Important
Everything in this program is text-based
and no rendering library like qt or gtk ... is used
Using any font like not monospace-based ones won't do,
since every character has its own spacing
Upfront I wanted to let you know. I am an Informatics Student at the Friedrich-Alexander University in Erlangen, Germany. I am only in my second Semester, thus you might encounter bugs (I wanted a working program first before actually handling Errors). The MIT License Rules apply and therefore I cannot be held accountable for any problems you encounter but you shall not refrain from contacting me on such a case :D
The program standards I use (that get used in my uni):-std=c11 -pedantic -Wall -Werror -D_XOPEN_SOURCE=700
This program should be memory leak proof according to valgrind (valgrind.txt)
Now to the Program itself: We could describe this as a pipeline of multiple objectives. Firstly we want to extract the the keybinds of your config file and transform them into a format to simplify the rendering process [keys.sh]. The Rendered Product gets written into a text file. At last, we open the text file with anything we want to display it with. In my case, I use the kitty terminal with a read-only vim session. Adding a bind to open/close the window (Also adding a rule to hyprland to make it floating).
Extract Keybinds -> main.c -> keybinds.txt
keybinds.sh (keybinds.txt) -> hyprland.conf
gcc -std=c11 -pedantic -Wall -Werror -D_XOPEN_SOURCE=700 -o generate_file keybind_file_generator.c
Modify the shell script to your heart's content. (Using ChatGPT simplifies this process. I used it with the addition of another person's shell script source)
The format in the end should be something like: key key [...], action, command The should be a big limit on how many keys you want to add. In my terms key is something like ctrl while action is any key that isn't special like y.
generate_file > keybinds.txt
And done!
I used a bash script that works like a toggle and opens/closes a kitty window. I've missplaced my original bash script but it should look something like this.
#!/usr/bin/env bash
# Defining a unique window name
TITLE="Keybinds Viewer"
file_path="/path/to/txt/file"
# Check if kitty is already running
if pgrep -f "kitty --title $TITLE" > /dev/null; then
pkill -f "kitty --title $TITLE"
else
kitty --title "$TITLE" --hold --override font_size=14 --geometry 800x600 sh -c "vim -R -c 'set nomodifiable' $file_path;"
fi
If you use hyprland you can declare the windowrules like this to have a similar output to my preview picture.
windowrulev2 = float,class:kitty,title:Keybinds Viewer
windowrulev2 = size 800 750,class:kitty,title:Keybinds Viewer
