# lib/entertainment-plugin-lib.sh — message-safe helpers for entertainment
|
|
# plugins. Plugins MAY source this (unlike lib/common.sh, whose log/warn/ok
|
|
# chatter would leak into the sent message). Contract: this lib NEVER writes to
|
|
# stdout — helpers print errors to stderr and exit non-zero, so stdout stays the
|
|
# message. Defines only plugin_* names, so it can't collide with common.sh or a
|
|
# plugin's own helpers.
|
|
#
|
|
# Source pattern (works from the repo and from /usr/local/bin after install):
|
|
# source "$(dirname "${BASH_SOURCE[0]}")/../lib/entertainment-plugin-lib.sh" 2>/dev/null \
|
|
# || source "$(dirname "${BASH_SOURCE[0]}")/entertainment-plugin-lib.sh" 2>/dev/null \
|
|
# || source "$(dirname "$0")/../lib/entertainment-plugin-lib.sh" 2>/dev/null \
|
|
# || source "$(dirname "$0")/entertainment-plugin-lib.sh"
|
