# humanlog
Read logs from `stdin` and prints them back to `stdout`, but prettier.
# Using it
[Grab a release](https://github.com/aybabtme/humanlog/releases) or :
## With Go installed
```bash
$ go get -u github.com/aybabtme/humanlog/...
```
## On linux
```bash
wget -qO- https://github.com/aybabtme/humanlog/releases/download/0.4.0/humanlog_Linux_x86_64.tar.gz | tar xvz
```
## On OS X
```bash
brew tap aybabtme/homebrew-tap
brew install humanlog
```
# Example
If you emit logs in JSON or in [`logfmt`](https://brandur.org/logfmt), you will enjoy pretty logs when those
entries are encountered by `humanlog`. Unrecognized lines are left unchanged.
```
$ humanlog < /var/log/logfile.log
```
![2__fish___users_antoine_gocode_src_github_com_aybabtme_humanlog__fish_](https://cloud.githubusercontent.com/assets/1189716/4328545/f2330bb4-3f86-11e4-8242-4f49f6ae9efc.png)
# Contributing
How to help:
* __support more log formats__: by submitting `human.Handler` implementations.
* __live querying__: add support for filtering in log output in real time.
* __charting__: some key-values have semantics that could be charted in real time. For
instance, durations, frequency of numeric values, etc. See the [l2met][] project.
# Usage
```
NAME:
humanlog - reads structured logs from stdin, makes them pretty on stdout!

# logfmt
Package logfmt implements utilities to marshal and unmarshal data in the [logfmt
format](https://brandur.org/logfmt). It provides an API similar to
[encoding/json](http://golang.org/pkg/encoding/json/) and
[encoding/xml](http://golang.org/pkg/encoding/xml/).
The logfmt format was first documented by Brandur Leach in [this
article](https://brandur.org/logfmt). The format has not been formally
standardized. The most authoritative public specification to date has been the
documentation of a Go Language [package](http://godoc.org/github.com/kr/logfmt)
written by Blake Mizerany and Keith Rarick.
## Goals
This project attempts to conform as closely as possible to the prior art, while
also removing ambiguity where necessary to provide well behaved encoder and
decoder implementations.
## Non-goals
This project does not attempt to formally standardize the logfmt format. In the
event that logfmt is standardized this project would take conforming to the
standard as a goal.
## Versioning
Package logfmt publishes releases via [semver](http://semver.org/) compatible Git tags prefixed with a single 'v'.
