teak-llvm/lldb/examples/python/crashlog.py
Greg Clayton 53b43b0798 Use the "shlex" module to parse the command line that was passed down into 
python so that single and double quotes and other standard shell like argument
parsing happens as expected before passing stuff along to option parsing.

Also handle exceptions so that we don't accidentally exit lldb if an uncaught
exception occurs.

#----------------------------------------------------------------------
# Be sure to add the python path that points to the LLDB shared library.
#
# To use this in the embedded python interpreter using "lldb":
#
# cd /path/containing/crashlog.py
# lldb
# (lldb) script import crashlog
# "crashlog" command installed, type "crashlog --help" for detailed help
# (lldb) crashlog ~/Library/Logs/DiagnosticReports/a.crash
#
# The benefit of running the crashlog command inside lldb in the
# embedded python interpreter is when the command completes, there
# will be a target with all of the files loaded at the locations
# described in the crash log. Only the files that have stack frames
# in the backtrace will be loaded unless the "--load-all" option
# has been specified. This allows users to explore the program in the
# state it was in right at crash time.
#
# On MacOSX csh, tcsh:
# ( setenv PYTHONPATH /path/to/LLDB.framework/Resources/Python ; ./crashlog.py ~/Library/Logs/DiagnosticReports/a.crash )
#
# On MacOSX sh, bash:
# PYTHONPATH=/path/to/LLDB.framework/Resources/Python ./crashlog.py ~/Library/Logs/DiagnosticReports/a.crash
