Plug 'Neur1n/neuims'

If one does not want to always enable this plugin, using the on-demand loading feature of vim-plug is recommended. Details of the command :IMSToggle will be discussed in the following.

Plug 'Neur1n/neuims', {'on': 'IMSToggle'}

This plugin needs to be manually enabled before being used to switch input methods. There are two ways to enable:

1. Using the command :IMSToggle.
2. Calling the function neuims#Toggle(), or using a key mapping, e.g.:

nnoremap <silent> <leader>it :call neuims#Toggle()<CR>

The command :IMSToggle is provided specifically for the purpose of working with the on-demand loading feature of vim-plug. While using on-demand loading to load this plugin, any functions of which will not be called before the :IMSToggle command is called to enable neuims for the first time. This should benefits those who work with multiple input methods occasionally.

While in enabled status, use :IMSToggle or <leader>it again.

Usually, the switching is automatically controlled by the InsertEnter and InsertLeave event. However, one may call the function neuims#Switch(0) to switch manually, or using a key mapping, e.g.:

nnoremap <silent> <leader>is :call neuims#Switch()<CR>

There are default configurations in the soure code:

let s:win = {
      \ 'im': 'US Keyboard',
      \ 'status': 0,
      \ 'keyboards': {
      \   'US Keyboard': 0x0409,
      \   'Microsoft Pinyin': 0x0804,
      \ },
      \ }

let s:ibus = {
      \ 'im': 'English (US)',
      \ 'status': 0,
      \ 'keyboards': {
      \   'English (US)': 'xkb:us::eng',
      \   'Pinyin': 'pinyin',
      \ },
      \ }

This should work well with Windows's (7/10) and Ubuntu's (16.04) built-in input methods. Let's break it down:

• im: The input method specified here should be the "default" one, which is the one in normal mode.
• status: 0 means neuims is not enabled, 1 means neuims is enabled. It is controlled by the plugin itself, the user shall not care about it.
• keyboards: The two input methods one wants to use in normal/insert mode should be specified here, one of which must have the same name of that in im. For example, if im is specified as "English (US)", then there has to be "English (US)" in keyboards.

For example, if one uses RIME (IBus based) in Ubuntu, the configuration may be:

let g:neuims = {
      \ 'im': 'English (US)',
      \ 'status': 0,
      \ 'keyboards': {
      \   'English (US)': 'xkb:us::eng',
      \   'Rime': 'rime',
      \ },
      \ }

Basically, these are questions I asked myself.

A: I have not found a proper solution for input method switching for Windows up to 2020.01.09.

A: I wish I could use some CMD or PowerShell commands to finish the job, but I have not found something working so far.

A: You should really update neuims right now. The dependencies were removed!🎉

A: Support for Ubuntu may be done soon, but I do not have a MacBook.

A: Support for IBus is released on 2020.01.16, tested on Ubuntu 16.04. I still do not have a MacBook.

[x] Support Windows 7/10

[x] Support Linux (IBus)

[x] Provide a status notification for statusline. (Please check commit ff8c961 of my configuration.)

[ ] Identify MinGW, WSL, etc.

[ ] Use Windows TSF for refactoring, or use librime to achieve (limited to Rime but) unity and cross platform solution.

• Thanks to @elxy, Python dependencies were removed since fe2abf1.
