# Description
Refactors the `flatten` command to remove a bunch of cloning. This was
down by passing ownership of the `Value` to `flat_value`, removing the
lifetime on `TableInside`, and using `Vec<Record>` in `FlattenedRows`
instead of a pair of `Vec` of columns and values.
For the quick benchmark below, it seems to be twice as fast now:
```nushell
let data = ls crates | where type == dir | each { ls $'($in.name)/**/*' }
timeit { for x in 0..1000 { $data | flatten } }
```
This took 550ms on v0.86.0 and only 230ms on this PR.
But considering that
```nushell
timeit { for x in 0..1000 { $data } }
```
takes 200ms on both versions, then the difference for `flatten` itself
is really 250ms vs 30ms -- 8x faster.
Provides support for reading Polars structs. This allows opening of
supported files (jsonl, parquet, etc) that contain rows with structured
data.
The following attached json lines
file([receipts.jsonl.gz](https://github.com/nushell/nushell/files/13311476/receipts.jsonl.gz))
contains a customer column with structured data. This json lines file
can now be loaded via `dfr open` and will render as follows:
<img width="525" alt="Screenshot 2023-11-09 at 10 09 18"
src="https://github.com/nushell/nushell/assets/56345/4b26ccdc-c230-43ae-a8d5-8af88a1b72de">
This also addresses some cleanup of date handling and utilizing
timezones where provided.
This pull request only addresses reading data from polars structs. I
will address converting nushell data to polars structs in a future
request as this change is large enough as it is.

# Description
Generally elide a bunch of unnecessary clones. Both globally stopping to
clone the whole input data in a bunch of places where we need to read it
but also some minor places where we currently cloned.
As part of that, we can make the overwriting with `keep-all` and
`keep-last` inplace so the items don't need to be removed and repushed
to the record.
# Benchmarking
```nu
timeit { scope commands | transpose -r }
```
Before ~24 ms now just ~5 ms
# User-Facing Changes
This can change the order of apperance in the transposed record with
`--keep-last`/`--keep-all`. Now the
order is determined by the first appearance and not by the last
appearance in the ingoing columns.
This mirrors the behavior when not passed `keep-all` or `keep-last`.
# Tests + Formatting
Sadly the `transpose` command is so far undertested for more complex
operations.
# Description
This PR refactors `drop columns` and fixes issues #10902 and #6846.
Tables with "holes" are now handled consistently, although still
somewhat awkwardly. That is, the columns in the first row are used to
determine which columns to drop, meaning that the columns displayed all
the way to the right by `table` may not be the columns actually being
dropped. For example, `[{a: 1}, {b: 2}] | drop column` will drop column
`a` instead of `b`. Before, this would give a list of empty records.
# User-Facing Changes
`drop columns` can now take records as input.
# Description
Compatible with `Vec::truncate` and `indexmap::IndexMap::truncate`
Found useful in #10903 for `drop column`
# Tests + Formatting
Doctest with the relevant edge-cases
# Description
Add an extension trait `IgnoreCaseExt` to nu_utils which adds some case
insensitivity helpers, and use them throughout nu to improve the
handling of case insensitivity. Proper case folding is done via unicase,
which is already a dependency via mime_guess from nu-command.
In actuality a lot of code still does `to_lowercase`, because unicase
only provides immediate comparison and doesn't expose a `to_folded_case`
yet. And since we do a lot of `contains`/`starts_with`/`ends_with`, it's
not sufficient to just have `eq_ignore_case`. But if we get access in
the future, this makes us ready to use it with a change in one place.
Plus, it's clearer what the purpose is at the call site to call
`to_folded_case` instead of `to_lowercase` if it's exclusively for the
purpose of case insensitive comparison, even if it just does
`to_lowercase` still.
# User-Facing Changes
- Some commands that were supposed to be case insensitive remained only
insensitive to ASCII case (a-z), and now are case insensitive w.r.t.
non-ASCII characters as well.

# Description
Replaces the only usage of `Value::follow_cell_path_not_from_user_input`
with some `Record::get`s.
# User-Facing Changes
Breaking change for `nu-protocol`, since
`Value::follow_cell_path_not_from_user_input` was deleted.
Nushell now reports errors for when environment conversions are not
closures.
# Description
This is pretty complementary/orthogonal to @IanManske 's changes to
`Value` cellpath accessors in:
- #10925
- to a lesser extent #10926
## Steps
- Use `R.remove` in `Value.remove_data_at_cell_path`
- Pretty sound after #10875 (tests mentioned in commit message have been
removed by that)
- Update `did_you_mean` helper to use iterator
- Change `Value::columns` to return iterator
- This is not a place of honor
- Use `Record::get` in `Value::get_data_by_key`
# User-Facing Changes
None intentional, potential edge cases on duplicated columns could
change (considered undefined behavior)
# Tests + Formatting
(-)
Matches the general behavior of `Vec::drain` or
`indexmap::IndexMap::drain`:
- Drop the remaining elements (implementing the unstable `keep_rest()`
would not be compatible with something like `indexmap`)
- No `AsRef<[T]>` or `Drain::as_slice()` behavior as this would make
layout assumptions.
- `Drain: DoubleEndedIterator`

# Description
Based of the work and discussion in #10844, this PR adds the `exec`
command for Windows. This is done by simply spawning a
`std::process::Command` and then immediately exiting via
`std::process::exit` once the child process is finished. The child
process's exit code is passed to `exit`.
# User-Facing Changes
The `exec` command is now available on Windows, and there should be no
change in behaviour for Unix systems.
# Description
Where appropriate, this PR replaces instances of
`Value::get_data_by_key` and `Value::follow_cell_path` with
`Record::get`. This avoids some unnecessary clones and simplifies the
code in some places.
Adds a special error, which is triggered by `alias foo=bar` style
commands. It adds a help string which recommends adding spaces.

# Description
Our config exists both as a `Config` struct for internal consumption and
as a `Value`. The latter is exposed through `$env.config` and can be
both set and read.
Thus we have a complex bug-prone mechanism, that reads a `Value` and
then tries to plug anything where the value is unrepresentable in
`Config` with the correct state from `Config`.
The parsing involves therefore mutation of the `Value` in a nested
`Record` structure. Previously this was wholy done manually, with
indices.
To enable deletion for example, things had to be iterated over from the
back. Also things were indexed in a bunch of places. This was hard to
read and an invitation for bugs.
With #10876 we can now use `Record::retain_mut` to traverse the records,
modify anything that needs fixing, and drop invalid fields.
# Parts:
- Error messages now consistently use the correct spans pointing to the
problematic value and the paths displayed in some messages are also
aligned with the keys used for lookup.
- Reconstruction of values has been fixed for:
- `table.padding`
- `buffer_editor`
- `hooks.command_not_found`
- `datetime_format` (partial solution)
- Fix validation of `table.padding` input so value is not set (and
underflows `usize` causing `table` to run forever with negative values)
- New proper types for settings. Fully validated enums instead of
strings:
- `config.edit_mode` -> `EditMode`
- Don't fall back to vi-mode on invalid string
- `config.table.mode` -> `TableMode`
- there is still a fall back to `rounded` if given an invalid
`TableMode` as argument to the `nu` binary
- `config.completions.algorithm` -> `CompletionAlgorithm`
- `config.error_style` -> `ErrorStyle`
- don't implicitly fall back to `fancy` when given an invalid value.
- This should also shrink the size of `Config` as instead of 4x24 bytes
those fields now need only 4x1 bytes in `Config`
- Completely removed macros relying on the scope of `Value::into_config`
so we can break it up into smaller parts in the future.
- Factored everything into smaller files with the types and helpers for
particular topics.
- `NuCursorShape` now explicitly expresses the `Inherit` setting.
conversion to option only happens at the interface to `reedline`
# Description
Since #10841 the goal is to remove the implementation details of
`Record` outside of core operations.
To this end use Record iterators and map-like accessors in a bunch of
places. In this PR I try to collect the boring cases where I don't
expect any dramatic performance impacts or don't have doubts about the
correctness afterwards
- Use checked record construction in `nu_plugin_example`
- Use `Record::into_iter` in `columns`
- Use `Record` iterators in `headers` cmd
- Use explicit record iterators in `split-by`
- Use `Record::into_iter` in variable completions
- Use `Record::values` iterator in `into sqlite`
- Use `Record::iter_mut` for-loop in `default`
- Change `nu_engine::nonexistent_column` to use iterator
- Use `Record::columns` iter in `nu-cmd-base`
- Use `Record::get_index` in `nu-command/network/http`
- Use `Record.insert()` in `merge`
- Refactor `move` to use encapsulated record API
- Use `Record.insert()` in `explore`
- Use proper `Record` API in `explore`
- Remove defensiveness around record in `explore`
- Use encapsulated record API in more `nu-command`s

# Description
Changes the `captures` field in `Closure` from a `HashMap` to a `Vec`
and makes `Stack::captures_to_stack` take an owned `Vec` instead of a
borrowed `HashMap`.
This eliminates the conversion to a `Vec` inside `captures_to_stack` and
makes it possible to avoid clones altogether when using an owned
`Closure` (which is the case for most commands). Additionally, using a
`Vec` reduces the size of `Value` by 8 bytes (down to 72).

# Description
Replaces the `Vec::remove` in `Record::retain_mut` with some swaps which
should eliminate the `O(n^2)` complexity due to repeated shifting of
elements.
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

# Description
Consequences of #10841
This does not yet make the assumption that columns are always
duplicated. Follow the existing logic here
- Use saner record API in `nu-engine/src/eval.rs`
- Use checked record construction in `nu-engine/src/scope.rs`
- Use `values` iterator in `nu-engine/src/scope.rs`
- Use `columns` iterator in `nu_engine::get_columns()`
- Start using record API in `value/mod.rs`
- Use `.insert` in `eval_const.rs` Record code
- Record API for `eval_const.rs` table code

# 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

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.

intermediate directory. In such a case we:
- only suggest directory names
- don't append the slash since it is already present
- only complete the path till the component the cursor is on

# Description
Reuses the existing `Closure` type in `Value::Closure`. This will help
with the span refactoring for `Value`. Additionally, this allows us to
more easily box or unbox the `Closure` case should we chose to do so in
the future.
# User-Facing Changes
Breaking API change for `nu_protocol`.
# Description
These macros simply took a `Span` and a shared reference to `Config` and
returned a Value, for better readability and reasoning about their
behavior convert them to simple function as they don't do anything
relevant with their macro powers.

# Description
While we have now a few ways to add items or iterate over the
collection, we don't have a way to cleanly remove items from `Record`.
This PR fixes that:
- Add `Record.remove()` to remove by key
- makes the assumption that keys are unique, so can not be used
universally, yet (see #10875 for an important example)
- Add naive `Record.retain()` for inplace removal
- This follows the two separate `retain`/`retain_mut` in the Rust std
library types, compared to the value-mutating `retain` in `indexmap`
- Add `Record.retain_mut()` for one-pass pruning
Continuation of #10841
# User-Facing Changes
None yet.

Doctests for the `retain`ing fun

This PR restores and old functionality that must of been broken with the

# 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
> Our `Record` looks like a map, quacks like a map, so let's treat it
with the API for a map
Implement common methods found on e.g. `std::collections::HashMap` or
the insertion-ordered [indexmap](https://docs.rs/indexmap).
This allows contributors to not have to worry about how to get to the
relevant items and not mess up the assumptions of a Nushell record.
## Record assumptions
- `cols` and `vals` are of equal length
- for all practical purposes, keys/columns should be unique
## End goal
The end goal of the upcoming series of PR's is to allow us to make
`cols` and `vals` private.
Then it would be possible to exchange the backing datastructure to best
fit the expected workload.
This could be statically (by finding the best balance) or dynamically by
using an `enum` of potential representations.
## Parts
- Add validating explicit part constructor
`Record::from_raw_cols_vals()`
- Add `Record.columns()` iterator
- Add `Record.values()` iterator
- Add consuming `Record.into_values()` iterator
- Add `Record.contains()` helper
- Add `Record.insert()` that respects existing keys
- Add key-based `.get()`/`.get_mut()` to `Record`
- Add `Record.get_index()` for index-based access
- Implement `Extend` for `Record` naively
- Use checked constructor in `record!` macro
- Add `Record.index_of()` to get index by key
# User-Facing Changes
None directly
# Developer facing changes
You don't have to roll your own record handling and can use a familiar
API
# Tests + Formatting
No explicit unit tests yet. Wouldn't be too tricky to validate core
properties directly.
Will be exercised by the following PRs using the new
methods/traits/iterators.
# 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
ὈΔΥΣΣΕΎΣ

- downcase now works

# Description
looking at the [Wax documentation about
`wax::Walk.not`](https://docs.rs/wax/latest/wax/struct.Walk.html#examples),
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.
# After Submitting
prepare the removal PR and mention in release notes.

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
- 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
❯ echo aaa o> | ignore

# Description
Support pattern matching against the `null` literal. Fixes#10799
### Before
```nushell

failure
```
### After
```nushell
> match null { null => "success", _ => "failure" }
success
```
# 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}
```
# User-Facing Changes
Using the `--flexible` flag with `from csv` and `from tsv` will not
result in corrupted record state.

- Add `detailed` flag for `describe`
- Improve detailed describe and better format when running examples.
# Rationale
For now, neither `describe` nor any of the `debug` commands provide an
easy and structured way of inspecting the data's type and more. This
flag provides a structured way of getting such information. Allows also
to avoid the rather hacky solution
```nu
$in | describe | str replace --regex '<.*' ''
```
# User-facing changes
Adds a new flag to ``describe`.
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.

# User-Facing Changes
- `registry query` used to accidentally mangle values that contain a
literal `\\`, such as UNC paths. It no longer does so.

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
error index to large
# ----
> let arg = [0 5 a c]
> [[a b];[1 2] [3 4] [5 6]] | reject $a -i | to nuon
[[a, b]; [1, 2], [3, 4], [5, 6]]
```
When looking into `lite_parse` function, I found that it contains some
duplicate code, and they can be expressed as an action called
`push_command_to(pipeline)`.
And I believe it will make our life easier to support something like
`o>> a.txt`, `e>> a.txt`.
In the final match of `lex_item`, we'll return `Err(ParseError)` in rare
case, normally we'll return None.
So I think making error part mutable can reduce some code, and it's
better if we want to add more lex items.

(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.
```

```
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]

```
After: Args to cp, mv, etc. are tried first as literal files, and only
as globs if not found to be files.
```

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 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
❯ debug info | table -e

Fixes#10696
# Description
As reported, you could mess up the ring of remembered directories in
`std dirs` (a.k.a the `shells` commands) with a sequence like this:
```
~/test> mkdir b c
~/test> pushd b
~/test/b> cd ../c
~/test/c> goto 0
~/test> goto 1
## expect to end up in ~/test/c
## observe you're in ~/test/b
~/test/b>
```
Problem was `dirs goto` was not updating the remembered directories
before leaving the current slot for some other. This matters if the user
did a manual `cd` (which cannot update the remembered directories ring)

Re-fixes #3674, if that is seen as desirable to do.
# Description
This PR changes the implementation of the `--features=extra` string
casing commands from Inflector to `heck`, as in PR #4081. This PR landed
a long time ago, but somewhere along the way (i can't find it) the
implementation ended up being switched back to Inflector.
# User-Facing Changes
Inflector and `heck` implement casing differently, so all of the
commands have different behavior around edge cases (consecutive
capitals, interspersed numbers and letters, etc)
### Before
```nu
G:/Dev/nu-itself/nushell> [UserID ABCdefGHI foo123bar] | str camel-case
╭───┬───────────╮
│ 0 │ userID │
│ 1 │ abcdefGHI │
│ 2 │ foo123Bar │
╰───┴───────────╯
G:/Dev/nu-itself/nushell> [UserID ABCdefGHI foo123bar] | str snake-case
╭───┬─────────────╮
│ 0 │ user_id │
│ 1 │ ab_cdef_ghi │
│ 2 │ foo_12_3bar │
╰───┴─────────────╯
```
### After
```nu
G:/Dev/nu-itself/nushell> [UserID ABCdefGHI foo123bar] | str camel-case
╭───┬───────────╮
│ 0 │ userId │
│ 1 │ abCdefGhi │

G:/Dev/nu-itself/nushell> [UserID ABCdefGHI foo123bar] | str snake-case
╭───┬─────────────╮

╰───┴─────────────╯
```
# Tests + Formatting
The existing string casing tests pass... because none of them relied on
any of these edge cases
# Description
Open question:
Undocumented behavior for the new argument `ambiguous` to the
`as_datetime`
methods. I cheated by passing a default (assuming empty string).
This appears like an API primarily serving the python impl:
https://pola-rs.github.io/polars/py-polars/html/reference/expressions/api/polars.Expr.str.to_datetime.html#polars-expr-str-to-datetime
# User-Facing Changes
Only dependent on breaking changes to the behavior of polars.
# Tests + Formatting
No observed changes to tests
Manually checked `dfr as-datetime`, doesn't seem to panic.
# Description
Those commands either only return `Type::Float` or `Type::Int`

# User-Facing Changes

# Description

of `SyntaxShape::Number`.

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

`cp-old` entirely.

# Description
The issue #10318 is resolved by introducing helper methods within the
existing `get_documentation` function in the nu-engine crate. Initially,
I considered using nu-color-config crate to convert HEX config color to
ANSI color and employing the following method
[https://github.com/nushell/nushell/blob/main/crates/nu-color-config/src/color_config.rs#L9C1-L20C2](https://github.com/nushell/nushell/blob/main/crates/nu-color-config/src/color_config.rs#L9C1-L20C2).
However, this approach was deemed impractical due to circular
dependencies. Consequently, in a manner akin to how we invoke the
`table` command from the nu-command crate in `get_documentation`
function to create a themed-colored table, we invoke the `ansi` command
from nu-command to obtain the ANSI theme color code.
# User-Facing Changes
Visual Changes Only: the help command now uses configured theme, else it
falls back on default hard coded values.

This pr fix clippy warnings in latest clippy version(1.72.0):
Unfortunally it's not easy to handle for [try
fold](https://rust-lang.github.io/rust-clippy/master/index.html#/manual_try_fold)
warning in `start command`
Refer to known issue:
> This lint doesn’t take into account whether a function does something
on the failure case, i.e., whether short-circuiting will affect
behavior. Refactoring to try_fold is not desirable in those cases.
That's the case for our code, which does something on the failure case.
So this pr is making a little refactor on `try_commands`.
# Description
Relax typechecking of key-less `table`/`record`
Assume that they are acceptable for more narrowly specified
`table<...>`/`record<...>` where `...` specifies keys and potentially
types for those keys/columns.
This ensures that you can use commands that specify general return
values statically with more specific input-/args-type requirements.
Reduces the power of the type-check a bit but unlocks you to actually
use the specific annotations in more places.
Incompatibilities will only be raised if an output type declares
specific columns/keys.
Closes#9702
Supersedes #10594 as a simpler solution requiring no extra distinction.
h/t @1kinoti, @NotLebedev
# User-Facing Changes
Now legal at type-check time
```nu
def foo []: nothing -> table { [] }
def foo []: nothing -> table<> { ls }
def bar []: table<a:int,b:string> -> nothing {}
foo | bar
```
# Tests + Formatting
- 1 explicit test with specified relaxed return type passed to concrete
expected input type

inference in the function body
# Description
Fixes https://github.com/nushell/nushell/issues/10605 (again).

# Description
Closes#10537. Basically error message was unhelpful, and this temporary
measure adds back the nice previous nushell error message. Ideally, we
would like to add a more permanent solution mentioned in the issue
[comments](https://github.com/nushell/nushell/issues/10537#issuecomment-1743686122),
but since we want to have `ucp` as `cp` on new release, this is hackier
but way simpler so this fix should do it.
Only downside is that now behavior differs from `uutils` in the sense
that:
```
uutils:
> cp a foo/ bar
ls bar
# foo/a
nushell:
>ucp a foo/ bar
# directory error (not copied) ....
```
So, since its non fatal error, uutils copies a, but nushell errors out
with nothing copied. If we go to option 3 mentioned above, then we can
decide what we want to do, and perhaps continue on a non fatal error.

This PR removes the underline from the log format. It's been messing
things up for me since there is no ansi reset in the log format and
therefore everything after it is underlined.

Reverts nushell/nushell#10596
Using the long option in examples is going to be confusing as it makes
the reader think the long option is required. It also isn't idiomatic
Nushell.
The examples should be copy-paste-able as idiomatic Nushell, so as such
we shouldn't expand them to the long flag name.

# Description
"can't follow stream paths" errors have always been a bit scary and
obnoxious because they give no information about what happens...
in this PR i try to slightly improve the error message by telling if the
stream was empty or not and give span information when available.

When referring to the type use `int` consistently. Only when referring
to the concept of integer numbers use `integer`.
- Fix `random integer` to `random int` tests
- Forgot in #10520
- Use int instead of integer in error messages
- Use int type name in bits commands
- Fix messages in `for` examples
- Use int typename in `into` commands
- Use int typename in rest of commands
- Report errors in `nu-protocol` with int typename
Work for #10332
# User-Facing Changes
User errorrs should now use `int` so you can easily find the necessary
commands or type annotations.

Only two tests found that needed updating
code cleanup of *eval.rs*
I was reviewing the engine code and noticed this...
The *eval_element_with_input* method in eval.rs does not need to be
public at the moment
because no one is calling it...
@jntrnr is making this method not public going to block someone in the
future who might need it ?
Right now its not being used so I decided to tighten up the API a bit...
# Description
This removes the old style "cd with abbreviations" that would attempt to
guess what directory you wanted to `cd` to. This would sometimes have
false positives, so we left it off by default in the config.
In the current main, we have much-improved path completions
(https://github.com/nushell/nushell/pull/10543) so you can now do `cd
a/b<tab>` and get a much better experience (because you can see the
directory you're about to cd to). This removes the need for the previous
abbreviation system.
# User-Facing Changes
This does remove the old abbreviation system. It will likely mean that
old config files that have settings for abbreviations will now get
errors.
update: here's an example of the error you'll see:

- #10283
# Description
even though it appears defining `to foo` does not allow to do `save
x.foo` for free (see https://github.com/nushell/nushell/issues/10429),
because #10283 did add `from ndjson` and `from jsonl` to the standard
library, i thought adding their `to ...` counterpart would make sense
😋
# User-Facing Changes
users can now convert structured data back to NDJSON and JSONL 👌
# Tests + Formatting
this PR adds the exact same tests as for the `from ...` commands
- structured data is in `result` and the string is now the expected
- the two invalid `from ...` tests cannot be reproduced for `to ...`

# After Submitting
Remove code for 2 no-longer-used configuration options in `explore`:
`explore.config.cursor_color` and `explore.config.border_color`.
Think I made these unnecessary in
https://github.com/nushell/nushell/pull/10533 and
https://github.com/nushell/nushell/pull/10270 but missed this code, my
bad. The `explore` config code is a little hard to follow because it
does so many key lookups in hashmaps.
# Description
Retrieving tests and their annotation no longer uses nu --ide-ast
spawned in a subprocess which should reduce test runner startup time.
# User-Facing Changes
# Tests + Formatting
# After Submitting
This PR removes the `line_head_top`, `line_head_bottom`, `line_shift`,
and `line_index` configuration options from `explore`. These were
previously used to control whether the horizontal+vertical lines in this
`ls | explore -i` screenshot would be displayed:
Now, all lines are displayed (same as the previous default config
values) and this is no longer configurable.
## Context
I'm continuing to chip away at `explore` when I have time. I have a
long-term goal to make `explore` simpler for users+developers. For now
I'm mostly making small incremental changes where I find underused
functionality+configuration and remove it; hopefully eventually this
will make it easier to make larger changes.
I found these specific config options a little hard to understand when
reading `explore` code, and when reading `config.nu` as a user their
behaviour+naming is not obvious. I also think that in the long term,
`explore` styling should inherit most styling from `table` instead of
having its own styling system.
The value rendering code in explore is _very_ flexible; values can be
rendered with orientation `Top`, `Left`, `Bottom`, or `Right`. The
default is `Top` for tables (header at the top) and `Left` for records
(header on the left).
This PR removes `Bottom` and `Right`; they are largely untested,
probably used by nobody, and they complicate the rendering code.
## Testing Performed
I've manually confirmed that tables and records still render the same
ass before, and the `t`/transpose command still works.

> [!NOTE]
> This PR description originally used examples where the `generator`
closure returned a list. It has since been updated to use records
instead.
The `unfold` command allows users to dynamically generate streams of
data. The stream is generated by repeatedly invoking a `generator`
closure. The `generator` closure accepts a single argument and returns a
record containing two optional keys: 'out' and 'next'. Each invocation,
the 'out' value, if present, is added to the stream. If a 'next' key is
present, it is used as the next argument to the closure, otherwise
generation stops.
The name "unfold" is borrowed from other functional-programming
languages. Whereas `fold` (or `reduce`) takes a stream of values and
outputs a single value, `unfold` takes a single value and outputs a
stream of values.
### Examples
A common example of using `unfold` is to generate a fibbonacci sequence.
See
[here](6ffdac103c/src/sources.rs (L65))
for an example of this in rust's `itertools`.
```nushell
> unfold [0, 1] {|fib| {out: $fib.0, next: [$fib.1, ($fib.0 + $fib.1)]} } | first 10
───┬────
0 │ 0
1 │ 1
2 │ 1
3 │ 2
4 │ 3
5 │ 5
6 │ 8
7 │ 13
8 │ 21
9 │ 34
───┴────
```
This command is particularly useful when consuming paginated APIs, like
Github's. Previously, nushell users might use a loop and buffer
responses into a list, before returning all responses at once. However,
this behavior is not desirable if the result result is very large. Using
`unfold` avoids buffering and allows subsequent pipeline stages to use
the data concurrently, as it's being fetched.
#### Before
```nushell
mut pages = []
for page in 1.. {
let resp = http get (
{
scheme: https,
host: "api.github.com",
path: "/repos/nushell/nushell/issues",
params: {
page: $page,
per_page: $PAGE_SIZE
}
} | url join)
$pages = ($pages | append $resp)
if ($resp | length) < $PAGE_SIZE {
break
}
}
$pages
```
#### After
```nu
unfold 1 {|page|
let resp = http get (
{
scheme: https,
host: "api.github.com",
path: "/repos/nushell/nushell/issues",
params: {
page: $page,
per_page: $PAGE_SIZE
}
} | url join)
if ($resp | length) < $PAGE_SIZE {
{out: $resp}
} else {
{out: $resp, next: ($page + 1)}
}
}
```

Closes#10441
Uses `String::to_lowercase()` when the file's extension `ext` is parsed
to allow `from_decl(format!("from {ext}"))` to return the desired output
regardless of extension case.
It doesn't work with sqlite files since those are handled earlier in the
parsing but I think is good- since there's no standard file extension
used by sqlite so a user will likely want case sensitivity in that case.
This also has the (possibly undesired) effect of making `open`
completely case insensitive, e.g. `open foo.JSON` will work on a file
named `foo.json` and vice versa. This is good on Windows as it treats
`foo.json` and `foo.JSON` as the same file, but may not be the desired
behaviour on Unix.
If this behaviour is undesired I assume it would be fixed with a
`#[cfg(not(unix))]` attribute on the `to_lowercase()` operation but that
produces slightly "uglier" code that I didn't wish to submit unless
necessary.
old behaviour:
new behaviour:
# User-Facing Changes
`open` will now present a table when `open`-ing files with captitalized
extensions rather than the file's raw data
# Tests + Formatting
new test: `parses_file_with_uppercase_extension` which tests the desired
behaviour

This pr closes#10521.
# Description
The default prompt by nushell will replace `$nu.home-path` with `~`.
E.g. for a user named `user`, `/home/user` would become `~`. This also
works with sub paths, e.g. `/home/user/docs` would become `~/docs`.
The issue is that this replacement was a tad overzealous. A path like
`/home/user-with-suffix` would become `~-with-suffix`. This PR fixes the
issue by updating the home path detection logic.
# User-Facing Changes
The bugged behavior no longer occurs.
# Tests + Formatting
* `cargo` checks were not performed as this does not touch rust.
* The updated logic was tested against
[elvish](https://github.com/elves/elvish)'s path replacement logic, for
~10,000 randomly selected folders on a linux server. All paths were
processed the same.
# Description
This merges @horasal 's changes from #10246 and #10269Closes#10205Closes#8714
Fixes the bug that editor paths with spaces are unusable
Closes#10210Closes#10269
# User-Facing Changes
You can now either pass a string with the name of the executable or a
list with the executable and any flags to
`$env.config.buffer_editor`/`$env.EDITOR`/`$env.VISUAL`
Both the external buffer editor of reedline (by default bound to
`Ctrl-o`) and the commands `config nu` and `config env` will respect
those variables in the following order:
1. `$env.config.buffer_editor`
2. `$env.EDITOR`
3. `$env.VISUAL`
Example:
```
$env.EDITOR = "nvim" # The system-wide EDITOR is neovim
$env.config.buffer_editor = ["vim" "-p2"] # Force vim to open two tabs (not particularly useful)
$env.config.buffer_editor = null # Unset `buffer_editor` -> Uses `$env.EDITOR` ergo nvim
```

# Description
Support keyboard enhancement protocol as implemented by Kitty console,
hence Kitty protocol.
This PR enables Nushell to use keybinding that is not available before,
such as Ctrl+i (that alias to Tab) or Ctrl+e (that alias to Esc, likely
I mistaken). After this PR merged and you set `use_kitty_protocol`
enabled, if your console app support Kitty protocol (WezTerm, Kitty,
etc.) you will be able to set more fine-grained keybinding.
For Colemak users, this feature is a blessing, because some Ctrl+[hjkl]
that previously unmap-able to Ctlr+[hnei] now it is.
# User-Facing Changes
This adds `use_kitty_protocol` config which defaults to false. When set
to `true`, it enables kitty protocol on the line editor when supported,
or else it warns.

Fixes#10503
Also improves link to metacharacter help;
# Description
`glob` code was using pattern as provided by user. If that had leading
`..\`, `wax::Glob` is documented to treat them as literal chars to be
matched.
Fix is to use `wax::Glob.partition()` to split such invariant prefixes
off the pattern and tack them onto the working directory computed
separately.

More incremental `explore` improvements!
This PR removes the `show_cursor` config from the `explore` command, in
favour of always using the background colour to highlight the selected
cell. I believe this is a better default and I'd like to remove the
`show_cursor` functionality entirely as part of the effort to simplify
`explore`.
The style for selected cells is still configurable. I went with light
blue for the default background colour, it looks OK to me.

# Description
Those `SyntaxShape`s can not coerce to `Value`s or `Type`s that can be
used by the user in an argument or input-output-type position.
Supporting them doesn't make sense.

positions

# Description
Fixes#2047 but for the `doas` command the same way as in #8094
# User-Facing Changes
No breaking changes. If people not using `doas`, no difference at all.
# Tests
I have not added any tests since its using same logic as for "sudo". I
guess if something would go wrong in this part, sudo tests will cover
it?
# Additional context
As a nushell user I could not find a way to implement custom completion
for a "sudo like command". Since I can see `sudo` being hardcoded in
sources, this is what I propose.
~~Also I have almost zero knowledge of rust and this is definitely not
the clean way yet~~

# Description
We don't use this shape during parsing and never reference it in command
signatures. Thus it should be removed.
# User-Facing Changes
None functional.
Plugin authors that used it would never be provided with data that
specifically matched `SyntaxShape::Variable`
Builds using it will now fail.

thanks to @jntrnr and their super useful tips on this PR, i learned
about the parser + evaluation, so 🙏
# Description
because we already have `null` as the value of the type `nothing` and as
a followup to the two other attempts of mine, i propose to remove the
redundant `$nothing` built-in variable 😋
this PR is the first step, deprecating `$nothing`.
a followup PR will remove it altogether and wait for 0.87 👍⚙️ **details**: a new `NOTHING_VARIABLE_ID = 3` has been added,
parsing `$nothing` will create it, finally a `Value::Nothing` will be
produced and a warning will be reported.
this PR already fixes the `toolkit.nu` module so that it does not throw
a bunch of warnings each time 👌
# User-Facing Changes
`$nothing` is now deprecated and will be removed in 0.87
```nushell
> $nothing
Error: × Deprecated variable
╭─[entry #1:1:1]

· ────┬───
· ╰── `$nothing` is deprecated and will be removed in 0.87.

help: Use `null` instead
```
# Tests + Formatting
tests have been updated, especially
- `nothing_fails_string`
- `nothing_fails_int`
which use a variable called `nil` now to make sure `nothing` does not
support cell paths 👍
# After Submitting
classic deprecation mention 👍
