From 0140f0a679cb39eb069e0ea08f22775885ee9a16 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: - Update JLine to 3.3.1 (from 2.12.1) - Server starts 1-2 seconds faster thanks to optimizations in Log4j configuration diff --git a/pom.xml b/pom.xml index 9d273c6d9..26775156b 100644 --- a/pom.xml +++ b/pom.xml @@ -53,12 +53,6 @@ 5.0.4 compile - - jline - jline - 2.12.1 - compile - org.xerial sqlite-jdbc @@ -77,6 +71,32 @@ 3.0.3 compile + + + net.minecrell + terminalconsoleappender + 1.0.0 + + + net.java.dev.jna + jna + 4.4.0 + runtime + + + + + org.apache.logging.log4j + log4j-core + 2.8.1 + runtime + + junit @@ -210,10 +230,18 @@ 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/TerminalConsoleCommandSender.java b/src/main/java/com/destroystokyo/paper/console/TerminalConsoleCommandSender.java new file mode 100644 index 000000000..685deaa0e --- /dev/null +++ b/src/main/java/com/destroystokyo/paper/console/TerminalConsoleCommandSender.java @@ -0,0 +1,17 @@ +package com.destroystokyo.paper.console;
