ryanmasondavies / header_substituter.rb
Created April 12, 2013 12:31
A Ruby script for replacing header files in multiple projects at once.
#!/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 / 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 / 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();
