# Description
this PR adds the `path add` command to
`crates/nu-utils/standard_library/std.nu`
- this comes from frequent questions over on the discord server, about
how to add directories to the `PATH`
- this is greatly inspired from the [original
`path-add`](https://discord.com/channels/601130461678272522/615253963645911060/1081206660816699402)
from @melMass
- allows to prepend and append a variable number of directories to the
`PATH`
- i've added a description with an example
- i've added tests in `crates/nu-utils/standard_library/tests.nu` that
hopefully covers all the features
# User-Facing Changes
`path add` can now be used from `std.nu`
# Tests + Formatting
the tests pass with
```bash
nu crates/nu-utils/standard_library/tests.nu
```
# After Submitting
```bash
$nothing
```
# Description
we've discussed a bit about the location of the standard library in the
#standard-library channel of the discord server => **the previous
location, `crates/nu-utils/src/sample_config/`, was a bit confusing**
- is `std.nu` a config file, just as `default_config.nu` or
`default_env.nu`?
- what is this `tests.nu` file inside the `sample_config/`?
in this PR, i propose moving the standard library to
`crates/nu-utils/standard_library/` for a few reasons:
- `std.nu` is not a config file, so it should not be next to config
files in a `sample_config/` directory
- `tests.nu` is confusing if mixed with other unrelated files
- `crates/nu-utils/` appears to be a good place for the standard library
as it is meant to be a tool for `nushell`
- i thought it would be strange to have `std.nu` inside
`crates/nu-utils/src/` as this directory is generally filled with `rust`
files, right?
these are the reasons why i choose to propose
`crates/nu-utils/standard_library/` 😋
# User-Facing Changes
the standard library is now used with
```bash
use crates/nu-utils/standard_library/std.nu
```
and the tests are run with
```bash
nu crates/nu-utils/standard_library/tests.nu
```
# Tests + Formatting
```bash
$nothing
```
# After Submitting
