Zed HelixQL

Syntax highlighting for HelixDB's HelixQL query language in the Zed editor.

Activates on files with the .hx or .hql extension.

What it highlights

• Schema declarations (N::User, E::Follows, V::Embedding) and their From: / To: / Properties blocks
• QUERY definitions, parameters, FOR ... IN, RETURN
• Graph traversal steps: Out, In, OutE, InE, FromN, ToN, ShortestPath
• Creation steps: AddN, AddE, AddV, BatchAddV, SearchV
• Filtering / control: WHERE, EXISTS, RANGE, COUNT, UPDATE, DROP
• Boolean / comparison operators: AND, OR, GT, GTE, LT, LTE, EQ, NEQ
• Primitive types: String, Boolean, F32–F64, I8–I64, U8–U128, ID, Date
• Strings, numbers, booleans, NONE, NOW, INDEX, DEFAULT
• Operators (<-, =>, ::, .., !) and brackets

No language server — this is a highlight-only extension.

Install (dev / local)

1. Clone this repo.
2. In Zed: cmd-shift-p → "zed: install dev extension" → pick this directory.
3. Open any .hx / .hql file.

Validate query files locally

Mirrors the check that zed-industries/extensions CI runs at package time:

npm i -g tree-sitter-cli   # one-time
scripts/check.sh

Every .scm query is compiled against the pinned grammar from extension.toml using examples/sample.hx — invalid node references fail loudly before you push.

Install (from the extension store)

Once merged into zed-industries/extensions, you can find it in Zed's extensions panel as HelixQL.
