-passthrough on
  • allow responsive mouse movement and passthrough osc52 from vim to tmux to system

SSH auto attach tmux

if [[ -n "$SSH_CONNECTION" && -z "$TMUX" && $- == *i* && -z $NOTMUX ]]; then
   tmux attach -t main || tmux new -s main
fi

Nano

Chezmoi
not available in apt, need manual install

sh -c "$(curl -fsLS get.chezmoi.io)"
  • must restart shell

Add/re-add

chezmoi add .bashrc
chezmoi re-add .bashrc # edit locally and add again
  • recommended to run chezmoi diff
  • re-add doesn’t work with templates, that has to be done manually

Encryption

chezmoi age-keygen --output=$HOME/key.txt

Edit the .config/chezmoi/chezmoi.toml with the file and public key

encryption = "age"
[age]
    identity = "~/key.txt"
    recipient = "age193wd0hfuhtjfsunlq3c83s8m93pde442dkcn7lmj3lspeekm9g7stwutrl"
  • make sure to also add the file as .chezmoi.toml.tmpl into ~/.local/share/chezmoi

https://www.chezmoi.io/user-guide/frequently-asked-questions/encryption/#how-do-i-configure-chezmoi-to-encrypt-files-but-only-request-a-passphrase-the-first-time-chezmoi-init-is-run
After following the steps, the files can be pushed to Github
When adding the secret file again, there’s no need to use --encrypt flag, just re-add

On another computer

sh -c "$(curl -fsLS get.chezmoi.io)" -- init --apply --ssh $GITHUB_USERNAME

This would require restarting the shell and run

chezmoi init --apply --ssh vttc08
  • the init --apply will prompt for password, if entered incorrectly, the command need to be run again before chezmoi apply

On update

chezmoi update

More careful

chezmoi git pull -- --autostash --rebase && chezmoi diff

Templating and install packages
Evaluate template variables and content for debugging

chezmoi execute-tempate < shellscript.sh

Use .chezmoiignore to manage differences between Windows and Linux
