Keep track of changes of documents (halfway there)

[schollz]

I guess this could be done by storing diffs, or by storing a git internally or something...

Its actually easy:

package main

import (
    "fmt"

    "github.com/sergi/go-diff/diffmatchpatch"
)

func diffRebuildtexts(diffs []diffmatchpatch.Diff) []string {
    text := []string{"", ""}
    for _, myDiff := range diffs {
        if myDiff.Type != diffmatchpatch.DiffInsert {
            text[0] += myDiff.Text
        }
        if myDiff.Type != diffmatchpatch.DiffDelete {
            text[1] += myDiff.Text
        }
    }
    return text
}

func main() {
    dmp := diffmatchpatch.New()

    a := "tiger"
    b := "tigor"
    diffs := dmp.DiffMain(a, b, true)

    // Store as strings
    delta := dmp.DiffToDelta(diffs)
    fmt.Println(diffs)
    text1 := dmp.DiffText1(diffs)
    fmt.Println(text1, delta)

    // rebuild from strings
    seq1, _ := dmp.DiffFromDelta(text1, delta)
    fmt.Println(seq1)
    texts_linemode := diffRebuildtexts(seq1)
    latest := texts_linemode[len(texts_linemode)-1]

    fmt.Println(latest)

    // add something else
    newest := "tigre"
    diffs = dmp.DiffMain(latest, newest, true)
    // Store as strings
    delta = dmp.DiffToDelta(diffs)
    fmt.Println(diffs)
    text1 = dmp.DiffText1(diffs)
    fmt.Println(text1, delta)

    // rebuild from strings
    seq1, _ = dmp.DiffFromDelta(text1, delta)
    fmt.Println(seq1)
    texts_linemode = diffRebuildtexts(seq1)
    latest = texts_linemode[len(texts_linemode)-1]

    fmt.Println(latest)

}

Its halfway there...got the diffs in there. Just need to make a client side way of accessing them.

[schollz]

A subset of the diff documents should be shown to the user. Maybe all the documents that have a time between diffs of > 10 minutes? Or maybe a dynamic time setting that will allow fine/coarse adjustments. Or maybe just return the top 10 links to documents that have the greatest diffs between them.
