implement by send romaji sequence or kana keycode

how to handle layer state in modal app, like vim, 's insert mode?

to use unused led or qmk/qmk_firmware#921.
in the future, may use qmk/qmk_firmware#895
kana lock led is ideal. but it doesn't work with us layout. maybe modifying xkb setting is needed.
use num lock for now.

other functions that conflict with english layout

confirm with punctuation
use one side of space for other function of ime
enter once to break line

misc

make CLEAR also ensure that layer state matches ime state by sending keycode that make ime off and set layer default.
if modifier is pressed send keycode of default layer.

Should handle BS or Del erase whether last character or other character is left.

• if last character then im_state will be PreComposition
• if other character is left then im_state will be Predict or Composition

To handle properly, should consider cursor position and count of character.
And how can I handle long press ?

For now, give up as-you-type conversion for functional keys after BS/Del.
Set im_state to PreComposiotion after BS/Del in any conditions.

Problems

Windows doesn't let me change keyboard layout

• without reboot
• and per user
• and per keyboard without modifying the registory

Changing keyboard layout affects other user.
I prefer us layout for symbols but most people in Japan use jp layout.

On Windows, kana , henkan or muhenkan key don't respond with us layout.

Possible solution

use jp keycode
remap shift side keycode in process record

modify the registry so that my keyboard is recognized as us layout.
map IME on/off etc to some unused keycode

or use layer tap beyond 16 layer somehow.

To produce けげ, now it has to be typed
press カ＋エ、leave カ＋エ、pressエ＋カ、leave エ＋カ.
This is easier to type.
press カ＋エ、leave カ、press カ、leave カ＋エ

Incidentally,
press イ＋サ（イ first）、leave イ、press ア、produce じざ.

It's most likely that I recognize making mistake about kana chord shift.

Use pinky columns with index and middle by moving home position

When type with pinky, should keep ring raised. That hurts ring.
Excessive use thumb to change layer hurts thumb.
Changing layer with index or middle conflict other modifier.

• Place number and cursor keys on pinky columns
• Place frequently used functions and symbols on number row

Put, symbols shifted or not on default layer, together in the layer for symbol

Mix use of shift and symbol layer cause confusion.

may be able to use full width space to fix it.

how to reproduce

enter insert mode
turn on ime
leave insert mode
press ime toggle key

result

kana layer
ime off

expected

kana layer
ime on

how to reproduce

turn on ime
leave insert mode
enter insert mode with modifier key such as A or I

determine when release only

determine as soon as it can be determined

key

register after SIMULTANEOUS_TERM
register when next key is pressed
register when next mod is pressed and that is not simultaneous

mod

register after TAPPING_TERM
tap when the mod is released within TAPPING_TERM
register when simultaneous tapping

unregister before register prev key that is pressed just before the mod is released

• 2 rollover with kana chord
• n rollover with kana chord

I prefer shift delay rather than permissive hold.

• replace XXXX_T(key)

to write kana list or table, preedit text is so annoying.

qmk/qmk_firmware#2471

isn't updated properly

conflict with caps lock

How to cooperate led_set_user and default_layer_set_user ?

related #17

alphabet, symbol etc

Currently I have to care about shifting order.
In order to get rid of it, I can use simultaneous shft instead.
But current keymap don't have enough key combination.
Maybe it's better even this cause more key pressing.

Implementation

Use 3 keys for 濁音 or 外来音
Use 4 keys for 濁音 and 外来音
Press consonant/vowel key with middle finger and neighbor key with index finger. (middle + index or index + inner)

I use Numlock currently.
This can cause problem if another keyboard is used together.

If I can select candidate by numeric keys, predictive conversion seems to be useful.

Possible implementation is this

no input

input number

preedit

1. change state to predictive conversion
2. select candidate by number

conversion

select candidate by number

To implement it, input state should be handled by the keyboard.

starting state: no input
some character: preedit
convert or predict: conversion
commit: no input
ime off: no input

If left hand consonant and right hand vowel are pressed simultaneously, send consonant then vowel.
Send frequently used bigrams if neighbor keys on index and middle finger are pressed simultaneously.
Bigrams that cannot be covered by consonant and vowel pair have priority.

For example
t+a=ta
e+a=ea
s+t+o=sto
t+i+o=tio

bi-consonants

th
st
ch
rn

bi-vowels

ou
