# Description
Empty cells were being skipped, causing data to appear in the wrong
columns. By including the cells, data should appear in the correct
columns now. Fixes#10194.
Before:
```
$ [[a b c]; [1 null 3] [4 5 6]] | to html --partial | query web --as-table [a b c]
╭───┬───┬───┬─────────────────────╮

```
After:
```
$ [[a b c]; [1 null 3] [4 5 6]] | to html --partial | query web --as-table [a b c]
╭───┬───┬───┬───╮

Original implementation contains multiple `expect` which can cause
internal runtime panic.
This pr forks the `css` selector impl and make it return an error that
nushell can recognize.
**Note:** The original impl is still used in pre-defined selector
implementations, but they
should never fail, so the `css` fn is preserved.
Closes#13496.

# Description
This PR adds a new subcommand `query webpage-info` to `plugin_nu_query`.
The subcommand is a basic wrapper for the
[`webpage`](https://crates.io/crates/webpage) crate.
Usage:
```
http get https://phoronix.com | query webpage-info
```
and it returns a `Record` version of
[`webpage::HTML`](https://docs.rs/webpage/latest/webpage/struct.HTML.html).
The PR also takes a shot at bringing @lily-mara 's
[nu-serde::to_value](https://github.com/nushell/nushell/pull/3878/files)
back to life, updating it for the latest version of nushell. That's not
the main focus of the PR though - I just didn't want to have to
implement a custom converter for `webpage::HTML` 😅. If it looks
reasonable we could move it to `nu_protocol`(?) either in this PR or a
future one (along with adding tests for it).
# User-Facing Changes

# Description
Allows specifying multiple attributes to retrieve from the selected

# User-Facing Changes
`query web --attribute` previously accepted a string. Now it accepts
either a string or a list of strings.
The shape definition for this flag was relaxed temporarily, until
nushell/nushell#13253 is fixed.

# Description
This allows plugins to report their version (and potentially other
metadata in the future). The version is shown in `plugin list` and in
`version`.
The metadata is stored in the registry file, and reflects whatever was
retrieved on `plugin add`, not necessarily the running binary. This can
help you to diagnose if there's some kind of mismatch with what you
expect. We could potentially use this functionality to show a warning or
error if a plugin being run does not have the same version as what was
in the cache file, suggesting `plugin add` be run again, but I haven't
done that at this point.
It is optional, and it requires the plugin author to make some code
changes if they want to provide it, since I can't automatically
determine the version of the calling crate or anything tricky like that
to do it.
Example:
```
> plugin list | select name version is_running pid
╭───┬────────────────┬─────────┬────────────┬─────╮
│ # │ name │ version │ is_running │ pid │

# Description
This is something that was discussed in the core team meeting last
Wednesday. @ayax79 is building `nu-plugin-polars` with all of the
dataframe commands into a plugin, and there are a lot of them, so it
would help to make the API more similar. At the same time, I think the
`Command` API is just better anyway. I don't think the difference is
justified, and the types for core commands have the benefit of requiring
less `.into()` because they often don't own their data
- Broke `signature()` up into `name()`, `usage()`, `extra_usage()`,
`search_terms()`, `examples()`
- `signature()` returns `nu_protocol::Signature`
- `examples()` returns `Vec<nu_protocol::Example>`
- `PluginSignature` and `PluginExample` no longer need to be used by
plugin developers
# User-Facing Changes
Breaking API for plugins yet again 😄
# Description
When implementing a `Command`, one must also import all the types
present in the function signatures for `Command`. This makes it so that
we often import the same set of types in each command implementation
file. E.g., something like this:
```rust
use nu_protocol::ast::Call;
use nu_protocol::engine::{Command, EngineState, Stack};
use nu_protocol::{
record, Category, Example, IntoInterruptiblePipelineData, IntoPipelineData, PipelineData,
ShellError, Signature, Span, Type, Value,
};
```
This PR adds the `nu_engine::command_prelude` module which contains the
necessary and commonly used types to implement a `Command`:
```rust
// command_prelude.rs
pub use crate::CallExt;
pub use nu_protocol::{
ast::{Call, CellPath},
engine::{Command, EngineState, Stack},
record, Category, Example, IntoInterruptiblePipelineData, IntoPipelineData, IntoSpanned,
PipelineData, Record, ShellError, Signature, Span, Spanned, SyntaxShape, Type, Value,
};
```
This should reduce the boilerplate needed to implement a command and
also gives us a place to track the breadth of the `Command` API. I tried
to be conservative with what went into the prelude modules, since it
might be hard/annoying to remove items from the prelude in the future.
Let me know if something should be included or excluded.
# Description
There wasn't really a good way to implement a command group style (e.g.
`from`, `query`, etc.) command in the past that just returns the help
text even if `--help` is not passed. This adds a new engine call that
just does that.
This is actually something I ran into before when developing the dbus
plugin, so it's nice to fix it.

# Description
This makes `LabeledError` much more capable of representing close to
everything a `miette::Diagnostic` can, including `ShellError`, and
allows plugins to generate multiple error spans, codes, help, etc.
`LabeledError` is now embeddable within `ShellError` as a transparent
variant.
This could also be used to improve `error make` and `try/catch` to
reflect `LabeledError` exactly in the future.
Also cleaned up some errors in existing plugins.

[Context on
Discord](https://discord.com/channels/601130461678272522/855947301380947968/1216517833312309419)
# Description
This is a significant breaking change to the plugin API, but one I think
is worthwhile. @ayax79 mentioned on Discord that while trying to start
on a dataframes plugin, he was a little disappointed that more wasn't
provided in terms of code organization for commands, particularly since
there are *a lot* of `dfr` commands.
This change treats plugins more like miniatures of the engine, with
dispatch of the command name being handled inherently, each command
being its own type, and each having their own signature within the trait
impl for the command type rather than having to find a way to centralize
it all into one `Vec`.
For the example plugins that have multiple commands, I definitely like
how this looks a lot better. This encourages doing code organization the
right way and feels very good.
For the plugins that have only one command, it's just a little bit more
boilerplate - but still worth it, in my opinion.
The `Box<dyn PluginCommand<Plugin = Self>>` type in `commands()` is a
little bit hairy, particularly for Rust beginners, but ultimately not so
bad, and it gives the desired flexibility for shared state for a whole
plugin + the individual commands.
# User-Facing Changes
Pretty big breaking change to plugin API, but probably one that's worth
making.
```rust
use nu_plugin::*;
use nu_protocol::{PluginSignature, PipelineData, Type, Value};
struct LowercasePlugin;
struct Lowercase;
// Plugins can now have multiple commands
impl PluginCommand for Lowercase {
type Plugin = LowercasePlugin;
// The signature lives with the command
fn signature(&self) -> PluginSignature {
PluginSignature::build("lowercase")
.usage("Convert each string in a stream to lowercase")
.input_output_type(Type::List(Type::String.into()), Type::List(Type::String.into()))
}
// We also provide SimplePluginCommand which operates on Value like before
fn run(
&self,
plugin: &LowercasePlugin,
engine: &EngineInterface,
call: &EvaluatedCall,
input: PipelineData,
) -> Result<PipelineData, LabeledError> {
let span = call.head;
Ok(input.map(move |value| {
value.as_str()
.map(|string| Value::string(string.to_lowercase(), span))
// Errors in a stream should be returned as values.
.unwrap_or_else(|err| Value::error(err, span))
}, None)?)
}
}
// Plugin now just has a list of commands, and the custom value op stuff still goes here
impl Plugin for LowercasePlugin {
fn commands(&self) -> Vec<Box<dyn PluginCommand<Plugin=Self>>> {
vec![Box::new(Lowercase)]
}
}
fn main() {
serve_plugin(&LowercasePlugin{}, MsgPackSerializer)
}
```
Time this however you like - we're already breaking stuff for 0.92, so
it might be good to do it now, but if it feels like a lot all at once,
it could wait.

change
# Description
This allows plugins to make calls back to the engine to get config,
evaluate closures, and do other things that must be done within the
engine process.
Engine calls can both produce and consume streams as necessary. Closures
passed to plugins can both accept stream input and produce stream output
sent back to the plugin.
Engine calls referring to a plugin call's context can be processed as
long either the response hasn't been received, or the response created
streams that haven't ended yet.
This is a breaking API change for plugins. There are some pretty major
changes to the interface that plugins must implement, including:
1. Plugins now run with `&self` and must be `Sync`. Executing multiple
plugin calls in parallel is supported, and there's a chance that a
closure passed to a plugin could invoke the same plugin. Supporting
state across plugin invocations is left up to the plugin author to do in
whichever way they feel best, but the plugin object itself is still
shared. Even though the engine doesn't run multiple plugin calls through
the same process yet, I still considered it important to break the API
in this way at this stage. We might want to consider an optional
threadpool feature for performance.
2. Plugins take a reference to `EngineInterface`, which can be cloned.
This interface allows plugins to make calls back to the engine,
including for getting config and running closures.
3. Plugins no longer take the `config` parameter. This can be accessed
from the interface via the `.get_plugin_config()` engine call.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
Not only does this have plugin protocol changes, it will require plugins
to make some code changes before they will work again. But on the plus
side, the engine call feature is extensible, and we can add more things
to it as needed.
Plugin maintainers will have to change the trait signature at the very
least. If they were using `config`, they will have to call
`engine.get_plugin_config()` instead.
If they were using the mutable reference to the plugin, they will have
to come up with some strategy to work around it (for example, for `Inc`
I just cloned it). This shouldn't be such a big deal at the moment as
it's not like plugins have ever run as daemons with persistent state in
the past, and they don't in this PR either. But I thought it was
important to make the change before we support plugins as daemons, as an
exclusive mutable reference is not compatible with parallel plugin
calls.
I suggest this gets merged sometime *after* the current pending release,
so that we have some time to adjust to the previous plugin protocol
changes that don't require code changes before making ones that do.

I will document the additional protocol features (`EngineCall`,
`EngineCallResponse`), and constraints on plugin call processing if
engine calls are used - basically, to be aware that an engine call could
result in a nested plugin call, so the plugin should be able to handle
that.
# Description
Following #11851, this PR adds one final conversion function for
`Value`. `Value::coerce_str` takes a `&Value` and converts it to a
`Cow<str>`, creating an owned `String` for types that needed converting.
Otherwise, it returns a borrowed `str` for `String` and `Binary`
`Value`s which avoids a clone/allocation. Where possible, `coerce_str`
and `coerce_into_string` should be used instead of `coerce_string`,
since `coerce_string` always allocates a new `String`.
# Description
This PR renames the conversion functions on `Value` to be more consistent.
It follows the Rust [API guidelines](https://rust-lang.github.io/api-guidelines/naming.html#ad-hoc-conversions-follow-as_-to_-into_-conventions-c-conv) for ad-hoc conversions.
The conversion functions on `Value` now come in a few forms:
- `coerce_{type}` takes a `&Value` and attempts to convert the value to
`type` (e.g., `i64` are converted to `f64`). This is the old behavior of
some of the `as_{type}` functions -- these functions have simply been
renamed to better reflect what they do.
- The new `as_{type}` functions take a `&Value` and returns an `Ok`
result only if the value is of `type` (no conversion is attempted). The
returned value will be borrowed if `type` is non-`Copy`, otherwise an
owned value is returned.
- `into_{type}` exists for non-`Copy` types, but otherwise does not
attempt conversion just like `as_type`. It takes an owned `Value` and
always returns an owned result.
- `coerce_into_{type}` has the same relationship with `coerce_{type}` as
`into_{type}` does with `as_{type}`.
- `to_{kind}_string`: conversion to different string formats (debug,
abbreviated, etc.). Only two of the old string conversion functions were
removed, the rest have been renamed only.
- `to_{type}`: other conversion functions. Currently, only `to_path`
exists. (And `to_string` through `Display`.)
This table summaries the above:
| Form | Cost | Input Ownership | Output Ownership | Converts `Value`
case/`type` |
| ---------------------------- | ----- | --------------- |
---------------- | -------- |
| `as_{type}` | Cheap | Borrowed | Borrowed/Owned | No |
| `into_{type}` | Cheap | Owned | Owned | No |
| `coerce_{type}` | Cheap | Borrowed | Borrowed/Owned | Yes |
| `coerce_into_{type}` | Cheap | Owned | Owned | Yes |
| `to_{kind}_string` | Expensive | Borrowed | Owned | Yes |
| `to_{type}` | Expensive | Borrowed | Owned | Yes |

## Problem
I tried converting one of my Rust web scrapers to Nushell just to see
how it would be done, but quickly ran into an issue that proved annoying
to fix without diving into the source.
For instance, let's say we have the following HTML
```html
<p>Hello there, <span style="color: red;">World</span></p>
```
and we want to extract only the text within the `p` element, but not the
`span`. With the current version of nu_plugin_query, if we run this code
```nushell
echo `<p>Hello there, <span style="color: red;">World</span></p>` | query web -q "p" | get 0
# returns "Hello there, World"
# but we want only "Hello there, "
```
we will get back a `list<string>` that contains 1 string `Hello there,
World`.
To avoid scraping the span, we would have to do something like this
```nushell
const html = `<p>Hello there, <span style="color: red;">World</span></p>`
$html
| query web -q "p"
| get 0
| str replace ($html | query web -q "p > span" | get 0) ""
# returns "Hello there, "
```
In other words, we would have to make a sub scrape of the text we
*don't* want in order to subtract it from the text we *do* want.
## Solution
I didn't like this behavior, so I decided to change it. I modified the
`execute_selector_query` function to collect all text nodes in the HTML
element matching the query. Now `query web --query` will return a
`list<list<string>>`
```nushell
echo `<p>Hello there, <span style="color: red;">World</span></p>` | query web -q "p" | get 0 | to json --raw
# returns ["Hello there, ","World"]
```
This also brings `query web --query`'s behavior more in line with
[scraper's
ElementRef::text()](https://docs.rs/scraper/latest/scraper/element_ref/struct.ElementRef.html#method.text)
which "Returns an iterator over descendent text nodes", allowing you to
choose how much of an element's text you want to scrape without
resorting to string substitutions.
## Consequences
As this is a user-facing change, the usage examples will produce
different results than before. For example
```nushell
http get https://phoronix.com | query web --query 'header'
```
will return a list of lists of 1 string each, whereas before it was just
a list of strings.
I only modified the 3rd example
```nushell
# old
http get https://www.nushell.sh | query web --query 'h2, h2 + p' | group 2 | each {rotate --ccw tagline description} | flatten
# new
http get https://www.nushell.sh | query web --query 'h2, h2 + p' | each {str join} | group 2 | each {rotate --ccw tagline description} | flatten
```
to make it behave like before because I thought this one ought to show
the same results as before.
However, the second reason I changed the 3rd example is because it
otherwise panics! If we run the original 3rd example with my
modifications, we get a panic
```
thread 'main' panicked at crates/nu-protocol/src/value/record.rs:34:9:
assertion `left == right` failed
left: 2
right: 17
```
This happens because `rotate` receives a list of lists where the inner
lists have a different number of elements.
However this panic is unrelated to the changes I've made, because it can
be triggered easily without using the plugin. For instance
```nushell
# this is fine
[[[one] [two]] [[three] [four]]] | each {rotate --ccw tagline description}
# this panics!
[[[one] [two]] [[three] [four five]]] | each {rotate --ccw tagline description}
```
Though beyond the scope of this PR, I thought I'd mention this bug since
I found it while testing the usage examples. However, I intend to make a
proper issue about it tomorrow.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This

`query web --query "css selector"` now returns a `list<list<string>>`
instead of a `list<string>` to make it more in line with [scraper's
ElementRef::text()](https://docs.rs/scraper/latest/scraper/element_ref/struct.ElementRef.html#method.text).

# Description
This PR tries to make `query web` more resilient and easier to debug
with the `--inspect` parameter when trying to scrape tables. Previously
it would just fail, now at least it tries to give you a hint.
This is some example output now of when something went wrong.

The key here is to look at the `Passed in Column Headers` and compare
them to the `Potential HTML Headers` and couple that with the error
table at the bottom should give you a hint that, in this situation,
wikipedia has changed the column names, yet again. So we need to update
our query web statement's tables to get closer to what we want.

# Description
#11492 fixed flags for builtin commands but I missed that plugins don't
use the same `has_flag` that builtins do. This PR addresses this.
Unfortunately this means that return value of `has_flag` needs to change
from `bool` to `Result<bool, ShellError>` to produce an error when
explicit value is not a boolean (just like in case of `has_flag` for
builtin commands. It is not possible to check this in
`EvaluatedCall::try_from_call` because
# User-Facing Changes
Passing explicit values to flags of plugin commands (like `--flag=true`
`--flag=false`) should work now.
BREAKING: changed return value of `EvaluatedCall::has_flag` method from
`bool` to `Result<bool, ShellError>`
# Tests + Formatting
Added tests and updated documentation and examples
# Description
When nushell calls a plugin it now sends a configuration `Value` from
the nushell config under `$env.config.plugins.PLUGIN_SHORT_NAME`. This
allows plugin authors to read configuration provided by plugin users.
The `PLUGIN_SHORT_NAME` must match the registered filename after
`nu_plugin_`. If you register `target/debug/nu_plugin_config` the
`PLUGIN_NAME` will be `config` and the nushell config will loook like:
$env.config = {
# ...
plugins: {
config: [
some
values
]
}
}
Configuration may also use a closure which allows passing values from
`$env` to a plugin:
$env.config = {
# ...
plugins: {
config: {||
$env.some_value
}
}
}
This is a breaking change for the plugin API as the `Plugin::run()`
function now accepts a new configuration argument which is an
`&Option<Value>`. If no configuration was supplied the value is `None`.
Plugins compiled after this change should work with older nushell, and
will behave as if the configuration was not set.
Initially discussed in #10867
# User-Facing Changes
* Plugins can read configuration data stored in `$env.config.plugins`
* The plugin `CallInfo` now includes a `config` entry, existing plugins
will require updates
