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.
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
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 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.
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
gem install qqFAQ
Why qq and not q?
Sadly there is already this q gem.
Is qq thread safe?
Yes
Why is there no q in /tmp/q?
Your $TMP or $TMPDIR may point somewhere else.
qq --tmpdirKnown 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.
