Devel All commands in devel: (devel) … devel-reinstall (dre) Disable, Uninstall, and Install a list of projects. ... fn-view (fnv) Show the source of specified function or method. All commands in devel_generate: (devel_generate) generate-content (genc) Create content. ...
Drush Make 1. Projects: drupal, pressflow, modules, themes. Could be downloaded from repository, by direct link, by name. 2. Libraries: any files you need to use.
Example of Drush Make file projects = drupal projects = apachesolr … libraries[SolrPhpClient][download][type] = "get" libraries[SolrPhpClient][download][url] = "http://solr-php-client.googlecode.com/files/SolrPhpClient.r22.2009-11-09.tgz" libraries[SolrPhpClient][destination] = "modules/apachesolr"
Module Builder Examples: drush mb my_module menu cron nodeapi drush mb my_module menu cron --write --name="My module" --dep="forum views" drush mb my_module menu cron --add
Backup and Migrate All commands in backup_migrate: (backup_migrate) bam-backup (bb) Backup the site's database with Backup and Migrate. bam-backups Get a list of previously created backup files. bam-destinations Get a list of available destinations. bam-profiles Get a list of available settings profiles. bam-restore Restore the site's database with Backup and Migrate. bam-sources Get a list of available sources.
Part 3 How Drush helps during development process.
Base facts 1. Site URL is http://example.dev. 2. Version of Drupal – 7. 3. Additional modules: admin_menu, pathauto, views. 4. Custom modules: one module with some features will be created. It will use database. PS: no Drush Make because it's not interesting.
Step 3 ss81@laptop:~/session$ drush si --db-url =mysql://root:111@localhost/session --account-name =ss81 --account-pass =qwerty You are about to create a sites/default/files directory and create a sites/default/settings.php file and DROP your 'session' database and then CREATE a new one. Do you want to continue? (y/n): y Starting Drupal installation. This takes a few seconds ... [ok]
Step 4 ss81@laptop:~/session$ drush dl admin_menu views pathauto token … ss81@laptop:~/session$ drush en -y admin_menu views pathauto token The following projects have unmet dependencies: views requires ctools Would you like to download them? (y/n): y Project ctools (7.x-1.0-alpha4) downloaded to /home/ss81/session/sites/all/modules/ctools. [success] ... That's all. We installed a site! Let's create a custom module.
Step 5 ss81@laptop:~/session$ drush mbdl Hook files have been downloaded to public://hooks and processed. We need to download hooks definitions before we can generate a module. There are 33 files with different hooks, so this could be used as a good manual.
Step 6 ss81@laptop:~/session$ drush mb my_module menu permission user_load --write --name ="My module" --desc ="My test module“ --pachage ="test" --noi Proposed my_module.module: … code of the module... Proposed my_module.info: … code of the info file...
