This file will present all the executable scripts I wrote. It is also their
original source code, all the following code snippets are exported and tangled
from this file to the actual executables.
Please do not forget to run the following before tangling files from this file
to make sure the tangled files will be executables.

Usage: =4chandl [ URL TO THREAD ]=
I made this small script to download the attached files of 4chan threads.
First of all, lets declare it as a fish script.
#+BEGIN_SRC fish
#!/usr/bin/env fish
#+END_SRC
Now, lets check if any arguments were passed to the executable. If none were
passed, the script should be aborted.
#+BEGIN_SRC fish
if ! count $argv > /dev/null
echo 'No URL specified! Give the URL to thread as the only argument.'
exit 1
end
#+END_SRC
Now, lets store the regex we use to get the link to the attached files.
#+BEGIN_SRC fish
set regex_4cdn '\/\/is2\.4chan\.org\/[a-z]+\/[A-Za-z0-9]+\.[A-Za-z]{3,4}'
#+END_SRC
Well use a thread counter to get a visual indication on how the download is
going.
#+BEGIN_SRC fish
set thread_counter 1
#+END_SRC
Now, we will use each of the arguments passed as a URL to download the files
from.
#+BEGIN_SRC fish
for url in $argv
#+END_SRC
As a visual indicator, lets get the amount of elements we are going to
download from the current thread and print it.
#+BEGIN_SRC fish
set file_total (curl -ks $url | grep -oE $regex_4cdn | uniq | wc -l)
echo total files to download in current thread: $file_total
#+END_SRC
Lets set a file counter so we can visualize the download progress.
#+BEGIN_SRC fish
set file_counter 1
#+END_SRC
Now, lets download each file from the current thread.
#+BEGIN_SRC fish
for image_url in (curl -k -s $url | grep -Eo $regex_4cdn | uniq | sed 's/^/https:/')
echo -n Downloading image $counter of $total...
wget --no-check-certificate -q -nc $image_url
echo ' Done (thread: $thread_counter/thread_total\tfile: $file_counter/file_total)'
set file_counter (math $file_counter + 1)
end
#+END_SRC
Lets increment the thread counter.
#+BEGIN_SRC fish
set thread_counter (math $thread_counter + 1)
#+END_SRC
Lets now close the for loop.

: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
#!/usr/bin/env fish
set WLOCATION /usr/share/doc/arch-wiki/html/en/

rofi -dmenu -p "Arch Wiki" -i | sed '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~.

Askpass is a simple script that invokes ~rofi~ as a way to get from a GUI the
users 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]]. As you can see, this is a oneliner if
we ignore the initial shebang. This executable is pointed at by the

~backup~ is a very simple, oneliner script that will create a local copy of a
2019-10-24 21:10:01 +00:00
file and add the date at which it was copied in the filename. You can see its
source code here:

:END:
~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. Well use the ~nmcli c s~ command to get the list of the
available networks, and well chose one with ~rofi~.
#+BEGIN_SRC fish

egrep -o '([0-9A-F]{2}:){5}[0-9A-F]{2}\s*(.*)Infra' | \
egrep -o '\s+(.*)\s+' | awk '{$1=$1}1' | \
rofi -dmenu -p "Select your WiFi network")
#+END_SRC
Now, if a network was selected, lets attempt to connect to it. Otherwise,
lets just send a notification no network was selected.
#+BEGIN_SRC fish

=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=.
#+begin_src fish
#!/usr/bin/env fish
#+end_src
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, lets set a couple of variables which will prove useful later on when
trying to set up our project.

:END:
=cnew= is a small utility script similar to but simpler than cppnew that
2019-10-24 21:10:01 +00:00
creates a CMake template C project from the template that already exists in
[[file:~/dev/templateC][~/dev/templateC]]. This script is a fish script, so lets insert the shebang.
#+BEGIN_SRC fish
#!/usr/bin/env fish
#+END_SRC
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
Lets close the switch statement.
#+BEGIN_SRC fish
end
#+END_SRC
Now, lets 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 $argv[1]
#+END_SRC
The default files have a placeholder for the name of the project. Lets
replace these placeholders with the projects name.
#+BEGIN_SRC fish
sed -i "s/PROJECTNAME/$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, lets create a git repository and initialize it.
#+BEGIN_SRC fish
git init
git add .
git commit -m "initial commit"
#+END_SRC
And were done!

: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/env fish

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=.
#+BEGIN_SRC fish
#!/usr/bin/env fish
grep -v "#" ~/.config/emoji.txt | rofi -dmenu -p "Select emoji" -i | \
awk '{print $1}' | tr -d '\n' | xclip -selection clipboard

Also, lets send a notification telling the user the emoji has been copied!
#+BEGIN_SRC fish
set emoji (xclip -o -selection clipboard | tr -d '\n')
test -z "$emoji" && notify-send "No emoji copied" -u low && exit
set -a emoji "copied to clipboard"
notify-send -u low $emoji

Now, lets 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. Well 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, well 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?")

Alright, we want to mount a partition that answers by the name of
=/dev/sdXX=, how do we do that? Lets 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 lets pipe them into
rofi so we can chose from it. Also, =awk= will get their path in =/dev=.
#+BEGIN_SRC fish
2019-10-23 10:00:28 +00:00
set -g chosen (echo $usbdrives | \
rofi -dmenu -i -p "Mount which drive?" | \
awk '{print $1}')
#+END_SRC
As usual after a user selection, lets verify something has actually been
selected. If not, lets abort the script.
#+BEGIN_SRC fish
test -z $chosen && return 1
#+END_SRC
2019-10-23 10:00:28 +00:00
Now, lets select the mount point of our partition. Well call the function
=getmount= described in [[#Rofi-mount-Get_the_mount_point-6c4bac06][Get the mount point]] to select it.
2019-10-23 10:00:28 +00:00
#+BEGIN_SRC fish
getmount
#+END_SRC
Lets 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, lets mount it! Well 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, well let =mount= determine which filesystem is used by the partition
(generally =ext4=).
#+BEGIN_SRC fish
case '*'
sudo -A mount $chosen $mp
#+END_SRC
Well 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) $mp
#+END_SRC
Lets close the switch block and send a notification the partition has been
mounted.
#+BEGIN_SRC fish
end && notify-send -a "dmount" "💻 USB mounting" "$chosen mounted to $mp."
#+END_SRC

Lets declare it.
#+BEGIN_SRC fish
function mountandroid -d "Mount an Android device"
#+END_SRC
Well 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 $chosen | sed 's/,.*//')
#+END_SRC
Lets temporarily mount our device.
#+BEGIN_SRC fish
jmtpfs -device=$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. Lets 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, lets get the actual path of our Android filesystem we wish to mount,
and lets 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."

This part is way easier than the previous functions. As we will see, the
function =mountcd='s body is only three lines long. First, lets declare the
function.
#+BEGIN_SRC fish

Now, lets chose the CD drive we want to mount using =rofi=.
#+BEGIN_SRC fish
set chosen (echo $cddrives | rofi -dmenu -i -p "Which CD drive?")
#+END_SRC
Well also get the mountpoint thanks to the =getmount= function described
earlier.
#+BEGIN_SRC fish
getmount
#+END_SRC
And finally, lets mount it and send the notification everything went well.
#+BEGIN_SRC fish
sudo -A mount $chosen $mp && \

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.
#+BEGIN_SRC fish
switch (cat $TMPDRIVES | rofi -dmenu -i -p "Mount which drive?")
#+END_SRC
If we chose the option "USB", well mount a hard drive, partition or USB
drive. In which case well 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"
mountandroid
#+END_SRC
Else if we chose the "CD" option, well call the =mountcd= function.
#+BEGIN_SRC fish

2019-10-23 10:00:28 +00:00
is passed in a switch statement.
#+BEGIN_SRC fish
switch (wc -l < $TMPDRIVES)
#+END_SRC
If the file has no lines, i.e. it is empty, we have no mountable media. Lets
inform our user this is the case.
#+BEGIN_SRC fish
case 0
notify-send "No USB drive or Android device or CD detected" -a "dmount"
#+END_SRC
If we only have one line, we have only one type of mountable media. Well
pass this line to a second switch statement.
#+BEGIN_SRC fish
case 1
switch (cat $TMPDRIVES)
#+END_SRC
This will allow the script to automatically detect what type of media it is,
and mount the corresponding function.
#+BEGIN_SRC fish
case "USB"
mountusb
case "Android"
mountandroid
case "CD"
mountCD
#+END_SRC
Lets close this nested switch case.
#+BEGIN_SRC fish

=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. It is a fish script, so lets declare it as one.
#+BEGIN_SRC fish
#!/usr/bin/env fish
#+END_SRC
Lets 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

Now, lets get the list of the passwords that exist in our =pass= repository.
#+BEGIN_SRC fish

password was selected, lets simply exit the script.

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 lets 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.
Lets do that.

#+BEGIN_SRC fish :noweb yes :tangle no
set -l IFS
<<rofi-pass-type-get-password>>
printf %s $pass | xvkbd -file -

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

I made a small and quick utility to set up my Wacom tablet so it is only bound
to one screen. This is a fish script, so lets insert the sheband.

** Set our variables

:END:
Lets 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, lets 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. Lets 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, well 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 lets close our function.
#+BEGIN_SRC fish
end

** Select our screen

:END:
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. Lets declare our function.
#+BEGIN_SRC fish
function set_screen
#+END_SRC
First, lets 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, lets select the one we wish to use using rofi.
#+BEGIN_SRC fish
set -g SCREEN (for d in $CONNECTED_DISPLAYS
echo $d
end | rofi -dmenu -i -p "Select your dispaly" | tr -d '\n')
#+END_SRC
Now, lets get the resolution of our selected screen.
#+BEGIN_SRC fish
set -l LINE (xrandr -q --current | if [ "$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, lets 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, well have to abort the script.
#+BEGIN_SRC fish
if test -z $WIDTH || test -z $HEIGHT
exit 1
end
#+END_SRC
Lets close our function now.
#+BEGIN_SRC fish
end
#+END_SRC
** Adjust the tablet

:CUSTOM_ID: Wacom_setup-Adjust_the_tablet-342acaf3
:END:
This function will take care of adjusting our tablet to our screen. Lets
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 lets 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 tablets area is greater than the
theoretical new area, it means the current area is too high. Otherwise, it
should be the other way around. Lets 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 $RATIOAREAY
else
set -g NEWAREAX $RATIOAREAX
set -g NEWAREAY $AREAY
end
#+END_SRC
Alright, now lets set the new area with these new variables.
#+BEGIN_SRC fish
xsetwacom set "$DEVICE" Area 0 0 $NEWAREAX $NEWAREAY
xsetwacom set "$DEVICE" MapToOutput "$SCREEN"
#+END_SRC
Lets slow down the cursors speed on the touchpad.
#+BEGIN_SRC fish
xinput set-float-prop $DEVICETOUCH $WACOMPROPTOUCHSPEED 0.5
#+END_SRC
Lets also slow down the scroll speed of the touchpad.
#+BEGIN_SRC fish
xsetwacom set $DEVICETOUCH $WACOMPROPSCROLLPSEED "90"
#+END_SRC
Now, lets close the function.
#+BEGIN_SRC fish
end
#+END_SRC

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
#!/usr/bin/env fish
if count $argv > /dev/null
set -l SEARCH (string join '+' $argv)
