  18 # parselog.py, written and contributed by Kevin Marks
  19 #
  20 # Requires OS X 10.3 Panther or later, for Python and Core Graphics Python APIs
  21 # Invoke from the command line with "parselog.py fname" where fname is a log file made by mDNSNetMonitor
  22 #
  23 # Caveats:
  24 # It expects plain ASCII, and doesn't handle spaces in record names very well right now
  25 # There's a procedure you can follow to 'sanitize' an mDNSNetMonitor log file to make it more paletable to parselog.py:
  26 # 1. Run mDNSNetMonitor in a terminal window.
  27 #    When you have enough traffic, type Ctrl-C and save the content of the terminal window to disk.
  28 #    Alternatively, you can use "mDNSNetMonitor > logfile" to write the text directly to a file.
  29 #    You now have a UTF-8 text file.
  30 # 2. Open the UTF-8 text file using BBEdit or some other text editor.
  31 #    (These instructions are for BBEdit, which I highly recommend you use when doing this.)
  32 # 3. Make sure BBEdit correctly interprets the file as UTF-8.
  33 #    Either set your "Text Files Opening" preference to "UTF-8 no BOM", and drop the file onto BBEdit,
  34 #    or manually open the File using "File -> Open" and make sure the "Read As" setting is set to "UTF-8 no BOM"
  35 #    Check in the document pulldown menu in the window toolbar to make sure that it says "Encoding: UTF-8 no BOM"
  36 # 4. Use "Tools -> Convert to ASCII" to replace all special characters with their seven-bit ascii equivalents.
  37 #    (e.g. curly quotes are converted to straight quotes)
  38 # 5. Do a grep search and replace. (Cmd-F; make sure Grep checkbox is turned on.)
  39 #    Enter this search text     : ^(.................\(................\S*) (.* -> .*)$
  40 #    Enter this replacement text: \1-\2
  41 #    Click "Replace All"
  42 #    Press Cmd-Opt-= repeatedly until there are no more instances to be replaced.
  43 #    You now have text file with all spaces in names changed to hyphens
  44 # 6. Save the new file. You can save it as "UTF-8 no BOM", or as "Mac Roman". It really doesn't matter which --
  45 #    the file now contains only seven-bit ascii, so it's all the same no matter how you save it.
  46 # 7. Run "parselog.py fname"
  47 # 8. Open the resulting fname.pdf file with a PDF viewer like Preview on OS X
  48 #

  54 # Filled green  circle: Normal answer             Hollow green  circle: Goodbye message (record going away)
