Question

notice on sublime information​

Answer 1

Explanation:

Sublime Text uses property list (Plist) files to store syntax definitions. However, because editing XML files is a cumbersome task, we’ll use YAML instead and convert it to Plist format afterwards. This is where the PackageDev package (mentioned above) comes in.

Note

If you experience unexpected errors during this tutorial, chances are PackageDev or YAML is to blame. Don’t immediately think your problem is due to a bug in Sublime Text.

By all means, do edit the Plist files by hand if you prefer to work in XML, but always keep in mind their differing needs in regards to escape sequences, many XML tags etc.
