Added Capability to format DateInterval via twig date filter
hi,
i was wondering why twig couldn't format my DateInterval and added it.
Either this is ok for you or we should add something similar for DateInterval because it uses a little bit different syntax to format its string (e.g. prepend with "%")
Cheers Phil
From the PHP CHANGELOG:
The flag ENT_SUBSTITUTE makes invalid multibyte sequences be replaced by
U+FFFD (UTF-8) or &#FFFD; by htmlspecialchars and htmlentities. It is an
alternative to the default behavior, which just returns an empty string and to
ENT_IGNORE, which is a security risk. The behavior follows the recommendations
of Unicode Technical Report #36.
For example we check if a template and use exception to redirect to a default template
Before : We checked ~1000 times => 100sec due to array_shift
After : ~1sec

I'm not sure bitwise ops really belong into a templateing language...

That's a general statement to make without knowing why it was implemented at all... no one is forced to use them, however when you do need them, them not being available makes you have relegate something that should be in the view in the particular case I needed them, to be done in a controller instead, which would be quite a bit nastier in my case.

@jturmel: I do not doubt that there are some cases where bitwise operations are useful. I can't think of one of the top of my head, though I imagine that it could be useful when using bitwise right management or something like that. What I was trying to say is, that I don't really believe that there are enough significant use cases for bitwise ops to justify adding them to the core (I know, "You Don't Have To Use It!", but it isn't good to clutter the core with features nearly no one uses). Maybe you could give an example of what you needed them for?

It would be one thing if I was implementing some operator that didn't normally exist in PHP itself, but it seems a bit odd to even say that it's cluttering it up, it's 3 lines of code that add 3 missing standard operators from PHP.
Simply put, I have an object that gets passed to the template that has many properties, these properties are bit values, I need to do checks on them to select/deselect various checkboxes in a grid... this is the cleanest way to do it without mudding up controller code with view logic.

Why not adding ``<<`` and ``>>`` then @jturmel?
I don't have a particular use case but I think that if Twig includes those 3 operators, it should also support these 2 to be "complete". What do you think?
---------------------------------------------------------------------------
by jturmel at 2011/08/03 06:07:46 -0700
Of course, if you guys think we need the shifting operators as well, we can... but modifying data in the view seems much less practical than the one's I added, although I did miss NOT.
---------------------------------------------------------------------------

I forgot about ``~`` but sure it should be included as well.
As for ``<<`` and ``>>``, they could also be used for verifying grant access for example in some implementations.
``{% if some_var << some_other_var & 1 %}``

f5b9df9 added `if` modifier support to for loop like {% for k in v if k is odd %}

[1.2] added `if` modifier support to for loop
Hi.
I'm one of Twig users who love it so much. :)
I've made a patch for adding `if` modifier support to `for` loop in Twig.
Example:
<pre>
{% for n in range(0, 5) if n is odd %}
{{ n }}
{% endfor %}
</pre>
Output:
<pre>
1
3
5
</pre>
This idea comes from Python's list comprehensions. (like `[n for n in range(0,6) if n % 2 == 1]`)
Here is another example.
Before:
<pre>
{% set no_items = true %}
{% for item in items %}
{% if item.available %}
{% set no_items = false %}
{{ item.name }}
{% endif %}
{% endfor %}
{% if no_items %}
No items available.
{% endif %}
</pre>
After:
<pre>
{% for item in items if item.available %}
{{ item.name }}
{% else %}
No items available.
{% endfor %}
</pre>
I hope you like it. But If not, just ignore this request. :)
Thanks.

I like it! I will schedule it for inclusion in Twig 1.2. Thanks.

I think the idea per se is interesting. But I just checked all Twig templates in my whole codebase and couldn't find any use for it. What was your practical use for this feature @kotas?
---------------------------------------------------------------------------
by kotas at 2011/06/27 01:52:48 -0700
@nikic My practical use is shown as the second example in the body of this pull request.
Sometimes you need to "filter" an array by seeing its element's property like "item.available" or by some condition like "item.price >= 500".
To do this, in the current version of Twig, you have to write "for" and "if" as nested scopes. And if you want to write {% else %} of the "for" loop, you have to make a temporary variable to see if all elements are skipped.
I think this feature is not essential, but makes templates clean.

The thing about `else` seems plausible. +1

Also +1. that makes some very clean template code.
