lhy-formatter-linter 0.0.10

This package provides formatters and linters for CMake, C++, and Python, making it ideal for developers who work with both C++ and Python.

Generic formatter and linter

This package provides formatters and linters for CMake, C++, and Python, making it ideal for developers who work with both C++ and Python.

Getting Started

Installation

pip install lhy-formatter-linter

Usage

The formatter or linter will recursively scan your project directory, formatting or linting all CMake, C++, and Python code using third-party tools.

third-party tool	cmake	C++	python
formatter	cmake-format	clang-format	yapf, isort
linter	cmake-lint	clang-tidy	flake8

lhy -h
usage: lhy [-h] {format,lint} ...

code formatter and linter.

positional arguments:
  {format,lint}
    format       Format code
    lint         Lint code

format code in yout project

lhy format -p <project-root-dir> 

lint code in yout project

lhy lint -p <project-root-dir> 

Optional arguments

Choose languages

Users can choose to format or lint one or more languages by using the -l or --language option.

lhy format -p <project-root-dir> -l cmake

lhy lint -p <project-root-dir> -l python

lhy lint -p <project-root-dir> -l cmake cxx

Ignore no-source directories

In a project, there are typically subdirectories that do not contain source code.

By default, lhy-formatter-linter ignores the following directories at the top level under the project root directory:

• .git
• build
• .vscode
• .cache
• .pytest_cache

Users can add custom subdirectories to ignore using the optional argument -id or --ignore-dirs. The format of the subdirectories to ignore can be either an absolute path or a relative path to the project root directory.

lhy format -p <project-root-dir> --ignore-dirs .github py_venv <project_root_dir>/docs

lhy lint -p <project-root-dir> --ignore-dirs <project_root_dir>/.github  <project_root_dir>/py_venv docs

Alternatively, users can specify a text file that contains the directories to ignore, with one directory per line.

For example, a file named dirs-to-ignore.txt could have the following content:

<project_root_dir>/.github
<project_root_dir>/py_venv
docs

Then, use the optional argument -ig or --ignore-file to specify the file containing the directories to ignore, which will be parsed by the formatter or linter.

lhy format -p <project-root-dir> --ignore-file dirs-to-ignore.txt

Format or lint config files

By default, the formatter or linter will use the format or lint configuration files located directly under the project root directory.

Users can place their own custom format and lint configuration files directly under the project root directory to override the default settings and apply their own custom formatting or linting rules.

└── user
    ├── project_root_dir
    │   ├── src
    │   ├── .clang-format
    │   ├── .clang-tidy
    │   ├── .cmake-format
    │   ├── .flake8
    │   ├── .style.yapf
    │   └── .isort.cfg

Alternatively, users can specify the configuration file paths using the following optional arguments:

                        Path of cmake lint custom config file (default: None)

optional c++ format arguments:
  --clang-tidy-config CLANG_TIDY_CONFIG
                        Path of clang tidy custom config file (default: None)

optional python format arguments:

    --flake8-config <flake8-config-absolute-file-path>

Integrate to CI

This package can be integrated into a Continuous Integration (CI) pipeline to ensure that all code on the remote repository conforms to the specified norms and standards.

jenkins example.

stage('Check code') {
    agent any
    steps {
        sh 'lhy lint -p <project_root_dir>'
        sh 'lhy format -p <project_root_dir>'
        sh 'git diff --exit-code'
    }
}
