feat: add metadata support to role markers in dotprompt#563
Conversation
Extend the `role` helper to accept key-value metadata pairs via
Handlebars hash arguments (e.g., `{{role "user" purpose="preamble"}}`).
Update the role marker format, regex, and parsing logic to encode,
split, and extract metadata. Propagate parsed metadata into message
objects via a new optional `metadata` field on messages.

Add support for passing key=value metadata to the `{{role}}` Handlebars
helper (e.g. `{{role "user" purpose="preamble"}}`). The metadata is
encoded into the role marker string, parsed back during message
construction, and stored in a new `Metadata` field on `Message`. Updates
the regex, adds `parseRoleMarker`, and includes spec tests.
Add support for passing metadata via hash parameters in the `{{role}}`
helper (e.g. `{{role "user" purpose="preamble"}}`). Metadata key-value
pairs are serialized into the role marker, parsed during message
construction, and attached to the resulting Message object. Also adds
spec test assertions for metadata on messages.
…bilities Add and update constraint dependencies to fix multiple security advisories including vulnerabilities in nbconvert, pytest, requests, tornado, pygments, and uv. Remove resolved advisory from pysentry while_no_fix ignore list.
Remove `-e` editable install entries for `dotpromptz` and `handlebarrz` from the exported requirements.txt, keeping only the dependency comments for workspace resolution.

Adds metadata support to the
rolehelper.Allow the
{{role}}helper to carry key-value metadata via Handlebars hash arguments:This lets prompt authors annotate message boundaries with arbitrary metadata (e.g., marking a message's purpose for downstream consumers or signaling cache breakpoints) without changing the message content itself. The metadata is encoded into the existing role marker format, parsed during message splitting, and surfaced on the
Message.metadatafield.Implemented across JS, Go, and Dart with shared spec tests in
spec/helpers/role_metadata.yaml.Also pins 6 vulnerable Python transitive dependencies (
nbconvert,pytest,requests,tornado,pygments,uv) to patched versions and regenerates the lock/requirements files... just to make python presubmits pass.
