Emacs major mode for Yasnippet snippets using tree-sitter

Snippet major mode using tree-sitter

This package provides a major-mode for yasnippet snippets using the tree-sitter grammar from tree-sitter-yasnippet.

Features:

• font-locking
• basic indentation inside elisp code regions
• some interactive commands to move between fields and increment field indices.
• completion-at-point: for elisp in code regions and for snippet headers
• elisp xref in code regions

WIP: Use elisp parser in elisp code regions.
