parser-cache

Cache and load parsers, similiar to consolidate.js engines.

Install

Install with npm

npm i parser-cache --save

Usage

var parsers = require('parser-cache');

API

Parsers

• options {Object}: Default options to use.

var Parsers = require('parser-cache');
var parsers = new Parsers();

.register

Register the given parser callback fn as ext. If ext is not given, the parser fn will be pushed into the default parser stack.

• ext {String}
• fn {Function|Object}: or options
• returns {Object} parsers: to enable chaining.

// Push the parser into the default stack
parsers.register(require('parser-front-matter'));
 
// Or push the parser into the `foo` stack
parsers.register('foo', require('parser-front-matter'));

.parse

Run a stack of async parsers for the given file. If file is an object with an ext property, then ext is used to get the parser stack. If ext doesn't have a stack, the default noop parser will be used.

• file {Object|String}: Either a string or an object.
• stack {Array}: Optionally pass an array of functions to use as parsers.
• options {Object}
• returns {Object}: Normalize file object.

var str = fs.readFileSync('some-file.md', 'utf8');
parsers.parse({ext: '.md', content: str}, function (err, file) {
  console.log(file);
});

Or, explicitly pass an array of parser functions as a section argument.

parsers.parse(file, [a, b, c], function (err, file) {
  console.log(file);
});

.parseSync

Run a stack of sync parsers for the given file. If file is an object with an ext property, then ext is used to get the parser stack. If ext doesn't have a stack, the default noop parser will be used.

• file {Object|String}: Either a string or an object.
• stack {Array}: Optionally pass an array of functions to use as parsers.
• options {Object}
• returns {Object}: Normalize file object.

var str = fs.readFileSync('some-file.md', 'utf8');
parsers.parseSync({ext: '.md', content: str});

Or, explicitly pass an array of parser functions as a section argument.

parsers.parseSync(file, [a, b, c]);

.parseStream

Run a stack of stream parsers for input files.

• stack {Array}: Optionally pass an array of functions to use as parsers.
• options {Object}
• returns {Stream}: Stream pipeline used to parse files in a stream.

gulp.src('path/to/files/*.md')
  .pipe(parsers.parseStream({ext: '.md'}))
  .pipe(gulp.dest('dist'));

Or, explicitly pass an array of parser functions as a section argument.

gulp.src('path/to/files/*.md')
  .pipe(parsers.parseStream([a, b, c], {ext: '.md'}))
  .pipe(gulp.dest('dist'));

.get

Return the parser stored by ext. If no ext is passed, the entire parsers is returned.

• ext {String}: The parser to get.
• returns {Object}: The specified parser.

parser.get('md')
// => { parse[function]}

.clear

Remove the parser stack for the given ext, or if no value is specified the entire parsers object is clear.

• ext {String}: The stack to remove.

Example:

parsers.clear()
