d

d is a better way to do print statement debugging.

Type d.D instead of fmt.Printf and your variables will be printed like this:

Why is this better than `fmt.Printf`?

Faster to type
Pretty-printed vars and expressions
Easier to see inside structs
Pretty colors!

d is fork of https://github.com/y0ssar1an/q with some differences:

Do not include vendor into repository
Changed default behaviour - for me is more comfortable to log on stdout or have possibility to change file
Settings for removing colors

Basic Usage

import "github.com/marusama/d"
...
d.D(a, b, c)

// Alternatively, use the . import and you can omit the package name.
// d only exports the D function.
import . "github.com/marusama/d"
...
D(a, b, c)

For best results, dedicate a terminal to tailing $TMPDIR/d while you work.

Install

go get -u github.com/marusama/d

vim/Emacs

TBD Send me a PR, please :)

Haven't I seen this somewhere before?

Python programmers will recognize this as a Golang port of the q module by zestyping.

Ping does a great job of explaining q in his awesome lightning talk from PyCon 2013. Watch it! It's funny :)

FAQ

Why `d.D`?

It's quick to type and unlikely to cause naming collisions.
