# Description
I always wondered why the module env vars `CURRENT_FILE`, `FILE_PWD`,
`PROCESS_PATH` weren't available in the source command. I tried to add
them here. I think it could be helpful but I'm not sure. I'm also not
sure this hack is what we should do but I thought I'd put it out there
for fun.
Thoughts?
### Run Module (works as it did before)
```nushell
❯ open test_module.nu
def main [] {
print $"$env.CURRENT_FILE = ($env.CURRENT_FILE?)"
print $"$env.FILE_PWD = ($env.FILE_PWD?)"
print $"$env.PROCESS_PATH = ($env.PROCESS_PATH?)"
}
❯ nu test_module.nu
$env.CURRENT_FILE = /Users/fdncred/src/nushell/test_module.nu
$env.FILE_PWD = /Users/fdncred/src/nushell
$env.PROCESS_PATH = test_module.nu
```
### Use Module (works as it did before)
```nushell
❯ open test_module2.nu
export-env {
print $"$env.CURRENT_FILE = ($env.CURRENT_FILE?)"
print $"$env.FILE_PWD = ($env.FILE_PWD?)"
print $"$env.PROCESS_PATH = ($env.PROCESS_PATH?)"
}
❯ use test_module2.nu
$env.CURRENT_FILE = /Users/fdncred/src/nushell/test_module.nu
$env.FILE_PWD = /Users/fdncred/src/nushell
$env.PROCESS_PATH =
```
### Sourced non-module script (this is the new part)
> [!NOTE]
> Note: We intentionally left out PROCESS_PATH since it's supposed to
> to work like argv[0] in C, which is the name of the program being
executed.
> Since we're not executing a program, we don't need to set it.
```nushell
❯ open test_source.nu
print $"$env.CURRENT_FILE = ($env.CURRENT_FILE?)"
print $"$env.FILE_PWD = ($env.FILE_PWD?)"
print $"$env.PROCESS_PATH = ($env.PROCESS_PATH?)"
❯ source test_source.nu
$env.CURRENT_FILE = /Users/fdncred/src/nushell/test_source.nu
$env.FILE_PWD = /Users/fdncred/src/nushell
$env.PROCESS_PATH =
```
Also, what is PROCESS_PATH even supposed to be?

# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.
Make sure you've run and fixed any issues with these commands:
- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use toolkit.nu; toolkit test stdlib"` to run the
tests for the standard library
> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr
> ```

# After Submitting
<!-- If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
