Rails spinoffs - Apr 2007 - dump() javascript function - like PHP's print_r()

I know I''ll be using this one from time to time; thought others might 
like it, too.  The dump() function is similar to PHP''s print_r() and 
will show the contents of an object in a human-readable format.  More 
information:

Use Firebug and call console.dir(xxx,yyy,zzz)

You can also use FireBugLite for IE to do the same.

True, but this may provide the opportunity for those who don''t have 
firebug or firebuglite (for some unknown reason) and the output is nicer 
if you''re alerting the information rather than using the console 
functions of firebug.

To generate such a thing, you could take a look at the cool PHP class
dbug at http://dbug.ospinto.com

Converting this to JS wouldn''t be too onerous.

Is this the sort of thing you are looking for?

Having said that though, your code could easily include FireBugLite.js
and call console.dir(). That way you get a strong script (firebug is
THE debugging script it seems) and can easily add this to your script
loader (I use combine.php from
http://rakaz.nl/item/make_your_pages_load_faster_by_combining_and_compressing_javascript_and_css_files)

If you don''t have server side PHP, making a Perl, Python or ASP
variant shouldn''t be too hard.

What I''m saying is that something like the print_r() command in PHP is
really a poor debugging tool. Debugging shouldn''t be something you
"leave in" on a production site.

But by using firebuglite.js you can add debugging to your client side
code easily and remove it just as easily too.

Wow, that is pretty cool.  It might be more than I personally need for a 
javascript object dumping option, but it is very cool.''''

An other option are tPrototype''s built-in inspect() methods:

 >>> $H({blah:''blech''}).inspect()
"#<Hash:{''blah'': ''blech''}>"

Sure, I understand that.  I''m not indicating that this should be 
something that''s available in production, but only that someone in 
addition to me might one day possibly find it useful when debugging 
something, not that it''s the be-all-end-all of javascript debugging 
capabilities.  I''m a big firebug user and I evangelize it at every 
opportunity, but fact of the matter is that some people don''t use 
firefox and, those who don''t, might not be willing to use firebuglite 
or, prior to this thread, may not have been aware of it.  Thus, a 
function like dump() might come in very handy for them.

I see what you''re saying, but I would feel happier using an
off-the-shelf debugging tool rather than having to go through the
whole design process for a roll-my-own.

firebuglite.js does what it needs to do VERY well.

For full blown FireBug there is a clever extension which allows you to
report PHP variables to a new panel in FireBug - http://firephp.org/.

I think what I''m saying is that if you are prepared to use a third
party library like prototype, then you''ve obviously got your head
screwed on the right way round. There would be little mileage in
re-inventing the wheel when Firebug/FireBugLite does then job.

Sure, you way want a something like dBug, but that is PHP specific.

Also, prototype is not a debugging tool, it is an enabler - debugging
should have happened long before you get to production. And that is
why I like firebug. You can add a single line to your code and all the
debugging info becomes available. Nice and clean and less intrusive
than editing the code to add a ton of debug prints when you may edit
something else.
