svelte-mode

• Emacs major mode specifically designed for .svelte files, based on mhtml-mode
• Requires Emacs version 26 or higher
• Supports Svelte directives and blocks
• Integrates with other modes for different languages within Svelte components:
  • typescript-mode for <script lang="ts">
  • sass-mode for <style lang="sass">
  • pug-mode for <template lang="pug">
  • coffee-mode for <script lang="coffee">
• Works with emmet-mode for HTML/CSS expansion
• Includes JavaScript/CSS as submode in html-mode

Customization options:

• svelte-basic-offset: Controls basic indentation level (defaults to sgml-basic-offset)
• svelte-tag-relative-indent: Whether script/style bodies indent to their tags (default: true)
• svelte-display-submode-name: Shows active submode in status line (default: false)

Special feature:
Includes a configuration workaround for case-sensitive tag handling, particularly useful for Svelte components that share names with HTML tags (like Link components).
