Templates component

Greentic templating node powered by Handlebars. The only exposed operation is text.

• Debug strings: {{payload}} renders compact JSON (use {{{payload}}} for unescaped).
• Strict scoping: rendering fails if scope identifiers are missing.

Requirements

• Rust 1.91+
• wasm32-wasip2 target (rustup target add wasm32-wasip2)

Usage

Node authoring shape:

nodes:
  my_template:
    templates:
      text: "My name is {{name}}"
      routing: out   # optional, defaults to out

Context model:

• payload: current input payload
• msg: channel message envelope
• {{payload}}: compact JSON strings for debugging (triple-stash to avoid HTML escaping)

Examples:

• Payload: {{payload.name}} → pulls from payload
• Debug: {{{payload}}} → raw JSON of payload
• Control flow helpers work as usual: {{#if payload.active}}Hi{{/if}}, {{#each payload.items}}{{this}}{{/each}}
