go-selfupdate

Self-Update library for GitHub hosted applications in Go

go-selfupdate detects the information of the latest release via GitHub Releases API and checks the current version. If a newer version than itself is detected, it downloads the released binary from GitHub and replaces itself.

• Automatically detect the latest version of released binary on GitHub
• Retrieve the proper binary for the OS and arch where the binary is running
• Update the binary with rollback support on failure
• Tested on Linux, macOS and Windows
• Many archive and compression formats are supported (zip, tar, gzip, xzip, bzip2)
• Support private repositories
• Support hash, signature validation

This library started as a fork of https://github.com/rhysd/go-github-selfupdate. A few things have changed from the original implementation:

• don't expose an external semver.Version type, but provide the same functionality through the API: LessThan, Equal and GreaterThan
• use an interface to send logs (compatible with standard log.Logger)
• able to detect different ARM CPU architectures (the original library wasn't working on my bakery of raspberry pi)
• support for assets compressed with bzip2 (.bz2)
