Satya

Tree immutable undo/redo stack using immer RFC6902 style patches

const satya = new Satya(typescriptSchema);
satya.update([
  {
    type: "node",
    operation: {
      path: [],
      op: "replace",
      value: sourceFile

      path: ["statements", 0],
      op: "add",
      value: {}
    }
  }
]);

    type: "metadata",
    operation: {
      path: ["statements", 0, SatyaMetaSym, "general", "expanded"],
      op: "add",
      value: true
    }
  }

const meta1 = satya.readMetaData(
  ((satya.state as ts.SourceFile)
    .statements[0] as unknown) as ts.VariableDeclaration,
  "general",

expect(meta1).toBe(true);

##TODO

• compute reverse for "replace" | "remove" | "add"
• implement helper functions for undo/redo
