I'm writing an ebook using Pandoc for a proprietary programming language, similar to SQL. I found out how to change the color by adding -s --highlight-style haddock when creating the book, but there are about 50 or so keywords that are missing. I noticed, reading through other posts, that you can change the color of the scheme, but I haven't found any way to actually create a new language with all the SQL keywords + my new ones or to just update the SQL language with the new keywords I need.
How can I create either a new language or update the SQL language to add my new keywords?
