Pretty Printing for Go
|
||
|
======================

||
|
Have you ever wanted to get a pretty-printed version of a Go data structure,
|
||
|
complete with indentation? I have found this especially useful in unit tests
|
||
|
and in debugging my code, and thus godebug was born!

Quick Examples
|
||
|
--------------
|
||
|
|
||
|
By default, pretty will write out a very compact representation of a data structure.
|
||
|
From the [Print example][printex]:
|
||
|
|
||
|
```
|
||
|
{Name: "Spaceship Heart of Gold",
|
||
|
Crew: {Arthur Dent: "Along for the Ride",
|
||
|
Ford Prefect: "A Hoopy Frood",
|
||
|
Trillian: "Human",
|
||
|
Zaphod Beeblebrox: "Galactic President"},
|
||
|
Androids: 1,
|
||
|
Stolen: true}
|
||
|
```
|
||
|
|
||
|
It can also produce a much more verbose, one-item-per-line representation suitable for
|
||
|
[computing diffs][diffex]. See the documentation for more examples and customization.

Installation
|

|
||
|
|
||
|
These packages are available via `go get`:
|
||
|
|
||
|
```bash
|
||
|
$ go get -u github.com/kylelemons/godebug/{pretty,diff}
|
||

Other Packages
|
||
|
--------------
|
||
|
|
||
|
If `godebug/pretty` is not granular enough, I highly recommend
|
||
|
checking out [go-spew][spew].
