# This script reads the filespecs in the current directory, collects names of files | |
# in the default screenshot file name format, converts the names to lower case | |
# with spaces converted to hyphens, and removes the "at" to produce a command line friendly filespec; | |
# for example, "Screenshot 2024-02-18 at 21.06.31.pdf" becomes "screenshot-2024-02-18--21.06.31.pdf". | |
# | |
# It ignores but preserves the extensions, so if you have changed the screenshot file type with, e.g.: | |
# defaults write com.apple.screencapture type pdf && killall SystemUIServer | |
# then it will rename those PDF files too. |

# Any module (not class) that includes SemanticLogger::Loggable must also implement an | |
# `included` method that gets the including class to also include SemanticLogger::Loggable. | |
# This is because the module's instance method `logger`, when it becomes part of the including | |
# class, will look for `self.class.logger` when called, and `self` will evaluate to the instance | |
# of the class and not the module. Having the class include `Loggable` will cause a class method | |
# `logger` to be created so that this will work. | |
# | |
# This method returns the modules that have included Loggable but do not have an `included` | |
# method implementation. This is an imperfect test since we are not testing the content of that | |
# implementation, but I don't know a better way. |
