| ``function.name-without-args`` | The name of the current function without arguments and values (used to include a function name in-line in the ``disassembly-format``) |
| ``function.basename`` | The basename of the current function depending on the frame's language. E.g., for C++ the basename for ``void ns::foo<float>::bar<int>(int) const`` is ``bar``. |

When debug-info is available, will apply data-formatters to each argument and include it's name if available. Otherwise prints the type of each argument according to the mangling. E.g., for C++ the |

The function names displayed in backtraces/``frame info``/``thread info`` are the demangled names of functions. On some platforms (like ones using Itanium the mangling scheme), LLDB supports decomposing these names into fine-grained components. These are currently:

-
* ``${function.return-left}``
325
-
* ``${function.scope}``
326
-
* ``${function.basename}``
327
-
* ``${function.template-arguments}``
328
-
* ``${function.formatted-arguments}``
329
-
* ``${function.qualifiers}``
330
-
* ``${function.return-right}``

Each language plugin decides how to handle these variables. For C++, LLDB uses these variables to dictate how function names are formatted. This can be customized using the ``plugin.cplusplus.display.function-name-format`` LLDB setting.
