displayClientMessage(Component, boolean) was removed from LocalPlayer
in 26.2. sendSystemMessage(Component) is inherited from Entity, has
been part of Mojang's public API since 1.19, and LocalPlayer overrides
it to route the message into the local chat hud, which is exactly the
behaviour we want.
Gui.chat is private in 26.2 and Gui.getChat() is gone, so the previous
direct-field access does not compile. Player.displayClientMessage is a
public, stable API for client-side chat output, so push everything
through it. When the player is null (e.g. on the title screen before
join, where the auto-connect "Connected to ..." line lands), fall back
to the logger so the message is not silently dropped.
In 26.2 Mojang dropped the getChat() wrapper on Gui in favour of the
public 'chat' field, and com.mojang.authlib.GameProfile is now a record
so its getter is name() rather than getName(). Reflect both changes in
the IRC chat dispatcher.
Starting with 26.1 Mojang ships Minecraft unobfuscated, and Yarn /
Intermediary are no longer published past 1.21.11. Loom does not need
a mappings dependency in that mode: the Mojang-named source compiles
directly. Remove the mappings line, drop the yarn_mappings property,
revert the client entrypoint to Mojang names (Minecraft, Component,
ChatFormatting, gui.getChat(), getUser().getName()), and rewrite the
README note so it stops claiming Mojang mappings via Loom.
Loom rejected officialMojangMappings() with a non-obfuscated
environment error, and Mojang client_mappings are not published for
26.2 yet. Pin Yarn at 26.2+build.3 via the new yarn_mappings property
and rewrite the client entrypoint with Yarn names: MinecraftClient,
Text, Formatting, inGameHud.getChatHud(), getSession().getUsername().
Auto-connect on CLIENT_STARTED, .irc reconnect and .irc <msg> all used
to open a TCP socket on the render thread with a 5s connect timeout,
freezing client startup and chat input when the server was unreachable.
Dispatch those paths through a single daemon executor instead, and
release the socket plus the executor on CLIENT_STOPPING.
