How to remove things like CodeBlocks from ToPlainText rendering

[kaylumah]

Hi Xoofx,

The repo does not have discussions enabled so I am submitting it here. I apologise in advance if there is a better place to put these kind of questions.

For my blog I am looking into a clean way to count the number of words present in a specific article.

I came across the ToPlainText method for my Markdown. That appears to make it mostly clean text.
However, it leaves in things like the code blocks (my blog is technical, so lots of code snippets).
Is there an extension point I missed, in which I can remove code blocks from the PlainText view?

Any pointers would be appreciated

Thanks for the awesome work you did on both Markdig and Scriban

Not that I'm aware, but you can just take the Markdown AST, search/remove the code blocks, and call PlainText later.

In my own blog post engine, I do it differently, convert to HTML, and extract the text from there with NUglify here

I don't see an equivalent ToText as an extension

markdig/src/Markdig/Markdown.cs

Line 136 in 8e22754

public static void ToHtml(this MarkdownDocument document, TextWriter writer, MarkdownPipeline? pipeline = null)

So based on

markdig/src/Markdig/Markdown.cs

Line 240 in 8e22754

public static MarkdownDocument ToPlainText(string markdown, TextWriter writer, MarkdownPipeline? pipeline = null, MarkdownParserContext? context = null)

I think I need to do something like this

            StringWriter writer = new StringWriter();
            MarkdownDocument document = Markdown.Parse(source, pipeline);
            // todo remove codeblocks from Document.Decendants
            HtmlRenderer renderer = new HtmlRenderer(writer)
            {
                EnableHtmlForBlock = false,
                EnableHtmlForInline = false,
                EnableHtmlEscape = false,
            };
            pipeline.Setup(renderer);

            renderer.Render(document);
            writer.Flush();
            string result = writer.ToString();
            return result;
