Just a quick heads up Leevi. I had to change the file upload code to:

'upload_preferences' => array(
    1 => array(                                                                                 // ID of upload destination
        'name'        => 'Staging Image Uploads',                          // Display name in control panel
        'server_path' => '/home/user/example.com/staging/images/uploads/', // Server path to upload directory
        'url'         => 'http://staging.example.com/images/uploads/'      // URL of upload directory
    )
),

Otherwise it killed the script.

I'm wondering something pretty basic. Where do you set the db info for the production db if not in this file? Do you just set it normally through the expression engine install on the production server itself and use this file to identify the dbs for the other environments?

@andyhoman sorted!

@wssrstrm The db info for the production environment are entered near line 123 of the script. It woudn't be very handy if you ended up with configuration data in multiple files.

@leevigraham The NSM_SITE_URL near line 62 ends up WITH a trailing /. All other variables based off of this like theme_folder_url use a / between NSM_SITE_URL and the rest of the variable. Ending up with url.com//themes/. Is this intentional?

@ginkelb I'll update the NSM_SITE_URL now.

I think an important config is missing (excellent bootstrap btw).

http://expressionengine.com/wiki/EE_2_Config_Overrides
[base_url] => http://local.ee2.template/

site_url($uri = '') from ->helper('url') in Config.php as part of CI uses base_url to define paths.

This caught me out when developing a module using site_url() for the 'action' part of a form_declaration. I'm not sure why site_url doesn't use 'site_url' from the config array, maybe it's a hangover from CI and EE uses 'site_url'.

Easy fix, I've included after
'site_url' => NSM_SITE_URL,
'base_url' => NSM_SITE_URL

• Version 1.9

• - Added $config['third_party'] param to ease updating
  

• - Added $config['base_url']
  

• - Moved webmaster_email config into dev environment
  

missing a comma after:

'base_url' => NSM_SITE_URL

@alexroper wish I would've see your comment an hour ago. I was tearing my hair out!

@alexroper Just found out about the comma

@leevigraham EE v2.5.3 adds a couple other hidden config variables for third-party themes:

'path_third_themes' => NSM_BASEPATH . '/content/themes/third_party/',
'url_third_themes' => NSM_SITE_URL . '/themes/third_party/',

@leevigraham Also, the 'third_party' variable should be changed to 'third_party_path':

'third_party_path' => NSM_BASEPATH . '/third_party/',

@alexroper took me a while but I've updated based on your comments

@leevigraham you've got syntax errors now on Line 154 and 177 (double braces)

line 369 should be:

$env_config['upload_preferences'] = array(

@leevigraham Line 7,8 should be:

• require_once instead of require (see line 9)
