General

needs major refactoring!!



  • Drupal dev docs - "Newcomers to Drupal development should read the conceptual information provided in the 'Components of Drupal' section, and then proceed to examine one of the heavily-documented example modules below. The examples are fully-functioning Drupal modules, so you can download them from the contributions repository and alter them as you experiment."




Command-line

Composer


composer update 'drupal/*' --with-dependencies

php -d memory_limit=-1 composer require zaporylie/composer-drupal-optimizations

composer remove drupal/admin_toolbar_search


"drupal/core": "9.0 as 8.9"
   # version alias

Drush

  • Drush - a command line shell and Unix scripting interface for Drupal. Drush core ships with lots of useful commands for interacting with code like modules/themes/profiles. Similarly, it runs update.php, executes sql queries and DB migrations, and misc utilities like run cron or clear cache. Drush can be extended by 3rd party commandfiles.
composer require drush/drush
composer require drush/drush:^10


  • https://github.com/drush-ops/drush-launcher - In order to avoid dependency issues, it is best to require Drush on a per-project basis via Composer (composer require drush/drush). This makes Drush available to your project by placing it at vendor/bin/drush.However, it is inconvenient to type vendor/bin/drush in order to execute Drush commands. By installing the drush launcher globally on your local machine, you can simply type drush on the command line, and the launcher will find and execute the project specific version of drush located in your project's vendor directory.




Commands

I have dr as an alias for drush.


drush updatedb --no-interaction --yes

drush watchdog:show


drush help
  alll the commands!
drush help --filter
  choose which help category to echo
drush cc all
  clear cache
drush pml
  list installed and enabled modules

drush dl [project]
  download project
drush dl sasson-7.x-3.x-dev
  download sasson dev release
drush updb
  run upgrade.php
drush en [project] -y
  enable project without confirmation
drush dis [project] -y
  disable project

drush pm-uninstall [project]
  remove project from db
drush sql-cli < example.sql
drush php-eval 'echo drush_get_context("DRUSH_DRUPAL_ROOT");'
drush php-eval 'echo drush_locate_root() . "/" . drupal_get_path('theme', 'sasson');'

drush eval 'echo theme_get_setting('sasson_compiler') . "\n" ;'
  otherwise gives trailing issue?
drush vset --yes site_offline_message "This site is being maintained";

drush vset --yes site_offline 1;

In Drupal 7 to simply put the site into maintenance mode:

drush vset --yes maintenance_mode 1;
drush user-login ryan
  displays a one-time login link for the user ryan. 
open `drush user-login ryan`
  open said link in browser
dr uli

Site aliases

Drush uses site alias files to store context data. (Aegir still uses Drush 4)

drush help site-alias

Copy to ~/.drush, rename aliases.drushrc.php or further.

drush ev 'print_r(array_keys(drush_sitealias_get_record("@server_master")))'
drush ev '$a = drush_sitealias_get_record("@gk.dev"); print_r($a["path-aliases"]);'

Deployment

To sort with Aegir#Remote

drush help rsync
drush help sql-sync

Debugging

Logging

  • https://www.drupal.org/project/error_log -Once Drupal bootstraps, it stops sending errors to PHP's error log — which could be the web server error log, syslog or stderr on the command line. Error Log module adds the PHP error log as a Drupal logger implementation, so errors will once again appear in the same log or console that they appeared in before Drupal bootstrapped.



  • https://www.drupal.org/project/monolog -integrates Drupal with the fantastic Monolog library by Seldaek to provide a better logging solution. Some of the benefits of using this module are as follows: Configurable logging levels A multitude of handlers All the power and flexibility of MonologThe Monolog module also has full watchdog integration, so it works with core and contributed modules out of the box.


Troubleshooting

$config['system.logging']['error_level'] = 'verbose';
  # in sites/default/settings/php


Modules


  • https://drupal.org/project/devel_debug_log - a developer module that provides a way for developers to save and display debug messages on a separate page in the web browser. It serves as an alternative to using drupal_set_message() or watchdog() for debugging, and a complementary module to Devel for those who find viewing messages in the browser easier than looking for them, say, in a file.


  • https://www.drupal.org/project/devel_php - The Execute feature has been removed from the Devel module for Drupal 8 since version 2.0. This module re-adds back that feature as an external module. Hence the message "This project is not covered by Drupal’s security advisory policy".



Admin

  • https://www.drupal.org/project/admin_toolbar - The Admin Toolbar module intends to improve the default Toolbar (the administration menu at the top of your site) to transform it into a drop-down menu, providing a fast access to all administration pages.The module works on the top of the default toolbar core module and is therefore a light module and keeps all the toolbar functionalities (shortcut / media responsive).


  • https://www.drupal.org/project/module_filter - quickly find the module you are looking for without having to rely on the browsers search feature which more times than not shows you the module name in the 'Required by' or 'Depends on' sections of the various modules or even some other location on the page like a menu item.


  • https://www.drupal.org/project/total_control - Several overview panes are included for site stats and quick reference. Several administration panes are provided with quick links to content types, menus, taxonomy, and other scattered locations of important Drupal site administration. Several views panes are also provided as well as full-page comprehensive versions of the views with bulk operations. Each views panel pane is customizable via it's pane settings, or override the default views provided to suit your own needs.







  • https://www.drupal.org/project/readonlymode - provides an alternate to the built in Maintenance Mode in Drupal. Instead of displaying a static text file to users while the site is in maintenance mode, Read Only Mode will allow access (reading) of new content while preventing the addition of new content (posting / submitting forms / etc).



Configuration


  • http://drupal.org/project/features - enables the capture and management of features in Drupal. A feature is a collection of Drupal entities which taken together satisfy a certain use-case. Features provides a UI and API for taking different site building components from modules with exportables and bundling them together in a single feature module. A feature module is like any other Drupal module except that it contains additional information in its info file so that configuration can be checked, updated, or reverted programmatically.



  • https://www.drupal.org/project/config_update - contains a base module and a reporting module.Use the base module if another project has it as a dependency (example: Features).The report module supplements the core Configuration Manager module, by providing a report that allows you to see the differences between the configuration items provided by the current versions of your installed modules, themes, and install profile, and the configuration on your site. The report is available from the administration UI, or via Drush commands.


  • https://www.drupal.org/project/config_split - define sets of configuration that will get exported to separate directories when exporting, and get merged together when importing. It is possible to define in settings.php which of these sets should be active and considered for the export and import.







  • https://www.drupal.org/project/config_tools - Stores your current active configuration as yml in a specified directory, Auto commits changes to your configuration to a specified git repository for every configuration change.


Users etc.

  • https://www.drupal.org/project/masquerade - allows site administrators (or anyone with enough permissions) to switch users and surf the site as that user (no password required). That person can switch back to their own user account at any time.





Workflow

Editing of submitted unpublished nodes, updating coordinator contact info, etc.

Rules

  • http://drupal.org/project/rules - The Rules module allows site administrators to define conditionally executed actions based on occurring events (known as reactive or ECA rules).




Other


  • https://www.drupal.org/project/maestro - This is not a just a clever saying. It's true. With Maestro, the method to automate your process starts with our visual workflow editor with which you drag, drop and connect your workflow steps together. The maestro workflow editor can be used by business users to map out their business process.


  • https://www.drupal.org/project/override_node_options - The Override Node Options module allows permissions to be set to each field within the Authoring information and Publishing options field sets on the node form. It also allows selected field sets to be set as collapsed and / or collapsible.
  • https://www.drupal.org/project/business_rules - The Business Rules module is inspired on Rules module and allow site administrators to define conditionally actions execution based on events. It's based on variables and completely build for Drupal 8.





  • https://www.drupal.org/project/custom_add_another - This is a very simple module that allows you to customise the text of the 'Add another item' button on multi-valued fields.If your field supports 'unlimited' values then you are offered the option of customising the 'Add another item' button text. This setting is stored per 'bundle', so you can have different button text if you use the same field in two places.

Setup

Blocks






Context

  • http://drupal.org/project/context - Context allows you to manage contextual conditions and reactions for different portions of your site. You can think of each context as representing a "section" of your site. For each context, you can choose the conditions that trigger this context to be active and choose different aspects of Drupal that should react to this active context.


Display Suite

  • http://drupal.org/project/ds - Display Suite allows you to take full control over how your content is displayed using a drag and drop interface. Arrange your nodes, views, comments, user data etc. the way you want without having to work your way through dozens of template files. A predefined list of layouts is available for even more drag and drop fun!


Layout





  • https://www.drupal.org/project/layout_options - This module provides a Layout plugin that allows configuration options to easily be added layouts using using Yaml files and LayoutOption plugins. In most cases, using no code just YAML files.


  • https://www.drupal.org/project/layout_builder_save_and_edit - adds Save and Edit Layout button in layout builder form page which will save Site Builders/Content Editors time by redirecting it to same page in which they can see there recently added changes and can add extra changes for there layout.



  • https://www.drupal.org/project/layout_builder_base - The layout_builder_base module provides you a plugin base to create complex Layouts. It can be used by developers as a base to save time and focus on your styling. This module also provides a submodule wich provides you different layouts that can be used to build pages.


  • https://www.drupal.org/project/layoutcomponents - This module has been based on "Layout Builder" and provides a complete package of components integrated with that system, functionality that is available on Drupal 8 and is already fully supported by Drupal 9.With this module we want to extend the user experience by creating an improved interface, much more customizable and with aspects that are essential for us, such as the live preview of the changes while editing the content.



  • https://www.drupal.org/project/layout_builder_styles - This module allow site builders to select from a list of styles to apply to layout builder blocks and layout builder sections. A "style" is just a representation of one or more CSS classes that will be applied. Additionally, for blocks, a block template suggestion is added for the selected style.









  • http://drupal.org/project/panels_everywhere - Panels Everywhere is an advanced method to completely do away with Drupal's restrictive blocks system and instead use the much more freeing Panels Layout system to control how your pages look. Panels Everywhere modifies the page as it is being rendered to 'wrap' the content in a display and can even take over your page theme to do away with the need for a page.tpl.php.


  • https://www.drupal.org/project/page_manager - This is the Drupal 8 version of Page Manager, formerly part of the CTools module written by merlinofchaosIt supports the creation of new pages, and allows placing blocks within that page.Like Drupal 7's Page Manager, it provides a concept of "page variants", each with their own selection conditions.Additionally, it can be used to take over an existing page, like overriding /node/% to change what is displayed when viewing a node.It utilizes the core Conditions, Context, and Blocks APIs to accomplish this.




  • https://www.drupal.org/project/stacks - Stacks is a system that makes creating complex pages easy for content editors.The system is comprised of ‘widgets’, which are reusable pieces of content that you can place, reuse, and re-arrange on a given page. Stacks has a custom admin interface to help facilitate a great experience for content editors with a workflow that includes a template selection (data collection) and a theme variation option (class based tweaking).

Path

  • http://www.drupal.org/project/pathauto - The Pathauto module automatically generates URL/path aliases for various kinds of content (nodes, taxonomy terms, users) without requiring the user to manually specify the path alias. This allows you to have URL aliases like /category/my-node-title instead of /node/123. The aliases are based upon a "pattern" system that uses tokens which the administrator can change.
    • http://drupal.org/project/subpathauto - The Drupal Path module matches only full URLs when creating SEO-friendly aliases. This module extends that behavior by also matching known sub-paths and replacing them with their respective alias.


  • http://www.drupal.org/project/pathologic - an input filter which can correct paths in links and images in your Drupal content in situations which would otherwise cause them to “break;” for example, if the URL of the site changes, or the content was moved to a different server. Pathologic can also solve the problem of missing images and broken links in your site’s RSS feeds.



  • http://www.drupal.org/project/empty_page - The Empty Page module is a simple empty page solution. It provides an interface that assists in managing "empty" menu callbacks, mostly used for pages that only consist of blocks.


  • http://www.drupal.org/project/xmlsitemap - The XML sitemap module creates a sitemap that conforms to the sitemaps.org specification. This helps search engines to more intelligently crawl a website and keep their results up to date. The sitemap created by the module can be automatically submitted to Ask, Google, Bing (formerly Windows Live Search), and Yahoo! search engines. The module also comes with several submodules that can add sitemap links for content, menu items, taxonomy terms, and user profiles.

Title

  • https://www.drupal.org/project/ot - provides an interface to override/change the title using the Node(node_id), Path/URL and View pages, providing a fast and full access to Administrator.

Menus





  • https://www.drupal.org/project/menu_position - Often times site builders want certain types of content to appear in a specific position in the navigational menu. The simplest solution, adding all of that content individually to the menu system, has performance and usability issues. (Imagine hundreds of menu items added to one spot in the menu.)This module allows for the creation of rules that will dynamically add the current page into the menu system at the requested spots.


  • https://www.drupal.org/project/ultimenu - the UltimatelyDeadSimple megamenu ever with dynamic region creation.An Ultimenu block is based on a menu.Ultimenu regions are based on the menu items.The result is a block contains regions containing blocks, as opposed to: a region contains blocks.

Breadcrumbs




GUI

  • http://drupal.org/project/fancy_login - Fancy Login adds JavaScript based, lightbox-style login functionality to your site. When the user clicks on any link that links to /user/login, they screen dims and a login box is created in the center of the screen.


  • http://drupal.org/project/jeditable - The jEditable module provides integration between Drupal's CCK module and the excellent jQuery plugin, jEditable. It is implemented as a CCK formatter, which makes inline editing possible through regular node displays, Panels, Views, or anywhere else you can place a CCK field.


Typography

  • https://www.drupal.org/project/fontyourface - provides an administrative interface for browsing and applying web fonts (using CSS @font-face, supported in all popular browsers) from a variety of sources. Try it out on simplytest.me.




JavaScript


  • http://drupal.org/project/tipsy - Tipsy is a jQuery plugin for creating a Facebook-like tooltips effect to textareas, textfield, anchors or any other HTML element you specify.

Simplenews

  • Simplenews publishes and sends newsletters to lists of subscribers. Both anonymous and authenticated users can opt-in to different mailing lists. HTML email can be sent by adding Mime mail module.

Creating



Modes


  • https://www.drupal.org/project/entity_form_mode - This module lets you make use of form modes for default entities as nodes, taxonomy terms or comments. It hooks up form modes corresponding to entity form routes. The route to add or edit an entity is called "entity.taxonomy_term.add" or "entity.node.edit_form". All you have to do to display i.e. the edit form in its own form mode is to offer a form mode with the (machine) name "edit_form" (the last part of the route name). This is automatically selected by this module to display the form.


  • https://www.drupal.org/project/form_mode_manager - Provides an interface that allows the implementation and use of Form modes easily without specific development. This module provides different configurations/routes/UI/Additional access control to simplify and enhance the management and development of your different entity forms that allowing you to implement a complex content strategy in simple ways. Form mode manager provides a mechanism fully integrated with the event and routing system to support your custom content entities and flexibility to add some behaviors of entity forms.


  • https://www.drupal.org/project/form_mode_control - This module allows you: to define access to each form mode for the different roles, to define for each role, each bundle of each entity which form mode should be selected by default during the creation and edit of a content. Of course you should grant access before defining this. If a user has multiple roles, the weight of the roles is taken into account (heaviest one), to access any of the form modes—as long as you have the permission—by adding a simple parameter such as the following example: node/add/article?display=form_mode_machine_name.

WYSIWYG

See also WYSIWYG


Inplace / Inline

  • https://www.drupal.org/project/jeditable - The jEditable module provides integration between Drupal's CCK module and the excellent jQuery plugin, jEditable. It is implemented as a CCK formatter, which makes inline editing possible through regular node displays, Panels, Views, or anywhere else you can place a CCK field.



Embedding

Rules

  • https://www.drupal.org/project/fillpdf - Most PDF modules generate PDFs from scratch; FillPDF is not one of those modules. Instead, it lets you fill in existing editable PDFs with data from your Drupal site. Editable PDFs are those forms that let you type into them.

Entities


An entity can be a kind of content stack. An entity base table is tied to fields using bundles. Entity types include node, comment, taxonomy term, user profile, organic group, etc. Entity types can allow bundling or not (creating types of node vs. users, though see the Profile 2 module). Fields are used to store and display various data types, and can be reused across bundles and entities.





  • https://www.drupal.org/project/eck - The Entity Construction Kit (ECK) builds upon the entity system to create a flexible and extensible data modeling system both with a UI for site builders, and with useful abstractions (classes, plugins, etc) to help developers use entities with ease.ECK allows the creation and management of entity types with custom properties; adding bundles to entity types; and fields to bundles, with the help of the Field UI module.



  • http://drupal.org/project/auto_entitylabel - "Automatic Entity Label" is a small and efficient module that allows hiding of entity label fields. To prevent empty labels it can be configured to generate the label automatically by a given pattern.





  • https://www.drupal.org/project/entity_reference_revisions - Adds a Entity Reference field type with revision support.It's based on the core Entity Reference module but allows you to reference a specific entity revision. This is useful for modules like Paragraphs and Inline Entity Form.


  • https://www.drupal.org/project/entity_reference_layout - Entity Reference with Layout empowers content creators to design beautiful pages with structured content (aka Paragraphs). It borrows concepts from other paragraphs-inspired modules like Bricks, and provides authors with a way to visually manipulate referenced entities and create unique page layouts. Entity Reference with Layout leverages Drupal’s core Layout Discovery module.


  • https://www.drupal.org/project/external_entities - This module allow you to connect to datasets from external databases and use it in your Drupal 8 website. While content lives external, Drupal sees those remote entities as internal. This makes it possible to alter the field displays, add references, comments, pathaliases, share buttons, webshop products and more.


Content

  • https://www.drupal.org/project/multiversion - convert all core content entities on your site to be revisionable. This includes but is not limited to, nodes, taxonomy terms, comments, block content.It also enhances the Entity API by providing a global identifier for all revisions, handling revision trees (by tracking revision parents) and changing the delete operation to write a new "deleted" revision so that it can be restored if needed.


  • https://www.drupal.org/project/node_keep - Adds two base fields to all nodes.Node keeper: prevents people who don't have the 'bypass node access' permissionfrom deleting nodes where that checkbox is enabled.Alias keeper: prevents people who don't have the 'administer node_keep per node' permissionfrom changing the node's alias if the Alias keeper checkbox is checked. Is onlyinstalled if the 'pathauto' module exists.


  • http://drupal.org/project/delete_all - This module is used to delete all content and/or users from a site. This is mainly a developer tool, which can come in handy in several cases, listed below.





Files

  • http://drupal.org/project/filefield_paths - The File (Field) Paths module extends the default functionality of Drupal's core File module, Image module and many other File upload modules, by adding the ability to use entity based tokens in destination paths and file names.


  • https://www.drupal.org/project/system_stream_wrapper - Provides stream wrappers to access module, theme, profile, and library files and directories. Note these stream wrappers are read-only as none of these files or directories should be write-able by your webserver.

Comments


  • https://www.drupal.org/project/bestreply - Best reply module allows node authors to mark a particular comment as the best reply. It aims to encourage quality comments and to give some recognition to people posting quality responses.


Feedback

  • https://www.drupal.org/project/admin_feedback - Module for gathering user feedback on content (nodes). Allows users to submit feedback to content via ajax requests (so the client is never redirected). Dashboard is provided for the administrators to easily monito, analize and inspect the content feedback.


Media



  • http://drupal.org/project/image_resize_filter - This filter makes it easy to resize images, especially when combined with a WYSIWYG editor such as tinyMCE, CKeditor etc. Users never have to worry about scaling image sizes again, just insert an image and set it's height and width properties in HTML (this is done automatically by WYSIWYG editors) and the image is resized on output to match the HTML.


  • http://drupal.org/project/insert - Insert is a utility that makes inserting images and links to files into the body field and other WYSIWYG editors or text areas much easier by adding a simple JavaScript-based button and optional controls to file and image fields. Images may be inserted using any image style preset. Insert may also be interfaced to by other modules for inserting custom content.


  • https://www.drupal.org/project/media_responsive_thumbnail - This module adds a new field formatter for Entity Reference fields which target Media entities. Essentially, it allows you to display a Media Entity Reference field just like you normally would an Image field with a Responsive Image formatter.



  • https://www.drupal.org/project/remote_stream_wrapper - Provides the ability to use external files with file fields without saving the files to your local files directory. Also provides a 'Remote URL' browser plugin for Media.By default the module adds support for any URL using http://, https://, or feed://. Also note these stream wrappers are read-only and cannot perform any writing operations.


  • https://www.drupal.org/project/media_entity_remote_image - This module provides a basic Remote Image media entity type which allows embedding of images from any remote URL. The entities are simply rendered as an <img> tag with the src attribute set the to the URL that is saved on the entity. The limitation to this approach is that you cannot leverage Drupal Core's image styles since the images are not copied to the site's local file system.


  • http://drupal.org/project/mediawiki_api - This module provides an input filter which allows the conversion of content marked up using MediaWiki syntax to html for display on your drupal site, by using the "parse" feature of the MediaWiki API.



  • https://www.drupal.org/project/representative_image - Allows you to define representative image or media fields for entities like nodes, taxonomy terms and the like. These can then be used in Open Graph meta tags (via tokens); as fields in views; or embedded as tokens. The media module is also supported. A default image can be defined for those entities without images.


  • https://www.drupal.org/project/background_image - If your site is designed around utilizing background images, then this module is for you! Whether you need a surgical implementation that only administrators/developers can implement or provide the ability to allow users to attach their own background images to entities, this module has you covered.


  • https://www.drupal.org/project/flexslider - Flex Slider module integrates the Flex Slider library with Drupal and several contributed modules which allows you to build responsive, resizable slideshows. Meaning the slideshows automatically adapt to the size of the browser window or device.

Styles

  • https://www.drupal.org/project/image_style_generate - Image Style Generate allows a site administrator to quickly create image styles in bulk, based on a defined set of rules and patterns. It provides examples of how migrations can employ the module's capabilities.

Generation etc


  • https://www.drupal.org/project/textimage - adds text to image functionality using GD2 and FreeType, enabling users to create crisp images on the fly for use as theme objects, headings or limitless other possibilities.


  • https://www.drupal.org/project/image_effects - The Image Effects module provides a suite of additional image effects that can be added to image styles. Image Effects tries to support both the GD toolkit from Drupal core and the ImageMagick toolkit.


Admin

  • https://www.drupal.org/project/media_duplicates - This module allows the comparison, detection and restriction of duplicate mediaentities within a site.Cleaning up the duplicate media items is currently outside the scope of this module. That's because it's a hard task. Depending on media usage in fields, usage across translations, usage in token embedded media, usage in config (blocks, etc).

Loading

  • https://www.drupal.org/project/blazy - Provides integration with bLazy and or Intersection Observer API, or Native lazy loading to lazy load and multi-serve images to save bandwidth and server requests. The user will have faster load times and save data usage if they don't browse the whole page.


Lightbox / gallery



  • https://www.drupal.org/project/colorbox - a light-weight customizable lightbox plugin for jQuery. This module allows for integration of Colorbox into Drupal.Images, iframed or inline content etc. can be displayed in a overlay above the current page.



  • https://www.drupal.org/project/touchtouch - front-end gallery for images in fields, based on an extended(*) version of the jQuery-plugin by Martin Angelov described onhttp://tutorialzine.com/2012/04/mobile-touch-gallery/


  • https://www.drupal.org/project/shuffle - provide a Drupal integration with the jquery library Shuffle. This module provide : A views style plugin for displaying rows in a shuffle grid A field formatter for displaying images attached to an entity in a shuffle grid

Optimisation



Audio

  • http://drupal.org/project/audiofield - allows you to upload audio files and automatically displays them in a selected audio player. Currently it supports 6 players and it provides API for easy addition of new players.


Dates, times and events


  • http://drupal.org/project/calendar - will display any Views date field in calendar formats, including CCK date fields, node created or updated dates, etc. Switch between year, month, and day views. Back and next navigation is provided for all views. Lots of the Calendar functionality comes from the Date module, so any time you update the Calendar module you should be sure you also update to the latest version of the Date module at the same time.





  • https://www.drupal.org/project/smart_date_calendar_kit - Installs a preconfigured view to use Smart Date values in a Fullcalendar View. Extends on and requires Smart Date Starter Kit so review that module and its notes about the default configuration provided.This module is not intended to be a robust solution, but a starting point. It could be useful for evaluating the basic functionality of Smart Date and Fullcalendar View, or it could be the starting point for a more customized solution.






  • https://www.drupal.org/project/field_timer - provides field formatters for core module Datetime which display timer or countdown. 3 field formatters are provided: simple text and 2 formatters based on jQuery plugins County and jQuery Countdown.If you are looking for a configurable countdown/timer, this module is for you. It allows to configure backgrounds, effects, formats, language of timer, etc.

Ctools

Chaos tool suite (ctools) suite is primarily a set of APIs and tools to improve the developer experience. It also contains a module called the Page Manager whose job is to manage pages. In particular it manages panel pages, but as it grows it will be able to manage far more than just Panels.

For the moment, it includes the following tools:

  • Plugins -- tools to make it easy for modules to let other modules implement plugins from .inc files.
  • Exportables -- tools to make it easier for modules to have objects that live in database or live in code, such as 'default views'.
  • AJAX responder -- tools to make it easier for the server to handle AJAX requests and tell the client what to do with them.
  • Form tools -- tools to make it easier for forms to deal with AJAX.
  • Object caching -- tool to make it easier to edit an object across multiple page requests and cache the editing work.
  • Contexts -- the notion of wrapping objects in a unified wrapper and providing an API to create and accept these contexts as input.
  • Modal dialog -- tool to make it simple to put a form in a modal dialog.
  • Dependent -- a simple form widget to make form items appear and disappear based upon the selections in another item.
  • Content -- pluggable content types used as panes in Panels and other modules like Dashboard.
  • Form wizard -- an API to make multi-step forms much easier.
  • CSS tools -- tools to cache and sanitize CSS easily to make user-input CSS safe.
  • Ctools Plugin Stub is a Drush plugin that can help you generate code stub files for ctools plugins. I wrote this plugin after having consistently messed up names of hook implementations in plugins over a long period. Plugin Stub does not write actual code that *does* stuff for you, but it sets you up so that all you have to do to get started is to fill in the capitalized parts of the generated file and start writing code that *does* stuff.


Views

mess!!!


  • https://www.drupal.org/project/views_extras - provide extra arguments for contextual filters based on session, cookie or token. This extends filter functionality to pass cookie, session variable or token as argument to views.




Administration



Structure

  • http://drupal.org/project/semanticviews - This Views plugin makes unformatted styles, field row styles and other output more readily configurable without needing to override template files.
