abseil-string-find-str-contains

Finds s.find(...) == string::npos comparisons (for various string-like types) and suggests replacing with absl::StrContains().

This improves readability and reduces the likelihood of accidentally mixing find() and npos from different string-like types.

By default, "string-like types" includes ::std::basic_string, ::std::basic_string_view, and ::absl::string_view. See the StringLikeClasses option to change this.

std::string s = "...";
if (s.find("Hello World") == std::string::npos) { /* do something */ }

absl::string_view a = "...";
if (absl::string_view::npos != a.find("Hello World")) { /* do something */ }

becomes

std::string s = "...";
if (!absl::StrContains(s, "Hello World")) { /* do something */ }

absl::string_view a = "...";
if (absl::StrContains(a, "Hello World")) { /* do something */ }
