how catch sublime text exceptions on python interpreter?

this migrated https://github.com/sublimetextissues/core/issues/1359

i trying catch exception:

    try:          print( 'running' )         sublime.active_window().run_command( "side_bar_update_sync" )         isnotsyncedsidebarenabled = false         print( 'running this' )      except baseexception:          isnotsyncedsidebarenabled = true         print( 'running also' ) 

but when ran, not catches it. not matter if try within typeerror, exception or baseexception classes. below full exception output.

reloading plugin sublimedefaultsyntax.default_syntax read_pref_async!!!!     updateissyncedsidebarenabled!!!! running traceback (most recent call last):   file "d:\user\dropbox\applications\softwareversioning\sublimetext\sublime_plugin.py", line 538, in run_     return self.run() typeerror: run() missing 1 required positional argument: 'enable' running isnotsyncedsidebarenabled: false 

the problem is, python cannot catch exception throwed run_command( "side_bar_update_sync" ). exception catching errors trying call self.view, when there no self passed by, working fine. full code:

def plugin_loaded():      global isnotsyncedsidebarenabled      packagecontrolsettings = sublime.load_settings('package control.sublime-settings')     usersettings           = sublime.load_settings('preferences.sublime-settings')      def updateissyncedsidebarenabled():          global isnotsyncedsidebarenabled          print('    updateissyncedsidebarenabled!!!!')         sublime.active_window().run_command( "reveal_in_side_bar" )          try:              print( 'running' )             sublime.active_window().run_command( "side_bar_update_sync" )             isnotsyncedsidebarenabled = false             print( 'running this' )          except baseexception:              isnotsyncedsidebarenabled = true             print( 'running also' )          print( 'isnotsyncedsidebarenabled: ' + str( isnotsyncedsidebarenabled ) )        def read_pref_async():          print('read_pref_async!!!!')         updateissyncedsidebarenabled()       def read_pref_package():          print('read_pref_package!!!!')         updateissyncedsidebarenabled()       def read_pref_preferences():          print('read_pref_preferences!!!!')         updateissyncedsidebarenabled()       # read initial setting, after packages being loaded     sublime.set_timeout_async( read_pref_async, 1000 )      # listen changes     packagecontrolsettings.add_on_change( "package control", read_pref_package )     usersettings.add_on_change( "preferences", read_pref_preferences )      #print( usersettings.get( "ignored_packages" ) )     #print( packagecontrolsettings.get( "installed_packages" ) ) 

this discussion may followed sublime text forum's thread: https://forum.sublimetext.com/t/how-to-add-remove-a-default-menu-entry-when-a-x-package-is-isnt-enabled-installed/22753?u=addons_zz

this lines file showed on exception:

532 class applicationcommand(command): 533     def run_(self, edit_token, args): 534         args = self.filter_args(args) 535         if args: 536             return self.run(**args) 537         else: 538             return self.run() 539 540    def run(self): 541        pass1 542 543 ... other classes 

as stated on question, indeed bug on sublime text. here's smaller repro bug report:

import sublime_plugin  class testcommandcommand(sublime_plugin.textcommand):     def run(self, edit):         try:             ret = self.view.window().run_command("toggle_comment", {"fuck": "no"})         except:             print("an exception")         else:             print(ret) 

console:

reloading plugin user.test command: test_command traceback (most recent call last):   file "c:\program files\sublime text 3\sublime_plugin.py", line 792, in run_     return self.run(edit, **args) typeerror: run() got unexpected keyword argument 'fuck' none 

needless say, happens python commands , not internal commands since not error @ all. when try run command sublime.active_window().run_command( "reveal_in_side_bar" ) , not exist, sublime text not throw exception. allow plugins or menu entries not throw errors when not available.
