Describe your issue

When opening the emote menu in contexts where a channel doesn't exist (/mentions, /whispers, /automod, /live, etc.), then typing anything into the search bar, Chatterino will crash.

Steps to reproduce:

Create a new/navigate to a /live tab
Open the emote menu with the chat box button or Ctrl+E
Type anything into the search bar
Observe the crash

OS and Chatterino Version

Chatterino 2.5.3 (commit 3f3a31d) built with Qt 6.7.1, MSVC 194334808, Crashpad Running on Windows 10 Version 22H2, kernel: 10.0.19045

Additionally, both sub and global emotes don't load when there's no channel context. Emojis still work as expected.

Bad	Good	Bad	Good

This would be a good first issue for someone wanting to try out some Chatterino development.

The problem comes from the emote popup (src/widgets/dialogs/EmotePopup.cpp)'s filterEmotes function trying to perform actions on the searchView_'s underlying channel. However, the underlying channel can be null, so we need to check that before attempting to use it.

If someone is interesting in taking this task on and runs into any issues, feel free to use this issue to ask those questions, or ask in our Discord.

I can submit a PR for this, just fighting with vcpkg first 😅

Hmmm, vcpkg is complaining about a checksum mismatch for boost-variant2. Downloading the archive through my browser also leads to the same SHA512 hash as the actual from vcpkg.

I've tried re-cloning vcpkg but it still throws the error. Do you have any ideas on what might be wrong?

Edit: I tried on a second device and have the exact same checksum issue. I think boost might have modified the archive without updating the associated checksum?

Hmmm, vcpkg is complaining about a checksum mismatch for boost-variant2. Downloading the archive through my browser also leads to the same SHA512 hash as the actual from vcpkg.

Have you tried bumping the baseline? Maybe the packages are out of date or something. Feel free to make a PR if that fixed it.

That worked! I'll submit a PR with the updated baseline.

It seems that vcpkg is no longer able to fetch Qt though. BUILDING_ON_WINDOWS_WITH_VCPKG should probably be updated to mention that manually installing Qt is now required like in BUILDING_ON_WINDOWS. I can also make a PR for that if wanted. Never mind, I just installed Qt manually and I'm still getting CMake errors.
