Parse the file meta using the Symfony2 YAML Component.

[msosvi]

Allow YAML format in meta info and now custom meta plugin isn't needed.

I'm not familiar with YAML, so pardon the likely ignorance of this question, but: how does this enhance Pico? Can you give an example in the default template?

[msosvi]

By using YAML, Pico doesn't need a custom meta plugin. Also with YAML format you can describe a collection that is converted to a PHP array (tags collection, for example).

YAML is used in Jekyll, the static site generator behind Github Pages, for page meta info.

This would be awesome. It would make it much easier to migrate from Jekyll to Pico. I got interested in Pico because it is basically like Jekyll but without a build step. Different header format was a bit disappointment because I could not just drop in my Jekyll markdown files.

Also Github supports YAML headers in markdown:

Actually the metadata syntax is now already a subset of YAML. The comment syntax is just incompatible with the de facto style used in Jekyll, Github, Assemble.io, Wintersmith.io and many others. They use three dashes (---) at the start and at the end of the metadata section instead of C style comments. I'd love to see Pico supporting dashes in addition to the current one.

Example:

---
Title: Foo  Bar
---

# Header 1

This is a great feature! I'm not a developer and I have been hours trying to add custom meta to pages. Right nowwe have to use a hook to add custom meta to pages but with this everything inside /**/ of each page will be cosidered as a meta field. Is that right?

I'm looking forward to build a lot of websites using Pilot. But custom meta is holding me. I do prefer this way.

[msosvi]

You are right, with this change Pico doesn't need a custom meta plugin.

Did this feature get shelved? I'd like to give my vote for integrating it +1

There is no need to add the YAML Symphony component, just changing the regular expression to this :

/**
     * Parses the file meta from the txt file header
     *
     * @param string $content the raw txt content
     * @return array $headers an array of meta values
     */
    protected function read_file_meta($content){
        global $config;

        $headers = array();

        // Add support for custom headers by hooking into the headers array
        // Is no longer needed but kept for compatibility reasons.
        $this->run_hooks('before_read_file_meta', array(&$headers));

        // Add any meta-headers from your *.md-files.
        if (preg_match_all('/^[-]{3}.(.*?)[-]{3}/ims', $content, $match) && isset($match[1]) && isset($match[1][0])) {
                    $lines = array_filter(explode("\n", $match[1][0]));
                    foreach ($lines as $line) {
                            if (strpos($line, ':') == true) {
                                    list($key, $val) = explode(':', $line);
                                    $headers[trim(strtolower($key))] = trim($val);
                            }
                    }

                    if (isset($headers['date'])) $headers['date_formatted'] = date($config['date_format'], strtotime($headers['date']));

                return $headers;
        }
    }

except if you plan tu use multi-dimentional arrays in meta in the future ... but actualy it's not implemented in Pico.

i already use this and it works ...
