The idea behind this package is to consolidate and simplify the use of development tools and scripts across all my repositories.

These tools might not be for you, and that's okay.

Maybe these tools help a lot, but you have different needs. That's also okay. You may fork and modify to creating your own Composer plugin.

Of course, if you want to help improve these tools, I welcome your contributions. Feel free to open issues, ask about or request features, and submit PRs. I can't wait to see what you come up with.

This project adheres to a code of conduct. By participating in this project and its community, you are expected to uphold this code.

Install this package as a development dependency using Composer.

composer require --dev chiron/devtools


This package is a Composer plugin. This means Composer recognizes that it provides custom functionality to your composer command. After installation, type composer list, and you'll see a lot of new commands that this plugin provides.

composer list

Add a Command Prefix

The commands this plugin provides are all intermingled with the rest of the Composer commands, so it may be hard to find them all. We have a way to group them by command namespace, though. Open composer.json and add a chiron/devtools.command-prefix property to the extra section. You may use any prefix you wish.

    "extra": {
        "chiron/devtools": {
            "command-prefix": "my-prefix"

Now, when you type composer list (or just composer), you'll see a section of commands that looks like this:

  my-prefix:analyze:all           Runs all static analysis checks.
  my-prefix:analyze:phpstan       Runs the PHPStan static analyzer.
  my-prefix:analyze:psalm         Runs the Psalm static analyzer.
  my-prefix:build:clean           Cleans the build/ directory.
  my-prefix:build:clean:all       Cleans the build/ directory.
  my-prefix:build:clean:cache     Cleans the build/cache/ directory.
  my-prefix:build:clean:coverage  Cleans the build/coverage/ directory.
  my-prefix:changelog             Support for working with Keep A Changelog.
  my-prefix:license               Checks dependency licenses.
  my-prefix:lint:all              Runs all linting checks.
  my-prefix:lint:fix              Auto-fixes coding standards issues, if possible.
  my-prefix:lint:pds              Validates project compliance with pds/skeleton.
  my-prefix:lint:style            Checks for coding standards issues.
  my-prefix:lint:syntax           Checks for syntax errors.
  my-prefix:test:all              Runs linting, static analysis, and unit tests.
  my-prefix:test:coverage:ci      Runs unit tests and generates CI coverage reports.
  my-prefix:test:coverage:html    Runs unit tests and generates HTML coverage report.
  my-prefix:test:unit             Runs unit tests.

You can also list commands by command prefix with composer list my-prefix.

Extending or Overriding chiron/devtools Commands

Maybe the commands chiron/devtools provides don't do everything you need, or maybe you want to replace them entirely. The configuration allows you to do this!

Using the chiron/devtools.commands property in the extra section of composer.json, you may specify any command (without your custom prefix, if you've configured one) as having other scripts to run, in addition to the command's default behavior, or you may override the default behavior entirely.

Specifying additional scripts works exactly like writing custom commands in composer.json, but the location is different. Everything you can do with a custom Composer command, you can do here because they're the same thing.

    "extra": {
        "chiron/devtools": {
            "command-prefix": "my-prefix",
            "commands": {
                "lint:all": {
                    "script": "@mylint"
                "test:all": {
                    "script": [
    "scripts": {
        "mylint": "parallel-lint src tests",
        "phpbench": "phpbench run"

In this way, when you run composer my-prefix:lint:all or composer my-prefix:test:all, it will execute the default behavior first and then run your additional commands. To override the default behavior so that it doesn't run at all and only your scripts run, specify the override property and set it to true.

    "extra": {
        "chiron/devtools": {
            "commands": {
                "lint:all": {
                    "override": true,
                    "script": "parallel-lint src tests"

Composer Command Autocompletion

Did you know you can set up your terminal to do Composer command autocompletion?

If you'd like to have Composer command autocompletion, you may use bamarni/symfony-console-autocomplete. Install it globally with Composer:

composer global require bamarni/symfony-console-autocomplete

Then, in your shell configuration file — usually ~/.bash_profile or ~/.zshrc, but it could be different depending on your settings — ensure that your global Composer bin directory is in your PATH, and evaluate the symfony-autocomplete command. This will look like this:

export PATH="$(composer config home)/vendor/bin:$PATH"
eval "$(symfony-autocomplete)"

Now, you can use the tab key to auto-complete Composer commands:

composer my-prefix:[TAB][TAB]
