Closes#5436
When I opened this issue more than a year ago, I mainly wanted the
following capacity: easily access the full env and have the hability to
update it when a new version of `nushell` comes out.
With this PR I can now do the following:
```nu
source-env ~/.config/nushell/defaults/env.nu
source ~/.config/nushell/defaults/config.nu
# Update nushell default config & env file (run this after a version update)
def update-defaults [] {
config env --default | save -f ~/.config/nushell/defaults/env.nu
config nu --default | save -f ~/.config/nushell/defaults/config.nu
}
```
Which is more than enough for me. Along with `nushell` respecting the
XDG spec on macOS (`dirs-next` should be banned for CLI tools on macOS),
this should be one of the last hurdle before fully switching for me!

Are the docs for commands generated automatically or do I need to make a

there are any :)
# Description
Magenta wasn't being interpreted correctly. note that `bg:
magenta_reverse attr: b` showed up as white. This was because it was
missing from the lookup and it was defaulting to white.

# Description
Fixes: #10450
This pr differentiating between `--x: bool` and `--x`
Here are examples which demostrate difference between them:
```nushell
def a [--x: bool] { $x };
a --x # not allowed, you need to parse a value to the flag.
a # it's allowed, and the value of `$x` is false, which behaves the same to `def a [--x] { $x }; a`
```
For boolean flag with default value, it works a little bit different to
#10450 mentioned:
```nushell
def foo [--option: bool = false] { $option }
foo # output false
foo --option # not allowed, you need to parse a value to the flag.
foo --option true # output true
```
# User-Facing Changes
After the pr, the following code is not allowed:
```nushell
def a [--x: bool] { $x }; a --x
```
Instead, you have to pass a value to flag `--x` like `a --x false`. But
bare flag works in the same way as before.
## Update: one more breaking change to help on #7260
```
def foo [--option: bool] { $option == null }
foo
```
After the pr, if we don't use a boolean flag, the value will be `null`
instead of `true`. Because here `--option: bool` is treated as a flag
rather than a switch

# Description
While reviewing #10350 I noticed that a `HashSet<usize>` was used to
deduplicate the incoming rows, which are then sorted after cloning to a
separate `Vec`. This sounds like a candidate for a `BTreeSet` which
guarantees the ordering.
In the process I removed some dead code.
- Use `BTreeSet` instead of `HashSet`
- Remove dead `skip` logic
- Use `BTreeSet` directly in `NthIterator`
- Consume `BTreeSet` through `Peekable<IntoIter>`
# Description
This PR should close#10085
Maps `DirectoryNotFound` errors to `FileNotFound`. All other errors are
left unchanged.
# User-Facing Changes
This means a user will see `FileNotFound` instead of `DirectoryNotFound`
which is more meaning full to the user.
# Description
This new command `into value` is a command that tries to infer the type
of data you have in a table. It converts each cell to a string and then
runs a set of regular expressions on that string. This was mostly
cobbled together after looking at how polars does similar things. The
regular expressions were taken straight form polars and tweaked.

It's definitely not perfect. There are ways it will fail because on
regular expressions not working on all formats. My hope is that people
will pick this up and add more regular expressions and if there are
problems with the existing ones, change them. This is meant as a
"starter command" with easy entry for newcomers that are looking to chip
in and help out.
Also, some tests probably need to be added to ensure what we have now
doesn't break with updates.

# Description
Fixes: #10410
So the following script is possible:
```nushell
def a [b: any = null] { let b = ($b | default "default_b"); }
a "given_b"
```
## About the change
When parsing signature, and nushell meets something like `a: any`, it
force the parser to treat `a` as `any` type. This is what
`arg_explicit_type` means, it's only set when we goes into
`ParseMode::TypeMode`, and it will be reset to `false` if the token goes
to next argument.
so, when we have something like this: `def a [b: any = null] { $b }`,
the type of `$b` won't be overwritten.
But if we have something like this: `def a [b = null] { $b }`, the type
of `$b` is not annotated, so we make it to be `nothing`(which is the
type of null)

# Description
`str replace --string` has been deprecated in
https://github.com/nushell/nushell/pull/10038 and should be removed
before 0.85.
this PR removes the `--string` option from `str replace` completely.
# User-Facing Changes
`str replace --string` will no longer work and will give an error
instead of a warning.

# Description
We made the decision that our floating point type should be referred to
as `float` over `decimal`.
Commands were updated by #9979 and #10320
Now make the internal codebase consistent in referring to this data type
as `float`.
Work for #10332
# User-Facing Changes
`decimal` has been removed as a type name/symbol.
Instead of
```nushell
def foo [bar: decimal] decimal -> decimal {}
```
use
```nushell
def foo [bar: float] float -> float {}
```
Potential effect of `SyntaxShape`'s `Display` implementation now also
referring to `float` instead of `decimal`
# Details
- Rename `SyntaxShape::Decimal` to `Float`
- Update `Display for SyntaxShape` to `float`
- Update error message + fn name in dataframe code
- Fix docs in command examples
- Rename tests that are float specific
- Update doccomment on `SyntaxShape`
- Update comment in script
# Tests + Formatting
Updates the names of some tests
# Description
this commit adds the handling of Value::List when BodyType is Json
it also adds the corresponding test (trying to send a list)

This PR is in reference to #10215.
This PR changes `select` to work even if multiple equal items were
provided.
This would previously error, but now works
```nushell
let arg = [ 1 a ]
[[a b c]; [1 2 3] [4 5 6] [7 8 9]]
| select $arg
```
# User-Facing Changes
Nothing too radical, just experience improvements. Users won't need to
pass the values through `unique` beforehand.
# Description
Currently we support "multiplication" of strings, resulting in a terse
way to repeat a particular string.
This can have unintended side effects when dealing with mixed data (e.g.
after parsing data that is not all numbers).
Furthermore as we frequently fall-back to strings while parsing source
code, this introduced a runaway edge case in const evaluation (#10212)
Work for #10233
## Details
- Remove python-like string multiplication.
- Workaround for indentation
- This should probably be addressed with a purpose built command
- Remove special const-eval error test
# User-Facing Changes
**Major breaking change!**
`"string" * 42` will stop working. (This was used for example in the
stdlib)
We should bless a good alternative before landing this

Elide the reference for `Copy` type (`usize`)
Use the canonical deref where possible.
* `&Box` -> `&`
* `&String` -> `&str`
* `&PathBuf` -> `&Path`
Skips the ctrl-C handler for now.
# Description
The pythonism that multiplying a scalar integer with a list results in a
repeated concatenation of the list, is ambiguous with other possible
interpretations and thus actively harmful to clear semantics in nushell.
Another possible reading of this scalar/vector product would be trying
to perform elementwise multiplication with the scalar.
Before we bless this alternative as a more reasonable design the best
course of action is to remove this pythonism.
Work related to #10233
# User-Facing Changes
Breaking change as this turns `int * list` or `list * int` into hard
errors.
# Tests + Formatting
Remove the associated test
# Description
This PR tried to add a few more columns to the Linux `ps -l` command.
Those columns are:
* start_time
* user_id
* priority
* process_threads
There are a few that I left commented out that could be added but the
screen was beginning to look crowded. So, I left out:
* group_id
* session_id
* tgp_id (which could be helpful for eventual job control)
And there's like 100 more things that could be added that didn't seem
especially useful right now.

# Description
This changes `echo` to work more closely to what users of other shells
would expect:
* when redirected, `echo` works as before and sends values through the
pipeline
* when not redirected, `echo` will print values to the screen/terminal
# User-Facing Changes
A standalone `echo` now will print to the terminal, if not redirected.
The `echo` command is no longer const eval-able, as it will now print to
the terminal in some cases.

fixes#8551
# Description
Use `open::commands` function to get list of command available for
starting given path. run commands directly, providing environment, until
one of them is successful.
example of output if start was not successful:
```
~\code\nushell> start ..\nustart\a.myext 09/12/2023 01:37:55 PM
Error: nu:🐚:external_command
× External command failed
╭─[entry #1:1:1]
1 │ start ..\nustart\a.myext
· ─────────┬────────
· ╰── No command found to start with this path
╰────
help: Try different path or install appropriate command
Command `cmd /c start "" "..\nustart\a.myext"` failed with exit code: 1
```
# User-Facing Changes
`start` command now provides environment to the external command. This
is how it worked in `nu 0.72`, see linked issue.
# Tests + Formatting
`start` command didn't have any tests and this PR does not add any.
Integration-level tests will require setup specific to OS and
potentially change global environment on testing machine. For unit-level
test it is possible to test `try_commands` function. But is still runs
external commands, and robust test will require apriori knowledge which
commands are necessary successful to run and which are not.
# Description
Similar to #9979
# User-Facing Changes
`random decimal` will now raise a warning and can be removed in an
upcoming release.
New command is named `random float`
# Tests + Formatting
Tests updated and improved.
# Description
We keep "into decimal" for a release and warn through a message that it
will be removed in 0.86.
All tests are updated to use `into float`
# User-Facing Changes
`into decimal` raises a deprecation warning, will be removed soon.
Use `into float` as the new functionally identical command instead.

# Description
This generally makes for nicer APIs, as you are not forced to use an
existing allocation covering the full `String`.
Some exceptions remain where the underlying type requirements favor it.
# User-Facing Changes
None
# Description
This removes pipeline element profiling. This could be a useful feature,
but pipeline elements are going to be the most sensitive to in terms of
performance, as `eval_block` and how pipelines are built is one of the
hot loops inside of the eval engine.

# Description
This PR adds new flag `--keep-order/-k` for the `par_each` filter. This
flag keeps sequence of output same as the order of input.
Output without the flag:
```nu
> 1..6 | par-each {|n| $n * 2 }
╭────╮
│ 4 │
│ 10 │
│ 2 │
│ 8 │
│ 12 │
│ 6 │
╰────╯
```
Output with the `--keep-order` flag:
```nu
> 1..6 | par-each --keep-order {|n| $n * 2 }
╭────╮
│ 2 │
│ 4 │
│ 6 │
│ 8 │
│ 10 │
│ 12 │
╰────╯
```
I think the presence of this flag is justified, since:
- Much easier to use than `.. | enumerate | par-each {|p| update item
..} | sort-by index | get item`
- Faster, as it uses internally parallel sorting in the same thread pool
A note about naming: it may conflict with `--keep-empty/-k` flag of the
`each` filter if the same feature will be used in `par-each`, so maybe
it needs some other name.

# Description
Fixes#10300 , where using variables didnt work with `ucp` as it was
only expecting a `Expr::FilePath`.
Before: (from the issue)
```
❯ ucp -r $var $folder
Error: × Missing file operand
╭─[entry #40:1:1]
1 │ ucp -r $var $folder
· ─┬─
· ╰── Missing file operand
╰────
help: Please provide source and destination paths
```
Now:
```
`ucp -r $var $folder`
# success
```
Also added the test to ensure its working:) . Oh, and I tweaked again
slightly the messages on two tests because now the whole `path` is
printed rather than `a`. Say:
```
#before
`cp a a` --> 'a' and 'a' are the same file
# now
`cp a a` --> /home/current/location/a and /home/current/location/a are the same file
```

# Description
two cool things about the `where` command
- it's versatile enough to allow creating a case-insensitive version of
itself
- it does not require the explicit use of a closure

case-insensitively and without an explicite closure.
# User-Facing Changes

This PR is in relation to #10215
# Description
This PR introduces `reject` to receive list of columns or rows as
argument.
This change is similar to change of `select` and the code used is
similar.
# User-Facing Changes
The user will be able to pass a list as rejection arguments.
```nushell
let arg = [ type size ]
[[name type size]; [ cargo.toml file 20mb ] [ Cargo.lock file 20mb] [src dir 100mb]] | reject $arg
```
# Description
This PR fixes `reject` failing when providing row items in ascending
order.
# User-Facing Changes
users can now `reject` multiple rows independently of each other.
```nushell
let foo = [[a b]; [ 1 2] [3 4] [ 5 6]]
# this will work independant of the order
print ($foo | reject 2 1)
print ($foo | reject 1 2)

Supercedes https://github.com/nushell/nushell/pull/10196
# Description
After reading
https://github.com/nushell/nushell/pull/10196#issuecomment-1703986359 I
added a signpost from `keybindings listen` to `input listen`
When I initially tried `input listen` it always immediately returned
with:
```
╭───────┬────────╮
│ type │ focus │
│ event │ gained │
╰───────┴────────╯
```
I added an example to `input listen --help` to suggest only listening to
key events
Initially I also included a `result` but it prints as:
```
╭───────────┬───────────────╮
│ type │ key │
│ key_type │ char │
│ code │ c │
│ modifiers │ [list 1 item] │
╰───────────┴───────────────╯
```
rather than:
```
╭───────────┬───────────────────────────────╮
│ type │ key │
│ key_type │ char │
│ code │ c │
│ │ ╭───┬───────────────────────╮ │
│ modifiers │ │ 0 │ keymodifiers(control) │ │
│ │ ╰───┴───────────────────────╯ │
╰───────────┴───────────────────────────────╯
```
so I removed it.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
* Example describing how to use `input list --types [key]` to listen for
keybindings.
* Signpost pointing at `use std input; input list --types [key]` from
`keybindings list`.
## After merging
It is probably worth:
a) signposting to the keybindings section of the book from both of these
subcommands (like I did in
https://github.com/nushell/nushell/pull/10193),
b) giving an example in the book of how to take the output from `input
listen --types [key]` and format it for including in `config nu`
c) there are not currently any examples in
crates/nu-utils/src/sample_config/default_config.nu for keybindings with
multiple modifiers. Should I add alt+backspace-in-macos-vscode as an
example (gets translated to `{ modifier: control_alt keycode: char_h }`
for historical reasons)?

# Description
Hi. Basically, this is a continuation of the work that @fdncred started.
Given some nice discussions on #9463 , and [merged uutils
PR](https://github.com/uutils/coreutils/pull/5152) from @tertsdiepraam
we have decided to give the `cp` command the `crawl` stage as it was
named.
> [!NOTE]
Given that the `uutils` crate has not made the release for the merged
PR, just make sure you checkout latest and put it in the required place
to make this PR work.
The aim of this PR is for is to see how to move forward using `uutils`
crate. In order to getting this started, I have made the current
`nushell cp tests` pass along with some extra ones I copied over from
the `uutils` repo.
With all of that being said, things that would be nice to decide, and
keep working on:
Crawl:
- Handling of certain `named` flags, with their long and short
forms(e.g. --update, --reflink, --preserve, etc), and using default
values. Maybe `-u` can already have a `default_missing_value`.
- Should we maybe just support one single option `switch` flags (see
`--backup` in code) as a contrast to the other named args.
- Complete test coverage from `uutils`. They had > 100 tests, and I
could only port like 12 as they are a bit time consuming given they
cannot be straight up copy pasted. Maybe we do not need all >100, but
maybe the more relevant to what we want.
- Refactor this code
Walk:
- Non fatal errors on `copy` from `utils`. Currently it just sends it to
stdout but errors have no span
- Better integration
An added possibility is the addition of `SyntaxShape::OneOf()` for
`Named` arguments which was briefly mentioned in the discord server, but
that is still to be decided. This could greatly improve some of the
integration. This would enable something like `cp --preserve [all
timestamp]` or `cp --preserve all` to both work.
I did not want to keep holding on this, and wait till I was happy with
the code because I think its nice if everyone can start up and suggest
refactors, but the main important part now was getting it out the door,
as if I take my sweet time this will take way longer 😛

# Description
Apparently some strftime formats are already localized and when you
"double localize" them, they don't work. This PR fixes that so that %x
%X %r %c don't go through the localization step.
Example: %x %X
### Before
```nushell
❯ date now | format date "%x %X %p"
09/08/2023 08 AM
```
### After
```nushell
❯ date now | format date "%x %X %p"
09/08/23 08:09:14 AM
```
I started to make one format_datetime to rule them all but one returns a
string and one returns a value. If we convert to the string, we lose the
nice error messages. If we change to value, more code has to be changed
elsewhere. So, I decided to just leave two functions.

# Description
before this PR,
```nushell
> $.a.b | describe
cell path
```
which feels inconsistent with the `cell-path` type annotation, like in
```nushell
> def foo [x: cell-path] { $x | describe }; foo $.a.b
cell path
```
this PR changes the name of the "cell path" type from `cell path` to
`cell-path`
# User-Facing Changes
`cell path` is now `cell-path` in the output of `describe`.
this might be a breaking change in some scripts.
same goes with
- `list stream` -> `list-stream`
- `match pattern` -> `match-pattern`
# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- ⚫ `toolkit test`
- ⚫ `toolkit test stdlib`
this PR adds a new `cell_path_type` test to make sure it stays equal to
`cell-path` in the future.

I think this is `sleep`'s specific issue, it's because it always return
a `Value::nothing` where it's interrupted by `ctrl-c`.
To fix the issue, I'd propose to make it returns Err(ShellError)
This is how it behaves:
```nushell
❯ sleep 5sec; echo "hello!"
^CError: nu:🐚:sleep_breaked
× Sleep is breaked.
❯ sleep 5sec; ^echo "hello!"
^CError: nu:🐚:sleep_breaked

Currently on Android, there are warnings about unused variables. This PR
fixes that with more conditional guards for the unused variables.
Additionally, in #10013, @kubouch gave feedback in [the last
PR](https://github.com/nushell/nushell/pull/10013#pullrequestreview-1596828128)
that it was unwieldy to repeat
```rust
#[cfg(all(
feature = "trash-support",
not(target_os = "android"),
not(target_os = "ios")
))]
```
# Description
This PR makes `append`/`prepend` more consistent, in particular, it allows you to
work with ranges. Previously, you couldn't append a list by range:
```nu
> 0..1 | append 2..4
╭──────╮
│ 0 │
│ 1 │
│ 2..4 │
╰──────╯
```
Now it works:
```nu
> 0..1 | append 2..4
╭───╮
│ 0 │
│ 1 │
│ 2 │
│ 3 │
│ 4 │
╰───╯
```
# User-Facing Changes
If someone needs the old behavior, then it can be obtained like this:
```nu
> 0..1 | append [2..4]
╭──────╮
│ 0 │
│ 1 │
│ 2..4 │
╰──────╯

Fix https://github.com/nushell/nushell/issues/10136
# Description
Current nushell only handle path containing '*' as match pattern and
treat '?' as just normal path.
This pr makes path containing '?' is also processed as pattern.
🔴 **Concerns: Need to design/comfirm a consistent rule to handle
dirs/files with '?' in their names.**
Currently:
- if no dir has exactly same name with pattern, it will print the list
of matched directories
- if pattern exactly matches an empty dir's name, it will just print the
empty dir's content ( i.e. `[]`)
- if pattern exactly matches an dir's name, it will perform pattern
match and print all the dir contains
e.g.
```bash
mkdir src
ls s?c
```
| name | type | size | modified |
| ---- | ---- | ------ | --------------------------------------------- |
| src | dir | 1.1 KB | Tue, 29 Aug 2023 07:39:41 +0900 (9 hours ago) |

# Description
This updates most crates to 0.27 `crossterm`.
To do so we need the most recent `ratatui`
`reedline` can now update as well.
See https://github.com/nushell/reedline/pull/625
Sadly this introduces some crate duplication again as there are some
other dependency updates.
Furthermore we have another crate depending on 0.26.1 crossterm
(`comfy-table` that some how gets pulled in by polars)
# User-Facing Changes
2 additional mouse events detected by `input listen`

None
# Description
As part of the refactor to split spans off of Value, this moves to using
helper functions to create values, and using `.span()` instead of
matching span out of Value directly.
Hoping to get a few more helping hands to finish this, as there are a
lot of commands to update :)

close#8074
I attempted to refactor the "input" command. The reason for this is that
the current implementation of the "input" command lacks consistency for
different options. For instance, some parts use `std::io::stdin` while
others use `crossterm::event::read`.
In this pull request, I have made changes to use crossterm consistently:
- Detection of the -u option is now done using `crossterm`'s
`KeyCode::Char`.
- The current input is displayed when using `crossterm` for input (it
won't be displayed when -s is present).
- Ctrl-C triggers SIGINT.
# User-Facing Changes
Users can interrupt "input" with ctrl-c.
They relied on the `nu_plugin_inc` but where behind a feature flag that
isn't actually defined anywhere. These tests of `update` or `upsert`
shouldn't really depend on `inc` so I decided to remove them outright as
they haven't been used to exercise the commands under test.
As described in Issue #8670, removed `pipeline()` wherever its argument
contained no line breaks.

I moved hook to *nu_cmd_base* instead of *nu_cli* because it will enable
other developers to continue to use hook even if they decide to write
their on cli or NOT depend on nu-cli
Then they will still have the hook functionality because they can
include nu-cmd-base
# Description
This PR names the hooks as they're executing so that you can see them
with debug statements. So, at the beginning of `eval_hook()` you could
put a dbg! or eprintln! to see what hook was executing. It also shows up
in View files.
### Before - notice item 14 and 25
### After - The hooks are now named (14 & 25)
Curiosity, on my mac, the display_output hook fires 3 times before
anything else. Also, curious is that the value if the display_output, is
not what I have in my config but what is in the default_config. So,
there may be a bug or some shenanigans going on somewhere with hooks.

# Description
This doesn't really do much that the user could see, but it helps get us
ready to do the steps of the refactor to split the span off of Value, so
that values can be spanless. This allows us to have top-level values
that can hold both a Value and a Span, without requiring that all values
have them.
We expect to see significant memory reduction by removing so many
unnecessary spans from values. For example, a table of 100,000 rows and
5 columns would have a savings of ~8megs in just spans that are almost
always duplicated.

# Description
This PR creates a new `Record` type to reduce duplicate code and
possibly bugs as well. (This is an edited version of #9648.)
- `Record` implements `FromIterator` and `IntoIterator` and so can be
iterated over or collected into. For example, this helps with
conversions to and from (hash)maps. (Also, no more
`cols.iter().zip(vals)`!)
- `Record` has a `push(col, val)` function to help insure that the
number of columns is equal to the number of values. I caught a few
potential bugs thanks to this (e.g. in the `ls` command).
- Finally, this PR also adds a `record!` macro that helps simplify
record creation. It is used like so:
```rust
record! {
"key1" => some_value,
"key2" => Value::string("text", span),
"key3" => Value::int(optional_int.unwrap_or(0), span),
"key4" => Value::bool(config.setting, span),
}
```
Since macros hinder formatting, etc., the right hand side values should
be relatively short and sweet like the examples above.
Where possible, prefer `record!` or `.collect()` on an iterator instead
of multiple `Record::push`s, since the first two automatically set the
record capacity and do less work overall.
# User-Facing Changes
Besides the changes in `nu-protocol` the only other breaking changes are
to `nu-table::{ExpandedTable::build_map, JustTable::kv_table}`.

# Description
I'm trying to fix the problems mentioned in the issue. It's my first
attempt in Rust. Please let me know if there are any problems.
# User-Facing Changes
- The `--little-endian` option dropped, replaced with `--endian`.
- Add the `--compact` option to the `into binary` command.
- `into int` accepts binary input
Closes#9910 FOR REAL this time.
I had fixed the issue on Linux but not Windows. Context:
https://github.com/nushell/nushell/issues/9910#issuecomment-1689308886
I've tested this PR successfully on Windows, Linux, and macOS by running
`watch . {|a,b| print $a; print $b}` and confirming that it prints once
when I change a file in the current directory.
# Description
This PR removes `record` processing from the `length` command. It just
doesn't make sense to try and get the length of a record. This PR also
removes the `--column` parameter. If you want to list or count columns,
you could use `$table | columns` or `$table | columns | length`.

https://github.com/nushell/nushell/pull/9773 introduced constants to
modules and allowed to export them, but only within one level. This PR:
* allows recursive exporting of constants from all submodules
* fixes submodule imports in a list import pattern
* makes sure exported constants are actual constants
Should unblock https://github.com/nushell/nushell/pull/9678
### Example:
```nushell
module spam {
export module eggs {
export module bacon {
export const viking = 'eats'
}
}
}
use spam
print $spam.eggs.bacon.viking # prints 'eats'
use spam [eggs]
print $eggs.bacon.viking # prints 'eats'
use spam eggs bacon viking
print $viking # prints 'eats'
```
### Limitation 1:
Considering the above `spam` module, attempting to get `eggs bacon` from
`spam` module doesn't work directly:
```nushell
use spam [ eggs bacon ] # attempts to load `eggs`, then `bacon`
use spam [ "eggs bacon" ] # obviously wrong name for a constant, but doesn't work also for commands
```
Workaround (for example):
```nushell
use spam eggs
use eggs [ bacon ]
print $bacon.viking # prints 'eats'
```
I'm thinking I'll just leave it in, as you can easily work around this.
It is also a limitation of the import pattern in general, not just
constants.
### Limitation 2:
`overlay use` successfully imports the constants, but `overlay hide`
does not hide them, even though it seems to hide normal variables
successfully. This needs more investigation.

# Description
This PR tries to fix `into datetime`. The problem was that it didn't
support many input formats and the `--format` was clunky. `--format` is
still a bit clunky but can work. The big change here is that it first
tries to use `dtparse` to convert text into datetime.
### Before
```nushell
❯ '20220604' | into datetime
Thu, 01 Jan 1970 00:00:00 +0000 (53 years ago)
```
### After
```nushell
❯ '20220604' | into datetime
Sat, 04 Jun 2022 00:00:00 -0500 (a year ago)
```
## Supported Input Formats
`dtparse` should support all these formats. Taken from their

# Description
This PR updates some `Example` tests so that they work again. The only
one I couldn't figure out is the one in the `filter` command. It should
work but does not. However, I left the test in because it's valuable, it
just has a `None` result. I'd like to fix this but I'm not sure how.
