📄 Description

Implements a configurable pipeline for transforming document content during the loading process.

Changes:
Added support for document function type in the plugin system Created prioritized processing pipeline for document content Added robust validation and error handling for processor functions Included sample document processor that removes common artifacts from imported documents

Document processors can be created as standard plugins and will be applied to all loaded documents when active. Processing order is determined by the priority valve setting.

Sample document processor:

import re
import logging
from pydantic import BaseModel, Field

from open_webui.env import SRC_LOG_LEVELS

log = logging.getLogger(__name__)
log.setLevel(SRC_LOG_LEVELS["MAIN"])

class Document:
    """
    Document cleaner that removes common artifacts from imported documents.

    This processor cleans up document text by removing:
    - Document banners (CONFIDENTIAL, INTERNAL, DRAFT)
    - Page numbers and footers
    - Excessive whitespace and line breaks
    """

    class Valves(BaseModel):
        priority: int = Field(default=0, description="Processing priority (lower numbers run first)")

    def __init__(self):
        self.valves = self.Valves()

    def process(self, text: str) -> str:
        """
        Clean document text by removing common artifacts.

        Args:
            text: Original document text

        Returns:
            Cleaned document text
        """
        if not text or not isinstance(text, str):
            return text

        # Remove banners like "## INTERNAL ##", "**CONFIDENTIAL**", etc.
        text = re.sub(
            r"^\s*[#*\-]*\s*(internal|confidential|draft)\s*[#*\-]*\s*$",
            "",
            text,
            flags=re.IGNORECASE | re.MULTILINE,
        )

        # Remove footers like "page 3 of 10"
        text = re.sub(r"page\s*\d+\s*of\s*\d+", "", text, flags=re.IGNORECASE)

        # Collapse excessive empty lines
        text = re.sub(r"\n\s*\n+", "\n\n", text)

        return text.strip()
