The plugin **history** is used to check when someone has been seen for the last time on a channel. For that purpose,
irccd needs to be on that channel forever if possible.

## Installation

The plugin **history** is distributed with irccd. To enable it add the following to your `plugins` section:

````ini
[plugins]
history = ""
````

## Usage

The plugin **history** only reacts to the special command. It understands `seen` and `said` sub commands.

  - The sub command `seen` tells you when the user has been seen for the last time.
  - The sub command `said` tells you what the user has said for the last time.

Example:

````nohighlight
markand: !history seen jean
irccd: markand, the last time I've seen jean was on 18/01/1989 at 20:55
markand: !history said jean
irccd: markand, the last thing that jean said was: hello world
````

## Configuration

The following options are available under the `[plugin.history]` section:

  - **file**: (string) path to the JSON file for saving information (Optional, default to cache directory).

**Deprecated in irccd 2.1.0:**

  - **format-error**: Use `[format.history] error` instead,
  - **format-seen**: Use `[format.history] seen` instead,
  - **format-said**: Use `[format.history] said` instead,
  - **format-unknown**: Use `[format.history] unknown` instead,
  - **format-usage**: Use `[format.history] usage` instead.
