Does whitespace matter in nginx conf files?

Question

When I import Flutter in Swift, Xcode is telling me No Such Module 'Flutter'

I have noticed there are Pods and Development Pods directories. Flutter resides in Development Pods.

Other modules in Pods are accessible.

Here is my Podfile:

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

platform :ios, '14.0'

project 'Runner', {
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
}

def flutter_root
  generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
  unless File.exist?(generated_xcode_build_settings_path)
    raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT\=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end

require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)

flutter_ios_podfile_setup

target 'Runner' do
  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
  
  pod 'TensorFlowLiteSwift/CoreML' #, '~> 0.0.1-nightly'

end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end
end

Any ideas?

Solution

It isn't removing all of your whitespace. It is reducing each chunk of whitespace to a single space. For most of your nginx.conf this won't hurt anything. If you have quoted strings with multiple spaces those will get changed too by the command above. You can check for that easily by greping for quotes in the template.

Rather than tweaking echo to preserve whitespace it might be easier to build your template as a heredoc in the script.

Getting rid of the extra whitespace could be useful to reduce memory footprints in an embedded environment, but unless you are severely resource constrained maintaining the formatting from template to actual configuration will make debugging much more pleasant.

I ended up just using confd, much better than this hack, but chicks did answer the question at hand I guess

What are the contents of pod file?

[Fred]

@Biclops added podfile

[Christian Grabowski]

Sorry I should clarify, and will, I meant the whitespace in my indentation.

[Biclops]

Another guess is to blow out the pod file itself, and run the command that generated the podfile. Did you use flutter build ios or flutter build ipa to make the podfile?

[Fred]

I did something similar to your shot in the dark and it worked. The Podfile was created by flutter. Thank you for your service.

Did you guys just solve this problem: github.com/flutter/flutter/issues/92337 ??
