Drupal 9 compatible

There are more changes then just in the info.yml needed ...

Sorry my bad, this is the only thing missing in the automated patch

Was too quick, your patch does not respect non-D9, and the omega_tools module also needs an updated core_version_requirement

Attaching updated patch which fixes some more deprecated code.

@divyesh19 the above patch#7 does not apply, whereas on applying #6 patch apply cleanly but throws an error: "The website encountered an unexpected error. Please try again later".

I was just working on this same issue & have been running into error using composer. Both patched on this issue fail because of the changes in the `*.info.yml` files. This is the same problem that I have been having. The patch I am uploading DOES NOT contain any `*.info.yml` updates, but it contains a lot of updates I found via `drupal-check` to replace deprecated code that will not be available in D9.

I hope it helps!

Any advice on how to get past the issues I'm having with the `*.info.yml` files would be appreciated.

Use this fork here. See https://www.drupal.org/docs/develop/git/using-git-to-contribute-to-drupa...

Or add your own repository in composer.json, like

       "my/omega": {
          "type": "package",
          "package": {
              "name": "my/omega",
              "version": "dev-df96ba3",
              "source": {
                  "type": "git",
                  "url": "https://git.drupalcode.org/project/omega.git",
                  "reference": "df96ba3"
              },
              "require": {
                  "drupal/core": "^8.8 || ^9.0"
              },
              "type": "drupal-theme"
          }
        }

require cweagans/composer-patches

and in the extra section of your composer.json, add

        "enable-patching": true,
        "patches": {
            "my/omega": {
                "d9": "https://www.drupal.org/files/issues/2020-06-06/omega.5.x-dev.rector.patch",
                "d9 info": "https://www.drupal.org/files/issues/2020-12-18/3169332-d9_info_ymls-6.patch",
                "d9 comp": "patches/omega-term.patch",
                "warnings and errors": "patches/omega2.patch"
            }
        },

remove drupal/omega and add my/omega.

Patch for upgrading to Drupal 9 for alpha7 version

Patch in #13 worked for me.

Still ran into 1 error.

omega-functions.php line 120
$vocab = $term->getVocabularyId(); should be $vocab = $term->bundle();

@Wilson2100 I have pulled down the "remotes/origin/3169332-drupal-9-compatible" branch, should i now be applying the previous patches in this thread to it?
Sorry im not very familiar with git and branch merging etc, currently I have just been applying patches manually.

When i try to apply patches with git I always get "error: patch failed"

Hi @PavelGerasuta, Tried to apply your patch on alpha 7 version but I can't, it gives error
Could not apply the patch! Skipping. The error was: Cannot apply patch https://www.drupal.org/files/issues/2021-11-08/Drupal_9_compatible_alpha_7-3169332-15.patch
Can you please check or suggest if there is something wrong?

Thank you in Advance!

This theme is not compatible with 9.3.15. Seeking an alternative. Looks like Bartik as a base theme might be the wiser route to go.

@ytsurk nice composer solution. The patch fails on (d9 comp) and (warnings and errors). Is that bit missing? Because it has an error "The website encountered an unexpected error. Please try again later." 500 any non-admin page. It says "Error: Class 'Drupal\omega\Theme\OmegaSettingsInfo' not found" and the settings page is broken. Ideas?
