Choose how to parse a file manually

[xcpky]

Normally helix parse a file based on the file extensions, like .cpp. Can we specify the way helix treat a file on our own? When I am viewing the source code of STL in C++, the file has no extension thus making the syntax highlight fail. Can I make helix treat it as a cpp file?

You can use the :set-language (:lang for short) command to tell helix which language you'd like to use for syntax highlight and LSP on a buffer.
