Various coding styles have been used during the history of the codebase,

-a single style, so please use it in new code. Old code will be converted
-gradually and you are encouraged to use the provided
-[clang-format-diff script](/contrib/devtools/README.md#clang-format-diffpy)
-to clean up the patch automatically before submitting a pull request.
+a single style, which is specified below. When writing patches, favor the new
+style over attempting to mimick the surrounding style, except for move-only
+commits.
+
+Do not submit patches solely to modify the style of existing code.
-- Basic rules specified in [src/.clang-format](/src/.clang-format).
+- **Indentation and whitespace rules** as specified in

- 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 `namespace`.
- No extra spaces inside parenthesis; don't do ( this )
- No space after function names; one space after `if`, `for` and `while`.
- - If an `if` only has a single-statement then-clause, it can appear
- on the same line as the if, without braces. In every other case,
- braces are required, and the then and else clauses must appear

+ on the same line as the `if`, without braces. In every other case,
+ braces are required, and the `then` and `else` clauses must appear
correctly indented on a new line.
+
+- **Symbol naming conventions**. These are preferred in new code, but are not
+required when doing so would need changes to significant pieces of existing
+code.
+ - Variable and namespace names are all lowercase, and may use `_` to
+ separate words.
+ - Class member variables have a `m_` prefix.
+ - Global variables have a `g_` prefix.
+ - Constant names are all uppercase, and use `_` to separate words.
+ - Class names, function names and method names are CamelCase. Do not prefix

+- **Miscellaneous**
- `++i` is preferred over `i++`.
