It works with PHP, Latte, NEON, JSON and YAML files, checking encoding, line endings, indentation, trailing whitespace and more. It runs as a standalone application, not as a project dependency. Documentation can be found on the [website](https://doc.nette.org/tools/code-checker). If you like it, **[please make a donation now](https://github.com/sponsors/dg)**. Thank you! Installation ------------ [](#installation) Install it globally via Composer: ``` composer global require nette/code-checker ``` Make sure your global Composer `bin` directory is in your [`PATH`](https://getcomposer.org/doc/03-cli.md#global). The `code-checker` command is then available from anywhere, on any operating system. Alternatively, install it as a standalone project: ``` composer create-project nette/code-checker ``` It requires PHP 8.0 or higher. Usage ----- [](#usage) By default, Code Checker runs in **read-only mode** and only reports the problems it finds: ``` code-checker ``` To actually repair the files, add `--fix`. **Back up your files first**, or run it on a clean working tree so you can review the changes afterwards with `git diff`: ``` code-checker --fix ``` You can limit the scan to a specific path, skip files, or run faster syntax-only checks: ``` code-checker -d src --ignore "temp/*" code-checker --only-syntax ``` In read-only mode the tool exits with code `0` when everything is fine and `1` when any problem is found, so it fits nicely into CI pipelines. Full list of options: ``` Usage: code-checker [options] Options: -d Folder or file to scan (default: current directory) -i | --ignore Files to ignore -f | --fix Fix the files -l | --eol Normalize line endings to the system default --only-syntax Check syntax only (faster) --no-progress Do not show progress dots --version Show version ``` What Code Checker Does ---------------------- [](#what-code-checker-does) - checks the syntax of **PHP**, **Latte**, **NEON** and **JSON** files - removes the [BOM](https://doc.nette.org/glossary#toc-bom) - verifies that files are valid **UTF-8** - checks for [control characters](https://doc.nette.org/glossary#toc-control-characters) - detects malformed phpDoc comments around annotations (e.g. `/* @var` instead of `/** @var`) - checks that PHP files declare `strict_types=1` - enforces tabs for indentation in PHP, CSS, JS and TS files, and spaces in YAML - removes trailing whitespace and blank lines at the end of files - normalizes line endings to the system default (with the `-l` parameter) ### Health Score 69 — FairBetter than 100% of packages Maintenance96 Actively maintained with recent releases Popularity54 Moderate usage in the ecosystem Community29 Small or concentrated contributor base Maturity80 Battle-tested with a long release history Bus Factor1 Top contributor holds 97.2% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
