Archive and tags pages not working as designed when using the Thymeleaf sample project

[vindevoy]

Hi,

I have started to develop my blog with JBake + Thymeleaf. When adding features, I discovered that you cannot update the value of a variable in thymeleaf. But, that is used in the templates/archive.thyme and templates/tags.thyme.

<div th:each="post : ${posts}" th:with='last_month=null' th:remove='tag'>
  <h3 th:if='${last_month!=#dates.format(post.date,"MMMM yyyy")}' th:text='${#dates.format(post.date,"MMMM yyyy")}'>June 2014</h3>
		
  <h4><span th:text='${#dates.format(post.date,"dd")}' th:remove='tag'/> - <a th:href="${content.rootpath+post.uri}" th:text='${post.title}' href="foo.html">Post title</a></h4> 
 <span th:remove='all' th:with='last_month = ${#dates.format(post.date,"MMMM yyyy")}'/>
</div>

You set the variable and then update it, but that does not work. As soon as you leave scope, your variable is reset. So, after the span (so basically immediately) your last_month is null again. When you run the site, you will see that there is no grouping as with other techniques.

I really wanted grouping, so I updated the code to have this working. I hereby post my solution. The solution is similar for both pages, just updated published_posts with tag_posts, below is the code for archive.

<th:block th:with="total_posts = *{#lists.size(published_posts)}">
  <th:block th:if="*{total_posts != 0}" th:with="first_post = *{posts[0]}">
    <h4 th:text="*{#dates.format(first_post.date,'MMMM yyyy')}"></h4>
    <span class="font-weight-bold" th:text="*{#dates.format(first_post.date,'dd')}"/> -
    <a th:href="*{content.rootpath + first_post.uri}" th:text="*{first_post.title}" href=""></a>
    <br/>

    <th:block th:if="*{total_posts &gt; 1}" th:each="i : *{#numbers.sequence( 1, total_posts - 1)}"> 
      <th:block th:with="previous_post = *{posts[i - 1]}, current_post = *{posts[i]}">
        <th:block th:if="*{#dates.format(previous_post.date,'MMMM yyyy')} != *{#dates.format(current_post.date,'MMMM yyyy')}">
          <p></p>
	  <h4 th:text="*{#dates.format(current_post.date,'MMMM yyyy')}"></h4>
        </th:block>

        <span class="font-weight-bold" th:text="*{#dates.format(current_post.date,'dd')}"/> -
        <a th:href="*{content.rootpath + current_post.uri}" th:text="*{current_post.title}" href=""></a> 
        <br/>
      </th:block>
    </th:block>
  </th:block>
</th:block>

My blog is still in development phase, but you can see the first results in http://dv.blog.yves.vindevogel.net. The final URL will be without the dv.

I have my own GitLab running, but I am pushing the changes on protected branches (develop and master) also to GitHub: https://github.com/vindevoy/blog-yves-vindevogel-net.git

Hi Yves,

Yeah this was raised on the Thymeleaf example project repo: jbake-org/jbake-example-project-thymeleaf#5

If you have time would you mind raising a PR on the Thymeleaf example project repo with your fix applied to archive and tags?

Thanks

[vindevoy]

Yes sure.  I will clone and modify. I have also launched another project on GitHub to get the startBootstrap templates in JBake https://github.com/vindevoy/startbootstrap-jbake-thymeleaf Currently, develop is still empty.  I have not yet finished the first code block.  Develop for me must be kept clean. Branch is vindevoy-all-split Jonathan Bullock wrote on 27/10/2018 10:53:

Thanks @vindevoy have a look at #370 for the long term goal for 3rd party templates.
