slate-instant-replace

A Slate plugin that gives you full power on the last word your user typed.

⚠️ This package is compatible with <= slate@0.47, please refer to this issue if you are working on >= slate@0.50 ⚠️

Why ?

I was looking at some plugin to automatically replace some text at the very same moment that you press the key that completes the word you want to replace. There is already a SlateJS auto replace plugin, however you need to specify a key to trigger the replacement and this key cannot be a part of the replaced text.

How ?

This plugin applies your transformations every time you write a new letter and has no opinion on the changes you make to the SlateJS's editor instance. Your transformation functions will receive as arguments the editor instance and the last word write and the rest is up to you !

Install

npm install --save slate-instant-replace
yarn add slate-instant-replace

Usage

import InstantReplace from "slate-instant-replace";
import { Editor } from "slate-react";

const YourFunction = (editor, lastWord) => {
  ...
}

// Add the plugin to your set of plugins...
const plugins = [InstantReplace(YourFunction)];

// And later pass it into the Slate editor...
<Editor
  ...
  plugins={plugins}
/>

Multiple transforms

You can also apply a set of multiple replacement functions, in that case the argument needs to be an array of functions like (in which case the function will be applied in the same order you write them):

const plugins = [InstantReplace([YourFunction1, YourFunction2, YourFunction3])];

Options

Option	Type	Description
transform	Function ArrayOf(Function)	The transforms to apply to the change object each time a letter is pressed. If an array is passed, the functions will be applied from the first element of the array to the last.

Commands and queries

Additionally this plugins exposes the follow commands and queries if you want to reuse them for your other plugins:

Name	Type	Description
getSelection	query	Returns the current selection.
getCurrentWordOffset	query	Returns the offset of the current word in the node.
getLastWord	query	Returns the last word using as a reference the current anchor position.
getPreviousNode	query	Returns the previous node to the one currently focused.
isFirstCharOfNode	query	Returns true if the anchor is at position 0 of the current node.
focusPreviousInlineNode	command	Focuses the previous Inline node.

Commands and queries get automatically attached to the editor instance. This means you can use them like this:

editor.getSelection();
editor.focusPreviousInlineNode();
