# Setting up Etherpad (optional)
|
|
|
|
[Etherpad](https://etherpad.org) is an open source collaborative text editor that can be embedded in a Matrix chat room using the [Dimension integrations manager](https://dimension.t2bot.io) or used as standalone web app.
|
|
|
|
When enabled together with the Jitsi audio/video conferencing system (see [our docs on Jitsi](configuring-playbook-jitsi.md)), it will be made available as an option during the conferences.
|
|
|
|
## Adjusting the playbook configuration
|
|
|
|
To enable Etherpad, add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file:
|
|
|
|
```yaml
|
|
etherpad_enabled: true
|
|
|
|
# Uncomment and adjust this part if you'd like to enable the admin web UI
|
|
# etherpad_admin_username: YOUR_USERNAME_HERE
|
|
# etherpad_admin_password: YOUR_PASSWORD_HERE
|
|
```
|
|
|
|
### Adjusting the Etherpad URL
|
|
|
|
By default, this playbook installs Etherpad on the `etherpad.` subdomain (`etherpad.example.com`) and requires you to [adjust your DNS records](#adjusting-dns-records).
|
|
|
|
By tweaking the `etherpad_hostname` and `etherpad_path_prefix` variables, you can easily make the service available at a **different hostname and/or path** than the default one.
|
|
|
|
Example additional configuration for your `inventory/host_vars/matrix.example.com/vars.yml` file:
|
|
|
|
```yaml
|
|
# Switch to the domain used for Matrix services (`matrix.example.com`),
|
|
# so we won't need to add additional DNS records for Etherpad.
|
|
etherpad_hostname: "{{ matrix_server_fqn_matrix }}"
|
|
|
|
# Expose under the /etherpad subpath
|
|
etherpad_path_prefix: /etherpad
|
|
```
|
|
|
|
|
|
## Adjusting DNS records
|
|
|
|
Once you've decided on the domain and path, **you may need to adjust your DNS** records to point the Etherpad domain to the Matrix server.
|
|
|
|
By default, you will need to create a CNAME record for `etherpad`. See [Configuring DNS](configuring-dns.md) for details about DNS changes.
|
|
|
|
If you've decided to reuse the `matrix.` domain, you won't need to do any extra DNS configuration.
|
|
|
|
## Installing
|
|
|
|
After configuring the playbook and potentially [adjusting your DNS records](#adjusting-dns-records), run the [installation](installing.md) command: `just install-all` or `just setup-all`
|
|
|
|
## Usage
|
|
|
|
The Etherpad UI should be available at `https://etherpad.example.com`, while the admin UI (if enabled) should then be available at `https://etherpad.example.com/admin`.
|
|
|
|
If you've [decided on another hostname or path-prefix](#decide-on-a-domain-and-path) (e.g. `https://matrix.example.com/etherpad`), adjust these URLs accordingly before usage.
|
|
|
|
|
|
### Managing / Deleting old pads
|
|
|
|
If you want to manage and remove old unused pads from Etherpad, you will first need to able Admin access as described above.
|
|
|
|
Then from the plugin manager page (`https://etherpad.example.com/admin/plugins`, install the `adminpads2` plugin. Once installed, you should have a "Manage pads" section in the Admin web-UI.
|
|
|
|
|
|
### How to use Etherpad widgets without an Integration Manager (like Dimension)
|
|
|
|
This is how it works in Element, it might work quite similar with other clients:
|
|
|
|
To integrate a standalone Etherpad in a room, create your pad by visiting `https://etherpad.example.com`. When the pad opens, copy the URL and send a command like this to the room: `/addwidget URL`. You will then find your integrated Etherpad within the right sidebar in the `Widgets` section.
|
|
|
|
|
|
### Set Dimension default to the self-hosted Etherpad (optional)
|
|
|
|
If you decided to install [Dimension integration manager](configuring-playbook-dimension.md) alongside Etherpad, the Dimension administrator users can configure the default URL template.
|
|
|
|
The Dimension configuration menu can be accessed with the sprocket icon as you begin to add a widget to a room in Element. There you will find the Etherpad Widget Configuration action beneath the _Widgets_ tab.
|
|
|
|
|
|
#### Removing the integrated Etherpad chat
|
|
|
|
If you wish to disable the Etherpad chat button, you can do it by appending `?showChat=false` to the end of the pad URL, or the template.
|
|
|
|
Example: `https://etherpad.example.com/p/$roomId_$padName?showChat=false`
|
|
|
|
|
|
## Known issues
|
|
|
|
If your Etherpad widget fails to load, this might be due to Dimension generating a Pad name so long, the Etherpad app rejects it.
|
|
|
|
`$roomId_$padName` can end up being longer than 50 characters. You can avoid having this problem by altering the template so it only contains the three word random identifier `$padName`.
