# packr
[![GoDoc](https://godoc.org/github.com/gobuffalo/packr?status.svg)](https://godoc.org/github.com/gobuffalo/packr)
Packr is a simple solution for bundling static assets inside of Go binaries. Most importantly it does it in a way that is friendly to developers while they are developing.
## Intro Video
To get an idea of the what and why of packr, please enjoy this short video: [https://vimeo.com/219863271](https://vimeo.com/219863271).
## Installation
```text
$ go get -u github.com/gobuffalo/packr/...
```
## Usage
### In Code
The first step in using Packr is to create a new box. A box represents a folder on disk. Once you have a box you can get `string` or `[]byte` representations of the file.
```go
// set up a new box by giving it a (relative) path to a folder on disk:
box := packr.NewBox("./templates")
// Get the string representation of a file:
html := box.String("index.html")
// Get the string representation of a file, or an error if it doesn't exist:
html, err := box.MustString("index.html")
// Get the []byte representation of a file:
html := box.Bytes("index.html")
// Get the []byte representation of a file, or an error if it doesn't exist:
html, err := box.MustBytes("index.html")
```
### What is a Box?
A box represents a folder, and any sub-folders, on disk that you want to have access to in your binary. When compiling a binary using the `packr` CLI the contents of the folder will be converted into Go files that can be compiled inside of a "standard" go binary. Inside of the compiled binary the files will be read from memory. When working locally the files will be read directly off of disk. This is a seamless switch that doesn't require any special attention on your part.
#### Example
Assume the follow directory structure:
```
├── main.go
└── templates
├── admin
│   └── index.html
└── index.html
```
The following program will read the `./templates/admin/index.html` file and print it out.
```go
package main
import (
"fmt"
"github.com/gobuffalo/packr"
)
func main() {
box := packr.NewBox("./templates")
s := box.String("admin/index.html")
fmt.Println(s)
}
```
### Development Made Easy
In order to get static files into a Go binary, those files must first be converted to Go code. To do that, Packr, ships with a few tools to help build binaries. See below.
During development, however, it is painful to have to keep running a tool to compile those files.
Packr uses the following resolution rules when looking for a file:
1. Look for the file in-memory (inside a Go binary)
1. Look for the file on disk (during development)
Because Packr knows how to fall through to the file system, developers don't need to worry about constantly compiling their static files into a binary. They can work unimpeded.
Packr takes file resolution a step further. When declaring a new box you use a relative path, `./templates`. When Packr recieves this call it calculates out the absolute path to that directory. By doing this it means you can be guaranteed that Packr can find your files correctly, even if you're not running in the directory that the box was created in. This helps with the problem of testing, where Go changes the `pwd` for each package, making relative paths difficult to work with. This is not a problem when using Packr.
---
## Usage with HTTP
A box implements the [`http.FileSystem`](https://golang.org/pkg/net/http/#FileSystemhttps://golang.org/pkg/net/http/#FileSystem) interface, meaning it can be used to serve static files.
```go
package main
import (
"net/http"
"github.com/gobuffalo/packr"
)
func main() {
box := packr.NewBox("./templates")
http.Handle("/", http.FileServer(box))
http.ListenAndServe(":3000", nil)
}
```
---
## Building a Binary (the easy way)
When it comes time to build, or install, your Go binary, simply use `packr build` or `packr install` just as you would `go build` or `go install`. All flags for the `go` tool are supported and everything works the way you expect, the only difference is your static assets are now bundled in the generated binary. If you want more control over how this happens, looking at the following section on building binaries (the hard way).
## Building a Binary (the hard way)
Before you build your Go binary, run the `packr` command first. It will look for all the boxes in your code and then generate `.go` files that pack the static files into bytes that can be bundled into the Go binary.
```
$ packr
```
Then run your `go build command` like normal.
*NOTE*: It is not recommended to check-in these generated `-packr.go` files. They can be large, and can easily become out of date if not careful. It is recommended that you always run `packr clean` after running the `packr` tool.
#### Cleaning Up
When you're done it is recommended that you run the `packr clean` command. This will remove all of the generated files that Packr created for you.
```
$ packr clean
```
Why do you want to do this? Packr first looks to the information stored in these generated files, if the information isn't there it looks to disk. This makes it easy to work with in development.
---
## Debugging
The `packr` command passes all arguments down to the underlying `go` command, this includes the `-v` flag to print out `go build` information. Packr looks for the `-v` flag, and will turn on its own verbose logging. This is very useful for trying to understand what the `packr` command is doing when it is run.

Package errors provides simple error handling primitives.
`go get github.com/pkg/errors`
The traditional error handling idiom in Go is roughly akin to
```go
if err != nil {
return err
}
```
which applied recursively up the call stack results in error reports without context or debugging information. The errors package allows programmers to add context to the failure path in their code in a way that does not destroy the original value of the error.
## Adding context to an error
The errors.Wrap function returns a new error that adds context to the original error. For example
```go
_, err := ioutil.ReadAll(r)
if err != nil {
return errors.Wrap(err, "read failed")
}
```
## Retrieving the cause of an error
Using `errors.Wrap` constructs a stack of errors, adding context to the preceding error. Depending on the nature of the error it may be necessary to reverse the operation of errors.Wrap to retrieve the original error for inspection. Any error value which implements this interface can be inspected by `errors.Cause`.
```go
type causer interface {
Cause() error
}
```
`errors.Cause` will recursively retrieve the topmost error which does not implement `causer`, which is assumed to be the original cause. For example:
```go
switch err := errors.Cause(err).(type) {
case *MyError:
// handle specifically
default:
// unknown error
}
```
[Read the package documentation for more information](https://godoc.org/github.com/pkg/errors).

// Package errors provides simple error handling primitives.
//
// The traditional error handling idiom in Go is roughly akin to
//
// if err != nil {
// return err
// }
//
// which applied recursively up the call stack results in error reports
// without context or debugging information. The errors package allows
// programmers to add context to the failure path in their code in a way
// that does not destroy the original value of the error.
//
// Adding context to an error
//
// The errors.Wrap function returns a new error that adds context to the
// original error by recording a stack trace at the point Wrap is called,
// and the supplied message. For example
//
// _, err := ioutil.ReadAll(r)
// if err != nil {
// return errors.Wrap(err, "read failed")
// }
//
// If additional control is required the errors.WithStack and errors.WithMessage
// functions destructure errors.Wrap into its component operations of annotating
// an error with a stack trace and an a message, respectively.
//
// Retrieving the cause of an error
//
// Using errors.Wrap constructs a stack of errors, adding context to the
// preceding error. Depending on the nature of the error it may be necessary
// to reverse the operation of errors.Wrap to retrieve the original error
// for inspection. Any error value which implements this interface
//
// type causer interface {
// Cause() error
// }
//
// can be inspected by errors.Cause. errors.Cause will recursively retrieve
// the topmost error which does not implement causer, which is assumed to be
// the original cause. For example:
//
// switch err := errors.Cause(err).(type) {
// case *MyError:
// // handle specifically
// default:
// // unknown error
// }
//
// causer interface is not exported by this package, but is considered a part
// of stable public API.
//
// Formatted printing of errors
//
// All error values returned from this package implement fmt.Formatter and can
// be formatted by the fmt package. The following verbs are supported
//
// %s print the error. If the error has a Cause it will be
// printed recursively
// %v see %s
// %+v extended format. Each Frame of the error's StackTrace will
// be printed in detail.
//
// Retrieving the stack trace of an error or wrapper
//
// New, Errorf, Wrap, and Wrapf record a stack trace at the point they are
// invoked. This information can be retrieved with the following interface.
//
// type stackTracer interface {
// StackTrace() errors.StackTrace
// }
//
// Where errors.StackTrace is defined as
//
// type StackTrace []Frame
//
// The Frame type represents a call site in the stack trace. Frame supports
// the fmt.Formatter interface that can be used for printing information about
// the stack trace of this error. For example:
//
// if err, ok := err.(stackTracer); ok {
// for _, f := range err.StackTrace() {
// fmt.Printf("%+s:%d", f)
// }
// }
//
// stackTracer interface is not exported by this package, but is considered a part
// of stable public API.
//
// See the documentation for Frame.Format for more details.

The `new` command creates a new empty migration template using the following pattern `<current time>-<name>.sql`.
The `up` command applies all available migrations. By contrast, `down` will only apply one migration by default. This behavior can be changed for both by using the `-limit` parameter.
The `redo` command will unapply the last migration and reapply it. This is useful during development, when you're writing migrations.
