--------------------------------
Issue Type: Improvement (was: Bug)
> camel-jbang - TUI layout overflow at 120 columns (tab bar, footer, minimum
> size)
> --------------------------------------------------------------------------------
>
> Key: CAMEL-23841
> URL: https://issues.apache.org/jira/browse/CAMEL-23841
> Project: Camel
> Issue Type: Improvement
> Components: camel-jbang
> Reporter: Adriano Machado
> Assignee: Adriano Machado
> Priority: Major
>
> The Camel TUI has two rendering issues visible at 120x43 \(a common terminal
> size\) and no minimum\-size safeguard.
> h2. 1. Tab bar clips the last entry
> The full tab bar string \( "{{ 1 Overview | 2 Log | ... | 0 More▾ }}" \)
> requires \~126 characters. At 120 columns the last label clips to a bare
> {{0}}, hiding the "More▾" label entirely.
> h2. 2. Footer overflows mid\-word on some tabs
> Tab\-specific footers on several tabs exceed the terminal width
> significantly. For example, the Diagram tab footer requires \~170\-186
> characters and the Errors tab footer \~169\-199 characters. The terminal
> clips the last visible hint mid\-word \(e.g., {{e ex}} instead of {{e
> export}}, {{d diagra}} instead of {{d diagram}}\).
> h2. 3. No minimum terminal size handling
> Resizing the terminal below a sensible minimum produces corrupted or clipped
> output with no feedback to the user.
> h2. Resize behavior
> TamboUI already re\-invokes {{render\(Frame\)}} with the current terminal
> dimensions on every resize event. This means all three fixes work
> automatically when the user resizes the terminal while the app is running:
> the tab bar switches display mode, the footer drops or restores hints, and
> the too\-small screen appears or clears — all without any additional event
> handling code.
> h2. Proposed fix* _Tab bar:_ Add two display modes. At 126\+ columns use the
> current full labels. At 80\-125 columns switch to compact mode \(strip outer
> spaces from labels, use {{|}} instead of {{ | }} as divider\), reducing the
> total to \~88 characters.
> * _Footer:_ After assembling all hint spans, sum their character widths. If
> the total exceeds the terminal width, drop decorative right\-side spans
> \(recording, MCP status\) first, then drop left\-side hints from the end one
> at a time, preserving the first tab\-specific hint and {{F1 help}} always.
> * _Minimum size:_ Below 80 columns or 24 rows, skip all rendering and show a
> centered message \(matching btop's style\): current dimensions highlighted in
> color when below minimum, required dimensions in white. Normal rendering
> resumes as soon as the user resizes above the threshold.
