AQL Syntax Highlighting

ANNIS Query Language (AQL) syntax highlighting for Obsidian code blocks.

Current release: v1.0.0

What Is ANNIS?

ANNIS (ANNotation of Information Structure) is an open-source search and visualization platform for richly annotated linguistic corpora.

• Official ANNIS repository: https://github.com/korpling/ANNIS
• ANNIS documentation homepage: http://corpus-tools.org/annis/

Features

• Registers an AQL CodeMirror mode for fenced code blocks.
• Supports token highlighting for strings, operators, metadata, node references, and node classes.
• Ships styling in styles.css, so highlighting works out of the box after install.
