#! code: Drupal 10: Creating Custom Context Providers

Posted on by Michael G

I previously looked at injecting context providers into context aware plugins. This time I will explore more about creating our own context providers to plug into this system.

The context provider system is an ideal way to provide context to context aware plugins, with blocks being the prime example. You would use a context provider to inject an entity or value into the block so that actions can be taken using that data.

For example, we could load the current node from the route using context so that we didn’t have to bake the route provider logic into the block.

The values we inject also plug into the cache systems and so we don’t need to worry about making sure we integrate the cache systems for each type of context within the block system. Cache contexts is all taken care of in the block plugin code.

In this article I will look at why you might want to create a context provider, how to create one, and some examples of them in use.

By default, Drupal comes with the following context providers:

  • Current language context (provided by DrupalCoreLanguageContextProviderCurrentLanguageContext).
  • The node entity from the current route (provided by DrupalnodeContextProviderNodeRouteContext).
  • The taxonomy term entity from the current route (provided by DrupaltaxonomyContextProviderTermRouteContext).
  • The current user (provided by DrupaluserContextProviderCurrentUserContext).

This gives us a variety of contexts that are commonly used, but there are many reasons why we would want to create our own context providers. Here are some examples of potential contexts we could create using this system.

News about GNU Parallel:

GNU Parallel – For people who live life in the parallel lane.

If you like GNU Parallel record a video testimonial: Say who you are, what you use GNU Parallel for, how it helps you, and what you like most about it. Include a command that uses GNU Parallel if you feel like it.

About GNU Parallel

GNU Parallel is a shell tool for executing jobs in parallel using one or more computers. A job can be a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. A job can also be a command that reads from a pipe. GNU Parallel can then split the input and pipe it into commands in parallel.

If you use xargs and tee today you will find GNU Parallel very easy to use as GNU Parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU Parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU Parallel can even replace nested loops.

GNU Parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU Parallel as input for other programs.

For example you can run this to convert all jpeg files into png and gif files and have a progress bar:

  parallel –bar convert {1} {1.}.{2} ::: *.jpg ::: png gif

Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs:

  find . -name ‘*.jpg’ |

    parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: – ::: 50 100 200

About GNU SQL

GNU sql aims to give a simple, unified interface for accessing databases through all the different databases’ command line clients. So far the focus has been on giving a common way to specify login information (protocol, username, password, hostname, and port number), size (database and table size), and running queries.

The database is addressed using a DBURL. If commands are left out you will get that database’s interactive shell.

About GNU Niceload

GNU niceload slows down a program when the computer load average (or other system activity) is above a certain limit. When the limit is reached the program will be suspended for some time. If the limit is a soft limit the program will be allowed to run for short amounts of time before being suspended again. If the limit is a hard limit the program will only be allowed to run when the system is below the limit.
