lektor-read-full-post

Allows blog listing posts to be shortened with a link to the full post.

Install

lektor plugins add lektor-read-full-post

How to Use

Add the split-text to a blog post. It must be at the start of a line and be the only text on the line.
Only text above that line appears on the blog listing page.
All text appears on the post's dedicated page.

On the blog listing page, the post will end with the link-text, to the full post.

These options can be customized per post body type.

Config

Create configs/read-full-post.ini

This is a full example config

always-display = false
markdown-link-text = <br><br>[Read Full Post]({URL_PATH})
markdown-split-text = [//]: # (PLUGIN-READ-FULL-POST)
html-link-text = <br><br><a href="{URL_PATH}">Read Full Post</a>
html-split-text = <!-- PLUGIN-READ-FULL-POST -->

split-text : The text to split the blog post on.
link-text : The code to link to the full post.
always-display : If True, always display the link-text. If False, only display if blog post contains the split-text
{URL_PATH}: Will be replaced with the absolute URL to the full post.

Notice how the configs exist for html and markdown.
If the post body type is markdown, the markdown option is chosen. Same applies for html.
This is detected automatically so if you have another type eg rst you can add it.

Modify Templates

blog.html

This is a full sample of a blog.html template
This new line is required {% set child = plugin_read_full_post(child) %}
This processes the blog post.
It must come before render_blog_post.

{% extends "layout.html" %}
{% from "macros/blog.html" import render_blog_post %}
{% from "macros/pagination.html" import render_pagination %}
{% block title %}{{ this.title }}{% endblock %}
{% block body %}
  {% for child in this.pagination.items %}
    {% set child = plugin_read_full_post(child) %}
    {{ render_blog_post(child, from_index=true) }}
  {% endfor %}

  {{ render_pagination(this.pagination) }}
{% endblock %}

macros/blog.html

Below are two blocks of template code.
The first block is the required changes.
The second block is a full sample of macros/blog.html for reference.

  {% if from_index %}
      {{ post.body_short }}
  {% else %}
      {{ post.body }}
  {% endif %}

{% macro render_blog_post(post, from_index=false) %}
  <div class="blog-post">
  {% if from_index %}
    <h2><a href="{{ post|url }}">{{ post.title }}</a></h2>
  {% else %}
    <h2>{{ post.title }}</h2>
  {% endif %}
  <p class="meta">
    written by
    {% if post.twitter_handle %}
      <a href="https://twitter.com/{{ post.twitter_handle
        }}">{{ post.author or post.twitter_handle }}</a>
    {% else %}
      {{ post.author }}
    {% endif %}
    on {{ post.pub_date }}
  </p>
  {% if from_index %}
      {{ post.body_short }}
  {% else %}
      {{ post.body }}
  {% endif %}
  </div>
{% endmacro %}

How it works

The post.body is deepcopy to post.body_short.
The blog text is split() on the split text.
Index 0 of the split() is used on the blog listing page.
The original post.body becomes the join split. Therefore the split-text no longer exists.
