hotsave

Summary

Immediately backup and restore a backup for a single file using global hotkeys.

Purpose

An example use case for me personally is saving current game save states to restore them on a key press later. This is exceptionally useful for challenging games, like the Souls series, where on death you would have to redo a time intensive and cumbersome running section to reach a boss again.

While there are already some tools out there, I decided to do this application for myself for the following reasons:

• trying out cli related Rust crates
• implementing a CI/CD process for a compiled binary as learning
• concentrate on core functionality instead of providing additional features like save management
• no GUI
• fun

Requirements

Linux

Because this tool listens on global keystrokes, the user running this application needs to be in the input group.

Installation

Build from source

You can install this cli application from this git repository using cargo

cargo install --git https://github.com/robin-thoene/hotsave

Prebuilt

To get a prebuilt binary check out the release page and download it there.

Customization

You can customize the application behavior by creating a config file located at ~/.config/hotsave/hotsave.toml with the contents (note that the values are examples):

save_file_key = "F7"
restore_file_key = "F8"

If you are unsure what the name of the key is you want to customize, start the app with the environment variable RUST_LOG=debug. Just press the desired key, the debug log will show you the KeyPress value of that key that you need to use in the config.
