[arm/master] Dropping remaining addfstr usage
by atagar＠torproject.org 17 Jun '11

commit 6144d50da64fe94bf8ab30c30f5044453cefde01 Author: Damian Johnson <atagar(a)torproject.org> Date: Thu Jun 16 10:11:50 2011 -0700 Dropping remaining addfstr usage Long ago, in the dawn of arm, I added a helper function "addfstr" that allowed for adding strings with formatting tags similar to html. All usage of it with arbitrary input was dropped due to the possability of tag injection screwing up the display, and this change drops its last remaining usage. This hurts the code's readability a bit and at I'd like to figure out a nicer, general purpose pattern for multi-format line rendering but tags aren't the solution. Back to the drawing board...

This library handles sending commands, parsing responses, and delivering events to and from the control port. The basic usage is to create a socket, wrap that in a TorCtl.Connection, and then add an EventHandler -to that connection. A simple example with a DebugEventHandler (that just -echoes the events back to stdout) is present in run_example(). +to that connection. For a simple example that prints our BW events (events +that provide the amount of traffic going over tor) see 'example.py'.
