Using the built-in str() function, which transforms numerical values-including integers-to their string representations, is one popular method. To retrieve the matching string, just supply the integer variable as an input to str(). An alternative approach is to use string formatting techniques ...
using str = sz::string; str("a:b").front(1) == "a"; // no checks, unlike `substr` str("a:b").front(2) == "2"; // take first 2 characters str("a:b").back(-1) == "b"; // accepting negative indices str("a:b").back(-2) == ":b"; // similar to Python's ...
of a string, except for some numerical values. Strings, as we know from many other programming languages, have to be delimited in some way; if that is not possible for some reason, they must be brought into a form of representation that is least likely to interfere with the actual code....
It's not realistic to expect the average developer to remember the 14 overloads of std::string::replace.using str = std::string; assert(str("hello world").substr(6) == "world"); assert(str("hello world").substr(6, 100) == "world"); // 106 is beyond the length of the ...

First, we’ll need a data type for type-indexed de Bruijn indices. A value of type Idx γα is a variable with type α in the context γ (represented as a type-level list of types). For example, Idx [Int,Bool,Int] Int would represent a variable of type Int (and hence must ...

strings is provided by Python's configuration() strategy, an underlying capability. You can control how values in placeholders within a string are displayed. The format() method's straightforward but effective syntax uses curly braces () as placeholders that can be replaced with values or ...
