[Org, Emacs] Do not add spaces in front of code in src blocks 
By default, org-mode will add two spaces before code lines in the org
file itself. This does not change how code is edited when editing a
code block through `org-edit-special' but when copy/pasting code or
editing it directly from the org file, it can be troublesome.
Setting `org-src-preserve-indentation' to `t' prevents org from adding
these two spaces.

* Introduction
:PROPERTIES:
:CUSTOM_ID: Introduction-5942aea3
:END:
[[https://github.com/dylanaraps/neofetch][Neofetch]] is a CLI utility used to display system information. It was written in
Bash, and thus its configuration file is written as a Bash script too. This
document was written with org-mode, and my configuration file is tangled from
the source blocks you will see below to ~~/.config/neofetch/config.conf~. This
configuration will only contain what I need. For any further information, please
refer to the [[https://github.com/dylanaraps/neofetch][original repository]] and [[https://github.com/dylanaraps/neofetch/wiki/Customizing-Info][its documentation]].
* The ~print_info~ functions
:PROPERTIES:
:CUSTOM_ID: The_print_info_functions-bb30763f
:END:
The ~print_info~ function is the function called by Neofetch in order to print
the system information it could fetch. In this function, we’ll choose what to
display, and how. This function looks like this:
#+BEGIN_SRC sh :tangle no
print_info() {
# Print information here…
}
#+END_SRC
Generally, what we will display will be shown through the ~info~ function,
redefined inside Neofetch (this is not ~info(1)~). This ~info~ function accepts
one or two arguments. With one argument, such as with ~info memory~, we can get
a result that looks like ~5136MiB / 15873MiB~, while calling it with two
arguments will treat the first one as a prefix and the second one as the
interesting information; ~info "Memory" memory~ will look like
~Memory: 5136MiB / 15873MiB~. Here is what we want to display:
#+NAME: info-elements-table
| Prefix | Information | What it does |
|----------+-------------+------------------------------|
| | title | Username and hostname |
| | line_break | Insert a blank line |
| | cols | System theme |
| | line_break | Insert a blank line |
| Distro | distro | Distribution name |
| Kernel | kernel | Kernel version |
| Uptime | uptime | Machine uptime |
| Packages | packages | Number of installed packages |
| Shell | shell | User’s default shell |
| WM | wm | User’s Window Manager |
| Terminal | term | Default terminal |
| CPU | cpu | CPU information |
| GPU | gpu | GPU information |
| Memory | memory | RAM information |
#+NAME: info-elements-gen
#+BEGIN_SRC emacs-lisp :var table=info-elements-table :cache yes
(mapconcat (lambda (x)
(let ((prefix (car x))
(information (cadr x)))
(format "info %s%s"
(if (not (string= prefix ""))
(format "\"%s\" " prefix)
"")
information)))
table
"\n")
#+END_SRC
#+RESULTS[83eb4aaa554df955ad996157d911eec3a9251628]: info-elements-gen
#+begin_example
info title
info line_break
info cols
info line_break
info "Distro" distro
info "Kernel" kernel
info "Uptime" uptime
info "Packages" packages
info "Shell" shell
info "WM" wm
info "Terminal" term
info "CPU" cpu
info "GPU" gpu
info "Memory" memory
#+end_example
Hence, the function looks like so:
#+BEGIN_SRC sh
print_info() {
<<info-elements-gen()>>
}
#+END_SRC
Each of these modules can be tuned with the variables presented below.
* Information settings
:PROPERTIES:
:CUSTOM_ID: Information_settings-9d4cfe88
:END:
Each of the following variable tunes a function that can be called in
~print_info~ described above. It is possible to tune them by modifying this
document or the configuration file itself, and they can be overridden by the
command line with flags passed to ~neofetch~. I will divide these variables in
two main categories: hardware and software-related properties.
** Software
:PROPERTIES:
:CUSTOM_ID: Information_settings-Software-59f4cb0f
:END:
*** OS
:PROPERTIES:
:CUSTOM_ID: Information_settings-Software-OS-67908fc4
:END:
**** Distro
:PROPERTIES:
:CUSTOM_ID: Information_settings-Software-OS-Distro-cd12bc4f
:END:
This variable can shorten the output of the ~distro~ function.
- Default value :: ~"on"~
- Values ::
- ~"on"~
- ~"off"~
- Flag :: ~--distro_shorthand~
- Supports :: Everything except Windows and Haiku
- Examples ::
- on :: ~Arch Linux~
- off :: ~Arch~
#+begin_src sh
distro_shorthand="off"
#+end_src
It is possible to display when the distro has been installed on the computer.
***** Distro art or image
:PROPERTIES:
:CUSTOM_ID: Information-settings-Software-OS-Distro-Distro-art-or-image-e60cbd1e
:END:
By default, Neofetch will display ascii art next to our system information
representing our distro’s logo. We’ll customize it a bit. First, let’s change
the ~backend~ value. Note that most of them (except ~off~ of course) support
shorthands such as ~--kitty~ when passed as arguments from the command line. In
my case, I will use the Kitty backend since it is the native backend of the
terminal emulator I use.
- Default value :: ~"ascii"~
- Values ::
- ~ascii~
- ~caca~
- ~catimg~
- ~chafa~
- ~jp2a~
- ~iterm2~
- ~off~
- ~pot~
- ~termpix~
- ~pixterm~
- ~tycat~
- ~w3m~
- ~kitty~
- ~ueberzug~
- ~viu~
- flag :: ~--backend~
#+BEGIN_SRC sh
image_backend="kitty"
#+END_SRC
Now, since I indicated I wanted an image engine, I’ll indicate neofetch which
image to find. Note that ~auto~ will pick the best image source for whatever
image backend is used. In ascii mode, distro ascii art will be used and in an
image mode, your wallpaper will be used.
- Default value :: ~auto~
- Values ::
- ~auto~
- ~ascii~
- ~wallpaper~
- ~/path/to/img~
- ~/path/to/ascii~
- ~/path/to/dir/~
- ~command output (neofetch --ascii "$(fortune | cowsay -W 30)")~
- Flag :: ~--source~
#+BEGIN_SRC sh
image_source="$HOME/org/config/img/leon.png"
#+END_SRC
The default image size will probably not be correct since it is half the
terminal width and I have an ultrawide monitor, so I’ll need to set it manually.
- Default value :: ~auto~
- Values ::
- ~auto~
- ~00px~
- ~00%~
- ~none~
- Flag :: ~--image-size~ or ~--size~
#+BEGIN_SRC sh
image_size="224px"
#+END_SRC

:PROPERTIES:
