(text)-->(ast)-->(text)

gram.js is a collection of packages for working with the gram textual format for graph data.

You can parse .gram files into an AST.

Or, you can produce .gram files from an existing AST.

The AST is not a data model. But it does easily maps to a data model. For example see d3-gram.

How to gram in javascript

The 2 best places to start:

1. Parse from text using [[gram-parse]]
2. Build an AST by hand using [[gram-builder]]

All packages

• [[gram]] for general use
• [[gram-ast]] defines abstract syntax tree types
• [[gram-builder]] composes a valid AST
• [[gram-identity]] generates identity. (available as a unified plugin )
• [[gram-ops]] extracts features from the AST
• [[gram-parse]] processes text literal .gram into an AST. (available as a unified plugin )
• gram-preset-basic a unified preset for processing .gram files
• [[gram-stringify]] serializes AST back to text literal format (available as a unified plugin )
• [[gram-value]] enrich AST text literals with JS primitive or object values
