Creates .venv/ with python3 -m venv if not present, then installs/ updates requirements.txt into it before setting up the systemd service. The service ExecStart always uses the venv Python. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

# Install we_monitor as a systemd user service.
|
|
#
|
|
# What this script does:
|
|
# 1. Creates ~/.config/we_monitor/ and a credentials template if missing
|
|
# 2. Writes a systemd user service unit
|
|
# 3. Enables the service (does not start it — edit credentials first)
|
|
#
|
|
# Usage:
|
|
# chmod +x install.sh
|
|
# ./install.sh
|
|
# # then edit ~/.config/we_monitor/credentials.json
|
|
# systemctl --user start we_monitor
|
