- Fix duplicate name="url" form fields by adding :disabled binding
to each URL input so only the active target type's field submits
- Fix message formatting to use Slack mrkdwn (*bold*) instead of
Markdown (**bold**) and remove language hint from code blocks
- Fix README line exceeding 80-column hard wrap
Add a new 'slack' target type that sends webhook events as formatted
messages to any Slack-compatible incoming webhook URL (Slack, Mattermost,
and other compatible services).
Messages include event metadata (method, content type, timestamp, body
size) and the payload pretty-printed in a code block. JSON payloads are
automatically formatted with indentation; non-JSON payloads are shown as
raw text. Large payloads are truncated at 3500 chars.
Changes:
- Add TargetTypeSlack constant to model_target.go
- Add SlackTargetConfig struct and deliverSlack method to delivery engine
- Add FormatSlackMessage (exported) for building Slack message text
- Route slack targets in processDelivery switch
- Handle slack type in HandleTargetCreate with webhook_url config
- Add slack option to source_detail.html target creation form
- Add comprehensive tests (config parsing, message formatting, delivery
success/failure, routing)
- Update README with slack target documentation
- README.md: remove 'in development mode' from admin user creation
description (admin user creation is unconditional)
- internal/delivery/engine.go: remove 'and retry' from HTTPTargetConfig
comment (retry was merged into http target type)
- internal/delivery/engine_test.go: remove '/retry' from
newHTTPTargetConfig comment for consistency
