Sasmitha Manathunga	0c7a5cb206	Fix inconsistent behavior of `CharacterTextSplitter` when changing `keep_separator` (#7263 ) - Description: - When `keep_separator` is `True` the `_split_text_with_regex()` method in `text_splitter` uses regex to split, but when `keep_separator` is `False` it uses `str.split()`. This causes problems when the separator is a special regex character like `.` or `*`. This PR fixes that by using `re.split()` in both cases. - Issue: #7262 - Tag maintainer: @baskaryan	1 year ago

Thomas B	ac3e6e3944	Fix IndexError in RecursiveCharacterTextSplitter (#5902 ) Fixes (not reported) an error that may occur in some cases in the RecursiveCharacterTextSplitter. An empty `new_separators` array ([]) would end up in the else path of the condition below and used in a function where it is expected to be non empty. ```python if new_separators is None: ... else: # _split_text() expects this array to be non-empty! other_info = self._split_text(s, new_separators) ``` resulting in an `IndexError` ```python def _split_text(self, text: str, separators: List[str]) -> List[str]: """Split incoming text and return chunks.""" final_chunks = [] # Get appropriate separator to use > separator = separators[-1] E IndexError: list index out of range langchain/text_splitter.py:425: IndexError ``` #### Who can review? @hwchase17 @eyurtsev --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>	1 year ago

ByronHsu	9d658aaa5a	Add more code splitters (go, rst, js, java, cpp, scala, ruby, php, swift, rust) (#5171 ) As the title says, I added more code splitters. The implementation is trivial, so i don't add separate tests for each splitter. Let me know if any concerns. Fixes # (issue) https://github.com/hwchase17/langchain/issues/5170 ## Who can review?

Community members can review the PR once tests pass. Tag maintainers/contributors who might be interested: @eyurtsev In the case where documents is a generator that can only be iterated once making this change is a huge help. Otherwise a silent issue happens where metadata is empty for all documents when documents is a generator.

Roma	2b4e9a3efa	Add unit test for _merge_splits function (#3513 ) This commit adds a new unit test for the _merge_splits function in the text splitter. The new test verifies that the function merges text into chunks of the correct size and overlap, using a specified separator. The test passes on the current implementation of the function.	1 year ago
