community[patch]: Allow override of 'fetch_schema_from_transport' in the GraphQL tool (#17649)
- **Description:** In order to override the bool value of
"fetch_schema_from_transport" in the GraphQLAPIWrapper, a
"fetch_schema_from_transport" value needed to be added to the
"_EXTRA_OPTIONAL_TOOLS" dictionary in load_tools in the "graphql" key.
The parameter "fetch_schema_from_transport" must also be passed in to
the GraphQLAPIWrapper to allow reading of the value when creating the
client. Passing as an optional parameter is probably best to avoid
breaking changes. This change is necessary to support GraphQL instances
that do not support fetching schema, such as TigerGraph. More info here:
[TigerGraph GraphQL Schema
Docs](https://docs.tigergraph.com/graphql/current/schema)

community[minor]: Adds Llamafile as an LLM (#17431)
* **Description:** Adds a simple LLM implementation for interacting with
[llamafile](https://github.com/Mozilla-Ocho/llamafile)-based models.
* **Dependencies:** N/A
* **Issue:** N/A

**Detail**
[llamafile](https://github.com/Mozilla-Ocho/llamafile) lets you run LLMs
locally from a single file on most computers without installing any
dependencies.

To use the llamafile LLM implementation, the user needs to:

1. Download a llamafile e.g.
https://huggingface.co/jartine/TinyLlama-1.1B-Chat-v1.0-GGUF/resolve/main/TinyLlama-1.1B-Chat-v1.0.Q5_K_M.llamafile?download=true
2. Make the file executable.
3. Run the llamafile in 'server mode'. (All llamafiles come packaged
with a lightweight server; by default, the server listens at
`http://localhost:8080`.)


```bash
wget https://url/of/model.llamafile
chmod +x model.llamafile
./model.llamafile --server --nobrowser
```

Now, the user can invoke the LLM via the LangChain client:

```python
from langchain_community.llms.llamafile import Llamafile

llm = Llamafile()

llm.invoke("Tell me a joke.")
```

                                collection_name="test-collection")

# Set values for keys
doc1 = Document(page_content='test1')
doc2 = Document(page_content='test2')
mongodb_store.mset([("key1", doc1), ("key2", doc2)])

# Get values for keys
values = mongodb_store.mget(["key1", "key2"])
# [doc1, doc2]

# Iterate over keys
for key in mongodb_store.yield_keys():
    print(key)

# Delete keys
mongodb_store.mdelete(["key1", "key2"])
 ```

  - **Dependencies:**
  Use `mongomock` for integration test.

Framework for supporting more languages in LanguageParser (#13318)
## Description

I am submitting this for a school project as part of a team of 5. Other
team members are @LeilaChr, @maazh10, @Megabear137, @jelalalamy. This PR
also has contributions from community members @Harrolee and @Mario928.

Initial context is in the issue we opened (#11229).

This pull request adds:

- Generic framework for expanding the languages that `LanguageParser`
can handle, using the
[tree-sitter](https://github.com/tree-sitter/py-tree-sitter#py-tree-sitter)
parsing library and existing language-specific parsers written for it
- Support for the following additional languages in `LanguageParser`:
  - C
  - C++
  - C#
  - Go
- Java (contributed by @Mario928
https://github.com/ThatsJustCheesy/langchain/pull/2)
  - Kotlin
  - Lua
  - Perl
  - Ruby
  - Rust
  - Scala
- TypeScript (contributed by @Harrolee
https://github.com/ThatsJustCheesy/langchain/pull/1)

Here is the [design
document](https://docs.google.com/document/d/17dB14cKCWAaiTeSeBtxHpoVPGKrsPye8W0o_WClz2kk)
if curious, but no need to read it.

## Issues

- Closes #11229
- Closes #10996
- Closes #8405

## Dependencies

`tree_sitter` and `tree_sitter_languages` on PyPI. We have tried to add
these as optional dependencies.

## Documentation

We have updated the list of supported languages, and also added a
section to `source_code.ipynb` detailing how to add support for
additional languages using our framework.

## Maintainer

- @hwchase17 (previously reviewed
https://github.com/langchain-ai/langchain/pull/6486)

Thanks!!

## Git commits

We will gladly squash any/all of our commits (esp merge commits) if
necessary. Let us know if this is desirable, or if you will be
squash-merging anyway.

community[minor], langchian[minor]: Add Neptune Rdf graph and chain (#16650)
**Description**: This PR adds a chain for Amazon Neptune graph database
RDF format. It complements the existing Neptune Cypher chain. The PR
also includes a Neptune RDF graph class to connect to, introspect, and
query a Neptune RDF graph database from the chain. A sample notebook is
provided under docs that demonstrates the overall effect: invoking the
chain to make natural language queries against Neptune using an LLM.

**Issue**: This is a new feature
 
**Dependencies**: The RDF graph class depends on the AWS boto3 library
if using IAM authentication to connect to the Neptune database.

community[patch]: Support SerDe transform functions in Databricks LLM (#16752)
**Description:** Databricks LLM does not support SerDe the
transform_input_fn and transform_output_fn. After saving and loading,
the LLM will be broken. This PR serialize these functions into a hex
string using pickle, and saving the hex string in the yaml file. Using
pickle to serialize a function can be flaky, but this is a simple
workaround that unblocks many use cases. If more sophisticated SerDe is
needed, we can improve it later.

Test:
Added a simple unit test.
I did manual test on Databricks and it works well.
The saved yaml looks like:
```
llm:
      _type: databricks
      cluster_driver_port: null
      cluster_id: null

community[minor]: add github file loader to load any github file content b… (#15305)
### Description
support load any github file content based on file extension.  

Why not use [git
loader](https://python.langchain.com/docs/integrations/document_loaders/git#load-existing-repository-from-disk)
?
git loader clones the whole repo even only interested part of files,
that's too heavy. This GithubFileLoader only downloads that you are
interested files.

community: Added new Utility runnables for NVIDIA Riva. (#15966)
**Please tag this issue with `nvidia_genai`**

- **Description:** Added new Runnables for integration NVIDIA Riva into
LCEL chains for Automatic Speech Recognition (ASR) and Text To Speech
(TTS).
- **Issue:** N/A
- **Dependencies:** To use these runnables, the NVIDIA Riva client
libraries are required. It they are not installed, an error will be
raised instructing how to install them. The Runnables can be safely
imported without the riva client libraries.
- **Twitter handle:** N/A

All of the Riva Runnables are inside a single folder in the Utilities
module. In this folder are four files:
- common.py - Contains all code that is common to both TTS and ASR
- stream.py - Contains a class representing an audio stream that allows
the end user to put data into the stream like a queue.
- asr.py - Contains the RivaASR runnable
- tts.py - Contains the RivaTTS runnable

The following Python function is an example of creating a chain that
makes use of both of these Runnables:

```python
def create(
    config: Configuration,
    audio_encoding: RivaAudioEncoding,
    sample_rate: int,
    audio_channels: int = 1,
) -> Runnable[ASRInputType, TTSOutputType]:
    """Create a new instance of the chain."""
    _LOGGER.info("Instantiating the chain.")

    # create the riva asr client
    riva_asr = RivaASR(
        url=str(config.riva_asr.service.url),
        ssl_cert=config.riva_asr.service.ssl_cert,
        encoding=audio_encoding,
        audio_channel_count=audio_channels,
        sample_rate_hertz=sample_rate,
        profanity_filter=config.riva_asr.profanity_filter,
        enable_automatic_punctuation=config.riva_asr.enable_automatic_punctuation,
        language_code=config.riva_asr.language_code,
    )

    # create the prompt template
    prompt = PromptTemplate.from_template("{user_input}")

    # model = ChatOpenAI()
    model = ChatNVIDIA(model="mixtral_8x7b")  # type: ignore

    # create the riva tts client
    riva_tts = RivaTTS(
        url=str(config.riva_asr.service.url),
        ssl_cert=config.riva_asr.service.ssl_cert,
        output_directory=config.riva_tts.output_directory,
        language_code=config.riva_tts.language_code,
        voice_name=config.riva_tts.voice_name,
    )

    # construct and return the chain
    return {"user_input": riva_asr} | prompt | model | riva_tts  # type: ignore
```

The following code is an example of creating a new audio stream for
Riva:

```python
input_stream = AudioStream(maxsize=1000)
# Send bytes into the stream
for chunk in audio_chunks:
    await input_stream.aput(chunk)
input_stream.close()
```

The following code is an example of how to execute the chain with
RivaASR and RivaTTS

```python
output_stream = asyncio.Queue()
while not input_stream.complete:
    async for chunk in chain.astream(input_stream):
        output_stream.put(chunk)    
```

Everything should be async safe and thread safe. Audio data can be put
into the input stream while the chain is running without interruptions.

community: add support for callable filters in FAISS (#16190)
- **Description:**
Filtering in a FAISS vectorstores is very inflexible and doesn't allow
that many use case. I think supporting callable like this enables a lot:
regular expressions, condition on multiple keys etc. **Note** I had to
manually alter a test. I don't understand if it was falty to begin with
or if there is something funky going on.

community[patch]: Milvus supports add & delete texts by ids (#16256)
# Description

To support [langchain
indexing](https://python.langchain.com/docs/modules/data_connection/indexing)
as requested by users, vectorstore Milvus needs to support:
- document addition by id (`add_documents` method with `ids` argument)
- delete by id (`delete` method with `ids` argument)

Example usage:

```python
from langchain.indexes import SQLRecordManager, index
from langchain.schema import Document
from langchain_community.vectorstores import Milvus
from langchain_openai import OpenAIEmbeddings

collection_name = "test_index"
embedding = OpenAIEmbeddings()
vectorstore = Milvus(embedding_function=embedding, collection_name=collection_name)

namespace = f"milvus/{collection_name}"
record_manager = SQLRecordManager(
    namespace, db_url="sqlite:///record_manager_cache.sql"
)
record_manager.create_schema()

doc1 = Document(page_content="kitty", metadata={"source": "kitty.txt"})
doc2 = Document(page_content="doggy", metadata={"source": "doggy.txt"})

index(
    [doc1, doc1, doc2],
    record_manager,
    vectorstore,
    cleanup="incremental",  # None, "incremental", or "full"
    source_id_key="source",
)
```
