Functions

func CheckClose 

func CheckClose(c io.Closer, err *error)

CheckClose is a utility function used to check the return from Close in a defer statement.

func CompareDirEntries 

func CompareDirEntries(a, b DirEntry) int

CompareDirEntries returns 1 if a > b, 0 if a == b and -1 if a < b If two dir entries have the same name, compare their types (directories are before objects)

func ConfigMap 

func ConfigMap(fsInfo *RegInfo, configName string, connectionStringConfig configmap.Simple) (config *configmap.Map)

ConfigMap creates a configmap.Map from the *RegInfo and the configName passed in. If connectionStringConfig has any entries (it may be nil), then it will be added to the lookup with the highest priority.

If fsInfo is nil then the returned configmap.Map should only be used for reading non backend specific parameters, such as "type".

func ConfigOAuthOnly 

func ConfigOAuthOnly(ctx context.Context) context.Context

ConfigOAuthOnly marks the ctx so that the Config will stop after finding an OAuth

func ConfigString 

func ConfigString(f Fs) string

func ConfigStringFull 

func ConfigStringFull(f Fs) string

ConfigStringFull returns a canonical version of the config string used to configure the Fs as passed to fs.NewFs. This string can be used to re-instantiate the Fs exactly so includes all the extra parameters passed in.

ConfigToEnv converts a config section and name, e.g. ("my-remote", "ignore-size") into an environment name "RCLONE_CONFIG_MY-REMOTE_IGNORE_SIZE"

func CopyConfig 

func CopyConfig(dstCtx, srcCtx context.Context) context.Context

CopyConfig copies the global config (if any) from srcCtx into dstCtx returning the new context.

func Debugf 

func Debugf(o interface{}, text string, args ...interface{})

Debugf writes debugging output for this Object or Fs. Use this for debug only. The user must have to specify -vv to see this.

func DirEntryType 

func DirEntryType(d DirEntry) string

DirEntryType returns a string description of the DirEntry, either "object", "directory" or "unknown type XXX"

func DirectoryOptionalInterfaces 

func DirectoryOptionalInterfaces(d Directory) (supported, unsupported []string)

FileExists returns true if a file remote exists. If remote is a directory, FileExists returns false.

func Fingerprint 

func Fingerprint(ctx context.Context, o ObjectInfo, fast bool) string

Fingerprint produces a unique-ish string for an object.

This is for detecting whether an object has changed since we last saw it, not for checking object identity between two different remotes - operations.Equal should be used for that.

If fast is set then Fingerprint will only include attributes where usually another operation is not required to fetch them. For example if fast is set then this won't include hashes on the local backend.

func FixRangeOption 

func FixRangeOption(options []OpenOption, size int64)

FixRangeOption looks through the slice of options and adjusts any RangeOption~s found that request a fetch from the end into an absolute fetch using the size passed in and makes sure the range does not exceed filesize. Some remotes (e.g. Onedrive, Box) don't support range requests which index from the end.

It also adjusts any SeekOption~s, turning them into absolute RangeOption~s instead.

func GetModifyWindow(ctx context.Context, fss ...Info) time.Duration

GetModifyWindow calculates the maximum modify window between the given Fses and the Config.ModifyWindow parameter.

func Infof 

func Infof(o interface{}, text string, args ...interface{})

Infof writes info on transfers for this Object or Fs. Use this level for logging transfers, deletions and things which should appear with the -v flag.

LogPrintf produces a log string from the arguments passed in

func Logf 

func Logf(o interface{}, text string, args ...interface{})

Logf writes log output for this Object or Fs. This should be considered to be Notice level logging. It is the default level. By default rclone should not log very much so only use this for important things the user should see. The user can filter these out with the -q flag.

func MatchProvider 

func MatchProvider(providerConfig, provider string) bool

MatchProvider returns true if provider matches the providerConfig string.

The providerConfig string can either be a list of providers to match, or if it starts with "!" it will be a list of providers not to match.

If either providerConfig or provider is blank then it will return true

type ConfigIn 

type ConfigIn struct {
	State  string // State to run
	Result string // Result from previous Option
}

ConfigIn is passed to the Config function for an Fs

The interactive config system for backends is state based. This is so that different frontends to the config can be attached, eg over the API or web page.

Each call to the config system supplies ConfigIn which tells the system what to do. Each will return a ConfigOut which gives a question to ask the user and a state to return to. There is one special question which allows the backends to do OAuth.

The ConfigIn contains a State which the backend should act upon and a Result from the previous question to the user.

If ConfigOut is nil or ConfigOut.State == "" then the process is deemed to have finished. If there is no Option in ConfigOut then the next state will be called immediately. This is wrapped in ConfigGoto and ConfigResult.

Backends should keep no state in memory - if they need to persist things between calls it should be persisted in the config file. Things can also be persisted in the state using the StatePush and StatePop utilities here.

The utilities here are convenience methods for different kinds of questions and responses.

Where the questions ask for a name then this should start with "config_" to show it is an ephemeral config input rather than the actual value stored in the config file. Names beginning with "config_fs_" are reserved for internal use.

State names starting with "*" are reserved for internal use.

Note that in the bin directory there is a python program called "config.py" which shows how this interface should be used.

type RangeOption 

type RangeOption struct {

Note that the End is inclusive, so to fetch 100 bytes you would use RangeOption{Start: 0, End: 99}

If Start is specified but End is not then it will fetch from Start to the end of the file.

If End is specified, but Start is not then it will fetch the last End bytes.

Examples: 

RangeOption{Start: 0, End: 99} - fetch the first 100 bytes
RangeOption{Start: 100, End: 199} - fetch the second 100 bytes
RangeOption{Start: 100, End: -1} - fetch bytes from offset 100 to the end
