关于fonts.vbs的建议

[similing4]

建议直接在运行时判断文件是否存在，如果不存在则通过fs库将vbs内容写出到这个位置就好了

[similing4]

我写了个例子：

const getFontScript = `Option Explicit

Dim objShell, objFSO, objFile, objFolder
Dim objFolderItem, colItems, objFont
Dim strFileName


Const FONTS = &H14& ' Fonts Folder

' Instantiate Objects
Set objShell = CreateObject("Shell.Application")
Set objFolder = objShell.Namespace(FONTS)
Set objFolderItem = objFolder.Self
Set colItems = objFolder.Items
Set objFSO = CreateObject("Scripting.FileSystemObject")

For Each objFont in colItems
    WScript.StdOut.WriteLine(objFont.Path & vbtab & objFont.Name)
Next

Set objShell = nothing
Set objFile = nothing
Set objFolder = nothing
Set objFolderItem = nothing
Set colItems = nothing
Set objFont = nothing
Set objFSO = nothing

wscript.quit`;
const fs = require('fs');
const path = require('path');
const execFile = require('child_process').execFile;
const iconv = require('iconv-lite');
const getFontsFromText = function(str) {
	let arr = str.split("\n");
	arr = arr.filter((r, ind) => {
		return ind > 2 && r.split("\t").length > 1;
	}).map((r) => {
		let res = r.trim()
			.split("\t");
		res[0] = res[0].split("\\")[res[0].split("\\").length - 1];
		res[1] = res[1].replace(/^\s+|\s+$/g, '')
			.replace(/(Regular|常规)$/i, '')
			.replace(/^\s+|\s+$/g, '');
		return {
			fontNickname: res[0],
			fontName: res[1]
		};
	});
	return arr;
};
module.exports = function() {
	return new Promise((recv, recj) => {
		const fontsVbsFile = path.resolve('./').replace(/\\/g, '/') + "/fonts.vbs";
		if (!fs.existsSync(fontsVbsFile))
			fs.writeSync(fontsVbsFile, getFontScript);
		execFile('cscript', [fontsVbsFile], {
			maxBuffer: 1024 * 1024 * 10,
			encoding: 'binary'
		}, (err, stdout, stderr) => {
			let fonts = []
			if (err) {
				recj(err)
				return
			}
			stdout = iconv.decode(Buffer.from(stdout, 'binary'), 'cp936');
			fonts = getFontsFromText(stdout);
			console.log(fonts);
			recv(fonts)
		});
	});
}

感谢建议。不过不是很明白，为什么需要这样处理呢？ 目前已知 Electron 环境并且打包为 asar 的情况下，是无法直接执行这个 vbs 的，因此目前的代码中这种情况下会先将 vbs 写到临时目录再执行，还有其他场景需要这样操作吗？
