New run script: selectable preset at launch

[peterng1618]

Added a new run script + batch file:

• Scan & list all available presets, allowing users to select a preset at launch, eliminating the need to make a new batch file for every new preset.
• Error handling for invalid inputs.
• Handling when no presets folder/files are found: launch without preset.

I recognize there are probably more elegant implementations to achieve this goal. This implementation is intended to be non-disruptive to the users who prefer the existing run files. Feel free to refactor as you see fit.

Unfortunately this was an already rejected proposal since two months ago or so

In fact, what we really need is to switch presets within the webui.

the config dict can easily be updated after startup by using

Fooocus/modules/config.py

Lines 84 to 95 in 7b5bced

	if isinstance(preset, str):
	preset_path = os.path.abspath(f'./presets/{preset}.json')
	try:
	if os.path.exists(preset_path):
	with open(preset_path, "r", encoding="utf-8") as json_file:
	config_dict.update(json.load(json_file))
	print(f'Loaded preset: {preset_path}')
	else:
	raise FileNotFoundError
	except Exception as e:
	print(f'Load preset [{preset_path}] failed')
	print(e)

, but previously used config values have to also be changed everywhere again, which results in every element using a value of the config also having to be re-rendered (reloading the website might be sufficient though).
=> IMHO it's currently easier to just restart the whole application, but the request is understandable.

How do you envision a potential preset change function in the UI to work?

I've implemented a UI-based solution, which still keeps the preset set in args as default.
You can find it here: #1570

It would be great if you could provide feedback so we can achieve a common goal :)

Hi

I just created a fork fooocus project version just synced with the original project in main branch
https://github.com/MindOfMatter/Fooocus-MindOfMatter-Edition

I created a pr in my fork project to show what we need to change to enable the feature

MindOfMatter/Fooocus-MindOfMatter-Edition#6

If you want to test it, you need to replace your fooocus local folder with mine
(according to selected feature branch)

Also my dev branch contains all merged tested pr features in my fork project
https://github.com/MindOfMatter/Fooocus-MindOfMatter-Edition/tree/dev

I hope that it could help you :)

Have a nice day
