LLDB script to summarize Qt types in Xcode.
import lldb
def __lldb_init_module(debugger, internal_dict):
debugger.HandleCommand('type summary add QString -F lldb_qt.QString_summary')
debugger.HandleCommand('type summary add QUuid -F lldb_qt.QUuid_summary')
print 'lldb_qt.py has been loaded and is ready for use.'
def QString_summary(value, internal_dict):
name = value.GetName()
deref = '->' if value.TypeIsPointerType() else '.'
return value.frame.EvaluateExpression(name + deref + 'toStdString()').GetSummary()
def QUuid_summary(value, internal_dict):
name = value.GetName()
deref = '->' if value.TypeIsPointerType() else '.'
return value.frame.EvaluateExpression(name + deref + 'toString().toStdString()').GetSummary()

Good script, it still works 10 years after!
Just put the print argument in brackets, and wanted install it at Xcode startup, put the import command in a ~/.lldbinit-Xcode script file.
Thanks!
