Important Notes

• This tool is a side project and is provided as is, without guarantee of long term maintenance. If this is fine for you, you can proceed. Enjoy!
• This tool is usable at this point, but is still in early development! Your work is subject to bugs, backup your saves!
• I have limited time and energy, and this is not my sole project. Do not expect regular and/or crazy activity!

Hacking

• NodeJS must be installed (It will install npm too).
• Rust must be installed: https://www.rust-lang.org/tools/install
• Clone the git repository (you can also use GitHub's download button if you only want to perform tests).
• Install node modules and dependencies using npm ci.
• Husky hooks are set up automatically when you run npm ci or npm install (no need to run husky init manually).
• Open the repository folder in a prompt and run npm run tauri:dev. On a first run, all Rust crates will be compiled as well as the Svelte front. It may take some time.
• FFmpeg: To be defined once integrated.

Creating builds

To be defined once Tauri builds are configured.

Where is the CLI?

There is no CLI support for now, however this is not excluded considering that Tauri supports it. It is not prioritized right now.

Dev troubleshooting

svelte component has no default export

Restart the Svelte language server in VS Code (Command Palette → "Svelte: Restart Language Server")
