Upgrade rivo/tview to v0.42.0

Problem to solve

The current version of rivo/tview is v0.0.0-20230621164836-6cc0565babaf. There has been a recent release that introduces Semantic Versioning. The library is generally backwards-compatible by default

Proposal

Upgrade the package and verify behavior with unit tests

Further details

The newer version also introduces Pages.GetPage(), which can be used instead of the current manual page tracking approach:

Current Approach: Manual tracking with maps view.go

var (
    boxes     map[string]*tview.TextView  // For pipeline visualization 
    logViews  map[string]*tview.TextView  // For log content (search functionality)
)

// Store TextView manually
if logViews == nil {
    logViews = make(map[string]*tview.TextView)
}
logViews[logsKey] = tv

// Retrieve TextView manually
if logViews != nil {
    if tv, exists := logViews[logsKey]; exists {
        logContent = tv.GetText(false)
    }
}

Proposed Approach with GetPage()

func getLogContent(jobName string) string {
    logsKey := "logs-" + jobName
    if page := root.GetPage(logsKey); page != nil {
        if tv, ok := page.(*tview.TextView); ok {
            return tv.GetText(false)
        }
    }
    return ""
}

Benefits:

• Eliminate separate tracking maps (reduced complexity)
• Let tview manage page lifecycle (memory efficiency)
• Less manual state synchronization required (bug risk reduced)
