+# 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 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.
+
+This is a fork of [joho/godotenv](https://github.com/joho/godotenv) focussing on `.env` file support by the compose specification
+
+
+
+To run linter and tests, please install [Earthly](https://earthly.dev/get-earthly) and run:
+```sh
+earthly +all
+```

-# 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 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
-```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.
