[EPIC] Snap and Flatpak compatibility

[QbDesu]

The BetterDiscord installer doesn't support Flatpak or Snap. The first Linux distros start seemlessly integrating these types of packages in their software store and as their main method of installation.

Well, to be fair saying that the installer doesn't support snap isn't quite right either. Rather it explicitly blocks installing to snap even though it would otherwise be supported.

Installer/src/renderer/actions/paths.js

Lines 84 to 87 in 1bf733d

	if (proposedPath.includes("/snap/")) {
	remote.dialog.showErrorBox("BetterDiscord Incompatible", "BetterDiscord is currently incompatible with Snap installs of Discord. Support for snap installs is coming soon!");
	return "";
	}

Flatpak on the other hand actually needs some more work because of it's sandboxing by the looks of it. More specifically it can't read the betterdiscord.asar from user's config directory, so it needs to be installed in the flatpak's config directory.

The snap installation has a related problem. because it's betterdiscord.asar is in the user config directory while the detected config directory is in the snap package's directory the autoupdate functionality of BD is expected to fail.

From a chat with @Tropix126 I could gather that it wasn't always compatible but changing it to injection method to inject the require statement in the discord_desktop_core/index.js module seems to have made it otherwise compatible. In fact betterdiscordctl's installation method is identical to the installer. The only relevant change for BD installation is changing the config directory detection depending on the detected.

betterdiscordctl's installation steps for comparison (warning: identical to the installer)

1. Detect config directory
2. Detect Discord folder in the config directory
3. Detect version folder in the Discord config directory
4. Detect the core module folder in the version directory
5. download betterdiscord.asar from github releases (it looks like it may also be caching the asar though)
6. create a betterdiscord and betterdiscord/data folder if they don't exist
7. copy the asar in there
8. inject require statement in index.js of the core module (only difference I can see is a newline more after the injection using betterdiscordctl)

• Techincal Requirements
  • Snap support
    • version folder detection (trivial with ProgramData version detection + Semver Version sorting #150 + @ObserverOfTime's snippet from Flatpak/snap compatibility #26)
    • remove explicit block from the path verification
    • install to betterdiscord.asar to the package's home directory
      • check if package update removes the BD config folderwhen doing so
  • Flatpak support
    • version folder detection (same as snap)
    • install to betterdiscord.asar to the package's home directory
      • check if package update removes the BD config folderwhen doing so
  • BetterDiscord compatibility?
    • BetterDiscord seems to function fine on snap and flatpak but maybe there are details that don't function correctly because they require accessing files outside of the BD config directory
• Design/UX considerations
  • should the list be exanded to include snap/flatpak?
  • should snap/flatpak be fallback if for automatic detection if the native installation is not found?
  • should snap/flatpak be in separate platform selection dialogs?
    • if so how should those be accessed?
      • keep in mind lots of people won't know what type of installation they have because the software stores of their distro's make it seemless. they probably won't even know what the hell snap/flatpak is. but would still be nice to choose which variant to install to
  • technical: adjustments to internal data structure to keep it clean
    • internal platform name + folderName + display name + image url separate, so you don't need to do .toLowercase().replace(" ","") everywhere
      • also don't hardcode the existing platforms everywhere but base them of a common object where all are defined, this would also allow adding a Discord - Snap and Discord - Flatpak platform as needed,

Snap is also sandboxed.

keep in mind lots of people won't know what type of installation they have because the software stores of their distro's make it seemless.

This is, unfortunately, true.

Fedora and Ubuntu, two of the biggest distros, according to Panic! at the Distro, now prefer installing through Flatpak and Snap respectively.

[ObserverOfTime]

Yet another reason to use Arch.

The solution is not to use Arch. This isn't an Arch vs. other distros thread. Please keep your distro supremacy out of here and make actually useful comments.

[ObserverOfTime]

The solution in Fedora is to actually use DNF instead of some dumb GUI that may use flatpak.
The solution in Ubuntu is to do yourself a favour and migrate to a decent distro.

I have just installed discord via flatpak on my arch based distro and it seems currently installing betterdiscord into the flatpak is not a trivial task and basically not supported? I tried passing the path to the discord executable or the discord directory to npm run inject, but that does not seem to be a thing I can do...
Is currently the only option to install via AUR or can I actually get betterdiscord working on the flatpak somehow?

ahh, the betterdiscord installer I guess can't handle it, but the (older?) betterdiscordctl can do it? (https://gist.github.com/ObserverOfTime/d7e60eb9aa7fe837545c8cb77cf31172)

Hey... I don't see what all the fuss is about and why this has been discussed for years, or even why anyone needs or trusts those "fancy" "betterdiscordctl" or "BetterDiscord-Installer.AppImage" tools anyway. It's literally just 1 little .asar file that needs to be placed in the Discord folder, and one little config edit. No need for all that hassle or all those bloated applications just to do such a simple little job.

 

I wrote this oneliner which automatically installs/updates BetterDiscord. It's really that easy, yes. Compare my simple line below to the huge, bloated code (example) of the other methods...

 

📓 The Code:

DISC_CONFIG="$HOME/.var/app/com.discordapp.Discord/config/discord" && BD_ASAR=betterdiscord.asar && wget --timestamping -P "${DISC_CONFIG}/../BetterDiscord/data" -- "https://github.com/BetterDiscord/BetterDiscord/releases/latest/download/${BD_ASAR}" && DISC_VER="$(ls --sort=time --time=creation "${DISC_CONFIG}" | grep -E -m 1 '^[0-9]+\.[0-9]+\.[0-9]+$')" && echo -e "require('../../../../BetterDiscord/data/${BD_ASAR}');\nmodule.exports = require('./core.asar');" | tee "${DISC_CONFIG}/${DISC_VER}/modules/discord_desktop_core/index.js" && echo -e "\nBetterDiscord installed. Restart Discord if currently running." || echo -e "\nInstallation failed."

 

😎 You can set the Discord version that you want to install into as follows:

• Edit the DISC_CONFIG variable at the start of the line, by only modifying the path that comes after HOME/.
• Discord Flatpak (Already DEFAULT in command above, NO NEED to edit anything if you're using this): .var/app/com.discordapp.Discord/config/discord
• Discord Native: .config/discord
• Discord CANARY Flatpak: .var/app/com.discordapp.DiscordCanary/config/discordcanary
• Discord CANARY Native: .config/discordcanary

 

🍓 How to use:

Just run that command, and it will do the following:

• This is only for the Flatpak and Native versions of Discord and Discord CANARY, obviously. I don't use Snap.
• Automatically downloads the latest BetterDiscord, but only if an update is available. It doesn't download anything at all if there are no updates. It does this by looking at the installed betterdiscord.asar file modification timestamp.
• Injects the betterdiscord.asar into Discord's loader script for the latest installed Discord version (version is auto-detected).
• Verifies every step of the installation process and tells you if it succeeded or if there were any issues.

That's it. Just save this command somewhere. Run it once. That's it. Run it again when you want to update BetterDiscord. You can run it as many times as you want, since it won't change anything if BetterDiscord is already installed and up-to-date.

 

⬆️ Making an easy auto-update alias:

You can even make an alias in your ~/.zshrc or ~/.bashrc if you want to easily run this command in your terminal anytime in the future:

alias betterdiscord-update="DISC_CONFIG=\"\$HOME/.var/app/com.discordapp.Discord/config/discord\" && BD_ASAR=betterdiscord.asar && wget --timestamping -P \"\${DISC_CONFIG}/../BetterDiscord/data\" -- \"https://github.com/BetterDiscord/BetterDiscord/releases/latest/download/\${BD_ASAR}\" && DISC_VER=\"\$(ls --sort=time --time=creation \"\${DISC_CONFIG}\" | grep -E -m 1 '^[0-9]+\\.[0-9]+\\.[0-9]+\$')\" && echo -e \"require('../../../../BetterDiscord/data/\${BD_ASAR}');\\nmodule.exports = require('./core.asar');\" | tee \"\${DISC_CONFIG}/\${DISC_VER}/modules/discord_desktop_core/index.js\" && echo -e \"\\nBetterDiscord installed. Restart Discord if currently running.\" || echo -e \"\\nInstallation failed.\""

(Be sure to set your personal DISC_CONFIG path here if you aren't using the default Flatpak version of Discord.)

 

⚠️ Important:

Note that GitHub presents oneliners as a very long line. Be sure to copy these correctly, or use the "copy text" button that GitHub provides.

 

🚀 Updating BetterDiscord:

As for long-term usage and updates, it's very simple too: When Discord starts up, BetterDiscord always does a version check and shows a popup screen to let you know when a new version is available.

In some situations, Discord updates will break BetterDiscord so that it doesn't load at all, and in that case you won't see any notification, but you'll easily notice that BetterDiscord isn't working anymore. In that case, simply run my command to update BetterDiscord to the latest version.

In both scenarios, it's literally brainless. You don't have to think at all. You just look at the built-in Discord notification saying that a new BetterDiscord version is available, or you notice that BetterDiscord is suddenly broken, and you do the update.

It's that easy! ⭐

 

🍌 The End 🍌

Have fun! I hope this helps someone else who just wants a simple, clean and totally safe way to install BetterDiscord for Linux Flatpaks and Native alike, while also helping you effortlessly install BD regardless of whether you use Discord or the Discord CANARY client! This is important since CANARY isn't supported by any of the other installation tools. 🏖️

In fact, if you're using the Flatpak version of Discord together with my installation method, then you will be totally protected along every step of the way, for both the installation of BetterDiscord itself (there's no malicous code in my script, which is super easy to audit), and you'll also be protected for the usage of all 3rd party plugins inside BetterDiscord itself (since they will run inside the Flatpak sandbox and won't be able to steal all your personal files). That's the installation method that I would recommend to people! 💟

@ObserverOfTime LMFAO. You're the guy who made "betterdiscordctl". I noticed that you downvoted my clean solution 30 minutes after I posted it. The amount of saltiness in you doing without a word is hilarious. I'll upvote myself just to annoy you even more. 💋

[Parent5446]

It's always amusing seeing someone so confidently proclaim, "that code is so bloated! just use this: {700 character unreadable one-liner with a quarter the functionality".

[Arcitec]

@Parent5446 You seriously mean that you work at Google yet are incapable of reading two shell commands? One wget to download BetterDiscord, and one tee to write it to Discord's loader.

And I would rather be 45 easily audited, clean words (652 characters) than the 670 awfully written, self-updating spaghetti LINES (20661 characters/2301 words) with such awful newbie practices such as hard-coding the absolute path to the BetterDiscord.asar, meaning that Discord breaks if it's moved, lmfao.

Seriously, the hard-coded path is astonishing since the default index.js literally contains a relative path already, as if to hint "hey, use a relative path, dummy". But not only is it bloated and shoddily written. You also have to trust the author never to add malware to it.

Both solutions install BetterDiscord into any Discord or Canary client. What else exactly do you need? 😂 My solution also supports the Discord CANARY Flatpak by the way, unlike the one you use. So my one-liner has more features.

In fact, my solution does error checking along every step of the installation, so it is completely reliable.

Seriously, what else do you need? If you are gonna say "uninstallation" then lmao, why would you uninstall BetterDiscord? And if you do, then it is literally just a matter of deleting the BetterDiscord folder and removing the reference to it from Discord's index.js. Something that doesn't need a script, since it is super obvious from the one-liner exactly where that file resides. But again, why would anyone uninstall BetterDiscord? It is literally a better version of Discord.

I will never use your bloated, pointless script for something so easily solved in 45 words.

as an end user I prefer graphical applications. And betterdiscordctl is at least readable and easy to use.
Instead of complaining and posting a lengthy comment, that nobody cares about, how about you fork betterdicordctl and give a PR back to fix the issues you have with it. (e.g. don't hardcode paths, etc.)
OR, PR this installer and fix the issues in it...

If you don't wanna do either of those, then at least you could have written your comment not as toxic as you did. Just say you would rather use a single line of stacked commands and anyone, who prefers that, there u go.
No need to be so toxic. ^^
