![Swift build status](https://github.com/juri/dotenvy/actions/workflows/build.yml/badge.svg)

DotEnvy is a dotenv file parser for Swift. It allows you to load values from an `.env` file, similar to the libraries

for [node.js], [Python], [Ruby], [Rust][Rust][^1] etc.

[^1]: I accidentally used the same name they use; apologies!

DotEnvy supports multiline strings and variable substitution.

[node.js]: https://github.com/motdotla/dotenv

[Python]: https://pypi.org/project/python-dotenv/

[Ruby]: https://github.com/bkeepers/dotenv

[Rust]: https://docs.rs/dotenvy/latest/dotenvy/

## Documentation

For more detailed syntax examples and API documentation visit DotEnvy's [documentation] on Swift Package Index.

## Supported format

The dotenv format does not have a specification, but this library supports the common features. The syntax

resembles Bash. Examples:

```sh

KEY=value

KEY2 = "quoted value"

 

 KEY3= unquoted value "with" quotes inside

# comment

KEY4 ='quoted value referring to ${KEY3}' # trailing comment

KEY5=unquoted value referring to ${KEY4}

KEY6="multiline

string"

```

## Error reporting

DotEnvy has helpful error reporting on syntax errors.

```swift

let source = #"""

KEY="VALUE

"""#

do {

    _ = try DotEnvironment.parse(string: source)

} catch let error as ParseErrorWithLocation {

    let formatted = error.formatError(source: source)

    print(formatted)

}

```

outputs

```

   1: KEY="VALUE

                ^

Error on line 1: Unterminated quote

```

## Command Line

There's also a command line tool, `dotenv-tool`. It supports checking dotenv files for syntax errors and converting

them to JSON. To install, run:

```sh

swift build -c release

cp .build/release/dotenv-tool /usr/local/bin

```
