Function split_source_prefixes

src/backward.h:687–701

Split a string on the platform's PATH delimiter. Example: if delimiter is ":" then: "" --> [] ":" --> ["",""] "::" --> ["","",""] "/a/b/c" --> ["/a/b/c"] "/a/b/c:/d/e/f" --> ["/a/b/c","/d/e/f"] etc.

//   "/a/b/c:/d/e/f" --> ["/a/b/c","/d/e/f"]
//   etc.
inline std::vector<std::string> split_source_prefixes(const std::string& s)
{
    std::vector<std::string> out;
    size_t last = 0;
    size_t next = 0;
    size_t delimiter_size = sizeof(kBackwardPathDelimiter) - 1;
    while ((next = s.find(kBackwardPathDelimiter, last)) != std::string::npos) {
        out.push_back(s.substr(last, next - last));
        last = next + delimiter_size;
    }
    if (last <= s.length()) {
        out.push_back(s.substr(last));
    }
    return out;
