xian-tech-linter 0.3.3

Smart contract linter for the Xian blockchain

xian-linter

xian-linter is a Python linter specifically for Xian smart contracts. It combines PyFlakes with the structured linter exposed by xian-contracting, so rule violations include stable error codes and source positions.

The published PyPI package name is xian-tech-linter. The import package and console command remain xian_linter and xian-linter.

Quick Start

Base package:

pip install xian-tech-linter

Inline use:

from xian_linter import lint_code_inline

errors = lint_code_inline("def transfer():\n    pass\n")

Structured sync API:

from xian_linter import LintErrorModel, lint_code_sync

errors: list[LintErrorModel] = lint_code_sync(
    "@export\ndef transfer():\n    return missing_name\n"
)

Principles

• Keep the package focused on contract linting, not runtime execution.
• Expose the same rule surface in both inline and server modes.
• Prefer stable error codes and positions so tooling can build on top of the linter reliably.
• Keep the structured result types importable from the package root so callers do not need to reach into internal modules.
• Keep server mode optional. The core package should still be useful as a local linting dependency.
