SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill addresses the challenge of iterative code development by providing an interactive eval loop, facilitating quick feedback and adjustments during the coding process.

Core Features & Use Cases

  • Interactive Evaluation: Offers an immediate evaluation of code snippets, allowing developers to test and refine their code incrementally.
  • Language-Specific Hosts: Supports various language-specific hosts like nREPL for Clojure and IEx for Elixir, with a fast inner cycle for C and Zig.
  • Native Edge Support: Allows live redefinition of native functions, enabling developers to tweak and re-evaluate code without a separate build step.
  • TDD Composition: Facilitates Test-Driven Development by allowing developers to quickly iterate on tests and implementations within the loop.
  • Use Case: A developer can use this Skill to rapidly test and refine a function within a Clojure project, ensuring it meets the desired specifications before integrating it into the main codebase.

Quick Start

Start the interactive eval loop for your project by running the command 'eval' in your editor.

Frequently Asked Questions about develop-at-repl

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up an interactive eval loop for incremental code development?▼

To start interactive code evaluation for incremental development, run the 'eval' command in your editor. This initiates the eval loop, allowing you to immediately test and refine code snippets without a separate build step.

Can I use Test-Driven Development workflows with an interactive eval loop?▼

Yes, the interactive eval loop supports Test-Driven Development by letting you quickly iterate on tests and implementations within the loop. You can rapidly test and refine functions to ensure they meet specifications before integration.

Does interactive code evaluation work with Clojure and Elixir environments?▼

Interactive code evaluation works with Clojure and Elixir by utilizing language-specific hosts like nREPL and IEx. It also supports a fast inner cycle for C and Zig, enabling live redefinition of native functions.

What programming languages support live redefinition of native functions during code evaluation?▼

Live redefinition of native functions during code evaluation is supported for C and Zig through a fast inner cycle, alongside language-specific hosts like nREPL for Clojure and IEx for Elixir.

How do I quickly test and refine a function within a project using an eval loop?▼

You can quickly test and refine a function by evaluating code snippets incrementally in the interactive loop. This provides immediate feedback, letting you adjust code on the fly before integrating it into the main codebase.

Do I need language-specific hosts to run interactive code evaluation for dynamic languages?▼

Yes, language-specific hosts such as nREPL for Clojure and IEx for Elixir are required to run interactive code evaluation. These hosts facilitate the immediate feedback and adjustments needed for dynamic languages.
