 Contributing to Forge
 =====================

-1) Keep patches to Minecraft classes together. If you need a lot of things done, you may either add to relevant forge classes or make a new class. Try not to spread out your patches across multiple disjoint lines, as this makes maintenance of your patches difficult.
+1) Keep patches to Minecraft classes minimal. If you need a lot of things done, you may either add to relevant forge classes or make a new class.

-2) TODO: Test Mods
+2) An example mod must be provided for all PRs adding events/hooks to Forge. Whether it's a full mod using your proposed hooks, or just a pastebin containing a simple example, an example mod is required. Please also explain in detail what your new hook does.

-3) Follow the code style of the class you're working in (braces on newlines & spaces instead of tabs in Forge classes, inline brackets in patches, etc).
+3) Follow Forge coding guidelines (braces on newlines, spaces instead of tabs, etc)

- 2. **Forge Discord Server:** You can find a lot of help on the official [Discord Server](https://discord.gg/forge), especially smaller issues that you quickly need help with. *Be aware that the channel is more suited towards development questions, so while you may get support there as a player, you should almost always prefer the forums.*

 A lot of mods also use GitHub or other source management systems and their integrated issue trackers. The following options will give you the best chances of reporting your issue in the right place:

 - **CurseForge:** Many mods are hosted on the [CurseForge platform](https://minecraft.curseforge.com) nowadays. Chances are you already downloaded them from there or as a part of a modpack hosted there. Projects may specify an issue reporting link on their own page, so simply look for it on the mod's project page and you should be directed to the preferred means of error reporting.
- - **Modrinth:** Some modders use [Modrinth](https://modrinth.com/mods) to host their mods, but be mindful that not all mods on this platform are for the Forge modloader.
- - **Searching for a repository directly:** You may need to try and find a repository directly on source control sites. The most common ones are [GitHub](https://github.com), [GitLab](https://gitlab.com), and [BitBucket](https://bitbucket.org). Both come with search capabilities, so simply try to search for the mod's name.

- * An extension point for a mod container.
- *
- * <p>An extension point can be registered for a mod container using {@link ModContainer#registerExtensionPoint(Class, Supplier)}
- * and retrieved (if present) using {@link ModContainer#getCustomExtension(Class)}. An extension point allows a mod to
- * supply an arbitrary value as a record class to another mod or framework through their mod container class, avoiding
- * the use of {@link InterModComms} or other external frameworks to pass around these values.</p>
- *
- * <p>The usual way to declare an extension point is to implement this interface on a record class, with the type
- * parameter being a reference to the class itself. For example, {@code record MyExtension(...) extends
- * IExtensionPoint<MyExtension>} would declare an extension point which supplies a {@code MyExtension} object. However,
- * there is no hard requirement that an extension point's type parameter must be in reference to itself; the type
- * parameter may reference another record class instead.</p>

-     * <p>The {@link Supplier} provides the local compatibility version, which is sent from the server to the client
-     * for multiplayer connections or stored to disk for the world save. The {@link BiPredicate} accepts the remote
-     * compatibility version and a boolean indicating whether the remote version is from the server or a world save,
-     * where {@code true} means it is from the server and {@code false} means it is from the world save. The return

-     * in which case clients will ignore the mod's presence if it is present on the server but not on the client.
-     * However, the remote version test predicate must still accept this value as a remote version in order to display
-     * as compatible if the mod is present on the client.</p>
-     *
-     * <p><strong>The compatibility display test does not necessarily indicate the success or failure of an actual
-     * connection attempt.</strong> Factors such as display test extension misconfiguration, truncation of ping data,
-     * difference of registry data or network channels between server and client, and others may cause the result of the

KnightMiner matyrobbrt ferriarnus	2c3cb2025e	[1.18.x] Backport grindstone event from 1.19 (#9090 ) * Backport grindstone event from 1.19 * Fix several bugs in the original PR related to canceling the event Fix canceling the event not clearing the result item, causing it to dupe whatever the result with the previous item was Fix canceling the event running vanilla behavior if vanilla behavior ran at all since the menu was opened and no other listener changed the XP * Add comments to the test mod explaining the expected behavior * Clarify docs on behavior of the XP Makes it clear XP is ignored in on place if the output is empty or the event is canceled * Fix broadcast changes not being called if the event overrides grindstone behavior Not sure its strictly needed, but every vanilla branch in the function calls it and its a trivial change. * Add enabled flag to the test mod * Improve javadocs (cherry picked from commit `e12c849cc0`) * Formatting fixes * Apply javadoc suggestions from review Co-authored-by: matyrobbrt <[email protected]> * Correct capitalization in event name * Javadoc improvements Remove some redundancy in certain javadoc comments Add @see to the header Inline single line javadocs * Add some funny curly brackets next to returns Seems the kids these days have invented a new way to write return statements in javadocs * Remove extra dots and capital letters The return tag apparently puts more dots at the end, and having two dots on each sentence is not in the budget.
