inteligir Canvas
Canvas is a rough spatial surface: boxes, connectors, and relative position. It
is not a diagram renderer and not a place for readable sentences.
When To Reach For It
Use canvas when someone asks for a canvas, edits an existing one, or wants a
sketch they can rearrange. Use a plaintext code fence for a generic flow,
wireframe, or menu sketch — ASCII stays readable everywhere, including in a diff.
Use a chart for quantity and an image for anything polished.
The test: if the words matter more than where the boxes sit, canvas is the wrong
block.
The Payload
```inteligir-canvas
[inteligir:grid:v2]
[inteligir:labels:[{"id":"draft","text":"Draft","col":8,"row":4}]]
....########................
....#......#................
....########................
```
In order: the grid marker, an optional single-line labels array, then grid rows.
The grid is 120 columns by 60 rows. Missing cells pad empty, extra cells
truncate, and a saved canvas normalizes to the full size.
Every character except . and space becomes ink. Letters do not stay
readable — an A is a smudge, not a letter. All readable text goes in labels.
Labels are objects with:
| Field | Contract |
|---|
id | Unique within this canvas, non-empty |
text | Non-empty, keep under 80 characters |
col | Integer, 0–119 |
row | Integer, 0–59 |
The labels line must be valid compact JSON on one line.
Drawing Something Readable
- Count columns deliberately, or generate the rows programmatically. Hand-aligned
ASCII drifts by one character and the whole sketch skews.
- Favor rectangles, straight connectors, and generous space.
- Do not draw arrowheads out of
< and >; show direction with layout and
labels.
- Keep strokes clear of where labels sit.
- If you cannot verify the result renders, simplify it or use an ASCII fence
instead. A wrong canvas is harder to fix than a plain diagram.
Before You Finish
- The block was asked for, not substituted for a diagram.
- The grid marker and labels JSON are valid and correctly ordered.
- Every coordinate is inside 120×60 and every label id is unique.
- No readable text is hiding in the grid.
