Vommet

Commet, but with added slop™.

A downstream, LLM-assisted fork of the Commet Matrix client.

This is a fork. It is not Commet, and the Commet maintainers are not responsible for it.

Vommet exists to iterate quickly on the papercuts that keep people on Discord and off Matrix. Compatibility with the Nether voice bridges is a priority. "Vommet" is a codename and will change before anything resembling a 1.0.

Please read before filing anything

• Most code here was written with the help of an LLM. Commet's contribution policy prohibits that, which we respect: nothing from this fork is ever submitted upstream, and we don't post LLM output in their spaces. If that policy matters to you, this fork is not for you — use Commet.
• Bugs in this fork belong here, in this repo's issue tracker, never in Commet's. If you are not sure whether a bug is ours or upstream's, file it here first.
• This is a soft fork. Our changes are a patch stack on top of Commet's main; the overwhelming majority of the code is theirs. Consider donating to Commet.

What's different so far

In main:

• Its own identity: app id im.nether.chat (installs side by side with Commet), name and icons.
• Third-party requests (GIF search, sticker import) go through our own proxy, vommet-proxy, never through Commet's servers.
• Update checks are off (Commet's update feed describes Commet, not us), and Android uses UnifiedPush only (no Firebase).

On the testing branch, waiting for hands-on testing:

• Telegram sticker and custom-emoji import — paste a t.me/addstickers/… link; animated Telegram stickers are converted to animated WebP by the proxy (#2).
• Picture mosaics — several pictures posted together show as one Telegram-style grid (#11).
• Room banners for ordinary rooms, not just spaces (#6).
• Search when adding existing rooms to a space (#10).
• "Copy selection" in the desktop message menu (#9).
• The Vommet name and logo everywhere in the app.
• Builds: signed Android APKs and a Flatpak for testers.

Plans

• Voice isolation on par with Discord — RNNoise-based noise suppression on desktop first (#3).
• Screen share with sound on Linux and Windows (#4).
• Join voice calls in ordinary text rooms, like Discord (#8).
• Sliding sync for faster startup on big accounts (#5).
• Fix random startup crashes on Arch Linux (#7).
• Copying part of a message on mobile (#9).
• Easier installs: a Flatpak repository with updates, and Windows builds.

Ideas and complaints welcome on the issue tracker. The full list of differences from Commet is in VOMMET_CHANGES.md.

Development

To build, you require Flutter, currently v3.41.9

This repo currently has a monorepo structure, containing two flutter projects: Commet and Tiamat. Commet is the main client, and Tiamat is a sort of wrapper around Material with some extra goodies, which is used to maintain a consistent style across the app. Tiamat may eventually be moved to its own repo, but for now it is maintained here for ease of development.

Building

1. Install Flutter

2. Install Libraries

Commet requires some additional libraries to be built

sudo apt-get install -y cmake clang ninja-build rustup libgtk-3-dev libmpv-dev mpv ffmpeg libmimalloc-dev libwebkit2gtk-4.1-dev keybinder-3.0

3. Fetch Dependencies

You will need to change directory in to the project, then fetch dependencies

cd commet
flutter pub get

4. Code Generation

We make use of procedural code generation in some parts of the project. As a rule, generated code will not be checked in to git, and will need to be generated before building.

To run code generation, run the script within the commet directory: dart run scripts/codegen.dart

5. Building

When building, there are some additional command line arguments that must be used to configure the build.

Required

Argument	Valid Values	Description
PLATFORM	'desktop', 'mobile', 'linux', 'windows', 'macos', 'android', 'ios', 'web'	Defines which platform to build for
BUILD_MODE	'release', 'debug'	When building with 'debug' flag, additional debug information will be shown

Optional

Argument	Valid Values	Description
GIT_HASH	*	Supply the current git hash when building to show in info screen
VERSION_TAG	*	Supply the current build version, to display app version
BUILD_DETAIL	*	Can provide additional detail about the current build, for example if it was being built for Flatpak or Snap

Example:

cd commet
flutter run --dart-define BUILD_MODE=debug --dart-define PLATFORM=linux
