$ npm install snapdragon-capture-set
Plugin that adds a
.captureSet()method to snapdragon, for matching and capturing substrings that have anopenandclose, like braces, brackets, etc
Install with npm:
$ npm install --save snapdragon-capture-set
var Snapdragon = require('snapdragon');
var captureSet = require('snapdragon-capture-set');
var parser = new Snapdragon.Parser()
.use(captureSet())
.captureSet('brace', /^\{/, /^\}/)
.set('text', function() {
var pos = this.position();
var m = this.match(/^[^{}]/);
if (!m) return;
return pos({
type: 'text',
val: m[0]
});
});
var ast = parser.parse('a{b,{c,d},e}f');
console.log(ast.nodes[2]);
// Node {
// type: 'brace',
// nodes:
// [ Node { type: 'brace.open', val: '{', position: [Object] },
// Node { type: 'text', val: 'b', position: [Object] },
// Node { type: 'text', val: ',', position: [Object] },
// Node { type: 'brace', nodes: [Object], position: [Object] },
// Node { type: 'text', val: ',', position: [Object] },
// Node { type: 'text', val: 'e', position: [Object] },
// Node { type: 'brace.close', val: '}', position: [Object] } ],
// position: Position { start: { line: 1, column: 2 }, end: { line: 1, column: 3 } } }
Example
var Snapdragon = require('snapdragon');
var captureSet = require('snapdragon-capture-set');
// snapdragon
var snapdragon = new Snapdragon();
snapdragon.use(captureSet());
// parser
snapdragon.parser.use(captureSet());
