jadpo check

On this page

Check the project for errors.

Check every Jadpo file in the project: where each file sits, how things are named, what each name refers to and who may use it, types, logic and failures. Then write the manifest and the catalogues to build/, errors or not. Without a path, the project is found by walking up to app.jadpo. A file or folder outside any project is checked on its own, with the layout rules off, and writes nothing.

usage
jadpo check [path]

Arguments

  • path (optional): A project, file or folder to check

Flags

  • --before <ref>: The branch or commit to compare with

On every command

  • --json: Print data for tools instead of text
  • --full: Show everything a report shortens
  • --help: Show every flag, with examples
  • --color <when>: Choose when to use colour

jadpo check --json writes one JSON document to standard output instead of text, with the same exit code. The document has schemaVersion, command ("check"), ok, data (what the command produced, null when it failed) and diagnostics (each error with its rule, reason, next and help). A command that needs a terminal refuses --json and names the flags that do the same job.

Examples

Errors

  • cli.check_arguments: A jadpo check command names a path that isn't there or isn't a .jadpo file, or a --before git doesn't know
  • acceptance.base_missing: Base commit the change is compared with isn't in this clone
  • acceptance.edited: Acceptance already on the before side was edited
  • acceptance.missing: A change could break someone else or widen who can do what, and no acceptance this change adds says a person agreed to it
  • acceptance.no_reason: An acceptance this change adds has no /// line above acceptance saying why a person accepted the changes it lists
  • acceptance.unmatched: Acceptance lists a change this change doesn't make
  • migration.drop_not_accepted: A migration removes data, and no acceptance in the project says a person agreed to it
