OneFileLLM is a command-line tool designed to streamline the creation of information-dense prompts for large language models (LLMs). It aggregates and preprocesses data from a variety of sources, compiling them into a single text file that is automatically copied to your clipboard for quick use.

• Automatic source type detection based on provided path, URL, or identifier
• Support for local files and/or directories, GitHub repositories, GitHub pull requests, GitHub issues, academic papers from ArXiv, YouTube transcripts, web page documentation, Sci-Hub hosted papers via DOI or PMID
• Handling of multiple file formats, including Jupyter Notebooks (.ipynb), PDFs, and Excel files (.xls/.xlsx)
• Advanced asynchronous web crawling with extensive configuration options for depth, concurrency, content filtering, and robots.txt compliance
• Integration with Sci-Hub for automatic downloading of research papers using DOIs or PMIDs
• Text preprocessing, including compressed and uncompressed outputs, stopword removal, and lowercase conversion
• Automatic copying of uncompressed text to the clipboard for easy pasting into LLMs
• Token count reporting for both compressed and uncompressed outputs
• XML encapsulation of output for improved LLM performance
• Text stream input processing directly from stdin or clipboard
• Format detection and processing for plain text, Markdown, JSON, HTML, and YAML
• Format override option to control input processing
• Excel spreadsheet (.xls/.xlsx) processing to Markdown tables
• Alias system for frequently used sources
• Proper PDF text extraction from local files
• Cross-platform launcher scripts for easy execution

Install the required dependencies:

pip install -U -r requirements.txt

To access private GitHub repositories, generate a personal access token as described in the 'Obtaining a GitHub Personal Access Token' section here:

Obtaining a GitHub Personal Access Token

Clone the repository or download the source code.

Run the script using the following command:

python onefilellm.py

You can pass a single URL or path as a command line argument for faster processing:

python onefilellm.py https://github.com/jimmc414/1filellm

OneFileLLM now supports processing text directly from standard input (stdin) or the system clipboard:

Use the - argument to process text from standard input:

# Process text from a file via pipe
cat README.md | python onefilellm.py -

# Process output from another command
git diff | python onefilellm.py -

Use the --clipboard or -c argument to process text from the system clipboard:

# Copy text to clipboard first, then run:
python onefilellm.py --clipboard

# Or using the short form:
python onefilellm.py -c

OneFileLLM automatically detects the format of input text (plain text, Markdown, JSON, HTML, YAML) and processes it accordingly. You can override this detection with the --format or -f option:

# Force processing as JSON
cat data.txt | python onefilellm.py - --format json

# Force processing clipboard content as Markdown 
python onefilellm.py --clipboard -f markdown

Supported format types: text, markdown, json, html, yaml, doculing, markitdown

OneFileLLM supports processing multiple inputs at once. Simply provide multiple paths or URLs as command line arguments:

python onefilellm.py https://github.com/jimmc414/1filellm test_file1.txt test_file2.txt

When multiple inputs are provided, OneFileLLM will:

1. Process each input separately according to its type
2. Combine all outputs into a single XML document with the <onefilellm_output> root tag
3. Save the combined output to output.xml
4. Copy the content to your clipboard for immediate use with LLMs

OneFileLLM includes a powerful alias system that allows you to create shortcuts for frequently used commands with support for placeholders and advanced management:

Create, list, and remove aliases using the new alias management commands:

# Add or update an alias
python onefilellm.py --alias-add myrepo "https://github.com/user/repo"

# Add alias with flags and options
python onefilellm.py --alias-add deepcrawl "https://docs.example.com --crawl-max-depth 4 --crawl-include-pattern '/docs/'"

# List all aliases (core and user-defined)
python onefilellm.py --alias-list

# List only pre-shipped core aliases
python onefilellm.py --alias-list-core

# Remove a user-defined alias
python onefilellm.py --alias-remove myrepo

Aliases support a {} placeholder that gets replaced with your input:

# Create alias with placeholder
python onefilellm.py --alias-add github_search "https://github.com/search?q={}"

# Use with replacement value
python onefilellm.py github_search "onefilellm"
# Expands to: https://github.com/search?q=onefilellm

# Create complex alias with multiple flags
python onefilellm.py --alias-add crawl_site "{} --crawl-max-depth 3 --crawl-respect-robots"

# Use it
python onefilellm.py crawl_site "https://docs.python.org"
# Expands to: https://docs.python.org --crawl-max-depth 3 --crawl-respect-robots

OneFileLLM comes with useful pre-shipped aliases:

• ofl_repo - OneFileLLM GitHub repository
• ofl_readme - OneFileLLM README file
• gh_search - GitHub search with placeholder: https://github.com/search?q={}
• arxiv_search - ArXiv search with placeholder

• User aliases override core aliases with the same name
• JSON storage: User aliases stored in ~/.onefilellm_aliases/aliases.json
• Robust error handling: Graceful handling of missing or corrupted alias files
• Validation: Alias names must be alphanumeric with optional hyphens/underscores

Use aliases just like any other input:

# Use a simple alias
python onefilellm.py ofl_repo

# Use alias with placeholder
python onefilellm.py gh_search "python"

# Mix aliases with direct inputs
python onefilellm.py ofl_repo local_file.txt

# Combine multiple aliases and arguments
python onefilellm.py ofl_repo github_search "machine learning" --format markdown

OneFileLLM features a powerful asynchronous web crawler with extensive configuration options for precise control over content extraction:

# Basic web crawl (default: 3 levels deep, up to 1000 pages)
python onefilellm.py https://docs.example.com

# Custom depth and page limits

12. Clipboard

    • Example Input: python onefilellm.py --clipboard
    • Output: The clipboard text content is processed according to its detected format (or format override).

The script generates the following output files:

• output.xml: The full XML-structured output, automatically copied to the clipboard.
• compressed_output.txt: Cleaned and compressed text (when NLTK processing is enabled).
• processed_urls.txt: A list of all processed URLs during web crawling.

To modify the allowed file types for repository processing, update the allowed_extensions list in the code:

allowed_extensions = ['.py', '.txt', '.js', '.rst', '.sh', '.md', '.pyx', '.html', '.yaml','.json', '.jsonl', '.ipynb', '.h', '.c', '.sql', '.csv']

Web crawling behavior is now controlled through command-line arguments rather than hardcoded values. You can configure:

• Crawl depth: Use --crawl-max-depth N (default: 3)
• Page limits: Use --crawl-max-pages N (default: 1000)
• URL filtering: Use --crawl-include-pattern and --crawl-exclude-pattern
• Content processing: Use flags like --crawl-include-images, --crawl-no-include-code
• Request behavior: Use --crawl-delay, --crawl-timeout, --crawl-concurrency
• Domain restrictions: Use --crawl-follow-links, --crawl-restrict-path
• Robots.txt compliance: Use --crawl-respect-robots

The tool supports environment variables for configuration:

• GITHUB_TOKEN: Set your GitHub personal access token for private repository access
• RUN_INTEGRATION_TESTS: Set to true to enable integration tests
• RUN_SLOW_TESTS: Set to true to enable slow tests

You can also use a .env file in the project root directory to set these variables:

# .env file
GITHUB_TOKEN=your_github_token_here
RUN_INTEGRATION_TESTS=false
RUN_SLOW_TESTS=false

To access private GitHub repositories, you need a personal access token. Follow these steps:

1. Log in to your GitHub account and go to Settings.
2. Navigate to Developer settings > Personal access tokens.
3. Click on "Generate new token" and provide a name.
4. Select the necessary scopes (at least repo for private repositories).
5. Click "Generate token" and copy the token value.

In the onefilellm.py script, replace GITHUB_TOKEN with your actual token or set it as an environment variable:

• For Windows:

  setx GITHUB_TOKEN "YourGitHubToken"

• For Linux:

  echo 'export GITHUB_TOKEN="YourGitHubToken"' >> ~/.bashrc
  source ~/.bashrc

All output is encapsulated in XML tags. This structure was implemented based on evaluations showing that LLMs perform better with prompts structured in XML. The general structure of the output is as follows:

<onefilellm_output>
  <source type="[source_type]" [additional_attributes]>
    <[content_type]>
      [Extracted content]
    </[content_type]>
  </source>
</onefilellm_output>

<onefilellm_output>
  <source type="[source_type_1]" [additional_attributes]>
    <[content_type]>
      [Extracted content 1]
    </[content_type]>
  </source>
  <source type="[source_type_2]" [additional_attributes]>
    <[content_type]>
      [Extracted content 2]
    </[content_type]>
  </source>
  <!-- Additional sources as needed -->
</onefilellm_output>

Where [source_type] could be one of: "github_repository", "github_pull_request", "github_issue", "arxiv_paper", "youtube_transcript", "web_documentation", "sci_hub_paper", "local_directory", "local_file", "stdin", or "clipboard".

This XML structure provides clear delineation of different content types and sources, improving the LLM's understanding and processing of the input.
