Create JiraConfig struct (url, username, api_token) - Implement JiraClient with REST API authentication - Add JiraService similar to GerritService structure 2. **JIRA Activity Metrics**: - **Tickets Created**: Issues created by user - **Tickets Resolved**: Issues resolved/closed by user - **Tickets Assigned**: Currently assigned issues - **Comments Added**: Comments/updates on issues - **Sprint Participation**: Issues completed in sprints 3. **Data Structures**: ```rust #[derive(Debug, Clone, Serialize, Deserialize)] pub struct IssueInfo { pub key: String, pub summary: String, pub status: String, pub assignee: String, pub created: String, pub resolved: Option, pub project: String, } pub struct JiraActivityMetrics { pub tickets_created: Vec, pub tickets_resolved: Vec, pub tickets_assigned: Vec, pub comments_added: u32, } ``` 4. **API Endpoints**: - `/rest/api/3/search` - JQL queries for ticket data - `/rest/api/3/issue/{issueId}` - Detailed issue information - `/rest/api/3/user/search` - User information 5. **TUI Integration**: - Add JIRA tabs to ReviewBrowser - Show ticket lists with status coloring - Link to JIRA ticket URLs for detailed viewing - Filter by project, status, date ranges ### GitLab Integration (Future Phase) **Goal**: Track merge request and repository activity **Implementation Plan**: 1. **GitLab API Client** (`src/core/gitlab.rs`) - Create GitLabConfig struct (url, access_token, username) - Implement GitLabClient with token-based authentication - Add GitLabService following established patterns 2. **GitLab Activity Metrics**: - **Merge Requests Created**: MRs authored by user - **Merge Requests Merged**: Successfully merged MRs - **Merge Requests Reviewed**: MRs where user provided reviews - **Issues Created**: Issues opened by user - **Commits Pushed**: Direct commits to repositories 3. **Data Structures**: ```rust #[derive(Debug, Clone, Serialize, Deserialize)] pub struct MergeRequestInfo { pub iid: u32, pub title: String, pub state: String, pub created_at: String, pub merged_at: Option, pub source_branch: String, pub target_branch: String, pub project_id: u32, } pub struct GitLabActivityMetrics { pub merge_requests_created: Vec, pub merge_requests_merged: Vec, pub merge_requests_reviewed: Vec, pub issues_created: Vec, pub commits_pushed: u32, } ``` 4. **API Endpoints**: - `/api/v4/merge_requests` - MR data with author/reviewer filters - `/api/v4/projects/{id}/merge_requests` - Project-specific MRs - `/api/v4/issues` - Issues with author filter - `/api/v4/users/{id}/projects` - User's project involvement 5. **TUI Integration**: - Add GitLab tabs to ReviewBrowser - Show MR lists with state indicators (Open/Merged/Closed) - Link to GitLab MR/issue URLs - Group by project/repository ### Unified Review Dashboard **Goal**: Single view across all platforms (Gerrit + JIRA + GitLab) **Architecture**: 1. **Platform Abstraction**: ```rust pub trait ReviewPlatform { async fn get_activity_metrics(&self, user: &str, days: u32) -> Result; fn get_platform_name(&self) -> &str; fn is_configured(&self) -> bool; } ``` 2. **Unified Metrics**: ```rust pub struct UnifiedActivityMetrics { pub gerrit: Option, pub jira: Option, pub gitlab: Option, } ``` 3. **Multi-Platform TUI**: - Tab-based interface for each platform - Summary view combining all platforms - Cross-platform search and filtering - Export unified reports to CSV/JSON ### Configuration Management **Updates to config.toml**: ```toml [gerrit] gerrit_url = "https://review.example.com" username = "user" http_password = "token" [jira] jira_url = "https://company.atlassian.net" username = "user@company.com" api_token = "token" [gitlab] gitlab_url = "https://gitlab.example.com" access_token = "token" username = "user" ``` ## Future Enhancements (Planned) - Quality metrics: Average comments per change, review turnaround time, success rate - Collaboration metrics: Response rates, cross-team reviews, mentoring activity - Trend analysis and historical comparisons - JSON/CSV export options - Multi-platform dashboard integration - Performance analytics and productivity insights ## Technical Notes - Using async/await for Gerrit API calls - 30-second timeout for HTTP requests - Base64 encoding for HTTP Basic Auth - URL encoding for Gerrit query parameters - Comprehensive error handling and logging
