# Grav Breadcrumbs Plugin
|
|
|
|
|
|
|
|
`Breadcrumbs` is a [Grav](http://github.com/getgrav/grav) plugin that adds links to the previous pages (following the hierarchical structure).
|
|
It is particularly useful if you are using Grav to run a blog.
|
|
|
|
# Installation
|
|
|
|
Installing the Breadcrumbs plugin can be done in one of two ways. Our 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.
|
|
|
|
## GPM Installation (Preferred)
|
|
|
|
The simplest way to install this plugin is via the [Grav Package Manager (GPM)](http://learn.getgrav.org/advanced/grav-gpm) through your system's Terminal (also called the command line). From the root of your Grav install type:
|
|
|
|
bin/gpm install breadcrumbs
|
|
|
|
This will install the Breadcrumbs plugin into your `/user/plugins` directory within Grav. Its files can be found under `/your/site/grav/user/plugins/breadcrumbs`.
|
|
|
|
## 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 `breadcrumbs`. You can find these files either on [GitHub](https://github.com/getgrav/grav-plugin-breadcrumbs) or via [GetGrav.org](http://getgrav.org/downloads/plugins#extras).
|
|
|
|
You should now have all the plugin files under
|
|
|
|
/your/site/grav/user/plugins/breadcrumbs
|
|
|
|
>> NOTE: This plugin is a modular component for Grav which requires [Grav](http://github.com/getgrav/grav), the [Error](https://github.com/getgrav/grav-plugin-error) and [Problems](https://github.com/getgrav/grav-plugin-problems) plugins, and a theme to be installed in order to operate.
|
|
|
|
# Usage
|
|
|
|
The `breadcrumbs` plugin doesn't require any configuration. The moment you install it, it is ready to use.
|
|
|
|
Something you might want to do is to override the look and feel of the breadcrumbs, and with Grav it is super easy.
|
|
|
|
Copy the template file [breadcrumbs.html.twig](templates/partials/breadcrumbs.html.twig) into the `templates` folder of your custom theme, and that is it.
|
|
|
|
```
|
|
/your/site/grav/user/themes/custom-theme/templates/partials/breadcrumbs.html.twig
|
|
```
|
|
|
|
You can now edit the override and tweak it however you prefer.
|
|
|
|
## Per-page Settings
|
|
|
|
The following options are available for use in a page's YAML frontmatter, placed within the `breadcrumbs` mapping:
|
|
|
|
| Option | Default | Values | Description |
|
|
|-------------|---------|-------------------|--------------------------------------------------------------------------------------|
|
|
| `max_depth` | `true` | `true` or `false` | Determines whether breadcrumbs for pages beneath the current page will be generated. |
|
|
|
|
### Example Per-page Settings
|
|
|
|
```yaml
|
|
---
|
|
title: Some page you wrote
|
|
breadcrumbs:
|
|
may_descend: false # Breadcrumbs will not be generated for pages underneath this one.
|
|
---
|
|
```
|
|
|
|
# Updating
|
|
|
|
As development for the Breadcrumbs plugin continues, new versions may become available that add additional features and functionality, improve compatibility with newer Grav releases, and generally provide a better user experience. Updating Breadcrumbs is easy, and can be done through Grav's GPM system, as well as manually.
|
|
|
|
## GPM Update (Preferred)
|
|
|
|
The simplest way to update this plugin is via the [Grav Package Manager (GPM)](http://learn.getgrav.org/advanced/grav-gpm). You can do this with this by navigating to the root directory of your Grav install using your system's Terminal (also called command line) and typing the following:
|
|
|
|
bin/gpm update breadcrumbs
|
|
|
|
This command will check your Grav install to see if your Breadcrumbs plugin is due for an update. If a newer release is found, you will be asked whether or not you wish to update. To continue, type `y` and hit enter. The plugin will automatically update and clear Grav's cache.
|
|
|
|
## Manual Update
|
|
|
|
Manually updating Breadcrumbs is pretty simple. Here is what you will need to do to get this done:
|
|
|
|
* Delete the `your/site/user/plugins/breadcrumbs` directory.
|
|
* Download the new version of the Breadcrumbs plugin from either [GitHub](https://github.com/getgrav/grav-plugin-breadcrumbs) or [GetGrav.org](http://getgrav.org/downloads/plugins#extras).
|
|
* Unzip the zip file in `your/site/user/plugins` and rename the resulting folder to `breadcrumbs`.
|
|
* Clear the Grav cache. The simplest way to do this is by going to the root Grav directory in terminal and typing `bin/grav clear-cache`.
|
|
|
|
> Note: Any changes you have made to any of the files listed under this directory will also be removed and replaced by the new set. Any files located elsewhere (for example a YAML settings file placed in `user/config/plugins`) will remain intact.
|
|
|
|
## Configuration
|
|
|
|
Simply copy the `user/plugins/breadcrumbs/breadcrumbs.yaml` into `user/config/plugins/breadcrumbs.yaml` and make your modifications.
|
|
|
|
```
|
|
enabled: true
|
|
show_all: true
|
|
built_in_css: true
|
|
include_home: true
|
|
include_current: true
|
|
icon_home: ''
|
|
icon_divider_classes: 'fa fa-angle-right'
|
|
link_trailing: false
|
|
```
|
|
|
|
Options are pretty self explanatory.
