The str () function, called on a gdb.Value instance, produces a string representation similar to what can be achieved with the print command, but it doesn't allow to specify additional formatting settings, for instance disabling pretty printers. This patch introduces a new format_string () method to gdb.Value which allows specifying more formatting options, thus giving access to more features provided by the internal C function common_val_print (). gdb/ChangeLog: 2019-04-01 Marco Barisione <mbarisione@undo.io> Add gdb.Value.format_string (). * python/py-value.c (copy_py_bool_obj): (valpy_format_string): Add gdb.Value.format_string (). * NEWS: Document the addition of gdb.Value.format_string (). gdb/doc/ChangeLog: 2019-04-01 Marco Barisione <mbarisione@undo.io> * python.texi (Values From Inferior): Document gdb.Value.format_string (). gdb/testsuite/ChangeLog: 2019-04-01 Marco Barisione <mbarisione@undo.io> Test gdb.Value.format_string (). * gdb.python/py-format-string.exp: New test. * gdb.python/py-format-string.c: New file. * gdb.python/py-format-string.py: New file.
