# hive-template

The one template language the hyperhive workspace renders with: Jinja, through
[`minijinja`](https://crates.io/crates/minijinja). A value is `{{ name }}`, a
block is `{% if cond %}...{% endif %}`, and a lone `{` or `}` stays plain text.

- **`render(template, &context)`**: the text, or a message when the template
  does not parse or names a variable the context lacks. An unknown variable is
  an error, never an empty string.
- A block tag alone on its line leaves no line behind (`trim_blocks` and
  `lstrip_blocks` are on), so a template ending in a block tag and a newline
  loses that newline.
- **`variables(template)`**: the variables the template reads, so a caller can
  refuse an unknown field when the template is saved instead of when it renders.

Used by the notification router's flow templates (`swarm-notify-router`,
`swarm-wire`).
