Mojolicious Template Formatter

This Python program formats Mojolicious template files to make their structure easily understandable by humans. It properly indents HTML tags, Mojolicious commands, helper commands, and Perl constructs.

Features

• Proper indentation of HTML tags
• Formatting of Mojolicious command lines (% lines)
• Proper handling of Perl code blocks
• Special handling for Mojolicious-specific syntax (form_for, content_for, etc.)
• Ensures space after % when required
• Customizable indentation size
• Smart handling of non-indenting tags (br, hr, img, input, etc.)
• Special handling for lines with multiple closing tags

Usage

# Basic usage
./mojo_formatter_final.py input_file.mojo > output_file.mojo

# Read from stdin and write to stdout
cat input_file.mojo | ./mojo_formatter_final.py > output_file.mojo

# Specify custom indentation size (default is 4 spaces)
./mojo_formatter_final.py --indent 8 input_file.mojo > output_file.mojo

# Show help
./mojo_formatter_final.py --help

Examples

The formatter can handle various Mojolicious template constructs, including:

• HTML tags
• Mojolicious command lines (% lines)
• Perl code blocks
• Form blocks
• Content blocks
• Embedded Perl expressions
• Special HTML elements like <br>, <hr>, <img>, etc.

Requirements

• Python 3.x
• No external dependencies required

How It Works

The formatter uses regular expressions to identify different elements in the Mojolicious template:

1. Mojolicious command lines (starting with %)
2. HTML tags
3. Perl code blocks
4. Special Mojolicious constructs (form_for, content_for)

It then applies appropriate indentation based on the nesting level of these elements, with special handling for non-indenting tags and multiple closing tags.
