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.

=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
|
||
:PROPERTIES:
|
||
:HEADER-ARGS: :shebang "#!/usr/bin/env fish" :mkdirp yes :tangle ~/.local/bin/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.
|
||
|
||
*** UpdateFlutter
|
||

||

|
||
:CUSTOM_ID: UpdateFlutter-1e8fbeb7
|
||
:END:
|
||
This is a simple utility to be ran when the ~flutter~ package is updated.
|
||
#+BEGIN_SRC fish
|
||

|
||
:END:
|
||
~set-screens~ is a small script that allows the user to automatically set up an external monitor. First, let’s set some variables so we don’t have to type in hidden places some values that should be easily modifiable.
|
||
#+BEGIN_SRC fish
|
||
set internal "eDP1"
|
||
set external "HDMI1"
|
||
#+END_SRC
|
||
|
||
Now, let’s set the ~DETECTEDSCREEN~ variable with a simple ~grep~. If the variable turns out to be empty, this means the display was not detected. However, if it’s not, then it will be an array with its second value that holds the maximum resolution the display can handle. It needs to be passed through ~awk~ in order to get only the resolution itself and not the refresh rate, but once we’ve got that, we can set our external monitor as the main monitor with its maximum resolution. i3 is also restarted in order to properly display the wallpaper and Polybar on the new screen.
|
||
#+BEGIN_SRC fish
|
||
set externaldisplay (xrandr -q --current | grep -A 1 -i "$external connected")
|
||
if test -n "$externaldisplay"
|
||
set resolution (echo $externaldisplay[2] | awk '{$1=$1;print $1}')
|
||
xrandr --output "$external" --primary --auto --mode "$resolution" --right-of "$internal"
|
||
end
|
||
#+END_SRC
|
||
|
||
** sshbind
|
||

|
||
:HEADER-ARGS: :shebang "#!/usr/bin/env fish" :mkdirp yes :tangle ~/.local/bin/sshbind
|
||
:CUSTOM_ID: sshbind-756fabb1
|
||
: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
|
||
ssh -L $argv[1]:$argv[3]:$argv[1] $argv[2] -N
|
||
#+END_SRC

** Starwars
|

|
||
:HEADER-ARGS: :shebang "#!/usr/bin/env fish" :mkdirp yes :tangle ~/.local/bin/starwars
|
||
:CUSTOM_ID: Starwars-654f8637
|
||
:END:
|
||
This is a one-liner that allows you to watch Star Wars episode 4 in ASCII art in your terminal. Here is the code:
|
||
#+BEGIN_SRC fish
|
||
telnet towel.blinkenlights.nl
|
||
#+END_SRC
|
||
|
||
** Toggle touchpad tapping
|
||
:PROPERTIES:
|
||
: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
|
||
|
||
** Wacom setup

I made a small and quick utility to set up my Wacom tablet so it is only bound to one screen.

||
:CUSTOM_ID: Wacom_setup-Set_our_variables-3cb6d58e

Let’s first declare our function that will be called to set our variables.
|
||
#+BEGIN_SRC fish
|
||
function set_device
|
||
#+END_SRC
|
||
|
||
We need some variables in order to correctly set our tablet. First, let’s get declare what the name of our tablet is, and what the name of its touchpad is.
|
||
#+BEGIN_SRC fish
|
||
set -g DEVICE "Wacom USB Bamboo PAD Pen stylus"
|
||
set -g DEVICETOUCH "Wacom USB Bamboo PAD Finger touch"
|
||
#+END_SRC
|
||
|
||
We will also modify two settings: the speed of the cursor on the touchpad, and the scroll speed. Let’s declare the name of these two settings.
|
||
#+BEGIN_SRC fish
|
||
set -g WACOMPROPTOUCHSPEED "Device Accel Velocity Scaling"
|
||
set -g WACOMPROPSCROLLPSEED "ScrollDistance"
|
||
#+END_SRC
|
||
|
||
To get the correct values for the area it can cover, we’ll need to reset our tablet.
|
||
#+BEGIN_SRC fish
|
||
xsetwacom set "$DEVICE" ResetArea
|
||
#+END_SRC
|
||
|
||
Now we can get the X and Y areas.
|
||
#+BEGIN_SRC fish
|
||
set -l AREATOT (xsetwacom get "$DEVICE" Area)
|
||
set -g AREAX (echo $AREATOT | awk '{print $3}')
|
||
set -g AREAY (echo $AREATOT | awk '{print $4}')
|
||
#+END_SRC
|
||
|
||
Now let’s close our function.
|
||
#+BEGIN_SRC fish
|

end
|

#+END_SRC
|
||
|

*** Select our screen

:PROPERTIES:

||
:CUSTOM_ID: Wacom_setup-Select_our_screen-7822c0c3
|

This function will allow us to select the screen on which the tablet will be active. We can also select the option “desktop” so that all screens are selected. Let’s declare our function.
|
||
#+BEGIN_SRC fish
|
||
function set_screen
|
||
#+END_SRC
|
||
|
||
First, let’s set what screens are available, including the desktop option.
|
||
#+BEGIN_SRC fish
|
||
set CONNECTED_DISPLAYS (xrandr -q --current | \
|
||
sed -n 's/^\([^ ]\+\) connected .*/\1/p') desktop
|
||
#+END_SRC
|
||
|
||
Now, let’s select the one we wish to use using rofi.
|
||
#+BEGIN_SRC fish
|
||
set -g SCREEN (for d in $CONNECTED_DISPLAYS
|
||
echo $d
|
||
end | rofi -dmenu -i -p "Select your dispaly" | tr -d '\n')
|
||
#+END_SRC
|
||
|
||
Now, let’s get the resolution of our selected screen.
|
||
#+BEGIN_SRC fish
|
||
set -l LINE (xrandr -q --current | if [ "$SCREEN" = "desktop" ]
|
||
sed -n 's/^Screen 0:.*, current \([0-9]\+\) x \([0-9]\+\),.*/\1 \2/p'
|
||
else
|
||
sed -n "s/^$SCREEN"' connected \(primary \)\{0,1\}\([0-9]\+\)x\([0-9]\+\)+.*/\2 \3/p'
|
||
end)
|
||
#+END_SRC
|
||
|
||
From that, let’s get the vertical and horizontal resolution of our screen.
|
||
#+BEGIN_SRC fish
|
||
echo $LINE | read -g WIDTH HEIGHT
|
||
#+END_SRC
|
||
|
||
If any of our ~WIDTH~ ou ~HEIGHT~ it empty, we’ll have to abort the script.
|
||
#+BEGIN_SRC fish
|
||
if test -z $WIDTH || test -z $HEIGHT
|
||
exit 1
|
||
end
|
||
#+END_SRC
|
||
|
||
Let’s close our function now.
|
||
#+BEGIN_SRC fish
|
||
end
|
||
#+END_SRC
|
||
|

*** Adjust the tablet

This function will take care of adjusting our tablet to our screen. Let’s declare our function.
|
||
#+BEGIN_SRC fish
|
||
function adjust_device
|
||
#+END_SRC
|
||
|
||
If our screen is too high or too wide for our tablet, we will have to adjust the height or width of the area used by the tablet. So let’s get the theoretical new height and width of the area.
|
||
#+BEGIN_SRC fish
|
||
set RATIOAREAY (math ceil \($AREAX \* $HEIGHT \/ $WIDTH\))
|
||
set RATIOAREAX (math ceil \($AREAY \* $WIDTH \/ $HEIGHT\))
|
||
#+END_SRC
|
||
|
||
Now, if the current height of the tablet’s area is greater than the theoretical new area, it means the current area is too high. Otherwise, it should be the other way around. Let’s set =NEWAREAX= and =NEWAREAY= that will be used to set the new area for the tablet.
|
||
#+BEGIN_SRC fish
|
||
if test $AREAY -gt $RATIOAREAY
|
||
set -g NEWAREAX $AREAX
|

|
||
set -g NEWAREAY $AREAY
|
||
end
|
||
#+END_SRC
|

Alright, now let’s set the new area with these new variables.
|
||
#+BEGIN_SRC fish
|
||
xsetwacom set "$DEVICE" Area 0 0 $NEWAREAX $NEWAREAY
|
||
xsetwacom set "$DEVICE" MapToOutput "$SCREEN"

#+END_SRC
|

Let’s slow down the cursor’s speed on the touchpad.

xinput set-float-prop $DEVICETOUCH $WACOMPROPTOUCHSPEED 0.5
|

Let’s also slow down the scroll speed of the touchpad.
|
||
#+BEGIN_SRC fish
|

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]].

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.

Now that we have all our functions declared, let’s call them! First, we need to parse our arguments. We’ll then download all files passed as arguments. Finally, we’ll download videos, playlists and channels specified from a batch file.

And that’s all! If you’re interested with a very simple interface for downloading one video once, I wrote a small [[#rofi-ytdl-ff8f789d][~rofi-ytdl~]] script that calls the ~rofi~ utility to specify a single link and download it.

Now that our system isn’t running polybar anymore, we’ll launch it again on all of our screens. By the way, I have two bars, so I’ll have to lauch them both.

Askpass is a simple script that invokes ~rofi~ as a way to get from a GUI the user’s sudo password. It is inspired by [[https://github.com/ODEX-TOS/tools/blob/master/rofi/askpass][this original tool]], rewritten in fish and with [[https://wiki.archlinux.org/index.php/Rofi][rofi]] support instead of [[https://wiki.archlinux.org/index.php/Dmenu][dmenu]].

:END:
|
||
~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 (/bin/ls $WLOCATION | \
|

|
||
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 available WiFi networks. The first thing to do is to select the WiFi we want to connect to. We’ll use the ~nmcli c s~ command to get the list of the available networks, and we’ll chose one with ~rofi~.

The emoji picker is a simple fish script that uses rofi and [[file:~/.config/emoji.txt][~/.config/emoji.txt]] to provide a small, local search for emojis. Once the emoji is selected, it is copied to the clipboard using =xclipboard=.

What the script does first is detect everything that can be mounted. Between a =begin= and =end=, let’s set =LFS= as a local variable. This si in order to get sane variables in the current block.

Now, let’s detect the amount of mountable Android filesystems, and if any are detected, let’s read them into a global variable.

set -l a (math (jmtpfs -l | wc -l) - 2)

Alright, we’ll save what kind on drives we can mount in a temporary file called =/tmp/drives=. We’ll make sure it’s blank by erasing it then creating it again with =touch=, like so. The =-f= flag on =rm= is here so we get no error if we try to delete a file that doesn’t exist (yet).

|

#+BEGIN_SRC fish

#+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

We should verify that something has been actually selected, otherwise we should abort the script.

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.

|

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=.

test -z $chosen && return 1

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

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)

sudo -A mount -t vfat $chosen $mp -o rw,umask=0000

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
|

sudo -A chown -R $USER:(id -g $USER) $mp
|

Let’s close the switch block and send a notification the partition has been mounted.

end && notify-send -a "dmount" "💻 USB mounting" "$chosen mounted to $mp."

Now, we need to allow our computer to mount our Android device.

The first thing we will be asked if different types of drives are detected is which of these types the user wishes to mount. This is done with the function =asktype= which is declared below.
|

#+BEGIN_SRC fish

function asktype

#+END_SRC

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

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.

case "USB"
|

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

#+BEGIN_SRC fish

If nothing is selected, the function will naturally exit. Now, let’s close our switch statement and our function.

=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.

To correctly get the password from ~pass~, we need to parse the output and only get the first line, hence the following command.
