This adds an event that is emitted just before GDB presents a prompt to the user. This provides Python code a way to react to whatever changes might have been made by the previous command. For example, in my GUI I use this to track changes to the selected frame and reflect them in the UI. Built and regtested on x86-64 Fedora 23. gdb/ChangeLog 2017-02-14 Tom Tromey <tom@tromey.com> PR python/13598: * python/python.c (gdbpy_before_prompt_hook): Emit before_prompt event. * python/py-evts.c (gdbpy_initialize_py_events): Add before_prompt registry. * python/py-events.h (events_object) <before_prompt>: New field. gdb/doc/ChangeLog 2017-02-14 Tom Tromey <tom@tromey.com> PR python/13598: * python.texi (Events In Python): Document events.before_prompt. gdb/testsuite/ChangeLog 2017-02-14 Tom Tromey <tom@tromey.com> PR python/13598: * gdb.python/py-events.exp: Add before_prompt event tests.
