# @suaveplan/templates

A plugin-based string template engine for TypeScript. Resolves `{variable}` and `{variable:transform}` tokens in strings using a priority-sorted, regex-scan pipeline — no eval, no AST parser overhead. Designed for filling templates in notification messages, email subjects, file name patterns, code generation, and similar string-expansion tasks. Ships nine built-in plugins: dot-notation and array-index variable resolution; case, regex, and split transforms; counter, datetime, and UUID dynamic generators; and conditional/loop control flow. Three preset bundles (`minimal`, `standard`, `full`) let you trade features for bundle size. The injectable `Clock` and `Rng` make every rendering call deterministic in tests. Do not confuse with `@suaveplan/i18n`, which handles locale-keyed message catalogs and plural forms — use this package when your source strings are already in the target language and you only need token substitution.

## When to use this skill

- Implementing or debugging code that imports `@suaveplan/templates`.
- The task touches: see package README.
- You need API guidance for this package's exports.

## Quick reference

```ts
import { /* see API Reference below */ } from "@suaveplan/templates";
```

## Dependencies

Workspace dependencies: `@suaveplan/error`, `@suaveplan/types`

## Where to read more

This skill is intentionally short. The package's own documentation is the authoritative source — read these in order:

1. **`packages/foundation/templates/README.md`** — overview, install, quick-start, module index
2. **`packages/foundation/templates/src/**/*.md`** — co-located docs per implementation file (Purpose, Features, Basic + Advanced examples, full API reference, Implementation notes — all packages  ship ≥200 words per module)
3. **`packages/foundation/templates/package.json`** `exports` map — every subpath you can import from

When the user asks an API question, read the relevant co-located `.md` first; do not answer from training-data memory.
