Cristóbal Carnero Liñán	e494b0a09f	feat (documents): add a source code loader based on AST manipulation (#6486 ) #### Summary A new approach to loading source code is implemented: Each top-level function and class in the code is loaded into separate documents. Then, an additional document is created with the top-level code, but without the already loaded functions and classes. This could improve the accuracy of QA chains over source code. For instance, having this script: ``` class MyClass: def __init__(self, name): self.name = name def greet(self): print(f"Hello, {self.name}!") def main(): name = input("Enter your name: ") obj = MyClass(name) obj.greet() if __name__ == '__main__': main() ``` The loader will create three documents with this content: First document: ``` class MyClass: def __init__(self, name): self.name = name def greet(self): print(f"Hello, {self.name}!") ``` Second document: ``` def main(): name = input("Enter your name: ") obj = MyClass(name) obj.greet() ``` Third document: ``` # Code for: class MyClass: # Code for: def main(): if __name__ == '__main__': main() ``` A threshold parameter is added to control whether small scripts are split in this way or not. At this moment, only Python and JavaScript are supported. The appropriate parser is determined by examining the file extension. #### Tests This PR adds: - Unit tests - Integration tests #### Dependencies Only one dependency was added as optional (needed for the JavaScript parser). #### Documentation A notebook is added showing how the loader can be used. #### Who can review? @eyurtsev @hwchase17 --------- Co-authored-by: rlm <pexpresss31@gmail.com>	1 year ago

Santiago Delgado	d84a3bcf7a	Office365 Tool (#6306 ) #### Background With the development of [structured tools](https://blog.langchain.dev/structured-tools/), the LangChain team expanded the platform's functionality to meet the needs of new applications. The GMail tool, empowered by structured tools, now supports multiple arguments and powerful search capabilities, demonstrating LangChain's ability to interact with dynamic data sources like email servers. #### Challenge The current GMail tool only supports GMail, while users often utilize other email services like Outlook in Office365. Additionally, the proposed calendar tool in PR https://github.com/hwchase17/langchain/pull/652 only works with Google Calendar, not Outlook. #### Changes This PR implements an Office365 integration for LangChain, enabling seamless email and calendar functionality with a single authentication process. #### Future Work With the core Office365 integration complete, future work could include integrating other Office365 tools such as Tasks and Address Book. #### Who can review? @hwchase17 or @vowelparrot can review this PR #### Appendix @janscas, I utilized your [O365](https://github.com/O365/python-o365) library extensively. Given the rising popularity of LangChain and similar AI frameworks, the convergence of libraries like O365 and tools like this one is likely. So, I wanted to keep you updated on our progress. --------- Co-authored-by: Dev 2049 <dev.dev2049@gmail.com>	1 year ago
Xiaochao Dong	a15afc102c	Relax the action input check for actions that require no input (#6357 ) When the tool requires no input, the LLM often gives something like this: ```json { "action": "just_do_it" } ``` I have attempted to enhance the prompt, but it doesn't appear to be functioning effectively.

Pau Ramon Revilla	87802c86d9	Added a MHTML document loader (#6311 ) MHTML is a very interesting format since it's used both for emails but also for archived webpages.

This is heavily inspired from the beautifulsoup html loader, but extracting the html part from the mhtml file. --------- Co-authored-by: rlm <pexpresss31@gmail.com>	1 year ago
