Function Documentation

◆ 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 

Calculate the approximate edit distance of two strings.

str_1First string to compare.
str_2Second string to compare.
A score indicating how different the two strings are–the lower the score, the more similar the strings are.
To avoid dynamic allocation, this function limits the number of characters that participate in the comparison.
