Parser for standard FTP file listings

This is the evil required to match:

   -rw-r--r--   1 root     other        531 Jan 29 03:26 README

If you need different evil for a wacky FTP server, you can override either fileLinePattern or parseDirectoryLine().

It populates the instance attribute self.files, which is a list containing dicts with the following keys (examples from the above line):

  • filetype: e.g. 'd' for directories, or '-' for an ordinary file
  • perms: e.g. 'rw-r--r--'
  • nlinks: e.g. 1
  • owner: e.g. 'root'
  • group: e.g. 'other'
  • size: e.g. 531
  • date: e.g. 'Jan 29 03:26'
  • filename: e.g. 'README'
  • linktarget: e.g. 'some/file'

Note that the 'date' value will be formatted differently depending on the date. Check http://cr.yp.to/ftp.html if you really want to try to parse it.

It also matches the following:

   -rw-r--r--   1 root     other        531 Jan 29 03:26 I HAVE\ SPACE
      - filename:   e.g. 'I HAVE SPACE'

   -rw-r--r--   1 root     other        531 Jan 29 03:26 LINK -> TARGET
      - filename:   e.g. 'LINK'
      - linktarget: e.g. 'TARGET'

   -rw-r--r--   1 root     other        531 Jan 29 03:26 N S -> L S
      - filename:   e.g. 'N S'
      - linktarget: e.g. 'L S'

def lineReceived(self, line): (source)

Override this for when each line is received.

ParameterslineThe line which was received with the delimiter removed. (type: bytes)
def parseDirectoryLine(self, line): (source)

Return a dictionary of fields, or None if line cannot be parsed.

Returnsdict
def addFile(self, info): (source)

Append file information dictionary to the list of known files.

Subclasses can override or extend this method to handle file information differently without affecting the parsing of data from the server.

Parametersinfodictionary containing the parsed representation of the file information (type: dict)
def unknownLine(self, line): (source)

Deal with received lines which could not be parsed as file information.

Subclasses can override this to perform any special processing needed.
