danger-xcode_warnings

A Danger plugin to format and show warnings from xcodebuild.

• Extract the compiler and linker warnings from the build log and format them for Danger
  • Both xcodebuild and xcpretty format are supported
• Gather the build timing summary and show

gem install danger-xcode_warnings

Or using Bundler,

gem 'danger-xcode_warnings'

Firstly, collect the log from xcodebuild.

xcodebuild clean build -workspace ... > build.log
# If you want to show the log with xcpretty
xcodebuild clean build -workspace ... | tee build.log | xcpretty

And then, call analyze_file method in your Dangerfile to analyze the build log,

xcode_warnings.analyze_file 'build.log'

with some shell scripts with your CI, like:

bundle install
bundle exec danger

If you want to analyze the xcpretty log, you MUST set the use_xcpretty flag in your Dangerfile:

xcode_warnings.use_xcpretty = true
xcode_warnings.analyze_file 'build.log'

Your build script for CI should be like,

xcodebuild clean build -workspace ... | xcpretty > build.log

To show linker warnings, set the show_linker_warnings to true before analyzing the log:

xcode_warnings.show_linker_warnings = true
xcode_warnings.analyze_file 'build.log'

To gather the build timing summary, you have to add -showBuildTimingSummary option to your build script:

xcodebuild clean build -workspace ... -showBuildTimingSummary > build.log

Then, set the build_timing_summary flag to true.

xcode_warnings.build_timing_summary = true
xcode_warnings.analyze_file 'build.log'
