README

Purpose

This drush extension implementes commands to check for new versions of installed modules and update them without issuing drush dis module && drush pm-uninstall module. On update it uses a custom hook called hook_vm_update(). With this the module can decide if there is something to do on update. And return true on success or false on failure. It has the advantage that the hook_install() and hook_uninstall() is not issued. (E.g. loosing all data if the hook_uninstall() cleans a table in the database.

Travis build status

Obtain sources

Get it from packagist.org

To obtain the sources via composer add the following lines to your composer.json file or complete the list of dependencies.

"require": {
    "liip/drushversionmanagercommand": "1.*"
}
...
"extra": {
    "installer-paths": {
        "path/2/drush/commands/{$name}/": [
            "liip/drushversionmanagercommand"
        ],

Then execute the following commands on the command line:

$> curl -s http://getcomposer.org/installer | php
$> php composer.phar install

Getting started

Sources fetched? Brilliant.. now we can start using the module updater. In your ModuleName.install file implement the hook_vm_update().

/**
 * Update script
 *
 * @return bool
 */
function ModuleName_vm_update()
{
    // clean out no longer used variables
    variable_set('ModuleName_some_variable', 'myValue')
    
    // this update was successful
    return (bool) variable_get('ModuleName_some_variable', false);
}

Add a version to the ModuleName.info file:

// ...
version = 1.0
// ...

Let composer post_install or post_update handle module updates

#!/bin/bash
DRUSH="drush"

# store version number from installed modules
$DRUSH php-script scripts/invoke_module_update 

# update modules if needed
$DRUSH php-script scripts/update_module_versions

Aliases: vm-info

Update all modules

$ drush vm-update --all
Updating ModuleName1 ...                                                                   [success]
Nothing to update for module »ModuleName2«                                                 [warning]

Update a subset of all enabled modules

$ drush vm-update ModuleName1, ModuleName2
Updating ModuleName1 ...                                                                   [success]
Updating ModuleName2 ...                                                                   [success]

Get short list of all modules were an update is available

The neat thing is that you can copy and paste the out put directly to vm-update and not using the --all switch there. This will make it segnificantly faster.

$ drush vm-info --all --short
ModuleName1, ModuleName2, ..., ModuleNameN

Get full information about module updates

The --full switch is not only optional but also the default if --short is not declared. As you'd guess ModuleName2 has no update available.

$ drush vm-info --full --all
Title                         :  Title of ModuleName1
Name                          :  ModuleName1 
Version                       :  0.1 
Update available to version   :  1.5
 
Title     :  Title of ModuleName2
Name      :  ModuleName2 
Version   :  7.x-2.x-dev
