__doc__='''Command-line Bobo
Usage
bobo [options] module_path [path_info]
where:
module_path -- is a full path to a published module
path_info -- Is the information after the module name that would
normally be specified in a GET URL, including a query string.
Description
The command-line interface to Bobo provides a handy way to test,
debug, and profile Bobo without a web server.
Options
-u username:password -- Supply HTTP authorization information
-e name=value -- Supply environment variables. Use a
seperate -e option for each variable
specified.
-p profiler_data_file -- Run under profiler control,
generating the profiler
data file, profiler_data_file.
-t -- Compute the time required to
complete a request, in
milliseconds.
-r n -- Specify a repeat count for timing or
profiling.
-d -- Run in debug mode. With this
option, bobo will run under Python
debugger control. Two useful
breakpoints are set. The first is
at the beginning of the module
publishing code. Steping through
this code shows how bobo finds
objects and obtains certain
meta-data. The second breakpoint is
at the point just before the
published object is called. To jump
to the second breakpoint, you must
enter 's' followed by a carriage
return to step into the module, then
enter a 'c' followed by a carriage
return to jump to the first
breakpoint and then another 'c'
followed by a carriage return to
jump to the point where the object
is called. Finally, enter 's'
followed a carriage return.
-s Don\'t generate any output
Examples
For example, to debug a published object (such as a method), spam,
the following might be entered::
bobo -d /prj/lib/python/mymod container/spam
