# run_radio.sh - Launcher for the radio automation JRuby scripts.
#!/bin/bash
# run_radio.sh - Self-locating launcher for the JRuby radio automation scripts.
#
# Sets GEM_HOME/GEM_PATH in the environment BEFORE jruby boots, because
# mutating those variables inside a running JRuby process does not reliably
# affect gem resolution (JRuby issue #5269). Setting them pre-boot lets
# RubyGems pick them up natively. Self-locating, so the whole tree can be
# relocated without editing anything.
# Why a launcher: mutating GEM_HOME/GEM_PATH inside a running JRuby process does
# not reliably affect gem resolution (JRuby #5269). Exporting them BEFORE jruby
# boots is the reliable path. This script derives its own location, points the
# gem env at the co-located .gems dir, passes a bounded JVM heap, and execs
# jruby with the requested script + args. The .rb scripts keep a portable
# "#!/usr/bin/env jruby" shebang and are invoked THROUGH this launcher.
#
# Usage: ./run_radio.sh <script.rb> [args...]
# e.g. ./run_radio.sh fetch_podcasts.rb --list-shows
# Heap sizing: feed parsing is streamed to disk (constant memory), but episode
# downloads buffer per-file, so we give the JVM a comfortable-but-capped ceiling.
# NOTE: this JRuby build ignores JRUBY_OPTS, so JVM flags must be passed on the
# command line via -J (e.g. -J-Xmx2g), not through an environment variable.
#
# Usage:
# ./run_radio.sh <script.rb> [args...]
# sudo -u liquidsoap ./run_radio.sh fetch_podcasts.rb --add-show <url>
