Import from eraser.io

The code panel accepts eraser.io diagram code as a one-shot import. Pasted text that smells like eraser gets a Convert hint; converting rewrites it into this language, and drawing proceeds through the normal compiler. Eraser is an import format; Koboyo diagram code is the editing format.

Family detection#

Eraser code carries no header, so the transpiler detects the family from the text:

• keyed field lines and dotted relations mean erd;
• blocks and activations mean sequence;
• cloud icons mean architecture;
• otherwise flowchart.

The detected header is prepended to the output.

An example#

This eraser flow:

Compute [icon: aws-ec2] > Storage [icon: aws-s3]
Storage > Database [icon: aws-rds]

converts to Koboyo code that renders like this:

Compute [aws/ec2]
Storage [aws/simple-storage-service]
Database [aws/rds]

Compute -> Storage -> Database

Cardinality and connectors#

• ERD relations use eraser's cardinality: > for N:1, < for 1:N, - for 1:1, <> for N:M.
• Graph and sequence connectors normalize to ours: > becomes ->, <> becomes <->; plain lines (-, --) become arrows with a note.
• Table icons are dropped with a diagnostic (entities take only a colour); styleMode, typeface, and autoNumber lines are commented out.

Idempotent#

Every input line maps to one output line, so diagnostics point at the converted text. Text that already starts with a family header passes through untouched, so converting the same input twice is safe.
