-----------------------------------
Summary: camel-tui: Unify view and edit mode rendering to use a
single TextArea-based path
Key: CAMEL-24395
URL: https://issues.apache.org/jira/browse/CAMEL-24395
Project: Camel
Issue Type: Improvement
Components: camel-jbang
Reporter: Claus Ibsen
The Source tab has two separate rendering paths for view mode (Paragraph widget
+ custom line rendering) and edit mode (TextArea widget + post-render
overlays). This causes:
- Duplicated logic for line numbers, syntax highlighting, cursor marker, doc
panel, scroll
- Visual shifts when switching between view and edit mode (F4) because the two
renderers have slightly different layout math
- Scroll position not preserved across mode switches
The proposed fix: always render using TextArea (even in view mode as
read-only). One rendering path, one scroll system, seamless F4 transitions.
Features that need migration from the Paragraph-based view renderer:
- Format cycling (YAML/Java/XML route dump)
- Jump links (crosshair arrows to linked routes)
- Markdown toggle for .md files
- Horizontal scroll (scrollX)
- Deprecated line scanning
- Plain mode (borderless for copy/paste)
