Now the `input list` command, when nothing is selected, will return a
null instead of empty string or an empty list.
Resolves#10909.
# User-Facing Changes
`input list` now returns a `null` when nothing is selected.
# Description
Pretty much all operations/commands in Nushell assume that the column
names/keys in a record and thus also in a table (which consists of a
list of records) are unique.
Access through a string-like cell path should refer to a single column
or key/value pair and our output through `table` will only show the last
mention of a repeated column name.
```nu
[[a a]; [1 2]]
╭─#─┬─a─╮
│ 0 │ 2 │
╰───┴───╯
```
While the record parsing already either errors with the
`ShellError::ColumnDefinedTwice` or silently overwrites the first
occurence with the second occurence, the table literal syntax `[[header
columns]; [val1 val2]]` currently still allowed the creation of tables
(and internally records with more than one entry with the same name.
This is not only confusing, but also breaks some assumptions around how
we can efficiently perform operations or in the past lead to outright
bugs (e.g. #8431 fixed by #8446).
This PR proposes to make this an error.
After this change another hole which allowed the construction of records
with non-unique column names will be plugged.
## Parts
- Fix `SE::ColumnDefinedTwice` error code
- Remove previous tests permitting duplicate columns
- Deny duplicate column in table literal eval
- Deny duplicate column in const eval
- Deny duplicate column in `from nuon`
# User-Facing Changes
`[[a a]; [1 2]]` will now return an error:
```
Error: nu:🐚:column_defined_twice
× Record field or table column used twice
╭─[entry #2:1:1]
1 │ [[a a]; [1 2]]
· ┬ ┬
· │ ╰── field redefined here
· ╰── field first defined here
╰────
```
this may under rare circumstances block code from evaluating.
Furthermore this makes some NUON files invalid if they previously
contained tables with repeated column names.
# Tests + Formatting
Added tests for each of the different evaluation paths that materialize
tables.
# Description
This change allows `compact` to also compact things with empty strings,
empty lists, and empty records if the `--empty` switch is used. Let's
add a quality-of-life improvement here to just compact all this mess. If
this is a bad idea, please cite examples demonstrating why.

# Description
Previously `group-by` returned a record containing each group as a
column. This data layout is hard to work with for some tasks because you
have to further manipulate the result to do things like determine the
number of items in each group, or the number of groups. `transpose` will
turn the record returned by `group-by` into a table, but this is
expensive when `group-by` is run on a large input.
In a discussion with @fdncred [several
workarounds](https://github.com/nushell/nushell/discussions/10462) to
common tasks were discussed, but they seem unsatisfying in general.
Now when `group-by --to-table` is used a table is returned with the
columns "groups" and "items" making it easier to do things like count
the number of groups (`| length`) or count the number of items in each
group (`| each {|g| $g.items | length`)
# User-Facing Changes
* `group-by` returns a `table` with "group" and "items" columns instead
of a `record` with one column per group name
# Tests + Formatting
Tests for `group-by` were updated
# After Submitting
* No breaking changes were made. The new `--to-table` switch should be
added automatically to the [`group-by`
documentation](https://www.nushell.sh/commands/docs/group-by.html)
# Description
Use `record!` macro instead of defining two separate `vec!` for `cols`
and `vals` when appropriate.
This visually aligns the key with the value.
Further more you don't have to deal with the construction of `Record {
cols, vals }` so we can hide the implementation details in the future.
## State
Not covering all possible commands yet, also some tests/examples are
better expressed by creating cols and vals separately.
# User/Developer-Facing Changes
The examples and tests should read more natural. No relevant functional
change
# Bycatch
Where I noticed it I replaced usage of `Value` constructors with
`Span::test_data()` or `Span::unknown()` to the `Value::test_...`
constructors. This should make things more readable and also simplify
changes to the `Span` system in the future.
# Description
as we can see in the [documentation of
`str.to_lowercase`](https://doc.rust-lang.org/std/primitive.str.html#method.to_lowercase),
not only ASCII symbols have lower and upper variants.
- `str upcase` uses the correct method to convert the string
7ac5a01e2f/crates/nu-command/src/strings/str_/case/upcase.rs (L93)
- `str downcase` incorrectly converts only ASCII characters
7ac5a01e2f/crates/nu-command/src/strings/str_/case/downcase.rs (L124)
this PR uses `str.to_lower_case` instead of `str.to_ascii_lowercase` in
`str downcase`.
# User-Facing Changes
- upcase still works fine
```nushell
~ l> "ὀδυσσεύς" | str upcase

looking at the [Wax documentation about

especially
> therefore does not read directory trees from the file system when a
directory matches an [exhaustive glob
expression](https://docs.rs/wax/latest/wax/trait.Pattern.html#tymethod.is_exhaustive)
> **Important**
> in the following of this PR description, i talk about *pruning* and a
`--prune` option, but this has been changed to *exclusion* and
`--exclude` after a discussion with @fdncred.
this looks like a *pruning* operation to me, right? 😮
i wanted to make the `glob` option `--not` clearer about that, because
> -n, --not <List(String)> - Patterns to exclude from the results
from `help glob` is not very explicit about whether the search is pruned
when entering a directory matching a pattern in `--not` or just removing
it from the output 😕
## changelog
this PR proposes to rename the `glob --not` option to `glob --prune` and
make it's documentation more explicit 😋
## benchmarking
to support the *pruning* behaviour put forward above, i've run a
benchmark
1. define two closures to compare the behaviour between removing
patterns manually or using `--not`
```nushell
let where = {
[.*/\.local/.*, .*/documents/.*, .*/\.config/.*]
| reduce --fold (glob **) {|pat, acc| $acc | where $it !~ $pat}
| length
}
```
```nushell
let not = { glob ** --not [**/.local/**, **/documents/**, **/.config/**] | length }
```
2. run the two to make sure they give similar results
```nushell
> do $where
33424
```
```nushell
> do $not
33420
```
👌
3. measure the performance
```nushell
use std bench
```
```nushell
> bench --verbose --pretty --rounds 25 $not
44ms 52µs 285ns +/- 977µs 571ns
```
```nushell
> bench --verbose --pretty --rounds 5 $where
1sec 250ms 187µs 99ns +/- 8ms 538µs 57ns
```
👉 we can see that the results are (almost) the same but
`--not` is much faster, looks like pruning 😋
# User-Facing Changes
- `--not` will give a warning message but still work
- `--prune` will work just as `--not` without warning and with a more
explicit doc
- `--prune` and `--not` at the same time will give an error
# Tests + Formatting
this PR fixes the examples of `glob` using the `--not` option.

Implements `whoami` using the `whoami` command from uutils as backend.
This is a draft because it depends on
https://github.com/uutils/coreutils/pull/5310 and a new release of
uutils needs to be made (and the paths in `Cargo.toml` should be
updated). At this point, this is more of a proof of concept 😄
Additionally, this implements a (simple and naive) conversion from the
uutils `UResult` to the nushell `ShellError`, which should help with the
integration of other utils, too. I can split that off into a separate PR
if desired.
I put this command in the "platform" category. If it should go somewhere
else, let me know!
The tests will currently fail, because I've used a local path to uutils.
Once the PR on the uutils side is merged, I'll update it to a git path
so that it can be tested and runs on more machines than just mine.

New `whoami` command. This might break some users who expect the system
`whoami` command. However, the result of this new command should be very
close, just with a nicer help message, at least for Linux users. The
default `whoami` on Windows is quite different from this implementation:

# Description
Currently the following command is broken:
```nushell
echo a o+e> 1.txt
```
It's because we don't redirect output of `echo` command. This pr is
trying to fix it.
# Description
- this PR should close#10819
# User-Facing Changes
Behaviour is similar to pre 0.86.0 behaviour of the cp command and
should as such not have a user-facing change, only compared to the
current version, were the option is readded.
# After Submitting
I guess the documentation will be automatically updated and as this
feature is no further highlighted, probably, no more work will be needed
here.
# Considerations
coreutils actually allows a third option:
```
pub enum UpdateMode {
// --update=`all`,
ReplaceAll,
// --update=`none`
ReplaceNone,
// --update=`older`
// -u
ReplaceIfOlder,
}
```
namely `ReplaceNone`, which I have not added. Also I think that
specifying `--update 'abc'` is non functional.
# Description
Fixes: #10830
The issue happened during lite-parsing, when we want to put a
`LiteElement` to a `LitePipeline`, we do nothing if relative redirection
target is empty.
So the command `echo aaa o> | ignore` will be interpreted to `echo aaa |
ignore`.
This pr is going to check and return an error if redirection target is
empty.
# User-Facing Changes
## Before
```
❯ echo aaa o> | ignore # nothing happened
```
## After
```nushell

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
Users can pattern match against a `null` literal.
# Description
`from tsv` and `from csv` both support a `--flexible` flag. This flag
can be used to "allow the number of fields in records to be variable".
Previously, a record's invariant that `rec.cols.len() == rec.vals.len()`
could be broken during parsing. This can cause runtime errors as in
#10693. Other commands, like `select` were also affected.
The inconsistencies are somewhat hard to see, as most nushell code
assumes an equal number of columns and values.
# Before
### Fewer values than columns
```nushell
> let record = (echo "one,two\n1" | from csv --flexible | first)
# There are two columns
> $record | columns | to nuon
[one, two]
# But only one value
> $record | values | to nuon
[1]
# And printing the record doesn't show the second column!
> $record | to nuon
{one: 1}
```
### More values than columns
```nushell
> let record = (echo "one,two\n1,2,3" | from csv --flexible | first)
# There are two columns
> $record | columns | to nuon
[one, two]
# But three values
> $record | values | to nuon
[1, 2, 3]
# And printing the record doesn't show the third value!
> $record | to nuon
{one: 1, two: 2}
```
# After
### Fewer values than columns
```nushell
> let record = (echo "one,two\n1" | from csv --flexible | first)
# There are two columns
> $record | columns | to nuon
[one, two]
# And a matching number of values
> $record | values | to nuon
[1, null]
# And printing the record works as expected
> $record | to nuon
{one: 1, two: null}
```
### More values than columns
```nushell
> let record = (echo "one,two\n1,2,3" | from csv --flexible | first)
# There are two columns
> $record | columns | to nuon
[one, two]
# And a matching number of values
> $record | values | to nuon
[1, 2]
# And printing the record works as expected
> $record | to nuon
{one: 1, two: 2}
```

Using the `--flexible` flag with `from csv` and `from tsv` will not
result in corrupted record state.

Reverts nushell/nushell#10812
This goes back to a version of `regex` and its dependencies that is
shared with a lot of our other dependencies. Before this we did not
duplicate big dependencies of `regex` that affect binary size and
compile time.
As there is no known bug or security problem we suffer from, we can wait
on receiving the performance improvements to `regex` with the rest of
our `regex` dependents.
r? @fdncred
Last one, I hope. At least short of completely redesigning `registry
query`'s interface. (Which I wouldn't implement without asking around
first.)
# Description
User-Facing Changes has the general overview. Inline comments provide a
lot of justification on specific choices. Most of the type conversions
should be reasonably noncontroversial, but expanding `REG_EXPAND_SZ`
needs some justification. First, an example of the behavior there:
```shell
> # release nushell:
> version | select version commit_hash | to md --pretty
| version | commit_hash |
| ------- | ---------------------------------------- |
| 0.85.0 | a6f62e05ae |
> registry query --hkcu Environment TEMP | get value
%USERPROFILE%\AppData\Local\Temp
> # with this patch:
> version | select version commit_hash | to md --pretty
| version | commit_hash |
| ------- | ---------------------------------------- |
| 0.86.1 | 0c5a4c991f |
> registry query --hkcu Environment TEMP | get value
C:\Users\CAD\AppData\Local\Temp
> # Microsoft CLI tooling behavior:
> ^pwsh -c `(Get-ItemProperty HKCU:\Environment).TEMP`
C:\Users\CAD\AppData\Local\Temp
> ^reg query HKCU\Environment /v TEMP
HKEY_CURRENT_USER\Environment
TEMP REG_EXPAND_SZ %USERPROFILE%\AppData\Local\Temp
```
As noted in the inline comments, I'm arguing that it makes more sense to
eagerly expand the %EnvironmentString% placeholders, as none of
Nushell's path functionality will interpret these placeholders. This
makes the behavior of `registry query` match the behavior of pwsh's
`Get-ItemProperty` registry access, and means that paths (the most
common use of `REG_EXPAND_SZ`) are actually usable.
This does *not* break nu_script's
[`update-path`](https://github.com/nushell/nu_scripts/blob/main/sourced/update-path.nu);
it will just be slightly inefficient as it will not find any
`%Placeholder%`s to manually expand anymore. But also, note that
`update-path` is currently *wrong*, as a path including
`%LocalAppData%Low` is perfectly valid and sometimes used (to go to
`Appdata\LocalLow`); expansion isn't done solely on a path segment
basis, as is implemented by `update-path`.
I believe that the type conversions implemented by this patch are
essentially always desired. But if we want to keep `registry query`
"pure", we could easily introduce a `registry get`[^get] which does the
more complete interpretation of registry types, and leave `registry
query` alone as doing the bare minimum. Or we could teach `path expand`
to do `ExpandEnvironmentStringsW`. But REG_EXPAND_SZ being the odd one
out of not getting its registry type semantics decoded by `registry
query` seems wrong.
[^get]: This is the potential redesign I alluded to at the top. One
potential change could be to make `registry get Environment` produce
`record<Path: string, TEMP: string, TMP: string>` instead of `registry
query`'s `table<name: string, value: string, type: string>`, the idea
being to make it feel as native as possible. We could even translate
between Nu's cell-path and registry paths -- cell paths with spaces do
actually work, if a bit awkwardly -- or even introduce lazy records so
the registry can be traversed with normal data manipulation ... but that
all seems a bit much.
# User-Facing Changes
- `registry query`'s produced `value` has changed. Specifically:
- ❗ Rows `where type == REG_EXPAND_SZ` now expand `%EnvironmentVarable%`
placeholders for you. For example, `registry query --hkcu Environment
TEMP | get value` returns `C:\Users\CAD\AppData\Local\Temp` instead of
`%USERPROFILE%\AppData\Local\Temp`.
- You can restore the old behavior and preserve the placeholders by
passing a new `--no-expand` switch.
- Rows `where type == REG_MULTI_SZ` now provide a `list<string>` value.
They previously had that same list, but `| str join "\n"`.
- Rows `where type == REG_DWORD_BIG_ENDIAN` now provide the correct
numeric value instead of a byte-swapped value.
- Rows `where type == REG_QWORD` now provide the correct numeric
value[^sign] instead of the value modulo 2<sup>32</sup>.
- Rows `where type == REG_LINK` now provide a string value of the link
target registry path instead of an internal debug string representation.
(This should never be visible, as links should be transparently
followed.)
- Rows `where type =~ RESOURCE` now provide a binary value instead of an
internal debug string representation.
[^sign]: Nu's `int` is a signed 64-bit integer. As such, values >=
2<sup>63</sup> will be reported as their negative two's compliment
value. This might sometimes be the correct interpretation -- the
registry does not distinguish between signed and unsigned integer values
-- but regedit and pwsh display all values as unsigned.
# Description
Remove the `clean_string` hack used in `registry query`.
This was a workaround for a [bug][gentoo90/winreg-rs#52] in winreg which
has since [been fixed][edf9eef] and released in [winreg v0.12.0].
winreg now properly displays strings in RegKey's Display impl instead of
outputting their debug representation. We remove our `clean_string` such
that registry entries which happen to start/end with `"` or contain `\\`
won't get mangled. This is very important for entries in UNC path format
as those begin with a double backslash.

# Description
it appears `size` is a command that operates on `string`s only and gives
the user information about the chars, graphemes and bytes of a string.
this looks like a command that should be a subcommand to `str` 😏
this PR
- adds `str size`
- deprecates `size`
`size` is planned to be removed in 0.88
# User-Facing Changes
`str size` can be used for the same result as `size`.

because some people look into `unfold` already (myself included lol) and
there will be 4 weeks with that new command which has a decent section
in the release note, i fear that
https://github.com/nushell/nushell/pull/10770 is a bit too brutal,
removing `unfold` without any warning...
this PR brings `unfold` back to life.
the `unfold` command will have a deprecation warning and will be removed
in 0.88.

Add `--ignore-errors` flag to reject.
This is a PR in reference to #10215 as select has the flag, but reject
hasn't
user can now add `-i` or `--ignore-errors` flag to turn every cell path
into option.
```nushell
> let arg = [0 5 a c]
> [[a b];[1 2] [3 4] [5 6]] | reject $a | to nuon

(squashed version of #10557, clean commit history and review thread)
Fixes#10571, also potentially: #10364, #10211, #9558, #9310,
# Description
Changes processing of arguments to filesystem commands that are source
paths or globs.
Applies to `cp, cp-old, mv, rm, du` but not `ls` (because it uses a
different globbing interface) or `glob` (because it uses a different
globbing library).
The core of the change is to lookup the argument first as a file and
only glob if it is not. That way,
a path containing glob metacharacters can be referenced without glob
quoting, though it will have to be single quoted to avoid nushell
parsing.
Before: A file path that looks like a glob is not matched by the glob
specified as a (source) argument and takes some thinking about to
access. You might say the glob pattern shadows a file with the same
spelling.
```

> cp --verbose 'a[[]bc[]]d' dest
copied /home/bobhy/src/rust/work/r4/a[bc]d to /home/bobhy/src/rust/work/r4/dest/a[bc]d
```
Before_2: if file has glob metachars but isn't a valid pattern, user
gets a confusing error:
```
> touch 'a[b'
> cp 'a[b' dest
Error: × Pattern syntax error near position 30: invalid range pattern
╭─[entry #13:1:1]
1 │ cp 'a[b' dest
· ──┬──
· ╰── invalid pattern
╰────
```
After: Args to cp, mv, etc. are tried first as literal files, and only
as globs if not found to be files.
```
> cp --verbose 'a[bc]d' dest
copied /home/bobhy/src/rust/work/r4/a[bc]d to /home/bobhy/src/rust/work/r4/dest/a[bc]d
> cp --verbose '[a][bc]d' dest
copied /home/bobhy/src/rust/work/r4/abd to /home/bobhy/src/rust/work/r4/dest/abd
copied /home/bobhy/src/rust/work/r4/acd to /home/bobhy/src/rust/work/r4/dest/acd
```
After_2: file with glob metachars but invalid pattern just works.
(though Windows does not allow file name to contain `*`.).
```
> cp --verbose 'a[b' dest
copied /home/bobhy/src/rust/work/r4/a[b to /home/bobhy/src/rust/work/r4/dest/a[b
```
So, with this fix, a file shadows a glob pattern with the same spelling.
If you have such a file and really want to use the glob pattern, you
will have to glob quote some of the characters in the pattern. I think
that's less confusing to the user: if ls shows a file with a weird name,
s/he'll still be able to copy, rename or delete it.
# User-Facing Changes
Could break some existing scripts. If user happened to have a file with
a globbish name but was using a glob pattern with the same spelling, the
new version will process the file and not expand the glob.

This PR is just a quick change to add `coreutils` to the `cp` command. I

# Description
This PR adds a new command called `debug info`. I'm not sure if the name
is right but we can rename it if needed. The purpose of this command is
to show a user how much memory nushell is using. This is what the output
looks like.
I feel like the further we go with nushell, the more we'll need to
easily monitor the memory usage. With this command, we should easily be
able to do that with scripts or just running the command.
```nushell

This PR renames nushell's `cp` command to `cp-old` to make room for
