# Reference

Egenverk Docs Viewer · v2.10.0 · WordPress 5.0+, PHP 7.4+ · Updated 2026-10-14

## Filter: egenverk_dv_capability

Sets the capability needed to open **Tools → Docs Viewer**, read and search. The default is `manage_options`. If the filter returns anything other than a string, or an empty string, `manage_options` is used.

Put the filter in a small must-use plugin, for example `wp-content/mu-plugins/docs-viewer-access.php`:

```php
<?php
add_filter( 'egenverk_dv_capability', function () {
	return 'edit_posts';
} );
```

Users with that capability see **Tools → Docs Viewer**, can read every scanned document, and get the links on the Plugins screen. They cannot scan or change the link setting; scanning, the multisite rescan and the link setting always require `manage_options`. If nothing has been scanned yet, the viewer asks them to have an administrator run a scan.

## Viewer addresses

The viewer is at `wp-admin/tools.php?page=egenverk-docs-viewer`. You can use the parameters below in bookmarks and links:

| Parameter | What it does |
|-----------|--------------|
| `dv_plugin` | Which plugin or theme is shown: the plugin's folder name, `theme:` followed by the theme's folder name, or `mu:` followed by the must-use plugin's folder name |
| `dv_file` | The file's path inside the folder, for example `docs/guide.md` |
| `dv_mode` | `preview` (default) or `raw` |
| `dv_search` | A search query |
| `dv_version` | Opens a changelog at the section for that version |

A `#heading` at the end of the address opens the document at that heading. The older address `wp-admin/admin.php?page=egenverk-docs-viewer` redirects here and keeps the parameters.

## Events that rebuild the index

The index is rebuilt once, at the end of the request, when:

- a plugin or theme is installed or updated
- a plugin is activated, deactivated or deleted
- a theme is deleted
- Docs Viewer is activated

This also covers updates run from WP-Cron or WP-CLI. On multisite, where plugins are shared but each site has its own index, the other sites rebuild their index on their next admin visit by an administrator.

## Stored options
