Install it if refgenie or a tool depending on refgenconf is part of your workflow.
Refgenie manages standardized folder structures and indexes for reference genome files, automating organization and retrieval of genomic resources for bioinformatics workflows.
Install it if you work with multiple genomes or need to share genome resources across a team or pipeline.
Reflex is a Python framework for building full-stack web applications with frontend and backend entirely in Python, then deploying them as interactive web services.
Provides core type definitions and shared utilities for the Reflex framework.
Provides reusable code display components for Reflex web applications, enabling developers to render syntax-highlighted code blocks in their UIs.
Provides a collection of UI components for building web interfaces with Reflex, a Python framework for reactive web applications.
Provides data table editing components for Reflex web applications, enabling interactive grid-based data manipulation within the Reflex framework.
Provides Reflex components for integrating Grid.js, a JavaScript data table library, into Reflex web applications.
Provides Lucide icon components for Reflex web applications, allowing developers to use a library of vector icons in their UI.
Provides Reflex components for rendering and displaying markdown content in web applications built with the Reflex framework.
Install only if you are already committed to the Reflex framework and need markdown display capabilities.
Provides Reflex UI components for moment-based date and time handling within Reflex web applications.
Provides Plotly chart and graph components for the Reflex web framework, enabling interactive data visualization in Reflex applications.
Provides Radix UI component bindings for Reflex, enabling developers to build web interfaces using Radix's accessible, unstyled component library within Reflex applications.
Provides Reflex components that wrap the react-player library, enabling video and audio playback in Reflex web applications.
Provides Recharts charting components for use within Reflex web applications, enabling interactive data visualization in Python-based UIs.
Provides Reflex components for Sonner toast notifications, enabling developers to display dismissible notification messages in web applications built with Reflex.
Install only if you are already committed to the Reflex framework.
A command-line tool for managing Reflex application hosting and deployment operations.
Automatically formats Gherkin feature files to enforce consistent style and indentation, available as a command-line tool or pre-commit hook.
Refurb is a static analysis tool that scans Python code to identify modernization opportunities and suggest idiomatic rewrites, powered by mypy for type checking.
A drop-in replacement for Python's standard `re` module that adds advanced regex features like nested sets, fuzzy matching, lookaround in conditionals, and full Unicode case-folding while maintaining backward compatibility.
Regexploit analyzes regular expressions to identify those vulnerable to Regular Expression Denial of Service (ReDoS) attacks and generates example malicious input strings that trigger catastrophic backtracking.
However, maintenance is dormant (last release March 2021), so treat it as a stable utility rather than an actively developed project.
regionmask creates spatial masks for gridded data that identify which region each grid point belongs to, enabling regional aggregation of climate, reanalysis, and other geospatial datasets.
Install it if you work with gridded data and need to aggregate or mask by geographic region.
Regions provides tools for defining, manipulating, and analyzing astronomical regions—geometric shapes on the sky used in astronomy data analysis.
regopy wraps the Open Policy Agent's Rego language compiler and runtime, letting you write and execute Rego policy queries directly from Python code.
Provides Python bindings to the Rust regress crate for ECMA-compliant regular expression matching, offering an alternative regex engine to Python's built-in re module.
However, the aging maintenance status and Beta classification mean you should verify that ECMA regex behavior is actually required for your use case—Python's built-in…
Provides a Python client library for accessing the Reka API, with support for synchronous and asynchronous chat operations, multimodal content, and streaming responses.
However, the 683-day maintenance gap raises a red flag: verify that Reka's API service is still actively supported and that this SDK will receive updates if the API…
rel is a cross-platform asynchronous event dispatcher that selects from available system notification methods (epoll, kqueue, poll, select, pyevent) to handle network events efficiently.
However, verify first whether its API and performance characteristics match your use case—asyncio or other modern frameworks may be more suitable for new projects.
Automatically creates and optionally pushes semantic version git tags following SemVer rules, with support for major/minor/patch increments and pre-release versions.
Relenv builds self-contained, reproducible Python interpreters from source that can be relocated across filesystems and machines of the same architecture, bundling the entire Python runtime rather than just packages.
However, verify the license status before use, and confirm that the compilation overhead and disk footprint of self-contained builds fit your use case—this is not a…
Reliability engineering and survival analysis library that fits probability distributions to data, models failure mechanisms, and provides tools for accelerated life testing and repairable systems analysis.
Removes image backgrounds using deep learning models, available as a Python library, CLI tool, HTTP server, or Docker container.
ReMe is a local-first knowledge base that converts conversations and resources into searchable, interconnected Markdown files with wikilinks, designed to give AI agents and users a persistent, editable memory layer.
Exposes Python's debugger (pdb) over a TCP socket so you can connect remotely via telnet or netcat to debug a running process without stopping it.
Download individual files from remote zip archives without fetching the entire file, using HTTP range requests to minimize bandwidth.
Reads and extracts files from ZIP archives hosted on remote servers without downloading the entire archive, using HTTP range requests to fetch only the needed portions.
Communicates with Renault's private API to read vehicle attributes like mileage, GPS location, battery/fuel autonomy, and manage HVAC and charge schedules for supported vehicles.
Official Python SDK for Render that lets you define and run workflow tasks, manage task runs, and access experimental features like object storage and key-value services.
Rendercanvas provides a unified canvas API that works across multiple GUI backends, letting you write rendering code once and deploy it to different windowing systems.
RenderCV converts a YAML resume file into a professionally typeset PDF with multiple design themes, handling layout, typography, and formatting automatically.
