Add decky-syncthing

decky-syncthing (Syncthing)

Plugin for managing Syncthing to synchronize files with other devices. Not officially affiliated with the Syncthing project.

From the README:

A Decky plugin to manage Syncthing from your Steam Deck.

This plugin allows you to start and stop Syncthing from the Quick Access panel of your Steam Deck.

It also has some basic stats and allows you to access the web UI. It can also be configured to automatically start Syncthing with Gamescope (the Steam Deck main UI).

The plugin works no matter if you have HTTPS enabled or not and also no matter if you have basic auth enabled.

Since the Steam Deck UI has no support for self-signed HTTPS certificates or Basic Auth, this plugin starts a proxy server on port 58384 (HTTP, localhost only) that forwards requests to the Syncthing Web UI and API.

NOTE: This PR template contained a link asking me to review https://deckbrew.xyz/en/plugin-dev/review-and-testing - this page does not exist! So I did not review that page.

• I have verified my plugin is unique or alternatively provides more/alternative functionality to a similar plugin already on the store.

Plugin Backend Checklist

• Yes: I am using a custom backend other than Python.
• Yes: I am using a tool or software from a 3rd party FOSS project that does not have it's dependencies statically linked.

Found the review and testing page at https://wiki.deckbrew.xyz/en/plugin-dev/review-and-testing - will review that now!

Reviewed the page and removed the assets directory.

Changed banner to be a PNG.

You should probably have something in the plugin that mentions that the syncthing flatpak has to be installed, as users are likely to go in with zero knowledge.

The banner image needs to be a png iirc, so if you could change then it would likely work.

Also I can see you're using the custom scrollable element, hopefully that can be replaced by scrollGroup and friends when SteamDeckHomebrew/decky-frontend-lib#90 gets merged.

We noticed that OpenSSL 1.1 was apparently not guaranteed to be installed on a Deck, so I'm switching to a statically linked TLS implementation.

[theCapypara]

I replaced the link to OpenSSL with the statically compiled rustls so it should work now. I tested it on my deck and confirmed the executable does not link against OpenSSL anymore.

Additionally I updated the README and the description in the plugin.json to clarify that the Flatpak needs to already be installed: theCapypara/steamdeck-decky-syncthing@523ec90

Sorry I took so long to get back around to this. The plugin mostly functions well (entering the API key was a little tedious). However, the actual disabling/enabling of folders doesn't seem to work, they don't do anything when clicked on.

(ignore the errors in the console, they seem unrelated)

For now that's on purpose. Eventually I'll probably make it so that clicking the folders and devices shows some details.
For now representing them as buttons seemed visually to be the nicest way of doing it, even if the buttons don't do anything.

[PartyWumpus]

Ah okay, guess it's all working fine then.
