SRCL

Live Demo

SRCL is an open-source React component and style repository that helps you build web applications, desktop applications, and static websites with terminal aesthetics. Its modular, easy-to-use components emphasize precise monospace character spacing and line heights, enabling you to quickly copy and paste implementations while maintaining a clean, efficient codebase.

npm install
npm run dev

Go to http://localhost:10000 in your browser of choice.

We use Vercel for hosting.

Tests

Run the unit tests for the sacred CLI framework primitives:

npm test

This runs three gates: TypeScript type-check, the vitest suite, and the Python unittest suite (which includes a parity test between the JS and Python CLI runtimes). If python3 is not on your PATH, the Python suite skips with a warning. Use npm run test:js or npm run test:python to run a single suite.

Sacred CLI Templates

Sacred ships a tiny zero-dependency CLI framework under scripts/cli/lib. The framework reads its palette from scripts/cli/colors.json so the terminal surface and the React surface stay in agreement. Two reference templates render the same data set in two languages:

npm run cli:typescript
npm run cli:python

cli:typescript runs scripts/cli/templates/template.ts via tsx. cli:python runs scripts/python/templates/template.py against a snake_case Python mirror of the framework under scripts/python/sacred_cli. Both screens use the alt screen buffer and raw mode keyboard input — press Esc or Ctrl-C to exit. The same template is also mounted as a React component on the kitchen sink page (search for CLI TEMPLATE EXAMPLE).

If you want to write your own CLI screen or port a sacred React surface to a terminal, the four porting skills under skills/ walk through the conventions:

• skills/port-sacred-terminal-ui-to-typescript-cli/SKILL.md
• skills/port-sacred-terminal-ui-to-python/SKILL.md
• skills/port-sacred-terminal-ui-to-react-using-same-conventions/SKILL.md
• skills/port-sacred-terminal-ui-to-hostile-react-codebase/SKILL.md

Documentation URLs

Every doc and component source file in the repo is published at a stable URL so humans and agents can read them without cloning:

• https://sacred.computer/llms.txt — llmstxt.org index, grouped into Repo conventions, Simulacrum (CLI framework), Skills, and Component source
• https://sacred.computer/llms-full.txt — every doc concatenated in one fetch
• https://sacred.computer/llm/AGENTS.md — root sacred / Simulacrum conventions
• https://sacred.computer/llm/components/AGENTS.md — canonical catalog of every sacred React component (props, theming tokens, CLI primitive equivalent)
• https://sacred.computer/llm/components/Card.tsx.txt — raw source of a component (every components/*.tsx follows this pattern)
• https://sacred.computer/llm/scripts/cli/AGENTS.md — Simulacrum TypeScript framework
• https://sacred.computer/llm/scripts/python/AGENTS.md — Simulacrum Python mirror
• https://sacred.computer/llm/skills/port-sacred-terminal-ui-to-typescript-cli/SKILL.md
• https://sacred.computer/llm/skills/port-sacred-terminal-ui-to-python/SKILL.md
• https://sacred.computer/llm/skills/port-sacred-terminal-ui-to-react-using-same-conventions/SKILL.md
• https://sacred.computer/llm/skills/port-sacred-terminal-ui-to-hostile-react-codebase/SKILL.md
• https://sacred.computer/llm/skills/fast-typescript-check/SKILL.md — keep this repo's TypeScript fast to type-check and fast to run

Adding a new doc or component file to the repo automatically exposes it as a URL. Both /llms.txt and /llms-full.txt follow the llmstxt.org convention.
