Code Checker

The tool called Code-Checker checks and possibly repairs some of the formal errors in your source code.

Installation

Code Checker should be installed as project, don't use it as dependency.

composer create-project nette/code-checker

Usage

Usage: php code-checker [options]

Options:
    -d <path>             Folder or file to scan (default: current directory)
    -i | --ignore <mask>  Files to ignore
    -f | --fix            Fixes files
    -l | --eol            Convert newline characters
    --no-progress         Do not show progress dots
    --strict-types        Checks whether PHP 7.0 directive strict_types is enabled

Without parameters, it checks the current working directory in a read-only mode, with -f parameter it fixes files.

Before you get to know the tool, be sure to backup your files first.

You can create a batch file, e.g. code.bat, for easier execution of Code-Checker under Windows:

php path_to\Nette_tools\Code-Checker\code-checker %*
