Error tracking and reporting to Rollbar.

A [Rollbar](https://rollbar.com) reporter for [Tower](https://github.com/mimiquate/tower) error handler.

## Installation

The package can be installed by adding `tower_rollbar` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:tower_rollbar, "~> 0.6.6"}
  ]
end
```

## Setup

### Option A: Automated setup

```sh
$ mix tower_rollbar.install
```

### Option B: Manual setup

Ask `Tower` to use the `TowerRollbar` reporter.

```elixir
# config/config.exs

config(
  :tower,
  :reporters,
  [
    # along any other possible reporters
    TowerRollbar
  ]
)
```

And configure `:tower_rollbar`.

```elixir
# config/runtime.exs

if config_env() == :prod do
  config :tower_rollbar,
    access_token: System.get_env("ROLLBAR_SERVER_ACCESS_TOKEN"),
    environment: System.get_env("DEPLOYMENT_ENV", to_string(config_env()))
end
```

## Reporting

That's it.
There's no extra source code needed to get reports in Rollbar UI.

Tower will automatically report any errors (exceptions, throws or abnormal exits) occurring in your application.
That includes errors in any plug call (including Phoenix), Oban jobs, async task or any other Elixir process.

Some HTTP request data will automatically be included in the report if a `Plug.Conn` if available when Tower handles
the error, e.g. when an exception occurs in a web request.

### Manual reporting

You can manually report errors just by informing `Tower` about any manually handled errors, throws or abnormal exits.

```elixir
try do
  # possibly crashing code
rescue
  exception ->
    Tower.report_exception(exception, __STACKTRACE__)
end
```
