Get ddev working for alt text validation

Tested locally by comparing ddev config in https://www.drupal.org/project/tragedy_commons → to this module and tested it locally. Changes in https://git.drupalcode.org/project/alt_text_validation/-/merge_requests/26. The test is to check out the branch and run the commands from CONTRIBUTING.md to see if you can spin up the site locally.

I am running into this error on running 'ddev poser'

@swirt try it now. I think the minimum-stability and other composer values is likely what caused the issue so I switched those values and removed some.

FYI here is example https://git.drupalcode.org/project/svg_image_field/-/merge_requests/26/d... I followed for the contributing file.

@dmundra thank you for working on this again.

If do the following:

1. git pull (to pull your new changes
2. ddev delete (to make sure I have a blank slate)
3. ddev start

I get the following error

PHP Fatal error:  Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 8.2.0". You are running 8.1.30. in /var/www/html/vendor/composer/platform_check.php on line 24

I just pushed up a commit to resolve the php version.

Repeating the steps above results in a success for 'ddev start'
However, running `ddev poser` again fails with the same error as I started with

Writing output to composer.contrib.json
PHP Fatal error:  Uncaught Error: Class "Composer\XdebugHandler\XdebugHandler" not found in /var/www/html/vendor/composer/composer/bin/composer:29

Ya Steve still baffling why you are getting this error. I pulled down your changes, did ddev deleted and was able to get it to work. FYI what is your composer version? Here is mine:

dmundra in ~/workspace/community/alt_text_validation on branch 3503655-get-ddev-working > composer --version
Composer version 2.8.4 2024-12-11 11:57:47

Mine seems to match yours exactly

ddev composer -V
Composer version 2.8.5 2025-01-21 15:23:40
PHP version 8.2.27 (/usr/bin/php8.2)

Thank you @dmundra for taking this on. This is all up and running now.

Other than a couple minor tweaks in that last commit, the solution for me was to

1. ddev delete
2. delete the entire clone
3. git clone the repo again.

Thank you @swirt.

This went out with 1.0.0-alpha6 → .
