pitrou opened a new pull request #11955:
URL: https://github.com/apache/arrow/pull/11955
This makes compute functions easier to use, for example here the required
"pattern" option doesn't need to be passed by name:
```
>>> pc.split_pattern("abacab", "a")
<pyarrow.ListScalar: ['', 'b', 'c', 'b']>
```
... and producing the following doc at the prompt:
```
split_pattern(strings, /, pattern, *, max_splits=-1, reverse=False,
options=None, memory_pool=None)
Split string according to separator.
Split each string according to the exact `pattern` defined in
SplitPatternOptions. The output for each string input is a list
of strings.
The maximum number of splits and direction of splitting
(forward, reverse) can optionally be defined in SplitPatternOptions.
Parameters
----------
strings : Array-like or scalar-like
Argument to compute function
pattern : optional
Parameter for SplitPatternOptions constructor. Either `options`
or `pattern` can be passed, but not both at the same time.
max_splits : optional
Parameter for SplitPatternOptions constructor. Either `options`
or `max_splits` can be passed, but not both at the same time.
reverse : optional
Parameter for SplitPatternOptions constructor. Either `options`
or `reverse` can be passed, but not both at the same time.
options : pyarrow.compute.SplitPatternOptions, optional
Parameters altering compute function semantics.
memory_pool : pyarrow.MemoryPool, optional
If not passed, will allocate memory from the default memory pool.
