bxbot.bat

@echo off

REM
REM Bare bones script for starting BX-bot on Windows systems.
REM
REM Could be made better, but will do for now...
REM
REM You need a Java 21 JDK/JRE installed.
REM
REM This script expects all the jar files to live in the lib_dir.
REM
REM You can change the bxbot_jar var to the version you want to run; it has been defaulted to the current release.
REM
REM You can start, stop, and query the bot's status: bxbot.bat [start|stop|status]
REM
SET lib_dir=.\libs

REM log4j2 config file location
SET log4j2_config=.\config\log4j2.xml

REM The BX-bot 'fat' jar (Spring Boot app containing all the dependencies)
SET bxbot_jar=bxbot-app-2.2.2-SNAPSHOT.jar

REM PID file for checking if bot is running
SET pid_file=.\.bxbot.pid

REM Process args passed to script. Ouch. Is there a Windows equivalent of a Bash 'case' ?
