 1 | # **AIMS**witcher
 2 | **AIMS**witcher, **A**n **I**nput **M**ethod **S**witcher that **AIMS** to support switching between Chinese and English input methods or between Chinese and English modes in one input method when switching between Vim's insert and normal modes
 3 | 
 4 | > Note: This tool is only available for Windows
 5 | 
 6 | ## Installation
 7 | Just download the executable file from the [releases page](https://github.com/A-23187/AIMSwitcher/releases/latest)
 8 | 
 9 | ## Usage
10 | ```
11 | AIMSwitcher, An Input Method Switcher
12 | Usage: AIMSwitcher [OPTION]... [ARG]...
13 | 
14 |   --im [INPUTMETHOD]      show the current input method if INPUTMETHOD is omitted,
15 |                           otherwise switch to the specified input method
16 |   --imm [INPUTMETHODMODE] show the current input method mode if INPUTMETHODMODE is omitted,
17 |                           otherwise switch to the specified input method mode
18 | ```
19 | 
20 | ### Examples
21 | AIMSwitcher uses the language identifier (i.e., the locale ID) to switch to the corresponding input method. And the locale ID of Simplified Chinese (zh_CN) is 2052, the locale ID of American English (en_US) is 1033. You can use the option `--im` without argument to discover the locale ID of your current input method
22 | ```sh
23 | # show the locale ID of the current input method
24 | AIMSwitcher.exe --im
25 | ```
26 | 
27 | For me, I installed Microsoft Pinyin input method for Simplified Chinese (2052), and US Keyboard input method for American English (1033). So for switching between these two input methods:
28 | ```sh
29 | # switch to Microsoft Pinyin IM
30 | AIMSwitcher.exe --im 2052
31 | # switch to US Keyboard IM
32 | AIMSwitcher.exe --im 1033
33 | ```
34 | 
35 | Microsoft Pinyin IM supports two language modes: Chinese and English. AIMSwitcher can switch between these two modes like below:
36 | ```sh
37 | # switch to Chinese mode
38 | AIMSwitcher.exe --imm 1025
39 | # switch to English mode
40 | AIMSwitcher.exe --imm 0
41 | 
42 | # you can use this option without argument to find the key of your current mode
43 | AIMSwitcher.exe --imm
44 | ```
45 | > Note: The functionality of switching input method mode has only been tested with Microsoft Pinyin IM, and contributions for testing with other input methods are welcome.
46 | 
47 | ### AIMSwitcher + Vim
48 | - Switch to English input method when leaving insert mode to normal mode
49 | ```vim
50 | autocmd InsertLeave * silent !AIMSwitcher.exe --im 1033
51 | ```
52 | - Switch to English mode of Chinese input method instead of switching input method when leaving insert mode to normal mode
53 | ```vim
54 | autocmd InsertLeave * silent !AIMSwitcher.exe --imm 0
55 | ```
56 | 
57 | ### AIMSwitcher + [VSCodeVim](https://github.com/VSCodeVim/Vim)
58 | - Switch input method
59 | ```json
60 | "vim.autoSwitchInputMethod.enable": true,
61 | // Use English input method by default
62 | "vim.autoSwitchInputMethod.defaultIM": "1033",
63 | "vim.autoSwitchInputMethod.obtainIMCmd": "AIMSwitcher.exe --im",
64 | // Switch to English input method when leaving insert mode to normal mode,
65 | // And the additional argument {im} is just a placeholder, as required by VSCodeVim
66 | "vim.autoSwitchInputMethod.switchIMCmd": "AIMSwitcher.exe --im 1033 {im}"
67 | ```
68 | - Switch input method mode
69 | ```json
70 | "vim.autoSwitchInputMethod.enable": true,
71 | // Use Chinese input method by default (for me, I use Microsoft Pinyin IM)
72 | "vim.autoSwitchInputMethod.defaultIM": "2052",
73 | "vim.autoSwitchInputMethod.obtainIMCmd": "AIMSwitcher.exe --imm",
74 | // Switch to English mode of the Chinese input method when leaving insert mode to normal mode,
75 | // And the additional argument {im} is just a placeholder, as required by VSCodeVim
76 | "vim.autoSwitchInputMethod.switchIMCmd": "AIMSwitcher.exe --imm 0 {im}"
77 | ```
