MSVC and MinGW Setup .exe both matched 'setup.*.exe'; tightened the include pattern to 'msvc-setup.*.exe' so exactly one candidate resolves. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

# fetch-launcher.sh — download all FjordLauncherUnlocked release assets for
|
|
# offline LAN hosting, then create stable-name symlinks for the landing page.
|
|
#
|
|
# Guests use FjordLauncherUnlocked (Prism/PolyMC fork with authlib-injector
|
|
# built in). We mirror every release asset under mirror/launcher/<tag>/ and
|
|
# maintain a `latest` symlink → <tag>. Caddy serves this at /launcher/latest/…
|
|
#
|
|
# The landing page (landing/src/data/site.ts) links to FIXED filenames so the
|
|
# links survive launcher version bumps. After download this script resolves and
|
|
# symlinks those stable names to the real versioned assets:
|
|
# fjord-windows-setup.exe → Windows Setup .exe (x64)
|
|
# fjord-macos.dmg → macOS .dmg
|
|
# fjord-linux-x86_64.AppImage → Linux x86_64 .AppImage
|
|
#
|
|
# Cautious by design: halts on any error, and if a stable-name category matches
|
|
# 0 or >1 candidate it prints the candidates and exits non-zero rather than
|
|
# guessing. Idempotent — re-runs overwrite symlinks and re-download safely.
|
|
# mirror/ is gitignored — only this script is tracked.
