C language utils and tools based on the `clang` and `binutils` modules.

## Installation

Install clanguru using `pipx` for isolated installation:

```shell
pipx install clanguru
```

## Usage

Clanguru provides four main commands for C/C++ code analysis and utility operations:

- **Documentation**: Generate (minimal) documentation for C/C++ sources functions and classes.
  It supports multiple output formats including Myst Markdown, standard Markdown, and RestructuredText.
- **Testing**: Create mock objects for unit testing C functions
- **Analysis**: Understand object file dependencies and symbol usage. It can generate HTML and Excel reports.

Check the help message for more details:

```shell
clanguru --help

```

For detailed help on each command, use the `--help` option with the command name.

```shell
clanguru analyze --help
```

### Object File Analysis

Clanguru can analyze object files to understand their dependencies and symbol usage.
For this, you need to build your project and provide the compilation database (`compile_commands.json`).
Also, ensure that the `nm` command-line tool is available in your system PATH.

To generate an html dynamic dependency report, run the following command:

```shell
clanguru analyze --compilation-database compile_commands.json --output-file dependencies.html --use-parent-deps
```

> [!NOTE]
> Here is the generated HTML report for my smart home temperature sensor project: https://maxiniuc.com/objects_deps/index.html.
> I only wrote some lines of code to make a temperature sensor available as a `matter` device but the esp32 modules, matter stack,
> and all the libraries bring a lot of code and dependencies. 🫣
> Feel free to move the nodes around and explore the dependencies.


If the output file ends with `.xlsx`, an Excel report will be generated instead of an HTML one.

## Contributing

The project uses UV for dependencies management and packaging and the [pypeline](https://github.com/cuinixam/pypeline) for streamlining the development workflow.
Use pipx (or your favorite package manager) to install the `pypeline` in an isolated environment:

```shell
pipx install pypeline-runner
```

To bootstrap the project and run all the steps configured in the `pypeline.yaml` file, execute the following command:

```shell
pypeline run
```

For those using [VS Code](https://code.visualstudio.com/) there are tasks defined for the most common commands:

- run tests
- run pre-commit checks (linters, formatters, etc.)
- generate documentation

See the `.vscode/tasks.json` for more details.
