safe_rel (rebar_safe v1.0.1)

Summary

Functions

compute_checksum_data(Data)

Compute SHA256 checksum of binary data, returns lowercase hex binary.

detect_arch()

detect_os()

download_version(Dir, Version, Checksums)

Download specific SAFE version with checksum verification.

fetch_versions()

Fetch available versions from S3 manifest. The versions.json format is: {"1.0.0": {"macos-x86_64": "sha256", "linux-x86_64": "sha256"}, ...}

get_latest_compatible_version(Constraint)

Get latest version satisfying a constraint, optionally including prereleases. Constraint format: <<"~> 1.3">> (>= 1.3.0, < 2.0.0) or <<"~> 1.3.1">> (>= 1.3.1, < 1.4.0)

get_safe_binary_path(ProjectDir)

Get path to safe binary

sort_versions_desc(Versions)

Sort versions descending (highest first) using semver comparison.

verify_checksum(Actual, Expected)

Verify checksum matches expected value (case-insensitive, trimmed).
