> camel-tui - YAML editor: undo/redo, block-aware move/duplicate/delete for EIP
> nodes
> -----------------------------------------------------------------------------------
>
> Key: CAMEL-24372
> URL: https://issues.apache.org/jira/browse/CAMEL-24372
> Project: Camel
> Issue Type: Improvement
> Components: camel-jbang
> Reporter: Claus Ibsen
> Assignee: Omar Atie
> Priority: Major
> Fix For: 4.23.0
>
>
> The TUI Source tab YAML editor currently supports basic character-level
> editing (insert, delete, cursor movement, auto-indent, Tab completion,
> validate on save). Several common editor operations are missing that would
> elevate it from a basic text editor into a proper low-code tool for Camel
> routes.
> The key insight is that operations like move, duplicate, and delete should be
> *YAML-structure-aware* -- operating on entire EIP/node blocks rather than
> single lines. In YAML DSL, a single EIP step is often multiple lines:
> {code:yaml}
> steps:
> - setHeader:
> name: foo
> simple: "${body}"
> - to:
> uri: kafka:myTopic
> parameters:
> brokers: localhost:9092
> - log:
> message: "Done"
> {code}
> Moving one line at a time is not useful here. What users need is to move the
> entire {{- setHeader:}} block (all 3 lines) as a unit, swapping it with the
> adjacent sibling {{- to:}} block (all 4 lines). Block boundaries can be
> detected from the {{- }} list item prefix and indentation level.
> The editor already has the YAML DSL model from the catalog for Tab
> completion, so it has structural awareness to know where blocks start and end.
> h3. YAML DSL editing (block-aware)
> # *Undo / Redo* (Ctrl+Z / Ctrl+Shift+Z) -- needs an undo stack in
> TextAreaState or SourceViewer
> # *Move EIP block up/down* (Alt+Up / Alt+Down) -- swap entire sibling blocks,
> not single lines
> # *Duplicate EIP block* (Ctrl+D) -- duplicate the whole block, useful for
> adding similar steps
> # *Delete EIP block* (Ctrl+Shift+K) -- delete the entire block at once
> # *Word-level navigation* (Ctrl+Left / Ctrl+Right / Ctrl+Backspace) -- jump
> and delete by word
> # *Smart Home* -- first press goes to first non-whitespace, second press to
> column 0
> # *Find in edit mode* (Ctrl+F) -- search exists in view mode but not while
> editing
> # *Comment toggle* (Ctrl+/) -- add/remove # prefix on current line or block
> h3. application.properties editing
> Properties files are line-oriented so standard line-level operations work
> fine here.
> # *Comment toggle* (Ctrl+/) -- the #1 operation in properties files. Comment
> out a property to disable it, uncomment to re-enable. Users do this
> constantly when experimenting with configuration.
> # *Value completion* -- Tab completion already works for property keys, but
> offering completions for values would be very useful: boolean (true/false),
> enum-typed options (e.g. {{camel.main.profile=}} offering dev/prod), duration
> format hints (10s, 5m, 1h), component schemes.
> # *Duplicate line* (Ctrl+D) -- handy when adding similar properties.
> # *Delete line* (Ctrl+Shift+K) -- quick removal of a property.
> # *Inline value validation* -- key validation exists on save, but validating
> values (wrong type, invalid enum, malformed duration) would catch mistakes
> earlier.
> Note: Undo/Redo and Comment toggle apply to both YAML and properties files.
