Utils for document transformation

removeParentNodeOfType(nodeType: NodeType | [NodeType]) → fn(tr: Transaction) → Transaction

  removeParentNodeOfType(schema.nodes.table)(tr)
);
```
replaceParentNodeOfType(nodeType: NodeType | [NodeType], content: ProseMirrorNode | Fragment) → fn(tr: Transaction) → Transaction

```
const node = schema.nodes.paragraph.createChecked({}, schema.text('new'));

dispatch(
 replaceParentNodeOfType(schema.nodes.table, node)(tr)
);
```
removeSelectedNode(tr: Transaction) → Transaction
Returns a new transaction that removes selected node. It will return an original transaction if current selection is not a NodeSelection.

dispatch(
  removeSelectedNode(tr)
);
```
replaceSelectedNode(content: ProseMirrorNode | ProseMirrorFragment) → fn(tr: Transaction) → Transaction

dispatch(
  replaceSelectedNode(node)(tr)

canInsert($pos: ResolvedPos, content: ProseMirrorNode | Fragment) → boolean
Checks if a given content can be inserted at the given $pos

if (canInsert($from, node)) {
  // ...
}

safeInsert(content: ProseMirrorNode | Fragment, position: ?number, tryToReplace: ?boolean) → fn(tr: Transaction) → Transaction
Returns a new transaction that inserts a given content at the current cursor position, or at a given position, if it is allowed by schema. If schema restricts such nesting, it will try to find an appropriate place for a given node in the document, looping through parent nodes up until the root document node. If tryToReplace is true and current selection is a NodeSelection, it will replace selected node with inserted content if its allowed by schema. If cursor is inside of an empty paragraph, it will try to replace that paragraph with the given content. If insertion is successful and inserted node has content, it will set cursor inside of that content. It will return an original transaction if the place for insertion hasn't been found.
```
const node = schema.nodes.extension.createChecked({});
dispatch(
  safeInsert(node)(tr)
);
```
setParentNodeMarkup(nodeType: NodeType | [NodeType], type: ?NodeType | null, attrs: ?Object | null, marks: ?[Mark]) → fn(tr: Transaction) → Transaction

selectParentNodeOfType(nodeType: NodeType | [NodeType]) → fn(tr: Transaction) → Transaction
Returns a new transaction that sets a NodeSelection on a parent node of a given nodeType.
```
dispatch(
  selectParentNodeOfType([tableCell, tableHeader])(state.tr)
);
```
removeNodeBefore(tr: Transaction) → Transaction
Returns a new transaction that deletes previous node.
```
dispatch(
  removeNodeBefore(state.tr)
);
```
setTextSelection(position: number, dir: ?number = 1) → fn(tr: Transaction) → Transaction
Returns a new transaction that tries to find a valid cursor selection starting at the given position and searching back if dir is negative, and forward if positive. If a valid cursor position hasn't been found, it will return the original transaction.
```
dispatch(
  setTextSelection(5)(tr)
);
```
