• Executable file install.sh — part of check-in [d123dbf861] at 2026-10-31 18:40:41 on branch main — build: install from GitHub releases with a script; stop publishing to Homebrew

  install.sh installs edgesync and the leaf agent from a GitHub release for macOS or Linux, checking each archive against checksums.txt; a new CI job runs it against the latest release on Ubuntu and macOS. goreleaser no longer updates the danmestas/homebrew-tap formulas, whose leaf formula existed for bones. The README, the docs quickstart and the release notes footer point at the script; the quickstart's library link now names go-libfossil.

# Install EdgeSync from a GitHub release: the edgesync CLI and the leaf agent.
#
#   curl -fsSL https://raw.githubusercontent.com/danmestas/EdgeSync/main/install.sh | sh
#
# Name the binaries to install only some of them:
#
#   curl -fsSL https://raw.githubusercontent.com/danmestas/EdgeSync/main/install.sh | sh -s -- leaf
#
# EDGESYNC_VERSION      release tag to install, e.g. v0.0.21 (default: the latest)
# EDGESYNC_INSTALL_DIR  where the binaries go (default: $HOME/.local/bin)
#
# Each archive is checked against the release's checksums.txt before anything
# is installed. A file curl downloads carries no quarantine flag, so macOS runs
# the binaries without the xattr step a browser download needs.
