How to know all syntax names available for a theme?


Hi guys,

I am making a grammar package for a custom logs file and as written in the Atom’s documentation, I am using the naming convention .
Nevertheless, I am fighting with Atom to know what’s the result for each of these names.

For example markup.bold.mypkg seems not being available for One light…

How can I see quickly which names are available ? Then I will restrict my grammar naming with those.

I wouldn’t like to add my own colors since it may be awful with other themes.

Thank you,


The quickest way to see which names you can use is to look at one of the core themes (such as one-light-syntax).
