Stoplight Prism is an open-source HTTP mock server and validation proxy driven by OpenAPI specifications (v2, v3, v3.1) and Postman Collections. It provides two primary CLI commands: `prism mock` to simulate an API from a schema definition, and `prism proxy` to validate requests and responses against a spec while forwarding traffic to a real upstream. The architecture is a monorepo with four packages (`core`, `http`, `http-server`, `cli`) that implement a functional pipeline: route matching, input validation (body, headers, query/path parameters, security), content negotiation, and response generation (static examples or dynamic faker-generated data). It also supports callback mocking, CORS handling, and RFC 7807 problem detail errors. The codebase is written in TypeScript with heavy use of fp-ts for composable error handling and dependency injection via reader monads. While the project is mature and well-tested (unit, integration, and a text-based harness test suite), its tight coupling to Stoplight internal packages and the steep learning curve of fp-ts reduce its overall reusability for external projects. It is not a data research repository.
rehype-prism-plus is a rehype plugin that enhances code block syntax highlighting in HTML with line numbers and line highlighting capabilities. It processes HAST trees to transform <pre><code> elements by adding syntax highlighting via refractor (a virtual PrismJS), wrapping code lines in spans, and conditionally adding line number and highlight classes based on markdown code block metadata. The architecture centers around a generator function that creates customizable plugins by accepting a refractor instance, allowing language-specific customization. Key entry points include the default export (all languages), common.js (subset of languages), and generator.js (custom language sets). Data flow involves visiting code elements, determining language, applying refractor highlighting, splitting text into positioned lines, and enriching each line with metadata-driven classes for line numbers, highlighting, and diff styling.
react-syntax-highlighter is a React component library for syntax highlighting that supports two major backends: highlight.js (via lowlight) and Prism (via refractor). It renders syntax-highlighted code into React virtual DOM with inline styles, avoiding `dangerouslySetInnerHTML`. The architecture is built around a core highlighter factory in `src/highlight.js` that takes an AST generator and produces `<pre>`/`<code>` structures with optional line numbers, line wrapping, custom renderers, and style injection. The library provides both statically bundled builds (all languages included) and light/async variants that support dynamic language registration and code splitting via Webpack's `import()` comments. This enables consumers to reduce bundle size by loading only the languages they need, both synchronously and asynchronously. Beyond the core highlighter, the repository includes a massive collection of auto-generated theme and language files—over 90 highlight.js themes and 40+ Prism themes, plus hundreds of language definitions—all exported as JavaScript objects. Build scripts in `scripts/` generate these assets from upstream packages, ensuring theme CSS is parsed and camel-cased into inline style objects. The library also exports a `createElement` utility and a `checkForListedLanguage` helper, and supports custom renderer plugins (e.g., virtualized rendering for large blocks of code). Although the codebase is functionally complete and well-tested, it suffers from moderate technical drift due to outdated dependencies, lack of TypeScript definitions, and a fragile generated file structure that is tightly coupled to specific versions of highlight.js and prismjs.
ggprism is an R package that extends ggplot2 to replicate the visual aesthetics of GraphPad Prism. It provides themes, color/fill/shape palettes, and specialized geoms/guides to create publication-ready plots matching Prism's default styling. Key functionalities include applying Prism-like themes via `theme_prism()`, using discrete palettes with `scale_*_prism()` functions, adding statistical annotations (e.g., p-value brackets) with `add_pvalue()` and `geom_bracket()`, and customizing axes with specialized guides like `guide_prism_offset()` for offset ticks. The package follows ggplot2 extension conventions, using ggproto for custom geoms, discrete_scale for scales, and guide objects for axis modifications. It includes built-in datasets (e.g., wing morphology data) and relies on standard R datasets in examples. External dependencies center on ggplot2, scales, and rlang, with optional packages like ggnewscale and patchwork used in vignettes.
