Pico CMS version 2: brackets in meta title

[bricebou]

Hi,

Working on the upgrade to Pico CMS v. 2, I've just met an issue that took me some time to understand.

I have two articles with a meta title beginning with a word between brackets:

Title: [Avancé] GCweb : Modier l'intitulé des champs

and these articles didn't show inside my category page, neither in the tag page.

Removing the brackets, they appear. I've tried to escape them (\[Avancé\]), to replace them with the hex code ([ and ]) but nothing. I've tried to disable the Parsedown Extra parser but without effect. It worked with my actual production Pico (but I think it's a 0.9 version).

Any idea ?

Thanks !

I don't really see a reason why matching the category by title is necessary, it's a rather error-prone approach (as you're experiencing right now). How about adding Category: my_category_1 to your root/supcategory/category/index.md (see https://github.com/picocms/Pico/issues/438#issue-335085179) and using the same Category meta header in your category page (root/supcategory/category/page.md) to match the page? You just have to replace the cate variable (meta.title right now) by meta["Category"].

That's not the issue...

The twig code with what you mentionned commented:

<h1>{{ meta.title }}</h1>
{# {% set cate = meta.title|trim %} #}
<ul class="wlist vtl categ">
    {% for page in pages %}
        {# {% if page.meta["Category"]|trim is sameas(cate) and page.meta["template"]|trim != 'category' %} #}
            <li>
                <a href="{{ page.url }}">
                    <time class="vtl_date meta" datetime="{{ page.date }}" ><span>{{ page.date|date("d/m/Y", "Europe/Paris")}}</span></time>
                    <div class="vtl_point"><i class="fa"></i></div>
                    <div class="vtl_label">
                        {{ page.title }}
                    </div>
                </a>
            </li>
        {# {% endif %} #}
    {% endfor %}
</ul>

And the HTML output for two articles which title starts with [Avancé]:

<li>
    <a href="http://dev.localhost/tutos/LaTeX">
        <time class="vtl_date meta" datetime="" ><span>26/06/2018</span></time>
        <div class="vtl_point"><i class="fa"></i></div>
        <div class="vtl_label">
            LaTeX
        </div>
    </a>
</li>
<li>
    <a href="http://dev.localhost/tutos/GCweb/GCweb_nom_champs">
        <time class="vtl_date meta" datetime="" ><span>26/06/2018</span></time>
        <div class="vtl_point"><i class="fa"></i></div>
        <div class="vtl_label">

        </div>
    </a>
</li>
<li>
    <a href="http://dev.localhost/tutos/GCweb/GCweb_champs_perso">
        <time class="vtl_date meta" datetime="" ><span>26/06/2018</span></time>
        <div class="vtl_point"><i class="fa"></i></div>
        <div class="vtl_label">

        </div>
    </a>
</li>
<li>
    <a href="http://dev.localhost/tutos/GCweb">
        <time class="vtl_date meta" datetime="" ><span>26/06/2018</span></time>
        <div class="vtl_point"><i class="fa"></i></div>
        <div class="vtl_label">
            GCweb
        </div>
    </a>
</li>

As you can see, the vtl_label div appears empty for two entries. Here are the meta headers of these two files:

I've tried to switch to the default theme and to access the page where I have a meta title with brackets.

Title: [Avancé] GCweb : Modier l'intitulé des champs

And here is the PHP error I get:

[Wed Jun 27 22:15:57.843942 2018] [php7:error] [pid 21610] [client ::1:40088] PHP Fatal error:  Uncaught Symfony\\Component\\Yaml\\Exception\\ParseException: Unexpected characters near " GCweb : Modier l'intitul\xc3\xa9 des champs" at line 7 (near "Title: [Avanc\xc3\xa9] GCweb : Modier l'intitul\xc3\xa9 des champs"). in /home/bbrice/webdev/www-dev/vendor/symfony/yaml/Inline.php:76\nStack trace:\n#0 /home/bbrice/webdev/www-dev/vendor/symfony/yaml/Parser.php(536): Symfony\\Component\\Yaml\\Inline::parse('[Avanc\\xC3\\xA9] GCweb...', false, false, false, Array)\n#1 /home/bbrice/webdev/www-dev/vendor/symfony/yaml/Parser.php(258): Symfony\\Component\\Yaml\\Parser->parseValue('[Avanc\\xC3\\xA9] GCweb...', false, false, false, 'mapping')\n#2 /home/bbrice/webdev/www-dev/vendor/symfony/yaml/Parser.php(78): Symfony\\Component\\Yaml\\Parser->doParse('Title: [Avanc\\xC3\\xA9...', false, false, false)\n#3 /home/bbrice/webdev/www-dev/vendor/picocms/pico/lib/Pico.php(1335): Symfony\\Component\\Yaml\\Parser->parse('Title: [Avanc\\xC3\\xA9...')\n#4 /home/bbrice/webdev/www-dev/vendor/picocms/pico/lib/Pico.php(442): Pico->parseFileMeta('/*\\nTitle: [Avan...', Array)\n#5  in /home/bbrice/webdev/www-dev/vendor/symfony/yaml/Inline.php on line 76

I've tried without any success with double quotes, single quotes...

Title: "[Avancé] GCweb : Ajout de champs personnalisés"

Works fine for me with double quotes:

Hum... inexplicable, but today, after booting my computer, it works just with double quotes...

Sorry for the noise...
