# Mibew Purge History plugin
It cleans up outdated dialogs.
## Installation
1. Get the archive with the plugin sources. You can download them from the [official site](https://mibew.org/plugins) or build the plugin from sources.
2. Untar/unzip the plugin's archive.
3. Put files of the plugins to the `<Mibew root>/plugins` folder.
4. (optional) Add plugins configs to "plugins" structure in "`<Mibew root>`/configs/config.yml". If the "plugins" stucture looks like `plugins: []` it will become:
```yaml
plugins:
"Mibew:PurgeHistory": # Plugin's configurations are described below
timeout: 172800
```
5. Navigate to "`<Mibew Base URL>`/operator/plugin" page and enable the plugin.
**Important**: The plugin uses cron tasks to perform cleaning so you need to make sure the Mibew's cron is and working.
## Plugin's configurations
The plugin can be configured with values in "`<Mibew root>`/configs/config.yml" file.
### config.timeout
Type: `Integer`
Default: `172800`
Time in seconds after which a dialog is considered outdated. The default value is 172800 seconds which is equal to two days.
## Build from sources
There are several actions one should do before use the latest version of the plugin from the repository:
1. Obtain a copy of the repository using `git clone`, download button, or another way.
2. Install [node.js](http://nodejs.org/) and [npm](https://www.npmjs.org/).
3. Install [Gulp](http://gulpjs.com/).
4. Install npm dependencies using `npm install`.
5. Run Gulp to build the sources using `gulp default`.
Finally `.tar.gz` and `.zip` archives of the ready-to-use Plugin will be available in `release` directory.
