lwlog
=====
[](https://travis-ci.org/Akagi201/lwlog)
A header only, colorful, leveled, macro implemented logging lib for C.
```C
lwlog_emerg("This a emerge log.");
lwlog_alert("This a alert log.");
lwlog_crit("This a crit log.");
lwlog_err("This a err log.");
lwlog_warning("This a warning log.");
lwlog_notice("This a notice log.");
lwlog_info("This a info log.");
lwlog_debug("This a debug log.");
```
## Features
* Only one header is needed.
* Colorful output to console.
* `errno` support.
* Simple APIs similar to printf().
* Support different logging levels.
* Zero performance overhead when logging is disabled.
* Customizable module name. [TODO]
* Transparent logging to file/console/network/syslog. [Maybe]
## Install
`clib install Akagi201/lwlog`
## Macro controls
* log level control
* color control
```C
#define LOG_COLOR (1) // 0: off, 1: on, default: 1
#define LOG_LEVEL (7) // -1: off, 0~7: different log levels, default: 7
#include "lwlog.h"
```
## Build & Test
```C
$ gcc test.c
$ ./a.out
```
