library for LangChain documents

docculus

A python library for LangChain documents

Overview

docculus provides utilities for working with langchain_core.documents.Document objects: analyzing, transforming, hashing, validating, and displaying them.

• docculus.analysis — content/metadata statistics, duplicate and empty-document detection
• docculus.transform — filter, sort, deduplicate, truncate, assign ids, and format documents into LLM-friendly strings (XML, Markdown, JSON)
• docculus.hashing — deterministic hashing of documents (including a stable UUID variant)
• docculus.validation — consistency checks across documents sharing an id
• docculus.display — pretty-print documents and their metadata to the terminal
• docculus.utils — helpers such as fake document generation for testing

Installation

pip install docculus

Quick start

from langchain_core.documents import Document
from docculus.analysis import compute_content_stats_exact
from docculus.transform import deduplicate_documents, format_documents

docs = [
    Document(id="1", page_content="The cat sat on the mat."),
    Document(id="2", page_content="The cat sat on the mat."),
    Document(id="3", page_content="The dog chased the ball."),
]

stats = compute_content_stats_exact(docs)
print(stats["count"], stats["duplicate_count"])

unique_docs = deduplicate_documents(docs)
print(format_documents(unique_docs, output_format="markdown"))
