From cb43684f70ce6bf169893e745001addc1087aa05 Mon Sep 17 00:00:00 2001 From: Minecrell Date: Fri, 9 Jun 2017 19:03:43 +0200 Subject: [PATCH] Use TerminalConsoleAppender for console improvements Rewrite console improvements (console colors, tab completion, persistent input line, ...) using JLine 3.x and TerminalConsoleAppender. New features: - Support console colors for Vanilla commands - Add console colors for warnings and errors - Server can now be turned off safely using CTRL + C. JLine catches the signal and the implementation shuts down the server cleanly. - Support console colors and persistent input line when running in IntelliJ IDEA Other changes: - Server starts 1-2 seconds faster thanks to optimizations in Log4j configuration diff --git a/pom.xml b/pom.xml index 7b9fcb2c0..851646727 100644 --- a/pom.xml +++ b/pom.xml @@ -41,10 +41,27 @@ compile - jline - jline - 2.12.1 - compile + net.minecrell + terminalconsoleappender + 1.1.1 + + + net.java.dev.jna + jna + 4.5.2 + runtime + + + + org.apache.logging.log4j + log4j-core + 2.8.1 + runtime org.ow2.asm @@ -230,10 +247,18 @@ META-INF/services/java.sql.Driver + + + + com.github.edwgiz + maven-shade-plugin.log4j2-cachefile-transformer + 2.8.1 + + org.apache.maven.plugins diff --git a/src/main/java/com/destroystokyo/paper/console/PaperConsole.java b/src/main/java/com/destroystokyo/paper/console/PaperConsole.java new file mode 100644 index 000000000..cd6e25923 --- /dev/null +++ b/src/main/java/com/destroystokyo/paper/console/PaperConsole.java @@ -0,0 +1,40 @@ +package com.destroystokyo.paper.console;
