.. title:: clang-tidy - misc-string-constructor
misc-string-constructor
=======================
Finds string constructors that are suspicious and probably errors.
A common mistake is to swap parameters to the 'fill' string-constructor.
Examples:
.. code-block:: c++
std::string('x', 50) str; // should be std::string(50, 'x')
Calling the string-literal constructor with a length bigger than the literal is
suspicious and adds extra random characters to the string.
Examples:
.. code-block:: c++
std::string("test", 200); // Will include random characters after "test".
Creating an empty string from constructors with parameters is considered
suspicious. The programmer should use the empty constructor instead.
Examples:
.. code-block:: c++
std::string("test", 0); // Creation of an empty string.
