# 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:
