PHP ERB

Patrick May

1/17/2005 9:40:00 PM

Hello,

One of the nice things about php is that the '<?>' keys are close to
each other. One of the annoying things about asp and jsp is that '<>'
use one hand, and '%' uses another.

Attached is a patch to erb.rb that allows ?'s as well as %'s in erb
templates:

<% puts "this works" %>
<? puts "as does this" ?>

Let me know if there is anything I can do to make this a better patch.
If you want to play with this, you can grab the patched version of erb
from narf:

http://svn.narf-lib.org/svn/narf/trunk/lib/we...

I renamed the constant to PHPRB, so as not to collide with the standard
lib.

Cheers,

Patrick

+1 in concept, because XML standards suggest it this way, too. However,
<?ruby is better, following the XML processing-instructions spec.

Hello,

I've had some trouble sending the patch over. It is available here:

http://www.narf-lib.org/php...

Cheers,

or just, <?r ?>

(The PHP people say not to use shorttags (<?= $var ?>) too, there was
a zend contest here the 2nd place guy got put down to 6th for that!
And the best prizes were in the top 5 :p )

<?rb ?> gets my vote

Why bother? I don't think something like

<a href="foo/?baz=<?ruby print xyz.poo(42) ?>">

is valid XML either.

That's because you're using the wrong keyboard. Switch to dvorak
layout. ;)

Its even easier than <?, because you're not using your pinky to hit one
of the keys.

(No, really this kinda stuff is useful. :)

+1 for <?r (which IIRC is Nitro's way of doing things :)

Btw, this is EXACTLY what Nitro uses:

<?r if user.role("admin") ?>
....
<?r end ?>

or even

<?ruby .... ?>

or even
<ruby>...</ruby>

but,

<a href="foo/?baz=#{xyz.poo(42)}">...</a>

<a href="foo/?baz=23" <?ruby if xyz.poo(42) ?> target="moep"
<?ruby else ?> title="Example" <?ruby end ?>>
