|
|
|
goldmark-meta is an extension for the [goldmark](http://github.com/yuin/goldmark)
|
|
that allows you to define document metadata in YAML format.
|
|
|
|
Usage
|
|
--------------------
|
|
|
|
### Installation
|
|
|
|
```
|
|
go get github.com/yuin/goldmark-meta
|
|
```
|
|
|
|
### Markdown syntax
|
|
|
|
YAML metadata block is a leaf block that can not have any markdown element
|
|
as a child.
|
|
|
|
YAML metadata must start with a **YAML metadata separator**.
|
|
This separator must be at first line of the document.
|
|
|
|
A **YAML metadata separator** is a line that only `-` is repeated.
|
|
|
|
YAML metadata must end with a **YAML metadata separator**.
|
|
|
|
You can define objects as a 1st level item. At deeper level, you can define
|
|
any kind of YAML element.
|
|
|
|
Example:
|
|
|
|
```
|
|
---
|
|
Title: goldmark-meta
|
|
Summary: Add YAML metadata to the document
|
|
Tags:
|
|
- markdown
|
|
- goldmark
|
|
---
|
|
|
|
# Heading 1
|
|
```
|
|
|
|
|
|
### Access the metadata
|
|
|
|
```go
|
|
import (
|
|
"bytes"
|
|
"fmt"
|
|
"github.com/yuin/goldmark"
|
|
"github.com/yuin/goldmark/extension"
|
|
"github.com/yuin/goldmark/parser"
|
|
"github.com/yuin/goldmark-meta"
|
|
)
|
|
|
|
func main() {
|
|
markdown := goldmark.New(
|
|
goldmark.WithExtensions(
|
|
meta.Meta,
|
|
),
|
|
)
|
|
source := `---
|
|
Title: goldmark-meta
|
|
Summary: Add YAML metadata to the document
|
|
Tags:
|
|
- markdown
|
|
- goldmark
|
|
---
|
|
|
|
# Hello goldmark-meta
|
|
`
|
|
|
|
var buf bytes.Buffer
|
|
context := parser.NewContext()
|
|
if err := markdown.Convert([]byte(source), &buf, parser.WithContext(context)); err != nil {
|
|
panic(err)
|
|
}
|
|
metaData := meta.Get(context)
|
|
title := metaData["Title"]
|
|
fmt.Print(title)
|
|
}
|
|
```
|
|
|
|
### Render the metadata as a table
|
|
|
|
You need to add `extension.TableHTMLRenderer` or the `Table` extension to
|
|
render metadata as a table.
|
|
|
|
```go
|
|
import (
|
|
"bytes"
|
|
"fmt"
|
|
"github.com/yuin/goldmark"
|
|
"github.com/yuin/goldmark/extension"
|
|
"github.com/yuin/goldmark/parser"
|
|
"github.com/yuin/goldmark/renderer"
|
|
"github.com/yuin/goldmark/util"
|
|
"github.com/yuin/goldmark-meta"
|
|
)
|
|
|
|
func main() {
|
|
markdown := goldmark.New(
|
|
goldmark.WithExtensions(
|
|
meta.New(meta.WithTable()),
|
|
),
|
|
goldmark.WithRendererOptions(
|
|
renderer.WithNodeRenderers(
|
|
util.Prioritized(extension.NewTableHTMLRenderer(), 500),
|
|
),
|
|
),
|
|
)
|
|
// OR
|
|
// markdown := goldmark.New(
|
|
// goldmark.WithExtensions(
|
|
// meta.New(meta.WithTable()),
|
|
// extension.Table,
|
|
// ),
|
|
// )
|
|
source := `---
|
|
Title: goldmark-meta

|
|
if err := markdown.Convert([]byte(source), &buf); err != nil {
|
|
panic(err)
|
|
}
|
|
fmt.Print(buf.String())
|
|
}
