Is it possible to set the syntax to use for a pattern using your User Preferences file?
A format like below would be great, where positive matches are additive to the extensions defined elsewhere.
"syntax_include_patterns": {
"JSON":
".jshintrc",
"*.sublime-project",
"*.sublime-workspace",
"*.sublime-settings"
],
"Shell":
".extra",
".bash_profile"
]
}
