Coding
====================

Please be consistent with the existing coding style.

Block style:
```c++
bool Function(char* psz, int n)
{
// Comment summarising what this section of code does
for (int i = 0; i < n; i++)
{
// When something fails, return early
if (!Something())
return false;
...
}

// Success return is usually at the end
return true;
}
```
- ANSI/Allman block style
- 4 space indenting, no tabs
- No extra spaces inside parenthesis; please don't do ( this )
- No space after function names, one space after if, for and while
Various coding styles have been used during the history of the codebase,
and the result is not very consistent. However, we're now trying to converge to
a single style, so please use it in new code. Old code will be converted
gradually.
- Basic rules specified in src/.clang-format. Use a recent clang-format-3.5 to format automatically.
- Braces on new lines for namespaces, classes, functions, methods.
- Braces on the same line for everything else.
- 4 space indentation (no tabs) for every block except namespaces.
- No indentation for public/protected/private or for namespaces.
- No extra spaces inside parenthesis; don't do ( this )
- No space after function names; one space after if, for and while.
- Includes need to be ordered alphabetically, separate own and foreign headers with a new-line (example key.cpp):
```c++
#include "key.h"
@@ -38,31 +26,29 @@ Block style:
class CAlpha;
class CBeta;
```
- When using namespace keyword use the following form:
```c++
namespace Foo {

...
Block style example:
```c++
namespace foo
{
class Class
{
bool Function(char* psz, int n)
{
// Comment summarising what this section of code does
for (int i = 0; i < n; i++) {
// When something fails, return early
if (!Something())
return false;
...
}

} // Foo
// Success return is usually at the end
return true;
}
}
}
```
Variable names begin with the type in lowercase, like nSomeVariable.
Please don't put the first word of the variable name in lowercase like
someVariable.

Common types:

n integer number: short, unsigned short, int, unsigned int, int64, uint64, sometimes char if used as a number
d double, float
f flag
hash uint256
p pointer or array, one p for each level of indirection
psz pointer to null terminated string
str string object
v vector or similar list objects
map map or multimap
set set or multiset
bn CBigNum
