PGPM module AST — plan/control/SQL-header parsers and the lossless module read/write layer
The pgpm module AST — the plan/control/SQL-header parsers (files/*) and the
lossless module read/write layer (module/*) that composes them into a single typed
PgpmModuleAst.
readModule(dir) / parseModule(dir) — parse a pgpm module directory into a typed AST.writeModule(ast, { outDir }) / deparseModule(ast) — serialize the AST back to a
module (byte-lossless for modules read via readModule).files/* — the low-level parsers/writers everything else composes; no re-implementation.This package is a pure leaf (no database, no deploy engine). @pgpmjs/core and the
migration-bundle artifact layer build on top of it. See the pgpm-migration-bundle skill
for how the bundle layer uses this AST.
