The reference of the global language models were stored in the class
InputMethodController, however, the global models are global but not a
part of the input method controller, and the input method controller
only use one of the models (McBopomofo/Plain Bopomofo). I guess it
somehow violates SRP and there should be a better place for the global
models.
There was a legacy user override model which creates a folder and a
plist file. If a user uses McBopomofo for years, the folder would
exist. However, when the old override model was removed, I forgot
to create the folder for the new user phrase file.
The bug would let the users with new installation of McBopomofo unable
to add user phrases.
Recent versions of Chrome started to rely on whether composing buffer
gets updated after an arrow key event to determine whether to dismiss
(force commit) the composing buffer and handle the arrow key event for
the omnibox URL suggestions.
When Caps Lock is on and when the character code is not printable, we
should simply reject handling such character instead of absorbing it and
inserting the character to the client buffer--not all apps handle those
insertions.
Using numerous NSLog's led to the discovery that when McBopofomo lost
function (as described in #86), -setValue:forTag:client: was often called
not just on the context of the foreground app, but also on the contexts
of the background apps. This led to the theory that calling keyboard
layout override in that method (not a documented way of doing things
anyways) might corrupt the input method context. That we swapped out
language model and the builder when the method got called didn't help.
In this commit, we put back the keyboard layout override code to where
it belongs -- in -activateServer: -- and we now only swap the language
model and re-create the builder if the input method really changes (e.g.
from Bopomofo to Plain Bopomofo, or vice versa).
Similar defensive coding is also used in the function key handler in the
-handleEvent:client: method.
This is caused by a missing method. Our implementation for
-[NSObject(IMKServerInput) inputText🔑modifiers:client:] was changed
to handleEvent: in 0.9.5.
Interestingly, calling -inputText🔑modifiers:client: somehow worked
when we linked against OS X 10.7 SDK (that was the SDK the 0.9.5
distribution used). This is no longer true with OS X 10.8 SDK.
Also fix two subtle issues:
1. Enter (not Return) key now works in candidate list
2. Cursor index should be compared against builder's length, *not*
composed string's length, because the former is counted in
code point but the latter in UTF-16 units. The composed string's
length might therefore be longer if the string contains
codepoints > U+FFFF, which would cause the cursor mechanism to
be off.
