稍微修改resourceRegExp时，NormalModuleReplacementPlugin不起作用

标签： webpack ckeditor icons theming

如CKEditor5 homepage上的正式建议，我想替换几个插件预装的标准图标。 由于每个插件（例如ckeditor5-core或ckeditor5-alignment）都在[PLUGIN_DIR] / theme / icons中提供了自己的.svg设置，因此建议的策略-用自己修改的替换它们-是可以理解和明确的：

  

（...）使用webpack的NormalModuleReplacementPlugin插件

...
plugins: [
  new webpack.NormalModuleReplacementPlugin(
    /bold\.svg/,
    '/absolute/path/to/my/icon.svg'
  )
]

基于此代码，我进行了实验并得出以下结论：

...
plugins: [
  new webpack.NormalModuleReplacementPlugin(
    /\/theme\/icons\/[^/]+\.svg$/,
    resource => {
      console.log(resource.request);
      resource.request = path.resolve(
        THEME_PATH,
        "../../icons/coffee-solid.svg"
      );
    }
  ),
]

这会导致以下（期望/预期）更改： before after

部分控制台输出：

../../theme/icons/bold.svg
../../theme/icons/italic.svg
@ckeditor/ckeditor5-core/theme/icons/quote.svg
@ckeditor/ckeditor5-core/theme/icons/image.svg
../theme/icons/numberedlist.svg
../theme/icons/bulletedlist.svg
../theme/icons/align-justify.svg
../theme/icons/link.svg

@ckeditor/ckeditor5-core/theme/icons/check.svg
@ckeditor/ckeditor5-core/theme/icons/check.svg

../../theme/icons/unlink.svg
../../theme/icons/image_placeholder.svg
../theme/icons/align-center.svg
../theme/icons/align-right.svg
../theme/icons/align-left.svg

但是，当我想通过各自的正则表达式将文件夹限制为@ckeditor时，会发生以下情况：

...
plugins: [
  new webpack.NormalModuleReplacementPlugin(
    /ckeditor5-[^/]+\/theme\/icons\/[^/]+\.svg$/,
    resource => {
      console.log(resource.request);
      resource.request = path.resolve(
        THEME_PATH,
        "../../icons/coffee-solid.svg"
      );
    }
  ),
]

之前（见上文）

after

为什么会发生？

注意：我必须对资源使用语法（据我所知，这是另一种选择），因为我想稍后动态加载图标。

答案 0 :(得分：0)

正如我在https://github.com/ckeditor/ckeditor5/issues/1831中回答的那样：

正如您在NormalModuleReplacementPlugin的源代码上所看到的那样，对正则表达式进行了两次测试，一次在请求解析之前，一次在资源解析之后。

大多数情况下，您可能会看到在解析之后调用函数（因为请求与正则表达式不匹配）。加载程序会增强解析后的请求（这就是路径如此之长且包含奇怪字符的原因），实际上，此选项已不再使用。因此，您应该更改result.resource而不是result.request。

例如尝试以下插件：

new webpack.NormalModuleReplacementPlugin(
    /ckeditor5-[^/]+\/theme\/icons\/bold\.svg/,
    result => {
        if ( result.resource ) {
            result.resource = result.resource.replace( 'bold', 'code' );
        }
    }
)

以下摘要可能对每个想要的人都有用 完全控制CKEditor5的外观。

/*
THEME_PATH := path to your theme folder (that contains /theme/theme.css)
-> see https://github.com/ckeditor/ckeditor5-theme-lark (use it as a template)
Both REPLACE_ICONS_REGEXP and replaceIcons should be use as described above
*/

const REPLACE_ICONS_REGEXP = /ckeditor5-[^/]+\/theme\/icons\/[^/]+\.svg$/;

function replaceIcons(resource) {
  {
    const [, ckeditorPlugin, svgFileToReplace] = resource.request.match(
      /(ckeditor5-[^/]+)\/theme\/icons\/([^/]+\.svg)$/
    );

    const designatedSvgPath = path.resolve(
      THEME_PATH,
      `../../icons/${svgFileToReplace}`
    );

    try {
      fs.accessSync(designatedSvgPath, fs.constants.F_OK);
      resource.resource = designatedSvgPath; // as ma2ciek suggested
    } catch (err) {
      try {
        // Create mock file to be replaced with themed svg
        fs.writeFileSync(
          path.resolve(THEME_PATH, `../../icons/_${svgFileToReplace}`),
          ""
        );
      } catch (err) {
        err.message =
          `Unable to create icon mock file for ${ckeditorPlugin}.\n` +
          err.message;
        throw err;
      }
    }
  }
}
