# Description
Was original asked here:
https://github.com/nushell/nushell/pull/8405#issuecomment-1465062652
Make it easier to extend standard library with submodules.
(For a new submodule called `xx.nu` the tests can be written in
`test_xx.nu`).
Test discovery is implemented.
# User-Facing Changes
There are no user-facing changes.
# Tests + Formatting
Tests are updated.
There is no `nufmt` now.

Should close#8444.
# Description
as asked by @presidento, i've used a generic command to run the tests.
i've also transformed the "a concrete example" sections into quote
blocks to make them stand out less.
not sure about that one, please tell me what you think 😋
i think a small example is always helpfull, maybe some work has to be
done to make it better 💪
# User-Facing Changes
hopefully a slightly clearer README for the standard library

It is a common pattern to add message to assert.
Also the error message was not so helpful. (See the difference in the
documentation)

# Description
Prototype replacement for `enter`, `n`, `p`, `exit` built-ins
implemented as scripts in standard library.
MVP-level capabilities (rough hack), for feedback please. Not intended
to merge and ship as is.

# User-Facing Changes
New command in standard library
```nushell
〉use ~/src/rust/nushell/crates/nu-utils/standard_library/dirs.nu
---------------------------------------------- /home/bobhy ----------------------------------------------
〉help dirs
module dirs.nu -- maintain list of remembered directories + navigate them
todo:
* expand relative to absolute paths (or relative to some prefix?)
* what if user does `cd` by hand?
Module: dirs
Exported commands:
add (dirs add), drop, next (dirs next), prev (dirs prev), show (dirs show)
This module exports environment.
---------------------------------------------- /home/bobhy ----------------------------------------------
〉dirs add ~/src/rust/nushell /etc ~/.cargo
-------------------------------------- /home/bobhy/src/rust/nushell --------------------------------------
〉dirs next 2
------------------------------------------- /home/bobhy/.cargo -------------------------------------------
〉dirs show

# Tests + Formatting
Haven't even looked at stdlib `tests.nu` yet.
Other todos:
* address module todos.
* integrate into std lib, rather than as standalone module. Somehow
arrange for `use .../standard_library/std.nu` to load this module
without having to put all the source in `std.nu`?
* Maybe command should be `std dirs ...`?
* what else do `enter` and `exit` do that this should do? Then deprecate
those commands.
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 -A
clippy::needless_collect` to check that you're using the standard code
style
- `cargo test --workspace` to check that all tests pass

# 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
```

# 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
```
