Modifying the AST and Rewriting the AST to Markdown

[matttproud]

Hi,

goldmark looks like a nice suite of functionality. I have been examining it, and I am wondering if there is any capability analogous to package dst's (a replacement for Go's own package ast) ability to dump out modified ASTs with all elements intact (example).

Let's say that I wrote my own parser.ASTTransformer or ast.Walker that I used to modify the Markdown document. Does goldmark provide a way for me to re-emit the modified AST back to Markdown source (but reflecting the modifications to the AST that I made in the walker or transformer)?

Many thanks in advance!

Would a text renderer work here? Though I think some information is lost during parsing (such as extra blank lines), so it wouldn't be exact.

Personally, I'd like something lik go fmt for markdown to run on pre-commit hooks, rendering all lists with my preferred marker, keeping lines truncated to 80, etc.
