do_interpolation()

static std::string do_interpolation ( const std::string &  str, const variable_set &  set  )

edit_distance_approx()

std::size_t edit_distance_approx ( std::string_view  str_1, std::string_view  str_2  )

noexcept

Calculate the approximate edit distance of two strings.

Parameters

str_1	First string to compare.
str_2	Second string to compare.

Returns

A score indicating how different the two strings are–the lower the score, the more similar the strings are.

Note

To avoid dynamic allocation, this function limits the number of characters that participate in the comparison.
