json0/ot-text string edits to ot-text-unicode json1 string edits

[curran]

A function that does this conversion would be great.

Has it been done somewhere already? Or is a completely new implementation required?

Need to pay attention to modification:

• Need to put text --> text-unicode
• require ot-json1 and use these methods: type, removeOp, insertOp, replaceOp, editOp

const { type, removeOp, insertOp, replaceOp, editOp } = require('ot-json1');

...
...

function json0to1(json0Op) {
  // JSON0 ops are a list of {p: path, operation}.
  // See https://github.com/ottypes/json0#summary-of-operations
  return json0Op.map(c => {
    ...
    else if (c.t) return c.t === 'text0' ? editOp(c.p, 'text-unicode', text0ToText(c.o)) : editOp(c.p, c.t, c.o)
    // Note: Using the old text type here because thats what json0 uses.
    // You will have to register it if you want to use it.
    else if (c.si != null) return editOp(c.p.slice(0, -1), 'text-unicode', textOpAt(c.p[c.p.length - 1], c.si))
    else if (c.sd != null) return editOp(c.p.slice(0, -1), 'text-unicode', textOpAt(c.p[c.p.length - 1], { d: c.sd.length }))
    ...
    }).reduce(type.compose, null)
    ...

Test the final effect：

const json0to1 = require('./index')
console.log(json0to1([{ "p": ["content", 0], "si": "g" }]))
// [ 'content', { es: [ 'g' ] } ]
