Functions

func CheckSyncDBs

func CheckSyncDBs(names []string, dbPath string) (found []string)

func CompareVersions

func CompareVersions(a, b string) int

CompareVersions uses libalpm's logic to compare two versions of arbitrary formats. The return value is negative when a is less than b, zero when a and b are equal, and positive when b is greater than a.

func GetConfigRepos

func GetConfigRepos(path string) (names []string, err error)

GetConfigRepos loads the specified pacman configuration file at path and extracts any configured repository names. Any error is returned with an explanatory message in err.

func GetForeignPackages

func GetForeignPackages(root, dbPath string, repos []string) (pkgs map[string]string, err error)

func GetLocalPackages

func GetLocalPackages(root, dbPath string) (pkgs map[string]string, err error)

GetLocalPackages retrieves the list of locally-installed pkgs. Keys are package names and values are their versions. If an error is encountered it is returned in err.

func GetSyncPackages

func GetSyncPackages(root, dbPath string, repos []string) (pkgs map[string]string, err error)

GetSyncPackages retrieves the list of known packages for the specified repos. Keys are package names and values are their versions. If an error is encountered it is returned in err.
