q is a better way to do print statement debugging.

Type q.Q instead of fmt.Printf and your variables will be printed like this:

• Faster to type
• Pretty-printed vars and expressions
• Easier to see inside structs
• Doesn't go to noisy-ass stdout. It goes to $TMPDIR/q.
• Pretty colors!

import "q"
...
q.Q(a, b, c)

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

git clone https://github.com/ryboe/q "$(go env GOPATH)"/src/q

Put these functions in your shell config. Typing qq or rmqq will then start tailing $TMPDIR/q.

qq() {
    clear

    logpath="$TMPDIR/q"
    if [[ -z "$TMPDIR" ]]; then
        logpath="/tmp/q"
    fi

    if [[ ! -f "$logpath" ]]; then
        echo 'Q LOG' > "$logpath"
    fi

    tail -100f -- "$logpath"
}

rmqq() {
    logpath="$TMPDIR/q"
    if [[ -z "$TMPDIR" ]]; then
        logpath="/tmp/q"
    fi
    if [[ -f "$logpath" ]]; then
        rm "$logpath"
    fi
    qq
}

You also can simply tail -f $TMPDIR/q, but it's highly recommended to use the above commands.

In Go, add a new template with:

• Abbreviation: qq
• Description: Pretty-print to $TMPDIR/q
• Template text: q.Q($END$) // DEBUG
• Applicable in: select the Go scope

Add a new snippet file to the go-mode snippets directory ($HOME/.emacs.d/snippets/go-mode/qq). This should contain:

# -*- mode: snippet -*-
# name: qq
# key: qq
# --
q.Q(${1:...}) // DEBUG

For SirVer/ultisnips, use :UltiSnipsEdit to add the new snippet:

snippet qq "qq"
q.Q(${1:})
${2}
endsnippet

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 :)

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

Yes.
