Python summary strings:
- you can use a Python script to write a summary string for data-types, in one of
three ways:
-P option and typing the script a line at a time
-s option and passing a one-line Python script
-F option and passing the name of a Python function
these options all work for the "type summary add" command
your Python code (if provided through -P or -s) is wrapped in a function
that accepts two parameters: valobj (a ValueObject) and dict (an LLDB
internal dictionary object). if you use -F and give a function name,
you're expected to define the function on your own and with the right
prototype. your function, however defined, must return a Python string
- test case for the Python summary feature
- a few quirks:
Python summaries cannot have names, and cannot use regex as type names
both issues will be fixed ASAP
major redesign of type summary code:
- type summary working with strings and type summary working with Python code
are two classes, with a common base class SummaryFormat
- SummaryFormat classes now are able to actively format objects rather than
just aggregating data
- cleaner code to print descriptions for summaries
the public API now exports a method to easily navigate a ValueObject hierarchy
New InputReaderEZ and PriorityPointerPair classes
Several minor fixes and improvements
