How do I set up yarepl.nvim for a Python REPL in Neovim?

Configure the metas in setup to include ipython, then use commands like :Yarepl start ipython or keymaps. The README provides example configurations for customizing REPLs, window settings, and project-level setups.

yarepl.nvim vs iron.nvim: which should I use?

yarepl.nvim excels in parallel sessions and flexible buffer attachments, making it better for complex workflows like mixed-language programming. Iron.nvim is simpler for basic REPL needs, so choose based on your need for multiple REPLs or AI integrations.

How can I send code from multiple buffers to a single REPL in yarepl?

Use the attach_buffer command to link buffers to a REPL, then send operations will target that REPL. The README explains how to attach and detach buffers, allowing flexible code sending across different file types.

Does yarepl.nvim work with Jupyter notebooks?

No, yarepl.nvim focuses on terminal-based REPLs and CLI apps, not Jupyter kernels. For Jupyter integration, other plugins like jupyter-vim or nvim-ipy might be more suitable.

Why is my visual selection not sending properly with yarepl send_visual?

This could be due to conflicts with plugins like which-key.nvim, as noted in the FAQ. Ensure you're using recursive mappings or disable which-key in visual mode to handle count prefixes correctly.

How to integrate Aider with yarepl.nvim?

Use the aider extension provided in yarepl, which sets up REPL metas for Aider. Refer to the extensions section in the README for setup details, including example keybindings and configuration snippets.

What is milanglacier/yarepl.nvim#aider-extensions?

yarepl.nvim is a Neovim plugin that manages REPL (Read-Eval-Print Loop) and CLI sessions within the editor. It solves the problem of rigid REPL interactions by enabling parallel sessions, flexible buffer attachments, and cross-language support, making it ideal for complex workflows like literate programming or AI-assisted coding.

Target Audience

Neovim users who frequently work with REPLs for data science, scripting, or AI coding assistants and need advanced session management beyond basic single-REPL plugins.

Value Proposition

Developers choose yarepl.nvim for its unparalleled flexibility in managing multiple REPL paradigms simultaneously, native dot-repeat support, and seamless integrations with AI tools like Aider and Codex, all without requiring external dependencies.

Overview

Versatile REPL/CLI manager. Multiple sending modes with parallel sessions, buffer attachments, and cross-language support. AI CLI integration for Aider and OpenAI Codex. Picker support, project-level configs, code cell text objects, and native dot-repeat.

Use Cases

Best For

Managing multiple concurrent REPL sessions (e.g., separate Python and R REPLs)
Sending code from a single buffer to different language REPLs in mixed-language documents
Integrating AI coding assistants like Aider or OpenAI Codex directly into Neovim workflows
Setting up project-specific REPL configurations for different development environments
Handling large code chunks by sourcing from temporary files to avoid REPL history clutter
Creating persistent REPL sessions in tmux that survive Neovim restarts

Not Ideal For

Neovim users seeking a plug-and-play REPL solution with minimal configuration effort
Projects that only require basic, single-session REPL interactions without parallel management
Teams working in environments where upgrading to Neovim 0.9 is not feasible or prioritized
Developers who prioritize graphical IDE integrations over terminal-based workflows and advanced session control

Pros & Cons

Pros

Parallel Session Management

Supports running multiple REPLs concurrently, enabling independent management for complex workflows like AI-assisted coding, as shown in the showcase with Aider and Codex.

Flexible Buffer Attachments

Allows sending code from multiple buffers to one REPL or from one buffer to multiple REPLs, ideal for mixed-language programming in documents like Rmarkdown or Quarto.

AI Tool Integration

Built-in extensions for Aider, Codex, and OpenCode seamlessly integrate AI coding assistants into Neovim, enhancing productivity for AI-driven development.

Native Dot-Repeat Support

Operators for sending and sourcing code are dot-repeatable without needing plugins like vim-repeat, simplifying repetitive tasks as highlighted in the commands section.

Cons

Steep Configuration Learning Curve

Requires extensive setup with custom keymaps and options, and the README admits no default keybindings, making initial adoption daunting for new users.

Security Risks in Source Operations

The source syntax feature uses temporary files, which the README warns could expose vulnerabilities if not handled properly, posing potential security trade-offs.

Breaking Changes and Instability

Recent breaking change from uppercase to lowercase <Plug> mappings indicates potential instability, and legacy support is limited until 2026, requiring user updates.
