Zero
2+
====
3+
4+
Zero is a bunch of single-files libraries for C/C++.
5+
6+
It is written in C89 at the exception of a couple of features borrowed from C99,
7+
namely fixed-width integer types and variadic macros.
8+
9+
10+
## Features
11+
12+
* mostly C89-compliant
13+
* headers don't include anything by default <sup>[1]</sup>
14+
* implementations are included upon defining the `ZR_IMPLEMENTATION` macro
15+
* each library is a standalone single file to ease integration into projects
16+
* simple
17+
18+
1. The only exception being `<stdarg.h>` for headers defining functions with a
19+
`va_list` object as parameter.
20+
21+
22+
## Libraries
23+
24+
25+
| library | description | latest version |
26+
|---------|-------------|----------------|
27+
**[allocator.h](include/zero/allocator.h)** | Aligned and non-aligned wrappers of malloc/realloc/free | 0.1.0
28+
**[logger.h](include/zero/logger.h)** | Simple logger with different log levels and colouring | 0.1.0
29+
30+
31+
## FAQ
32+
33+
### Why defining custom fixed-width integer types and even `size_t`?
34+
35+
Because most projects target common platforms (Windows, Linux, macOS), thus
36+
using either the ILP32, LP64, or LLP64 data models, which all guarantee the
37+
`char` type to be 8 bits, `short` to be 16 bits, `int` to be 32 bits, and
38+
`long long` to be 64 bits. If such types can be accurately defined in a few
39+
lines for most of the projects, then why including a standard header that
40+
resolves to _thousands_ of lines of code with its dependencies? For the exotic
41+
platforms, the macro `ZR_USE_STD_FIXED_TYPES` can be defined, or each type can
42+
be overrided individually.
43+
44+
The same applies to redefining `size_t`—on almost all platforms the size of
45+
`size_t` equals the targetted architecture, that is either 32 or 64 bits. Here
46+
again, if that's not enough then it's still possible to define
47+
the macro `ZR_USE_STD_BASIC_TYPES`.
48+
49+
Note that these custom types are only used for the public interface defined in
50+
the headers, to avoid cluttering project headers including them. But the
51+
implementation sections make free use of standard headers as needed
52+
(including standard fixed-width integer types and `size_t`).
