add options glyphTransformFn

[chenyulun]

I have a project font and css is split, I need to rewrite the packaging according to the original unicode table to package, I hope to provide a glyphTransformFn configuration, pass me the file name or other information, I return the unicode

glphMap.json

{
"toast-loading": 59538,
  "no-voice": 59539,
  "have-noice": 59540,
  "warning": 59541
}

svgtofont.js

svgtofont({
  src: path.resolve(process.cwd(), "src/svg-icons"), // svg path
  dist: path.resolve(process.cwd(), "font"), // output path
  // styleTemplates: path.resolve(rootPath, "styles"), // file templates path (optional)
  fontName: "iconfont", // font name
  classNamePrefix: 'poppy-icon',
  css: true, // Create CSS files.
  startUnicode: 0xea01, // unicode start number
  getIconUnicode(name, startUnicode) {
let unicode,nextUniCode = startUnicode
     if (glphMap[name]) {
        unicode = String.fromCharCode(glphMap[name]);
      } else {
        unicode = String.fromCharCode(startUnicode++)
        nextUniCode = startUnicode
      }
      return [unicode,nextUniCode]
  },
  svgicons2svgfont: {
    fontHeight: 1000,
    normalize: true
  }
}).then(() => {
  console.log('done!');
});;

add patch-package The following code is available

const glphMap = fs.readJSONSync("./glphMap.json");

  fontName: "iconfont", // font name
  classNamePrefix: "poppy-icon",
  css: true, // Create CSS files.
  startUnicode: 0xe896, // unicode start number,   latast  glphMap.json  "warning": 59541,  59541+1 === 0xe896
  getIconUnicode(name, startUnicode) {
    let unicode,
      nextUniCode = startUnicode;
    if (glphMap[name]) {
      unicode = String.fromCharCode(glphMap[name]);
    } else {
      unicode = String.fromCharCode(startUnicode);
      nextUniCode = startUnicode + 1;
      glphMap[name] = startUnicode
    }
    return [unicode, nextUniCode];
  },

@chenyulun

getIconUnicode(name) {

@chenyulun

getIconUnicode(name, unicode) {

  return glphMap[name];

@chenyulun Is the api designed this way simpler?

[chenyulun]

有一部分是新增的图标，自然递增就行了，api能确保里面的计算的和配置传入的没冲突就行，Utils里面的函数又设置Unicodeobject，又做了对象值的返回，
也可以把这个配置函数往下传，在内部的getIconUnicode里面先获取配置的Unicode，没有的情况再递增算，这样最简单

[chenyulun]

就是判断useNameAsUnicode是否存在之前，先执行配置function，如果能获取用户传入的Unicode，就用用户配置的，没有在进行下面的文件名或者自增计算Unicode的逻辑

@chenyulun Upgrade v3.25.1

svgtofont/src/index.ts

Lines 102 to 103 in e20b129

	/** Get Icon Unicode */
	getIconUnicode?: (name: string, unicode: string, startUnicode: number) => [string, number];

[jaywcjlove]

getIconUnicode(name, unicode, startUnicode) {
  glphMap[name] = glphMap[name] || unicode;
  return [glphMap[name], startUnicode];
}

nice
