Command-line tool for learning by repetition.

Inlrn you answer a series of self-prepared questions. You can choose between two modes. In thematch mode you type answer to a question, which is then checked against the correct answer. In thecards mode you flip between question and the correct answer, and decide yourself whether you knew it or not (just like flashcards).

lrn doesn't support spaced-repetition algorithms, schedules, categories, tags, styles etc. The final barrier between you and the thing you want to learn is removed. No last chance to procrastinate by tweaking knobs and whistles of the learning tool itself. What's left is to learn, learn, and repeat.

$ npm install --global lrn

Runlrn without arguments to see usage instructions:

$ lrn

As an example, to practice a deck inmatch mode:

$ lrn -m match decks/c.txt

Question and answer appear on separate lines, and are followed by a blank line:

Question 1Answer 1Question 2Answer 2...

The same deck can be practiced inmatch andcards modes.

It's recommended to keep your decks small so each can be studied in a single session. If you end up with a big deck you can generate smaller ones with:

$ split -l 72 big_deck.txt deck_

Just keep in mind that-l specifies number of lines, and each question and answer takes three lines in the deck file. If the learning material is hard, generate decks with fewer questions. If the material is easy, make the decks bigger.
