var DefaultOpt = Opt{
	MinAge:  fs.DurationOff,
	MaxAge:  fs.DurationOff,
	MinSize: fs.SizeSuffix(-1),
	MaxSize: fs.SizeSuffix(-1),

DefaultOpt is the default config for the filter


func CopyConfig added in v1.55.0

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

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

func GetUseFilter added in v1.57.0

func GetUseFilter(ctx context.Context) bool

GetUseFilter obtains the "use filter" flag from context The flag tells filter-aware backends (Drive) to constrain List using filter

func GlobToRegexp added in v1.58.0

func GlobToRegexp(glob string, ignoreCase bool) (*regexp.Regexp, error)

GlobToRegexp converts an rsync style glob to a regexp

documented in

func ReplaceConfig added in v1.54.0

func ReplaceConfig(ctx context.Context, f *Filter) context.Context

ReplaceConfig replaces the filter config in the ctx with the one passed in and returns a new context with that added to it.

func SetUseFilter added in v1.57.0

func SetUseFilter(ctx context.Context, useFilter bool) context.Context

SetUseFilter returns a context having (re)set the "use filter" flag


type FilesMap

type FilesMap map[string]struct{}

FilesMap describes the map of files to transfer

type Filter

type Filter struct {
	Opt         Opt
	ModTimeFrom time.Time
	ModTimeTo   time.Time
	// contains filtered or unexported fields

Filter describes any filtering in operation

func AddConfig added in v1.54.0

func AddConfig(ctx context.Context) (context.Context, *Filter)

AddConfig returns a mutable config structure based on a shallow copy of that found in ctx and returns a new context with that added to it.

func GetConfig added in v1.54.0

func GetConfig(ctx context.Context) *Filter

GetConfig returns the global or context sensitive config

func NewFilter

func NewFilter(opt *Opt) (f *Filter, err error)

NewFilter parses the command line options and creates a Filter object. If opt is nil, then DefaultOpt will be used

func (*Filter) Add

func (f *Filter) Add(Include bool, glob string) error

Add adds a filter rule with include or exclude status indicated

func (*Filter) AddFile

func (f *Filter) AddFile(file string) error

AddFile adds a single file to the files from list

func (*Filter) AddRule

func (f *Filter) AddRule(rule string) error

AddRule adds a filter rule with include/exclude indicated by the prefix

These are

  • glob
  • glob !

'+' includes the glob, '-' excludes it and '!' resets the filter list

Line comments may be introduced with '#' or ';'

func (*Filter) Clear

func (f *Filter) Clear()

Clear clears all the filter rules

func (*Filter) DirContainsExcludeFile

func (f *Filter) DirContainsExcludeFile(ctx context.Context, fremote fs.Fs, remote string) (bool, error)

DirContainsExcludeFile checks if exclude file is present in a directory. If fs is nil, it works properly if ExcludeFile is an empty string (for testing).

func (*Filter) DumpFilters

func (f *Filter) DumpFilters() string

DumpFilters dumps the filters in textual form, 1 per line

func (*Filter) Files

func (f *Filter) Files() FilesMap

Files returns all the files from the `--files-from` list

It may be nil if the list is empty

func (*Filter) HaveFilesFrom

func (f *Filter) HaveFilesFrom() bool

HaveFilesFrom returns true if --files-from has been supplied

func (*Filter) InActive

func (f *Filter) InActive() bool

InActive returns false if any filters are active

func (*Filter) Include

func (f *Filter) Include(remote string, size int64, modTime time.Time) bool

Include returns whether this object should be included into the sync or not

func (*Filter) IncludeDirectory

func (f *Filter) IncludeDirectory(ctx context.Context, fs fs.Fs) func(string) (bool, error)

IncludeDirectory returns a function which checks whether this directory should be included in the sync or not.

func (*Filter) IncludeObject

func (f *Filter) IncludeObject(ctx context.Context, o fs.Object) bool

IncludeObject returns whether this object should be included into the sync or not. This is a convenience function to avoid calling o.ModTime(), which is an expensive operation.

func (*Filter) IncludeRemote added in v1.56.0

func (f *Filter) IncludeRemote(remote string) bool

IncludeRemote returns whether this remote passes the filter rules.

func (*Filter) ListContainsExcludeFile

func (f *Filter) ListContainsExcludeFile(entries fs.DirEntries) bool

ListContainsExcludeFile checks if exclude file is present in the list.

func (*Filter) MakeListR

func (f *Filter) MakeListR(ctx context.Context, NewObject func(ctx context.Context, remote string) (fs.Object, error)) fs.ListRFn

MakeListR makes function to return all the files set using --files-from

func (*Filter) UsesDirectoryFilters

func (f *Filter) UsesDirectoryFilters() bool

UsesDirectoryFilters returns true if the filter uses directory filters and false if it doesn't.

This is used in deciding whether to walk directories or use ListR

type Opt

type Opt struct {
	DeleteExcluded bool
	FilterRule     []string
	FilterFrom     []string
	ExcludeRule    []string
	ExcludeFrom    []string
	ExcludeFile    string

	MinAge         fs.Duration
	MaxAge         fs.Duration
	MinSize        fs.SizeSuffix
	MaxSize        fs.SizeSuffix
	IgnoreCase     bool

Opt configures the filter
