nk::builtin::sprintf
Value sprintf(const Value &fmt, Span< const Value > args, std::pmr::memory_resource *mr=nullptr)
Formats data into a character array or string according to format specifier fmt (sprintf(fmt,...
nk::builtin::sscanf
Value sscanf(const std::string &str, const std::string &fmt, std::pmr::memory_resource *mr=nullptr)
Reads formatted data from a string according to format specifier fmt (sscanf(str, fmt)).
nk::builtin::disp
void disp(const Value &v, std::ostream &os=std::cout)
Displays value to the standard output or specified stream (disp(v)).
nk::builtin::fprintf
int fprintf(std::ostream &os, const std::string &fmt, Span< const Value > args, std::pmr::memory_resource *mr=nullptr)
Formats and writes data to an output stream (fprintf(os, fmt, ...)).
nk::builtin::dispFormat
std::string dispFormat(const Value &a)
Formats Value for terminal display via disp.
