## Legacy API type versions
This package includes types for legacy API versions. The stable version of the API types live in `api/types/*.go`.
Consider moving a type here when you need to keep backwards compatibility in the API. This legacy types are organized by the latest API version they appear in. For instance, types in the `v1p19` package are valid for API versions below or equal `1.19`. Types in the `v1p20` package are valid for the API version `1.20`, since the versions below that will use the legacy types in `v1p19`.
### Package name conventions
The package name convention is to use `v` as a prefix for the version number and `p`(patch) as a separator. We use this nomenclature due to a few restrictions in the Go package name convention:
1. We cannot use `.` because it's interpreted by the language, think of `v1.20.CallFunction`.
2. We cannot use `_` because golint complains about it. The code is actually valid, but it looks probably more weird: `v1_20.CallFunction`.
For instance, if you want to modify a type that was available in the version `1.21` of the API but it will have different fields in the version `1.22`, you want to create a new package under `api/types/versions/v1p21`.

# go-shellwords
[![Coverage Status](https://coveralls.io/repos/mattn/go-shellwords/badge.png?branch=master)](https://coveralls.io/r/mattn/go-shellwords?branch=master)
[![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"]
```
