	#!/usr/bin/env ruby

	projects = %w[CSV Caboodle Transcript Recipes Mockingbird Bindings WhatsYourFine Typewriter Specify Posit Braille Handsy]

	# a regular expression to identify the existing header format
	# in this case, I had been using the format from the Xcode file templates
	existing_format = /\/\/\n\/\/ .\n\/\/ .\n\/\/\n\/\/.\n\/\/.\n\/\/\n/

	# the new format to replace the old
	# in my case, I didn't want to include file names or the project name,

ryanmasondavies / pods.rb

Created April 21, 2013 10:09

Install pods in multiple projects.

	top = Dir.pwd
	Dir["*//Podfile"].each do \|f\|
	dir = File.dirname(f)
	Dir.chdir(dir)
	puts "Installing pods for #{dir} ..."
	system "pod install --verbose"
	Dir.chdir top
	end

ryanmasondavies / prefix_changer.rb

Last active December 21, 2015 22:59

Ruby script to update file prefixes recursively. Useful to quickly change filenames to match a class prefix change in an Xcode project.

	#!/usr/bin/env ruby

	class String
	def starts_with?(prefix)
	prefix = prefix.to_s
	self[0, prefix.length] == prefix
	end
	end

	old = 'RJD' # old prefix

ryanmasondavies / svn-revert-all

Last active December 21, 2015 22:59

Remove all changes from `svn status`

svn status --no-ignore | grep -E '(^\?)|(^\I)' | sed -e 's/^. *//' | sed -e 's/\(.*\)/"\1"/' | xargs rm -rf

ryanmasondavies / svn_prefix_changer.rb

Created August 29, 2013 15:41

Ruby script to update file prefixes recursively when working with a Subversion repository. Useful to quickly change filenames to match a class prefix change in a Subversion Xcode project.

	#!/usr/bin/env ruby

	class String
	def starts_with?(prefix)
	prefix = prefix.to_s
	self[0, prefix.length] == prefix
	end
	end

	old = 'RJD' # old prefix

ryanmasondavies / MigrateCoreDataStoreType.m

Created December 27, 2013 17:17

Opens up a Core Data store using a custom atomic type and migrates the store to another type. This would be useful for importing data, e.g for opening up a CSV file using a custom type and converting it an SQLite store. However, while this is easy and makes use of in-house components, it introduces more steps than are necessary for importing dat…

	// grab the model:
	NSURL *modelURL = [[NSBundle mainBundle] URLForResource:@"StoreMigration" withExtension:@"momd"];
	NSManagedObjectModel *managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL];

	// create a new example store type:
	NSPersistentStoreCoordinator *csvCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:managedObjectModel];
	csvCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:managedObjectModel];
	if (![csvCoordinator addPersistentStoreWithType:[SMGCSVStore type] configuration:nil URL:csvStoreURL options:nil error:&error]) {
	NSLog(@"Couldn't add store: %@", [error localizedDescription]);
	abort();

ryanmasondavies / EiffelTowerRegionMonitoring.m

Last active August 29, 2015 13:57

	CLLocationManager *locationManager = [[CLLocationManager alloc] init];
	[locationManager setDelegate:self];
	[locationManager setDesiredAccuracy:kCLLocationAccuracyHundredMeters];
	[self setLocationManager:locationManager];

	// ...

	CLLocationCoordinate2D eiffelTowerCoordinates = CLLocationCoordinate2DMake(48.858093, 2.294694);
	CLLocationDistance radius = 20; // 20 meters
	CLRegion *region = [[CLRegion alloc] initCircularRegionWithCenter:eiffelTowerCoordinates radius:20.0 identifier:@"Eiffel Tower"];
