# Bare Git Repository

- <https://www.atlassian.com/git/tutorials/dotfiles>
- StreakyCobra

## Starting from scratch

```sh
git init --bare $HOME/.dotfiles
alias dotfiles='/usr/bin/git --git-dir=$HOME/.dotfiles --work-tree=$HOME'
dotfiles config --local status.showUntrackedFiles no
```

## Install onto a new system

The `checkout` command is expected to fail with a message.
This is because your $HOME folder might already have some stock configuration
files which would be overwritten by Git.
The “BKDIR” part is a rough shortcut to move all the offending files
automatically to a backup folder:

```sh
git clone --bare <git-repo-url> $HOME/.dotfiles

alias dotfiles='/usr/bin/git --git-dir=$HOME/.dotfiles --work-tree=$HOME'

dotfiles config --local status.showUntrackedFiles no

BKDIR=".dotfiles-backup/";
dotfiles checkout 2>&1 | egrep "\s+" | awk {'print $1'} |
  xargs -I{} sh -c "mkdir -p \$(dirname ${BKDIR}{}); mv -iv {} ${BKDIR}{}";

dotfiles checkout
```

When the `fetch` configuration is not set, insert the following line in
`.dotfiles/config`:

```config
    fetch = +refs/heads/*:refs/remotes/origin/*
```

## Install into `/etc/skel`

```sh
sudo mkdir -p /etc/skel/.dotfiles
sudo chown $(whoami) /etc/skel

git clone --bare $(dotfiles remote -v | head -1 | cut -f2 | cut -f1 -d' ') /etc/skel/.dotfiles

alias skelfiles='/usr/bin/git --git-dir=/etc/skel/.dotfiles --work-tree=/etc/skel'
skelfiles config --local status.showUntrackedFiles no
skelfiles checkout
```

## Useful Commands

- List all tracked files (from CWD):  
  `dotfiles ls-tree --name-only -rz main | xargs -0 $(whence lsd) -lU`

## Other Tools

```sh
lazygit --git-dir=$HOME/.dotfiles --work-tree=$HOME
```

# Install remotes as subtree

- <https://www.atlassian.com/git/tutorials/git-subtree>
- Create an alias for remote repository
  - `dotfiles remote add <remote-name> <URL>`
- Import remote as a single commit (squashed)
  - `dotfiles subtree add --prefix <target-folder> <remote-name> <branch> --squash
  - Note 1: Must be called from $HOME
  - Note 2: Do not start <target-folder> with $HOME or ~

## Generic Tips

### Desktop Files

See <https://specifications.freedesktop.org/desktop-entry-spec/latest/>

### Github Patches

From [stackoverflow](https://stackoverflow.com/questions/28484186/apply-github-commit-pull-request-as-a-patch).

```sh
wget https://github.com/jesseduffield/lazygit/pull/2604.patch
git apply --stat --apply 2604.patch
```

### Qubes Internet Access

- In _Basic_, connect to `sys-firewall`;
- In _Firewall rules_:
  - check _Limit outgoing connections_;
  - check _Allow full access for 25 minutes_.

## System Config

- [SysRq](https://www.kicksecure.com/wiki/SysRq)

## Debian Packages {#debian}

```sh
apt install curl fd-find fzf git grc ripgrep wget xdg-utils

dpkg-divert --divert /usr/bin/fd --rename /usr/bin/fdfind
dpkg-divert --divert /usr/share/man/man1/fd.1.gz --rename /usr/share/man/man1/fdfind.1.gz
dpkg-divert --divert /usr/share/zsh/vendor-completions/_rg --rename /usr/share/zsh/vendor-completions/rg.zsh
```

## ASDF & main plugins {#asdf}

`.zshrc` will install `asdf`.

Make sure you have the required [system dependencies](https://github.com/pyenv/pyenv/wiki#suggested-build-environment)
before installing/compiling Python.

```sh
sudo apt install --no-install-recommends XXX

asdf plugin add direnv
asdf plugin add python
cd ~/bin
asdf current
asdf install
```

## Fonts {#fonts}

- [JetBrains Mono](https://www.jetbrains.com/lp/mono/)
  - Install the files **without** “NL” (No Ligatures) in their names

- [Nerd Fonts](https://www.nerdfonts.com/)
  - [Download](https://github.com/ryanoasis/nerd-fonts/tags)
    - JetBrainsMono.tar.xz
    - NerdFontsSymbolsOnly.tar.xz
  - [Cheat Sheet](https://www.nerdfonts.com/cheat-sheet)
  - <https://raw.githubusercontent.com/ryanoasis/nerd-fonts/master/bin/scripts/test-fonts.sh>

### in /opt/fonts

`/etc/fonts/conf.d/00-opt.conf`:

```xml
<?xml version="1.0"?><!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<dir>/opt/fonts</dir>
</fontconfig>
```

### in $HOME/.fonts

```sh
mv folder ~/.fonts
fc-cache -fv ~/.fonts
```

See also [How to install and manage fonts on Linux](https://linuxconfig.org/how-to-install-and-manage-fonts-on-linux).

### in /opt/fonts

`/etc/fonts/conf.d/00-opt.conf`:

```xml
<?xml version="1.0"?><!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<dir>/opt/fonts</dir>
</fontconfig>
```

```sh
sudo mv folder /opt/fonts
fc-cache -fv /opt/fonts
```

## kitty {#kitty}

- <https://sw.kovidgoyal.net/kitty/binary/>

### Dependencies

- `JetBrains Mono` (without NL)
- `NerdFontsSymbolsOnly`
  - Note: outside of kitty, it may be interesting to also install
    _JetBrains Mono_ **with** _NL_.
- terminfo

```sh
sudo apt install kitty-terminfo
 # OR:
wget 'https://salsa.debian.org/debian/kitty/-/raw/debian/sid/terminfo/x/xterm-kitty
```

### Install

```sh
 # Show installed version, debian package & changelog
(ls =kitty;
 kitty --version;
 apt show kitty;
 curl https://sw.kovidgoyal.net/kitty/changelog/ | html2text) | less

 # Debian package
sudo apt install kitty

 # In $HOME
sh ~/.config/kitty/installer.sh

 # In /opt/kitty.app
sudo sh ~/.config/kitty/installer.sh launch=n dest=/opt
sudo update-alternatives \
  --install /usr/bin/x-terminal-emulator \
  x-terminal-emulator /opt/kitty.app/bin/kitty 99
```

**Note**:
Kitty prepends its _bin_ folder to the path.
So it is more coherent/simpler to copy this behaviour into Zsh.

## lazygit {#lazygit}
