hyprland/workspaces: clarification on window-rewrite precedence

[MartinLoeper]

I configured the following rules for the hyprland workspaces module.
I want some rules like the Chrome one to have precedence but currently the neovim rules always take precedence.
Could someone please explain why and how to structure these properly?

"window-rewrite" = {
  # note: these fuzzy rules should have least priority
  "title<.*nvim.*>" = "";
  "title<.*(- n ).*>" = "";
  "title<(.*[$%#] *)?([hb]|nv)top.*>" = "";
  "title<.*Zellij.*>" = "";
  "title<Signal>" = "󰍡";
  "title<WhatsApp.*>" = "";
  "title<.[0-9]+. WhatsApp.*>" = "°";
  "title<(.* - )?(.[0-9]+. )?YouTube.*>" = "";
  "title<.* - Gmail .*>" = "󰊫";
  "title<Winetricks.*>" = "󰡶";
  
  "class<Pcmanfm>" = "";
  "class<com.github.weclaw1.ImageRoll|nomacs>" = "";
  "class<firefox>" = "";
  "class<obsidian>" = "󱞁";
  "class<ONLYOFFICE Desktop Editors>" = "󰈙";
  "class<calibre-.*>" = "";
  "class<org.qbittorrent.qBittorrent>" = "";
  "class<org.kde.kdeconnect.*>" = "";
  "class<mpv>" = "";
  "class<vlc>" = "󰕼";
  "class<Gimp-.*>" = "";
  "class<steam.*>" = "󰓓";
  "class<steam> title<Friends List>" = "";
  "class<steam_app_[0-9]+>" = "󰮂";
  "class<lutris>" = "🦦";
  "class<Spotify>" = "";
  "class<jetbrains-idea(-ce)?>" = "";
  "class<Code>" = "󰨞";
  "class<code-insiders>" = "󰨞";
  "class<com.obsproject.Studio|zoom>" = "";
  "class<io.github.whoozle.android-file-transfer>" = "";
  "class<teams-for-linux>" = "󰊻";
  "class<discord>" = "";
  "class<legcord>" = "";
  "class<MongoDB Compass>" = "";
  "class<org.keepassxc.KeePassXC>" = "";
  "class<mingo>" = "";
  "class<thunderbird>" = "";
  "class<org.wezfurlong.wezterm>" = "";
  "class<com.mitchellh.ghostty>" = "";
  "class<Postman>" = "";
  "class<(Chromium)|(Chrome)>" = "";
};

Quick Explanation

The rewrite rules are as far as i know just rules to add icons for specific applications next to your workspace numbers. Those icons get assigned to the applications based on one of 4 rules:

Config Naming	Categry
something	Vague
class<something>	Class-only
title<something>	Title only
class<something> title<something2>	Hybrid

Idea of what might work

They are not read in any specific order of how they appear in the config but from top to bottom within your "window-rewrite"={ ... };

Line 1: "title<.*nvim.*>" = "";
Line 43: "class<(Chromium)|(Chrome)>" = "";

You could try exchanging the block of applications searched for by their class<> with the ones searched for by title<>.

What could help understanding your issue better

• xprop to find out WM_CLASS (string) of both the apps you want to have preceding eachother.
• your entire config or config.jsonc whereever you add the entire module configuration.
• what steps of resorting the icons you have tried and whether your changes generally made an effect on their sorting

Wiki i found that could help:
Workspace Configuration
Waybar Hyprland Window

Hope this helps! If you have any questions or need further help, feel free to ask :)
