It is a string divided into three lines.

1. The first line is a serialized JSON string representing the coordinates and characters of the current environment's intersection points (there may be multiple characters, hence it is a list).
2. The second line is also a serialized JSON string representing all character information in the current environment (there may be multiple characters at each coordinate point, hence it is also a list), with the characters at the front of the array being at the topmost layer, descending accordingly.
3. The third line is a numeric string, either 0 or 1, indicating whether to use normal mode or super mode (super mode offers more intersection possibilities but requires a specific font).

• output data

{"10,75":"┿","10,78":"┿"}

A serialized JSON string representing the intersection characters that need to be filled for certain specific coordinates.

Example of calling this library in a Vim script:

vimio/autoload/vimio/utils.vim:
    let s:vimio_cached_lib_path = ''
    function! vimio#utils#get_vimio_libs_path() abort
        if empty(s:vimio_cached_lib_path)
            let plugin_root = vimio#utils#get_plugin_root()
            if has('win32') || has('win64')
                let s:vimio_cached_lib_path = plugin_root . '/libs/libvimio.dll'
            elseif has('mac')
                let s:vimio_cached_lib_path = plugin_root . '/libs/libvimio.dylib'
            else
                let s:vimio_cached_lib_path = plugin_root . '/libs/libvimio.so'
            endif
        endif

        return s:vimio_cached_lib_path
    endfunction

vimio/autoload/vimio/scene.vim:
    function! vimio#scene#get_cross_chars_native(cross_point, all_chars) abort
        let cross_json = json_encode(a:cross_point)
        let all_json = json_encode(a:all_chars)
        let mode = (g:vimio_vimiomono_super_slash_mode.index ==# 0)? '0' : '1'
        let input = cross_json . "\n" . all_json . "\n" . mode

        let result_json = libcall(vimio#utils#get_vimio_libs_path(), 'vimio_get_cross_chars', input)
        return json_decode(result_json)
    endfunction

    function! vimio#scene#get_cross_chars(cross_point, all_chars) abort
        let result = vimio#scene#get_cross_chars_native(a:cross_point, a:all_chars)

        for [key, center_char] in items(result)
            if has_key(g:vimio_config_draw_cross_styles[g:vimio_state_cross_style_index], center_char)
                let result[key] = g:vimio_config_draw_cross_styles[g:vimio_state_cross_style_index][center_char]
            endif
        endfor
        return result
    endfunction

Notice!

After compiling the dll, please do not use the cp command in the cygwin environment to copy it to the target path, as this may cause confusion in the dll file permissions and make it impossible to execute.
