Lintrule

What is Lintrule?

Lintrule is a command-line tool that leverages large language models (LLMs) to automate code reviews. It allows teams to enforce coding policies that linters might miss, find bugs that tests don't catch, and ensure consistent code quality without manual effort.

How does Lintrule work?

Lintrule operates by running checks against code diffs. It works with Git to identify changes since the last commit (or other specified diffs) and applies user-defined rules written in plain language to these changes. The tool then uses an LLM to analyze the code against these rules and flags any violations.

Key Features:

• Plain Language Rules: Define code review rules in simple, human-readable language.
• Git Integration: Integrates seamlessly with Git to review code changes.
• Parallel Processing: Runs checks in parallel to minimize review time.
• Customizable: Tailor rules to match specific project requirements and coding standards.
• Cost Estimation: Provides tools to estimate the cost of running Lintrule based on code volume.

How to use Lintrule?

1. Installation: Install Lintrule using the provided shell script:

   curl -fsSL https://lintrule.com/install.sh | bash
   

2. Initialization: Set up a .rules folder in your codebase using the rules init command.
3. Login: Authenticate with Lintrule using the rules login command.
4. Rule Definition: Create rule files (e.g., .rules/no-bugs.md) with instructions written in plain language.
5. Check Code: Run the rules check command to analyze code against the defined rules.

Why choose Lintrule?

Lintrule offers several advantages for development teams:

• Saves Time: Automates code review, reducing the manual effort required.
• Enforces Consistency: Ensures adherence to coding standards across the team.
• Finds Hidden Bugs: Discovers bugs that linters and tests might miss.
• Reduces Costs: Optimizes code quality, potentially lowering maintenance costs.

Who is Lintrule for?

Lintrule is suitable for:

• Software development teams of all sizes.
• Projects with complex coding standards.
• Teams looking to improve code quality and reduce bugs.
• Organizations seeking to automate compliance checks (e.g., SOC2).

Pricing

Lintrule pricing is based on the number of lines of code changed, with a rate of $1.00 per 1,000 lines. The tool provides an estimation command to help users understand potential costs. Small projects with ~4 contributors may cost around $20 per ruleset per month, while larger projects can range from $150 to $250 per month.

Examples

• SOC2 Compliance: Enforce rules to prevent logging customer data to maintain SOC2 certification.
• Migration Safety: Ensure database migrations do not cause issues in PostgreSQL 8 environments.

FAQ

• Does Lintrule run on diffs?

  Yes, Lintrule operates on code diffs by default, comparing changes since the last commit.

• Does it have false positives?

  Like any code review process, Lintrule may produce false positives. The key to minimizing these is to create specific and detailed rules.

• How do I make it cheaper?

  You can reduce costs by running Lintrule only on pull requests, consolidating rules, and siloing rules to specific files.

• Is it slow?

  No, Lintrule processes rules in parallel, ensuring checks complete quickly, typically within a few seconds.
