# Pkger
|
||||
|
||||
[`github.com/markbates/pkger`](https://godoc.org/github.com/markbates/pkger) is a tool for embedding static files into Go binaries. It will, hopefully, be a replacement for [`github.com/gobuffalo/packr/v2`](https://godoc.org/github.com/gobuffalo/packr/v2).
|
||||
|
||||
## How it Works
|
||||
|
||||
Pkger is powered by the dark magic of Go Modules, so they're like, totally required.
|
||||
|
||||
With Go Modules pkger can resolve packages with accuracy. No more guessing and trying to
|
||||
figure out build paths, GOPATHS, etc... for this tired old lad.
|
||||
|
||||
With the module's path correctly resolved, it can serve as the "root" directory for that
|
||||
module, and all files in that module's directory are available.
|
||||
|
||||
Paths:
|
||||
* Paths should use UNIX style paths:
|
||||
`/cmd/pkger/main.go`
|
||||
* If unspecified the path's package is assumed to be the current module.
|
||||
* Packages can specified in at the beginning of a path with a `:` seperator.
|
||||
github.com/markbates/pkger:/cmd/pkger/main.go
|
||||
* There are no relative paths. All paths are absolute to the modules root.
|
||||
|
||||
```
|
||||
"github.com/gobuffalo/buffalo:/go.mod" => $GOPATH/pkg/mod/github.com/gobuffalo/buffalo@v0.14.7/go.mod
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
Pkger's API is modeled on that of the [`os`](https://godoc.org/os) package in Go's standard library. This makes Pkger usage familiar to Go developers.
|
||||
|
||||
|
||||
|
||||
```go
|
||||
type Pkger interface {
|
||||
Parse(p string) (Path, error)
|
||||
Abs(p string) (string, error)
|
||||
AbsPath(Path) (string, error)
|
||||
Current() (here.Info, error)
|
||||
Info(p string) (here.Info, error)
|
||||
Create(name string) (File, error)
|
||||
MkdirAll(p string, perm os.FileMode) error
|
||||
Open(name string) (File, error)
|
||||
Stat(name string) (os.FileInfo, error)
|
||||
Walk(p string, wf filepath.WalkFunc) error
|
||||
Remove(name string) error
|
||||
RemoveAll(path string) error
|
||||
}
|
||||
|
||||
type File interface {
|
||||
Close() error
|
||||
Abs() (string, error)
|
||||
Info() here.Info
|
||||
Name() string
|
||||
Open(name string) (http.File, error)
|
||||
Path() Path
|
||||
Read(p []byte) (int, error)
|
||||
Readdir(count int) ([]os.FileInfo, error)
|
||||
Seek(offset int64, whence int) (int64, error)
|
||||
Stat() (os.FileInfo, error)
|
||||
Write(b []byte) (int, error)
|
||||
}
|
||||

I was tuning in the shine on the late night dial
|
||||
Doing anything my radio advised
|
||||
With every one of those late night stations
|
||||
Playing songs bringing tears to my eyes
|
||||
I was seriously thinking about hiding the receiver
|
||||
When the switch broke 'cause it's old
|
||||
They're saying things that I can hardly believe
|
||||
They really think we're getting out of control
|
||||
Radio is a sound salvation
|
||||
Radio is cleaning up the nation
|
||||
They say you better listen to the voice of reason
|
||||
But they don't give you any choice 'cause they think that it's treason
|
||||
So you had better do as you are told
|
||||
You better listen to the radio
|
||||
I wanna bite the hand that feeds me
|
||||
I wanna bite that hand so badly
|
||||
I want to make them wish they'd never seen me
|
||||
Some of my friends sit around every evening
|
||||
And they worry about the times ahead
|
||||
But everybody else is overwhelmed by indifference
|
||||
And the promise of an early bed
|
||||
You either shut up or get cut up; they don't wanna hear about it
|
||||
It's only inches on the reel-to-reel
|
||||
And the radio is in the hands of such a lot of fools
|
||||
Tryin' to anesthetize the way that you feel
|
||||
Radio is a sound salvation
|
||||
Radio is cleaning up the nation
|
||||
They say you better listen to the voice of reason
|
||||
But they don't give you any choice 'cause they think that it's treason

So you had better do as you are told

You better listen to the radio
