This release is a pre-release and may not be stable for production use.
tree-sitter-rdx
Tree-sitter grammar for RDX (Reactive Document eXpressions).
Provides syntax highlighting, code folding, and structural analysis for any editor that supports tree-sitter (Neovim, Helix, Zed, Emacs, etc.).
Parsed constructs
- Frontmatter (
---delimited YAML metadata) - Components — open/close tags, self-closing, nested
- Attributes — string, primitive, JSON, variable, boolean shorthand (including hyphenated names like
data-id) - Variable interpolation —
{$path.to.value} - Escape sequences —
\{$,\{{,\}},\{,\\ - Fenced code blocks with language tags (external scanner)
- Display math
$$...$$(external scanner) and inline math$...$ - Plain text and inline code
Markdown formatting (bold, italic, headings, lists) is intentionally treated as plain text — RDX components and variables are the tree-sitter grammar's concern, not Markdown structure.
Usage
Neovim
Add to your tree-sitter config:
require("nvim-treesitter.configs").setup({
ensure_installed = { "rdx" },
})
Helix
Add to languages.toml:
[[language]]
name = "rdx"
scope = "source.rdx"
file-types = ["rdx"]
roots = []
[language.auto-pairs]
[[grammar]]
name = "rdx"
source = { git = "https://github.com/rdx-lang/tree-sitter-rdx", rev = "main" }
Development
bun install
bunx tree-sitter generate
bunx tree-sitter test
Parse a file
bunx tree-sitter parse test/example.rdx
