# Simple Scripts
2020-11-23 09:35:26 +00:00
## Audio
**audio/mute.sh**
Just a simple script to toggle Alsa mute.
**audio/noise-cancel.sh**
Add a noise-cancelled version of existing interfaces to Pulseaudio.
**audio/stream-podcasts.pl**
Commandline podcast streamer. Fetchs the feed for desired podcasts, find items
published today, then plays them in order. Given arguments, it will use those
as feeds, otherwise it will use the hash listed in the script.
## i3
2020-11-23 09:35:26 +00:00
I haven't used i3 in earnest for quite some time since moving to Sway, so it is
very likely that some of these scripts are broken based on other config changes.
**i3/i3move.sh**
2020-11-23 09:35:26 +00:00
When any of the Xrandr scripts below is run, it will print it's name to a config
file. This script will read that config file and then knows how the outputs are
arranged. Once this is known, it allows hotkeys to know which output to move a
workspace to.
**i3/detached.sh**
Xrandr config. Just the laptop display.
2020-11-23 09:35:26 +00:00
**i3/detached.sh**
2020-11-23 09:35:26 +00:00
Xrandr config. Just the laptop display.
**i3/home.sh**
2020-11-23 09:35:26 +00:00
Xrandr config. Not a layout I currently use. Home is now the "stacked" view from
sway/displays.
**i3/work.sh**
Xrandr config. Vertical on the left, horizontal aligned to top of the vertical,
and laptop directly below that. Left-to-right order is
Vertical-Horizontal-Laptop.
## Rofi
2020-11-23 09:35:26 +00:00
[Rofi](https://github.com/davatorium/rofi) is a neat graphical launcher and menu
system. I use it for a bunch of stuff to supplement i3 and Sway to fill out same
desktop niceties. See configs in 'dotfiles' repository.
**rofi/drun.sh**
Simple launcher.
**rofi/rofi-openvpn.sh**
Quick VPN switcher.
**rofi/rofi-power-menu.sh**
Lock, log out, restart Sway/i3, restart waybar, hibernate, reboot, shutdown.
**rofi/rofi-send-to-kodi.sh**
Forward pasted link to ./send-to-kodi.sh.
**rofi/rofi-ssh-menu.sh**
2020-11-23 09:35:26 +00:00
Open a terminal to any SSH shortcut machine. (TODO: Integrate with 'sshs' to get
machine list from there instead of a static list).
**rofi/sway-alt-tab.sh**
Show all currently running applications in Sway to locate window.
## Sway
2020-11-23 09:35:26 +00:00
[Sway](https://github.com/swaywm/sway) is an i3-compatible Wayland compositor
and tiling window manager. See configs in 'dotfiles' repository. Here are some
scripts exclusively for automating or enhancing Sway.
**sway/displays.pl**
2020-11-23 09:35:26 +00:00
Script to automatically configure wayland outputs using swaymsg. Also forks
waybars for each display. Allows custom configurations. No argument will run the
last used configuration (~/config/last_display). '-w' will run only waybar
without changing displays.
**sway/gammastep.pl**
2020-11-23 09:35:26 +00:00
Setup Gammastep based on current location. I don't have geolocation in my
laptop, so this requires a URL that returns JSON, including a "lat" and "lon".
My URL (restricted to my IPs) returns these as recorded by PhoneTrack on my
phone similar to:
```
{"lat":"180.12345678","lon":"-180.12345678","timestamp":"1599831660"}
```
2020-11-23 09:35:26 +00:00
It forks to keep running if terminal is killed. If location fails to be fetched
it will try again every 5 seconds.
**sway/popup-term.pl**
2020-11-23 09:35:26 +00:00
A DIY version of the Tilde terminal. If terminal is not running, it opens on the
current display. If it is running but not on current dislpay, it moves to
current display. If it is already on current display, it is moved to a hidden
display ('grave').
2020-11-23 09:35:26 +00:00
Note the relevant settings in dotfiles repository (sway/config) related to the
'grave' workspace, as well as UXTerm.
```
for_window [class="UXTerm"] floating enable, resize set height 600px, resize set width 800px, move position 1120px 460px
# Grave '`' key, DIY version of Tilde pop-up terminal
bindsym $mod+Grave exec /home/jpm/scripts/sway/popup-term.pl
# Visit the hidden grave workspace
bindsym $mod+Shift+Grave workspace grave
```
2020-11-23 09:35:26 +00:00
Also note that 'grave' has no label in waybar (waybar/config.template) to allow
it to be *hidden*.
```
"sway/workspaces": {
2020-11-23 09:35:26 +00:00
"format": "{icon}",
"format-icons": {
2020-11-23 09:35:26 +00:00
"0": "0 \uf073", // Example of workspace with a label
"grave": "",
...
```
**sway/swayidle.sh**
Work in progress. These scripts don't currently work the way I like.
2020-11-23 09:35:26 +00:00
Sway has an Idle detection daemon that can flexibly take different actions after
certain periods of inactivity as well as prior to sleep and after wake.
2020-11-23 09:35:26 +00:00
This script is meant to unify all of the actions into one script by accepting an
option.
**sway/swayidlecountdown.sh**
2020-11-23 09:35:26 +00:00
Prior to locking a countdown should be provided. Currently testing how to manage
a countdown with Dunst, which doesn't actually support dynamic notifications.
## Thinkpad
**thinkpad/blc.pl**
2020-11-23 09:35:26 +00:00
Overly complicated backlight brightness control script. Provides flexible
control of backlight so that changes can be easily scripted or called from
keyboard shortcuts. --help provides some usage docs.
**thinkpad/kbd_backlight.pl**
2020-11-23 09:35:26 +00:00
Simple script to cycle keyboard backlight. Gets max brightness, current
brightness and then changes then increments the current brightness. Uses mod of
max+1 so that it will cycle back around to 0 (disabled) if it is already at max.
**thinkpad/user-thinkpad-control@.service**
2020-11-23 09:35:26 +00:00
SystemD unit file used to give ownership of necessary sys files to whichever
user it is enabled for `systemctl enable user-thinkpad-control@jpm`. Without
this, the user won't be able to write these files and thus cannot set brightness
values.
## Waybar
2020-11-23 09:35:26 +00:00
[Waybar](https://github.com/Alexays/Waybar) is a very flexible and customizable
taskbar for Sway (and other Wlroots-based wayland compositors). Waybar applets
have hover and click functionality and have several scripts related to those.
See the .config repository for the actual Waybar and Sway configs.
2020-11-23 09:35:26 +00:00
**waybar/waybar-cpu.sh**
Launch htop in floating window (bottom-right). If already running, kill it.
**waybar/waybar-disk.sh**
2020-11-23 09:35:26 +00:00
Notification with disk usage summaries. Renders properly with Dunst, but not
Mako.
**waybar/waybar-mem.sh**
Notification with memory usage summaries.
**waybar/waybar-nmtui.sh**
Launch nmtui in floating window (bottom-right). If already running, kill it.
## Miscellaneous
**apply-gruvbox.sh**
A single theme version of the one provided
[here](https://raw.githubusercontent.com/Mayccoll/Gogh). Applies the theme to a
variety of terminals. Not really necessary after cloning the 'dotfiles'
repository.
**send-to-kodi.sh**
2020-11-23 09:35:26 +00:00
[This script](https://github.com/allejok96/send-to-kodi) sends a URL or local
file to a [Kodi](https://github.com/xbmc) media player. Only modified to have my
local media server IP.
**setup_wireguard.sh**
Script to install WireGuard and generate a config file. Requires modification
with the server public IP, server public key, and change to first 3 octets if
necessary. Will attempt to resolve dependencies and has a special case for
Raspberry Pi (detected with `uname -m` as 'arm'.
