Common
------
* Add your name to [COPYING](/COPYING).
* **Don't** add your name to `AUTHORS` - it's for maintainers.
* Add copyright notice in the beginning of changed files except the headers.
* If you change the behavior (even just fix a bug) of **libkernaux** (stable) or
[libc](/libc), add a record to [ChangeLog](/ChangeLog).
C language
----------
* Name regular functions (*not methods*) and variables in lower snake case
(example: `foo_bar`).
* Name macros in upper snake case (example: `FOO_BAR`).
* Name types (*structures, unions, enumerations and type definitions*) in Pascal
case (example: `FooBar`).
* Name nested types in Pascal case and with the prefix of the surrounding type
in Pascal case, separate type names with underscores (example:
`FooBar_CarCdr`).
* Name methods (*functions that belong to a specific type*) in lower snake case
and with the prefix of the type name in Pascal case (example:
`FooBar_car_cdr`).
* Name public (*defined in the headers and exported as symbols*) regular
functions (*not methods*) and variables with the prefix `kernaux_` (example:
`kernaux_foo_bar`).
* Name public (*defined in the headers*) macros with the prefix `KERNAUX_`
(example: `KERNAUX_FOO_BAR`).
* Name public (*defined in the headers*) types with the prefix `KernAux_`
(example: `KernAux_FooBar`).
* Name public (*defined in the headers*) with the prefix `KernAux_` and with the
prefix of the surrounding type, separate type names with underscore (example:
`KernAux_FooBar_CarCdr`).
* Name public (*defined in the headers*) methods with the prefix `KernAux_` and
with the prefix of the type name (example: `KernAux_FooBar_car_cdr`).
* Create `typedef`s with the names of related `struct`s. Use this name with a
prefix `struct` to declare the data itself, withoth the prefix to declare
a pointer or an array:
```c
typedef struct FooBar { int car; } *FooBar;
static struct FooBar FooBar_create();
static void FooBar FooBar_init(FooBar foobar);
static void FooBar_do_something(FooBar foobar);
// Initialize:
struct FooBar foobar = FooBar_create();
// or
struct FooBar foobar;
FooBar_init(&foobar);
// Use:
FooBar foobar_ptr = &foobar;
FooBar_do_something(&foobar);
```
```c
typedef struct FooBar { int car; } FooBar[1];
static struct FooBar FooBar_create();
static void FooBar FooBar_init(FooBar foobar);
static void FooBar_do_something(FooBar foobar);
// Initialize:
FooBar foobar = { FooBar_create() };
// or
FooBar foobar;
FooBar_init(foobar);
// Use:
FooBar_do_something(foobar);
```
