forgetful¶ ↑
A minimal command-line app implementing the SuperMemo 2 algorithm.
The SuperMemo algorithm is designed to refresh your memory at intervals based on how well you remembered something.
Put question-answer pairs in a file. Everyday, feed the file to forgetful and it will quiz you on what you need to remember today. Based on your self-evaluation, forgetful will reschedule at an appropriate time in the future.
Install¶ ↑
gem install forgetful
Usage¶ ↑
forgetful filename.csv [more filenames]
The CSV files are formatted very simply:
question,answer
The interaction goes as follow:
forgetful: shows question you: press enter forgetful: shows answer forgetful: asks for self-evaluation you: type a number, press enter
You will be asked all of today’s questions. After you will be asked, again, the questions for which you scored less than 4.
Self-evaluation values:
5 - perfect response 4 - correct response after a hesitation 3 - correct response recalled with serious difficulty 2 - incorrect response; where the correct one seemed easy to recall 1 - incorrect response; the correct one remembered 0 - complete blackout.
WARNING: Statistics are written back to the input file. This is a feature. Put your CSV files under source control to keep a history.
Enjoy!
