# Description
This does a lookup in the cache of parsed files to see if a span can be
found for a file that was previously loaded with the same contents, then
uses that span to find the parsed block for that file. The end result
should, in theory, be identical but doesn't require any reparsing or
creating new blocks/new definitions that aren't needed.
This drops the sg.nu benchmark from:

# Description
We were seeing duplicate entries for the std lib files, and this PR
addresses that. Each file should now only be added once.
Note: they are still parsed twice because it's hard to recover the
module from the output of `parse` but a bit of clever hacking in a
future PR might be able to do that.

# Description
Verified on discord with maintainer
Change adds regex separators in split rows/column/list. The primary
motivating reason was to make it easier to split on separators with
unbounded whitespace without requiring a lot of trim jiggery. But,
secondary motivation is the same as the set of all motivations for
adding split regex features to most languages.
# User-Facing Changes
Adds -r option to split rows/column/list.

# Description
The two tests `to_nuon_from_nuon` and `to_nuon_from_nuon_string` were
taking multiple seconds and have since been superseded by more explicit

returned explicit problems. One failure only popped up after months, as
a sampled failure (https://github.com/nushell/nushell/pull/7564).

# Description
Currently, all four of these commands return a (rather-confusing)
spanless error when passed an empty list:
```
> [] | sort
Error:
× no values to work with
help: no values to work with
```
This PR changes these commands to always output `[]` if the input is
`[]`.
```
> [] | sort
╭────────────╮
│ empty list │
╰────────────╯
> [] | uniq-by foo
╭────────────╮
│ empty list │
╰────────────╯
```
I'm not sure what the original logic was here, but in the case of `sort`
and `uniq`, I think the current behavior is straightforwardly wrong.
`sort-by` and `uniq-by` are a bit more complicated, since they currently
try to perform some validation that the specified column name is present
in the input (see #8667 for problems with this validation, where a
possible outcome is removing the validation entirely). When passed `[]`,
it's not possible to do any validation because there are no records.
This opens up the possibility for situations like the following:
```
> [[foo]; [5] [6]] | where foo < 3 | sort-by bar
╭────────────╮
│ empty list │
╰────────────╯
```
I think there's a strong argument that `[]` is the best output for these
commands as well, since it makes pipelines like `$table | filter
$condition | sort-by $column` more predictable. Currently, this pipeline
will throw an error if `filter` evaluates to `[]`, but work fine
otherwise. This makes it difficult to write reliable code, especially
since users are not likely to encounter the `filter -> []` case in
testing (issue #5957). The only workaround is to insert manual checks
for an empty result. IMO, this is significantly worse than the "you can
typo a column name without getting an error" problem shown above.
Other commands that take column arguments (`get`, `select`, `rename`,
etc) already have `[] -> []`, so there's existing precedent for this
behavior.
The core question here is "what columns does `[]` have"? The current
behavior of `sort-by` is "no columns", while the current behavior of
`select` is "all possible columns". Both answers lead to accepting some
likely-buggy code without throwing on error, but in order to do better
here we would need something like `Value::Table` that tracks columns on
empty tables.
If other people disagree with this logic, I'm happy to split out the
`sort-by` and `uniq-by` changes into another PR.
# User-Facing Changes
`sort`, `uniq`, `sort-by`, and `uniq-by` now return `[]` instead of
throwing an error when input is `[]`.

The existing behavior was not documented, and the new behavior is what
you would expect by default, so I don't think we need to update
documentation.

This PR fixes a bug introduced in
https://github.com/nushell/nushell/pull/8571.
We were accidentally converting a `Result<Value, ShellError>` to JSON
instead of converting a `Value`. The upshot was that we were sending
JSON like `{"Ok":{"foo":"bar"}}` instead of `{"foo":"bar"}`.
This was an easy bug to miss, because `ureq::send_json()` accepts any
`impl serde::Serialize`. I've added a test to prevent regression.
# Description
This removes all the old style of quasi-ranges before we had full range
support from `str substring`. Functionality should otherwise work, but
only with the official range syntax.

This PR fixes `select` when given an empty list; it used to return
`null` when given an empty list. I also cleaned up other `select` tests
while I was in the area.
### Before:
```
> [] | select a | to nuon
null
```
### After:
```
> [] | select a | to nuon
[]
```
It looks like the previous behaviour was accidentally introduced by
[this PR](https://github.com/nushell/nushell/pull/7639).
# Description
Require that any value that looks like it might be a number (starts with
a digit, or a '-' + digit, or a '+' + digits, or a special form float
like `-inf`, `inf`, or `NaN`) must now be treated as a number-like
value. Number-like syntax can only parse into number-like values.
Number-like values include: durations, ints, floats, ranges, filesizes,
binary data, etc.

# Description
This removes autoprinting the final value of a loop, much in the same
spirit as not autoprinting values at the end of statements. As we fix
these corner cases, it becomes more consistent that to print to the
screen in a script, you use the `print` command.
This gives a noticeable performance improvement as a bonus.

Prior to this PR, the less/greater than operators (`<`, `>`, `<=`, `>=`)
would throw an error if either side was null. After this PR, these
operators return null if either side (or both) is null.
### Examples
```bash
1 < 3 # true
1 < null # null
null < 3 # null
null < null # null
```
### Motivation
JT [asked the C#
folks](https://discord.com/channels/601130461678272522/615329862395101194/1086137515053957140)
and this is apparently the approach they would choose for comparison
operators if they could start from scratch.
This PR makes `where` more convenient to use on jagged/missing data. For
example, we can now filter on columns that may not be present in every
row:
```
> [{foo: 123} {}] | where foo? > 10
╭───┬─────╮
│ # │ foo │
├───┼─────┤
│ 0 │ 123 │
╰───┴─────╯
```
this pr refines #8270 and closes#8109
# description
examples:
the original syntax is okay
```nu
def okay [nums: list] {} # the type of list will be list<any>
```
empty annotations are allowed in any variation
the last two may be caught by a future formatter,
but do not affect `nu` code currently
```nu
def okay [nums: list<>] {} # okay
def okay [nums: list< >] {} # weird but also okay
def okay [nums: list<
>] {} # also weird but okay
```
types are allowed (See [notes](#notes) below)
```nu
def okay [nums: list<int>] {} # `test [a b c]` will throw an error
def okay [nums: list< int > {} # any amount of space within the angle brackets is okay
def err [nums: list <int>] {} # this is not okay, `nums` and `<int>` will be parsed as
# two separate params,
```
nested annotations are allowed in many variations
```nu
def okay [items: list<list<int>>] {}
def okay [items: list<list>] {}
```
any unterminated annotation is caught
```nu
Error: nu::parser::unexpected_eof

# Description
**TL;DR**: this PR adds `--indent <int>`, `--tabs <int>` and `--raw` to
control a bit more the `string` output of `to nuon`, as done in `to
json` already, the goal being to promote the `NUON` format through easy
to read and formatted output `.nuon` files 😋
### outside of `crates/nu-command/src/formats/to/nuon.rs`
as the signature of `value_to_string` has changed, the single call to it
outside of its module definition has been changed to use default values
=> `value_to_string(&value, Span::unknown(), 0, &None)` in
`crates/nu-command/src/filters/uniq.rs`
### changes to `ToNuon` in `crates/nu-command/src/formats/to/nuon.rs`
- the signature now features `--raw`, `--indent <int>` and `--tabs
<int>`
- the structure of the `run` method is inspired from the one in `to
json`
- we get the values of the arguments
- we convert the input to a usable `Value`
- depending on whether the user raised `--raw`, `--indent` or `--tabs`,
we call the conversion to `string` with different values of the
indentation, starting at depth 0
- finally, we return `Ok` or a `ShellError::CantConvert` depending on
the conversion result
- some tool functions
- `get_true_indentation` gives the full indentation => `indent` repeated
`depth` times
- `get_true_separators` gives the line and field separators => a `("\n",
"")` when using some formatting or `("", " ")` when converting as pure
string on a single line
the meat of `nuon.rs` is now the `value_to_string` recursive function:
- takes the depth and the indent string
- adds correct newlines, space separators and indentation to the output
- calls itself with the same indent string but `depth + 1` to increase
the indentation by one level
- i used the `nl`, `idt`, `idt_po` (**i**n**d**en**t** **p**lus **o**ne)
and `idt_pt` (**i**n**d**en**t** **p**lus **t**wo) to make the
`format!`s easier to read
# User-Facing Changes
users can now
- control the amount and nature of NUON string output indentation with
- `--indent <number of " " per level>`
- `--tabs <number of "\t" per level>`
- use the previous behaviour of `to nuon` with the `--raw` option
- have new examples with `help to nuon`
> **Note**
> the priority order of the options is the following
> 1. `--raw`
> 2. `--tabs`
> 3. `--indent`
>
> the default is `--indent 2`
# Tests + Formatting
### new tests
- tests involving the string output of `to nuon`, i.e. tests not of the
form `... | to nuon | from nuon ...`, now use the `to nuon --raw`
command => this is the smallest change to have the tests pass, as the
new `to nuon --raw` is equivalent to the old `to nuon`
- in `crates/nu-command/src/formats/to/nuon.rs`, the previous example
has been replaced with three examples
- `[1 2 3] | to nuon` to show the default behaviour
- `[1 2 3] | to nuon --raw` to show the not-formatted output
- a more complex example with `{date: 2000-01-01, data: [1 [2 3] 4.56]}
| to nuon`
- the result values have been defined and the `examples` tests pass
### dev
- 🟢 `cargo fmt --all`
- 🟢 `cargo clippy --workspace -- -D warnings -D
clippy::unwrap_used -A clippy::needless_collect`
- 🟢 `cargo test --workspace` ~~passes but without
`to_nuon_errs_on_closure`~~ fixed in

# After Submitting
the `to nuon` page would have to be regenerated at some point due to the
new tests
# Description
This adds two different features to `open`:
* The ability to pass more than one file to `open`.
* Support for using globs in the filenames
`open` will create a list stream and stream the output if there is more
than one file opened
Examples:
```
open file1.csv file2.csv file3.csv
```
```
open *.nu | where $it =~ "echo"
```
# User-Facing Changes
Multi-file and glob support in `open`. Original `open` functionality
should continue as before.

# Description

# User-Facing Changes
when define a closure without pipe, nushell will raise error for now:
```
❯ let x = {ss ss}
Error: nu::parser::closure_missing_pipe
× Missing || inside closure
╭─[entry #2:1:1]
1 │ let x = {ss ss}
· ───┬───
· ╰── Parsing as a closure, but || is missing
╰────
help: Try add || to the beginning of closure
```
`any`, `each`, `all`, `where` command accepts closure, it forces user
input closure like `{||`, or parse error will returned.
```
❯ {major:2, minor:1, patch:4} | values | each { into string }
Error: nu::parser::closure_missing_pipe
× Missing || inside closure

· ───────┬───────
· ╰── Parsing as a closure, but || is missing
╰────
help: Try add || to the beginning of closure
```
`with-env`, `do`, `def`, `try` are special, they still remain the same,
although it says that it accepts a closure, but they don't need to be
written like `{||`, it's more likely a block but can capture variable
outside of scope:
```
❯ def test [input] { echo [0 1 2] | do { do { echo $input } } }; test aaa
aaa
```
Just realize that It's a big breaking change, we need to update config
and scripts...

# Description
Resolves issue #8370
Adds the following flags to commands `from csv` and `from tsv`:
- `--flexible`: allow the number of fields in records to be variable
- `-c --comment`: a comment character to ignore lines starting with it
- `-q --quote`: a quote character to ignore separators in strings,
defaults to '\"'
- `-e --escape`: an escape character for strings containing the quote
character
Internally, the `Value` struct has an additional helper function
`as_char` which converts it to a single `char`
# User-Facing Changes
The single quoted string `'\t'` can no longer be used as a parameter for
the flag `--separator '\t'` as it is interpreted as a two-character
string. One needs to use from now on the flag with a double quoted
string like so: `-s "\t"` which correctly interprets the string as a
single `char`.
# Description
This adds back support for parens around params, eg `def foo (x: int) {
... }`
# User-Facing Changes
returns to the original support before the recent parser refactor

https://github.com/nushell/nushell/pull/8379 removed the `-i` flag from
`get` and `select` because the new `?` functionality covers most of the
same use cases. However, https://github.com/nushell/nushell/issues/8480
made me realize that `-i` is still useful when dealing with cell paths
in variables.
This PR re-adds the `-i` flag to `get` and `select`. It works by just
marking every member in the cell path as optional, which will behave
_slightly_ differently than `-i` used to (previously it would suppress
any errors, even type errors) but IMO that's OK.
This reverts commit dec0a2517f.
It breaks programs like `fzf`

# Description
Fixes: #8402#8391
The cause of these issue if when we want to evaluate a expression with
`Value::Error`, nushell show error immediately. To fix the issue, we can
wrap the `Value::Error` into a `Value::Record`. So user can see the
message he want.
# User-Facing Changes
Before
```
❯ try { 1 / 0 } catch {|e| echo $"error is ($e)"}
Error: nu:🐚:division_by_zero
× Division by zero.
╭─[entry #2:1:1]
1 │ try { 1 / 0 } catch {|e| echo $"error is ($e)"}
· ┬
· ╰── division by zero
╰────
```
After
```
❯ try { 1 / 0 } catch {|e| echo $"error is ($e)"}
error is {msg: Division by zero., debug: DivisionByZero { span: Span { start: 43104, end: 43105 } }, raw: DivisionByZero { sp
an: Span { start: 43104, end: 43105 } }}
```
As we can see, error becomes a record with `msg`, `debug`, `raw`
columns.
1. msg column is a user friendly message.
2. debug column is more about `Value::Error` information as a string.
3. raw column is a `Value::Error` itself, if user want to re-raise the
error, just use `$e | get raw`

## Summary
This PR lets you use `?` to indicate that a member in a cell path is
optional and Nushell should return `null` if that member cannot be
accessed.
Unlike the previous PR, `?` is now a _postfix_ modifier for cell path
members. A cell path of `.foo?.bar` means that `foo` is optional and
`bar` is not.
`?` does _not_ suppress all errors; it is intended to help in situations
where data has "holes", i.e. the data types are correct but something is
missing. Type mismatches (like trying to do a string path access on a
date) will still fail.
### Record Examples
```bash
{ foo: 123 }.foo # returns 123
{ foo: 123 }.bar # errors
{ foo: 123 }.bar? # returns null
{ foo: 123 } | get bar # errors
{ foo: 123 } | get bar? # returns null
{ foo: 123 }.bar.baz # errors
{ foo: 123 }.bar?.baz # errors because `baz` is not present on the result from `bar?`
{ foo: 123 }.bar.baz? # errors
{ foo: 123 }.bar?.baz? # returns null
```

# Breaking changes
1. Column names with `?` in them now need to be quoted.
2. The `-i`/`--ignore-errors` flag has been removed from `get` and
`select`
1. After this PR, most `get` error handling can be done with `?` and/or
`try`/`catch`.
4. Cell path accesses like this no longer work without a `?`:
```bash
〉[{a:1 b:2} {a:3}].b.0
2
```
We had some clever code that was able to recognize that since we only
want row `0`, it's OK if other rows are missing column `b`. I removed
that because it's tricky to maintain, and now that query needs to be
written like:
```bash
〉[{a:1 b:2} {a:3}].b?.0
2
```
I think the regression is acceptable for now. I plan to do more work in
the future to enable streaming of cell path accesses, and when that
happens I'll be able to make `.b.0` work again.

# Description
The correction made here concerns the issue #8431. Indeed, the algorithm
initially proposed to remove elements of a `vector` performed a loop
with `remove` and an incident therefore appeared when several values
were equal because the deletion was done outside the length of the
vector:
```rust
let mut found = false;
for (i, col) in cols.clone().iter().enumerate() {
if col == col_name {
cols.remove(i);
vals.remove(i);
found = true;
}
}
```
Then, `[[a, a]; [1, 2]] | reject a: ` gave `thread 'main' panicked at
'removal index (is 1) should be < len (is 1)',
crates/nu-protocol/src/value/mod.rs:1213:54`.
The proposed correction is therefore the implementation of the
`retain_mut` utility dedicated to this functionality.
```rust
let mut found = false;
let mut index = 0;
cols.retain_mut(|col| {
if col == col_name {
found = true;
vals.remove(index);
false
} else {
index += 1;
true
}
});
```
