Select Preferences->Package Settings->SublimeLinter->Settings - User
and to add to it the following:
"sublimelinter_syntax_map":
{
"Python Django": "python",
"Ruby on Rails": "ruby",
"C++": "c"
"ExtendScript": "JavaScript"
}
and you should be all set. If it doesn't work, try changing JavaScript
to all lowercase - the docs are a little unclear as to which is correct.
