aivane-template-linter 0.1.1

Static linter for AIVane templates and application bundles

AIVane Template Linter

aivane-template-linter is a Python CLI for validating AIVane template JSON files and application bundles before they are sent to the Android REPL runtime.

It checks single templates, recursive template directories, and application directories that contain app.json, __main__.json, and child templates.

Install

uv tool install aivane-template-linter

Or with pipx:

pipx install aivane-template-linter

Run

Lint one template:

aivane-template-lint template.json

Lint an application bundle directory:

aivane-template-lint path/to/my-app -r

Emit machine-readable JSON:

aivane-template-lint path/to/my-app -r --json

Treat warnings as failures:

aivane-template-lint path/to/my-app -r --strict

Use a custom OperationType schema directory:

aivane-template-lint path/to/my-app -r --docs-dir path/to/operation-types

By default, the package uses the OperationType schema snapshot bundled with the installed wheel.

What It Checks

• JSON parse errors
• Required template and operation fields
• Unknown OperationTypes
• Missing, unknown, deprecated, mistyped, or invalid enum parameters
• Variable references that are not declared in the current template scope
• break and continue outside loop context
• Nested operation structure
• Application-level relationships when app.json is present
• template.execute targets and parameter contracts across templates

Application Checks

When a directory contains app.json, the linter also checks the template graph:

• app.mainTemplateId resolves to exactly one template
• template IDs and file aliases are not duplicated
• every template.execute.templateId target exists
• required child template input parameters are passed
• extra parameters passed to child templates are reported as warnings

Exit Codes

• 0: no errors
• 1: one or more errors, or warnings when --strict is used

The same exit-code behavior applies to --json.

Development
