# Configuration
This file describe the configuration, it is recommended to edit the relevant *.secret.exs file instead of the others founds in the ``config`` directory.
If you run Pleroma with ``MIX_ENV=prod`` the file is ``prod.secret.exs``, otherwise it is ``dev.secret.exs``.
## Pleroma.Upload
* `uploader`: Select which `Pleroma.Uploaders` to use
* `filters`: List of `Pleroma.Upload.Filter` to use.
* `base_url`: The base URL to access a user-uploaded file. Useful when you want to proxy the media files via another host.
* `proxy_remote`: If you\'re using a remote uploader, Pleroma will proxy media requests instead of redirecting to it.
* `proxy_opts`: Proxy options, see `Pleroma.ReverseProxy` documentation.
Note: `strip_exif` has been replaced by `Pleroma.Upload.Filter.Mogrify`.
## Pleroma.Uploaders.Local
* `uploads`: Which directory to store the user-uploads in, relative to pleroma’s working directory
## Pleroma.Upload.Filter.Mogrify
* `args`: List of actions for the `mogrify` command like `"strip"` or `["strip", "auto-orient", {"impode", "1"}]`.
## Pleroma.Upload.Filter.Dedupe
No specific configuration.
## Pleroma.Upload.Filter.AnonymizeFilename
This filter replaces the filename (not the path) of an upload. For complete obfuscation, add
`Pleroma.Upload.Filter.Dedupe` before AnonymizeFilename.
* `text`: Text to replace filenames in links. If empty, `{random}.extension` will be used.
## Pleroma.Mailer
* `adapter`: one of the mail adapters listed in [Swoosh readme](https://github.com/swoosh/swoosh#adapters), or `Swoosh.Adapters.Local` for in-memory mailbox.
* `api_key` / `password` and / or other adapter-specific settings, per the above documentation.
An example for Sendgrid adapter:
```exs
config :pleroma, Pleroma.Mailer,
adapter: Swoosh.Adapters.Sendgrid,
api_key: "YOUR_API_KEY"
```
An example for SMTP adapter:
```exs
config :pleroma, Pleroma.Mailer,
adapter: Swoosh.Adapters.SMTP,
relay: "smtp.gmail.com",
username: "YOUR_USERNAME@gmail.com",
password: "YOUR_SMTP_PASSWORD",
port: 465,
ssl: true,
tls: :always,
auth: :always
```

* `background_upload_limit`: File size limit of user’s profile backgrounds
* `banner_upload_limit`: File size limit of user’s profile banners
* `registrations_open`: Enable registrations for anyone, invitations can be enabled when false.
* `invites_enabled`: Enable user invitations for admins (depends on `registrations_open: false`).
* `account_activation_required`: Require users to confirm their emails before signing in.
* `federating`: Enable federation with other instances
* `federation_reachability_timeout_days`: Timeout (in days) of each external federation target being unreachable prior to pausing federating to it.
* `allow_relay`: Enable Pleroma’s Relay, which makes it possible to follow a whole instance
* `rewrite_policy`: Message Rewrite Policy, either one or a list. Here are the ones available by default:
* `Pleroma.Web.ActivityPub.MRF.NoOpPolicy`: Doesn’t modify activities (default)
* `Pleroma.Web.ActivityPub.MRF.DropPolicy`: Drops all activities. It generally doesn’t makes sense to use in production
* `Pleroma.Web.ActivityPub.MRF.SimplePolicy`: Restrict the visibility of activities from certains instances (See ``:mrf_simple`` section)
* `Pleroma.Web.ActivityPub.MRF.RejectNonPublic`: Drops posts with non-public visibility settings (See ``:mrf_rejectnonpublic`` section)

* `always_show_subject_input`: When set to false, auto-hide the subject field when it's empty.
* `extended_nickname_format`: Set to `true` to use extended local nicknames format (allows underscores/dashes). This will break federation with
older software for theses nicknames.

An example to enable ONLY ExSyslogger (f/ex in ``prod.secret.exs``) with info and debug suppressed:
```
config :logger,
backends: [{ExSyslogger, :ex_syslogger}]
config :logger, :ex_syslogger,
level: :warn
```
Another example, keeping console output and adding the pid to syslog output:
```
config :logger,
backends: [:console, {ExSyslogger, :ex_syslogger}]
config :logger, :ex_syslogger,
level: :warn,

Frontends can access these settings at `/api/pleroma/frontend_configurations`
To add your own configuration for PleromaFE, use it like this:
`config :pleroma, :frontend_configurations, pleroma_fe: %{redirectRootNoLogin: "/main/all", ...}`
These settings need to be complete, they will override the defaults. See `priv/static/static/config.json` for the available keys.

```
This config contains two queues: `federator_incoming` and `federator_outgoing`. Both have the `max_jobs` set to `50`.
## Pleroma.Web.Federator.RetryQueue
* `enabled`: If set to `true`, failed federation jobs will be retried
* `max_jobs`: The maximum amount of parallel federation jobs running at the same time.

## :hackney_pools

There's three pools used:
* `:federation` for the federation jobs.
You may want this pool max_connections to be at least equal to the number of federator jobs + retry queue jobs.
* `:media` for rich media, media proxy
* `:upload` for uploaded media (if using a remote uploader and `proxy_remote: true`)
For each pool, the options are:
* `max_connections` - how much connections a pool can hold
* `timeout` - retention duration for connections
## :auto_linker
Configuration for the `auto_linker` library:
* `class: "auto-linker"` - specify the class to be added to the generated link. false to clear
* `rel: "noopener noreferrer"` - override the rel attribute. false to clear
* `new_window: true` - set to false to remove `target='_blank'` attribute
* `scheme: false` - Set to true to link urls with schema `http://google.com`
