Timeline Plugin
The Timeline-plugin is for Grav CMS, and lets you create and manage timelines in an ordered, hierarchical manner. Timelines can be nested within each other, minutely customized on a page-level, and further customized with your own templates and styles. A demo is available, and demo content can be found in /pages.
Installation
Installing the Timeline-plugin can be done in one of two ways. The GPM (Grav Package Manager) installation method enables you to quickly and easily install the plugin with a simple terminal command, while the manual method enables you to do so via a zip file.
Requirements
This plugin will only work with Grav v1.6 or higher, as it requires PHP v7.1 or higher. Dropping this requirement would mean devolving features, which the author is not inclined to do.
The intl-extension for PHP must be installed and enabled to use this plugin.
GPM Installation (Preferred)
The simplest way to install this plugin is via the Grav Package Manager (GPM) through your system's terminal (also called the command line). From the root of your Grav install type:
bin/gpm install timeline
This will install the Timeline-plugin into your /user/plugins
directory within Grav. Its files can be found under /your/site/grav/user/plugins/timeline
.
Manual Installation
To install this plugin, just download the zip version of this repository and unzip it under /your/site/grav/user/plugins
. Then, rename the folder to timeline
. You can find these files on GitHub or via GetGrav.org.
You should now have all the plugin files under
/your/site/grav/user/plugins/timeline
NOTE: This plugin is a modular component for Grav which requires Grav and the Error and Problems to operate.
Configuration
Before configuring this plugin, you should copy the user/plugins/timeline/timeline.yaml
to user/config/plugins/timeline.yaml
and only edit that copy.
Here is the default configuration and an explanation of available options:
enabled: true
language: en
order:
by: date
dir: asc
cache: native
truncate: 100
Settings and Usage
Variable | Default | Options | Note |
---|---|---|---|
enabled | true | true or false |
Enables or disables the plugin. |
language | en | string (2) | Any two-letter (ISO-639-1) language code. |
order: | |||
by | date | date , title , or folder |
Orders pages according to date, title, or folder-name. |
dir | asc | asc or desc |
Order pages ascending or descending. |
cache | native | native , persist , transient , or disabled |
Where to store plugin's internal data. |
truncate | 100 | int or boolean | Limits the amount of words in each note, to an integer or boolean state for default (100). |
Each timeline is structured with a Header (timeline.md
, Timeline-template) and Events (timeline_event.md
, Timeline Event-template). Headers are used as separators and can order their descendant Events, as well as contain normal fields such as title
, subtitle
, and content
. Events also render a formatted, localized date
(using date_format
and locale
), as well as an image
. In addition, Events are cast as Linked Data with JSON-LD, wherein type
, place
, locality
, and region
are used.
Printing
Two modes of printing are support: Pure text or with graphics. By default, graphics are included and the layout will typically emulate mobile-view - events will not alternate between odd and even. To print pure text, remove the print
-class from <div class="print timeline-wrapper col-12 col-sm-10 col-sm-offset-1 col-md-8 offset-md-2">
in timeline.html.twig.
Development
Use a SCSS-compiler, like LibSass, eg. node-sass and compile assets/timeline.scss
to assets/timeline.css
in the plugin-folder. For example: node-sass --watch --source-map true assets/timeline.scss assets/timeline.css
.
