Plugin should have Processor property

[JohannesRudolph]

I was trying to get this working for testing, but looks like the textstat plugin is no longer compatible with the latest textlint api?

Here's the error I'm getting when I try run one of the only public examples I could find at https://github.com/asciidwango/js-primer/blob/master/tools/textstat.js

Error: Plugin should have Processor property.
module.exports = {
  Processor: class Processor{ ... }
}

What would it take to fix those?

I did a bit of digging on this. Seems it has nothing to do with the textlint's module API but something funky in the way my node wants to load the thing or how an upstream change in textlint-plugin-markdown which I've read has switched to typescript...

Anyhow, I could workaround this by fixing the plugin: require() load for textlint-markdown to unwrap the .default module wrapper.

export async function report(options: ReportOptions) {
    const fileList = await globby(options.globPatterns);
    const textstat = new TextstatKernel();
    const promises = fileList.map((filePath: string) => {
        const text = fs.readFileSync(filePath, "utf-8");
        return textstat.report(text, {
            filePath: filePath,
            ext: path.extname(filePath),
            rules: createTextstatPresetToTextlintPreset(createPreset()),
            plugins: [
                {
                    pluginId: "markdown",
                    plugin: require("@textlint/textlint-plugin-markdown").default
                }
            ],
            sharedDeps: {
                filePathList: fileList,
                locale: options.locale
            }
        });
    });
    return Promise.all(promises);
}

Yes. Probably this is interop issue.
https://www.npmjs.com/package/@textlint/module-interop will cover it.

- plugin: require(https://github.com/textlint/textlint).default
+ plugin: moduleInterop(require("@textlint/textlint-plugin-markdown"))
