# User-Facing Changes

**BREAKING CHANGES**

This removes the `&&` and `||` operators. We previously supported by
`&&`/`and` and `||`/`or`. With this change, only `and` and `or` are
valid boolean operators.

# Description
Closes #7059. Rather than generate a new Record each time $env.config is
accessed (as described in that issue), instead `$env.config = ` now A)
parses the input record, then B) un-parses it into a clean Record with
only the valid values, and stores that as an env-var. The reasoning for
this is that I believe `config_to_nu_record()` (the method that performs
step B) will be useful in later PRs. (See below)

As a result, this also "fixes" the following "bug":
```
〉$env.config = 'butts'
$env.config is not a record
〉$env.config
butts
```
~~Instead, `$env.config = 'butts'` now turns `$env.config` into the
default (not the default config.nu, but `Config::default()`, which
notably has empty keybindings, color_config, menus and hooks vecs).~~

This doesn't attempt to fix #7110. cc @Kangaxx-0

…ypeMismatch and add spans to every instance of the former (#7217)

# Description

* I was dismayed to discover recently that UnsupportedInput and
TypeMismatch are used *extremely* inconsistently across the codebase.
UnsupportedInput is sometimes used for input type-checks (as per the
name!!), but *also* used for argument type-checks. TypeMismatch is also
used for both.
I thus devised the following standard: input type-checking *only* uses
UnsupportedInput, and argument type-checking *only* uses TypeMismatch.
Moreover, to differentiate them, UnsupportedInput now has *two* error
arrows (spans), one pointing at the command and the other at the input
origin, while TypeMismatch only has the one (because the command should
always be nearby)
* In order to apply that standard, a very large number of
UnsupportedInput uses were changed so that the input's span could be
retrieved and delivered to it.
* Additionally, I noticed many places where **errors are not propagated
correctly**: there are lots of `match` sites which take a Value::Error,
then throw it away and replace it with a new Value::Error with
less/misleading information (such as reporting the error as an
"incorrect type"). I believe that the earliest errors are the most
important, and should always be propagated where possible.
* Also, to standardise one broad subset of UnsupportedInput error
messages, who all used slightly different wordings of "expected
`<type>`, got `<type>`", I created OnlySupportsThisInputType as a
variant of it.
* Finally, a bunch of error sites that had "repeated spans" - i.e. where
an error expected two spans, but `call.head` was given for both - were
fixed to use different spans.

EDIT: This also changes the semantics of `get`/`select` `-i` somewhat.
I've decided to leave it like this because it works more intuitively
with `default` and `compact`.
BEFORE:
```
〉[{a:1} {b:2} {a:3}] | select -i foo | to nuon
null

```

# User-Facing Changes

See above. EDIT: the issue with holes in cases like ` [{foo: 'bar'}
{}].foo.0` versus ` [{foo: 'bar'} {}].0.foo` has been resolved.

# Description

This PR will help report a bad date that can't be converted where the
error message says `* Unable to parse datetime`. This is helpful when
you're converting a big table and it fails somewhere that you really
can't see. I put it in `[]` so that when it's null, you can see that
there should be something there.

fdncred added a commit that referenced this pull request Feb 9, 2023
# Description

This PR does the following:
1. Adds a new command called `view span` - which shows what is at the
location of the span parameters
2. Adds a new command called `view` - which just lists all the `view`
commands.
3. Renames `view-source` to `view source`.
4. Adds a new command called `view files` - which shows you what files
are loaded into nushell's EngineState memory.
5. Added a `Category::Debug` and put these commands (and others) into
it. (`inspect` needs to be added to it, but it's not landed yet)

Spans are important to nushell. One of their uses is to show where
errors are. For instance, in this example, the leader lines pointing to
parts of the command line are able to point to `10`, `/`, and `"bob"`
because each of those items have a span.
```
> 10 / "bob"

# Examples

## view span
Example:
```
> $env.config | get keybindings | first | debug -r
... bunch of stuff
                    span: Span {
                        start: 68065,
                        end: 68090,
                    },
                },
            ],
            span: Span {
                start: 68050,
                end: 68101,
            },
        },
    ],
    span: Span {
        start: 67927,
        end: 68108,
    },
}
```
To view the last span:
```

        modifier: control
        keycode: char_l
        mode: emacs
        event: [
            { send: clearscrollback }
        ]
    }
```
> To view the 2nd to last span:
```
view span 68065 68090
{ send: clearscrollback }
```
> To view the 3rd to last span:

`entry #x` will be each command you type in the repl (i think). so, it
may be good to filter those out sometimes.

# Description

Fix a regression introduced by #12921, where tilde expansion was no
longer done on the external command name, breaking things like

```nushell
> ~/.cargo/bin/exa
```

This properly handles quoted strings, so they don't expand:

```nushell
> ^"~/.cargo/bin/exa"
Error: nu::shell::external_command

  × External command failed
   ╭─[entry #1:1:2]
 1 │ ^"~/.cargo/bin/exa"
   ·  ─────────┬────────
   ·           ╰── Command `~/.cargo/bin/exa` not found
   ╰────
  help: `~/.cargo/bin/exa` is neither a Nushell built-in or a known external command

```

This required a change to the parser, so the command name is also parsed
in the same way the arguments are - i.e. the quotes on the outside
remain in the expression. Hopefully that doesn't break anything else. 🤞

Fixes #13000. Should include in patch release 0.94.1

cc @YizhePKU

# User-Facing Changes
- Tilde expansion now works again for external commands
- The `command` of `run-external` will now have its quotes removed like
the other arguments if it is a literal string
- The parser is changed to include quotes in the command expression of
`ExternalCall` if they were present

# Tests + Formatting
I would like to add a regression test for this, but it's complicated
because we need a well-known binary within the home directory, which
just isn't a thing. We could drop one there, but that's kind of a bad
behavior for a test to do. I also considered changing the home directory
for the test, but that's so platform-specific - potentially could get it
working on specific platforms though. Changing `HOME` env on Linux
definitely works as far as tilde expansion works.

# Description

As part of fixing #13586, this
PR checks the types of the operands when creating a range. Stuff like
`0..(glob .)` will be rejected at parse time. Additionally, `0..$x` will
be treated as a range and rejected if `x` is not defined, rather than
being treated as a string. A separate PR will need to be made to do
reject streams at runtime, so that stuff like `0..(open /dev/random)`
doesn't hang.

Internally, this PR adds a `ParseError::UnsupportedOperationTernary`
variant, for when you have a range like `1..2..(glob .)`.

# User-Facing Changes

Users will now receive an error if any of the operands in the ranges
they construct have types that aren't compatible with `Type::Number`.

Additionally, if a piece of code looks like a range but some parse error
is encountered while parsing it, that piece of code will still be
treated as a range and the user will be shown the parse error. This
means that a piece of code like `0..$x` will be treated as a range no
matter what. Previously, if `x` weren't the expression would've been
treated as a string `"0..$x"`. I feel like it makes the language less
complicated if we make it less context-sensitive.

Here's an example of the error you get:
```
> 0..(glob .)
Error: nu::parser::unsupported_operation

  × range is not supported between int and any.
   ╭─[entry #1:1:1]
 1 │ 0..(glob .)
   · ─────┬─────┬┬
   ·      │     │╰── any
   ·      │     ╰── int
   ·      ╰── doesn't support these values
   ╰────
```

And as an image:

![image](https://github.com/user-attachments/assets/5c76168d-27db-481b-b541-861dac899dbf)

Note: I made the operands themselves (above, `(glob .)`) be garbage,
rather than the `..` operator itself. This doesn't match the behavior of
the math operators (if you do `1 + "foo"`, `+` gets highlighted red).
This is because with ranges, the range operators aren't `Expression`s
themselves, so they can't be turned into garbage. I felt like here, it
makes more sense to highlight the individual operand anyway.

# Description
This PR makes it so that non-zero exit codes and termination by signal
are treated as a normal `ShellError`. Currently, these are silent
errors. That is, if an external command fails, then it's code block is
aborted, but the parent block can sometimes continue execution. E.g.,
see #8569 and this example:
```nushell
[1 2] | each { ^false }
```

Before this would give:
```
╭───┬──╮
│ 0 │  │
│ 1 │  │
╰───┴──╯
```

Now, this shows an error:
```
Error: nu::shell::eval_block_with_input

  × Eval block failed with pipeline input
   ╭─[entry #1:1:2]
 1 │ [1 2] | each { ^false }
   ·  ┬
   ·  ╰── source value
   ╰────

Error: nu:🐚:non_zero_exit_code

  × External command had a non-zero exit code
   ╭─[entry #1:1:17]
 1 │ [1 2] | each { ^false }
   ·                 ──┬──
   ·                   ╰── exited with code 1
   ╰────
```

This PR fixes #12874, fixes #5960, fixes #10856, and fixes #5347. This
PR also partially addresses #10633 and #10624 (only the last command of
a pipeline is currently checked). It looks like #8569 is already fixed,
but this PR will make sure it is definitely fixed (fixes #8569).

# User-Facing Changes
- Non-zero exit codes and termination by signal now cause an error to be
thrown.
- The error record value passed to a `catch` block may now have an
`exit_code` column containing the integer exit code if the error was due
to an external command.
- Adds new config values, `display_errors.exit_code` and
`display_errors.termination_signal`, which determine whether an error
message should be printed in the respective error cases. For
non-interactive sessions, these are set to `true`, and for interactive
sessions `display_errors.exit_code` is false (via the default config).

# Tests
Added a few tests.

# After Submitting
- Update docs and book.
- Future work:
- Error if other external commands besides the last in a pipeline exit
with a non-zero exit code. Then, deprecate `do -c` since this will be
the default behavior everywhere.
- Add a better mechanism for exit codes and deprecate
`$env.LAST_EXIT_CODE` (it's buggy).

# Description
Old code was comparing remaining positional arguments with total number
of arguments, where it should've compared remaining positional with
with remaining arguments of any kind. This means that if a function was
given too few arguments, `calculate_end_span` would believe that it
actually had too many arguments, since after parsing the first few
arguments, the number of remaining arguments needed were fewer than the
*total* number of arguments, of which we had used several.

Fixes #9072
Fixes: #13930
Fixes: #12069
Fixes: #8385

Extracted from #10381

## Bonus

It also improves the error handling on missing positional arguments
before keywords (no longer crashing since #9851). Instead of just giving
the keyword to the parser for the missing positional, we give an
explicit error about a missing positional argument. I would like better
descriptions than "missing var_name" though, but I'm not sure if that's
available without

Old error

This PR fixes the quoting and escaping of column names in `to nuon`.
Before the PR, column names with quotes inside them would get quoted,
but not escaped:

The cause of the issue was that `to nuon` simply wrapped column names in
`'"'` instead of calling `escape_quote_string`.

As part of this change, I also moved the functions related to quoting
(`needs_quoting` and `escape_quote_string`) into `nu-utils`, since
previously they were defined in very ad-hoc places (and, in the case of
`escape_quote_string`, it was defined multiple times with the same
body!).

`to nuon` now properly escapes quotes in column names.

# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use toolkit.nu; toolkit test stdlib"` to run the
tests for the standard library

> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr
> ```
-->

All tests pass, including workspace and stdlib tests.

# After Submitting
<!-- If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.

# User-Facing Changes

- Special characters in module names are replaced with underscores when
  importing constants, preventing "expected valid variable name":

```nushell
> module foo-bar { export const baz = 1 }
> use foo-bar
> $foo_bar.baz
```

- "expected valid variable name" errors now include a suggestion list:

```nushell
> module foo-bar { export const baz = 1 }
> use foo-bar
> $foo-bar
Error: nu::parser::parse_mismatch_with_did_you_mean
