# Description
Fixes: #13105Fixes: #13077
This pr makes `str substring`, `bytes at` work better with negative
index.
And it also fixes the false range semantic on `detect columns -c` in
some cases.
# User-Facing Changes
For `str substring`, `bytes at`, it will no-longer return an error if
start index is larger than end index. It makes sense to return an empty
string of empty bytes directly.
### Before
```nushell
# str substring
❯ ("aaa" | str substring 2..-3) == ""
Error: nu:🐚:type_mismatch
× Type mismatch.
╭─[entry #23:1:10]
1 │ ("aaa" | str substring 2..-3) == ""
· ──────┬──────
· ╰── End must be greater than or equal to Start
2 │ true
╰────
# bytes at
❯ ("aaa" | encode utf-8 | bytes at 2..-3) == ("" | encode utf-8)
Error: nu:🐚:type_mismatch
× Type mismatch.
╭─[entry #27:1:25]
1 │ ("aaa" | encode utf-8 | bytes at 2..-3) == ("" | encode utf-8)
· ────┬───
· ╰── End must be greater than or equal to Start
╰────
```
### After
```nushell
# str substring
❯ ("aaa" | str substring 2..-3) == ""
true
# bytes at
❯ ("aaa" | encode utf-8 | bytes at 2..-3) == ("" | encode utf-8)
true
```
# Tests + Formatting

# Description
Fixes: https://github.com/nushell/nushell/issues/7761
It's still unsure if we want to change the `range semantic` itself, but
it's good to keep range semantic consistent between nushell commands.
# User-Facing Changes
### Before
```nushell
❯ "abc" | str substring 1..=2

```
### After
```nushell

# Tests + Formatting
Adjust tests to fit new behavior
# Description
This PR allows byte streams to optionally be colored as being
specifically binary or string data, which guarantees that they'll be
converted to `Binary` or `String` appropriately on `into_value()`,
making them compatible with `Type` guarantees. This makes them
significantly more broadly usable for command input and output.
There is still an `Unknown` type for byte streams coming from external
commands, which uses the same behavior as we previously did where it's a
string if it's UTF-8.
A small number of commands were updated to take advantage of this, just
to prove the point. I will be adding more after this merges.
# User-Facing Changes
- New types in `describe`: `string (stream)`, `binary (stream)`
- These commands now return a stream if their input was a stream:
- `into binary`
- `into string`
- `bytes collect`
- `str join`
- `first` (binary)
- `last` (binary)
- `take` (binary)
- `skip` (binary)
- Streams that are explicitly binary colored will print as a streaming
hexdump
- example:
```nushell
1.. | each { into binary } | bytes collect
```
# Tests + Formatting
I've added some tests to cover it at a basic level, and it doesn't break
anything existing, but I do think more would be nice. Some of those will
come when I modify more commands to stream.
# After Submitting
There are a few things I'm not quite satisfied with:
- **String trimming behavior.** We automatically trim newlines from
streams from external commands, but I don't think we should do this with
internal commands. If I call a command that happens to turn my string
into a stream, I don't want the newline to suddenly disappear. I changed
this to specifically do it only on `Child` and `File`, but I don't know
if this is quite right, and maybe we should bring back the old flag for
`trim_end_newline`
- **Known binary always resulting in a hexdump.** It would be nice to
have a `print --raw`, so that we can put binary data on stdout
explicitly if we want to. This PR doesn't change how external commands
work though - they still dump straight to stdout.
Otherwise, here's the normal checklist:
- [ ] release notes
- [ ] docs update for plugin protocol changes (added `type` field)

# Description
Judiciously try to avoid allocations/clone by changing the signature of
functions
- **Don't pass str by value unnecessarily if only read**
- **Don't require a vec in `Sandbox::with_files`**
- **Remove unnecessary string clone**
- **Fixup unnecessary borrow**
- **Use `&str` in shape color instead**
- **Vec -> Slice**
- **Elide string clone**
- **Elide `Path` clone**
- **Take &str to elide clone in tests**

# 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
👉 before
```nushell
~ l> "ὈΔΥΣΣΕΎΣ" | str downcase
ὈΔΥΣΣΕΎΣ
```
👉 after
```nushell
~ l> "ὈΔΥΣΣΕΎΣ" | str downcase
ὀδυσσεύς

# After Submitting
# Description
We made the decision that our floating point type should be referred to
as `float` over `decimal`.
Commands were updated by #9979 and #10320
Now make the internal codebase consistent in referring to this data type
as `float`.
Work for #10332
# User-Facing Changes
`decimal` has been removed as a type name/symbol.
Instead of
```nushell
def foo [bar: decimal] decimal -> decimal {}
```
use
```nushell
def foo [bar: float] float -> float {}
```
Potential effect of `SyntaxShape`'s `Display` implementation now also
referring to `float` instead of `decimal`
# Details
- Rename `SyntaxShape::Decimal` to `Float`
- Update `Display for SyntaxShape` to `float`
- Update error message + fn name in dataframe code
- Fix docs in command examples
- Rename tests that are float specific
- Update doccomment on `SyntaxShape`
- Update comment in script
# Tests + Formatting
Updates the names of some tests
# Description
We keep "into decimal" for a release and warn through a message that it
will be removed in 0.86.
All tests are updated to use `into float`
# User-Facing Changes
`into decimal` raises a deprecation warning, will be removed soon.
Use `into float` as the new functionally identical command instead.

I am moving the following str case commands to nu-cmd-extra (as
discussed in the core team meeting the other day)
* camel-case
* kebab-case
* pascal-case
* screaming-snake-case
* snake-case
* title-case
# Description
The working directory doesn't have to be set for those tests (or would
be the default anyways). When appropriate also remove calls to the
`pipeline()` function. In most places kept the diff minimal and only
removed the superfluous part to not pollute the blame view. With simpler
tests also simplified things to make them more readable overall (this
included removal of the raw string literal).
Work for #8670
# 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.
# User-Facing Changes
Removes the array and string forms of ranges from `str substring`.
Leaves only the official range support for range values.

# 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.

Just making sure we see this for release notes 😅
This breaks any and all numberlike values that were treated as strings
before. Example, we used to allow `3,` as a bare word. Anything like
this would now require quotes or backticks to be treated as a string or
bare word, respectively.

`ShellError::UnsupportedInput` with this error. 'Incorrect value' is
different from 'wrong type'
