MarkItDown Sample Plugin

This project shows how to create a sample plugin for MarkItDown. The most important parts are as follows:

Next, implement your custom DocumentConverter:

from typing import BinaryIO, Any
from markitdown import MarkItDown, DocumentConverter, DocumentConverterResult, StreamInfo

class RtfConverter(DocumentConverter):

    def __init__(
        self, priority: float = DocumentConverter.PRIORITY_SPECIFIC_FILE_FORMAT
    ):
        super().__init__(priority=priority)

    def accepts(
        self,
        file_stream: BinaryIO,
        stream_info: StreamInfo,
        **kwargs: Any,
    ) -> bool:
	
	# Implement logic to check if the file stream is an RTF file
	# ...
	raise NotImplementedError()


    def convert(
        self,
        file_stream: BinaryIO,
        stream_info: StreamInfo,
        **kwargs: Any,
    ) -> DocumentConverterResult:

	# Implement logic to convert the file stream to Markdown
	# ...
	raise NotImplementedError()

Next, make sure your package implements and exports the following:

# The version of the plugin interface that this plugin uses. 
# The only supported version is 1 for now.
__plugin_interface_version__ = 1 

# The main entrypoint for the plugin. This is called each time MarkItDown instances are created.
def register_converters(markitdown: MarkItDown, **kwargs):
    """
    Called during construction of MarkItDown instances to register converters provided by plugins.
    """

    # Simply create and attach an RtfConverter instance
    markitdown.register_converter(RtfConverter())

Finally, create an entrypoint in the pyproject.toml file:

[project.entry-points."markitdown.plugin"]
sample_plugin = "markitdown_sample_plugin"

Here, the value of sample_plugin can be any key, but should ideally be the name of the plugin. The value is the fully qualified name of the package implementing the plugin.

Installation

To use the plugin with MarkItDown, it must be installed. To install the plugin from the current directory use:

pip install -e .

Once the plugin package is installed, verify that it is available to MarkItDown by running:

markitdown --list-plugins

To use the plugin for a conversion use the --use-plugins flag. For example, to convert an RTF file:

markitdown --use-plugins path-to-file.rtf

In Python, plugins can be enabled as follows:

from markitdown import MarkItDown

md = MarkItDown(enable_plugins=True) 
result = md.convert("path-to-file.rtf")
print(result.text_content)
