• Support lines wrapping
• Support syntax highlighting
• Can ignore whitespace
• Can ignore case
• Custom input history
• Blocks, words and chars counter
• Works in SvelteKit & TypeScript

npm i @getjoystick/mismerge-core

<script>
	import { MisMerge3 } from '@getjoystick/mismerge-core';
	// Core styles, required for the editor to work properly
	import '@getjoystick/mismerge-core/styles.css';

	import '@getjoystick/mismerge-core/light.css';
	// Or  '@getjoystick/mismerge-core/dark.css';

	let lhs = 'foo';
	let ctr = 'bar';
	let rhs = 'baz';
</script>

<!-- Left-hand side and right-hand side constant text -->
<MisMerge3 {lhs} {rhs} bind:ctr />

<!-- All sides editable -->
<MisMerge3 bind:lhs bind:ctr bind:rhs lhsEditable rhsEditable >

<style>
  :global(.mismerge) {
    font-family: monospace;
    min-height: 600px;
  }
</style>

You need to provide your own syntax highlighter. Example and demo using Shiki-JS. The highlighter can be either sync or async.

<script>
	import { codeToHtml } from 'shiki';
	// ...

	const highlight = async (text: string) =>
		await codeToHtml(text, {
			lang: 'js',
			theme: 'min-dark'
		});
</script>

<MisMerge3 ... {highlight} />

<script>
	import { DefaultDarkColors } from '@getjoystick/mismerge-core';
	// ...
</script>

<MisMerge3 ... colors={DefaultDarkColors} />

If you want to customize the editor styles, you can copy the default light or dark theme and adapt it to your need.

Here is a basic explanation of how the the rendered html looks like:

<div class="mismerge">
	<div>
		<!-- Main -->
		<div class="msm__main">
			<!-- View -->
			<div class="msm__view">
				<!-- Content -->
				<div class="msm__view-content">
					<!-- Blocks wrapper -->
					<div class="msm__wrapper">
						<!-- Blocks -->
						<div data-component-id="abcdefgh" class="msm__block block-type">
							<!-- Lines -->
							<div class="msm__line">
								<!-- ... -->
							</div>
							<!-- ... -->
						</div>
						<!-- ... -->
					</div>

					<!-- Highlight overlay -->
					<div class="msm__highlight-overlay">
						<!-- ... -->
					</div>

					<!-- Input -->
					<textarea />
				</div>

				<!-- Side panel -->
				<div class="msm__side-panel">
					<!-- ... -->
				</div>
			</div>
		</div>
	</div>

	<!-- Footer -->
	<div class="msm__footer">
		<!-- ... -->
	</div>
</div>
