Pico Excerpt

This is the repository of Pico's official PicoExcerpt plugin.

Pico is a stupidly simple, blazing fast, flat file CMS. See http://picocms.org/ for more info.

This plugin exists for historic reasons only and should not be used!

PicoExcerpt is a simple plugin that creates excperts of all your pages and makes them available using {{ page.excerpt }}. Installing this plugin is highly discouraged, because it depends on Pico's official PicoParsePagesContent plugin, that has a significant negative impact on your website's performance.

The main reason Pico started parsing the Markdown contents of all pages (see PicoParsePagesContent), was the desire for automatically generated page excerpts. We later realized that this is the wrong approach and started searching for alternatives - and we think we found a better solution. We recommend to part from the concept of automatically generated excerpts. Instead, you should use the Description meta header to write excerpts on your own. Starting with Pico 1.0 you can use %meta.*% placeholders in your Markdown files, so you don't have to repeat yourself - simply add %meta.description% to the page content and Pico will replace it with your excerpt.

By popular request we removed parsing the Markdown contents of all pages with Pico 1.0. This significantly improved Pico's performance. To preserve backwards compatibility (BC) we introduced the PicoParsePagesContent and PicoExcerpt plugins. Both plugins have been removed from Pico's default installation with Pico 2.0, but you can still install them manually.

Install

If you're using a composer-based installation of Pico (e.g. picocms/pico-composer), simply open a shell on your server, navigate to Pico's install directory (e.g. /var/www/html) and run composer require phrozenbyte/pico-excerpt (via Packagist.org). That's it!

If you're rather using one of Pico's pre-built release packages, you must install the PicoParsePagesContent plugin first. After you've installed PicoParsePagesContent, create a empty plugins/PicoExcerpt directory in Pico's install directory (e.g. /var/www/html) on your server. Then download PicoExcerpt's latest source package and upload all containing files (esp. PicoExcerpt.php) into said plugins/PicoExcerpt directory (resulting in plugins/PicoExcerpt/PicoExcerpt.php).

PicoExcerpt requires Pico 1.0+

Config

PicoExcerpt is disabled by default due to the significant negative performance impact of the required PicoParsePagesContent plugin. You can enable the plugin by adding the following to your config/config.yml:

PicoExcerpt.enabled: true

PicoExcerpt itself has no config options.
