natrix 0.1.9

A Vyper linter for fine sneks.

Natrix

Natrix is a vyper linter that checks for common mistakes in vyper contracts. It is designed to be your vyper copilot, helping you to write code that is more secure and efficient.

Installation

You can install Natrix using pip:

pip install natrix

Currently natrix requires uv to be installed to function correctly.

Vyper Version Compatibility

Natrix supports Vyper compiler versions 0.4.0 and above.

Usage

To check a contract:

natrix lint file_to_lint.vy

To check all vyper contract in the current directory:

natrix lint
# or simply
natrix

To generate explicit exports for a contract:

natrix codegen exports path/to/contract.vy

Command Line Options

natrix --help                         # Show help message
natrix --version                      # Show version information
natrix lint --list-rules               # List all available rules
natrix lint --disable NTX1 NTX2       # Disable specific rules
natrix lint --rule-config RuleName.param=value  # Configure rule parameters
natrix lint -p /path/to/libs /another/path  # Add extra paths for imports
natrix codegen exports contract.vy    # Generate explicit exports

Configuration

You can configure Natrix using a pyproject.toml file in your project root:

[tool.natrix]
# Files or directories to lint (relative to pyproject.toml)
files = ["contracts/", "tests/contracts/"]

# Additional paths to search for imports
path = ["lib", "vendor/contracts"]

# Rules to disable
disabled_rules = ["NTX1", "NTX2"]

# Rule-specific configurations
[tool.natrix.rule_configs.RuleName]
param = "value"

Pre-commit hook

Natrix can also be used as a pre-commit hook. This allows to have your contracts checked automatically before you can commit.

To add natrix just add the following lines to your pre-commit-config.yaml config file:

repos:
  - repo: https://github.com/albertocentonze/natrix
    rev: v0.1.9  # Use the latest version
    hooks:
      - id: natrix

and then install pre-commit in your repository by doing:

pre-commit install

Disclaimer

Natrix is highly experimental software, I do not take any responsibility for changes to the codebase suggested by this linter that might lead to loss of funds or any other issue.
