This commit adds PumoPM back to the autostart script. Its transition to a systemd unit isn’t complete yet. `sshbind' has been added as a shorthand for an `ssh' command. Since I do not use polybar anymore, `polybar-launch' has been deprecated.

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.

Because I sometimes switch from window manager to window manager, creating a

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. ~set-screens~ is a custom script declared [[*set-screens][below]].

: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.

Askpass is a simple script that invokes ~rofi~ as a way to get from a GUI the

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

: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

- 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

: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

Now, let’s create a git repository and initialize it.

#+BEGIN_SRC fish
|
||
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

emoji is selected, it is copied to the clipboard using =xclipboard=.

#+BEGIN_SRC fish

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

#+BEGIN_SRC fish

: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.

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

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
|

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

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?")

end
|

: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

sudo -A mount $chosen $mp && \

#+BEGIN_SRC fish
|

case "USB"
|

mountusb

switch (wc -l < $TMPDRIVES)

Now, let’s set the ~DETECTEDSCREEN~ variable with a simple ~grep~. If the

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

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
