From 0000000000000000000000000000000000000000 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 7bc5bf271e435e1e0d85af133f1352f319f462b5..2acc2a98bd8df6d81b5865b768265a210597b57b 100644 --- a/pom.xml +++ b/pom.xml @@ -44,10 +44,27 @@ compile - jline - jline - 2.12.1 - compile + net.minecrell + terminalconsoleappender + 1.2.0 + + + org.jline + jline-terminal-jansi + 3.12.1 + runtime + + + + org.apache.logging.log4j + log4j-core + 2.8.1 + runtime org.ow2.asm @@ -265,10 +282,18 @@ META-INF/services/java.sql.Driver + + + + com.github.edwgiz + maven-shade-plugin.log4j2-cachefile-transformer + 2.13.1 + + 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 0000000000000000000000000000000000000000..74ed02fa9296583977bb721014b10ff8b708b43c --- /dev/null +++ b/src/main/java/com/destroystokyo/paper/console/PaperConsole.java @@ -0,0 +1,41 @@ +package com.destroystokyo.paper.console;
