## What it is
goldmark is a Markdown parser written in pure Go that is fully compliant with the CommonMark 0.31.2 specification. It features an extensible, interface-based AST that preserves source positions, making it easy to add custom syntax extensions like GitHub Flavored Markdown.

## Use cases
- parse markdown to html in go
- commonmark compliant markdown parser
- render github flavored markdown
- extend markdown with custom syntax
- convert markdown files in a static site generator
- markdown parser with ast access

## When to choose
- you need strict CommonMark compliance in a Go project
- you want to add custom Markdown syntax extensions
- you need an AST that preserves source positions
- you want a pure-Go dependency with no cgo

## When to avoid
- you need maximum raw parsing speed over standards compliance
- you are not working in Go
- you rely on blackfriday-specific non-standard behavior

## Facets
- artifact type: library
- maturity: stable
- function: parser, markdown, templating
- domain: parsers, web-development, documentation
- platform: go, cross-platform, wasm
- tags: commonmark, gfm, ast, extensible, pure-go
