demangle module

demangle_gnu3(arch, mangled_name, options=None)[source]

demangle_gnu3 demangles a mangled name to a Type object.

Parameters:
  • arch (Architecture) – Architecture for the symbol. Required for pointer and integer sizes.

  • mangled_name (str) – a mangled GNU3 name

  • options (Tuple[bool, BinaryView, None]) – (optional) Whether to simplify demangled names : None falls back to user settings, a BinaryView uses that BinaryView’s settings, or a boolean to set it directly

Returns:

returns tuple of (Type, demangled_name) or (None, mangled_name) on error

Return type:

Tuple

demangle_ms(archOrPlatform: Union[Architecture, Platform], mangled_name: str, options=False)[source]

demangle_ms demangles a mangled Microsoft Visual Studio C++ name to a Type object.

Parameters:
  • archOrPlatform (Union[Architecture, Platform]) – Architecture or Platform for the symbol. Required for pointer/integer sizes and calling conventions.

  • mangled_name (str) – a mangled Microsoft Visual Studio C++ name

  • options (Tuple[bool, BinaryView, None]) – (optional) Whether to simplify demangled names : None falls back to user settings, a BinaryView uses that BinaryView’s settings, or a boolean to set it directly

  • archOrPlatform

Returns:

returns tuple of (Type, demangled_name) or (None, mangled_name) on error

Return type:

Tuple

Example:
>>> demangle_ms(Platform["x86_64"], "?testf@Foobar@@SA?AW4foo@1@W421@@Z")
(<type: public: static enum Foobar::foo __cdecl (enum Foobar::foo)>, ['Foobar', 'testf'])
>>>
get_qualified_name(names)[source]

get_qualified_name gets a qualified name for the provided name list.

Parameters:

names (list(str)) – name list to qualify

Returns:

a qualified name

Return type:

str

Example:
>>> type, name = demangle_ms(Architecture["x86_64"], "?testf@Foobar@@SA?AW4foo@1@W421@@Z")
>>> get_qualified_name(name)
'Foobar::testf'
>>>
simplify_name_to_qualified_name(input_name, simplify=True)[source]

simplify_name_to_qualified_name simplifies a templated C++ name with default arguments and returns a qualified name. This can also tokenize a string to a qualified name with/without simplifying it

Parameters:
  • input_name (Union[str, QualifiedName]) – String or qualified name to be simplified

  • simplify (bool) – (optional) Whether to simplify input string (no effect if given a qualified name; will always simplify)

Returns:

simplified name (or one-element array containing the input if simplifier fails/cannot simplify)

Return type:

QualifiedName

Example:
>>> demangle.simplify_name_to_qualified_name(QualifiedName(["std", "__cxx11", "basic_string<wchar, std::char_traits<wchar>, std::allocator<wchar> >"]), True)
'std::wstring'
>>>
simplify_name_to_string(input_name)[source]

simplify_name_to_string simplifies a templated C++ name with default arguments and returns a string

Parameters:

input_name (Union[str, QualifiedName]) – String or qualified name to be simplified

Returns:

simplified name (or original name if simplifier fails/cannot simplify)

Return type:

str

Example:
>>> demangle.simplify_name_to_string("std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >")
'std::string'
>>>
