octopolars 0.1.2

Pull, filter, and walk a GitHub user's repositories with Polars.

octopolars

Pull, filter, and walk a GitHub user's repositories with Polars.

Installation

pip install octopolars

The polars dependency is required but not included in the package by default. It is shipped as an optional extra which can be activated by passing it in square brackets:

pip install octopolars[polars]

If you need compatibility with older CPUs, install:

pip install octopolars[polars-lts-cpu]

Features

• GitHub repo enumeration: Retrieve user’s public repos (caching results to speed up repeated calls).
• Apply filters: Use either raw Polars expressions or a shorthand DSL (e.g. {name}.str.starts_with("foo")) to filter repos.
• File tree walking: Enumerate all files in each repository using fsspec[github], supporting recursion and optional size filters.
• Output formats: Display data in a Polars repr table (which can be read back in) or export to CSV/JSON/NDJSON.
• Control table size: Limit the number of rows or columns displayed, or use --short mode to quickly preview data.
• Caching: By default, results are cached in the user’s cache directory to avoid repeated API calls (unless you force refresh).

Requirements

• Python 3.9+
• gh GitHub CLI tool, for a PAT to avoid rate limits and enable file listings.
  • alternatively set the GITHUB_TOKEN environment variable as your GitHub token.

octopolars is supported by these tools:

• Polars for efficient data filtering and output formatting.
• PyGithub (for GitHub API access to enumerate the repos)
• fsspec within Universal Pathlib which provides a github:// protocol that enables enumerating files in GitHub repos as if they were local file paths.

Usage

Command-Line Interface

Usage: octopols [OPTIONS] USERNAME

  octopols - A CLI for listing GitHub repos or files by username, with
  optional recursion, table formatting, and Polars-based filtering.

    By default, rows and cols are unlimited (-1). Use --short/-s to switch to
    a minimal view.

    The --filter/-f flag (if provided) applies a Polars expression or DSL
    expression   (e.g., '{name}.str.startswith("a")') to the DataFrame of
    items.

    Examples:

      octopols lmmx

      octopols lmmx -f '{name}.str.startswith("a")'

      octopols lmmx -w --filter='pl.col("filename").str.contains("test")'

Options:
  -F, --files               List files (default lists repos).
  -R, --recursive           Recursively list items (repos or files).
  -o, --output-format TEXT  Output format: table, csv, json, or ndjson.
  -r, --rows INTEGER        Number of table rows to show. Default -1 means
                            show all.
  -c, --cols INTEGER        Number of table columns to show. Default -1 means
                            show all.
  -s, --short               Short mode: overrides --rows and --cols by setting
                            both to None.
  -f, --filter TEXT         A Polars expression or a shorthand DSL expression.
                            In the DSL, use {column} to refer to
                            pl.col('column'), e.g.
                            '{name}.str.startswith("a")'
  --help                    Show this message and exit.

Example 1: List All Repos for a User

octopols lmmx --short

Displays a table of all repositories belonging to "lmmx" in short format.

Example 4: Filter Repos by Name, List all Files

octopols lmmx -f '{name}.str.starts_with("d3") --walk'

Lists all files in every repository whose (repo) name starts with "d3" owned by "lmmx", as a table of file paths.

Library Usage

You can also import octopols.Inventory directly:

from octopols import Inventory

inv = Inventory(username="lmmx")
repos_df = inv.list_repos()

If you want to apply a filter expression programmatically and walk the file trees:

inv = Inventory(username="lmmx", repo_filter=pl.col("name").str.contains("demo"))
files_df = inv.walk_file_trees()

Project Structure

• cli.py: Defines the CLI (octopols) with all available options and flags.
• inventory.py: Core logic for retrieving repos, walking file trees, caching, and applying filters.
