 |
|
Since HTML markup almost always requires both an opening and a closing tag, and such code is sometimes dependent upon a condition, it is too often that code duplication for the opening and closing tags occurs:
| Code: |
{if $someContition && $someObject == 37 && $addAsLink}
<a href="http://example_com/">
{/if}
some text
{if $someContition && $someObject == 37 && $addAsLink}
</a>
{/if}
|
And for cases when you have multiple cases for the surrounding code, or nested cases and conditions, the code becomes very ugly and hard to read. What I'm proposing is a tag that avoids such code duplication:
| Code: |
{try $someContition && $someObject == 37 && $addAsLink}
<a href="http://example_com/">
{finally}some text{/finally}
</a>
{/try}
|
The {try} block will print normally if the condition is true, but if false will only print any contained {finally} blocks. This emulates standard try/finally code behavior of languages, and should be familiar to most developers.
Nesting is possible:
| Code: |
{try $someContition && $someObject == 37 && $addAsLink}
<a href="http://example_com/">
{try $highlight}
<b>
{finally}some text{/finally}
</b>
{/try}
</a>
{/try}
|
Sometimes you need to alternate between different conditions, and even have a default value (if all else fails):
| Code: |
{try $someContition && $someObject == 37 && $addAsLink}
<a href="http://example_com/">
{catchtry $hard_highlight}
<b>
{catchtry $simple_highlight}
<i>
{catch}
<span class="simple">
{finally}some text{/finally}
</span>
{/catch}
</i>
{/catchtry}
</b>
{/catchtry}
</a>
{/try}
|
The three new tags {try}, {catchtry} and {catch} are the functional equivalent of {if}, {elseif} and {else}.
I think this would save a lot of code, and make markup cleaner and more functional.
As for implementation, it should not be too hard if done correctly. I could provide assistance if anyone is interested. |

| that would be confusing has hell to a typical html designer. you can implement the try stuff yourself if you really want it. everything here can be accomplished with if/else blocks, and maybe some help from includes or template inheritance. |
