Validation ​

Taplo supports validation of TOML files, by default it will only look for syntax errors and some semantic errors such as duplicate keys.

taplo check foo.toml

Schema Validation ​

Taplo supports validation via JSON Schemas (Draft 4).

Using a Specific Schema ​

taplo check --schema https://example.com/foo-schema.json foo.toml

Using a Schema Catalog ​

Taplo supports schema catalogs such as the JSON Schema Store for retrieving schemas and matching them to files via file names.

You can enable this by either specifying a catalog via the --schema-catalog flag, or enabling the use of the default catalogs via --default-schema-catalogs.
