# Description
For years, Nushell has used `let-env` to set a single environment
variable. As our work on scoping continued, we refined what it meant for
a variable to be in scope using `let` but never updated how `let-env`
would work. Instead, `let-env` confusingly created mutations to the
command's copy of `$env`.
So, to help fix the mental model and point people to the right way of
thinking about what changing the environment means, this PR removes
`let-env` to encourage people to think of it as updating the command's
environment variable via mutation.
Before:
```
let-env FOO = "BAR"
```
Now:
```
$env.FOO = "BAR"
```
It's also a good reminder that the environment owned by the command is
in the `$env` variable rather than global like it is in other shells.
# User-Facing Changes
BREAKING CHANGE BREAKING CHANGE
This completely removes `let-env FOO = "BAR"` so that we can focus on
`$env.FOO = "BAR"`.

# Description
When the directory stack contains only two directories, then std dirs
drop
used to misbehave and (essentially) drop the other directory, instead of
dropping the current directory.
This is fixed by always cd'ing for std dirs drop.
Before:
/tmp〉enter ..
/〉dexit
/〉
After:
/tmp〉enter ..
/〉dexit
/tmp〉
Additionally, I propose to explain the relevant environment variables a
bit
more thoroughly.
# User-Facing Changes
- Fix bug in dexit (std dirs drop) when two directories are remaining
# Tests + Formatting
Added a regression test. Made the existing test easier to understand.
# Description
Test runner now performs following actions in order to run tests:
* Module file is opened
* Public function with random name is added to the source code, this
function calls user-specified private function
* Modified module file is saved under random name in $nu.temp-path
* Modified module file is imported in subprocess, injected function is
called by the test runner
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
* Test functions no longer need to be exported
* test functions no longer need to reside in separate test_ files
* setup and teardown renamed to before-each and after-each respectively
* before-all and after-all functions added that run before all tests in
given module. This matches the behavior of test runners used by other
languages such as JUnit/TestNG or Mocha

# Description
I have (hopefully) simplified the `log.nu` internal structure and added
customizable log format for all `log` commands
# User-Facing Changes
- [x] Replaced constants with env records for:
- ansi (newly added)
- log level
- prefix
- short prefix
- [x] Added `format` argument to all log commands
- [x] Assertions for (not) equality (equal, not equal, greater,
lesser...) now put left and right values inside `'` quotes, so the
assertions for strings are more meaningful
- [x] Documented the %-formatting of log messages

related to the namespace bullet point in
- https://github.com/nushell/nushell/issues/8450
# Description
this was the last module of the standard library with a broken
namespace, this PR takes care of this.
- `run-tests` has been moved to `std/mod.nu`
- `std/testing.nu` has been moved to `std/assert.nu`
- the namespace has been fixed
- `assert` is now called `main` and used in all the other `std assert`
commands
- for `std assert length` and `std assert str contains`, in order not to
shadow the built-in `length` and `str contains` commands, i've used
`alias "core ..." = ...` to (1) define `foo` in `assert.nu` and (2)
still use the builtin `foo` with `core foo` (replace `foo` by `length`
or `str contains`)
- tests have been fixed accordingly
# User-Facing Changes
one can not use
```
use std "assert equal"
```
anymore because `assert ...` is not exported from `std`.
`std assert` is now a *real* module.
# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- ⚫ `toolkit test`
- ⚫ `toolkit test stdlib`
# After Submitting
```
$nothing
```
# Notes for reviewers
to test this, i think the easiest is to
- run `toolkit test stdlib` and see all the tests pass
- run `cargo run -- -n` and try `use std assert` => are all the commands
available in scope?

Fixes https://github.com/nushell/nushell/issues/9229.
Supersedes #9234
The reported problem was that `shells` list of active shells (a.k.a `std
dirs show` would show an inaccurate active
working directory if user changed it via `cd` command.
The fix here is for the `std dirs` module to let `$env.PWD` mask the
active slot of `$env.DIRS_LIST`. The user is free to invoke CD (or write
to `$env.PWD`) and `std dirs show` will display that as the active
working directory.
When user changes the active slot (via `n`, `p`, `add` or `drop`) `std
dirs` remembers the then current PWD in the about-to-be-vacated active
slot in `$env.DIRS_LIST`, so it is there if you come back to that slot.

# Description
A new command to simplify assertions for `false`.
The name is just a draft, though I could not come up with a better name.
I have rejected `assert false`, because I would have to rename `assert`
to `assert true` which would break the compatibility and worsen the
shell experience of the good old `assert`.
Another idea I have rejected was something like `assert_false` to keep
it consistent with the naming convention of our stdlib.
I am open to suggestions :)

# Description
this pr adds the following commands to `std iter`
- `iter find-index` -> returns the index of the first element that
matches the predicate or `-1` if none
- `iter flat-map` -> maps a closure to each nested structure and
flattens the result
- `iter zip-with` -> zips two structures and applies a closure to each
of the zips
it also fixes some \*\*very minor\*\* inconsistencies in the module
Related to:
- #8311
- #8353
# Description
with the new `$nu.startup-time` from #8353 and as mentionned in #8311,
we are now able to fully move the `nushell` banner from the `rust`
source base to the standard library.
this PR
- removes all the `rust` source code for the banner
- rewrites a perfect clone of the banner to `std.nu`, called `std
banner`
- call `std banner` from `default_config.nu`
# User-Facing Changes
see the demo: https://asciinema.org/a/566521
- no config will show the banner (e.g. `cargo run --release --
--no-config-file`)
- a custom config without the `if $env.config.show_banner` block and no
call to `std banner` would never show the banner
- a custom config with the block and `config.show_banner = true` will
show the banner
- a custom config with the block and `config.show_banner = false` will
NOT show the banner
# Tests + Formatting
a new test line has been added to `tests.nu` to check the length of the
`std banner` output.
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`

# Description
As in other testing frameworks, the `setup` runs before every test case,
and the `teardown` after that. A context can be created in `setup`,
which will be in the `$in` variable in the test cases, and in the
`teardown`. The `teardown` is called regardless of the test is passed,
skipped, or failed.
For example:
```nushell
use std.nu *
export def setup [] {
log debug "Setup is running"
{msg: "This is the context"}
}
export def teardown [] {
log debug $"Teardown is running. Context: ($in)"
}
export def test_assert_pass [] {
log debug $"Assert is running. Context: ($in)"
}
export def test_assert_skip [] {
log debug $"Assert is running. Context: ($in)"
assert skip
}
export def test_assert_fail_skipped_by_default [] {
log debug $"Assert is running. Context: ($in)"
assert false
}
```
