PhamlP renders PHP as comments, code isn't executed
So:
I quite like using Haml in ruby projects, and was testing it out in PHP. I've been trying PhamlP because it looks like it's not dead, whereas phpHaml and pHaml haven't been updated in nearly 4 years.
Now, the problem I have is the php code that PhamlP is parsing is showing up as comments in HTML instead of executing. Here's the test file, index.php:
include_once('haml/HamlParser.php');
$haml = new HamlParser(array('ugly'=>'false'));
$page = $haml->parse('test.haml');
echo $page;
Here's the test.haml file:
!!!
- $foo = 'bar'
%h1 Foo this
.test= $foo
and here's the output I get in the browser when I view source:
<?php
require_once '/Users/Andrew/Sites/eighty-b/_app/haml/HamlHelpers.php';
?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<?php $foo = 'bar'; ?><h1>Foo this</h1><div class="bar">This better fooacross multiple lines butstill in the bar div!</div><div class="test"><?php echo $foo; ?></div>
So, for instance, the line - $foo = 'bar' isn't being executed, it's somehow passing through to the browser as a comment.
How the heck do yo开发者_开发技巧u fix that?
Don't know it, but the obvious workaround would be to replace the echo $page with:
eval("?".">".$page); // oh nooooes, eval is evil!!!!!
I'd assume ->parse does just a conversion, and the output is supposed to be stored in a new .php output/template/cache file usually.
The point of it isn't so much to be evaluated - as it's to prepare PHP code, templates and minimize php/html markup, while keeping things as D.R.Y. as possible (that's my take anyways).
I find it easiest to simply have PHamlP render the page to PHP file, and then include the file. This example assumes you have a directory 'cache' that is chmoded to 755:
include_once('haml/HamlParser.php');
$haml = new HamlParser(array('ugly'=>'false'));
$page = $haml->parse('test.haml', 'cache');
require_once 'cache/test.php';
This way all the PHP code executes and you page displays correctly. The test.php file will be generated every time the page is loaded though, so you will want to remove the code to parse the Haml file in a production environment.
Long and barely related answer, but this is what I do. This was inspired by devers answer above
I use the guard ruby gem, and phamlp to automatically convert my .haml files into .php files
My guard file
require 'guard/plugin'
module ::Guard
class Phamlp < ::Guard::Plugin
def run_all
end
def run_on_changes(paths)
paths.each do |path|
puts path
puts File.dirname path
system "php hamlconverter.php #{path} #{File.dirname path}"
end
end
end
end
guard :phamlp do
watch(/^.+(\.haml)$/)
end
and haml converter.php
<?php require_once 'phamlp/haml/HamlParser.php';
$haml = new HamlParser(array('style'=>'nested', 'ugly'=>'compressed', 'debug'=>true));
$haml->parse($argv[1], $argv[2]); ?>
If u now run guard it will track your .haml files and if they change, it will convert them to .php files
