-Have all your function & method calls automatically logged, in indented outline\r
-form - unlike the stack snapshots in an interactive debugger, it tracks call\r
-structure & stack depths across time!\r
-\r
-It hooks into all function calls that you specify, and logs each time they're\r
-called. I find it especially useful when I don't know what's getting called\r
-when, or need to continuously test for state changes. (by hacking this file)\r
-\r
-Originally inspired from the python cookbook: \r
-http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/198078\r
-\r
-Currently you can\r
- - tag functions or individual methods to be autologged\r
- - tag an entire class's methods to be autologged\r
- - tag an entire module's classes and functions to be autologged\r
-\r
-TODO:\r
- - allow tagging of ALL modules in the program on startup?\r
-\r
-CAVEATS:\r
- - certain classes barf when you logclass() them -- most notably,\r
- SWIG-generated wrappers, and perhaps others.\r
-\r
-USAGE: see examples on the bottom of this file.\r
-\r
-\r
-Viewing tips\r
-============\r
-\r
-If your terminal can't keep up, try xterm or putty, they seem to be highest\r
-performance. xterm is available for all platforms through X11...\r
-\r
-Also try: (RunChandler > log &); tail -f log\r
-\r
-Also, you can "less -R log" afterward and get the colors correct.\r
-\r
-If you have long lines, less -RS kills wrapping, enhancing readability. Also\r
-can chop at formatAllArgs().\r
-\r
-If you want long lines to be chopped realtime, try piping through less::\r
-\r
- RunChandler | less -RS\r
-\r
-but then you have to hit 'space' lots to prevent chandler from freezing.\r
-less's 'F' command is supposed to do this correctly but doesn't work for me.\r
