Workaround to make a Drupal module compatible with D9 and D10 together
The Drupal 10 release, as described, is mostly about deprecations and removing old code. So it's pretty easy to port your modules to Drupal 10, they said!
But actually - not!
Together with deprecations, we have some libraries updated to the new major versions too, and this can bring you little unexpected surprises when you try to make your module compatible with both Drupal 9 and 10 versions together.
Launch VS Code IDE inside a Docker container
- You don’t even need to install the language package (PHP, Node.js, Go, etc) and all other tools locally on your host system, you only need to have the VS Code app (or even Free/Libre Open Source VS Codium app).
- You'll got a native app experience with local graphical interface, but all operations are performed inside the container.
- You'll use for development the same versions of language compiler (php or other) and tools (composer, phpcs and others) as installed in th

How to create a custom Drupal Entity Type in a single PHP file
Most of instructions about creating a new custom Drupal Entity Type describes that you need to create a lot of files: routing, links, form, list builder, interfaces, etc.

Using systemd as user service manager with systemctl and journalctl in userspace
Common systemd usage is to manage global linux services, that can be created/modified only with root/sudo credentials.
But systemd have the great user mode, that allow to create and control any services without sudo permissions, that runs as user owner, we simply need to add the `--user` argument.
For allow to start user services on system boot, you must one-time launch the command for needed user:
sudo loginctl enable-linger LOGIN
Delete all available tables on PostgreSQL database without schema permissions
DO $$ DECLARE r RECORD; BEGIN FOR r IN (SELECT tablename FROM pg_tables WHERE schemaname = current_schema()) LOOP EXECUTE 'DROP TABLE IF EXISTS ' || quote_ident(r.tablename) || ' CASCADE'; END LOOP; END $$;
This query will delete all available tables for current user and schema, without needs to have SCHEMA privileges.
The most popular solution via:
DROP SCHEMA public CASCADE; CREATE SCHEMA public;
Often shows the error, because of missing owner permissions or other restrictions:
How to eval PHP code via drush without escaping quotes routine
Very often there is a need to execute via
drush eval command the PHP code with both single and double quotes, something like this:
