Heads up! API Changes in 0.4.0

Install

Install with npm

$ npm i lang-map --save

Usage

var map = require('lang-map');

Get language by extension

Returns the language that is associated with the given file extension (with or without .):

var map = require('lang-map');

map.languages('coffee');
//=> [ 'coffeescript' ]
map.languages('handlebars');
//=> [ 'handlebars' ]
map.languages('hbs');
//=> [ 'handlebars' ]
map.languages('javascript');
//=> [ 'javascript' ]
map.languages('js');
//=> [ 'javascript' ]
map.languages('md');
//=> [ 'markdown' ]
map.languages('mkdown');
//=> [ 'markdown' ]

Why is an array of languages returned?

In some (rare) cases an extension maps to multiple languages.

map.languages('h');
//=> [ 'c', 'c++', 'objective-c' ]

Get extensions by language

Returns the list of file extensions associated with the given language:

var map = require('lang-map');

map.extensions('coffee');
//=> [ 'coffee', '_coffee', 'cjsx', 'cson', 'iced' ]
map.extensions('hbs');
//=> [ 'handlebars', 'hbs' ]
map.extensions('markdown');
//=> [ 'md', 'markdown', 'mkd', 'mkdn', 'mkdown', 'ron' ]
map.extensions('md');
//=> [ 'md', 'markdown', 'mkd', 'mkdn', 'mkdown', 'ron' ]
map.extensions('c');
//=> [ 'c', 'cats', 'h', 'idc', 'w' ]
