Discord protocol

[Vulpix]

This topic is dedicated to Discord protocol development and alpha-testing.

Current state can be seen @ first post on github: https://github.com/miranda-ng/miranda-ng/issues/629

[Vulpix]

What should work:
- 1on1 chats including message history syncing and offline messages (both sending and receiving)
- changing avatar + viewing other people's avatars
- chatting in guild (group) chats you are already a part of
- adding a new friend
- accepting a friend request
- changing status (Offline, Online, NA=idle, DND)
- websocket gateway

What doesn't work but can likely be made to work
- 2FA
- File transfers
- Joining new guilds/leaving guilds (groupchats) - you have to do it from within the discord program or website and relog to discord
- Joining/leaving channels
- Miranda doesn't reflect status change made in different endpoint (i.e. if you change your status in browser discord, miranda will not reflect that)
- likely none of the nitro features

File transfers are being worked on. I believe.

Please test and see for yourself.

See first post!

Please be aware that miranda attempts to sync all of your histories when you start it and if you have a long history with direct messaging with someone, it may take a while.

I would like to give it a try, but i can't load x64 development version of the plugin with the latest dev build of Miranda on Windows 10 x64.

Code: [Select]

The ordinal 397 could not be located in the dynamic link library <Miranda Root>\Plugins\Discord.dll.I tried scouting the plugin with Dependency Walker, but i can't spot anything unusual. Does it require some additional MSVC++ libraries? I've got all ordinary MSVC++ redistributables installed.

you're using the stable version right now, you cannot load just one new plugin and try to launch it under this version.
go to Options - Services - Plugin updater, switch to the Development version (with or without symbols) and update everything first

My bad, it seems, I've left silent update mode enabled. Surprisingly, i tried skypeweb alpha about a year ago the same way and it never complained about compile options mismatch.

Impressive. I briefly compared running standalone client next to a plugin.

First of all, amazing job. Discord standalone client consumes more than a 100mb of RAM, while miranda is under 10mb for many protocols at once. That's a major debloating for something as basic as text IM when voice chat is not required.

Online status seems to work fine, however, client sees itself as online in group chats lists even when invisible, but it's probably an intended behavior.

Most of the unimplemented stuff, unsurprisingly, goes under group chats.

Group chat nicknames are not working (everyone is displayed as accountname#nnnn, including own name). I assume, this is because discord user can have unique nickname on per-group basis and it's not supported yet.
Group chat motd/channel title is not displayed in group chat window.
Group chat direct highlights don't work yet (@nickname as seen in Discord becomes <@nnnnnnnnnnnnnnnnn> in Miranda).
Group chat channel highlights are not decyphered (<#nnnnnnnnnnnnnnnnnnn> instead of #channel in Discord).
Group chat log is named after internal channel id (nnnnnnnnnnnnnnnnnnn.log) instead of group#channel.log.
Users with group chat moderation rights are not marked or highlighted via color in the channel chat window in any way.

The biggest disadvantage compared to native discord is probably the lack of discord group chat history sync (i.e. listing messages sent per channel while offline). Is this supported in miranda globally? I've noticed this is most likely the case with skypeweb and other group chats, excluding third-party assisted (IRC BNC services).

Thanks for keeping desktop instant messaging alive.

Yeah, group chats were somewhat "out of scope" (or rather the message syncing) when I posted bounty on the discord support ( https://github.com/miranda-ng/miranda-ng/issues/629#issuecomment-268559665 )

Ghazan has done an amazing job implementing it because for better or worse, the actual messaging is not documented in the API.

At any rate, miranda isn't all that great for group chat history and syncing right now; we don't save history (we can log it into a text file) and in general group chats are handled differently than regular 1on1 conversations.

But I'm sure ghazan could make it work eventually :p hehe.

Experienced a random crash today after messaging someone:

Impressive. I briefly compared running standalone client next to a plugin.

Well, the "standalone client" is nothing but a Chromium, that executes tons of js So it's not so hard to outperform it considering RAM usage, though Miranda always was (and forever will be) very concerned about memory footprint :-)

First of all, amazing job. Discord standalone client consumes more than a 100mb of RAM, while miranda is under 10mb for many protocols at once. That's a major debloating for something as basic as text IM when voice chat is not required.

Thanks for the flattering review, the fact is that this plugin is in the very beginning, so your opinions and remarks are greatly appreciated. I'll implement them when I have spare time.

[ghazan]

Group chat nicknames are not working (everyone is displayed as accountname#nnnn, including own name). I assume, this is because discord user can have unique nickname on per-group basis and it's not supported yet.

done. also I implemented joining / leaving guilds on the fly

[ghazan]

now we can change our own nickname in chats

[Vulpix]

now we can change our own nickname in chats

Already more advanced than Skype where you cannot change your nickname..

I actually had to roll back to previous discord because today's one wouldn't let me log in It'd always disconnect me silently ~1-2 seconds after login.

[mnguser]

I've noticed group leaving messages showing up and some of the names in the chat list are now displayed without numeric index (#nnnn). Good job!
Aslo noticed, that picture attachments in group chats are displayed as clickable links and don't require auth to view from browser, so at least this doesn't require additional hassle to make it work, as opposed to skype.
