# QQ

QQ improves puts debugging because most Ruby programmers are
[puts debuggers](https://tenderlovemaking.com/2016/02/05/i-am-a-puts-debuggerer.html).

Type `qq` instead of `pp`, `puts` etc are your variables will be pretty printed
to `q` in your temp directory.

## Why is this better than pp, puts, print?

* Less keystrokes.
* Pretty-printed objects, vars and expressions.
* No searching for redirected `$stderr`, `$stdout`.
* No log levels, locations or filtering to obscure your debugging.
* Pretty colors!

## Usage

```ruby
require 'qq'
# ...
qq(foo, bar, baz)
```

Use the `qq` command installed with the gem to tail the `q` file in your temp
directory.

## Haven't I seen this somewhere before?

### Python
Python programmers will recognize this as a less awesome port of the
[`q` module by zestyping](https://github.com/zestyping/q) Ka-Ping Yee (zestyping).

Zestyping does a great job of explaining `q` in his awesome lightning talk from
PyCon 2013:

### Go
Go developers may have seen [this `q` port by y0ssar1an](https://github.com/y0ssar1an/q).

Even if you don't write Go this port includes notes on shell setup, snippets
and autocomplete helpers for editors so it's worth a look if you use `q` in
any language.

## Install

```sh
gem install qq
```

## FAQ

### Why `qq` and not `q`?
Sadly there is already [this `q` gem](https://rubygems.org/gems/q).

### Is `qq` thread safe?
Yes

### Why is there no `q` in `/tmp/q`?
Your `$TMP` or `$TMPDIR` may point somewhere else.
```sh
qq --tmpdir
```

## Known issues

Calling `qq` twice on the one line.
`Thread::Backtrace::Location` doesn't list a column for the caller.
Use multiple arguments to the one `qq` call instead.
