Goals

Project Abstract: Enhancing the stdlib REPL for Interactive JavaScript Computing

Introduction:

As someone deeply involved in the JavaScript ecosystem, I recognize the importance of a robust and feature-rich REPL for Node.js. While the existing Node.js REPL serves its purpose, it lacks many of the features found in other REPL environments, particularly those catering to numerical computing and data analysis tasks. This project is my endeavor to enhance the stdlib REPL for Node.js, transforming it into a powerful tool for interactive JavaScript computing.

High-level overview of the interaction flow between components and how users interact with the enhanced stdlib REPL to perform JavaScript computing tasks efficiently.

Let's address some concerns, outlining specific functions and strategies for each aspect:

Syntax Highlighting and Theming:

Approach:

  1. Utilize a library like chalk or ansi-colors for terminal styling.
  2. Implement theme-based syntax highlighting to adapt to users' terminal themes.

Functions:

  1. applySyntaxHighlighting(code, theme): Apply syntax highlighting to code using the specified theme.
  2. setSyntaxHighlightingTheme(theme): Allow users to set their preferred theme for syntax highlighting.
  3. getDefaultTheme(): Provide default themes suitable for various terminal backgrounds.

Custom Syntax Highlighting Themes:

Approach:

  1. Define a JSON schema for theme configuration.
  2. Allow users to specify theme colors for different syntax elements.

Functions:

  1. loadTheme(themeConfig): Load a custom theme configuration provided by the user.
  2. validateTheme(themeConfig): Validate the theme configuration against the predefined schema.
  3. saveTheme(themeConfig): Save user-defined themes for future use.
