+# GoDotEnv ![CI](https://github.com/joho/godotenv/workflows/CI/badge.svg) [![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](https://github.com/bkeepers/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 environments–such as resource handles for databases or credentials for external services–should 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
+
+go >= 1.17
+```shell
+go install github.com/joho/godotenv/cmd/godotenv@latest
+```
+
+go < 1.17
+```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 (
+    "log"
+    "os"
+
+    "github.com/joho/godotenv"
+)
+
+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)
+```
+
+### Precedence & Conventions
+
+Existing envs take precedence of envs that are loaded later.
+
+The [convention](https://github.com/bkeepers/dotenv#what-other-env-files-can-i-use)
+for managing multiple environments (i.e. development, test, production)
+is to create an env named `{YOURAPP}_ENV` and load envs in this order:
+
+```go
+env := os.Getenv("FOO_ENV")
+if "" == env {
+  env = "development"
+}
+
+godotenv.Load(".env." + env + ".local")
+if "test" != env {
+  godotenv.Load(".env.local")
+}
+godotenv.Load(".env." + env)
+godotenv.Load() // The Original .env
+```
+
+If you need to, you can also use `godotenv.Overload()` to defy this convention
+and overwrite existing envs instead of only supplanting them. Use with caution.
+
+### 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`
+
+By default, it won't override existing environment variables; you can do that with the `-o` flag.
+
+### 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 welcome, but with some caveats.
+
+This library has been declared feature complete (see [#182](https://github.com/joho/godotenv/issues/182) for background) and will not be accepting issues or pull requests adding new functionality or breaking the library API.
+
+Contributions would be gladly accepted that:
+
+* bring this library's parsing into closer compatibility with the mainline dotenv implementations, in particular [Ruby's dotenv](https://github.com/bkeepers/dotenv) and [Node.js' dotenv](https://github.com/motdotla/dotenv)
+* keep the library up to date with the go ecosystem (ie CI bumps, documentation changes, changes in the core libraries)
+* bug fixes for use cases that pertain to the library's purpose of easing development of codebases deployed into twelve factor environments
+
+*code changes without tests and references to peer dotenv implementations 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`
+
+## 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.
