smix-migrate

Static maestro YAML flow → smix canonical YAML codemod.

Not required for correctness — smix already accepts maestro yaml directly. This crate exists to normalize corpora: canonical verb names for grep, smix-native argument shapes for tooling, deprecated-form flagging for cleanup.

CLI (via smix migrate)

# stdin/stdout
cat flow.yaml | smix migrate > flow.smix.yaml

# single file, print to stdout
smix migrate flow.yaml

# in-place batch
smix migrate --in-place flows/*.yaml

Any unrecognized verb (runScript, evalScript, etc.) is preserved verbatim with a WARN: line to stderr.

Library

use smix_migrate::Migrator;

let (canonical_yaml, report) = Migrator::default().migrate(maestro_yaml)?;
println!("{} renames, {} unknown verbs", report.renamed.len(), report.unknown_verbs.len());

Rules

See DEFAULT_RULES in src/lib.rs for the current 20-rule table.

Non-goals

• Comment preservation (serde_norway loses # comments; documented at CLI)
• Linting / correctness checks
• Formatting (indentation follows serde_norway defaults)
