Get file syntax selection in sublime text 3 plugin

I have a very small plugin to open a perl file module starting from the use statement. It's really basic and it just replaces '::' with '/' and then if the file exists in one of the paths specified in PERL5LIB, it opens it. I want it to run only when the open file syntax is selected as perl. Is there any API to get that information? This is the code that I have now:

class OpenPerlModule(sublime_plugin.TextCommand):
    def run(self, edit=None, url=None):
        perl_file = url.replace("::", "/")
        perl_dirs = os.environ.get('PERL5LIB')
        for perl_dir in perl_dirs.split(':'):
            if (os.path.exists(perl_dir + '/' + perl_file + '.pm')):
                self.view.window().open_file(perl_dir + '/' + perl_file + '.pm')
                return

(The OS is Ubuntu)

Aside from self.view.settings().get("syntax") as described in Allen Bargi's answer, you could also get the scope for the current cursor position and check for source.perl in it:

import sublime_plugin

class FindScopeCommand(sublime_plugin.TextCommand):
    def run(self, edit):
        # `sel()` returns a list of Regions that are selected. 
        # Grab the beginning point of the first Region in the list.
        first_point = self.view.sel()[0].a
        # now, get the full scope name for that point
        scope = self.view.scope_name(first_point)
        if "source.perl" in scope:
            print("You're using Perl. Yay!")
        else:
            print("Why don't you love Perl?")

Here is the code snippet you're looking for

self.view.settings().get("syntax")

You should check whether it's a syntax related to Perl or not. I suggest something like this: 

syntax = self.view.settings().get("syntax")
syntax.endswith("Perl.tmLanguage") or syntax.endswith("Perl.sublime-syntax")

The second or clause is to cover the new syntax that's introduced in >=3080
