1.. title:: clang-tidy - abseil-redundant-strcat-calls 2 3abseil-redundant-strcat-calls 4============================= 5 6Suggests removal of unnecessary calls to ``absl::StrCat`` when the result is 7being passed to another call to ``absl::StrCat`` or ``absl::StrAppend``. 8 9The extra calls cause unnecessary temporary strings to be constructed. Removing 10them makes the code smaller and faster. 11 12Examples: 13 14.. code-block:: c++ 15 16 std::string s = absl::StrCat("A", absl::StrCat("B", absl::StrCat("C", "D"))); 17 //before 18 19 std::string s = absl::StrCat("A", "B", "C", "D"); 20 //after 21 22 absl::StrAppend(&s, absl::StrCat("E", "F", "G")); 23 //before 24 25 absl::StrAppend(&s, "E", "F", "G"); 26 //after 27
