@gram-data/gram-ops

Utility operations for extracting path features.

How to gram-ops

Install:

npm install @gram-data/gram-ops

Build a path

Use [[gram-builder]] to create a path.

import { node, edge } from '@gram-data/gram-builder';

const left = node('a');
const right = node('b');
const path = edge([left, right], 'right');

Extract features from the path

Extract a node list:

import { nodes } from '@gram-data/gram-ops';

const ns:GramPath[] = nodes(path); 

Extract an edge list:

import { nodes } from '@gram-data/gram-ops';

const es:GramPath[] = edges(path); 
console.log(ns.map(n => stringify(n)).join()); // (a),(b)

Next Steps

• Transform to js objects using [[gram-value]]
• Write back to a string using [[gram-stringify]]
• Introspect the AST using [[gram-ast]]
