rust-hyprland-json

A hyprland event json serializer, currently no multi-monitor support. Most serilization is done manual with println! fromating, and a little deserilization with serde. It is designed to be used with a json parsers like jaq or jq and jaq in eww.

Features

• Workspace id's and names and their windows data
• active window name and id
• active workspace
• All in serialized json
• Specifcy IPC socket path with --path or -p

Installation

Currently NOT packaged :(

Binary Release

Just download the pre-compiled binary under releases

Cargo Compilation

To compile with Cargo you need git (or some tool to fetch files from this repo) and cargo installed

Clone the repo

git clone https://github.com/Pogwat/rust-hyprland-json

Move into cloned repo folder

cd rust-hyprland-json

Compile the code in src

cargo build --release

The binary should be stored in:
./target/release/rust-hyprland-json

Using Nix (my preferd way)

You obviously need to have nix installed This for for Nixos specifically but can be adapted for nix:

Save this to a file.nix replace file.nix with a name

{ rustPlatform, lib, fetchFromGitHub }:
rustPlatform.buildRustPackage rec {
  pname = "rust-hyprland-json";
  version = "0.4";
  src =  fetchFromGitHub {
    owner = "Pogwat";
    repo = "rust-hyprland-json";
    rev = "v${version}";
    hash = "sha256-zKj9nAeIaba/PDA/vkWXTzbkwBI1GSuzQtKW5DYkJTc=";
  };
  cargoLock = {
    lockFile = "${src}/Cargo.lock"; 
  };

  meta = {
    description = "Read hyprland events from hyprlands socket and output them into serlieaized json ";
    homepage = "https://github.com/Pogwat/rust-hyprland-json/";
    license = lib.licenses.gpl3Only;
    platforms = lib.platforms.linux;
    maintainers = with lib.maintainers; [];
    mainProgram = "rust-hyprland-json";
  };
}

Add this to configuration.nix Repalce /path/to/file.nix.nix with the actual path of the above file

nixpkgs.overlays = [

(final: prev: {
  rust-hyprland-json = final.callPackage /path/to/file.nix.nix {};
}) 



];

environment.systemPackages = [rust-hyprland-json];

Usage

~~Currnetly NO command line arguments.~~Now with command line arguments. -p,--path for custom IPC path -h, --help for help -v, --version for version

run rust-hyprland-json and pass it to a json parser

Eww

My personal eww config uses it for the status bar Heres a snippet:

(deflisten all
'rust-hyprland-json')

(defwidget window []
  (box  :orientation "h" :space-evenly true :halign "end"
    (label  :text  '${all.active_window}' )
    ))

(defwidget sidestuff []
  (box  :orientation "h" :spacing 20 :space-evenly false  :halign "end"
    (label  :text "${round(EWW_RAM.used_mem/(powi(1024, 2)),0)}MB" )
    (label  :text  time )
    (label  :text date )
   ; (label  :text   {EWW_BATTERY.BAT0.status} )
    (label  :text   "${round(EWW_CPU.avg, 2)}%" )
    (label  :text "${bluetooth_name}: ${bluetooth_battery}% ")

)
  )


(defwidget workspaces[]
(box
       :orientation "h"
       :space-evenly true
       :halign "start"

 (for workspace in {all.workspaces}
  (button 
  :onclick `hyprctl dispatch workspace "${workspace.name}"`
  :class {workspace.id == all.active_workspace ? 'active' : ''}
 
   `${workspace.name}`))))

   (defwidget bar []
  (centerbox :orientation "h"
    (workspaces)
    (window)
    (sidestuff)))
