An option remove console.warn from prismjs/components/index.js

[SukkaW]

Motivation

I am implementing a syntax highlight plugin for Hexo which requires runnning PrismJS inside Node.js.

I have use this approach (adopted from example provided by PrismJS website) to load supported languages that are not loaded by default:

const prismLoadLanguages = require('prismjs/components/');

However, when trying to load a language that doesn't supported by PrismJS will cause a console.warn output Language does not exist [language name].

Description

A silent option for not to print error message when loading a language that hasn't been supported by PrismJS could be helpful.

Alternatives

An API to get all current supported languages, maybe something like Prism.supportedLanguages() so that I could determine whether to use loadLanguages() or not.

My current solution is:

const prismComponents = require('prismjs/components.json');
const prismSupportedLanguages = Object.keys(prismComponents.languages);

[RunDevelopment]

For the time being, you could probably also just replace console.warn with a no-op function before you call loadLanguages and restore its function afterward.

(I made an issue to query supported languages (#2146).)
