# go-shellwords
[![codecov](https://codecov.io/gh/mattn/go-shellwords/branch/master/graph/badge.svg)](https://codecov.io/gh/mattn/go-shellwords)
[![Build Status](https://travis-ci.org/mattn/go-shellwords.svg?branch=master)](https://travis-ci.org/mattn/go-shellwords)
Parse line as shell words.
## Usage
```go
args, err := shellwords.Parse("./foo --bar=baz")
// args should be ["./foo", "--bar=baz"]
```
```go
os.Setenv("FOO", "bar")
p := shellwords.NewParser()
p.ParseEnv = true
args, err := p.Parse("./foo $FOO")
// args should be ["./foo", "bar"]
```
```go
p := shellwords.NewParser()
p.ParseBacktick = true
args, err := p.Parse("./foo `echo $SHELL`")
// args should be ["./foo", "/bin/bash"]
```
```go
shellwords.ParseBacktick = true
p := shellwords.NewParser()
args, err := p.Parse("./foo `echo $SHELL`")
// args should be ["./foo", "/bin/bash"]
```
