func ClearGuesses ¶

func ClearGuesses(ctx context.Context, b api.LanguageBackend)

func GuessWithCache ¶

func GuessWithCache(ctx context.Context, b api.LanguageBackend, forceGuess bool) map[string][]api.PkgName

GuessWithCache returns b.Guess(), but re-uses a cached return value if possible. The cache is used if the matches of b.GuessRegexps against b.FilenamePatterns has not changed since the last time GuessWithCache was invoked. (This is only possible if the backend specifies b.GuessRegexps, which is not always the case. If the backend does specify b.GuessRegexps, then the return value of this function is cached.) If forceGuess is true, then write to but do not read from the cache.

func HasLockfileChanged ¶

func HasLockfileChanged(b api.LanguageBackend) bool

HasLockfileChanged returns false if the lockfile exists and has not changed since the last time UpdateFileHashes was called, or if it doesn't exist and it didn't exist last time either. Otherwise, it returns true.

func HasSpecfileChanged ¶

func HasSpecfileChanged(b api.LanguageBackend) bool

HasSpecfileChanged returns false if the specfile exists and has not changed since the last time UpdateFileHashes was called, or if it doesn't exist and it didn't exist last time either. Otherwise, it returns true.

func Read ¶

func Read(ctx context.Context, b api.LanguageBackend)

func UpdateFileHashes ¶

func UpdateFileHashes(ctx context.Context, b api.LanguageBackend)

UpdateFileHashes caches the current states of the specfile and lockfile. Neither file need exist.

func Write ¶

func Write(ctx context.Context)

Write writes the current contents of the store from memory back to disk. If there is an error, it terminates the process.
