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.

:END:
|

Usage: =4chandl [ URL TO THREAD ]=
|
||
|
||
I made this small script to download the attached files of 4chan threads.
|
||
Let’s 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, let’s 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
|
||
|
||
We’ll 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, let’s 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
|
||
|
||
Let’s set a file counter so we can visualize the download progress.
|
||
#+BEGIN_SRC fish
|
||
set file_counter 1
|
||
#+END_SRC
|
||
|
||
Now, let’s 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
|
||
|
||
Let’s increment the thread counter.
|
||
#+BEGIN_SRC fish
|
||
set thread_counter (math $thread_counter + 1)
|
||
#+END_SRC
|
||
|

Let’s 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

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

we ignore the initial shebang. This executable is pointed at by the

available WiFi networks. The first thing to do is to select the WiFi we want

available networks, and we’ll chose one with ~rofi~.

:END: =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.
|

Now, let’s set a couple of variables which will prove useful later on when
|

trying to set up our project.
|

|
||
* Cnew

: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

git init

||
git add .
|
||
git commit -m "initial commit"

|
||
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

The emoji picker is a simple fish script that uses rofi and

Also, let’s send a notification telling the user the emoji has been copied!

#+BEGIN_SRC fish

This scripts allows the user to kill polybar and relaunch it, or to simply
|
||
launch it if polybar isn’t launched yet. First thing to do is kill all polybar
|
||
processes.
|
||
#+BEGIN_SRC bash
|

killall -q polybar
|
||
#+END_SRC
|
||
|

Now we have to wait untill all polybar processes have been shut down.

#+BEGIN_SRC bash
|

while pgrep -u $UID -x polybar >/dev/null; do sleep 1; done
|
||
#+END_SRC
|
||
|

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.
|

#+BEGIN_SRC bash

:END: =rofimount= is a script inspired by [[https://github.com/ihebchagra/dotfiles/blob/master/.local/bin/dmount][this one]], based on dmenu, which
|
||
interactively asks the user what to mount, and where to mount it. What I did
|
||
was replace dmenu with rofi, and fix a couple of bugs I encountered in the
|
||
original script.
|

:END:

#+BEGIN_SRC fish
|
||
begin
|
||
#+END_SRC
|
||
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.
|
||
#+BEGIN_SRC fish
|
||
set -l LFS
|
||
#+END_SRC
|
||
|
||
Now, let’s detect the amount of mountable Android filesystems, and if any are
|
||
detected, let’s read them into a global variable.
|
||
#+BEGIN_SRC fish
|
||
set -l a (math (jmtpfs -l | wc -l) - 2)
|
||
test $a -ge 0 && jmtpfs -l 2> /dev/null | tail -n $a | read -zg anddrives
|
||
#+END_SRC
|
||
|
||
We’ll do the same for external and internal drives and partitions that can be
|
||
mounted here.
|
||
#+BEGIN_SRC fish
|
||
lsblk -rpo "name,type,size,mountpoint" | \
|

|
||
read -zg usbdrives
|
||
#+END_SRC
|
||
|
||
Finally, we look for any CD drive that could be mounted on our device.
|
||
#+BEGIN_SRC fish
|
||
blkid /dev/sr0 | awk '{print $1}' | sed 's/://' | read -z cddrives
|
||
#+END_SRC
|
||
|
||
And that’s the end of our first block!
|
||
#+BEGIN_SRC fish
|
||
end
|
||
#+END_SRC
|
||
|
||
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
|
||
set -g TMPDRIVES /tmp/drives
|
||
rm -f $TMPDRIVES
|
||
touch $TMPDRIVES
|
||
#+END_SRC
|
||
|
||
Now, let’s write what type of drives we can mount in this temporary file.
|
||
#+BEGIN_SRC fish
|
||
test -n "$usbdrives" && echo "USB" >> $TMPDRIVES
|
||
test -n "$cddrives" && echo "CD" >> $TMPDRIVES
|
||
test -n "$anddrives" && echo "Android" >> $TMPDRIVES
|
||
#+END_SRC
|
||
|
||
Now, we want to declare where to look for mount directories. For now, we’ll
|
||
only look in =/media=, but you can add more if you wish.
|
||
#+BEGIN_SRC fish
|
||
set -g basemount /media
|
||
#+END_SRC
|
||

** Get the mount point

||
:PROPERTIES:
|
||
:CUSTOM_ID: Rofi-mount-Get_the_mount_point-6c4bac06

||
:END:
|
||
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?")
|

Finally, let’s close the function

: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.
|

#+BEGIN_SRC fish

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.

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.

function.
|
||
#+BEGIN_SRC fish
|
||
function mountcd

#+END_SRC
|

|

Now, let’s chose the CD drive we want to mount using =rofi=.

#+BEGIN_SRC fish
|

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

earlier.
|

#+BEGIN_SRC fish
|

getmount

case "USB"
|

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

set internal "eDP1"

|

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

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,

|
||
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 detect the current status of the touchpad:
|
||
#+BEGIN_SRC fish
|
||
set TPSTATUS (xinput list-props 12 | 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
|
||
|
||
Now 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
|

|

Finally, let’s update the touchpad’s options:
|

#+BEGIN_SRC fish
|

xinput set-prop $TPNAME "libinput Tapping Enabled" $NEWTPSTATUS

If our screen is too high or too wide for our tablet, we will have to adjust

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

||
sequencially.
|
||
#+BEGIN_SRC fish
|
||
set_device
|
||
set_screen
|
||
adjust_device
|
||
#+END_SRC
|
||
|
||
* Weather
|
||
:PROPERTIES:
|
||
:HEADER-ARGS: :shebang "#!/usr/bin/env fish" :mkdirp yes :tangle ~/.local/bin/we
|
||
:CUSTOM_ID: Weather-4ed00bb0
|
||
:END:
|
||
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 '+' $argv)
|
||
curl http://v2.wttr.in/~$SEARCH
|
||
else
|
||
curl http://v2.wttr.in/Aubervilliers
|
||
end
|
||
#+END_SRC
