# 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
|
|
```

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.
