StringBuilder

Create large string easily and optimally

Usage

With default allocator (malloc/free)

#include "StringBuilder.h"

StringBuilder oStrBuilder;
oStrBuilder += "Hello";
oStrBuilder += ' ';
oStrBuilder += "World";
oStrBuilder += '!';

char* pString = oStrBuilder.Export();
printf("%s", pString);
free(pString);

Result output:

Hello World!

With custom allocator

#include "StringBuilder.h"

void* mymalloc(size_t size)
{
  ...
}

void myfree(void* pData)
{
  ...
}

StringBuilder oStrBuilder(mymalloc, myfree);
oStrBuilder += "Hello";
oStrBuilder += ' ';
oStrBuilder += "World";
oStrBuilder += '!';

char* pString = oStrBuilder.Export();
printf("%s", pString);
myfree(pString);

Build string with numeric values

#include "StringBuilder.h"
#include "StringBuilderExtension.h"

StringBuilder oStrBuilder;

oStrBuilder += "int: ";
oStrBuilder += (int)-123456;
oStrBuilder += '\n';

oStrBuilder += "unsigned int: ";
oStrBuilder += (unsigned int)123456;
oStrBuilder += '\n';

oStrBuilder += "long: ";
oStrBuilder += (long)-1234567890123;
oStrBuilder += '\n';

oStrBuilder += "unsigned long: ";
oStrBuilder += (unsigned long)1234567890123;
oStrBuilder += '\n';

oStrBuilder += "float: ";
oStrBuilder += 3.1415926535897932384626433832795028841971f;
oStrBuilder += '\n';

oStrBuilder += "double: ";
oStrBuilder += 3.1415926535897932384626433832795028841971;
oStrBuilder += '\n';

char* pString = oStrBuilder.Export();
printf("%s", pString);
free(pString);

Result output:

int: -123456

unsigned int: 123456

long: -1912276171

unsigned long: 1912276171

float: 3.141593

double: 3.141593

float and double seams the same because the extension use printf with %f for both.
