Max Mulatz	058a64c563	Community[minor]: Add language parser for Elixir (#22742 ) Hi 👋 First off, thanks a ton for your work on this 💚 Really appreciate what you're providing here for the community. ## Description This PR adds a basic language parser for the [Elixir](https://elixir-lang.org/) programming language. The parser code is based upon the approach outlined in https://github.com/langchain-ai/langchain/pull/13318: it's using `tree-sitter` under the hood and aligns with all the other `tree-sitter` based parses added that PR. The `CHUNK_QUERY` I'm using here is probably not the most sophisticated one, but it worked for my application. It's a starting point to provide "core" parsing support for Elixir in LangChain. It enables people to use the language parser out in real world applications which may then lead to further tweaking of the queries. I consider this PR just the ground work. - Dependencies: requires `tree-sitter` and `tree-sitter-languages` from the extended dependencies - Twitter handle:`@bitcrowd` ## Checklist - [x] PR title: "package: description" - [x] Add tests and docs - [x] Lint and test: Run `make format`, `make lint` and `make test` from the root of the package(s) you've modified. <!-- If no one reviews your PR within a few days, please @-mention one of baskaryan, efriis, eyurtsev, ccurme, vbarda, hwchase17. -->	3 months ago
Philippe PRADOS	2d4689d721	langchain[minor]: Add pgvector to list of supported vectorstores in self query retriever (#22678 ) The fact that we outsourced pgvector to another project has an unintended effect. The mapping dictionary found by `_get_builtin_translator()` cannot recognize the new version of pgvector because it comes from another package. `SelfQueryRetriever` no longer knows `PGVector`. I propose to fix this by creating a global dictionary that can be populated by various database implementations. Thus, importing `langchain_postgres` will allow the registration of the `PGvector` mapping. But for the moment I'm just adding a lazy import Furthermore, the implementation of _get_builtin_translator() reconstructs the BUILTIN_TRANSLATORS variable with each invocation, which is not very efficient. A global map would be an optimization. - Twitter handle: pprados @eyurtsev, can you review this PR? And unlock the PR [Add async mode for pgvector](https://github.com/langchain-ai/langchain-postgres/pull/32) and PR [community[minor]: Add SQL storage implementation](https://github.com/langchain-ai/langchain/pull/22207)?

Enzo Poggio	8f019e91d7	community[patch]: Use Custom Logger Instead of Root Logger in get_user_agent Function (#22691 ) ## Description This PR addresses a logging inconsistency in the `get_user_agent` function. Previously, the function was using the root logger to log a warning message when the "USER_AGENT" environment variable was not set. This bypassed the custom logger `log` that was created at the start of the module, leading to potential inconsistencies in logging behavior. Changes: - Replaced `logging.warning` with `log.warning` in the `get_user_agent` function to ensure that the custom logger is used. This change ensures that all logging in the `get_user_agent` function respects the configurations of the custom logger, leading to more consistent and predictable logging behavior. ## Dependencies None ## Issue None ## Tests and docs ☝🏻 see description ## `make format`, `make lint` & `cd libs/community; make test` ```shell > make format poetry run ruff format docs templates cookbook 1417 files left unchanged poetry run ruff check --select I --fix docs templates cookbook All checks passed! ``` ```shell > make lint poetry run ruff check docs templates cookbook All checks passed! poetry run ruff format docs templates cookbook --diff 1417 files already formatted poetry run ruff check --select I docs templates cookbook All checks passed! git grep 'from langchain import' docs/docs templates cookbook \| grep -vE 'from langchain import (hub)' && exit 1 \|\| exit 0 ``` ~cd libs/community; make test~ too much dependencies for integration ... ```shell > poetry run pytest tests/unit_tests .... ==== 884 passed, 466 skipped, 4447 warnings in 15.93s ==== ``` I choose you randomly : @ccurme	3 months ago
