# Archlinux System Setup for Markov

## `aconfmgr`

To use, first install from AUR.
Then clone the repo in `~/.config/aconfmgr` and run `aconfmgr apply`.

## Firefox

- [arkenfox gui](https://arkenfox.github.io/gui/)
- [arkenfox user.js](https://github.com/arkenfox/user.js/wiki/2.1-User.js)
- See [here](https://github.com/arkenfox/user.js/wiki/4.1-Extensions#-recommended) for uBlock.

  to my custom filters.

# TODOs

- complete the script `~/.local/bin/moreka`
- verify if `~/.local/bin/moreka-open` works
- XF86 keys not working...

# pam

run `gpg -K --with-keygrip` and get the Keygrip (the one under ssb), put it in
`~/.config/pam-gnupg`

# oama
oama authorize microsoft moreka@mit.edu --device

# to clone a git forked repo and add upstream repo as well
```sh
git remote add upstream https://github.com/.../....git
git fetch upstream
git branch -r # gives all branches
git checkout main # or master (my local branch)
git pull --rebase upstream main # or master
git push origin main
```

Then, start working on a fix branch:
```sh
git checkout -b feature/my-new-thing
git push -u origin feature/my-new-thing
```

From time to time, update the main branch:
```sh
git checkout main
git fetch upstream
git rebase upstream/main
git push origin main
```
and if the feature branch has diverged
```sh
git checkout feature/my-new-thing
git rebase main
```

**Always keep main clean!**

# bash inputrc

Some useful stuff here:
```
C-x p --> edit the path
C-x " --> prepare to type a quoted word
C-x q --> quote the current or previous word
C-x r --> redraw the current line
```

# GPG

```bash
gpg --import your@id.here.pub.asc
gpg --import your@id.here.priv.asc
gpg --import your@id.here.sub_priv.asc
gpg --import-ownertrust ownertrust.txt

gpg --edit-key your@id.here
```
```cmd
gpg> trust
Your decision? 5
```

# fingerprint

1. fprintd, imagemagick installed
2. pam stuff (changed hyprlock and polkit-1):
```sh
cp /usr/share/polkit-1/rules.d/50-default.rules /etc/polkit-1/rules.d/
```

```rules
polkit.addAdminRule(function(action, subject) {
    return ["unix-group:wheel"];
});
```

3. sudo fprintd-enroll -f right-index-finger moreka
4. fprintd-verify
5. sudo fprintd-enroll -f left-index-finger moreka
4. fprintd-verify

# LESS

&pattern  -> display only matching lines
ESC-u -> toggle search highlight
^O^N -> search forward for OSC8 hyperlink
^O^P -> search backward for OSC8 hyperlink
^O^L -> jump to currently selected OSC8
^O^O -> open currently selected OSC8
v -> edit file with editor
| ???
s -> save to file

-i -> ignore case

t, T -> go to next/prev tag
m<letter> -> mark top line
'<letter> -> goto mark
'' -> goto previous pos

# iPhone

works surprisingly well! Wow!

main link: [archwiki](https://wiki.archlinux.org/title/IOS)

install `libimobiledevice`, `usbmuxd`, and `ifuse`.

## Mounting iOS

After connecting, check `systemctl status usbmuxd.service`. It should be running automatically.

```bash
# pairing
idevicepair pair # might need to enter passcode and trust the computer on iphone
idevicepair validate

# data
ifuse some_user_mountpoint

# list apps
ifuse --list-apps
ifuse --documents APPID some_other_mountpoint # wasn't that useful
```
Pictures/videos are going to be in `DCIM/`.

When done, `fusermount -u mount_point`.


## Backup

```bash
# to backup
idevicebackup2 backup --full some_folder

# to restore
idevicebackup2 restore some_folder
```

- [GUI for exploring files in a backup](https://github.com/MaxiHuHe04/iTunes-Backup-Explorer)
- [Restoring firmware](https://github.com/libimobiledevice/idevicerestore) (also in the AUR: `idevicerestore-git`)

# VIM
- Interesting. Vim has a confini filetype (can be used for Python's configparser-type configs)

- using `:oldfiles`, you can do `:e #<1` to edit the first item (replace 1 with any item number)

# CachyOS Kernel Install
```bash
sudo pacman-key --recv-keys F3B607488DB35A47 --keyserver keyserver.ubuntu.com
sudo pacman-key --lsign-key F3B607488DB35A47

sudo pacman -U \
    'https://mirror.cachyos.org/repo/x86_64/cachyos/cachyos-keyring-20240331-1-any.pkg.tar.zst' \
    'https://mirror.cachyos.org/repo/x86_64/cachyos/cachyos-mirrorlist-22-1-any.pkg.tar.zst' \
    'https://mirror.cachyos.org/repo/x86_64/cachyos/cachyos-v3-mirrorlist-22-1-any.pkg.tar.zst'
```

Then, in `pacman.conf`:
```confini
Architecture = x86_64 x86_64_v3 # replace the existing "auto"

[multilib]
Include = /etc/pacman.d/mirrorlist

[cachyos-v3]
Include = /etc/pacman.d/cachyos-v3-mirrorlist

[cachyos-core-v3]
Include = /etc/pacman.d/cachyos-v3-mirrorlist

[cachyos-extra-v3]
Include = /etc/pacman.d/cachyos-v3-mirrorlist
```
Then,
```bash
sudo pacman -Syu
sudo pacman -S linux-cachyos linux-cachyos-headers
```

Then, copy the default loader into `/boot/loader/entries/cachyos-kernel.conf` and change:
```
title   Arch Linux (with cachyos kernel)
linux   /vmlinuz-linux-cachyos
initrd  /initramfs-linux-cachyos.img
options [same as the default]
```

# I also installed UEFI shell `edk2-shell` following Archwiki's guide
[link](https://wiki.archlinux.org/title/Systemd-boot#UEFI_Shells_or_other_EFI_applications)

# Fzflua undotree

# HDMI sound

```sh
wpctl status | less
```
then see what is the default at the bottom and take note of the number of the HDMI output.
After that, use
```sh
wpctl set-default 58
```

# Mirroring

Use `hyprmon`. Don't forget to apply (`A`).

# Revert back to markdown todos

# etc-update from gentoo... check it out (related to `pacdiff` from `pacman-contrib`)

# mount

# qutebrowser
- [Greasemonkey · Issue #926 · darkreader/darkreader](https://github.com/darkreader/darkreader/issues/926#issuecomment-575893299)
- need `python-idna` and `python-tldextract` for the qute-pass userscript to work; see [here](/usr/share/qutebrowser/userscripts/qute-pass:43-52).
