Create a new plugin Tools > Developer > New Plugin...
Insert this into:
import sublime, sublime_plugin class EverythingIsPowerShell(sublime_plugin.EventListener): def on_new(self, view): view.set_syntax_file('Packages/PowerShell/Support/PowershellSyntax.tmLanguage')
Save and name it NewTabSyntax.py . New tabs will now be by default in Powershell.
You can change the syntax to whatever you prefer. To find the "path" of a particular syntax, simply open the file for that syntax, open the console (" View > Show Console ) and enter:
view.settings().get('syntax')
