# GitHub PRs Widget
<p align="center">
<a href="https://github.com/streetturtle/awesome-wm-widgets/labels/github-prs" target="_blank"><img alt="GitHub issues by-label" src="https://img.shields.io/github/issues/streetturtle/awesome-wm-widgets/github-prs"></a>
</p>
The widget shows the number of pull requests assigned to the user and when clicked shows additional information, such as
- author's name and avatar (opens user profile page when clicked);
- PR name (opens MR when clicked);
- name of the repository;
- when was created;
- number of comments;
![screenshot](./screenshots/screenshot1.png)
## Customization
It is possible to customize widget by providing a table with all or some of the following config parameters:
| Name | Default | Description |
|---|---|---|
| `reviewer` | Required | github user login |
## Installation
Install and setup [GitHub CLI](https://cli.github.com/)
Clone/download repo and use widget in **rc.lua**:
```lua
local github_prs_widget = require("awesome-wm-widgets.github-prs-widget")
...
s.mytasklist, -- Middle widget
{ -- Right widgets
layout = wibox.layout.fixed.horizontal,
...
github_prs_widget {
reviewer = 'streetturtle'
},
}
...
```
