Implementation Plan:

1. JIRA API Client (src/core/jira.rs)

   • 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:

   #[derive(Debug, Clone, Serialize, Deserialize)]
   pub struct IssueInfo {
       pub key: String,
       pub summary: String,
       pub status: String,
       pub assignee: String,
       pub created: String,

       pub tickets_resolved: Vec<IssueInfo>,
       pub tickets_assigned: Vec<IssueInfo>,
       pub comments_added: u32,
   }
   

4. API Endpoints:

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

Unified Review Dashboard

Goal: Single view across all platforms (Gerrit + JIRA + GitLab)

Architecture:

1. Platform Abstraction:

   pub trait ReviewPlatform {
       async fn get_activity_metrics(&self, user: &str, days: u32) -> Result<PlatformMetrics>;
       fn get_platform_name(&self) -> &str;
       fn is_configured(&self) -> bool;
   }
   

2. Unified Metrics:

   pub struct UnifiedActivityMetrics {
       pub gerrit: Option<DetailedActivityMetrics>,
       pub jira: Option<JiraActivityMetrics>,
       pub gitlab: Option<GitLabActivityMetrics>,
   }
   

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:

[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
