input source の確認
from AppKit import NSTextInputContext , NSTextView
txt = NSTextInputContext.alloc().initWithClient_( NSTextView.new() )
print( txt.selectedKeyboardInputSource() )
# => com.apple.keylayout.US
input source の切替
from AppKit import NSTextInputContext , NSTextView
txt = NSTextInputContext.alloc().initWithClient_( NSTextView.new() )
txt.setValue_forKey_('com.apple.inputmethod.Kotoeri.Japanese', 'selectedKeyboardInputSource')
# => Kotoeri に切り替わる
input source 切替の通知
import Foundation
from AppKit import NSObject, NSTextInputContext , NSTextView, NSTextInputContextKeyboardSelectionDidChangeNotification
from PyObjCTools import AppHelper
import objc
class Observer(NSObject):
# initialize method
def initWithValue_(self, txtObj):
self = objc.super(Observer, self).init()
self.text_input_context = txtObj
return self
# add handler
def bundle_(self, aNotification):
print( self.text_input_context.selectedKeyboardInputSource() )
# create Cocoa's text obj
txtObj = NSTextInputContext.alloc().initWithClient_( NSTextView.new() )
# createt observer obj
obs = Observer.new().initWithValue_( txtObj )
# create notify obj
notify_obj = Foundation.NSNotificationCenter.defaultCenter()
# add event to notify obj
notify_obj.addObserver_selector_name_object_(
obs
, 'bundle:'
, NSTextInputContextKeyboardSelectionDidChangeNotification
, None
)
# do console-loop
AppHelper.runConsoleEventLoop()
# --- Kotoeri に切り替える ---
# => com.apple.inputmethod.Kotoeri.Japanese
# --- US に切り替える ---
# => com.apple.keylayout.US
課題
通知を使わずに現在の input source を知る方法がわからない
下記のコードは最初の input source しかわからない
from AppKit import NSTextInputContext , NSTextView
def loop():
txt = NSTextInputContext.alloc().initWithClient_( NSTextView.new() )
while True:
if input() == '':
break
else:
print( txt.selectedKeyboardInputSource() )
loop()
# a
# => com.apple.keylayout.US
# あ
# => com.apple.keylayout.US
# a
# => com.apple.keylayout.US
# あ
# => com.apple.keylayout.US
teratailで質問なげたった
(macOSX) selectedKeyboardInputSource がうまくはたらないです
Carbon's way
input source の確認
from Foundation import NSBundle
import objc
# use HITToolbox's functions
HIToolbox_bundle = NSBundle.bundleWithIdentifier_("com.apple.HIToolbox")
# bundle many...
HIToolbox_functions = [ ('TISGetInputSourceProperty', b'@@@'), ('TISCopyCurrentKeyboardInputSource', b'@') ]
HIToolbox_constants = [ ('kTISPropertyInputModeID', b'@') ]
objc.loadBundleFunctions(HIToolbox_bundle, globals(), HIToolbox_functions)
objc.loadBundleVariables(HIToolbox_bundle, globals(), HIToolbox_constants)
print( TISGetInputSourceProperty(TISCopyCurrentKeyboardInputSource() , kTISPropertyInputModeID ) )
input source の切替
import CoreFoundation
import ctypes
import ctypes.util
# add carbon lib
carbon = ctypes.cdll.LoadLibrary(ctypes.util.find_library('Carbon'))
# re-define arg and return types
carbon.TISSelectInputSource.restype = ctypes.c_void_p
carbon.TISSelectInputSource.argtypes = [ctypes.c_void_p]
carbon.TISCopyInputSourceForLanguage.argtypes = [ctypes.c_void_p]
carbon.TISCopyInputSourceForLanguage.restype = ctypes.c_void_p
lang = 'en'
carbon.TISSelectInputSource(
carbon.TISCopyInputSourceForLanguage(
CoreFoundation.CFSTR(lang).__c_void_p__())
)

How can we reading / coerce CFArray and CFString etc values from within OS X JXA?
