# hyprfreeze
Hyprfreeze is a utility to suspend a game process (and other programs) in Hyprland.

https://github.com/Zerodya/hyprfreeze/assets/73220426/541318e2-441a-485a-91c5-f58d4f65926a

**Useful to:**
- Pause single-player games that can't normally be paused (Elden Ring, Baldur's Gate 3, ...)
- Pause cutscenes to read the subtitles or if you suddenly need to leave your desk
- Save system resources (excluding RAM) if you need them for another computer task, or if the game's pause menu uses too many

**Note:** Running games in [**gamescope**](https://github.com/ValveSoftware/gamescope) is highly recommended. (See [#1](https://github.com/Zerodya/hyprfreeze/issues/1))

## Installation
### Arch Linux
Hyprfreeze is available in [AUR](https://aur.archlinux.org/packages/hyprfreeze-git).

### Dependencies
- `hyprland` to get the pid of the active window with hyprctl
- `jq` to parse json
- `psmisc` contains 'pstree' which is required to list child processes
  ### Optional
- [`hyprprop`](https://github.com/vilari-mickopf/hyprprop) to get the pid of a window by selecting it with your mouse
  ### Highly Recommended
- [`gamescope`](https://github.com/ValveSoftware/gamescope) fixes mouse input not working in other XWayland windows after pausing a Wine game. It's also the superior way to game in Wayland anyway.

### Manual
Clone this repo and symlink the `hyprfreeze` script to a directory in your `PATH`:
```bash
$ git clone https://github.com/Zerodya/hyprfreeze.git Hyprfreeze
$ ln -s $(pwd)/Hyprfreeze/hyprfreeze $HOME/.local/bin
$ chmod +x Hyprfreeze/hyprfreeze
```

## Usage
Add a bind in your Hyprland config to pause the current active window:
```
# ~/.config/hypr/hyprland.conf

...

# Toggle freeze on active window
bind = , PAUSE, exec, hyprfreeze -a
```
### Available flags
```
-h, --help            show help message

-a, --active          toggle suspend by active window
-p, --pid             toggle suspend by process id
-n, --name            toggle suspend by process name/command
-r, --prop            toggle suspend by clicking on window (hyprprop must be installed)

-s, --silent          don't send notification
-t, --notif-timeout   notification timeout in milliseconds (default 5000)
--info                show information about the process
--dry-run             doesn't actually suspend/resume a process, useful with --info
--debug               enable debug mode
```
### Examples:
```
# Pause game by process name
hyprfreeze -n eldenring.exe
```
```
# Get info about a process by clicking on its window, without suspending it
hyprfreeze -r --info --dry-run
```
## Disclaimer
There is always the risk, although slim, that an application may crash.

This is intrinsically related to modifying running processes and is not something that Hyprfreeze can prevent.
