Checking Joomla version >=3.8 via bash

[jobst]

Hi
I used to be able to check the current Joomla version <3.8 via bash quite easily:

Code: Select all

php -r 'define("JPATH_PLATFORM","TEST");require("SITEPATH/libraries/cms/version/version.php");$version=new JVersion;echo $version->getShortVersion();'

Changing this to the new version.php file and changing class name

Code: Select all

php -r 'define("JPATH_PLATFORM","TEST");require("SITEPATH/libraries/src/Version.php");$version=new Version;echo $version->getShortVersion();'

yields an error

Code: Select all

 PHP Fatal error:  Class 'Version' not found in Command line code on line 1

Note: there is nothing wrong with the path, when I do an "ls SITEPATH/libraries/src/Version.php" there is no error. Also note I changed to "$version=new JVersion;" still the same error.

What am I doing wrong?
thanks

All classes in the libraries/src directory use PHP namespaces. So the class name is not just "Version". It is actually "Joomla\CMS\Version" (a combination of the "namespace" line in the file plus the class name).

Sorry, I sort off understand but this doesn't help me.
Not sure how to implement this in my code ...

Use this:

Code: Select all

$version=new Joomla\CMS\Version;
