This file will present all the executable scripts I wrote. It is also their

Because I sometimes switch from window manager to window manager, creating a
|
||
script that handles by itself autostarting things for me is way easier than
|
||
rewriting every time the autostart part of my configuration. As you can every
|
||
instance will be launched asynchronously, and only if there is no other instance
|
||
of said command running.

As I am using a laptop, maximum performance isn’t always what I want.
|
||
Sometimes, it’s just better to have not so great but less
|
||
battery-demanding performance. It is possible to achieve this by
|
||
modifying the CPU governor with ~cpupower~. The [[https://wiki.archlinux.org/title/CPU_frequency_scaling#Scaling_governors][Arch Wiki]] has, as usual,
|
||
some really good documentation on this.
|
||
|
||
The following script asks the user through ~rofi~ which governor to
|
||
apply, and it relies on [[#Askpass-d0d7a8c0][~askpass~]] to retrieve the user’s password.
|
||
#+begin_src bash
|
||
governors=("performance" "powersave" "userspace" "ondemand" "conservative" "schedutil")
|
||
governor=$(printf "%s\n" "${governors[@]}" | rofi -dmenu)

~mu-unread~ is a very simple utility that simply returns the amount of

I take screenshots by accident).

This is a utility only useful with Wayland for now, using =grim=, =slurp=

(in order to select which area of the screen I wish to capture) and

=wl-copy= (from =wl-clipboard=). It saves the screenshot in my

=$HOME/Pictures/Screenshots= directory with a name formated as
|
||
=Screenshot_20230425_134550.png= if the screenshot was taken on the 25th
|
||
of April 2023 at 1:45:50PM. If the file already exists, the script
|
||
will suffix the name with an underscore followed by an incremental
|

number like =Screenshot_20230425_134550_1.png= or
|

=Screenshot_20230425_134550_2.png=.

If the argument =select= is passed to =screenshot=, as in =screenshot

select=, then use =slurp= to select the area to capture.

Something that I did not know for quite some time, but that is

actually crazy useful about SSH is its ability to bind locally the

simple, but I prefer a more intuitive way of writing it. Its usage is

~sshbind PORT FROMHOST TOHOST~.

|
||
One thing I like with ~nsxiv~ is you can trigger different behaviors
|
||
based on keypresses. For instance, with my current nsxiv configuration,
|
||
if I press the space key followed by a character, it can delete to the
|
||
trashcan, delete definitively, or open the current image in GIMP. All
|
||
of that is done through one script file stored in
|
||
~$HOME/.config/nsxiv/exec/key-handler~. The fact it reacts to first the
|
||
spacebar instead of /Ctrl-x/ is because I use a custom version of nsxiv I
|
||
first modified to fit the bépo layout, and then I decided to change
|
||
the prefix to fit how I use Emacs and StumpWM. You can read the
|
||
PKGBUILD and my nsxiv patch [[https://labs.phundrak.com/phundrak/dotfiles/src/branch/master/Documents/code/PKGBUILDs/sxiv][in my dotfiles repo]].
|
||
|
||
#+header: :shebang "#!/usr/bin/env fish" :tangle ~/.config/nsxiv/exec/key-handler

|

|
||
<<nsxiv-switch-statement>>
|
||
#+end_src
|
||
|
||
Here is a step by step explanation of the source code. First, we want
|
||
to store in the variable ~FILES~ all the files marked in nsxiv. This is
|
||
done with a ~while~ loop and the ~read~ command.
|
||
#+name: nsxiv-read-files
|
||
#+begin_src fish
|
||
while read file
|
||
set -g FILES "$file" $FILES
|
||
end
|
||
#+end_src
|
||
|
||
We can then read from the first member of ~argv~ which key the user
|
||
pressed. Depending on it, we can choose what to execute.
|
||
#+name: nsxiv-switch-statement
|
||
#+begin_src fish
|
||
switch "$argv[1]"
|
||
<<nsxiv-trash>>
|
||
<<nsxiv-rm>>
|
||
<<nsxiv-gimp>>
|
||
<<nsxiv-jpeg>>
|
||
<<nsxiv-rotate-clockwise>>
|
||
<<nsxiv-rotate-counter-clockwise>>
|
||
<<nsxiv-yank>>
|
||
end
|
||
#+end_src
|
||
|
||
The first option with the letter ~d~ is to move the file to the trash
|
||
can. For this, we use the ~trash~ command from ~trash-cli~.
|
||
#+name: nsxiv-trash
|
||
#+begin_src fish
|
||
case "d"
|
||
trash $FILES
|
||
#+end_src
|
||
|
||
In case we want to definitively delete a file without using the trash
|
||
can, we can use ~rm~ instead when we press the ~D~ key.
|
||
#+name: nsxiv-rm
|
||
#+begin_src fish
|
||
case "D"
|
||
rm $FILES
|
||
#+end_src
|
||
|
||
It’s not rare I want to modify an image I have open in nsxiv,
|
||
especially since screenshots are automatically open in this image
|
||
viewer aften they are taken. In that case, a simple command will do.
|
||
#+name: nsxiv-gimp
|
||
#+begin_src fish
|
||
case "g"
|
||
gimp $FILES
|
||
#+end_src
|
||
|
||
Often, I use nsxiv to convert an image to a JPEG file, because my
|
||
internet connection is not that great and JPEG screenshots are faster
|
||
to upload than PNG screenshots. So what I do is for each file
|
||
selected, I take the base name of the file (i.e. remove its
|
||
extension), and then I use the ~convert~ command from ~imagemagik~ to
|
||
convert it from its original format to a JPG format --- ~imagemagik~
|
||
detects the formats based on the extension.
|
||
#+name: nsxiv-jpeg
|
||
#+begin_src fish
|
||
case "j"
|
||
for f in $FILES
|
||
set basename (echo "$f" | sed 's/\.[^.]*$//')
|
||
convert "$f" "$basename.jpg"
|
||
end
|
||
#+end_src
|
||
|
||
I have two commands to rotate my files, and both only differ by the
|
||
angle of rotation. Once again I rely on ~convert~ in both cases. To
|
||
rotate clockwise, this is the code needed.
|
||
#+name: nsxiv-rotate-clockwise
|
||
#+begin_src fish
|
||
case "r"
|
||
for f in $FILES
|
||
convert -rotate 90 "$f" "$f"
|
||
end
|
||
#+end_src
|
||
|
||
On the other hand, to rotate counter-clockwise, we need this code:
|
||
#+name: nsxiv-rotate-counter-clockwise
|
||
#+begin_src fish
|
||
case "R"
|
||
for f in $FILES
|
||
convert -rotate 270 "$f" "$f"
|
||
end
|
||
#+end_src
|
||
|
||
Lastly, when I want to copy a file, I just hit the ~y~ key for “yank”
|
||
(that’s a term from Emacs). For that, I rely on ~file~ to tell me the
|
||
mimetype of the image, then I can pass it to ~xclip~ along with the
|
||
filename to copy it to the clipboard. In this case, we only copy the
|
||
first of the selected files since the clipboard cannot hold several
|
||
files at once.
|
||
#+name: nsxiv-yank
|
||
#+begin_src fish
|
||
case "y"
|
||
set FILE "$FILES[1]"
|
||
set TYPE (file -i "$FILE" | sed -r 's|.*(image/[a-z]+);.*|\1|')
|
||
xclip -sel clip -t "$TYPE" -i "$FILE"
|
||
#+end_src
|
||

** Toggle touchpad tapping

:HEADER-ARGS: :shebang "#!/usr/bin/env fish" :mkdirp yes :tangle ~/.local/bin/tttapping
|
||
:CUSTOM_ID: Toggle_touchpad_tapping-23348b00
|
||
:END:
|
||
For some reasons, my firmware does not recognize the function key for toggling
|
||
the touchpad. I’m not going to really complain about it since it lets me program
|
||
it like I want. Since I often don’t need to completely deactivate the touchpad,
|
||
I’ll instead toggle whether tapping is enabled or not when pressing
|
||
~XF86TouchpadToggle~. And for that, I need this small script that will actually
|
||
toggle it, and it will be used in my window manager configuration.
|
||
|
||
First let’s declare some variables to make this script more personal. With my
|
||
current computer (a Gazelle by System76), the name of my touchpad is the
|
||
following:
|
||
#+BEGIN_SRC fish
|
||
set TPNAME "ELAN0412:00 04F3:3162 Touchpad"
|
||
#+END_SRC
|
||
|
||
Let’s now get the identifier of the touchpad for ~xinput~:
|
||
#+BEGIN_SRC fish
|
||
set TPID (xinput list | grep $TPNAME | awk '{print $6}' | sed 's|id=\(.*\)|\1|g')
|
||
#+END_SRC
|
||
|
||
Now, let’s detect the current status of the touchpad:
|
||
#+BEGIN_SRC fish
|
||
set TPSTATUS (xinput list-props $TPID | grep "Tapping Enabled" | \
|
||
grep -v "Default" | awk '{print $5}')
|
||
#+END_SRC
|
||
|
||
This will set ~TPSTATUS~ either to ~0~, meaning tapping is disabled, or to ~1~,
|
||
meaning it’s enabled. I will consider any other value as being disabled.
|
||
#+BEGIN_SRC fish
|
||
test [[ $TPSTATUS = "1" ]] && set NEWTPSTATUS 0 || set NEWTPSTATUS 1
|
||
#+END_SRC
|
||
|
||
Finally, let’s update the touchpad’s options:
|
||
#+BEGIN_SRC fish
|
||
xinput set-prop $TPNAME "libinput Tapping Enabled" $NEWTPSTATUS
|
||
#+END_SRC

This script is a wrapper around ~youtube-dl~ which I use mainly for
|
||
archiving YouTube videos on my NAS (at the time I’m writing this, I
|
||
have already 2.1 TB worth of videos archived). The principle behind
|
||
this script is quite simple: I want to avoid as much as possible to
|
||
redownload any video already downloaded in order to avoid pinging too
|
||
much YouTube’s servers, 429 Too Many Requests errors are really
|
||
annoying, and it comes really early when you have only a couple of new
|
||
videos to download among the few 14k videos already downloaded.
|
||
|
||
Be aware this script was written for the Fish shell (3.1.0 and above), and makes
|
||
use of youtube-dl 2020.03.24 and above, [[https://github.com/jorgebucaran/fish-getopts][Fish getopts]] and [[https://github.com/BurntSushi/ripgrep][ripgrep]].

In order to download a single video, a simple function has been written for this
|
||
that will display when downloaded how far it is down the list of videos to be
|
||
downloaded and it will add its ID to the file listing all videos downloaded. The
|
||
script will also try to download the video according to the ~PREFFERED_FORMAT~
|
||
variable, but if the download fails it will download the default format selected
|
||
by ~youtube-dl~. If both downloads fail, the ID of the video will be added to
|
||
the list of failed videos. If one of the downloads succeeds, it will remove the
|
||
ID from the list of failed downloads.
|
||
|
||
The first argument of the function is the video ID from YouTube, the second
|
||
argument is the position of the video in the queue, and the third argument is
|
||
the queue length –can be the amount of videos in a whole YouTube channel, the
|
||
amount of videos in a playlist, or simply the amount of YouTube URLs passed as
|
||
arguments to the script.

The final function to declare before the main body of the script is
|

~_ytdl_download_batch~: it will look for each line, ignoring the ones beginning

by ~#~, ~;~ and ~]~ (just like ~youtube-dl~) and will download them, assuming
|
||
these are channel URLs or playlist URLs, however it should also work with direct
|
||
video URLs.
|
||
|
||
What this function does is for each line, it will fetch the entierty of the
|
||
video IDs found in a playlist or channel. Then, it will look each ID up the list
|
||
of already downloaded videos and will add all new IDs to a queue of videos to be
|
||
downloaded. It will then pass each new video ID to ~_ytdl_download_video~
|
||
directly. Beware that if you pass directly the URL of the channel, such as
|
||
~https://www.youtube.com/user/enyay~ if you want to download Tom Scott’s videos,
|
||
it will download everything on the main page of their channel, which means it
|
||
will even download videos from playlists they decided to put on their channel’s
|
||
front page, even if it is not theirs. So in that case, we need to append
|
||
~/videos~ to any channel URL.

~awiki~ is a simple script used with ~rofi~ that relies on the ~arch-wiki-docs~
|
||
package in order to provide the user a way to quickly find and display any
|
||
English page from the Arch Wiki in a browser. The advantage of using this over
|
||
the ~wiki-search~ utility from the ~arch-wiki-lite~ package is you get instant
|
||
suggestion in rofi using fuzzy-search. The downside is rofi will only help you
|
||
find pages by their title, and it will not help you find keywords in the content
|
||
of said pages.
|
||
|
||
The first step is to create the list of all the pages that are currently stored
|
||
on disk. ~arch-wiki-docs~ stores them in ~/usr/share/doc/arch-wiki/html/en~. A
|
||
simple ~ls~ piped in three ~sed~ will give us a list of page titles. We then
|
||
pipe that into rofi in dmenu mode in order to choose the page we want to
|
||
display. By the way, setting the location of the HTML files will come in handy
|
||
later.
|
||
#+BEGIN_SRC fish

||
set WLOCATION /usr/share/doc/arch-wiki/html/en/

set WPAGE (echo $WPAGE | sed -r 's/\s+/_/g')
|
||
#+END_SRC

Now, all I need to do is to send this list into rofi and tell it to open the
|
||
result with our favorite browser with ~xdg-open~.

~connect-wifi~ is a small utility tool that allows the user to connect to

Now, let’s declare a function that will allow us to chose the drive we want to
|
||
mount.
|
||
#+BEGIN_SRC fish
|
||
function getmount
|
||
#+END_SRC
|
||
|
||
First, we want to get our mount point. We’ll run a =find= command on each of the
|
||
directories listed in =$basemount= to look for folders on which our drive could
|
||
be mounted. This list will be passed to rofi from which we will chose our mount
|
||
point.
|
||
#+BEGIN_SRC fish
|
||
set -g mp (for d in $basemount
|
||
find $d -maxdepth 5 -type d
|
||
end | rofi -dmenu -i -p 'Type in mount point.')
|
||
#+END_SRC
|
||
|
||
We should verify that something has been actually selected, otherwise we should
|
||
abort the script.
|
||
#+BEGIN_SRC fish
|
||
if test -z $mp || test $mp = ""
|
||
return 1
|
||
end
|
||
#+END_SRC
|
||
|
||
Now, if the selected mount point does not exist, we’ll ask the user whether the
|
||
directory should be created. If no, the script will abort. If yes, an attempt
|
||
will be made at creating the directory as the user; if that fails, a new attempt
|
||
will be made as sudo.
|
||
#+BEGIN_SRC fish
|
||
if test ! -d $mp
|
||
switch (printf "No\\nYes" | rofi -dmenu -i -p "$mp does not exist. Create it?")
|
||
case 'Yes'
|
||
mkdir -p $mp || sudo -A mkdir -p $mp
|
||
case '*'
|
||
return 1
|
||
end
|
||
end
|
||
#+END_SRC
|

Finally, let’s close the function
|

#+BEGIN_SRC fish

|

:END:
|
||
Alright, we want to mount a partition that answers by the name of =/dev/sdXX=,
|
||
how do we do that? Let’s create first the function =mountusb= that will take
|
||
care of it for us.
|
||
#+BEGIN_SRC fish
|
||
function mountusb
|
||
#+END_SRC
|
||
|
||
Now, the first thing we want to do is select the partition we want to mount.
|
||
Remember, we stored those in =$usbdrives= earlier, so let’s pipe them into rofi
|
||
so we can chose from it. Also, =awk= will get their path in =/dev=.
|
||
#+BEGIN_SRC fish
|
||
set -g chosen (echo $usbdrives | \
|
||
rofi -dmenu -i -p "Mount which drive?" | \
|
||
awk '{print $1}')
|
||
#+END_SRC
|
||
|
||
As usual after a user selection, let’s verify something has actually been
|
||
selected. If not, let’s abort the script.
|
||
#+BEGIN_SRC fish
|
||
test -z $chosen && return 1
|
||
#+END_SRC
|
||
|
||
Now, let’s select the mount point of our partition. We’ll call the function
|
||
=getmount= described in [[#Rofi-mount-Get_the_mount_point-6c4bac06][Get the mount point]] to select it.
|
||
#+BEGIN_SRC fish
|
||
getmount
|
||
#+END_SRC
|
||
|
||
Let’s verify the variable =mp= set in =getmount= is not empty, otherwise abort
|
||
the script.
|
||
#+BEGIN_SRC fish
|
||
test -z $mp && return 1
|
||
#+END_SRC
|
||
|
||
Now, let’s mount it! We’ll use a switch which will detect the filesystem used so
|
||
we know how to mount the partition.
|
||
#+BEGIN_SRC fish
|
||
switch (lsblk -no "fstype" $chosen)
|
||
#+END_SRC
|
||
|
||
We have two named case: =vfat= filesystems.
|
||
#+BEGIN_SRC fish
|
||
case "vfat"
|
||
sudo -A mount -t vfat $chosen $mp -o rw,umask=0000
|
||
#+END_SRC
|
||
|
||
And =ntfs= filesystems.
|
||
#+BEGIN_SRC fish
|
||
case "ntfs"
|
||
sudo -A mount -t ntfs $chosen $mp -o rw,umask=0000
|
||
#+END_SRC
|
||
|
||
Else, we’ll let =mount= determine which filesystem is used by the partition
|
||
(generally =ext4=).
|
||
#+BEGIN_SRC fish
|
||
case '*'
|
||
sudo -A mount $chosen $mp
|
||
#+END_SRC
|
||
|
||
We’ll also run a =chown= on this newly mounted filesystem so the user can access
|
||
it without any issues.
|
||
#+BEGIN_SRC fish
|
||
sudo -A chown -R $USER:(id -g $USER) $mp
|
||
#+END_SRC
|
||
|
||
Let’s close the switch block and send a notification the partition has been
|
||
mounted.
|
||
#+BEGIN_SRC fish
|
||
end && notify-send -a "dmount" "💻 USB mounting" "$chosen mounted to $mp."
|
||
#+END_SRC
|
||
|

And let’s close the function.

The function that manages to mount Android filesystems is =mountandroid=. Let’s
|

declare it.
|
||
#+BEGIN_SRC fish
|
||
function mountandroid -d "Mount an Android device"
|

#+END_SRC
|

We’ll select which Android we want to mount. We will be asked through rofi.
|

#+BEGIN_SRC fish
|

set chosen (echo $anddrives | rofi -dmenu -i -p "Which Android device?" | awk '{print $1 $2}' | sed 's/,$//')
|
||
#+END_SRC
|
||
|
||
Now, we need to get the bus of the Android device we want to mount. It will be
|
||
useful later, after we authorized mounting from our device, to get the path to
|
||
our partition.
|
||
#+BEGIN_SRC fish
|
||
set bus (echo $chosen | sed 's/,.*//')
|
||
#+END_SRC
|
||
|

Let’s temporarily mount our device.
|
||
#+BEGIN_SRC fish
|
||
jmtpfs -device=$chosen $mp
|
||
#+END_SRC
|
||
|
||
Now, we need to allow our computer to mount our Android device. Depending on the
|
||
Android version it is running on, we either need to specify our device is USB
|
||
connected in order to exchange files, or Android will explicitely ask us if it
|
||
is OK for our computer to access it. Let’s inform the user of that.
|
||
#+BEGIN_SRC fish
|
||
echo "OK" | \
|

rofi -dmenu -i -p "Press (Allow) on your phone screen, or set your USB settings to allow file transfert"
|
||
#+END_SRC
|
||
|

Now, let’s get the actual path of our Android filesystem we wish to mount, and
|
||
let’s unmount the previous temporary filesystem.
|
||
#+BEGIN_SRC fish
|
||
set newchosen (jmtpfs -l | grep $bus | awk '{print $1 $2}' | sed 's/,$//')
|
||
sudo -A umount $mp
|
||
#+END_SRC
|
||
|
||
Now we cam mount the new filesystem and send a notification if everything went
|
||
well.
|
||
#+BEGIN_SRC fish
|
||
jmtpfs -device=$newchosen $mp && \
|
||
notify-send -a "dmount" "🤖 Android Mounting" "Android device mounted to $mp."
|
||
#+END_SRC
|
||
|

And now, we can close our function.

|

#+BEGIN_SRC fish

set chosen (echo $cddrives | rofi -dmenu -i -p "Which CD drive?")

We’ll also get the mountpoint thanks to the =getmount= function described

earlier.
|

#+BEGIN_SRC fish

getmount

sudo -A mount $chosen $mp && \

|

#+BEGIN_SRC fish

function asktype

We will use a switch statement which will use our anwser to rofi about what we

#+BEGIN_SRC fish

switch (cat $TMPDRIVES | rofi -dmenu -i -p "Mount which drive?")

|

If we chose the option "USB", we’ll mount a hard drive, partition or USB drive.

In which case we’ll call the =mountusb= function.
|

#+BEGIN_SRC fish
|

case "USB"
|

mountusb
|

#+END_SRC

If we chose the "Android" option, the =mountandroid= function is called.

#+BEGIN_SRC fish

case "Android"

Else if we chose the "CD" option, we’ll call the =mountcd= function.

#+BEGIN_SRC fish

case "CD"
|

mountcd

|

=rofi-pass= is a simple utility that gets a password stored in the [[https://www.passwordstore.org/][=pass=]]
|
||
password manager with rofi as its interface, and then stores the password in the
|
||
clipboard.
|
||
|
||
Let’s parse all the arguments passed to the script. If one of them is =--type=,
|
||
=-t= or =type=, the script will attempt to type the password to the text area
|
||
already selected without pasting the password to the clipboard.
|
||
#+BEGIN_SRC fish
|
||
for arg in $argv
|
||
switch $arg
|
||
case '--type' '-t' 'type'
|
||
set -g TYPE "yes"

exit 1
|
||
end
|
||
end
|
||
#+END_SRC
|
||
|
||
Now, let’s get the list of the passwords that exist in our =pass= repository.
|
||
#+BEGIN_SRC fish
|
||
set passwords (find $HOME/.password-store -type f -name "*.gpg" | \
|
||
string replace -r ".*.password-store/" "" | \
|
||
string replace -r ".gpg" "" | sort)
|
||
#+END_SRC
|
||
|
||
Let the user choose which password they wish to select.
|
||
#+BEGIN_SRC fish
|
||
set password (for elem in $passwords
|
||
echo $elem
|
||
end | rofi -dmenu -i -p "Select your password")
|
||
#+END_SRC
|
||
|
||
Let’s verify we actually selected a password and not just exited. If no password
|
||
was selected, let’s simply exit the script.
|
||
#+BEGIN_SRC fish
|
||
if test -z $password
|
||
exit
|
||
end
|
||
#+END_SRC
|
||
|
||
Depending on the arguments passed earlier, we might want some different
|
||
behavior.
|
||
#+BEGIN_SRC fish :noweb yes
|
||
if test $TYPE = "yes"
|
||
<<rofi-pass-type>>
|
||
else
|
||
<<rofi-pass-copy>>
|
||
end
|
||
#+END_SRC
|
||
|
||
The default behavior is to copy the password to the clipboard for 45 seconds, so
|
||
let’s do that.
|
||
#+NAME: rofi-pass-copy
|
||
#+BEGIN_SRC fish :noweb yes :tangle no
|
||
pass show -c $password 2> /dev/null
|
||
#+END_SRC
|
||
|
||
Else, if we passed =--type=, =-t= or =type= as an argument of the script, we
|
||
want it to attempt to type our password in the currently selected text input.
|
||
Let’s do that.
|
||
#+NAME: rofi-pass-type
|
||
#+BEGIN_SRC fish :noweb yes :tangle no
|
||
set -l IFS
|
||
<<rofi-pass-type-get-password>>
|
||
printf %s $pass | xvkbd -file -
|
||
#+END_SRC
|
||
|
||
To correctly get the password from ~pass~, we need to parse the output and only
|
||
get the first line, hence the following command.
|
||
#+NAME: rofi-pass-type-get-password
|
||
#+BEGIN_SRC fish :tangle no
|
||
set pass (pass show $password | string split -n \n)[1]

This is just a simple wrapper around [[#ytdl-a-youtube-dl-wrapper-03bd63e0][ytdl]] so I can easily download a video from

Now, if the variable ~URL~ is not empty (i.e. the user specified a link and did
|
||
not abort the operation), we’ll proceed to teh download. Before it begins, we’ll
|
||
send a notification saying the download is about to begin. When the ~ytdl~
|
||
process ends, we’ll also send a notification notifying the user on the success
|
||
or failure of the download.

Below is the script I use to display information in sway’s bar. It is
|
||
divided by functions that are then called all together. First, getting
|
||
the date is quite straightforward.
|
||
#+begin_src sh
|
||
sb_date() {
|
||
echo "$(date +'%Y-%m-%d %H:%M:%S') | "
|
||
}
|

#+end_src
|
||
|
||
Then we can get what piece of audio is playing. Note however that
|
||
something will be displayed only if something is playing.
|
||
#+begin_src sh
|
||
sb_playerctl() {
|
||
PLAYING=""
|
||
if [ "$(playerctl status)" = "Playing" ]; then
|
||
PLAYING_ARTIST="$(playerctl metadata xesam:artist)"
|
||
PLAYING_TITLE="$(playerctl metadata xesam:title)"
|
||
PLAYING=" $PLAYING_ARTIST - $PLAYING_TITLE | "
|
||
fi
|
||
echo "$PLAYING"
|
||
}
|
||
#+end_src
|
||
|
||
The battery is relatively straightforward too. I should however find
|
||
how to get estimates of battery time. I’m sure I can come up with
|
||
something, but for now I’m just too lazy.
|
||
#+begin_src sh
|
||
sb_battery() {
|
||
CAPACITY="$(cat /sys/class/power_supply/BAT0/capacity)%"
|
||
STATE="$(cat /sys/class/power_supply/BAT0/status)"
|
||
echo "$CAPACITY ($STATE)"
|
||
}
|
||
#+end_src
|
||
|
||
Now comes an indicator for Docker containers which will be displayed
|
||
only if at least one is running.
|
||
#+begin_src sh
|
||
sb_docker() {
|
||
DOCKER_RUNNING="$(docker ps -q | wc -l)"
|
||
# echo "Docker: $DOCKER_RUNNING"
|
||
if [ "$DOCKER_RUNNING" = "0" ]
|
||
then echo ""
|
||
else echo "Docker: $DOCKER_RUNNING | "
|
||
fi
|
||
}
|
||
#+end_src
|
||
|
||
Finally, let’s display everything.
|
||
#+begin_src sh
|
||
echo "$(sb_docker)$(sb_playerctl)$(sb_date)$(sb_battery) "
|
||
#+end_src
