txExiftool

Exiftool protocol and stream endpoint plugin to be used with twisted.

Usage

from twisted.internet import defer, endpoints, protocol, reactor
from txexiftool import ExiftoolProtocol

@defer.inlineCallbacks
def test():
    # Construct an exiftool endpoint. If the tool is installed in a custom
    # location, specify the path to the binary as the first argument. E.g.
    # 'exiftool:/path/to/exiftool'
    ep = endpoints.clientFromString(reactor, 'exiftool')

    # Instantiate the protocol by connecting to the endpoint
    f = protocol.Factory.forProtocol(ExiftoolProtocol)
    p = yield ep.connect(f)

    # Run commands and retrieve results.
    metadata = yield p.execute('-j', '/usr/share/pixmaps/gtkvim.png')
    print metadata

    # Disconnect
    yield p.loseConnection()

    reactor.stop()

reactor.callWhenRunning(test)
reactor.run()
