[![Build Status](https://travis-ci.org/Akagi201/lwlog.svg?branch=master)](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

```
