How can I get the specific scope name?
I can't find the one for csv file here.

I'm pretty sure that the scope for C++ files is source.cpp, not source.c++. I checked in the console (by running atom.workspace.getActiveTextEditor.getGrammar().scopeName) for multiple different extensions of C++ files, such as .c++ and .cpp and .cxx, and it showed the same scope for all of them, source.cpp.

I am missing the source for markdown file, also the github markdown

@8BitRobot how you do that? i try but get

Uncaught TypeError: atom.workspace.getActiveTextEditor.getGrammar is not a function
