# osenv

Apply .env files to shell environments!

## What is it

Given a .env like this:

```env
DB_USER=admin
DB_PASSWORD=changeme
```

it will generate scripts for bash (and likely other *sh) and powershell, like:

### Powershell

Example output:

```ps1
$env:DB_USER = "admin"
$env:DB_PASSWORD = "changeme"
```

### *nix shell

Example output:

```sh
export DB_USER=admin
export DB_PASSWORD=changeme
```

## Installation

### Requirements

- Rust + Cargo (tested w/ 1.37)
- A compatible shell (powershell/bash/zsh)

### Compilation

```sh
cargo install --path .
```

This will install `osenv-bin` in your cargo bin folder (don't forget to add it to `PATH`!)
You can already use it, with some caveats (having to specify the full string, like `osenv-bin | iex`), but you should just make a function and add it to your shell's profile file.

### Add to profile

If you're using sh/bash/zsh, add this to your .bashrc/.zshrc/etc:

```sh
osenv() {
    RES=$(osenv-bin $@)
    if [ $? -eq 0 ]; then
        eval $RES
    else
        echo $RES
    fi
}
```

If you're using Powershell, add this to your `$profile`:

```ps1
function osenv {
    $cmd = osenv-bin @Args
    if ($?) {
        $cmd | Invoke-Expression
    }
    else {
        Write-Output $cmd
    }
}
```

If you rather have them as script to source, you can find them in `scripts` in this repo.

If you want to enhance osenv to add a special "add to profile" command, or make some scripts that do (easy in powershell, not so much in the shell world), contributions are highly appreciated!
