Save time

Forgot about php timeout (and some restrictions of php)

Don't need remember all.

Automatization (repeating of actions)

some other restrictions of php)

We can hadle have processes

Batch processes

Using bash scripts

Forgot about some issues in drupal web-
interface using

Don't need pay too many attention for file
system (locations of some module folder and
other)

8. Automatization (repeating of
actions)

Use bash aliases

Launching by cron


19. Build your drush
extention

20. Create COMMANDFILE.drush.inc
Drush searches for commandfiles in the following
locations:

The "/path/to/drush/commands" folder.

Folders listed in the 'include' option (see
`drush topic docs-configuration`).

The system-wide drush commands folder,
e.g. /usr/share/drush/commands

The ".drush" folder in the user's HOME folder.

All modules in the current Drupal installation

21. Implement
COMMANDFILE_drush_help()
function sandwich_drush_help($section) {
switch ($section) {
case 'drush:make-me-a-sandwich':
return dt("... brief help summary
goes here ...");
}
}

22. Implement
COMMANDFILE_drush_command()

'aliases': Provides a list of shorter names for the command.

'deprecated-aliases': Works just like 'aliases', but does not appear in help.

'callback': Name of function to invoke for this command

'callback arguments': An array of arguments to pass to the callback.

'description': Description of the command.

'bootstrap': Drupal bootstrap level. Valid values are:

DRUSH_BOOTSTRAP_DRUSH

DRUSH_BOOTSTRAP_DRUPAL_ROOT

DRUSH_BOOTSTRAP_DRUPAL_SITE

DRUSH_BOOTSTRAP_DRUPAL_CONFIGURATION

DRUSH_BOOTSTRAP_DRUPAL_DATABASE

DRUSH_BOOTSTRAP_DRUPAL_FULL

DRUSH_BOOTSTRAP_DRUPAL_LOGIN

DRUSH_BOOTSTRAP_MAX

23. Implement
COMMANDFILE_drush_command()

Usefull functions:

drush_prompt($prompt, $default = NULL,
$required = TRUE);

drush_print($string);

drush_confirm($message);

Example of input:
$stdin = fopen("php://stdin","r");
$macros_name = fgetc($stdin);
…

24. Drush_macros: simple drush
extention for example.

Link for downloading will be later

Aim: recording and launching commands by 1
commands, recording drush/bash commands,
saving in drush inveronment

25. Using drush_macros

drush cli
mstart — start «recording» bash/drush commands
mstop — stop «recording» bash/drush commands
macros-save — save queue of commands by 1
name
exit — exit from drush cli mode

After that we can run queue of commands by 1
command in drush cli
