I have a question too but first here's what I have done.
I did a plugin named partial that is basically include plugin.
If the template is multiline you can assign indent parameter like this:
{partial tpl="nav" indent=" "}
It is the same amount of white space that is in front of the partial syntax.
So now the output is indending the right way. I need this because I'm writing open source software for making static HTML sites (prototyping purposes). Output goes to programmer so it has to look the same way I write it.
| Code: |
$a_output = explode("\n", $output);
$first_line = true;
foreach ($a_output as $key => $var) {
if (!$first_line || $params["fullindent"]) {
$a_output[$key] = $params["indent"] . $var;
} else {
$first_line = false;
$a_output[$key] = $var;
}
}
// fix: remove lines with only spaces
$a_outputFinal = array();
foreach ($a_output as $key => $var) {
if (trim($var) != "") {
$a_outputFinal[$key] = $var;
}
}
return implode("\n", $a_outputFinal);
}
?>

fullindent parameter is if I want to for some reason indent the first line too.
There was some kind of bug with whitespaces so I did the // fix part. It was so long ago that I don't evene remember what it was 
Anyways, now everything is good!
But is there somehow possible to find automatically how many spaces I need to indent? |

The Browser does not need indentation at all. In fact, if you remove all the whitespace between tags you not only reduce the size to transfer, but also reduce the overhead of the browser's html parser. That is, it does not need to hold whitespace nodes in memory. In production environments you should remove this unnecessary data.
That being said, for development a proper indentation may help. Maybe http://de.php.net/tidy can help you. Otherwise I don't see a way around writing an output-filter that implements some sort of simple parser to build a dom and serializing it with injecting indentation. If you don't want to write your own parser, you could try DOMDocument::loadHTML.
keep in mind that this should only be done for development environments. You not only produce more data to transfer, but also waste time producing it. |

Thanx for input, globe!
I do HTML prototypes that go on to developers. Maby you heard of StaticMatic? My software is much like that but it uses Smarty and php. You write some templates and build static html from it (while looking at localhost/text.html, it always shows the Smarty generated page and writes text.html to disk).
Nice indenting is for developers who need to cut it in half again and make it dynamic.
I totally agree that extra white-space is bad in web.
So for now my plugin that gets the indent level it needs as parameter is the way to go...
Tidy has it's own indenting logic and changes stuff the way I don't want. But I guess having the possibility of using Tidy would come in handy.
