# Env parser
[](https://crates.io/crates/env_parser)
[](https://github.com/jasperav/env_parser/actions)
This crate will parse an `.env` file. By implementing the `Transformer` trait, you can
customize the behaviour after processing key value pair in the env file. Comments are preserved and
can be used on top of the Rust mapped property.
For convenience there is a feature `to_lazy_static` that will automatically map key value pairs into a `lazy_static` block.
Check `assert_test.rs` and `assert_test_lazy.rs` for examples.
## Usage
Add the following to your Cargo.toml...
```toml
[dependencies]
env_parser = "*"
```
Ideally, create `build.rs` file and call the `env_parser` reader from the build file, so that your mapped Rust file
is always in sync with your `.env` file.
