octopolars 1.0.1

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

octopolars

Pull, filter, walk, and read 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]          # most users can install regular Polars
pip install octopolars[polars-lts-cpu]  # for backcompatibility with older CPUs

Requirements

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

octopolars is supported by:

• 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.

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 --quiet 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).

Usage

Command-Line Interface

Usage: octopols [OPTIONS] USERNAME

  Octopols - A CLI for listing GitHub repos or files by username, with
  filters.

  By default, this prints a table of repositories.

    The --walk/-w flag walks the files rather than just listing the repos.

    The --extract/-x flag reads all matching files (use with caution).

    The --filter/-f flag (1+ times) applies `filter` exprs, or f-string-like
    column DSL (e.g., '{name}.str.starts_with("a")').

    The --select/-s flag (1+ times) applies `select` exprs, or f-string-like
    column DSL (e.g., '{foo}.alias("bar")').

    The --addcols/-a flag (1+ times) applies `with_columns` exprs, or
    f-string-like column DSL (e.g., '{total} * 2').

    The --quiet/-q flag switches to a minimal, abridged view. By default, rows
    and cols are unlimited (-1).

  Examples
  --------

  - List all repos

      octopols lmmx

  - List all repos that start with 'd'

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

  - List only file paths from matching repos

      octopols lmmx -w --filter='{name} == "myrepo"'

  - Read the *content* of all files from matching repos

      octopols lmmx -x --filter='{name}.str.starts_with("d3")'

Options:
  -w, --walk                Walk files (default lists repos).
  -x, --extract             Read the text content of each file (not
                            directories). Use with caution on large sets!
  -o, --output-format TEXT  Output format: table, csv, json, or ndjson.
  -c, --cols INTEGER        Number of table columns to show. Default -1 means
                            show all.
  -r, --rows INTEGER        Number of table rows to show. Default -1 means
                            show all.
  -q, --quiet               Quiet mode: overrides --rows and --cols by setting
                            both to None.
  -f, --filter TEXT         One or more Polars expressions or a shorthand DSL
                            expression. In the DSL, use {column} to refer to
                            pl.col('column'), e.g.
                            '{name}.str.starts_with("a")'.
  -s, --select TEXT         One or more Polars expressions or a shorthand DSL
                            expression. In the DSL, use {column} to refer to
                            pl.col('column'), e.g. '{foo}.alias("bar")'.
  -a, --addcols TEXT        One or more Polars expressions or a shorthand DSL
                            expression. In the DSL, use {column} to refer to
                            pl.col('column'), e.g. '{total} * 2'.
  --help                    Show this message and exit.

Example 1: List All Repos for a User

Example 6: Filter Repos by Name, Add Columns Based on Description

octopols lmmx -f '{name}.str.starts_with("d3")' -a '{description}.str.contains("AWS").alias("Will It Cloud?")'

Adds a boolean column called "Will It Cloud?" based on whether the repo description contains "AWS".

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:

import polars as pl

inv = Inventory(username="lmmx", filter_exprs=[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.
