Action Aperture 🔍

Action Aperture is a terminal-based UI (TUI) for inspecting and analyzing GitHub Actions logs. View test results, warnings, coverage reports, and raw logs in an intuitive, keyboard-driven interface.

Features

• 📊 Intelligent Log Parsing: Automatically detects and parses different log formats
• 🧪 Pytest Support: Built-in parser for pytest logs with slowest tests, warnings, and coverage
• 🚀 Fast Navigation: Keyboard shortcuts for quick browsing through workflows, runs, and jobs
• 📋 Copy to Clipboard: Easily copy log sections for sharing or further analysis
• 🔌 Extensible: Plugin-based architecture for adding support for more log types
• 💻 GitHub CLI Integration: Uses gh CLI for seamless GitHub Actions access

Installation

Using uv (recommended)

uv tool install action-aperture

Or skip install entirely with:

uvx --from action-aperture actap

From source

gh repo clone williambdean/action-aperture
cd action-aperture
uv tool install .

Prerequisites

• GitHub CLI (gh) installed and authenticated

Usage

Basic Usage

Launch the TUI in the current repository:

actap

Specify a repository:

actap owner/repo

Advanced Options

Open a specific workflow run:

actap --run-id 123456789
actap --run-url https://github.com/owner/repo/actions/runs/123456789

Pre-select a specific job:

actap --run-id 123456789 --job-id 987654321

Environment Variables

Set a default repository with the APERTURE_REPO environment variable:

export APERTURE_REPO=owner/repo
actap

Keyboard Shortcuts

Navigation

• j/k or ↑/↓: Navigate jobs
• ←/→: Switch between log sections
• t/T: Cycle through sections forward/backward
• u/d: Page up/down in logs
• Enter: Refresh current job

Views

• F: Toggle fullscreen detail view
• c: Copy current log section to clipboard

General

• r: Refresh jobs list
• Esc: Go back / Exit

Supported Log Parsers

Pytest (Built-in)

Automatically detects pytest test logs and extracts:

• Slowest Tests: Duration analysis for optimization
• Warnings: Summary of all warnings
• Coverage: Test coverage reports
• Raw Logs: Full unprocessed output

Future Parsers

Action Aperture is designed to support multiple log formats. Planned additions include:

• ESLint/Prettier logs
• TypeScript compiler output
• Ruff/mypy linting results
• Release logs
• Custom workflow logs

Contributing

We welcome contributions! To add a new log parser:

1. Create a new parser class in src/aperture/parsers/
2. Inherit from LogParser base class
3. Implement detection and parsing logic
4. Register in src/aperture/parsers/__init__.py

See src/aperture/parsers/pytest.py for a complete example.
