# go-strip-markdown
|
||||
|
||||
[![GoDoc](https://godoc.org/github.com/writeas/go-strip-markdown?status.svg)](https://godoc.org/github.com/writeas/go-strip-markdown)
|
||||
|
||||
A Markdown stripper written in Go (golang).
|
||||
|
||||
## Usage
|
||||
You could create a simple command-line utility:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"github.com/writeas/go-strip-markdown"
|
||||
"os"
|
||||
)
|
||||
|
||||
func main() {
|
||||
if len(os.Args) < 2 {
|
||||
os.Exit(1)
|
||||
}
|
||||
fmt.Println(stripmd.Strip(os.Args[1]))
|
||||
}
|
||||
```
|
||||
|
||||
You could pass it Markdown and get pure, beauteous text in return:
|
||||
|
||||
```bash
|
||||
./strip "# A Tale of Text Formatting
|
||||
|
||||
_One fateful day_ a developer was presented with [Markdown](https://daringfireball.net/projects/markdown/).
|
||||
And they wanted **none of it**."
|
||||
|
||||
# A Tale of Text Formatting
|
||||
#
|
||||
# One fateful day a developer was presented with Markdown.
|
||||
# And they wanted none of it.
|
||||
```
|
||||
|
||||
## Inspiration
|
||||
This was largely based off of [remove-markdown](https://github.com/stiang/remove-markdown), a Markdown stripper written in Javascript.

||||
