-# Contributing / Development
-Instructions for development setup and upstreaming patches.
+# Contributing
 
-If you just want to build or package quickshell see [BUILD.md](BUILD.md).
+Thank you for taking the time to contribute.
+To ensure nobody's time is wasted, please follow the rules below.
 
-## Development
+## Acceptable Code Contributions
 
-Install the dependencies listed in [BUILD.md](BUILD.md).
-You probably want all of them even if you don't use all of them
-to ensure tests work correctly and avoid passing a bunch of configure
-flags when you need to wipe the build directory.
+- All changes submitted MUST be **fully understood by the submitter**. If you do not know why or how
+  your change works, do not submit it to be merged. You must be able to explain your reasoning
+  for every change.
 
-Quickshell also uses `just` for common development command aliases.
+- Changes MUST be submitted by a human who will be responsible for them. Changes submitted without
+  a human in the loop such as automated tooling and AI Agents are **strictly disallowed**. Accounts
+  responsible for such contribution attempts **will be banned**.
 
-The dependencies are also available as a nix shell or nix flake which we recommend
-using with nix-direnv.
+- Changes MUST respect Quickshell's license and the license of any source works. Changes including
+  code from any other works must disclose the source of the code, explain why it was used, and
+  ensure the license is compatible.
 
-Common aliases:
-- `just configure [<debug|release> [extra cmake args]]` (note that you must specify debug/release to specify extra args)
-- `just build` - runs the build, configuring if not configured already.
-- `just run [args]` - runs quickshell with the given arguments
-- `just clean` - clean up build artifacts. `just clean build` is somewhat common.
+- Changes must follow the guidelines outlined in [HACKING.md](HACKING.md) for style and substance.
 
-### Formatting
-All contributions should be formatted similarly to what already exists.
-Group related functionality together.
+- Changes must stand on their own as a unit. Do not make multiple unrelated changes in one PR.
+  Changes depending on prior merges should be marked as a draft.
 
-Run the formatter using `just fmt`.
-If the results look stupid, fix the clang-format file if possible,
-or disable clang-format in the affected area
-using `// clang-format off` and `// clang-format on`.
+## Acceptable Non-code Contributions
 
-#### Style preferences not caught by clang-format
-These are flexible. You can ignore them if it looks or works better to
-for one reason or another.
+- Bug and crash reports. You must follow the instructions in the issue templates and provide the
+  information requested.
 
-Use `auto` if the type of a variable can be deduced automatically, instead of
-redeclaring the returned value's type. Additionally, auto should be used when a
-constructor takes arguments.
+- Feature requests can be made via Issues. Please check to ensure nobody else has requested the same feature.
 
-```cpp
-auto x = <expr>; // ok
-auto x = QString::number(3); // ok
-QString x; // ok
-QString x = "foo"; // ok
-auto x = QString("foo"); // ok
+- Do not make insubstantial or pointless changes.
 
-auto x = QString(); // avoid
-QString x(); // avoid
-QString x("foo"); // avoid
-```
+- Changes to project rules / policy / governance will not be entertained, except from significant
+  long-term contributors. These changes should not be addressed through contribution channels.
 
-Put newlines around logical units of code, and after closing braces. If the
-most reasonable logical unit of code takes only a single line, it should be
-merged into the next single line logical unit if applicable.
-```cpp
-// multiple units
-auto x = <expr>; // unit 1
-auto y = <expr>; // unit 2
+## Merge timelines

-### Linter
-All contributions should pass the linter.
-
-Note that running the linter requires disabling precompiled
-headers and including the test codepaths:
-```sh
-$ just configure debug -DNO_PCH=ON -DBUILD_TESTING=ON
-$ just lint-changed
-```
-
-If the linter is complaining about something that you think it should not,
-please disable the lint in your MR and explain your reasoning if it isn't obvious.
-
-### Tests
-If you feel like the feature you are working on is very complex or likely to break,
-please write some tests. We will ask you to directly if you send in an MR for an
-overly complex or breakable feature.
-
-At least all tests that passed before your changes should still be passing
-by the time your contribution is ready.
-
-You can run the tests using `just test` but you must enable them first
-using `-DBUILD_TESTING=ON`.
-
-### Documentation
-Most of quickshell's documentation is automatically generated from the source code.
-You should annotate `Q_PROPERTY`s and `Q_INVOKABLE`s with doc comments. Note that the parser
-cannot handle random line breaks and will usually require you to disable clang-format if the
-lines are too long.
-
-Before submitting an MR, if adding new features please make sure the documentation is generated
-reasonably using the `quickshell-docs` repo. We recommend checking it out at `/docs` in this repo.
-
-Doc comments take the form `///` or `///!` (summary) and work with markdown.
-You can reference other types using the `@@[Module.][Type.][member]` shorthand
-where all parts are optional. If module or type are not specified they will
-be inferred as the current module. Member can be a `property`, `function()` or `signal(s)`.
-Look at existing code for how it works.
-
-Quickshell modules additionally have a `module.md` file which contains a summary, description,
-and list of headers to scan for documentation.
-
-## Contributing
-
-### Commits
-Please structure your commit messages as `scope[!]: commit` where
-the scope is something like `core` or `service/mpris`. (pick what has been
-used historically or what makes sense if new). Add `!` for changes that break
-existing APIs or functionality.
-
-Commit descriptions should contain a summary of the changes if they are not
-sufficiently addressed in the commit message.
-
-Please squash/rebase additions or edits to previous changes and follow the
-commit style to keep the history easily searchable at a glance.
-Depending on the change, it is often reasonable to squash it into just
-a single commit. (If you do not follow this we will squash your changes
-for you.)
-
-### Sending patches
-You may contribute by submitting a pull request on github, asking for
-an account on our git server, or emailing patches / git bundles
-directly to `[email protected]`.
-
-### Getting help
-If you're getting stuck, you can come talk to us in the
-[quickshell-development matrix room](https://matrix.to/#/#quickshell-development:outfoxxed.me)
-for help on implementation, conventions, etc.
-Feel free to ask for advice early in your implementation if you are
-unsure.
+We handle work for the most part on a push basis. If your PR has been ignored for a while
+and is still relevant please bump it.

+
+### Linter
+All contributions should pass the linter.
+
+Note that running the linter requires disabling precompiled
+headers and including the test codepaths:
+```sh
+$ just configure debug -DNO_PCH=ON -DBUILD_TESTING=ON
+$ just lint-changed
+```
+
+If the linter is complaining about something that you think it should not,
+please disable the lint in your MR and explain your reasoning if it isn't obvious.
+
+### Tests
+If you feel like the feature you are working on is very complex or likely to break,
+please write some tests. We will ask you to directly if you send in an MR for an
+overly complex or breakable feature.
+
+At least all tests that passed before your changes should still be passing
+by the time your contribution is ready.
+
+You can run the tests using `just test` but you must enable them first
+using `-DBUILD_TESTING=ON`.
+
+### Documentation
+Most of quickshell's documentation is automatically generated from the source code.
+You should annotate `Q_PROPERTY`s and `Q_INVOKABLE`s with doc comments. Note that the parser
+cannot handle random line breaks and will usually require you to disable clang-format if the
+lines are too long.
+
+Make sure new files containing doc comments are added to a `module.md` file.
+See existing module files for reference.
+
+Doc comments take the form `///` or `///!` (summary) and work with markdown.
+You can reference other types using the `@@[Module.][Type.][member]` shorthand
+where all parts are optional. If module or type are not specified they will
+be inferred as the current module. Member can be a `property`, `function()` or `signal(s)`.
+Look at existing code for how it works.
+
+If you have made a user visible change since the last tagged release, describe it in
+[changelog/next.md](changelog/next.md).
+
+## Contributing
+
+### Commits
+Please structure your commit messages as `scope: commit` where
+the scope is something like `core` or `service/mpris`. (pick what has been
+used historically or what makes sense if new).
+
+Commit descriptions should contain a summary of the changes if they are not
+sufficiently addressed in the commit message.
+
+Please squash/rebase additions or edits to previous changes and follow the
+commit style to keep the history easily searchable at a glance.
+Depending on the change, it is often reasonable to squash it into just
+a single commit. (If you do not follow this we will squash your changes
+for you.)
+
+### Getting help
+If you're getting stuck, you can come talk to us in the
+[quickshell-development matrix room](https://matrix.to/#/#quickshell-development:outfoxxed.me)
+for help on implementation, conventions, etc. There is also a bridged [discord server](https://discord.gg/UtZeT3xNyT).
+Feel free to ask for advice early in your implementation if you are
+unsure.

-## Breaking Changes
-
-### Config paths are no longer canonicalized
-
-This fixes nix configs changing shell-ids on rebuild as the shell id is now derived from
-the symlink path. Configs with a symlink in their path will have a different shell id.
-
-Shell ids are used to derive the default config / state / cache folders, so those files
-will need to be manually moved if using a config behind a symlinked path without an explicitly
-set shell id.
-
-## New Features
-
-- Added support for creating Polkit agents.
-- Added support for creating wayland idle inhibitors.
-- Added support for wayland idle timeouts.
-- Added support for inhibiting wayland compositor shortcuts for focused windows.
-- Added the ability to override Quickshell.cacheDir with a custom path.
-- Added minimized, maximized, and fullscreen properties to FloatingWindow.
-- Added the ability to handle move and resize events to FloatingWindow.
-- Pipewire service now reconnects if pipewire dies or a protocol error occurs.
-- Added pipewire audio peak detection.
-- Added initial support for network management.
-- Added support for grabbing focus from popup windows.
-- Added support for IPC signal listeners.
-- Added Quickshell version checking and version gated preprocessing.
-- Added a way to detect if an icon is from the system icon theme or not.
-- Added vulkan support to screencopy.
-
-## Other Changes
-
-- FreeBSD is now partially supported.
-- IPC operations filter available instances to the current display connection by default.
-- PwNodeLinkTracker ignores sound level monitoring programs.
-
-## Bug Fixes
-
-- Fixed volume control breaking with pipewire pro audio mode.
-- Fixed volume control breaking with bluez streams and potentially others.
-- Fixed volume control breaking for devices without route definitions.
-- Fixed escape sequence handling in desktop entries.
-- Fixed volumes not initializing if a pipewire device was already loaded before its node.
-- Fixed hyprland active toplevel not resetting after window closes.
-- Fixed hyprland ipc window names and titles being reversed.
-- Fixed missing signals for system tray item title and description updates.
-- Fixed asynchronous loaders not working after reload.
-- Fixed asynchronous loaders not working before window creation.
-- Fixed memory leak in IPC handlers.
-- Fixed ClippingRectangle related crashes.
-- Fixed crashes when monitors are unplugged.
-- Fixed crashes when default pipewire devices are lost.
-
-## Packaging Changes
-
-`glib` and `polkit` have been added as dependencies when compiling with polkit agent support.
-`vulkan-headers` has been added as a build-time dependency for screencopy (Vulkan backend support).

+
+## Other Changes
+

+- PwNodeLinkTracker ignores sound level monitoring programs.
+- Replaced breakpad with cpptrace.
+- Reloads are prevented if no file content has changed.
+- Added `QS_DISABLE_FILE_WATCHER` environment variable to disable file watching.
+- Added `QS_DISABLE_CRASH_HANDLER` environment variable to disable crash handling.
+- Added `QS_CRASHREPORT_URL` environment variable to allow overriding the crash reporter link.
+- Added `AppId` pragma and `QS_APP_ID` environment variable to allow overriding the desktop application ID.
+- Added `DropExpensiveFonts` pragma and `QS_DROP_EXPENSIVE_FONTS` environment variable which avoids loading fonts which may cause lag and excessive memory usage if many variants are used.
+- Added `DefaultEnv` pragma which sets an environment variable if not already set.
+- Unrecognized pragmas are no longer a hard error for future backward compatibility.

+- Worked around Qt bug causing crashes when plugging and unplugging monitors.
+- Fixed HyprlandFocusGrab crashing if windows were destroyed after being passed to it.
+- Fixed ScreencopyView pixelation when scaled.
+- Fixed JsonAdapter crashing and providing bad data on read when using JsonObject.
+- Fixed JsonAdapter sending unnecessary property changes for primitive values.
+- Fixed JsonAdapter serialization for lists.
+- Fixed pipewire crashes after hotplugging devices and changing default outputs.
+- Fixed launches failing for `--daemonize` on some systems.
+- Fixed screencopy crashing when used across GPUs.
+- Fixed pipewire volumes not working for some pw-pulse clients.

+
+## Packaging Changes
+
+- `glib` and `polkit` have been added as dependencies when compiling with polkit agent support.
+- `vulkan-headers` has been added as a build-time dependency for screencopy (Vulkan backend support).
+- `breakpad` has been replaced by `cpptrace`, which is far easier to package, and the `CRASH_REPORTER` cmake variable has been replaced with `CRASH_HANDLER` to stop this from being easy to ignore.
+- `DISTRIBUTOR_DEBUGINFO_AVAILABLE` was removed as it is no longer important without breakpad.
+- `libdrm` is now unconditionally required as a direct dependency.
