[![Build Status](https://travis-ci.org/diogot/danger-xcode_summary.svg?branch=master)](https://travis-ci.org/diogot/danger-xcode_summary)

A [Danger](http://danger.systems) plugin that shows all build errors, warnings and unit tests results generated from `xcodebuild`.

You need to use [xcpretty](https://github.com/supermarin/xcpretty) with 
[xcpretty-json-formatter](https://github.com/marcelofabri/xcpretty-json-formatter) 
to generate a JSON file that this plugin can read.

**Using [danger-swift](https://github.com/danger/swift)**? You may want to take a look at [danger-swift-xcodesummary](https://github.com/f-meloni/danger-swift-xcodesummary).

## Installation

Add this line to your Gemfile:

```ruby
gem 'danger-xcode_summary'
```

## Usage

Just add this line to your `Dangerfile`:

```ruby
xcode_summary.report 'xcodebuild.json'
```

You can also ignore warnings from certain files by setting `ignored_files`: 
Warning: `ignored_files` patterns applied on relative paths.  

```ruby
# Ignoring warnings from Pods
xcode_summary.ignored_files = 'Pods/**'

# Ignoring specific warnings
xcode_summary.ignored_results { |result|
  result.message.start_with? 'ld' # Ignore ld_warnings
}

xcode_summary.report 'xcodebuild.json'
```

You can use `ignores_warnings` to supress warnings and shows only errors.

```ruby
xcode_summary.ignores_warnings = true
```

You can use `inline_mode`.
When this value is enabled, each warnings and errors are commented on each lines.

```ruby
# Comment on each lines
xcode_summary.inline_mode = true
xcode_summary.report 'xcodebuild.json'
```

You can get warning and error number by calling `warning_error_count`. The return will be a JSON string contains warning and error count, e.g {"warnings":1,"errors":3}:

```ruby
result = xcode_summary.warning_error_count 'xcodebuild.json'
```
