rlbuddy doesn’t use the default eframe persistence feature for savedata anymore, which is pretty cool. There were a few reasons for this:

1. It was kind of unnecessary, since eframe uses ron and it was storing a bunch of extra widget data which didn’t really fit with the app model anyway
2. It took up extra dependencies (removing the feature shaved off like 10)
3. There’s a bug where if the app crashed, it would erase all savedata, which, as you can imagine, was quite annoying especially since I actually use the app along with developing it, meaning if the app crashed in development it would delete all my actual match data.
4. It’s easier to externally modify, so if in development I want to mess with some values it’s a lot easier.

Anyways, actually getting the data directory was pretty interesting. I’ve basically decided to only support Windows, since the music player relies on Windows APIs anyways and I don’t think the Stats API even works on Linux.

Initially, I checked out the source code for the dirs and directories crates, which led me to the dirs-sys crate (which actually isn’t even on crates.io). It used unsafe raw Win32 SHGetKnownFolderPath with the Roaming folder guid. However, since I was already using the windows-rs crate, I tried to find the WinRT equivalent. I ended up enabling the Storage_Search feature to use the API which would let me get it. Of course, this also didn’t work, because of something to do with how Windows apps are supposed to be registered.

So, I ended up just grabbing the APPDATA environment variable and using that, then joining rlbuddy\data.json to it. It’s pretty underwhelming, but it more than gets the job done. Now, whenever the app panics, I won’t lose all of my settings anymore! Pretty nice.

Anyways, that’s what mainly got accomplished. I also tried to set up a GitHub Action to build it and make a release, but I kept hitting errors so I gave up and decided to upload a release next time I get the urge to actually update the GitHub repository.

There’s also a few fixes, like the window title which has actually had a typo since refactors from around a month ago, and adding a missing ! which broke toasts when in training.

Overall, only an hour or so was tracked, but a heck of a lot got done. See you all next time!
