* [Settings] Back up the settings folder before migrating The per-file settings migration only preserved global.ini, as global.ini.old. Everything else the migrations write was overwritten in place with no way back: the legacy migration and the 17 per-domain migrateXxxSettings functions all write straight into the per-domain .ini files, so any of them that got a key mapping wrong silently replaced a working file. The re-migration path is the sharpest case, because migrateSettingsFromGlobalIni() runs again whenever an older build wrote non-sentinel keys back into global.ini, and those values then land on top of per-domain files the user had already edited. Snapshot the whole settings folder before either migration runs, into a timestamped sibling settings-backup-<yyyyMMdd-HHmmss>. A sibling rather than a child, so a backup is never copied into the next backup and the "Open Settings Folder" action keeps showing only live files. Keep every snapshot; settings files are kilobytes, so growth is not a concern. SettingsMigration::isMigrationPending() gates the copy so a normal start creates nothing. It reuses the same condition migrateSettingsFromGlobalIni() uses to decide whether it has work, factored into a shared helper so the two cannot drift, and it ignores the legacy migration on an empty profile where that migration only writes its sentinel. The backup itself skips a folder whose files are all empty, which covers a fresh profile whose global.ini was created but never written. A failed copy logs a warning and returns an empty path rather than aborting the migration, since a full disk or an unwritable data folder must not leave the client unable to start. global.ini.old still works as the single-file escape hatch. Document the folder layout, the automatic backups, and the fact that migrations only run forwards, so users know to copy the settings folder before downgrading to a version that cannot read the per-group files. * [Client] Match the desktop file name case for the portal app ID QGuiApplication::setDesktopFileName() was given "Cockatrice"/"Oracle" while the installed desktop entries are cockatrice.desktop and oracle.desktop. Linux paths are case-sensitive, so xdg-desktop-portal failed the app-info lookup for "Cockatrice" and Qt warned on every QDesktopServices call that it could not register with the host portal. The same string becomes the xdg-shell appId, so the window icon lookup failed on Wayland for the same reason. --------- Co-authored-by: Lukas Brübach <Bruebach.Lukas@bdosecurity.de>

Cockatrice
Cockatrice is an open-source, multiplatform application for playing tabletop card games over a network. The program's server design prevents users from manipulating the game for unfair advantage. The client also provides a single-player mode, which allows users to brew while offline.
This project uses C++ and the Qt libraries.

Repository Activity
Code
To contribute code to the project, please review our guidelines first.
We maintain two tags for contributors to easier find issues to potentially work on:
Issues tagged in this way provide a simple way to get started. They don't require much experience to be worked on.
This tag is used for issues that we are looking for somebody to pick up. Often this is for feature suggestions we support, but don't have the time to work on ourselves.
For both tags, we're willing to provide help to contributors in showing them where and how they can make changes, as well as code reviews for submitted changes.
We'll happily advice on how best to implement a feature, or we can show you where the codebase is doing something similar before you get too far along - put a note on an issue you want to discuss more on!
You can also have a look at our Todo List in our Code Documentation or search the repo for \todo comments.
Documentation 
There are various places where useful information for different needs are maintained:
- Official Code Documentation
- Official Wiki
Community supported - Official Webpage
- Official README
This file
Cockatrice tries to use the Google Developer Documentation Style Guide to ensure consistent documentation. We encourage you to improve the documentation by suggesting edits based on this guide.
Translation 
Cockatrice uses Transifex to manage translations. You can help us bring Cockatrice and Oracle to your language and just adjust single wordings right from within your browser by visiting our Transifex project page. The Webatrice web client manages its own translations in its repo.
Check out our Translator FAQ for more information about getting involved, and join a group of hundreds of others!
Build 
Dependencies: (for minimum versions search our CMake file)
Oracle can optionally use some packages to load compressed card files:
Basic compilation steps:
mkdir build
cd build
cmake ..
make
You can then
- Create a Cockatrice installation inside the
releasefolder:make install - Or make an installation package specific to your system:
make package
Note
Detailed compiling instructions can be found in the Cockatrice wiki at Compiling Cockatrice
The following flags (with their non-default values) can be passed to cmake:
| Flag | Description |
|---|---|
-DWITH_SERVER=1 |
Build Servatrice server |
-DWITH_CLIENT=0 |
Don't build Cockatrice client |
-DWITH_ORACLE=0 |
Don't build Oracle card database tool |
-DCMAKE_BUILD_TYPE=Debug |
Compile in debug mode Enables extra logging output, debug symbols, and much more verbose compiler warnings |
-DWARNING_AS_ERROR=0 |
Don't treat compilation warnings as errors in debug mode |
-DUPDATE_TRANSLATIONS=1 |
Configure make to update the translation .ts files for new strings in the source codeNote: make clean will remove the .ts files |
-DTEST=1 |
Enable regression tests Note: make test to run tests, googletest will be downloaded if not available |
Run
Cockatrice is the game client
Oracle fetches card data
Servatrice is the server
Docker
You can build an image & deploy a Servatrice (Cockatrice server) container using Docker and our Dockerfile yourself.
For more details, look into our wiki section on Setting up Servatrice.
You'll also find more hints on our pre-build image there, or the docker-compose file which will configure and run both a MySQL server and Servatrice.
