Blackfriday Text

A text renderer for the Blackfriday Markdown Processor.

This can be useful for quick displays of Markdown files, of course, but one use I've found for it is nicer CLI output. For an example, see the output of the ring command from http://github.com/gholt/ring

Example Code

package main

import (
    "io/ioutil"
    "os"

    "github.com/gholt/blackfridaytext"
)

func main() {
    opt := &blackfridaytext.Options{Color: true}
    if len(os.Args) == 2 && os.Args[1] == "--no-color" {
        opt.Color = false
    }
    markdown, _ := ioutil.ReadAll(os.Stdin)
    metadata, output := blackfridaytext.MarkdownToText(markdown, opt)
    for _, item := range metadata {
        name, value := item[0], item[1]
        os.Stdout.WriteString(name)
        os.Stdout.WriteString(":\n    ")
        os.Stdout.WriteString(value)
        os.Stdout.WriteString("\n")
    }
    os.Stdout.WriteString("\n")
    os.Stdout.Write(output)
    os.Stdout.WriteString("\n")
}

Sample Input

To give an idea of what the output looks like, I've run this document through the renderer and appended the output.

Here is a sample list.
Two
- And a sublist.
- Two, part B.
Three

Emphasis, Double Emphasis, Triple Emphasis, ~~Strikethrough~~, and code spans along with http://auto/linking and explicit linking.

Here's a quick table from the blackfriday example:

Name	Age
Bob	27
Alice	23

No-Color Output
