custom syntax for code block

I’m trying making something like this

```ttt
some code without syntax highlight
```

and want the code to be highlighted just like well-known language syntax

```javascript
some code with syntax highlight
```

How can i do it?

I had checked the r markdown specification and had learn about the knitr engine. And I found these problems:

• The language-markdown package works with the {javascript } code block, but I have to insert a whitespace between javascript and }. It seems a little bug.
• In R markdown, in the '''{r } '''(for convenience, I’m using ’ to replace in this comment) pattern, the prefix{rshould be a keyword indicates that the R markdown parser should treat this "code block" as an "code chunk". The language used inside the chunk should be specified by theengineoption. For example,‘’‘{r engine=“javascript”} ‘’‘indicates that this code chunk contains javascript code. This is doced [here](http://yihui.name/knitr/demo/engines/). Any code chunk beginning label replaces therin’’'{r } ‘’'with other language name, should be an shorthand or theengineoption. doced [here](http://rmarkdown.rstudio.com/authoring_knitr_engines.html). Language-markdown package seems not supports theengine` option grammar.

That depends on the language ; )

The source.languagename you are referring too is the base scope that these grammars use. Atom is essentially a webpage, and this base scope is the css class given to a line that contains code from that particular language. The thing is, it differs for a number of languages.

The easiest way to find this scope is to open the main grammar file for a language (grammars/language-markdown.json in the case of this package) and (usually) near the top of the file you’ll see an item named scopeName, and that’s the value you are looking for that you’ll need for the include section of the fenced-code bit. The scopeName for language-latex would be text.tex.latex.

Latex will be added in an upcoming version though. I’ve recently added support for inline math, and it’s part of that. If you need help with any other languages, feel free to open a new issue, point me to the language-packages, and it should be in the next version.
