Add linux port

[jthistle]

So, I sort of went and ported this to Linux... it seems to work pretty well.

The one thing that doesn't work is the 'commands' route on the web server - I'm not sure what that's meant to do, maybe you could give some advice @Koenvh1 ? :)

This is based on v3.1.0, but I have to PR into a branch rather than a tag, so master it is then. It may work with master, I haven't tested it.

Work-in-progress.

The "official" server window has a couple of options, e.g. it detects which game is running (ETS2 or ATS), determines the language (en-GB, nl-NL, he-IL, etc.), and supports global keyboard/controller bindings for e.g. changing the volume and station. To pass these settings to the browser, the browser polls the server for "commands"* and checks for differences (this is what the id is for, can be as simple as a timestamp of change or hash of the object). If there is a difference, it executes the action, changes the language, and switches between ATS and ETS2 (if there is a difference).

* Originally it just passed the keyboard presses to control the playback, thus the name commands

That's what the commands object looks like.

What the action and amount look like is something you can find in the function named writeFile (I believe because it used to write an actual JSON file to disk) here
https://github.com/Koenvh1/ets2-local-radio/blob/master/server/ETS2%20Local%20Radio%20desktop/Main.cs#L516

Just search for writeFile in that class, and you can see what it is called with.

[jthistle]

That's great, thanks for the help.

[jthistle]

So, this is pretty much working minus the feature to use commands, allthough it feeds the commands route the data it expects to prevent errors. I do need to write some more docs for it though, and probably add some better installation / setup scripts.

Up to you @Koenvh1 whether you want to merge this or not once that's done, do let me know what you think :)

[Koenvh1]

I will test it (and so will a couple of other people who I know have asked for a Linux version before), and if it works, then I don't see why not. The only thing I am not sure about are the JavaScript additions, but that's something I would have to look into.

[jthistle]

Sure, I can remove that if you want. I just wanted to see if I could make it so that when I turned the engine off, the radio would also stop (immersion!)

Rest of that sounds good, thanks for feedback on this :)

[Koenvh1]

Are you sure that your read_line keeps working? Someone had issues where it would work initially, but break after some time (and no longer switched stations when crossing a border)

[jthistle]

That's possible. I may need to add something to catch if the read_util dies or the pipe breaks, and to restart it if that happens.

[jthistle]

@Koenvh1 I've made some improvements to how errors are handled. Let me know if that helps.

[Remyrios]

Okay so I'm the mystical person that has asked for a linux version before. Pulled the latest commit and the one main issue still persists. The stations don't automatically switch when crossing a border nor do they start playing when you first open up the app/website. Also after the commit it's screaming at me with this error:

@Kaperios I see, thanks for testing it out. I think I know how to fix that one, and I'll look into the border crossing thing - I imagine I need to send the correct command. I'll ping you again once I've tried to sort it.

[jthistle]

@Kaperios what is the expected behaviour when first opening the website? Which station do you expect to start playing automatically? I'm asking because I can't test this in Windows. Thanks.

[jthistle]

@Kaperios @Koenvh1 Hi, I think I've fixed it now. Please give it a go and let me know if it works!

[Lezurex]

I recently found out about this ETS2 plugin, unfortunately, there was no official Linux release. I found this PR here, pulled the latest commit, built it and tried it out for a couple of hours. It works really well. Had no problems so far.

I'd love to see this as an official release soon!

[jthistle]

Good to hear - unfortunately comms went dark after my last comment in this PR. I too would like to see this merged if possible :)

[Koenvh1]

The thing is that I do not have a computer to test it on currently, hence I asked @Kaperios to test it for me. If he experiences issues, then probably something needs fixing.

[jthistle]

@Koenvh1 I understand, it's just that after the issues were reported I fixed them and said so, but I didn't recieve any further communication after that.

[Koenvh1]

I have added a link to here on the releases page. Just as a heads-up, I am planning a version 4 which will lead to some breaking changes.

[Koenvh1]

I released the beta version of 3.3, which serves a lot of files locally again due to some policy changes with Google Chrome. I would recommend checking whether your Linux version supports that as well, otherwise it will stop working with starting from Chrome 93 (due to be released on 31 August).

[jthistle]

I made only one insignificant change to the web part of the code, so it should be fine, I would think.
