This is a Redmine plugin that allows administrators to define custom Ruby scripts that execute on lifecycle events (before_save, after_save, before_destroy, after_destroy, etc.) for various Redmine objects such as Issue, User, Group, Project, Attachment, TimeEntry, Version, WikiContent, and more. It uses Rails monkey-patching (prepend) to inject callbacks into Redmine models and controllers, and executes user-defined scripts via `instance_eval` in the context of the observed object. The plugin provides a web UI for managing workflows, supports import/export via XML, and includes a custom mailer for sending emails from workflows. It is well-structured, has comprehensive tests, localization support, and CI integration. The codebase is mature and actively maintained, targeting Redmine 6.x and Rails 8.1.
This is a Redmine plugin that adds helpdesk functionality by enabling email-based ticket creation and facilitating email communication with ticket submitters. The system patches Redmine's core MailHandler, Journal, and Mailer classes to intercept incoming emails, track sender information, and send notifications to support clients when ticket updates are made. Key features include customizable email templates with macro expansion, CC handling, automatic reopening of closed issues via email, and support for anonymous users as support clients. The architecture follows Redmine plugin conventions with clear separation between mailers, view hooks, and core functionality patches.
