Functions ¶
func ComputeChecksum ¶
ComputeChecksum computes the SHA256 checksum of a file.
func ExtractBinary ¶
ExtractBinary extracts the amux binary from a tar.gz archive. Returns the path to the extracted binary.
func GetCurrentBinaryPath ¶
GetCurrentBinaryPath returns the path to the currently running binary.
func GetPlatformAssetName ¶
GetPlatformAssetName returns the expected asset name for the current platform.
func InstallBinary ¶
InstallBinary performs an atomic replacement of the current binary. It stages the new binary in the same directory as the target to avoid cross-filesystem rename issues, then uses rename to atomically swap.
func IsDevBuild ¶
IsDevBuild returns true if this is a development build.
func IsGoInstall ¶
func IsGoInstall() bool
IsGoInstall returns true if the binary appears to be installed via `go install`.
func VerifyChecksum ¶
VerifyChecksum verifies a file's SHA256 checksum.
Types ¶
type Asset ¶
type Asset struct {
Name string `json:"name"`
BrowserDownloadURL string `json:"browser_download_url"`
Size int64 `json:"size"`
ContentType string `json:"content_type"`
}
Asset represents a release asset.
func FindPlatformAsset ¶
FindPlatformAsset finds the appropriate asset for the current platform.
type CheckResult ¶
type CheckResult struct {
CurrentVersion string
LatestVersion string
UpdateAvailable bool
ReleaseNotes string
Release *Release
}
CheckResult contains the result of an update check.
type GitHubClient ¶
type GitHubClient struct {
// contains filtered or unexported fields
}
GitHubClient handles GitHub API interactions.
func NewGitHubClient ¶
func NewGitHubClient() *GitHubClient
NewGitHubClient creates a new GitHub client.
func (*GitHubClient) DownloadAsset ¶

func (*GitHubClient) FetchChecksums ¶
func (c *GitHubClient) FetchChecksums(release *Release) (map[string]string, error)
FetchChecksums downloads and returns the checksums.txt content.
func (*GitHubClient) FetchLatestRelease ¶
func (c *GitHubClient) FetchLatestRelease() (*Release, error)
FetchLatestRelease fetches the latest release from GitHub.
type Release ¶
type Release struct {
TagName string `json:"tag_name"`
Name string `json:"name"`
Body string `json:"body"`
Draft bool `json:"draft"`
Prerelease bool `json:"prerelease"`
