QQ improves puts debugging because most Ruby programmers are puts debuggers.

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

• 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!

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

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

Python programmers will recognize this as a less awesome port of the q module by zestyping Ka-Ping Yee (zestyping).

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

Go developers may have seen this q port by y0ssar1an.

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.

gem install qq

Sadly there is already this q gem.

Yes

Your $TMP or $TMPDIR may point somewhere else.

qq --tmpdir

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.
