SQL Formatter Pre-Commit Hook

This repository includes a pre-configured pre-commit hook to automatically format SQL and PL/SQL files before each commit, ensuring consistent code style across the project. It leverages Trivadis' advanced format settings for alignment, spacing, and other formatting standards.

Features

• Automatic Formatting: Formats SQL files with specified extensions to maintain code consistency.
• Supported File Types: Includes common SQL and PL/SQL file extensions such as .sql, .prc, .fnc, .pks, .pkb, .trg, .pls, and more.
• Configurable Settings: Uses trivadis_advanced_format.xml for advanced formatting configurations, which can be customized as needed.
• Flexible SQLcl Path: Allows specifying the SQLcl path using the SQL_PROGRAM environment variable.

Requirements

SQLcl

This pre-commit hook requires Oracle SQLcl (SQL Command Line) to perform SQL formatting. SQLcl provides powerful SQL scripting and formatting capabilities. Follow these steps to download and install it:

• Download SQLcl: The latest version can be downloaded from Oracle SQLcl Downloads.
• Install SQLcl: Refer to the installation guide if needed.

Optional: Set SQLcl Path

If SQLcl is not in your system PATH or if you want to specify a custom path, set the SQL_PROGRAM environment variable to the path of the sql binary. For example:

export SQL_PROGRAM="/path/to/sqlcl/bin/sql"

Git

Ensure Git is installed as this pre-commit hook uses Git’s pre-commit hook system.

Installation

To use this hook with pre-commit, add it to your .pre-commit-config.yaml file in the target repository. Here’s an example configuration:

# .pre-commit-config.yaml
repos:
- repo: https://github.com/GentleGhostCoder/oracle-formatter-pre-commit-hook  # Replace with your GitHub repo URL
  rev: v1.0.0  # Use a tag, branch name, or commit SHA
  hooks:
    - id: oracle-formatter-hook

Then, install the hook by running:

pre-commit install

This command sets up the pre-commit hook to run automatically before each commit.

How It Works

1. Identify Relevant Files: The hook detects files based on specified extensions.
2. Format Files: Each identified file is formatted using formatter/format.js via SQLcl, applying the settings in trivadis_advanced_format.xml.

Usage

1. Stage SQL Files: Stage files for commit using git add.
2. Commit Changes: Commit staged files with git commit. The pre-commit hook will automatically format applicable files.

Running Manually with --all-files

To format all files, not just staged files, you can run the pre-commit hook manually:

pre-commit run --all-files

This triggers the formatting of all files matching the specified extensions in the repository.

Manual Formatting with the Python Entry Point

To manually format files without running the pre-commit hook, use the orafmt command directly if your module is installed:

orafmt file1.sql file2.sql

Alternatively, you can use the Python script directly:

python3 -m orafmt file1.sql file2.sql

This command will format the specified files according to the configurations.

Advanced Configuration

To modify formatting settings, edit the trivadis_advanced_format.xml file. These options allow customization of alignment, line breaks, and spacing based on project needs.
