char * stringify~for_int (int x);
char * stringify~for_char (char c);

// The compiler can infer the suffix to use
stringify (1); // Same as stringify~for_int (1)
char * (*ptr)(int x) = stringify~for_int (1); // It can be given explicitly to get an exact function

// Very silly code but it actually works.

This is my little Christmas-break experiment trying to (among other things) reduce the amount of generated code for containers.

THIS CODE WILL CONTAIN BUGS AND IS ONLY PRESENTED AS AN EXAMPLE.

The C++ STL is still an undesirable library for many reasons I have extolled in the past. But it's also a good library. Demons lie in this here debate and I have no interest in revisiting it right now.

The goals that I have achieved with this approach are:

NocturnDragon

#include <cstdio>

#define with(a) if(a ; true)

struct ExampleScopeGuard
{
    ExampleScopeGuard () : foo(5)
    { 
        printf("ACQUIRE\n");
    }

struct Data
{
  Data()
  {
  }
  
  ~Data()
  {
  }

Jinja compiled templates module loader

This code is part of a Jinja CMS for Google App Engine Python 2.7 and NDB datastore

A Jinja enviroment is created for every CMS site: site_key_id = 'example

The modules are created using compiler.py The resulting code objects are stored in the dadastore using Kind Runtimes and a BlobProperty

The modules can also be saved / downloaded as .pyc in a zip archive: -compiled-templates.zip
