Spaced repetition system for OmniOutliner 3 Thread Tools Search this Thread Display Modes
Prev Previous Post   Next Post Next
I'm sure this could be accomplished a lot more efficiently, but here's my attempt to add spaced repetition functionality to OmniOutliner 3. The goal is more efficient memorization using the SM-2/SuperMemo algorithm. (I hope I implemented the formula correctly). Flashcard programs like Anki and Mnemosyne are great, but it's tough to see the context of what you're learning, and in law context is very important. Using OmniOutliner, the row text can serve as a question and the note text as the answer. Columns 3, 4, 5, and 6 are used to store the information about past and future repetitions.





Code:
tell application "OmniOutliner"
    -- columns:
    -- 1 is checkbox (unused)
    -- 2 is for content (questions in the row; answers as comments)
    -- 3 is quality
    -- 4 is due
    -- 5 is numReps
    -- 6 is EF  
    set baseEaseFactor to 1.3
    set i to value of cell 5 of selected row of front document -- number of repetitions thus far
    set q to value of cell 3 of selected row of front document -- Get quality #
    -- Set existing easiness factor...
    if value of cell 6 of selected row of front document contains "" then
        set value of cell 6 of selected row of front document to baseEaseFactor as text
        set oldEF to baseEaseFactor
    else
        set oldEF to value of cell 6 of selected row of front document -- Get oldEF
    end if
    -- If there have been no reps:
    if i as integer is equal to 0 then
        set nextDue to do shell script "date -v+0d +%Y-%m-%d" as string
        set value of cell 4 of selected row of front document to nextDue as string
        set value of cell 5 of selected row of front document to "1" as string
        set value of cell 6 of selected row of front document to baseEaseFactor as string
        return
        -- If there have been 2 reps:
    else if i as integer is equal to 1 then
        set i to i + 1
        set value of cell 5 of selected row of front document to i as string
        set dueCellValue to do shell script "date -v+1d +%Y-%m-%d" as string
        set value of cell 4 of selected row of front document to dueCellValue as string
        return
    else if i as integer is equal to 2 then
        set nextDue to do shell script "date -v+6d +%Y-%m-%d" as string
        set value of cell 4 of selected row of front document to nextDue as string
        set value of cell 5 of selected row of front document to "3" as string
        set value of cell 6 of selected row of front document to baseEaseFactor as string
        return
    else -- all other numbers
        set value of cell 5 of selected row of front document to i + 1 as string
        set newEF to oldEF - 0.8 + 0.28 * q - 0.02 * q * q
        if newEF is less than 1.3 then
            set newEF to 1.3
        end if
        if newEF is greater than or equal to 2.5 then
            set newEF to 2.5
        end if
        set value of cell 6 of selected row of front document to newEF as string
        if q > 0 then
            set nextDue to (i * (i - 1) * newEF) as integer
            set dueCellValue to do shell script "date -v+" & nextDue & "d +%Y-%m-%d"
            set value of cell 4 of selected row of front document to dueCellValue as string
            set i to i + 1
            set value of cell 5 of selected row of front document to i as string
        else
            set nextDue to do shell script "date -v+0d +%Y-%m-%d" as string
            set value of cell 4 of selected row of front document to nextDue as string
            set value of cell 5 of selected row of front document to "0" as string
        end if
    end if
end tell
I've got more written up about this on my site, along with simpler spaced repetition routines for some other software (VoodooPad and EagleFiler).
