# Description
Fix the docs repo CI build error here:
https://github.com/nushell/nushell.github.io/actions/runs/12425087184/job/34691291790#step:5:18
The doc generated by `make_docs.nu` for `polars profile` command will
make the CI build fail due to the indention error of markdown front
matters. I used to fix it manually before, for the long run, it's better
to fix it from the source code.
- fixes#14572
# Description
This allowed columns to be coalesced on full joins with `polars join`,
providing functionality simlar to the old `--outer` join behavior.
# User-Facing Changes
- Provides a new flag `--coalesce-columns` on the `polars join` command
Addresses some null handling issues in #6882
# Description
This changes the implementation of guessing a column type when a schema
is not specified.
New behavior:
1. Use the first non-Value::Nothing value type for the columns data type
2. If the value type changes (ignoring Value::Nothing) in subsequent
values, the datatype will be changed to DataType::Object("Value", None)
3. If a column type does not have a value type,
DataType::Object("Value", None) will be assumed.
The `--name` flag of `polars with-column` only works when used with an
eager dataframe. I will not work with lazy dataframes and it will not
work when used with expressions (which forces a conversion to a
lazyframe). This pull request adds better documentation to the flags and
errors messages when used in cases where it will not work.

Adds support for converting from polars decimal type to nushell values.
This fix works by first converting a polars decimal series to an f64
series, then converting to Value::Float

# Description
This PR fixes a problem where not equal in polars wasn't working with
strings.
## Before

let a = ls | polars into-df
$a.type != "dir"
Error: nu:🐚:type_mismatch
× Type mismatch during operation.
╭─[entry #16:1:1]
1 │ $a.type != "dir"
· ─┬ ─┬ ──┬──
· │ │ ╰── string
· │ ╰── type mismatch for operator
· ╰── NuDataFrame

```
## After
```nushell
let a = ls | polars into-df
$a.type != "dir"
╭──#──┬─type──╮
│ 0 │ false │
│ 1 │ false │
│ 2 │ false │

# Description
Turns out there are duplicate conversion functions: `as_i64` and
`as_f64`. In most cases, these can be replaced with `as_int` and
`as_float`, respectively.

# Description
This fixes an issue with converting to a dataframe when specifying a
struct in the schema. Things like the following now work correctly:
```nushell
[[foo bar]; [{a: "a_0", b:"b_0"} 1] [{a: "a_1", b: "b_1" } 2]] | polars into-df -s {foo: {a: str, b: str}, bar: u8}
```
# Description
Introduces a new flag `--truncate-ragged-lines` for `polars open` that
will truncate lines that are longer than the schema.
# User-Facing Changes
- Introduction of the flag `--truncate-ragged-lines` for `polars open`
# Description
This request exposes the prelude::polars::len expression. It is ended
for doing fast select count(*) like operations:
<img width="626" alt="Screenshot 2024-09-26 at 18 14 45"
src="https://github.com/user-attachments/assets/74285fc6-f99c-46e0-9226-9a7d41738d78">
# User-Facing Changes
- Introduction of the `polars len` command
# Description
This adds support for reading and writing binary types in the polars
commands.
The `BinaryOffset` type can be read into a Nushell native `Value` type
no problem, but unfortunately this is a lossy conversion, as there's
no Nushell-native semantic equivalent to the fixed size binary type
in Arrow.
# User-Facing Changes
`polars open` and `polars save` now work with binary types.
