Pattern

Description#

If some files should be or not be synchronized to (or from) other devices, configure the corresponding SyncFilePattern/IgnoreFilePattern. All patterns are relative to the folder root (The folder you select while get into DevMode).

Caution

The priority of the IgnoreFilePattern is higher than SyncFilePattern, so if your pattern both covered the same file, the file will be ignored.

Patterns syntax#

Regular file names match themselves, i.e. the pattern foo matches the files foo, subdir/foo as well as any directory named foo. Spaces are treated as regular characters, except for leading and trailing spaces, which are automatically trimmed.
Asterisk (*) matches zero or more characters in a filename, but does not match the directory separator. te*ne matches telephone, subdir/telephone but not tele/phone.
Double asterisk (**) matches as above, but also directory separators. te**ne matches telephone, subdir/telephone and tele/sub/dir/phone.
Question mark (?) matches a single character that is not the directory separator. te??st matches tebest but not teb/st or test.
Square brackets ([]) denote a character range: [a-z] matches any lower case character.
Curly brackets ({}) denote a set of comma separated alternatives: {banana,pineapple} matches either banana or pineapple.
Backslash (\) “escapes” a special character so that it loses its special meaning. For example, \{banana\} matches {banana} exactly and does not denote a set of alternatives as above. Escaped characters are not supported on Windows.
A pattern beginning with / or ./ matches in the root of the folder only. /foo or ./foo matches foo but not subdir/foo.
A pattern beginning with a (?i) prefix enables case-insensitive pattern matching. (?i)test matches test, TEST and tEsT. The (?i) prefix can be combined with other patterns, for example the pattern (?i)picture*.png indicates that Picture1.PNG should be synchronized. On Mac OS and Windows, patterns are always case-insensitive.

Note

Prefixes can be specified in any order (e.g. “(?i){foo,bar}/*/bar”), but cannot be in a single pair of parentheses (not "{foo,(?i),bar}/*/bar").

Example#

Given a directory layout:

.DS_Store
foo
foofoo
bar/
    baz
    quux
    quuz
bar2/
    baz
    frobble
My Pictures/
    Img15.PNG
nocalhost/
    hello
    test/
    team/

and with following config:

SyncFilePattern:
  - frobble
  - quuz
  - ./nocalhost
  
IgnoreFilePattern:
  - foo
  - *2
  - qu*
  - (?i)my pictures
  - nocalhost/t**

The priority of the IgnoreFilePattern is higher than SyncFilePattern and the end result becomes:

foo           # ignored, matches IgnoreFilePattern "foo"
foofoo        # synced, does not match IgnoreFilePattern "foo", but would match "foo*" or "*foo" 
bar/          # synced, no such config, so synced
    baz       # synced, no such config, so synced
    quux      # ignored, matches IgnoreFilePattern "qu*"
    quuz      # ignored, though specify the SyncFilePattern "quuz",but matches higher level IgnoreFilePattern "qu*"
bar2/         # ignored, matches IgnoreFilePattern "*2"
    baz       # ignored, due to dir parent being ignored
    frobble   # ignored, due to dir parent being ignored
My Pictures/  # ignored, matched IgnoreFilePattern case insensitive "(?i)my pictures" pattern
    Img15.PNG # ignored, due to parent being ignored
nocalhost/    # synced, no such config, so synced
    hello     # synced, no such config, so synced
    test/     # ignored, matches IgnoreFilePattern "nocalhost/t**"
    team/     # ignored, matches IgnoreFilePattern "nocalhost/t**"
