splt

Note: This experimental tool is not officially supported by Ariga or Atlas and is provided as-is.

A small command tool to split an Atlas HCL schema file into multiple files.

Accepts input schema via a file or stdin and writes the split files to a directory.

Supported strategies:

schema: split by schema: each schema is written to a separate file.
block: split by block: each block type is written to a separate file.
resource: split to file per resource. each schema is written to a separate dir, with resources organized by types into separate directories.

Quickstart

Install:

go install github.com/rotemtam/splt/cmd/splt

Split a file:

# split by schema
atlas schema inspect --url '<db url>' | splt --output=./out --strategy=schema

Verify output is correct:

atlas schema diff --dev-url docker://postgres/16/dev --from <db url> --to file://out/

Output:

Schemas are synced, no changes to be made.
