# envy
[![Build Status](https://travis-ci.org/gobuffalo/envy.svg?branch=master)](https://travis-ci.org/gobuffalo/envy)
Envy makes working with ENV variables in Go trivial.
* Get ENV variables with default values.
* Set ENV variables safely without affecting the underlying system.
* Temporarily change ENV vars; useful for testing.
* Map all of the key/values in the ENV.
* Loads .env files (by using [godotenv](https://github.com/joho/godotenv/))
* More!
## Installation
```text
$ go get -u github.com/gobuffalo/envy
```
## Usage
```go
func Test_Get(t *testing.T) {
r := require.New(t)
r.NotZero(os.Getenv("GOPATH"))
r.Equal(os.Getenv("GOPATH"), envy.Get("GOPATH", "foo"))
r.Equal("bar", envy.Get("IDONTEXIST", "bar"))
}
func Test_MustGet(t *testing.T) {
r := require.New(t)
r.NotZero(os.Getenv("GOPATH"))
v, err := envy.MustGet("GOPATH")
r.NoError(err)
r.Equal(os.Getenv("GOPATH"), v)
_, err = envy.MustGet("IDONTEXIST")
r.Error(err)
}
func Test_Set(t *testing.T) {
r := require.New(t)
_, err := envy.MustGet("FOO")
r.Error(err)
envy.Set("FOO", "foo")
r.Equal("foo", envy.Get("FOO", "bar"))
}
func Test_Temp(t *testing.T) {
r := require.New(t)
_, err := envy.MustGet("BAR")
r.Error(err)
envy.Temp(func() {
envy.Set("BAR", "foo")
r.Equal("foo", envy.Get("BAR", "bar"))
_, err = envy.MustGet("BAR")
r.NoError(err)
})
_, err = envy.MustGet("BAR")
r.Error(err)
}
```
## .env files support
Envy now supports loading `.env` files by using the [godotenv library](https://github.com/joho/godotenv/).
That means one can use and define multiple `.env` files which will be loaded on-demand. By default, no env files will be loaded. To load one or more, you need to call the `envy.Load` function in one of the following ways:
```go
envy.Load() // 1
envy.Load("MY_ENV_FILE") // 2
envy.Load(".env", ".env.prod") // 3
envy.Load(".env", "NON_EXISTING_FILE") // 4
// 5
envy.Load(".env")
envy.Load("NON_EXISTING_FILE")
// 6
envy.Load(".env", "NON_EXISTING_FILE", ".env.prod")
```
1. Will load the default `.env` file
2. Will load the file `MY_ENV_FILE`, **but not** `.env`
3. Will load the file `.env`, and after that will load the `.env.prod` file. If any variable is redefined in `. env.prod` it will be overwritten (will contain the `env.prod` value)
4. Will load the `.env` file and return an error as the second file does not exist. The values in `.env` will be loaded and available.
5. Same as 4
6. Will load the `.env` file and return an error as the second file does not exist. The values in `.env` will be loaded and available, **but the ones in** `.env.prod` **won't**.

# github.com/gobuffalo/envy Stands on the Shoulders of Giants
github.com/gobuffalo/envy does not try to reinvent the wheel! Instead, it uses the already great wheels developed by the Go community and puts them all together in the best way possible. Without these giants, this project would not be possible. Please make sure to check them out and thank them for all of their hard work.
Thank you to the following **GIANTS**:

# github.com/gobuffalo/packd
This is a collection of interfaces designed to make using [github.com/gobuffalo/packr](https://github.com/gobuffalo/packr) easier, and to make the transition between v1 and v2 as seamless as possible.
They can, and should, be used for testing, alternate Box implementations, etc...
## Installation
```bash
$ go get -u -v github.com/gobuffalo/packd
```
## Memory Box
The [`packd#MemoryBox`](https://godoc.org/github.com/gobuffalo/packd#MemoryBox) is a complete, thread-safe, implementation of [`packd#Box`](https://godoc.org/github.com/gobuffalo/packd#Box)

# github.com/gobuffalo/packd Stands on the Shoulders of Giants
github.com/gobuffalo/packd does not try to reinvent the wheel! Instead, it uses the already great wheels developed by the Go community and puts them all together in the best way possible. Without these giants, this project would not be possible. Please make sure to check them out and thank them for all of their hard work.
Thank you to the following **GIANTS**:

# packr (v1)
[![GoDoc](https://godoc.org/github.com/gobuffalo/packr?status.svg)](https://godoc.org/github.com/gobuffalo/packr)
## Packr has been updated to `v2`! Please read the `./v2/README.md` file for more details.
---
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
To install Packr utility
```text
$ go get -u github.com/gobuffalo/packr/packr
```
To get the dependency
```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, or an error if it doesn't exist:
html, err := box.FindString("index.html")
// Get the []byte representation of a file, or an error if it doesn't exist:
html, err := box.FindBytes("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, err := box.FindString("admin/index.html")
if err != nil {
log.Fatal(err)
}
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 receives 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/#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.
---
## Building/Moving a portable release
When it comes to building multiple releases you typically want that release to be built in a specific directory.
For example: `./releases`
However, because passing a `.go` file requires absolute paths, we must compile the release in the appropriate absolute path.
```bash
GOOS=linux GOARCH=amd64 packr build
```
Now your `project_name` binary will be built at the root of your project dir. Great!
All that is left to do is to move that binary to your release dir:
Linux/macOS/Windows (bash)
```bash
mv ./project_name ./releases
```
Windows (cmd):
```cmd
move ./project_name ./releases
```
Powershell:
```powershell
Move-Item -Path .\project_name -Destination .\releases\
```
If you _target_ for Windows when building don't forget that it's `project_name.exe`
Now you can make multiple releases and all of your needed static files will be available!
#### Summing it up:
Example Script for building to 3 common targets:
```bash
GOOS=darwin GOARCH=amd64 packr build && mv ./project_name ./releases/darwin-project_name \
&& GOOS=linux GOARCH=amd64 packr build && mv ./project_name ./releases/linux-project_name \
&& GOOS=windows GOARCH=386 packr build && mv ./project_name.exe ./releases/project_name.exe \
&& packr clean
```
---
## 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.

# GoDotEnv [![Build Status](https://travis-ci.org/joho/godotenv.svg?branch=master)](https://travis-ci.org/joho/godotenv) [![Build status](https://ci.appveyor.com/api/projects/status/9v40vnfvvgde64u4?svg=true)](https://ci.appveyor.com/project/joho/godotenv) [![Go Report Card](https://goreportcard.com/badge/github.com/joho/godotenv)](https://goreportcard.com/report/github.com/joho/godotenv)
A Go (golang) port of the Ruby dotenv project (which loads env vars from a .env file)
From the original Library:
> Storing configuration in the environment is one of the tenets of a twelve-factor app. Anything that is likely to change between deployment environmentssuch as resource handles for databases or credentials for external servicesshould be extracted from the code into environment variables.
>
> But it is not always practical to set environment variables on development machines or continuous integration servers where multiple projects are run. Dotenv load variables from a .env file into ENV when the environment is bootstrapped.
It can be used as a library (for loading in env for your own daemons etc) or as a bin command.
There is test coverage and CI for both linuxish and windows environments, but I make no guarantees about the bin version working on windows.
## Installation
As a library
```shell
go get github.com/joho/godotenv
```
or if you want to use it as a bin command
```shell
go get github.com/joho/godotenv/cmd/godotenv
```
## Usage
Add your application configuration to your `.env` file in the root of your project:
```shell
S3_BUCKET=YOURS3BUCKET
SECRET_KEY=YOURSECRETKEYGOESHERE
```
Then in your Go app you can do something like
```go
package main
import (
"github.com/joho/godotenv"
"log"
"os"
)
func main() {
err := godotenv.Load()
if err != nil {
log.Fatal("Error loading .env file")
}
s3Bucket := os.Getenv("S3_BUCKET")
secretKey := os.Getenv("SECRET_KEY")
// now do something with s3 or whatever
}
```
If you're even lazier than that, you can just take advantage of the autoload package which will read in `.env` on import
```go
import _ "github.com/joho/godotenv/autoload"
```
While `.env` in the project root is the default, you don't have to be constrained, both examples below are 100% legit
```go
_ = godotenv.Load("somerandomfile")
_ = godotenv.Load("filenumberone.env", "filenumbertwo.env")
```
If you want to be really fancy with your env file you can do comments and exports (below is a valid env file)
```shell
# I am a comment and that is OK
SOME_VAR=someval
FOO=BAR # comments at line end are OK too
export BAR=BAZ
```
Or finally you can do YAML(ish) style
```yaml
FOO: bar
BAR: baz
```
as a final aside, if you don't want godotenv munging your env you can just get a map back instead
```go
var myEnv map[string]string
myEnv, err := godotenv.Read()
s3Bucket := myEnv["S3_BUCKET"]
```
... or from an `io.Reader` instead of a local file
```go
reader := getRemoteFile()
myEnv, err := godotenv.Parse(reader)
```
... or from a `string` if you so desire
```go
content := getRemoteFileContent()
myEnv, err := godotenv.Unmarshal(content)
```
### Command Mode
Assuming you've installed the command as above and you've got `$GOPATH/bin` in your `$PATH`
```
godotenv -f /some/path/to/.env some_command with some args
```
If you don't specify `-f` it will fall back on the default of loading `.env` in `PWD`
### Writing Env Files
Godotenv can also write a map representing the environment to a correctly-formatted and escaped file
```go
env, err := godotenv.Unmarshal("KEY=value")
err := godotenv.Write(env, "./.env")
```
... or to a string
```go
env, err := godotenv.Unmarshal("KEY=value")
content, err := godotenv.Marshal(env)
```
## Contributing
Contributions are most welcome! The parser itself is pretty stupidly naive and I wouldn't be surprised if it breaks with edge cases.
*code changes without tests will not be accepted*
1. Fork it
2. Create your feature branch (`git checkout -b my-new-feature`)
3. Commit your changes (`git commit -am 'Added some feature'`)
4. Push to the branch (`git push origin my-new-feature`)
5. Create new Pull Request
## Releases
Releases should follow [Semver](http://semver.org/) though the first couple of releases are `v1` and `v1.1`.
Use [annotated tags for all releases](https://github.com/joho/godotenv/issues/30). Example `git tag -a v1.2.1`
## CI
Linux: [![Build Status](https://travis-ci.org/joho/godotenv.svg?branch=master)](https://travis-ci.org/joho/godotenv) Windows: [![Build status](https://ci.appveyor.com/api/projects/status/9v40vnfvvgde64u4)](https://ci.appveyor.com/project/joho/godotenv)
## Who?
The original library [dotenv](https://github.com/bkeepers/dotenv) was written by [Brandon Keepers](http://opensoul.org/), and this port was done by [John Barton](https://johnbarton.co/) based off the tests/fixtures in the original library.

// Safe encodings
//
// Module paths appear as substrings of file system paths
// (in the download cache) and of web server URLs in the proxy protocol.
// In general we cannot rely on file systems to be case-sensitive,
// nor can we rely on web servers, since they read from file systems.
// That is, we cannot rely on the file system to keep rsc.io/QUOTE
// and rsc.io/quote separate. Windows and macOS don't.
// Instead, we must never require two different casings of a file path.
// Because we want the download cache to match the proxy protocol,
// and because we want the proxy protocol to be possible to serve
// from a tree of static files (which might be stored on a case-insensitive
// file system), the proxy protocol must never require two different casings
// of a URL path either.
//
// One possibility would be to make the safe encoding be the lowercase
// hexadecimal encoding of the actual path bytes. This would avoid ever
// needing different casings of a file path, but it would be fairly illegible
// to most programmers when those paths appeared in the file system
// (including in file paths in compiler errors and stack traces)
// in web server logs, and so on. Instead, we want a safe encoding that
// leaves most paths unaltered.
//
// The safe encoding is this:
// replace every uppercase letter with an exclamation mark
// followed by the letter's lowercase equivalent.
//
// For example,
// github.com/Azure/azure-sdk-for-go -> github.com/!azure/azure-sdk-for-go.
// github.com/GoogleCloudPlatform/cloudsql-proxy -> github.com/!google!cloud!platform/cloudsql-proxy
// github.com/Sirupsen/logrus -> github.com/!sirupsen/logrus.
//
// Import paths that avoid upper-case letters are left unchanged.
// Note that because import paths are ASCII-only and avoid various
// problematic punctuation (like : < and >), the safe encoding is also ASCII-only
// and avoids the same problematic punctuation.
//
// Import paths have never allowed exclamation marks, so there is no
// need to define how to encode a literal !.
//
// Although paths are disallowed from using Unicode (see pathOK above),
// the eventual plan is to allow Unicode letters as well, to assume that
// file systems and URLs are Unicode-safe (storing UTF-8), and apply
// the !-for-uppercase convention. Note however that not all runes that
// are different but case-fold equivalent are an upper/lower pair.
// For example, U+004B ('K'), U+006B ('k'), and U+212A ('' for Kelvin)
// are considered to case-fold to each other. When we do add Unicode
// letters, we must not assume that upper/lower are the only case-equivalent pairs.
// Perhaps the Kelvin symbol would be disallowed entirely, for example.
// Or perhaps it would encode as "!!k", or perhaps as "(212A)".
//
// Also, it would be nice to allow Unicode marks as well as letters,
// but marks include combining marks, and then we must deal not
// only with case folding but also normalization: both U+00E9 ('é')
// and U+0065 U+0301 ('e' followed by combining acute accent)
// look the same on the page and are treated by some file systems
// as the same path. If we do allow Unicode marks in paths, there
