I cannot find this anywhere and I swear I used to be able to very simply without much prying. Can anyone help me? Thanks. I would appreciate it. Also, does prettify support Batch?
You can find a table in the FAQ, under the header For which languages does it work?:
The comments in prettify.js are authoritative but the lexer should work on a number of languages including C and friends, Java, Python, Bash, SQL, HTML, XML, CSS, Javascript, Makefiles, and Rust. It works passably on Ruby, PHP, VB, and Awk and a decent subset of Perl and Ruby, but, because of commenting conventions, but doesn't work on Smalltalk.
Other languages are supported via extensions: ...
You can find the handlers, with their extensions in the loader directory
For the mapping from extensions to builtin languages, see the registerLangHandler calls in prettify.js
