* 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 |
| OS | 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)
(format "info %s%s"
(if (not (string= (car x) ""))
(format "\"%s\" " (car x))
"")
(cadr x)))
table
"\n")
#+END_SRC
#+RESULTS[1e66bf48472ad24006f0cb9dc9c86078764ba84e]: info-elements-gen
#+begin_example
info line_break
info title
info line_break
info cols
info line_break
info "OS" 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
info "Disks" disks
#+end_example
Hence, the function looks like so:
#+BEGIN_SRC sh
print_info() {
<>
}
#+END_SRC
Each of these modules can be tuned with the variables presented below.
* Information settings
:PROPERTIES:
:CUSTOM_ID: Information_settings-9d4cfe88

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

command line with flags passed to ~neofetch~. I will divide these variables in
two main categories: hardware and software-related properties.
