A Python tool for splitting large Markdown files into smaller sections based on a specified token limit. This is particularly useful for processing large Markdown files with GPT models, as it allows the models to handle the data in manageable chunks.

Project description

split_markdown4gpt

split_markdown4gpt is a Python tool designed to split large Markdown files into smaller sections based on a specified token limit. This is particularly useful for processing large Markdown files with GPT models, as it allows the models to handle the data in manageable chunks.

Version 1.0.1 (2023-06-18)

Installation

You can install split_markdown4gpt via pip:

pip install split_markdown4gpt

CLI usage

After installation, you can use the mdsplit4gpt command to split a Markdown file. Here's the basic syntax:

mdsplit4gpt path_to_your_file.md --model gpt-3.5-turbo --limit 4096 --separator "=== SPLIT ==="

This command will split the Markdown file at path_to_your_file.md into sections, each containing no more than 4096 tokens (as counted by the gpt-3.5-turbo model). The sections will be separated by === SPLIT ===.

All CLI options:

NAME
    mdsplit4gpt

SYNOPSIS
    mdsplit4gpt MD_PATH <flags>

POSITIONAL ARGUMENTS
    MD_PATH
        Type: Union

FLAGS
    -m, --model=MODEL
        Type: str
        Default: 'gpt-3.5-turbo'
    -l, --limit=LIMIT
        Type: Optional[int]
        Default: None
    -s, --separator=SEPARATOR
        Type: str
        Default: '=== SPLIT ==='

Python usage

You can also use split_markdown4gpt in your Python code. Here's a basic example:

from split_markdown4gpt import split

sections = split("path_to_your_file.md", model="gpt-3.5-turbo", limit=4096)
for section in sections:
    print(section)

This code does the same thing as the CLI command above, but in Python.

How it works

split_markdown4gpt works by tokenizing the input Markdown file using the specified GPT model's tokenizer (default is gpt-3.5-turbo). It then splits the file into sections, each containing no more than the specified token limit.

The splitting process respects the structure of the Markdown file. It will not split a section (as defined by Markdown headings) across multiple output sections unless the section is longer than the token limit. In that case, it will split the section at the sentence level.

The tool uses several libraries to accomplish this:

  • tiktoken for tokenizing the text according to the GPT model's rules.
  • fire for creating the CLI.
  • frontmatter for parsing the Markdown file's front matter (metadata at the start of the file).
  • mistletoe for parsing the Markdown file into a syntax tree.
  • syntok for splitting the text into sentences.
  • regex and PyYAML for various utility functions.
