GramIt is a powerful Rust-based tool that combines and visualizes your code files, creating instant PlantUML diagrams for easy understanding and documentation of your project structure.
- 📁 Combine multiple source files into a single output
- 🗂️ Support for multiple file extensions
- 🔍 Customizable ignore patterns with support for multiple patterns
- 📊 Automatic PlantUML diagram generation with customizable output
- 📏 Line limit option for large codebases
- 🚫 Optional exclusion of import and export statements
- ⚙️ Configuration file support for easy setup and multiple runs
- 🎨 Custom PlantUML instructions support for advanced diagram customization

You can run gramit either using command-line arguments or a configuration file.
Run gramit with the following command:
gramit [OPTIONS]
--help
: Display the help message--path=<directory>
: Specify a source directory (can be used multiple times)--output=<file>
: Specify the output file path--ext=<extensions>
: Comma-separated list of file extensions to process (default: rs)--ignore=<pattern>
: Custom glob pattern for files to ignore (can be used multiple times)--max-lines=<number>
: Maximum number of lines per output file (enables pagination)--ignore-imports=<bool>
: Whether to ignore import statements (default: true)--ignore-exports=<bool>
: Whether to ignore export statements (default: true)--auto-generate
: Automatically generate PlantUML diagram without prompt--plantuml-dir=<directory>
: Specify the output directory for PlantUML diagrams--plantuml-filename=<name>
: Specify the filename for PlantUML diagrams (without extension)--plantuml-no-timestamp
: Exclude timestamp from PlantUML diagram filename
-
Basic usage:
gramit --path=/project/src --output=./combined_code.txt
-
Multiple directories with custom extensions and ignore patterns:
gramit --path=/project/src --path=/project/tests --output=./combined.rs --ext=rs,py --ignore=*.tmp --ignore=**/node_modules/**
-
Customize PlantUML output:
gramit --path=/project --output=./combined_code.txt --plantuml-dir=./diagrams --plantuml-filename=project_structure --plantuml-no-timestamp
Create a file named gramit.config.json
in the same directory as the executable. The file should contain an array of configuration objects:
[
{
"source_dirs": ["./src", "./tests"],
"output_file": "./output/combined_1.txt",
"file_extensions": ["rs", "toml"],
"custom_ignore_patterns": ["*.tmp", "**/node_modules/**"],
"max_lines_per_file": 1000,
"auto_generate_diagram": true,
"plantuml_output_dir": "./diagrams",
"plantuml_output_filename": "project_structure",
"plantuml_include_timestamp": true,
"plantuml_custom_instructions": "Forget about sequence diagram, generate a user flow diagram instead."
},
{
"source_dirs": ["./docs"],
"output_file": "./output/combined_docs.txt",
"file_extensions": ["md", "txt"],
"ignore_imports": false,
"ignore_exports": false,
"auto_generate_diagram": false
}
]
When a configuration file is present, gramit will process each configuration sequentially.
gramit generates:
- A combined text file containing the processed code
- A PlantUML diagram (PNG format) visualizing the code structure
The locations of these files will be displayed in the console output.
You can add custom PlantUML instructions to your diagrams by using the plantuml_custom_instructions
field in your configuration file. This allows you to add any other PlantUML-specific instructions that should apply to the entire diagram.
Example:
"plantuml_custom_instructions": "Explain like im 5"
