# autorender.sh — self-updating nightly render driver for the render rig.
|
|
#
|
|
# Invoked by Windows Task Scheduler (run only when user is logged on):
|
|
# wsl.exe -d Ubuntu -u glitchhunter -- bash -lc "/home/glitchhunter/Projects/gnommo/autorender.sh"
|
|
#
|
|
# Flow:
|
|
# 1. DEPLOY CODE — git fetch + reset --hard origin/<branch>, then re-exec the
|
|
# freshly pulled script once. This is how code changes ship from the Mac:
|
|
# push to origin, and the next run picks them up. SAFE — reset --hard only
|
|
# rewrites TRACKED files; gitignored project data (video*/) and secrets
|
|
# (.env) are left untouched. This script NEVER runs `git clean`.
|
|
# 2. RENDER — (pending) `gnommo auto`: per-project down -> gated render -> handoff.
|
|
#
|
|
# Config via environment (set once in ~/.profile / ~/.bash_profile on the rig,
|
|
# so a login shell — bash -lc — picks them up):
|
|
# GNOMMO_DIR repo clone on the rig (default: this script's own dir)
|
|
# BRANCH branch to track (default: main)
|
|
# NTFY_URL failure ping endpoint, e.g. https://ntfy.sh/your-secret-topic

# username or checkout path (rig: /home/glitchhunter/Projects/gnommo).
