Claus Ibsen updated CAMEL-26353:

> Key: CAMEL-26353
> URL: https://issues.apache.org/jira/browse/CAMEL-26353
> Project: Camel
> Issue Type: Improvement
> Components: camel-diagram, camel-jbang
> Reporter: Claus Ibsen
> Priority: Minor
> Fix For: 4.25.0
>
>
> The PNG of a route diagram (camel cmd route-diagram, the
> camel_render_route_diagram MCP tool, the route-diagram developer console with
> format=png) draws each step as a card with an icon, its kind and its detail
> (CAMEL-26348). A card is taller than the old box, so a large route makes a
> tall image, and it reaches the size limit of an image (16384 pixels) sooner,
> where the command says to narrow the routes with --filter. The ASCII and
> Unicode diagrams have one level only too: a box per step.
> The diagram of the Camel CLI in the terminal (camel tui, the Diagram tab) has
> zoom levels for this, see "Zoom and Folding" in
> docs/user-manual/modules/ROOT/pages/camel-jbang-tui-diagram.adoc, and
> RouteDensity / RouteDiagramZoom in camel-jbang-plugin-tui:
> * detailed: a box per step, with up to three lines of text
> * compact: a box per step with one line of text, the steps closer together
> (about twice as many steps fit)
> * bare: no boxes, each step a mark and its text on one row, the branches side
> by side
> * overview: each step a cell in the colour of its EIP, to see the shape of a
> large route
> * fit: the most detailed level in which the whole route fits
> Today these levels are only in the terminal UI. Make them available from the
> command line as well, for the image and for the text diagrams: camel cmd
> route-diagram --zoom=detailed|compact|bare|overview|fit, the same option for
> the camel_render_route_diagram MCP tool, and a zoom query parameter for the
> route-diagram developer console.
> The text diagrams matter for AI agents: an agent runs camel cmd route-diagram
> (or calls the MCP tool) with --theme=unicode or ascii and shows the diagram
> in its answer. A bare or compact text diagram of a large route fits a chat
> answer where the detailed one of today does not, and the agent can pick the
> level with fit, or zoom in on the part it talks about.
> * Image: detailed is the card of today, compact a card of one line (the kind
> and its detail on one line, a smaller icon), bare a mark and its text,
> overview cells. Fit picks the most detailed level whose image is not taller
> than a given height (or the size limit).
> * ASCII and Unicode: the same levels as the terminal UI draws them (bare and
> overview are text already there), with fit to a given number of rows or
> columns.
> The levels are worked out in camel-jbang-plugin-tui today (RouteDensity,
> RouteDiagramWidget). Moving what decides a level (the room per step, the
> gaps, the text per step) into camel-diagram, beside RouteDiagramLayoutEngine,
> lets the terminal UI, the CLI and the MCP tool share it, so the three show
> the same diagram at the same level.
> What each level keeps of the body types on the arrows (CAMEL-26351) and the
> problems of the steps (CAMEL-26352): at compact the labels and callouts as
> they are; at bare and overview the warning marks, with the problems in the
> numbered list below the route.
