Due to a recent bug, StumpWM crashes if the screen layout is reorganized in its configuration file (maybe not just then, I’ll have to check). Thus, this commit removes calls to xrandr and autorandr from my WM configurations and moves them to their respective xinitrc file. It also removes the `set-screens` script in my scripts collection as it became obsolete the moment I began using `autorandr` instead. It also removes the call to `xsetroot` in my StumpWM config since it is redundant with its xinitrc file.

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")

=cppnew= is a small utility that helps you create a new C++ project. Several
|
||
templates are available, the default one using CMake, and three others that are
|
||
a bit more advances, based on:
|
||
- CMake + [[https://conan.io/][Conan]]
|
||
- [[https://mesonbuild.com/][Meson]] + [[https://ninja-build.org/][Ninja]]
|
||
- Meson + Ninja + Conan
|
||
There is also a default [[http://doxygen.nl/][Doxygen]] file included for your documentation, ready to
|
||
go. I even made it so that you can execute it as an executable file, like
|
||
=./doc/Doxyfile= from the project root.
|
||
|
||
The choice is given to the user which of them to use with options that will be
|
||
given to =cppnew=.
|
||
|
||
First of all, if no arguments were passed, return an error.
|
||
#+begin_src fish
|
||
if ! count $argv >/dev/null
|
||
echo "Missing argument: PROJECT" && return -1
|
||
end
|
||
#+end_src
|
||
|
||
Now, let’s set a couple of variables which will prove useful later on when
|
||
trying to set up our project.
|
||
|
||
*** Cnew
|
||
:PROPERTIES:
|
||
:HEADER-ARGS: :shebang "#!/usr/bin/env fish" :mkdirp yes :tangle ~/.local/bin/cnew
|
||
:CUSTOM_ID: Cnew-d9ec9cc4
|
||
:END:
|
||
=cnew= is a small utility script similar to but simpler than cppnew that creates
|
||
a CMake template C project from the template that already exists in
|
||
[[file:~/dev/templateC][~/dev/templateC]]. If no argument was passed, display an error message and exit.
|
||
#+BEGIN_SRC fish
|
||
if ! count $argv > /dev/null
|
||
echo "Missing argument: PROJECT" && return -1
|
||
end
|
||
#+END_SRC
|
||
|
||
Pass the first argument to a switch statement.
|
||
#+BEGIN_SRC fish
|
||
switch "$argv[1]"
|
||
#+END_SRC
|
||
|
||
If the argument is =-h= or =--help=, then display the help message and exit the
|
||
script normally.
|
||
#+BEGIN_SRC fish
|
||
case -h --help
|
||
man ~/dev/fishfunctions/cnew.man
|
||
exit 0
|
||
#+END_SRC
|
||
|
||
Else, the argument is the name of the project the user wants to create.
|
||
#+BEGIN_SRC fish
|
||
case '*'
|
||
set -g project_name $argv[1]
|
||
#+END_SRC
|
||
|
||
Let’s close the switch statement.
|
||
#+BEGIN_SRC fish
|
||
end
|
||
#+END_SRC
|
||
|
||
Now, let’s copy the template where the user is executing =cnew= from, give it
|
||
the name of the project and move to the project.
|
||
#+BEGIN_SRC fish
|
||
cp -r ~/dev/templateC $argv[1]
|
||
cd $argv[1]
|
||
#+END_SRC
|
||
|
||
The default files have a placeholder for the name of the project. Let’s replace
|
||
these placeholders with the project’s name.
|
||
#+BEGIN_SRC fish
|
||
sed -i "s/PROJECTNAME/$argv[1]/g" CMakeLists.txt
|
||
sed -i "s/PROJECTNAME/$argv[1]/g" README.org
|
||
sed -i "s/CPROJECTNAME/$argv[1]/g" doc/Doxyfile
|
||
#+END_SRC
|
||
|
||
Now, let’s create a git repository and initialize it.
|
||
#+BEGIN_SRC fish
|
||
git init
|
||
git add .
|
||
git commit -m "initial commit"
|
||
#+END_SRC
|
||
|
||
And we’re done!
|
||
|
||
*** Dart Language Server

||
:CUSTOM_ID: Dart_Language_Server-18c256b1
|
||
:END:
|
||
Spacemacs' recommendations on how to use Dart with LSP is outdated, since
|
||
[[https://github.com/natebosch/dart_language_server][=dart_language_server=]] is obsolete. As recommended by the repo owner, we should
|
||
launch instead the following code:
|
||
#+BEGIN_SRC fish
|
||
/usr/bin/dart $DART_SDK/snapshots/analysis_server.dart.snapshot --lsp
|
||
#+END_SRC
|
||
|
||
So, instead of using the obsolete executable, instead we will be calling the
|
||
analysis server as requested.
|
||
|
||

This is a simple utility to be ran when the ~flutter~ package is updated.
|
||
#+BEGIN_SRC fish

:END:
|
||
~mu-unread~ is a very simple utility that simply returns the amount of
|
||
unread emails I have through the use of ~mu~.
|
||
|
||
As you can see, the output string contains two font switchers for
|
||
StumpWM so I can switch from the main font to Siji for the caracter
|
||
contained between them: U+E072 (an email icon).
|
||
#+begin_src sh
|
||
UNREAD=$(mu find "flag:unread AND (maildir:/Inbox OR maildir:/Junk)" | wc -l)
|
||
printf "^f2^f0%s" "$UNREAD"

~pinfo~ is a utility that shows system information

:END:
|
||
It is possible to call a script on the resulting image of a ~scrot~
|
||
command. Not only do I want to move them to a specific directory, I
|
||
also want to be able to see them in ~nsxiv~ (a replacement for ~sxiv~) in
|
||
case I want to edit the image, copy it or simply delete it (sometimes
|
||
I take screenshots by accident).

||
#+begin_src sh

:END:
|
||
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 port of a remote machine,
|
||
and vice versa. The syntax is actually very simple, but I prefer a more
|
||
intuitive way of writing it. Its usage is ~sshbind PORT FROMHOST TOHOST~.
|
||
#+BEGIN_SRC fish

|

:END:
|
||
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
|
||
#+begin_src fish

<<nsxiv-read-files>>
|
||
|
||
<<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" $FILES
|
||
end
|
||
#+end_src
|
||
|
||
We can then read from the first member of ~argv~ which key the user
|
||
pressed. Depending on it, we can chose what to execute.
|
||
#+name: nsxiv-switch-statement
|
||
#+begin_src fish
|
||
switch "$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

|
||
: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 2.1TB
|
||
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]].

~_ytdl_log~ is a very simple function used for logging information for the user

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, 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

|

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
|

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

declare it.
|

#+BEGIN_SRC fish

function mountandroid -d "Mount an Android device"

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
|

#+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.

|

=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"
|
||
case '*'
|
||
printf 'Unknown argument: %s\n.' $arg
|
||
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]
|
||
#+END_SRC

||

||

This is just a simple wrapper around [[#ytdl-a-youtube-dl-wrapper-03bd63e0][ytdl]] so I can easily download a video from
|
||
rofi, which we’ll use first to retrieve the URL of the video we want to
|
||
download, be it from YouTube or other website supported by ~youtube-dl~.
|
||
#+BEGIN_SRC bash
|
||
URL=$(echo "Video to download:" | rofi -dmenu -i -p "Video to download:")
|
||
#+END_SRC
|
||
|
||
Now, if the variable ~URL~ is not empty (i.e. the user specified a link and did
|
||
not abort the operation), we’ll proceed to teh download. Before it begins, we’ll
|
||
send a notification saying the download is about to begin. When the ~ytdl~
|
||
process ends, we’ll also send a notification notifying the user on the success
|
||
or failure of the download.
|
||
#+BEGIN_SRC bash
|
||
if [ -n "$URL" ]; then
|
||
notify-send -u normal "YTDL" "Starting downloading\n$URL"
|
||
if [[ $(ytdl "$URL") ]]
|
||
then
|
||
notify-send -u normal "YTDL" "Finished downloading!"
|
||
else
|
||
notify-send -u critical "YTDL" "Failed downloading\n$URL"

This utility is not meant to be called by the user directly, but rather by
|
||
scripts that may be written by the user. Its role is simple: check if the
|
||
provided wallpaper exists and if it is an image. If both requirements are met,
|
||
the path to this image is then stored in ~$XDG_CACHE_HOME/wallpaper~, or if this
|
||
variable is empty in ~$HOME/.cache/wallpaper~.

#+BEGIN_SRC sh

A quick and useful script I often use is a ~curl~ request to [[http://v2.wttr.in/][v2.wttr.in]] to get a
|
||
weather forecast in the terminal. By default, I want the request to be about the
|
||
city I live in, but it is also possible for the script to accept as its
|
||
arguments a search inquiry.
|
||
#+BEGIN_SRC fish
|
||
if count $argv > /dev/null
|
||
set -l SEARCH (string join '+' $argv)
