I am currently getting the following error when I attempt to run the command. 🤔

RuntimeException thrown in /var/www/html/vendor/mglaman/phpstan-drupal/src/Drupal/DrupalAutoloader.php on line 68 while loading bootstrap file /var/www/html/vendor/mglaman/phpstan-drupal/drupal-autoloader.php: Unable to detect Drupal at 
Failed to run phpstan : exit status 1

It might be because drupalfinder can't find Drupal. Drush no longer uses drupalfinder as it has not had a release in like 5 years. Composer can now find Drupal root. I'll talk to mgalalm

You can work around this by setting up the config.extra key in composer.json as usual.

"installer-paths": {
            "web/core": [
                "type:drupal-core"
            ],
            "web/libraries/{$name}": [
                "type:drupal-library"
            ],
            "web/modules/contrib/{$name}": [
                "type:drupal-module"
            ],
            "web/profiles/contrib/{$name}": [
                "type:drupal-profile"
            ],
            "web/themes/contrib/{$name}": [
                "type:drupal-theme"
            ],
            "drush/contrib/{$name}": [
                "type:drupal-drush"
            ]
        }

Will be fixed by webflo/drupal-finder#64 if that gets merged

[bimsonz]

• 🚀 would love to see this get in

Would be also nice to add an example in README how to create a PHPStan baseline file for your contrib module via this DDEV phpstan command to help module maintainers and contributors with it :)

From above on this issue:

Will be fixed by webflo/drupal-finder#64 if that gets merged

That got merged 2 weeks ago, but I'm still seeing issues with the current PR as it is coded.

But there is good news.

While looking into this, I stumbled across this key information:

Not sure about the implication, but running ddev expand-composer-json allows me to run PHPStan

If I copy the first two lines from .ddev/commands/web/poser into .ddev/commands/web/phpstan, it works!

These lines:

export COMPOSER=composer.contrib.json
.ddev/commands/web/expand-composer-json "$DDEV_PROJECT_NAME"

The full contents of .ddev/commands/web/phpstan:

#!/bin/bash

#ddev-generated
## Command provided by https://github.com/ddev/ddev-drupal-contrib
## Description: Run phpstan inside the web container
## Usage: phpstan [flags] [args]
## Example: "ddev phpstan" or "ddev phpstan -n"
## ProjectTypes: drupal,drupal8,drupal9,drupal10
## ExecRaw: true

if ! command -v phpstan >/dev/null; then
  echo "phpstan is not available. You may need to 'ddev composer install'"
  exit 1
fi
export COMPOSER=composer.contrib.json
.ddev/commands/web/expand-composer-json "$DDEV_PROJECT_NAME"
phpstan analyse $DDEV_DOCROOT/modules/custom "$@"

I guess I don't have permission to update a PR from someone else. (I miss the "Get Push Access" we have on Drupal MRs here).

So ddev phpstan is turning up different results than Drupal's GitLabCI.

Fixed by pulling in phpstan.neon file from gitlab_templates project:

Updated working command:

#!/bin/bash

#ddev-generated
## Command provided by https://github.com/ddev/ddev-drupal-contrib
## Description: Run phpstan inside the web container
## Usage: phpstan [flags] [args]
## Example: "ddev phpstan" or "ddev phpstan -n"
## ProjectTypes: drupal,drupal8,drupal9,drupal10
## ExecRaw: true

if ! command -v phpstan >/dev/null; then
  echo "phpstan is not available. You may need to 'ddev composer install'"
  exit 1
fi
test -e phpstan.neon || curl -OL https://git.drupalcode.org/project/gitlab_templates/-/raw/default-ref/assets/phpstan.neon
export COMPOSER=composer.contrib.json
.ddev/commands/web/expand-composer-json "$DDEV_PROJECT_NAME"
phpstan analyse $DDEV_DOCROOT/modules/custom "$@"

I created a new PR #53 building on the work here following methodology from https://stackoverflow.com/a/39807499/413538. I fixed merge conflicts and created separate commits for the different pieces I've mentioned above in previous comments.
