@ -62,3 +62,52 @@ plain strings. User-made splits are respected when they do not exceed the line l
|
||||
limit. Line continuation backslashes are converted into parenthesized strings.
|
||||
Unnecessary parentheses are stripped. The stability and status of this feature is
|
||||
tracked in [this issue](https://github.com/psf/black/issues/2188).
|
||||
|
||||
### Improved line breaks
|
||||
|
||||
For assignment expressions, _Black_ now prefers to split and wrap the right side of the
|
||||
assignment instead of left side. For example:
|
||||
|
||||
```python
|
||||
some_dict[
|
||||
"with_a_long_key"
|
||||
] = some_looooooooong_module.some_looooooooooooooong_function_name(
|
||||
first_argument, second_argument, third_argument
|
||||
)
|
||||
```
|
||||
|
||||
will be changed to:
|
||||
|
||||
```python
|
||||
some_dict["with_a_long_key"] = (
|
||||
some_looooooooong_module.some_looooooooooooooong_function_name(
|
||||
first_argument, second_argument, third_argument
|
||||
)
|
||||
)
|
||||
```
|
||||
|
||||
### Improved parentheses management
|
||||
|
||||
For dict literals with long values, they are now wrapped in parentheses. Unnecessary
|
||||
parentheses are now removed. For example:
|
||||
|
||||
```python
|
||||
my_dict = {
|
||||
my_dict = {
|
||||
"a key in my dict": a_very_long_variable
|
||||
* and_a_very_long_function_call()
|
||||
/ 100000.0,
|
||||
"another key": (short_value),
|
||||
}
|
||||
```
|
||||
|
||||
will be changed to:
|
||||
|
||||
```python
|
||||
my_dict = {
|
||||
"a key in my dict": (
|
||||
a_very_long_variable * and_a_very_long_function_call() / 100000.0
|
||||
),
|
||||
"another key": short_value,
|
||||
}
|
||||
```
