TypeError: grammar is undefined

[AlphaBeta1906]

Why i got this error?i trying to dynamically hiligth code in prism with this code :

Prism.highlight(paste.code, Prism.languages[paste.language], paste.language)
// paste.language = name of language i want to highlight

it only worked for html,css,js and python(as far as i know),but when try to hilight for example rust code i got error,i already try import all error languages but still not working except when i use it individually e.g :

Prism.highlight(paste.code, Prism.languages.rust, paste.language)

so how to solve TypeError: grammar is undefined and use all languages in prism?
I use the mithril framework which uses vanilla javascript

A stack trace would have been nice. My guess is that the error occurs here. This means that the languages isn't loaded.

It seems that you also changed something else when you changed Prism.languages[paste.language] -> Prism.languages.rust. Whatever that something was, it loaded all languages (or at least Rust) correctly.

While the incorrect language loading probably isn't Prism's fault, the very non-descriptive error message is. I'll add a better error. (see #3311)

Btw, the reason why HTML, CSS, and JS will always work is that those 3 languages (plus one util language) are always loaded by default. Prism was originally a very web-languages-focused highlighter.

So how to get prismjs to load all languages? and about the rust code that work i import rust component from prismjs(import 'prismjs/components/prism-rust';),but even though already import the language component i still cant use Prism.languages[paste.language],so basically i need to use it individually.

That depends on your JS environment. On NodeJS, you can use loadLanguages() to load all languages. With webpack/any bundler, our babel plugin will handle loading all languages for you. Those are currently the only 2 ways to easily load all languages.

As a last resort, if none of those solutions fits your needs, then you could also download a bundle from our download page.
