⚡ Quick Start in 30 Seconds

code --install-extension Nihilnia.nihilanth-toolbox

1. Summon Slash Commands: On a dedicated line in any .ts, .js, or .json file, type / or press Ctrl+Alt+Space (Cmd+Alt+Space on macOS).
2. Instant Dummy Data: Type /data users 3 --format=json and hit Tab or Enter.
3. Type-Driven Mocking: Highlight or define any TypeScript type or interface and run /data from UserProfile 5.
4. Recall Lost Code: Accidentally delete a function or type declaration? Just type the first two letters of its name anywhere in your project to restore it.

📸 Visual Feature Tour

1. Type-Driven Mock Data & Slash Commands

Parse local TypeScript interfaces, types, unions, and tuples directly at your cursor to generate deterministic, structurally matched mock datasets in milliseconds.

---

2. Automatic Workspace Code Memory

Passively observes declarations and deleted code fragments (>24 characters) across JS/TS/JSX/TSX files. As soon as you type two letters of any past identifier, Nihilanth offers both the standalone identifier name and the complete implementation body.

---

3. Selection Transformations

Select any snippet or JSON payload and press Ctrl+Alt+Space (or right-click) to trigger instant transformations: convert JSON to TypeScript types, switch JSON to JS object literals, deduplicate arrays, extract keys, or convert naming conventions.

---

4. 100% Offline & Private Architecture

Your code never leaves your workstation. No background telemetry pings, no cloud models, no API quotas, and no subscription paywalls.

🌟 Key Capabilities

🕒 Automatic Workspace Code Memory Passively captures function, class, type, and interface declarations as well as deleted blocks across your files. Restores deleted implementations right from your cursor suggestions.	📌 Cross-Project Snippet Pins Save reusable code blocks with custom aliases, tags, and dynamic VS Code placeholder syntax (${1:param}). Pinned snippets are available across all workspaces and never expire.
🎲 Deterministic Dummy Data Generate arrays or single instances of common schemas (users, products, emails, IDs, timestamps) with reproducible seed control (--seed=42) and edge-case boundary testing.	🧬 TypeScript Type Mocking Understands your active file's TypeScript AST. Run /data from <Type> [count] to produce conforming mock data with zero manual configuration.
🔄 Selection Transformations Instantly convert between strict JSON and JavaScript object literals, infer TypeScript types from JSON payloads, deduplicate arrays, and switch casing (camel, Pascal, snake, kebab).	🐉 Nihilanth Dragon Theme & Status Launcher Features an embedded vector dragon status bar launcher and an optional bespoke product icon theme for sleek, high-contrast suggestion badges.

⚡ Slash Commands Reference

Type / at the beginning of a dedicated line (leading indentation is preserved). Suggestions filter dynamically as you type arguments.

Supported Commands

Command	Arguments	Description	Example
/recall	<query> [--project=current]	Search stored identifiers, declarations, and deleted code fragments.	/recall authService
/snippet	<alias | tag> [--project=current]	Insert a pinned snippet across workspaces. Expands TabStops.	/snippet fetchUsers
/data	<preset> [count] [flags]	Generate synthetic test data from built-in schemas.	/data users 5 --format=json
/data from	<Type> [count] [flags]	Parse a local TypeScript type or interface and output conforming mock data.	/data from Order 3 --seed=101

Built-in Presets

Plural (Generates Array)	Singular (Generates Single Value / Object)
users, products	user, product
names, emails, ids	name, email, id
numbers, dates, booleans, strings	number, date, boolean, string

CLI Flags & Edge Cases

• --format=json: Emits strict JSON with quoted keys.
• --format=js: Emits native JavaScript / TypeScript object literals.
• --seed=<number>: Creates deterministic, 100% reproducible pseudo-random output.
• --edge=empty: Generates an empty array (tests zero-state UI).
• --edge=long: Stretches string fields to extreme lengths (tests UI overflow & wrapping).
• --edge=boundary: Uses extreme numeric limits (0, -1, Number.MIN_SAFE_INTEGER, Number.MAX_SAFE_INTEGER).

🔄 Selection Transformations Reference

Highlight any text and press Ctrl+Alt+Space or choose Transform Selection:

Transformation	Description
JSON ↔ JS Object	Seamlessly toggle between strict JSON format and clean JS object literals.
JSON → TypeScript Type	Infers and generates a clean type GeneratedType = { ... } from a JSON sample.
Extract Keys / Values / Entries	Pulls out object keys, values, or [key, value] tuple pairs from selected objects.
Deduplicate Array	Removes duplicates from selected primitive lists or JSON arrays.
Case Conversions	Switch text between camelCase, PascalCase, snake_case, and kebab-case.

All transformations operate purely in memory on the selected text and are fully reversible with native Undo (Ctrl+Z).

🐉 Dragon Product Icon Theme (Optional)

To display the custom teal dragon glyph beside Nihilanth completion items:

1. Open the Command Palette (Ctrl+Shift+P / Cmd+Shift+P).
2. Run Preferences: Product Icon Theme.
3. Select Nihilanth Dragon.

(Standard VS Code icons gracefully fall back to defaults; switching themes retains the dragon launcher in your status bar).

---

⚙️ Settings & Configuration

Configure Nihilanth in your VS Code settings (settings.json):

Setting	Default	Description
nihilanth.prefix	"/"	The character sequence used to trigger slash commands on dedicated lines.
nihilanth.captureEnabled	true	Automatically record observed declarations and deleted fragments.
nihilanth.historyLimitMB	100	Storage cap in MB for automatic memory. Least recently seen or used items are evicted first; pins never expire.
nihilanth.defaultCount	5	Default number of items generated for array presets.
nihilanth.maxDocumentKB	512	Upper file size limit (in KB) for automatic AST observation.
nihilanth.excludedFolders	["node_modules", ".git", "dist", "out", "build", "coverage"]	Folders excluded from capture.
nihilanth.excludedFiles	[".env", ".env.local"]	Specific files ignored to safeguard secrets.

🛡️ Privacy & Storage Architecture

• Local Storage Only: Memory entries are stored unencrypted in VS Code's local extension globalStorage as a versioned, append-only JSON Lines log (memory-v2.jsonl). Older memory-v1.json databases are migrated automatically and kept as memory-v1.json.migrated.
• Isolated from Source Control: History is never committed to Git, workspace files, or Settings Sync.
• Concurrency Safe: Locked appends and atomic compaction keep the log consistent across multiple open VS Code windows. A damaged database is never overwritten; Nihilanth offers to move it aside and start fresh.
• Secret Safeguards (best effort): Only JS/TS/JSX/TSX documents are observed, and excluded folders and files are skipped. Declarations and fragments that look like credentials (private keys, well-known token formats such as sk-…, ghp_…, AKIA…, or a string literal assigned to names like apiKey, password, token) are not captured. This is a heuristic — remembered code can be offered in other projects, so pause capture (or add exclusions) for sensitive codebases.
• Untrusted Workspaces: Automatic capture is paused until you trust the workspace; everything else keeps working.
• Management Controls:
  • Nihilanth Toolbox: Manage Memory and Snippets — Browse, filter, pin, or delete stored entries.
  • Nihilanth Toolbox: Pause / Resume Code Capture — Temporarily suspend code observation.
  • Nihilanth Toolbox: Clear Automatic History — Instantly purge unpinned history while preserving saved snippets.
